Rechargeable battery is one of the weakest places of the modern smartphone. The need to "pull" on itself a large bright high-quality screen and a productive processor leads not only to a small time autonomous work The current flagships, to which, however, are all already accustomed to, but also rapid wear.

The battery signals in different ways about the ambulance "death" - one of the signs - an iPhone turns off at a large charge level - 20, 30 and more percent. However, this behavior of a smartphone may also testify other problems. In this article, we will tell you what kind of problems is and how the user should behave in this situation.

Good news! The fact that the iPhone turns off when high level The charge can talk about such a trifling case as a program crash, and in this situation the problem is solved very simply. When the next time the device suddenly turns off - turn it on (clicking on Power or connected in charging - it does not matter), and then reboot.

For reset - hold Home. (In the iPhone 7, this key has become touch, so instead you need to press the volume button) and Power (before iPhone 5S inclusive it is located on the upper face, in later versions of i-smartphones - on the right) and hold before the appearance of a "apple" .

Restore iPhone.

Did not help the reboot? Get upset yet anyway early! To finally make sure that the problem is in the problem of hardware, not a software character, it is required to recover the smartphone. In the process of this procedure, all content and settings and smartphones are removed, and then "get" from backup.

The order of recovery of the iPhone is as follows - first create a backup, then we reset the settings that the completion step - transfer data from the backup back to the device.

Bacup

To make a backup, you can use iTunes or iCloud - in the first case the backup will be stored on the PC, in the second - in the "cloud".

To create a backup via iTunes:

The backup of information in the "cloud" is even easier:

It is worth noting that the backup via iCloud is convenient because it is not required to connect the device with a PC, but it must be connected to high-quality Wi-Fi network. In addition, in the cloud, the user has the right to store only 5 GB of information. Through iTunes, you make a copy of the information on a personal computer, so in this case no one limits you.

Reset

In order to erase the iPhone, there are integer three ways - the procedure can be performed through the smartphone itself, as well as, again, with using iTunes. or icloud.

Reset through the smartphone is performed the easiest:

However, if you made a backup via iTunes, then it may be easier for you to immediately make a reset through this program, and not the smartphone itself, for this - just click on the same "Overview" tab "Restore iPhone ...".

The reset through the "cloud" also in a certain situation will be convenient, because it allows you to erase the iPhone without using the device itself. Content and settings are erased in this case through the site:

Data recovery

Well, that's all - the matter is left for small - to restore the data, for this you need only when you want to specify where you want to "pull out" from. Smartphone will boot in mode initial setup Automatically after the smartphone itself, iTunes or ICloud will complete the data reset process.

Hardware failure

In case if restore iPhone. It was not saved, and it is still disconnected at a high level of charge, the case is definitely in the problem of hardware.

Battery

The first "suspect" is of course the battery. However, it is not a fact that the smartphone is turned off precisely because of the "dying" battery. What can be "evidence" here, besides outluts on a big charge? First, remember how old your battery, if you have an old i-smartphone model, for example, iPhone 4S, and you never changed the battery, most likely, the matter is in it. Also, pay attention to how quickly the smartphone is discharged - can the day or even have a moderate use of 3-4 hours? Another important moment - Losing a few percent of the charge is simultaneously - it is only permissible on "heavy" tasks - games, video viewing, etc.

Power controller

You new battery, the smartphone holds without recharging the day or more, the problem of simultaneous "reset" of a few percent for it is not typical, but it can turn off 20 or more percent? Then, most likely, the problem is already more serious - "covered" is not an acb, but the power controller. Its repair or replacement will cost more than replacing the battery.

Other elements

However, sometimes the case can be neither in the battery, and in no power controller, but in some other element of the iPhone, which could fail for one or another reasons - for example, water got into the body or you have a lot dropped to the device. However, we do not advise guess the best decision In this case, contact the pro.

Suitable

So, if software Methods Corrections of the problem did not help, we recommend sending an iPhone to diagnostics, especially since in most services today is a free service, and you can hardly figure out who "died" - battery, controller, or other element. Well, already on the results of the diagnosis you can decide what to do. If the problem is in the battery, you can buy a new one and install it yourself - it is not difficult, but the repair of other elements is likely to be much more difficult, so in this case, it is better to entrust the repair service.

Greetings! iPhone, like any other technically complex device, is subject to breakdowns. Yes, yes, there are no ideal gadgets (because of the news!) And Apple's smartphone is no exception to this rule. One of the most common ailments is independent turning off iPhone Without any reason.

Problems with iron. In 95% percent cases, this or battery, or the power controller. To start, it would be nice to figure out more information About the battery - to find out how many recharging cycles have already been, actual capacity, etc. Your iPhone and if it is very bad, then the replacement is inevitable.

In fact, it's all, because of what an iPhone can updo you with a periodic cessation of work. And now we will analyze the actions that need to be performed in order to fix this ailment and the iPhone stopped, without any reason, turn off itself:

As I said, if the problem is "iron", then in most cases either a battery or a loop and need to be changed. If there are no sufficient skills and repair experience - we appeal.
By the way, if a few more problems are added to the shutdown - blue screen, Different bands on the display, then the problem may be somewhat harder than the simple battery replacement. Microcracks are possible on the board and other terrible pieces. Here it is already necessary to diagnose. Although ... Read-Cause, there are some sensible ideas to combat this and other ailments.

Summing up or instead of afterword ...

As we found out, the reasons why the iPhone itself is turned off only two (we will not consider a special case using in the cold season) - it is either failures in softwareor problems inside the gadget.
