Do I need to discharge a completely new iPhone 7. Benefits of using wireless charging

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 tasks should be removed from the list running applications 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 promptly software, since 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 higher temperatures may cause permanent battery damage. 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 now offers the ability to find out which applications are the most draining of battery power. If desired, the user can limit the background activity of the most "gluttonous" programs.

Articles and Lifehacks

Information regarding charging rules is of interest to many users who want their smartphone battery to last as long as possible. This is especially true for all new owners who do not know how to charge iPhone correctly. Of no less interest is the question of how, after all, too quiet sound makes using the device uncomfortable.

The list of topics that interest them is very diverse. What is the best way to charge a smartphone with frequent use? How many mandatory charging cycles are required after purchase? Let's look at the answers to them in more detail.

iPhone battery and main rules for charging it

On this moment iOS devices have built-in lithium-ion polymer batteries.

It is worth noting that lithium is not only the lightest metal (which ensures less weight of the device), but also, together with other battery materials, provides a longer operating time. Such batteries can be charged at any time, unlike nickel ones, with which you must wait until they are completely discharged.

However, after iPhone purchases It is highly recommended to completely discharge and charge the device 2 times in a row. This charging time is at least 4 hours.

As a rule, it is in the first hours of charging such batteries that up to 80% of their capacity is replenished, and then recharging with a weak current continues. The very first stage takes 2 hours, and the next one – another 2 (provided that mobile device will not be used while charging).

Complete battery discharge-charge cycle with frequent iPhone operation It is useful to carry out about 1 time per month.

So, how to properly charge your iPhone? There are some basic guidelines on this topic.

Thus, he has the power to disable the delivery of notifications from App Store and active delivery Email, download new data less frequently and use location search services (the “Geolocation” item in the main settings). All this will allow the battery to work without recharging much longer.

Other tips: turn off Wi-Fi (3G, Bluetooth), turn down the brightness, turn off the equalizer and backlight, and use third-party apps less often.

In addition, you can save battery power by disabling the music and social network from Apple called Ping (available starting from firmware version 4.3). To do this, you need to go to the main settings, select the “Restrictions” item, enter the password, then find the Ping item and disable it.
In order for the device’s battery to last longer, it is not recommended to leave it in the open sun or inside a heated car (even in a case), or expose it to low temperatures.

Correctly charging iPhone: brief instructions

In the box along with the smartphone you can find the components that you will need to charge the device. In particular, this is the network adapter and USB cable.

If the smartphone was brought from the USA, the network adapter may have a flat plug. In this case, for a small amount you can purchase a special adapter for a European socket. Instead, you can use charging from a computer via a USB cable, although this is not always convenient.

In addition, the user can also buy a European network adapter - although it will cost him a little more.

Now a little about the charging itself. It is strongly recommended to use branded accessories, but in no case pirated products. You can charge your iPhone either from a computer or from the network via an adapter.

Ideal scheme does not exist, but still adhere to the generally accepted rules and recommendations of the manufacturer.

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 others portable equipment, Apple company(other manufacturers too) uses lithium ion batteries, which:

1. Charges faster.
2. They work longer.
3. They have a high specific capacity.
4. 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.

As an experienced iPhone and iPad owner (since 2008), I declare with full responsibility that Apple uses high-quality power supplies 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:

1. The device has not been exposed to direct sunlight.
2. Do not leave it in the car in hot weather.
3. 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 using original 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 a lithium-ion battery, the faster it “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:

1. Up to 80% - in fast mode.
2. 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. Even if there is an ideal scheme, 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.

I absolutely welcome you! The question (voiced in the title of the article) is, on the one hand, quite interesting and thought-provoking, but on the other... What is there to think about? After all, in essence, the answer will be very simple - you insert Charger and charge! How can this be done wrong?

It would seem that we could end there, however... there is great amount related nuances regarding the correct iPhone charging. How to charge without damaging the battery? What is possible and what is not? What to do after purchase - wait for the discharge or use it immediately? Now we will figure it all out! But first, let's remember one very simple truth- The battery must not be charged incorrectly. What a surprise! :)

This is simply not possible due to the fact that:

• Wire.
• iPhone.
• Power supply.

There are special controllers responsible for the process of receiving current. If one of them doesn’t like something, the device simply won’t charge. Of course, it is necessary to stipulate that we're talking about about original accessories. In “Chinese” ones for 100 rubles there can be no talk of any microcontrollers. And although they are not originals, it is better not to use them for a long time, but only in desperate situations.

The only thing that can be done correctly or incorrectly while charging is not to cover the device with a blanket, pillow or other materials. Because the iPhone, and most other gadgets on the market, tend to heat up while charging (). And it’s safer when this heat escapes freely into the atmosphere.

How to charge an iPhone for the first time after purchase?

As you wish. Devices go on sale already with a certain charge level, so it can be used almost immediately and without any restrictions.

If we talk about the fact that for the first time, before using it, you first need to completely discharge the device, then fully charge it, and “that’s all about it.” Here it should be noted that modern lithium-ion batteries do not have the so-called “memory effect”, so there is no need for all these procedures. Plus, their service life, as a rule, is about 500 such cycles - and this, for a second, is 2 years. And only after that they will begin to more or less seriously lose capacity.

The conclusion is this: we bought it and use it freely.

How long does it take to charge an iPhone?

The correct answer is as much as he needs. Moreover, the speed at which the battery will be filled with energy depends on many conditions:

• The choice of power supply unit is important. By the way, I safely use the adapter from the iPad () - it turns out really faster.
• Whether the device is being used while charging or not. It’s clear that if you play a game and charge at the same time, the process may take longer.
• Even the length of the wire matters!

If we talk about charging time from 0 to 100%, then for an iPhone (depending on the model) it may take from 1.5 to 3 hours. Naturally, the “plus” iPhone 6 and 6S take the longest to charge. Simply due to the fact that they have a more capacious battery. This is more of a guideline; yours may be a little more or less. about the charging time of each model and whether you need to pay much attention to it?

In cases where deviations from this “norm” are large enough, read this article again. You may be doing something wrong. Although problems with the battery cannot be ruled out, there are no service center not enough.

Finally, a few more useful tips, which are published by Apple for correct charging and preserving battery capacity:

1. Apple recommends removing cases while charging, as they cause heat, which in turn negatively affects battery capacity.
2. For the same reason, you should not use the device in the cold.
3. If you want to put your iPhone in temporary storage, it’s better to charge it halfway, turn it off, and then safely put it away for a long time.
4. Only original accessories. Yes, it is important. By the way, it is not necessary to use cables and power supplies from Apple; it is enough that they are simply certified. You can identify them by the inscription MFI (Made For iPhone) on the box.

In general, it should be noted that all of them, except the last point, are purely advisory in nature.

Every iPhone owner asks the question: how to properly charge the device and at the same time ensure long battery life. In this article, we have collected tips and tricks that will help you learn more about this.

Due to improper use of the smartphone, the user may unknowingly shorten the battery life. This happens every day, and in order to correct the situation, it is worth familiarizing yourself with the unspoken rules for extending battery life. Let's consider what negatively affects its work.

Extreme temperatures

Any gadget, be it a phone, tablet or computer, is sensitive to both too low and too low high temperatures. This is justified by the absence of a heating or cooling function for the device in the internal configuration. Consequently, the “filling” of the iPhone may simply freeze or heat up and fail, or in the worst case, catch fire.

• the screen was not exposed to direct sunlight;
• the smartphone was not in a closed, stuffy or hot room (for example, in a car in the heat);
• did not charge in places where there is no ventilation, no access to air, because The device will not cool down.

Rule #1: Do not use or charge your device in extreme temperatures.

Non-original charger

The standard iPhone power adapter has a voltage of 5 volts (V) and a current of 1 amp (A). Complete with a certified cable, the phone charges in an hour and a half. If the equipment turns out to be non-original, both the battery and the phone may suffer.

It's all about the manufacturers - some provide quality products, others may give the user incorrect information about the characteristics, i.e. indicate the standard 5V and 1A, and sell the product with values ​​that will be greater or less than those indicated.

Even with a slight increase in voltage, for example, by 4%, the battery capacity will decrease twice as fast from cycle to cycle. Typically, the differences are regulated by the built-in PCIM controller, which is responsible for supplying current.

Counterfeits may not have such a controller, which can result in high output voltage. This can damage both the charge controller in the iPhone and the battery itself. It is better to protect yourself from problems and use the equipment provided by the manufacturer.

Rule #2: Use the original adapter.

Chinese charging cable

Business with Lightning cables things are more complicated. Many iPhone owners have heard that such cables break easily and are not cheap. Its plug is equipped with a special chip with which the iPhone recognizes its original wire. Finding such an analogue is quite difficult.

However, the Chinese were able to clone this chip, selling similar cables for pennies, which is how they lure users. It is worth assuring that such a product may work, but for a very short time. We recommend using cables that have passed Apple certification - this way you will avoid additional damage to the device.

Rule #3: Buy only certified cables.

Full discharge

Used in smartphone lithium ion battery, and it is very sensitive to the charge dropping to zero. This can cause significant damage, resulting in a reduced service life. This is all due to the depth of discharge - the ratio of the discharged capacity to the nominal one.

For example, if you use up 100% of the charge and do this constantly, the battery in this state can withstand about 500 cycles. If the phone is only half discharged, the number of cycles instantly increases to 1500. It turns out that the more you discharge the battery, the less it will last you.

Rule #4: Don't completely drain your iPhone.

Charge up to 100%

When the device's charge reaches maximum, the battery is in high load. This is due to the fact that each cell of a lithium-ion battery is charged to the required voltage, therefore, the higher the charge, the shorter the lifespan of one battery cell.

Of course, this does not cause as much harm as completely discharging it, but it is better to charge the iPhone in small portions - at every opportunity, even by 10-20%, but often and painlessly. The optimal charge level is considered to be 40-80%, so you can charge the phone starting from 50% and ending with no more than 90%.

Rule #5: Charge your device more often.

No battery calibration

When using the phone for a long time, the charge indicator inevitably goes down. This is due to improper use, frequent discharge, incorrect operation of the smartphone itself (sudden shutdowns, damage internal components, etc.), or charging the battery at random. Full discharge is appropriate if the iPhone displays an incorrect charge indicator. Then it’s worth bringing the phone first to 100%, and then to zero, or vice versa.

This process is called "calibration". Sometimes you have to do it in order to bring the battery back to life. For prevention, it is best to do this procedure no more than once a month.

Rule #6: Periodically discharge your iPhone.

Is it possible to leave an iPhone on charge all night?

Many people are debating whether it is safe to charge an Apple smartphone overnight. Therefore, we conducted our own investigation. In fact, long-term charging at a constant value of 100% does not cause much harm to the battery. When your iPhone is fully charged and connected to a charger, it runs on AC power. At this time, the smartphone is not charging or discharging, and the battery is in a “feeding” state.

If the charge drops by 2% during overnight charging, current begins to flow through the cable. This does not cause much harm to the battery, because this happens infrequently - about once a week. In other cases, the current is kept at a stable level, therefore, the device does not “fry” at night.

Is it possible to charge an iPhone using an iPad charger?

It’s worth answering right away: yes, you can. This is possible thanks to the built-in iPhone special branded charge controller. With it, the charging speed is deliberately reduced after 80% in order to control the optimal current supply. He is also responsible for “working from the network” and constantly monitors the health of the battery. For this reason, when charging from the iPad adapter, the battery is not loaded, despite the fact that it has a voltage of 5 volts and a current of 2.1 amperes.

Total power iPad charging is twice as much as the iPhone adapter. It is logical to assume that in this case the smartphone will charge faster, but this is not true. IN old iPhones, regardless of the current supply level, the built-in controller does not allow you to receive more charge than what is written in it. In new models, starting from the sixth generation, the manufacturer was able to speed up the process a little, but only slightly.

Long term storage

During long-term storage, the device may wear out considerably - some functions will become worse, the battery will lose its capacity, etc. To prevent this from happening, you must follow the following recommendations:

• Charge your iPhone up to 50%;
• turn off the device completely;
• store in a dry place where the temperature does not reach +32 degrees;
• update every six months charge iPhone up to 50%.

The device should be charged with half the battery capacity, because full charge can significantly reduce service life. The same applies to his absence. At 100% the primary capacity is lost, at 0% the phone goes into deep relaxation, and this harms the battery.

The company has prepared relevant recommendations especially for its customers, which are especially worth listening to:

• You should not charge your iPhone together with the case, because... this may cause the phone to heat up;
• the same can be said about using a smartphone in cold weather;
• should only be used certified accessories marked MFI (Made for iPhone) on the supplied box or on the product itself;
• Before long-term storage, charge the phone halfway and turn it off.

It is worth noting that Apple only recommends, and does not tell users how to handle the company’s devices. According to iPhone owners, it is not necessary to strictly follow all the rules for using the battery. The manufacturer has created special built-in controllers so that the owner does not damage the battery through his actions. However, the tips described above will somehow help extend its life for many years.

Video instruction

You can see detailed video instructions about how to properly charge your iPhone. The created video will help users better understand the implementation of all the provided actions.

Results

Usually we don’t monitor how we use the battery and don’t notice how much harm we cause it. However, you shouldn’t worry too much about this and constantly worry when the gadget turns off on its own initiative or due to the user’s inattention. Apple carefully monitors the quality of its products.

Therefore, even with normal use, the battery will function as before for the standard three to four years. There is no perfect plan for how to increase battery life. Just don't overuse the capacity, always keep an eye on the charge and beware of extreme temperatures.
