Why iPhone turns off at 70 percent charge. How to solve iPhone random shutdown issue. Contacting a service center

Apple products are famous high quality and operational reliability. However, there are also problems with them. Often, iPhone owners turn to service centers for their smartphones to turn off spontaneously.

Phones can turn off randomly - without obvious signs of low battery, while using applications, and even during a call. There are several reasons for this: we can talk about both software and hardware defects. mobile device. How to solve the problem of spontaneous shutdown of the iPhone?

1. Hard reset your iPhone

To solve the problem with the spontaneous shutdown of the iPhone, a hard reset of the device will help, as a result of which the temporary data is reset. To do a hard reset, press and hold the top power button and the home button at the same time. You need to hold them together until the Apple logo or a graphic message about the battery charge appears on the display.

2. Connect your iPhone to the adapter

Connecting the phone to the power adapter helps some users. The smartphone turns on, fully charges and continues to work as before. If after a while the failure repeats, it is likely that the battery is failing.

In a situation with a spontaneous shutdown of the iPhone, returning the gadget to its original state will help - reset operating system. The operation is quite simple and can be done on the gadget itself. You can clean up your iPhone and iPad using the phone itself, namely, from the Reset section in the main iOS menu. Various reset options are available here. MacDigger talked about this in more detail.

If none of the above methods helped you, most likely we are talking about a serious hardware defect. To determine the problem, please contact service center where experienced craftsmen can carry out repairs.

Often, owners of expensive Apple equipment are faced with the fact that the iPhone turns off at 20 percent. If you are familiar with such an unpleasant problem firsthand, this article will help you deal with it. In a number of cases, you do not have to resort to the help of specialists and spend your money on repairs. Many problems can be fixed on your own and quickly enough.


Why iPhone turns off and what to do about it

If the indicator of your smartphone shows a sufficient charge level (for example, it is in the middle), but then the device suddenly turns off because it is discharged, this brings great inconvenience. In some cases, you can deal with this problem on your own. Listed below are a few common problems with Apple smartphones and easy ways to fix them:

  • indicator problem– the device shows incorrect information about the degree of battery charge and, for example, at 50 battery charge, in fact, the device is already completely discharged; to deal with the malfunction of the indicator, you must first fully discharge the battery of the phone, and then fully charge it
  • device software problem- in order to fix this problem, you should return to the factory settings - backup and restore, but do not forget to backup all data, as they may be lost
  • charge controller malfunction- if the problem lies in the power controller, it can be dealt with with a simple hard reset; in order to perform a hard reset, you need to hold down the "Home" button and the "Power" button at the same time until the Apple equipment is turned off

To troubleshoot the software, launch iTunes and connect your smartphone to your computer, back up your data, and then click the Restore iPhone button. All you have to do is restore the data from the backup, and your device will work correctly again.

Do not forget that at low temperatures, a charged battery of any iPhone model sits down faster than in warm weather. Low temperatures do not affect the battery capacity in any way, but so that it is not discharged at the wrong time and does not sit down too quickly, you can put on a special case and carry the phone in the inside pocket of the jacket. In the cold, it is recommended to avoid photography and other heavy loads. In such a situation, the phone can suddenly sit down at 80 percent, half and 30 percent of the charge.

If your device may suddenly turn off at almost full or half charge, charges too slowly and not fully, the problem may be that you are not using the original charger, but a poor-quality analogue. In this case, all you need is to replace the charger with a suitable one.

Other signs of breakdowns

The fact that your iPhone turns off at 20 percent may not be the only “symptom” of a breakdown. Other common faults are listed below:

  • iPhone turns off when taking a photo even though it's more than half charged
  • phone charges to 3 percent or 1 percent and turns off
  • smartphone turns itself off when fully charged
  • iPhone turns off and shows blue screen
  • phone dies too fast (may turn off at 70 percent, 60 percent, or 35 percent)
  • when the charger is connected, the battery does not charge or charges only halfway
  • the phone spontaneously goes into standby mode at high loads or even in their absence

Most likely, when such signs appear, it will not be possible to fix the breakdown on your own, and you still have to turn to the help of qualified specialists.


When to Call a Specialist

If you've tried all of the above methods, but your iPhone still turns off at 40 percent, 15 percent, or 10 percent, you should contact a professional like Yudu. Perhaps the reasons why iPhones turn off are much more serious, and they are not related to software, but are related to the “stuffing” of the iPhone. It could be:

  • battery failure
  • loop breakage
  • microcracks on the board
  • connector failure
  • other hardware problems

Experienced craftsmen registered in Yuda will diagnose and accurately identify the cause of the breakdown. Using special tools and original spare parts, they will perform all the necessary work - they will install a new battery, repair the connector, replace the cable, etc. Upon completion of the work, you will receive a serviceable device that will serve you for a long time. The master will provide you with a guarantee for all work performed and give advice on handling the phone.

Greetings! iPhone, like any other technically complex device, is prone to breakage. Yes, yes, yes, there are no ideal gadgets (that's news!) And the Apple smartphone is no exception to this rule. One of the most common ailments is turn off iPhone without any reason. That is, there seems to be charging, in general, everything works fine, and sometimes it will take it and turn off. Moreover, these "tricks" occur periodically and quite often!

We will now find out about the reasons for such a breakdown, as well as whether this is inherently a defect at all (and in some cases everything is logical and more or less normal). And of course, we will find out what can be done with a constantly turning off iPhone at home, without visiting a service center (we will always have time there!). Let's start!

Why does the situation arise when the iPhone turns off by itself:

  • Spontaneous reboots may be due to software issues. For example, if you have an operating iOS systems or its jailbreak, then the periodic shutdown should not be surprised. Although such options do not only occur in these cases.
  • If this happens on the street during the cold season, then this is just the case when turning off the iPhone (even if there is still charging) is a completely logical phenomenon. Read more about.
  • Iron problems. In 95% of cases, this is either a battery or a power controller. To begin with, it would be nice to find out more information about the battery - to find out how many recharge cycles have already been, the actual capacity, etc. your iPhone and if it is really bad, then replacement is inevitable.

In fact, this is all because of which the iPhone can upset you with a periodic cessation of work. And now let's analyze the actions that need to be performed in order to fix this ailment and the iPhone stopped, for no reason, turning off itself:

  1. Fight different software bugs leading to reboots is best with . As a result, we get a “clean” device with the latest current firmware at the moment. If your smartphone has important data, be sure to create it or .
  2. It is possible that the iPhone simply cannot turn on, the screen lights up and the device itself immediately turns off. Know that simply plugging into a power outlet will not save him. about what to do in such cases.
  3. A hard reset might help! At the same time, we hold down two buttons - Home (round under the screen) and Power (turn on) and hold them for 10-15 seconds before the screen lights up. Updated! This combination does not work for all models - here. There is no need to worry about your data, with this manipulation they will not be lost.
  4. As I said, if the problem is “iron”, then in most cases either the battery or the cable is to blame and they need to be changed. If there are no sufficient skills and experience in repair, we turn to the service.
  5. By the way, if a few more problems are added to the shutdown - a blue screen, various stripes on the display, then the problem can be somewhat more difficult than a simple battery replacement. Microcracks on the board and other terrible things are possible. This is exactly what needs to be diagnosed. Although ... read about, there are several sensible ideas for dealing with this and other ailments.

Summing up or instead of an afterword ...

As we found out, there are only two reasons why the iPhone turns off by itself (we will not consider a special case with use in the cold season) - these are either failures in software, or problems inside the gadget.

And if you can and should fight the first ones on your own, then in case of any breakdowns, it is better to turn to professionals. Especially if you know exactly what is available for your device has not expired.

P.S. If you have any questions or questions, then write in the comments (if possible by putting a "like"!) - I will help you as much as I can, as they say.

Sometimes even an iPhone with good batteries starts to fail. In some cases, there may be battery chemistry problems. It happens that the owners of phones leave them on heating devices (on a dashboard under the sun) or the like, thus "burning" them. Often a buggy battery can be fixed using the tips below. So, if your iPhone suddenly turned off and the battery was showing 20%, 30%, or even 50%, here's what to try!

Note. Apple has a program for iPhone 6s owners who are experiencing an "unforeseen shutdown problem." This applies to the iPhone 6s, which was released between September and October 2015. If you think this applies to you, check serial number on apple.com to see if you can replace the battery for free.

1. Update to iOS 10.2.1 or later

In earlier iOS versions If a power-hungry app such as suddenly increased demand for power and your battery was already weak due to excessive charge cycles or exposure to heat, your iPhone may have mistakenly shut down before the battery dropped to zero to protect itself. Apple updated battery management in iOS 10.2.1, fixing the issue 80% of the time.

So, if you are still on the old firmware, update your device to iOS 10.2.1 or later. The latest version is always better as it fixes bugs and security vulnerabilities.

2. Hard reboot

Whether the iPhone really started shutting down earlier or if one of the processes is draining the battery quickly, a forced restart can help. Remember when a computer is glitching you do a "windows reset", it's not a joke, sometimes bad bits get stuck and need to be "flushed".

  1. On iPhone 6s and older phones, simultaneously press and hold the " nutrition" and " Home».
    • On an iPhone 7 or later, press and hold the " nutrition" and " Volume down».
  2. Hold them in this position until you see the Apple logo.
  3. Let go.

After restarting your iPhone or iPad, wait and see. If it stays on and functional, you're good to go. If not, or if it won't reboot, go to the next step.

3. Connect

If your iPhone or iPad runs out of power quickly, after connecting it to the charger, make sure it starts charging and can read the battery level. The absence of a charge indicator means that the battery is not charging. Partial or full charge - 20%, 30%, 50% or more - means that you may have another problem.

Thus, plug your iPhone into the charging cable, plug it into a power outlet or USB port, and start charging. Let it charge for an hour. If it doesn't seem to be charging, try using a different charging cable, a different USB outlet plug, or a different USB port on your computer. After that, keep an eye on your iPhone or iPad and see if it turns off again. If not, great. If yes, keep reading.

4. Recovery

Having tried simple tips, it's time to try more complex ones. In this case, restoring your iPhone. iTunes is a safer option than iCloud because it actually downloads, reinstalls, and reloads your data instead of doing everything locally and on your device. This can sometimes loosen up bad bits that even a hard reset or restore from iCloud won't fix.

  1. Connect your iPhone iPod touch or iPad to iTunes on a Mac or Windows computer using a cable.
  2. Go to the " Device" in the upper left corner.
  3. Click " Backup».
  4. Wait for the backup to complete.
  5. Click " Restore».
  6. Wait for the recovery to complete

When you're done, check to see if your iPhone or iPad is turning off. If so, cheers! If not, there is more to try.

5. Contact Apple

Sometimes a problem really is a problem. Like any electronic device, batteries can fail and cycles can be short. If you've tried everything and your iPhone continues to turn off unexpectedly before the indicator reaches zero, go to a service center and change the battery.

You also have a chance that Apple's diagnostics may be that the battery failed prematurely due to their fault, in which case, you can get a free replacement.

If you don't live near an Apple Store, you can call 1-800-MY-APPLE to set up mail repair. If you don't have AppleCare, you may have to pay for the call, but it's less of a waste than a dead iPhone or iPad.

Have you solved the problem?

If you have an iPhone that shuts down before the battery is really dead and one of the above fixes worked for you, let me know! If the unwritten method above helped you, let me know, thanks!

If your iPhone is behaving strangely turning off on its own, even with 15% or 30% remaining charge, then you should know that this is not news and you are not the only one experiencing this problem. Users have been reporting this issue all over the place since the release of iOS 9. And even now in 2016, many of us are still facing this issue.
If your iPhone suddenly turns off even though there is sufficient battery power, try the following troubleshooting tips:

1. Perform a hard hard reset

Usually a hard reset solves this problem. A hard reset is similar to the procedure: “did you try turning the device off and on again”, but at a deeper level of the operating system. Usually reset occurs to factory values.

To hard reset your iPhone with a physical home button (any iPhone model prior to iPhone 7), press and hold both " Sleep/Wake" and " Home” within 5 seconds. The iPhone will restart, you will see the Apple logo flashing and the iPhone will come to life.

On models, press and hold the “ Sleep/Wake" and " volume down” to perform the hard reset procedure.

2. Check if you have the latest versionOS?

Users first reported this problem when iOS 9 was released. The problem was random and the pattern of its occurrence has not been clarified.

But users reported that updating to the latest version usually fixed this issue for them. At the time it was iOS 9. At the time of this writing, it is iOS 10.1.

Therefore, after starting up and with the iPhone running (preferably after performing the hard reset procedure), go to " Settings" -> « Main» -> « Software Update" and update to the latest OS version.

3. Charge your device

If your device is unresponsive and nothing works (not even a hard reset), just put your phone in the charger and leave it there for an hour or so.

If that doesn't work, try a different cable or charger, or try charging your device with your Mac.

4. Discharge the battery to zero and then fully charge

If the problem is related to the battery level indication (say, the battery statistics are not correctly registered in the system), then the solution may be to discharge the battery to 0% (until the device itself turns off due to lack of power) and then charge it to 100 %.

5. Recovery viaiTunes

One last resort might be to restore your device to factory new condition through the iTunes app.

Step 1 : Connect your iPhone to your Mac/PC and launch iTunes.

Step 2 : After recognizing your iPhone in the app, select the device tab and select " back up now» to create a local backup your device.

Step 3 : After completing the backup, click on " Restore iPhone". After that, the process of downloading the latest version of iOS software, completely deleting data and installing a new operating system on your device will begin.

At the end of this procedure, your phone will be restored to the state when it first fell into your hands. After that, you will be prompted to restore your phone data from the backup you saved before. After the data recovery process, all your apps and their data will be back on your iPhone.

6. ContactApple

If you have done all the above procedures, then we have eliminated all possible causes of your iPhone suddenly turning off even with a sufficient level of charge at the software level.

This is all we can do ourselves. Your device may have a damaged battery or other internal electronic component. If your iPhone is about 3 or more than 4 years old, then it probably is (I have even seen iPhone 6s with similar defects).

In this case, the best thing to do is call support or visit your nearest Apple support or Apple store. If your device is still under warranty or has an extended warranty from Apple Care+ (always a good idea), then Apple can exchange your device for a new one, or you'll pay for your device to be repaired.
