How to properly charge a new battery on an iPhone. How long to charge an iPhone for the first time

Useful tips

With every new iPhone released, users have almost the same questions. This time the question is still interesting: “How to properly charge the iPhone 8 and iPhone 8 Plus?”

I have been friends with iPhones for quite a long time and know a lot of information on this matter. Therefore, I want to share it with you and I think you will definitely find something useful for yourself.

How to charge a new iPhone 8 or iPhone 8 Plus for the first time?

The moment has come when you have made a very long-awaited purchase and now the iPhone 8 or iPhone 8 Plus is in your hands. You actively use it and at the end of the day a problem appears: “How to charge your brand new iPhone 8?”

I can tell you that the first charge and the hundredth charge will not differ from each other at all. Now all the elements are stuffed with controllers and doing something wrong is a very difficult task.

Therefore, we do everything the old fashioned way: when you see that the phone has reached less than 20 percent, you can discharge it a little more or immediately put it on charge.

Nowadays everything is measured in the number of charge cycles and you will most likely experience problems with the battery somewhere in the third year of use. If something is wrong, then just check the volume Battery program Life.

There is a type of user who uses their devices in a very tough mode and, constantly playing or simply very actively using the gadget, charges several times a day. In this case, you may have to replace the battery after a year.

Therefore, here are a couple more useful tips for you:

if you buy third-party accessories for your devices, they must be certified by Apple (we are looking for the “Made for iPod/iPhone/iPad” logo);
We try not to use Chinese cables and blocks. In the best case, the battery will quickly lose its capacity, in the worst, the device may fail or even catch fire;
You can and even need to use an iPad charger;
if we love Power Bank, then we buy proven brands.

I’ve also heard a lot that fast charging is very harmful for devices, and this is evidenced by the information about electric cars. There is a recommendation to carry out this kind of procedure maximum once a month.

With phones the story is a little different, because a lot has already been invented here different technologies. Nobody can tell you 100 percent whether it is harmful or not.

Therefore, we charge as you like, the main thing is within the normal limits and simply following the recommendations from the manufacturer.

How to quickly charge iPhone 8?

Let’s say your iPhone 8 is dead and the problem is, you have to leave in about half an hour. We don’t have a Power Bank in stock, but we need the phone in working condition.

The following methods may work here, depending on the situation:

No additional accessories. We turn on Airplane mode and put it on charge, so the phone will not use the network and wi-fi, which will give a small increase in speed. With the device completely turned off, the result will be even better.
You are lucky and have a 2 Amp unit. In this case, everything is much simpler, because modern iPhones support this type of charging and you will get incredible speed.

Unfortunately, in included 1 Amp unit only. While all other manufacturers have long been allowing their users to enjoy normal 2 Ampere units right out of the box.

So better solutions You probably won’t find anything better than just buying a 2 A unit like the iPad’s. If anything, the full name is “Apple USB 12W Power Adapter.”

This generation also has fast charging, but this story deserves a separate point and we’ll get to it right now.

How to use fast charging on iPhone 8?

Charging your smartphones is practical, fashionable, and this opportunity is present in all modern brands. Apple ended up lagging behind here, but they still did it and added this feature.

True, as always, they did not do the same as everyone else and many are not very happy with their actions. At the presentation they said 50 percent in 30 minutes, but in reality we spend a lot of money to get this feature.

In order to achieve this result, you need to purchase:

Power adapter Apple USB-C power 29 W, 61 W or 87 W (RUB 3,590.00/RUB 5,490.00/RUB 5,790.00);
USB-C/Lightning cable (RUB 1,990.00 for 1 m, RUB 2,690.00 for 2 m).

Having bought all this, you end up with a very tidy sum. But only if this condition is met, you will receive fast charging on your iPhone 8.

As an alternative, I suggest just buying the same 2 Amp power supply as the iPad for RUB 1,590.00. and enjoy life. Of course, not so fast, but it will be enough for you and much cheaper.

How to charge iPhone 8 wirelessly?

To add even more wood to the fire, let's also talk about wireless charging. Here, in principle, the same story as in the previous paragraph.

This feature has been available in Samsung for many years and in 2017 year Apple I finally decided to add it to myself. Still the same Qi standard.

So if you don’t like wires, then buy a special stand, and simply by placing your smartphone on it, charging begins.

The advantage is that there are already enough manufacturers here and you can find cheaper options than in Apple store. We are just looking for a Qi standard.

How to charge iPhone 8 in the car?

If you are the owner of both an iPhone 8 and a car, then the question arises about charging your smartphone in the car.

It generally depends on the car. But if this is the most standard option with a cigarette lighter, then there are two courses of events:

we buy car charging and then we insert our own cable into it;
We buy a car charger with a built-in cable.

Naturally, the rule with certification from Apple also works here and we are also looking for the “Made for iPod/iPhone/iPad” icon. Or at least we buy proven brands so that we don’t burn anything.

Last week, a story became popular on the Internet, the heroes of which were an unknown Internet user and Apple's senior vice president of software, Craig Federighi. The first sent a letter to the head of the corporation, Tim Cook, in which he asked whether it was necessary to remove tasks from the list of running applications in order to save battery power. “No and no again,” Federighi answered for his boss on his own Twitter.

Soon after this, foreign and domestic media began publishing a link to a special section on the Apple website, which talks about how to increase the operating time of an iOS device without recharging and extend the overall life of the built-in battery.

The page that has gained new popularity notes that the term “lifetime” in relation to a battery means exactly the period that elapses between two charges, and the definition of “lifespan” implies the time after which the battery needs to be replaced with a new one. Exactly how to extend both - translated by RG Digital.

1. Apple advises updating software promptly, as updates often include new energy-saving technologies.

2. You should avoid too high and too low temperatures when using gadgets - this applies to tablets, smartphones, and laptops. The range of comfortable temperatures is from 16 to 22 degrees Celsius, the upper limit is 35 degrees Celsius. Charging at more high temperatures may cause permanent damage to the battery. Use in cold conditions may reduce the time battery life, but this phenomenon is temporary.

3. Remove cases from devices while charging. This will help them avoid overheating as charging can cause excess heat.

4. Keep gadgets half charged if you leave them for a long time. A completely discharged battery may completely lose the ability to charge in the future. In turn, a battery charged at 100 percent for a long time may lose some of its capacity. It is recommended to store devices at a temperature not exceeding 32 degrees.

5. Available for iPhone and iPad additional ways increase battery life. The first one is to install automatic brightness, in which the device adapts to lighting conditions. The second is to keep Wi-Fi on all the time, since this access method consumes less energy.

6. iOS 9 introduced a power saving mode that warns the user when the battery is low and also reduces power consumption by disabling iCloud synchronization and AirDrop data transfer. At the same time, the ability to make calls, send SMS and access the Internet will remain. When the device is charged, the saving mode is automatically turned off.

7. According to Apple, iOS 9 has become the most energy-efficient operating system, since it has the ability to find out which applications are using the most battery power. If desired, the user can limit the background activity of the most "gluttonous" programs.

Owners of a fashionable gadget know that they need to charge their iPhone every day. This becomes a habit - I put it on exercise in the evening, in the morning full battery. And some people believe that you can charge your iPhone only after it is completely discharged. Whose opinion is correct?

According to experts, lithium ion batteries needs to be charged every day. This also applies to charging iPhones. If you want your battery to last a long time, you don't need to charge it to capacity.

How to properly charge an iPhone

Experts have the following opinions on this matter:

You need to charge your phone often. That is, if the charge level has not yet reached 100%, then there is no need to wait for this. And there is also no point in allowing the battery to completely discharge every day until the device is turned off. This mode is detrimental to the phone, so it is better to charge the iPhone several times a day a little at a time rather than from 0 to 100%.
The charge level must be kept above the average level. That is, these numbers can range from 40% to 80, and you can connect even when the battery shows a 50% charge. But it’s best to turn off charging when the battery is not yet fully charged. A 90% charge is sufficient.
Full discharge and 100% charge – once a month. Battery drained to complete shutdown devices can be charged to the maximum level - 100%.
Many Apple product users find it convenient to charge their phone at night. In the morning the battery shows full charge. But in this way you can quickly drain the battery, because it does not charge throughout the night, and then remains in standby mode, but on recharge. This way the battery deteriorates faster.

How to properly charge an iPhone - tricks or how to extend battery life

To ensure your battery lasts longer, consider the following:

if you constantly charge the battery to 100%, then such a device will last for a maximum of 500 cycles, while when the battery is charged only 70%, the battery life increases and then the battery will last for 2000 charging cycles;
Do not expose the device to hypothermia or overheating. The extreme temperature range is: from +15 degrees to +40 degrees. If there is a record high outside in the summer, the iPhone battery may lose 35% of its capacity;
The battery tolerates overheating worse than hypothermia. Therefore, it is better to refuse a wireless charger or use it in case of emergency, when it is not possible to connect to the network. All wireless charging creates excess heat and wears out the battery life;
You can extend the life of your iPhone battery in this way: lower the screen brightness, turn off those applications that use GPS navigation. If the signal is bad and the phone is in standby mode, then it is better to turn on the “Airplane” mode;
turn on the “Energy Saving” mode. To do this, go to “Settings” - “Battery”, make the appropriate mark “On”.

Actively used laptops (Macbook Pro, Macbook Air), smartphones (iPhone) and tablets (iPad 4, iPad mini) constantly need recharging. However, not everyone knows how to charge correctly to extend the life of the battery. So you can hear two different opinions, one of which says that the battery of any mobile device, be it Macbook Air or the iPhone 5 should be completely discharged and then charged to 100%, and the second advises maintaining the device's charge level at about 40-80% by regularly recharging the devices.

These tips are not without meaning and have a very real background. In the recent past, nickel batteries were common, which had the so-called “memory effect”. So they had to be completely discharged. Nowadays laptops, smartphones and tablets (especially when it comes to mobile Apple technology) mainly lithium-ion batteries are installed, for which this problem is not so acute. However, in order to prolong their uninterrupted operation as much as possible, since their service life is measured in years, it is necessary to adhere to certain rules of use.

1. Devices require regular charging.

The device should not be completely discharged; it needs regular recharging. It would be optimal to recharge after the battery has been discharged by 10-20%, without lowering the charge level even to 50%.

2. It is unacceptable to keep devices charged for a long time.

Lithium-ion batteries do not need to be fully charged at all times. The recommended charge level should be between 40 and 80%, so it is advisable to adhere to these limits. After charging the device to 100%, it is unacceptable to leave it further charging.

Sometimes this seems very convenient, but you should remember that this is what can shorten the battery life. Even if the device is charged overnight, you should make sure that this is done using special energy-saving sockets that will allow you to turn off charging after a certain number of hours.

High-quality phones and laptops have a built-in charge controller, which allows them to signal when they are fully charged and even turn off charging themselves after that. Devices with this function can be kept connected to the network at all times.

3. Once a month, the battery must be discharged to zero and fully charged.

Occasionally full iPhone drain or an iPad is still necessary. Once a month it is recommended to carry out a full cycle of discharging to zero and charging to 100%, which allows you to calibrate the device. After all, on a smartphone or tablet, the remaining charge is most often indicated either as a percentage or in hours and minutes, after which complete discharge will occur. But frequent use of small charges leads to incorrect operation this function, therefore it is necessary to perform a calibration to return the accuracy of these readings.

4. It is unacceptable to overheat the device.

The battery life of, for example, an iPhone device may also be reduced due to overheating, so you should not allow it to be exposed to high temperatures.

By following these recommendations, you can significantly increase battery life. However, you should not panic too much if you are not always able to perform optimal charging. Even if the device is discharged once again to zero or there is a need to charge it to full before a long journey, this should not become a reason for unnecessary worries.

Did you ask if you can charge your iPhone using an iPad charger? Which adapter should I choose? Is it possible to use the phone while it is connected to the outlet? Now I'll tell you everything.

How to charge an iPhone

You cannot charge your iPhone incorrectly; it can be charged quickly or slowly. What does this depend on? From a specific smartphone and power supply.

Charging the iPad helps. But not always.

A minute of statistics: iPhone 5s consumes 1A, iPhone 5 takes the same. Connecting them to the iPad power supply is no use. But the iPhone 6+ and 6s+ eat up 2.1A, so it makes sense to connect a unit from the iPad. Let's check it out.

We take two iPhone 6+, connect a standard 1A charger to one, and connect a 2.1A iPad unit to the second. In 10 minutes the first one was charged by 4%, and the second by 10%, profit! To speed up charging, use airplane mode, the difference is small, but the method still helps.

Charging the battery while in use

You can use the device while charging, it will just take a little longer to charge.

Current strength decides

When buying a multiport charger, pay attention not only to the current strength, but also to the support for Quick Charge, this will greatly speed up the process. This cool theme doesn’t work for iPhone, but if you have a Galaxy S6, then feel like a king.

The same principle applies to Power Bank: it is better to take a charger that produces a current of 2A. It won't kill your smartphone, but you can always charge your tablet. Whereas with an external 1A battery this situation is basically impossible.

iPhone not charging? Check your Lightning cable

Bought a Chinese Lightning for 100 rubles at a stall, but your iPhone refused to charge? Before buying, be sure to look at the packaging; if you take proven, certified Belkin or Griffin products, then everything is ok. But when the box doesn't say "made for iPod, iPhone, iPad", then you can fly with the cable.

No need to replace the battery

A modern battery has a lifespan of about 1000 cycles, which is about 3 years of operation. So you’d rather replace your old phone with a new one because you’re just tired of it, than really start to suffer because of a dead battery. Unless, of course, you killed it with Chinese wires and a worthless power bank.

To prevent your iPhone from burning

Achtung! Don't charge your iPhone while lying in bed. Just imagine: you stare at the screen, fall asleep, the phone falls on the bed or under the pillow, under the blanket, overheats and FIRE. Do not do that.

As you know, owners of iOS devices charge their devices in different ways. Some believe that you need to resort to this procedure every day. Others are sure that the charge must run out completely, and only then do you need to connect the gadget to the outlet.

Probably no one can say 100% how this procedure should be done. The only thing you can trust is this Apple recommendations on this matter, posted on the company’s website on the Internet.

How to properly charge the new iPhone 5S - another one complex issue. They are asked by many new owners of a gadget of this model or the iPhone 6, as well as any other version of the Apple phone.

A number of users are surprised by this recommendation that charging the device before maximum value, that is, up to 100%, harmful. It must be said that many experts also believe that it is necessary to keep the battery charge level within 50-80%. Based on the results of some tests, it was determined that a device charged to 100% can easily work for at least 500 cycles. While the battery, the charge value of which stopped at 70%, withstood more than 1000 cycles. Thus, everything is clear with repeated procedures. But what about the very first charge?

This is where things get a little more complicated. Discussions are still ongoing on this matter, and no consensus has been reached.

In this article we will try to figure out how to charge a new iPhone 5S or 6 for the first time. Here are some tips, including: provided by the manufacturer. By following all the recommendations exactly, you will significantly extend the life of the battery of your iOS device.

How to properly charge iPhone 5S or 6

Of course, the battery of the new iPhone 6 (or another version of the gadget from Apple) is already equipped with a certain amount of energy; it needs to be recharged. Moreover, the duration of this process should be at least 12 hours, and preferably a day.

The charging operation itself looks like this:

Connection USB cord from the charger to the iPhone.
Connecting the charger to the mains.
Leaving the gadget for 12-24 hours.

This way, the device will go through the first charging cycle, after which it will be necessary to completely discharge the battery. And exactly 100%. To do this, you need to use the device as actively as possible. After this, you need to proceed to the second cycle, namely, you should completely repeat the steps of the first.

At the end of the second cycle, the device again discharges followed by charging. And the more repetitions of this procedure are performed, the longer the iPhone, equipped with more energy, will work.

Note that after 1-2 cycles, the gadget discharges in a natural mode. But it is recommended to speed it up. For this purpose, you can download voluminous software using Wi-Fi or turn on a long video clip.

After 2 years of using the device, it is better to replace the battery with a new one.

While charging, do not leave the phone in the sun. Direct exposure of the device to sunlight should be avoided. Therefore, do not leave your gadget in a hot car or on a windowsill. If the device overheats, liquid will leak from it, and of course, it will soon fail.

Is it right to leave the device on charge overnight?

To give a competent answer to this question, you need to understand the essence of the processes that take place inside the device after it is connected to the power adapter. Let us immediately note that the built-in controller (or module) is in charge of charging the battery. By the way, this element controls this process not only in gadgets from Apple, but also in almost all modern mobile devices.

What is a controller for? To prevent the battery from overcharging. But at the same time, the element helps the phone charge as quickly as possible. At the same time, up to 80% the battery is recharged very quickly, and up to the remaining 20 - at a slow pace.

After the process is completed, the controller turns off the power supply. The system seems to leave the battery alone - and does not allow energy to flow into it, but also does not take charge from the element. At this time, the device itself is charged from a device intended for this purpose. In other words, at this moment absolutely nothing happens to the battery. Thus, the existing popular myth that after a 100% charge the battery begins to work in cyclic mode has no basis. If this were true, the element would wear out very quickly. And, of course, no one needs this.

Let's dwell on one more fact. It is known that every battery can discharge itself. And this process is completely natural. Of course, if the battery is not connected anywhere. For lithium-polymer cells, this value is only 5% per month, which is very low, especially compared to other types of batteries.

A new charging cycle is started by the controllers if it detects a significant level of charge loss. Regularly this element checks the battery for this item. But this process will start only after the loss of at least 2% of energy. And the latter can happen no more than 2 times a month. So, if the user leaves his gadget on charge for 30 days, then the battery will probably go through 2 repeat cycles.

So, what is the right way to approach the issue of charging an iOS device? Probably, many have already understood from the article that there is no single “recipe”. Apple gadgets include a controller to protect the device in critical situations. On the forums, some users note that they have been using smartphones for 3-4 years, charging them haphazardly, that is, at random. Most often, the device charges 100% overnight. But especially active users have to recharge during the daytime. And with this approach, nothing bad happens to the battery. After 4 years of use, it holds a charge well (on average, 1 day - no problem). So you don't have to worry too much about this issue. Start the process whenever you see fit. The most important thing is to use only original accessories from the manufacturer. And this applies not only to charging. Otherwise, you can cause irreparable harm to your gadget.

Chaotic. Usually they do this “on the go”, whenever possible. They often put it on overnight, for more than 7 hours. Let's look at how to properly charge your iPhone.

Despite the fact that charging an iPhone is a simple process, it is still worth considering some details

It is important to charge a newly purchased iPhone correctly, only then will it serve properly for a long time. If you want to know how to properly charge an iPhone, follow the instructions below for the first cycle.

After taking out your new iPhone, connect it to the charger for 3 hours.
After 100 percent, disconnect and use it until the battery is completely drained. Be sure to charge it fully.
When the smartphone turns off, leave it for 2 hours and do not use it.
Next, you need to charge it again to 100%; do not use the device during the process.

Night charging

Let's look at what happens to a smartphone when you connect it to a power adapter. Everyone's process modern gadgets They are controlled by a module built into them - a charging controller. It helps to charge your smartphone in the shortest possible time, and in a reasonable time. It does not allow the battery to recharge. Here it is necessary to take into account that 80% is charged quickly, using the maximum possible current; the remaining 20% at a slow pace, reducing the current to extend battery life.

When the process is completed, the controller turns off the power supply. The battery does not transfer charge while remaining idle, and does not lose it. They say: after 100%, a cyclic charging/discharging mode begins, but this is not true, because then wear would be faster.

It is also known that all batteries are subject to self-discharge when not connected to power sources. Self-discharge rate lithium polymer batteries is 5% per month. The controller checks the remaining stock, when the loss is significant, the process starts again. It resumes at a loss of 2%, i.e. approximately once every two weeks. If you leave the gadget connected to a power source, it will be recharged 1-2 times per month.

Therefore, leaving your phone connected overnight does not cause any harm to it.

Power adapters

All Apple adapters provide a voltage of 5 V, differing in current and power.

A standard power supply of 1 A (ampere), 5 W (watt) fully charges the phone in about an hour and a half.

Let's consider the question: is it allowed to use a power adapter designed for an iPad for an iPhone? The official Apple website claims that the iPad can be charged with an adapter iPod models, iPhone. The power controller regulates how much current the gadget's battery will draw. Therefore, contrary to popular belief, iPad devices do not harm the iPhone.

It is also incorrect to say that charging iPad speeds up the charging process of the smartphone. Only the 6th generation of gadgets has been taught the accelerated process; previous generations do not have this ability.

Adapters made in China

When considering how to charge your iPhone, do not forget to take into account the country of manufacture of the adapter.

Automotive devices

It is also not recommended to use car adapters for iPhone charging. They will not protect the phone from power surges. The power controller will be damaged due to instability of current strength and voltage of automotive electrical networks.

When the phone stops charging even from the original cable, the process takes too long, not completely, which means the power controller is damaged, which is often the fault of car devices.

Long-term storage

When you need to leave your iPhone for a long time, be sure to follow these steps.

Charge the device to 50%. Fully charged battery will cause loss of part of the battery capacity. Completely discharged, it will go into a state of deep discharge.
Definitely

Every owner of a new car is firmly convinced that he knows almost everything about it. After all, having become the owner of such an expensive branded gadget, you want to fully enjoy all its sophisticated features. But such a trivial question: how to properly charge an iPhone may cause slight surprise and even bewilderment for many users. Well, what could be simpler and more understandable than this procedure - insert the charger into the iPhone and connect it to the network. At first glance, there is nothing complicated in this process. Is it possible normal charging harm electronic gadget? But in fact there is great amount various nuances that affect the quality and speed of charging, as well as those responsible for the durability and condition of the battery.

Recharging the iPhone battery

The battery is the heart of any mobile electronic device. And in order for it to last as long as possible, not only from recharging to recharging, but also until its resource is completely exhausted, you need to know how many times and how correctly it is recommended to charge the iPhone. Neglecting all these tips and rules, gadget owners may be faced with the need to change faulty branded batteries too often. Moreover, replace with new ones, and not always good quality, analogues. And I must admit, this is not a cheap pleasure.

One part of users charges their electronic devices almost every day. Others, on the contrary, resort to this procedure only after the battery is completely discharged. One way or another, all gadget owners want only one thing - for their device to always be active and not fail at the most crucial moment. But how to find that golden mean so that the battery lasts a long time, and the user saves himself from the need to constantly recharge it. Experts recommend: in order for the battery to last as long as possible, it should neither be charged to 100% maximum nor discharged to zero. The most optimal charge level is considered to be from 40% to 80%.

The influence of chargers on the battery condition

The correct charging of the iPhone 7 is influenced not only by competent and orderly actions of the user, but also by the quality of the power supply, network adapter and USB cable. Every owner of an Apple gadget should know that to recharge the battery, you need to use only original equipment from the manufacturer. The thing is that branded chargers are equipped with special microcontrollers that monitor the process of receiving current. And if the charging conditions go beyond acceptable limits, for example, the temperature rises, the voltage jumps or the current drops, then the battery simply stops charging.

Each owner charges the device differently: some consider it necessary to make this procedure a daily ritual, regardless of how discharged it is, others, on the contrary, just wait complete discharge battery What to do with premium devices, such as Apple devices, how to properly charge an iPhone?

It may seem surprising to some, but many experts say that charging the device’s battery to the maximum 100% - harmful. Eric Leamer has done a lot of research on this issue; according to his conclusion, battery charging should optimally be between 50% before 80% . According to his experimental data, the charge that reached 100% , is capable of working less than five hundred cycles, and the one that stopped at 70% - over a thousand.

The only thing special is initial charge, so it’s important to figure out how to properly charge your iPhone. It is worth noting that it is necessary to fulfill all the requirements the first time and follow some recommendations from the manufacturers.

How to properly charge iPhone 5s for the first time?

Although new battery, which is included with the gadget, is equipped with a small amount of energy; it should be charged for the first time, and this charging should last about a day (but not less than 12 hours).

To charge a new battery:

Connect the charging cable to the device;
Connect the charger (charger) to the network;
Leave for at least 12 hours.

This - first cycle, after it you need to actively discharge the new battery, required condition- completely, then perform a second cycle, completely similar to the first.

After the second cycle, the discharge-charge procedure is completely repeated. And the more times you repeat it, the longer the phone, provided with the required amount of energy, will work.

Discharge after the first and second cycle occurs in a natural way, however, it is better to speed it up and for this you can, for example, download large files With using Wi-Fi or start a long video.

Two years after actively using the gadget, it is recommended to replace the battery.

When charging the battery, you should not leave it on a windowsill during the day in the sun or in a hot car. This threatens overheating and leakage of liquid from it, and, as a result, failure of the device itself.

There is no ideal scheme, but still adhere to generally accepted rules and manufacturer’s recommendations.

iPhone is an expensive device that, as a rule, we buy for at least 2 years. At the same time, we have hopes that after the planned service life it will still work properly and we will be able to sell it for “good” money.

One of the first questions buyers ask is about the state of the device’s power supply, for example: “How long does the battery last?” This means it makes sense to take care of the proper operation of the iPhone battery now.

As a power source in iPhones, iPads and other portable equipment, Apple company(other manufacturers too) uses lithium-ion batteries that:

Charges faster.
They work longer.
They have a high specific capacity.
Not subject to memory effect.

Under the memory effect battery refers to the reversible loss of capacity that occurs in some types of electric batteries when the recommended charging mode is violated, in particular, when recharging an incompletely discharged battery.

How iPhone owner and iPad with experience (since 2008), I declare with full responsibility that Apple uses high-quality power sources in its products.

1. Do not operate or charge the device in extreme temperatures (-40°C and +50°C).

Apple considers the ideal temperature range to be between 16 and 22°C and does not recommend "using your device in temperatures above 35°C as this may permanently reduce battery capacity." Overheating is critical!

From personal experience: I don’t look at the thermometer when I pick up my iPhone 5s, which I don’t advise you to do either. It is enough that:

The device has not been exposed to direct sunlight.
Do not leave it in the car in hot weather.
Do not charge under your pillow.

3. To charge your iPhone, use an original charger and at least a certified USB cable.

For example, if you increase the charge voltage of a lithium-ion battery by just 4%, it will lose capacity twice as fast from cycle to cycle. To prevent this, special PMIC controllers are built into the original network adapter and directly into the iPhone (in batteries this is the Battery Management System), which ensure that the conditions for recharging the device do not go beyond the permissible limits: temperature, current and voltage.

IN network adapters Without a clan and tribe, the so-called “nonames,” such a controller may not exist. Consequently, the voltage at the output of such an adapter may exceed valid values and can burn out the iPhone's power controller and then damage the battery.

From personal experience: Charge your iPhone from the original ones chargers certified cable and forget about battery problems.

4. Do not completely discharge your iPhone (to 0%).

The lifespan of a lithium-ion battery is usually expressed in terms of the number of full discharge cycles when you use up 100% of the battery's capacity. For high-quality power supplies this is 400-600 cycles. Apple states that the resource iPhone battery is 500 cycles, and iPad, Apple Watch and MacBook - 1000 cycles.

Whenever you completely drain your device, its lifespan shortens. This is due to the depth of the discharge.

It turns out that the more you discharge lithium ion battery, the faster he “dies”. To increase battery life, avoid deep discharging.

For clarity, I will give the dependence of the number of battery discharge cycles on the depth of discharge.

Not many people know that Apple batteries are charged in 2 stages:

Up to 80% - in fast mode.
From 80 to 100% - compensation charging.

This charging system allows, firstly, to quickly charge the device, and, secondly, to extend its service life.

Remember, completely discharging a lithium-ion battery will shorten its service life and reduce its capacity.

From personal experience: Connect iPhone and iPad to a power source at 10-20% charge and disconnect after 80%.

5. Don't charge your iPhone to 100%.

Fully charging a lithium-ion battery is not as scary as deep discharge, but still undesirable. Of course, the controller will not allow your device’s battery to overheat and overcharge, but, as practice shows, constantly plugging in a 100% charged iPhone reduces its battery life.

From personal experience: Leave your iPhone charging overnight. For some time, a 100% charged device will be connected to the network, but nothing will happen to it - not enough storage time to worry about it. With this charge, your iPhone will last for more than two years.

It is difficult to control the chemical processes occurring in the battery. And since the dependence of the output voltage on the battery capacity is nonlinear and the lithium-ion battery is subject to natural aging, accompanied by a decrease in capacity, and also because we charge devices haphazardly, over time, the iPhone’s power controller cannot accurately determine the battery charge level. Diagnosis: iPhone turns off even when charged more than 1%.

In order to calibrate the controller and bring the charge level indicator to life, the iPhone needs to be completely discharged. Apple advises doing this no more than once a month.

Conclusion

In conclusion, I would like to note that each of us charges our devices in our own way. If there is ideal scheme, then it cannot satisfy everyone, since we live in different rhythms and in different conditions. Remember, your iPhone battery will age even if you do not use the device. Follow the rules described above (you don’t have to follow them strictly) and even if your iPhone battery fails, it can always be replaced.
