The iPhone charges to 3 percent and turns off. Incomplete charge of the smartphone due to faulty parts and components

To always stay connected, do not forget to charge your smartphone in a timely manner. Unfortunately, sometimes the mobile device does not respond at all when connected to a power source. If your iPhone is not charging, then the problem can most often be solved simple actions. We also figured out why sometimes the iPhone does not charge from Power Bank.

1. Plug the cable into the gadget.
2. Insert the second end of the cable into:
   • USB socket adapter.
   • Into the USB port of the computer.
   • Certified Accessory: Externally powered docking station or hub.

After this, you should see a large image of the battery on the screen (in lock mode) or a lightning bolt in the status bar.

If your smartphone does not respond to charging - there is no lightning icon - or shows charging, but is not charging, first check the most simple reasons problems:

1. If the phone is completely discharged and turns off, and then does not turn on or charge, leave it on charge for 10 minutes. If there is a severe loss of charge, the screen may remain black for the first time, without indicating the process.
2. Inspect and feel the cable for kinks, breaks and bent contacts. Use only certified wires. If you suspect cable damage, try connecting iPhone 4 with another one.
3. Inspect the port on your smartphone, especially if you carry an iPhone 7 or 6s with a Lightning connector without a closed case in your pocket. Dust is easily forgotten in the port, short contact pad The Lightning cable no longer fits tightly, and therefore the iPhone 6, 6S, 4 or other model does not charge. The solution to the problem is simple - take a clean toothpick and carefully remove the dust and lint. Additionally, blow the port with air and connect it to a power source.
4. If iPhone 5, 6s or another model does not charge from a computer via USB, switch the wire to a different connector. Some USB ports may simply not work due to their breakdown or incorrect connection, so the PC does not see the attached gadget and does not respond to it.

If after all the checks the iPhone 5, 5S still does not charge, we look further for reasons.

"The accessory is not certified"

In the fight against counterfeits, Apple engineers have taught their products to recognize the authenticity of cables. To do this, the plug is equipped with a special chip that tells the phone which wire it is going to be plugged into the socket. If the iPhone stops charging completely and displays a message about connecting an uncertified accessory, change the cable to an original one.

If such a message appears when using the “original” wire, check its integrity and clean it iPhone port and reboot your device.

Software problems

Another common reason why it won’t charge is failures software. If errors occur in the operation of iOS, a command is not sent to the controller and charging does not occur. The problem is resolved by forcing a reboot:

• On iPhone 7 and higher: hold down the power and volume down keys for 10-15 seconds until the Apple logo appears on the display.
• On iPhone 6s, 5 s and younger: hold down the power and “Home” keys.

And it will turn on, after which it will begin to respond to charging.

When to go to service...

Some problems cannot be resolved on your own. If the power controller breaks down due to impact or water, or the battery life has expired, you will have to contact service. Signs of internal damage - the phone does not charge and does not turn on, quickly loses charge, gets very hot, or the iPhone shows that it is charging, but the charge does not increase.

If you've been using your iPhone for more than a year, its battery will start to drain faster and faster. Over time, the intervals between recharges can be significantly reduced - replacing the battery will solve the problem. Please note that on a smartphone non-removable battery, so entrust its replacement to the service center. You can remove the battery yourself only if you can properly disassemble and reassemble the gadget.

Charging from Power Bank

There may be several reasons why an iPhone does not charge from a Power Bank. First, check that the cable is working properly and connect another device to charge. If everything is fine with the wire, and the Power Bank does not charge the iPhone 5s, 6 or another, investigate:

• Output current: iPhone requires 1 A.
• Use original Apple wires, and not complete ones from the Power Bank - too thin a section reduces the voltage and current.
• Capacity ratio external battery and phone: for successful full charging, the battery capacity of the gadget must be 2 times less. IN regular iPhones 1700-1900 mAh batteries are installed, in Plus line– 2800-3000 mAh. For Chinese Power banks, the actual power may not correspond to the declared one.

If all the parameters are in order, but when connected, the Apple gadget does not charge, although the charge of other devices on this Power bank increases regularly, the device is not compatible with your smartphone.

If the charging process is progressing, but extremely slowly:

• Unload applications from your smartphone memory - double-click on “Home” and swipe up unnecessary programs. Skype, instant messengers, games, browser with open tabs– all of them constantly waste the device’s energy. To speed things up, you can turn off your phone altogether.
• Calibrate the batteries of the Power bank and smartphone - you need to completely discharge them 2-3 times before turning off the device, after turning them on, leave them to charge to 100%. This will help adjust the power controller and avoid accelerated discharge or sudden shutdown.

Conclusion

We figured out what to do if your iPhone won’t charge from a charger or Power bank. Most causes can be eliminated by the simplest actions - cleaning the port, changing the cable, rebooting the phone. If the phone dies and refuses to turn on after all the manipulations, take it to the service center, where specialists can see and fix the problem.

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 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 Apple switched to new Lightning cables, the whole world was indignant, 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– malfunction motherboard. 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!

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 others 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 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.

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 iPhone battery without resorting to serious actions - assembling and disassembling the device, replacing spare parts, contacting a 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, then the cause of this problem may be natural loss 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:

• 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 charging cable. Consequences of use non-original charging may be as follows:

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

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’s on, it’s likely deep discharge battery
• 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.
