Charges up to 3 percent. Close and delete applications

Hello! iPhone charging and problems associated with it are perhaps the biggest “misfortune” that awaits owners of Apple devices. Well... after forgotten password from iCloud - that's for sure. The website already has a lot of instructions telling you how to charge correctly, what you can do while charging and what you can’t do, etc. But still, new problems keep popping up!

IN Lately it just appeared great amount comments with the same problem. Users write that they cannot fully charge their iPhone. He doesn’t want to (or can’t?) - that’s all! Moreover, first charging in progress as expected, but then it reaches a certain percentage and everything stops. It's like some kind of epidemic! Let's figure out what is the reason for this behavior? Go!

What could be causing this? In fact, there are only two options:

• Problems in the software (the operating system).
• Problems with hardware (the Phone is not always to blame).

Let's start with the simplest...

iPhone is not charging fully - iOS system glitch

Nothing is perfect and the iOS operating system is no exception. It may be the reason why the iPhone is not fully charged.

Typical behavior for this case is when the charging percentage reaches 98-99 and freezes for a long time. It turns out that it’s almost charged, but it’s just a little short of reaching the cherished 100%.

What can and should be done here? Here are some solutions:

Important! Everything listed above is worth trying in any case, even if the charging percentage freezes at lower values ​​- it can help. But if it doesn't help, then...

iPhone charging does not reach 100% - hardware problems

Failure of an iPhone to charge above certain values ​​may be associated with other, more serious faults.

Especially when the charge reaches half or a little more and stops - that is, there is quite a lot “missing”.

There can be two main ones:

As you can see, there are many reasons why the iPhone does not receive a full charge.

And, unfortunately, among them there are some very unpleasant ones. For my part, I can only wish that you fix the iPhone battery without resorting to serious actions - assembling and disassembling the device, replacing spare parts, contacting service center etc. Let everything be resolved in much simpler ways!

P.S. In order to increase the likelihood of a successful outcome, put “like” and click on the social network buttons!

P.S.S. Do you have any questions or questions? Tell us in the comments - let's try to figure it out together!

Every user may encounter the problem when the iPhone is not fully charged. If we're talking about about a smartphone that has been in use for more than a year, the cause of this problem may be a natural loss of battery capacity. In this case the only way out will replace the battery.

But if a brand new iPhone does not fully charge, this may mean a failure of the operating system or a malfunction of the power adapter, Lighting cable, rupture of the cable, or breakdown of other parts of the Apple gadget.

iPhone won't charge due to operating system glitch

If your iPhone doesn't charge completely, the problem may be due to an operating failure. iOS systems. Characteristic signs are that the phone is charged up to 80-90 percent and no more. It turns out that the iPhone does not charge to 100 percent just a little bit and you can fix this as follows:

– try rebooting the device by pressing and holding at the same time Home buttons and inclusion

battery calibration– completely discharge your smartphone and charge it to 100 percent iPhone charging

installing an application to monitor battery consumption– download in App Store special program, which will allow you to control battery discharge in any mode

flashing– install new firmware on iPhone and run OS recovery

If, after the above procedures, more than a percent of the iPhone still does not charge, then you need to consider other causes of the breakdown and try to eliminate them.

Incomplete charge of the smartphone due to faulty parts and components

Often, incomplete charging of the iPhone is the result of serious malfunctions of parts and components. A characteristic sign of hardware failure is that the iPhone's charging percentage reaches 50 or 60, after which the process stops, while the battery indicator continues to blink. The main reasons for this are as follows:

• malfunction of the power adapter - physical wear, oxidation of contacts or bending of the charger wires leads to incorrect charging of the iP. The way out of this situation is to purchase a new pair of adapter and cable
• Battery failure – due to natural wear and tear of the battery, the smartphone gradually stops being fully charged. This can be corrected by replacing the power supply
• Damage to the cable - if the gadget does not fully charge due to bending or disconnection of the cables, the smartphone can only be repaired by replacing them with new ones

You can determine what exactly is causing the iPhone to not fully charge only after full diagnostics gadget. If you find it difficult to identify a malfunction and are not sure that you can cope with the repair yourself, seek help from experienced specialists.

Natural loss of battery capacity

In progress iPhone operation Natural loss of battery capacity is inevitable. According to official data, after five hundred full cycles After recharging, the battery power is reduced by 20 percent of the charge. However, there are factors that contribute to premature loss of battery capacity. The main ones are the following:

• temperature violation when charging the device
• non-compliance with recommendations regarding discharge depth
• using a non-original charger

If you charge your iPhone correctly, the problem of loss of battery capacity and charge can be delayed for at least two years.

The influence of discharge depth on the battery charging cycle

Experts do not recommend completely discharging the battery of smartphones, as this negatively affects the battery capacity. When a smartphone is completely discharged, its service life is reduced. There is the following dependence of the charging cycle on the depth of battery discharge:

• If you completely discharge the device, the number of charge cycles will be 500
• when the battery is discharged by 50%, it will withstand 1500 charging cycles without loss of capacity
• when the battery is discharged by 25%, the number of charging cycles will be 2500
• if you charge the battery at 1, 2, 3, 4, 5 and 20 percent charge, the number of cycles will increase to 4500

That is, the less often you completely discharge your iPhone, the longer it will last you.

Using a non-original charger

If your iPhone won't charge completely, it may be due to a non-original charger. Experts recommend charging Apple gadgets exclusively with the original Lighting cable, since it is equipped with a special chip responsible for authenticating the smartphone. If the Apple device does not see this chip, it simply does not accept the charging cable. Consequences of use non-original charging may be as follows:

• cable damage
• deformation of the charger connector
• Battery swelling
• failure motherboard

While charging Apple smartphone cable made in China you risk “killing” him completely. Poor-quality chargers cannot protect the device from sudden changes in voltage in the electrical network, so the probability of its premature failure is 90 percent.

If you decide to put your smartphone away for long-term storage, then you need to do it correctly. With a deep discharge, there is a risk of premature loss of battery capacity, which affects the life of the device itself. Recommendations for storing iPhone are as follows:

• charge your phone to 40-50 percent - storing your phone with fully charged battery negatively affects its functionality
• turn off your smartphone - if you put the gadget away for storage while it is turned on, the battery is likely to be deeply discharged
• observe temperature regime– recommended storage temperature 25-30 degrees Celsius

If the shelf life mobile device exceeds six months, it must be regularly recharged by at least 50 percent. If you follow these recommendations, the functionality of your smartphone will remain after several years of storage.

Battery drains quickly

Another common problem with Apple gadgets is fast discharge batteries. If the battery is charged to 100 percent capacity, but then completely discharges within a few hours, the following may be the cause:

• firmware failure
• automatic mail update
• automatic software update
• cable damage
• simultaneous launch of several applications
• incorrect device settings
• active location services

The mobile device can be recharged from an electrical outlet, but cannot be charged from a computer. In this case, you need to completely discharge the battery and charge it again, or do forced reboot. If this does not help, contact experienced repair technicians for help. Apple gadgets, registered to Yuda.

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:

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.

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:

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 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:

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. 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.

Don’t rush to get too upset, this problem is solved in 95% of cases, I have encountered it myself. In this article I will tell you what actions can and should be taken to understand the cause of this malfunction and how to deal with it. There can actually be many reasons why the iPhone 6 and 6 Plus does not charge, because it is a complex device. Let's see what options we have:

• Software failure;
• Malfunction of the cable or charger (plug, or charger - charger);
• The charging connector is broken;
• iPhone motherboard is faulty.

We will start with harmless problems that can be easily solved at home without a visit to a service center.

iPhone 6 and 6 Plus do not charge well due to a firmware glitch.

In fact, this happens very rarely, but what the hell, as they say. Try rebooting your phone. To restart your iPhone 6 and 6 Plus, you need to hold down the Power button and the Home button until the phone turns off and the boot apple appears. This may take up to 25 seconds. If it helps, great! And if charging still does not proceed, move on to the next point.

iPhone 6 and 6 Plus won't charge or won't turn on due to cable or charger.

iPhone 6 and 6 Plus may not charge due to faulty cable or memory. I think this doesn’t surprise you :) Therefore, if rebooting doesn’t help, then try some magic with the cable or charger.

First, make sure the outlet is working properly. If you are using an extension cord or pilot, check that the power button is in the “ON” position. Sometimes the iPhone does not charge from the charger for this very reason.
When did Apple switch to new Lightning cables(Lightning) the whole world was outraged, but accepted the new connector. However, not everyone knows that this cable has literally become smart! It has a built-in chip that is responsible for recognizing the originality of the cable when connected to the phone. Cheap cables use non-original chips, which can cause an error when recognizing the cable and, if they fail, they can, at best, stop charging the phone, and at worst, damage the power controller of the iPhone 6.

Therefore, if the iPhone does not charge from the cable, try using another one; perhaps the phone simply does not see the charging. A faulty Lightning usually displays a message something like this: “this accessory or the cable is not certified". The charger plug itself is not as smart as the cable, but it can also fail.

It is also worth knowing that from iPhone computer 6 and 6 Plus may also not charge. This is due to the fact that for correct charging the current must be 1 Ampere, but not all computers can output so much per USB port, most often it will be 0.5. For the same reason, if you charge your iPhone using a cheap Chinese plug that gives out 0.5 Ampere, then most likely the iPhone 6 and 6 Plus will not charge, and sometimes even slowly discharge.
It is better to use original accessories, it is not cheap, but it is safe.

Charging connector for iPhone 6 and 6 Plus.

Quite often the charging connector fails. It accounts for about 70% of calls to the service. A typical symptom of a faulty connector is that the power connection indication constantly “jumps”, that is, the cable seems to be connected and immediately disconnected, or the charge only occurs in a certain position of the plug.

The cause of iPhone 6 and 6 Plus connector failure is usually either moisture or broken connector contacts. In the first case iPhone won't charge due to the fact that the contacts are oxidized, and in the second due to a sunken or broken contact. The replacement procedure is standard; the connector is replaced as an assembly with the lower cable. It also contains a microphone, speaker contacts, an audio jack and a GSM antenna; this part is not dismountable. iPhone repair takes about 20 minutes including testing.

iPhone 6 and 6 Plus stopped charging due to battery.

This also happens often. In this case, the standard symptom is the lightning indicator next to the battery, but the battery is not charging. Another sign faulty battery– the eternal download apple. The apple lights up on the phone, stays on for a while and goes out, then after a couple of seconds it lights up again. Common reason The malfunction is trivial - battery wear. In this case, there is no need to worry; everyone faces this sooner or later.

If the iPhone 6 and 6 Plus does not charge after replacing the battery, then try to claim warranty; most likely the battery is defective. You can find out more about this problem in the article replacing the battery. By the way, when I said that I also encountered a charging problem, in my case it was the battery that was to blame. Which is generally not surprising, he lived for almost 3 years.

iPhone 6 and 6 Plus discharge and charge quickly or slowly and get very hot.

Here we come to the most serious possible problem– motherboard malfunction. Due to falls or the use of a non-original cable or charging, the charging controller (U2 Tristar) or the main power controller may fail. The symptoms are as follows:

• iPhone 6 and 6 Plus are completely discharged and will not charge;
• In standby mode, the phone discharges quickly;
• iPhone 6 and 6 Plus only charge when turned off;
• iPhone charges very slowly;
• The phone gets very hot when charging.

Despite the fact that this breakdown is quite serious, we can fix it without any problems. Repairs can take from several hours to several days, depending on the complexity of the situation. You can read more about such repairs in the article Replacing the power controller for iPhone 6 and 6 Plus.

Summary.

So we hope we figured out why the iPhone won’t charge and what to do in this case. If this article helped you, I’m glad, my task is completed. If you have any questions or require repairs, call, write or come, we will definitely help you!

Smartphones have become life companions; not a single task can be solved without the help of these electronic assistants. Calls, internet, useful applications, everything is on them. Sometimes it happens that the battery life of a device begins to rapidly decrease. Turning from 20 hours to 9, then to 3, and finally, the iPhone charges only when it is turned off. Why this happens and what to do to return the device to combat readiness, we will tell you in this article. Let's start with the methods that you can do yourself at home; if that doesn't help, then a master from the nearest service center will help.

How can you determine whether your iPhone is charging when it is turned off? This is easy to do; if you see a picture like this, it means energy is reaching the device board, but it does not mean that the battery is being charged.

If you see a picture like this, most likely there is something wrong with the charger, cable or lightning connector.

Below we will look at what steps to take and how to revive the gadget at minimal cost. Let's get started.

Checking the memory

To begin with, if the iPhone charges only up to 4-20 percent when turned off, it’s worth checking charger on another device. It is quite possible that:

• The wiring in the cable is interrupted - the current strength in this case is significantly reduced, preventing the battery from being charged to the required 100%.
• The electronics in the charger unit have burned out, again, the current strength will be significantly reduced. Repair is powerless here; it’s better to immediately buy a new charger for iPhone 6.
• The lightning plug is loose or the chip on the cable is damaged (yes, yes, there are chips in iPhone laces).

It’s quite simple to check whether the charger is working; we take a working charger from friends/neighbors/lovers and connect it to our unfortunate device. The iPhone beeped joyfully, notifying that energy had entered the battery, then we run to get a new, preferably original, charger.

You can also buy Chinese ones, but not the cheapest ones; chances are you will end up with quality products. But it remains large percentage that you will get a counterfeit product that costs a lot of money and is not capable of fully charging the gadget’s battery. Among other things, counterfeits can damage the device’s power controller, and this is 100% dependent on the services of service centers.

Cleaning the connector

You can try cleaning the connector; it often causes the iPhone to boot up and only work when charging. To do this, take an ordinary cotton swab and carefully, without fanaticism, clean the connection point of the lightning plug.

Inspecting the cable

Now let's take a closer look at the cable itself. There should be no creases or kinks on it; if there are any, we try to change the wire, borrowing it from a neighbor. in 80% of cases it is the culprit, if so, feel free to throw the cord in the trash, repair is not advisable, even if it is an original accessory that came with the phone.

The screen says "accessory is not supported or certified"

1. Try reconnecting the cord with the other side, sometimes it works.
2. The wire is broken or broken.
3. You neglected the advice to clean the connector.
4. Yours is cheap Chinese fake, throw it away and go to the store again.

Close and delete applications

After several years of work for the benefit of the user, the smartphone battery may no longer provide the required amount of energy. Then a situation arises: iPhone 5, 5s, 6, 6 plus can only be charged when turned off. Before opening the case of the device, let's try to turn it on while charging, even if the iPhone does not charge when turned on. In this mode, we will close and remove “energy eaters” - applications that consume energy in background. Let's reboot the device and see the reaction.

If it helps, great, you’ll have to replace the battery; if it doesn’t help, no problem, read on in the article. But in any case, you end up with, at a minimum, a replacement battery, at worst, a replacement of the power controller and everything that will require a repairman to replace it.

Reset iPhone to factory settings and update iOS

This measure will allow you to restore functionality in 20% of cases, most likely the problem is something else, but as a measure before replacing the battery, it’s worth trying, at least make sure 100% that this is the problem.

How to properly reset to factory settings, read in this article; how to update, read here.

Why can my iPhone only charge when it's turned off? This question remains to be asked to the moderating battery; this will be the final and saddest part of the article. Sad because you will have to leave the house and spend money on smartphone repair specialists.

We reanimate the battery

Battery problems are familiar to all owners. cell phones, iOS or Android, it doesn't matter. Over time, the battery material begins to “deteriorate”; the more charge-discharge cycles, the less the electrical capacity becomes and the faster the smartphone runs out. Usually the “death” of the battery occurs after 3-4 years of operation, the number of cycles exceeds 500-700 and problems begin. One of them is that the iPhone can only charge when turned off. Now, in order, what is worth checking and where to put your hands.

Having checked the charger and the accessories adjacent to it, perhaps even replacing them with new ones, removing everything that was not required applications and generally turning off the smartphone, but still, the iPhone charges only when it is turned off, then we move on to a more complex stage.

The ideal option would be to purchase a new battery and install it to replace the damaged one (I will attach a video on how to replace it), but this is not always realistic due to circumstances and the user’s lack of repair experience.

The only option is to leave the unfortunate iPhone turned on all night; this is unlikely to help restore the device and the battery in it, but it’s worth a try.

Non-removable resuscitation iPhone batteries It is advisable to practice not at home, but even better, it will be left to be torn to pieces by experienced people who know a lot about safety and quality repairs mobile phones.

Conclusion

To summarize, I can say that if the first sections of this article did not help you, then you will not be able to independently find the answer to the question of why the iPhone charges only when it is turned off. I recommend contacting a service center, where they will help you revive your electronic friend for a reasonable price. Your intervention will most likely lead to an increase in the cost of repairs. Be careful and attentive, and everything will work out.
