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.
What to do if the iPhone suddenly turned off as if the battery ran out, but in fact it is charged. If you have problems with an iPhone or iPad that turns off by itself when the battery is charged, use our instructions. See what to do if the iPhone starts turning off by itself.
As a rule, an iPhone, as well as any other mobile device, turns off when the battery level drops to a critical value. But sometimes there are failures in the operating system or with the battery, despite the fact that it is charged. Why does the iPhone turn off by itself?
Unfortunately, iPhone shutdown issues are not model-specific. Based on discussions on the forums, most often the problem occurs on new models 6, 6s and 7, but old devices are not immune from spontaneous shutdown - iPhone 4s and iPhone 5s.
But keep in mind that the iPhone can turn off, for example, in the cold or frost - this is a standard operation aimed at protecting the device from damage.
Let's move on to ways to eliminate the spontaneous shutdown of the iPhone.
The first way is to update the operating system
The first method from which to start searching for the cause and restoring the normal operation of the iPhone is to update the software version. Sometimes it will be enough to perform a normal update so that the phone stops turning off by itself. Especially updating the system is relevant in those cases, for example, if you previously used a test version of iOS on an iPhone or iPad.
To do this, go to the Settings app, then on the General tab - Update, check if there is a new version of iOS available for our smartphone. If yes, install it and wait for the iPhone to reboot.
The second way is to reset the settings
Restoring factory settings is also a very simple method, which can be extremely useful when errors occur in your smartphone. If the iPhone turned off by itself for the first time (before this, there were no such problems, except when it turns off in the cold) and you assume that the problem is not in the battery, turn it on again.
If the restart did not help and the iPhone still turns off by itself, proceed to restore the factory settings. To do this, open Settings, then go to the General tab and find Reset. With it, you can erase all data and return the iPhone to its original state. But before performing a reset, you should make sure that you:
- made a backup copy of all data;
- Disabled iCloud account in settings.
The first item is needed in order not to permanently lose all our files, especially contacts. The second will allow you to perform a full reset of the iPhone. Without turning off Find My iPhone in the iCloud tab, you won't be able to reset your phone to factory settings.
If the problem persists and the smartphone still turns off by itself, we will try to charge the battery. First you need to completely discharge the battery - to zero. But before that, be sure to make a backup copy of all data - as in the previous method.
When the battery is low, we connect the iPhone to the charger better through a proven cable.
If, for example, a problem with the phone arose due to a malfunction of the charger, then we simply won’t charge the iPhone. If you are not sure about your charger, you should test how the phone charges using a USB cable connected to a computer.
The fourth way is to update the firmware via DFU
If you are not afraid to damage your phone, you should try putting it into DFU mode. Then install the latest iOS operating system using a computer and iTunes.
The method will allow us to update our smartphone in a 100% safer way. If the iPhone turns off by itself through failures in the operating system, then DFU mode should solve them once and for all. In this case, you also need to back up your data and disable your iCloud account first. That is, just like in the second method.
If these methods did not bring the desired result and the iPhone still turns off by itself, you need to take it to a service center. Even if the smartphone is not under warranty, this should be done. Diagnostics to find out what is not working in our iPhone can be absolutely free, and thanks to it we will at least know whether it is worth investing in repairs or start saving for a new device.
The problem when the iPhone 4, iPhone 5, iPhone 5s, iPhone ce, like everyone else turns on and off is not very common, but the number of requests on Apple sites indicate that it exists mainly among iPhone 5 users.
Sometimes an apple burns and only after that everything goes out. There are many reasons, but they can be divided into two parts: opening and mechanical.
If you have the second option, then I can’t help, because for example it’s impossible to replace flash memory remotely.
As for the second point, the problem is solved independently. For this, there is even a program for eliminating system errors in iOS.
NOTE most often this is a problem in the firmware, which is solved independently. How to reflash.
iPhone after turning on goes out and turns on again - try the program
The program is called ReiBoot (maybe someone has already used it). Download
How to use it. The main thing is that at least a cable appears when you turn it on. After installation on the computer, connect the iPhone to it with a cable, and as soon as the program detects the phone, click restore.
In addition, you can also fix many errors in the operating system of your smartphone.
An apple appears in the iPhone and goes out - check the battery
If the iPhone lights up and goes out, then the battery may be damaged - the charge / discharge cycle has reached the limit.
In such cases, you need to contact one of the authorized Apple service centers to replace the battery.
An apple appears in the iPhone and goes out - try a hard reset
One of the first things you should do if you have an issue with your iPhone is to hard reset.
You can do this by pressing and holding the home button and sleep/wake button for at least 10 seconds. Do not release the buttons until the Apple logo appears.
If you have an iPhone 6, then an unexpected surprise may appear. Although the phone is fully charged, sometimes it can suddenly turn off.
This situation often occurs especially when the smartphone is kept at low temperatures. Apple responded to this problem and launched a program to replace defective batteries - everything will be free.
You should be especially interested if you own a phone that was manufactured between September and October 2015.
According to Apple, the defect relates precisely to these terms. You can have the battery replaced at one of Apple's services, and those who have already replaced it themselves may be eligible for a refund from Apple. Good luck.
For the owner of an "apple" device, the biggest nuisance is the ever-glowing "apple" on the display or even the "black screen". The device has entered an endless boot loop or does not turn on at all. Often this is a consequence of a malfunction of the gadget's motherboard and only a service center can help.
But at the same time, many of the errors can be corrected without leaving home, programmatically or with the help of simple tools at hand. You need inexpensive tools, a computer, free time and attentiveness. And you also need access to a parts store, where you may have to buy failed components. As they say in advertising slogans - "Why pay more?".
So, let's see what problems can happen when the iPhone or iPad turns off by itself, why the apple lights up and goes out on models 4, 4s, 5, 5s, 6, 6s, what to do in such cases.
Why the iPhone does not turn on: we make a diagnosis
Outwardly similar symptoms can be the result of completely different malfunctions. The correct diagnosis is 90% success, so below we will analyze in detail the possible options for breakdowns.
Doesn't turn on
The device cannot turn on, and there are several reasons for this:
iPhone won't turn on, apple light on and off
The white “apple” glows on the screen either continuously, until the battery is discharged, or the device is cyclically rebooted every few minutes. This may happen for the following reasons:
Troubleshooting
All malfunctions are traditionally divided into problems with hardware and software. To fix software errors, we need a USB cable and a computer.
For the treatment of iron, the list will be much wider:
- A suction cup with a diameter of 4-5 cm. You can buy an expensive one, in a radio store, or you can buy a cheap one, and those with which soap dishes are attached to the wall in the bathroom. They will work the same.
- Soldering iron, acid-free flux and thin solder.
- Combined instrument (tester), can be the most inexpensive.
- Watch screwdriver set.
- Universal charger "frog"
- Alcohol, preferably isopropyl.
- Brush with medium bristles. The edge must be trimmed so that it is even.
- If your eyesight is not very good, be sure to have a magnifying glass on a stand.
- A box for fasteners and small parts, an uncluttered table and a bright lamp.
Deep discharge battery
A battery controller blocked as a result of an extreme discharge will not allow it to be charged by standard methods.
Therefore, to fix the problem, you will need to open the device, dismantle the battery, and check it. If the battery is in good condition, charge using a universal charger. How to do this, let's try to figure it out using the example of the third generation iPhone, since it will be the most work with them.
- Removing the SIM card tray
- Using a screwdriver, unscrew the two screws, to the right and left of the cable connector.
- Place the suction cup on the centerline of the iPhone, as close as possible to the Home button. Slowly and carefully pull the suction cup up, disengaging the lower part of the screen module frame from the iPhone case.
- Raising the lower edge of the display module by one and a half to two centimeters from the case with a plastic spatula, we sequentially turn off three cables in the upper part of the case. We do this very carefully - the loops are easy to damage. After disconnecting the cables, the display module can be removed and set aside.
- On the main board, disconnect the button cables, headphone jacks, antennas and speakerphone.
- We unscrew all the screws around the perimeter of the device board.
- With a plastic spatula we hook and pull up the camera module.
- Move up and back to remove the board from the case.
- The battery is glued to the bottom of the case with double-sided tape. We warm up the case on the reverse side with a hairdryer (without fanaticism) and pry the battery with a plastic spatula, remove it from the case.
- Using a tester, we measure the voltage at the plus and minus contacts. If it is below 3.2V, we connect the battery to a universal charger, as shown in the figure.
- If the voltage is higher than 3.2V, we connect the universal charger to the contacts of the battery controller.
- We charge the battery for 1-2 hours, controlling the voltage with a tester. When it reaches 3.7–4.2V, we stop the charge.
- We install the battery in the iPhone and assemble it in the reverse order.
- We are trying to turn on the "apple".
Power button not working
The power button consists of two elements: a film switch and a plastic pusher, it is he who sticks out of the case and you press it with your finger. When enough dirt accumulates between the pusher and the button, the pusher cannot reach the button and the iPhone does not turn on. First, let's try to blur the accumulation of dirt with alcohol, medical or isopropyl. In no case do not take vodka, toilet water, glass cleaner for this operation. In addition to alcohol, these liquids contain a fair amount of water, which will remain inside the device and cause corrosion.
Cable connector does not work
The cause of this malfunction may be either contamination of the connector or damage to the contacts in it. To fix the problem, you need to do the following:
The battery is dead and needs to be replaced
The simplest breakdown is to disassemble the iPhone and replace the battery with a new one. You can buy a battery in one of the many online stores selling spare parts for mobile phones.
If you do not contact the service center, the chances of purchasing an original battery for replacement are zero. When buying a battery, be sure to check it for leaks, swelling and corrosion. If possible, check the voltage with a tester.
The device hangs on the "apple" after resetting to factory settings
This problem is most often found in devices bought from hand or in online stores that sell used equipment. Most of the iPhones brought from abroad for resale are contract devices of mobile operators. In order for such an iPhone to work with any operator, it needs to unlock the radio module. Sellers do this procedure themselves, because they position the device as Neverlock, that is, it works with any SIM-cards. But not everyone informs the buyer that such a device cannot be updated via iTunes or reset to factory settings - the result will be a “brick” with a white apple on the screen.
To return the iPhone to normal working condition, you need to do the following:
iPhone is in DFU mode
The device will be able to exit DFU mode on its own only after discharging the battery to zero. If you do not want to wait such a long time, you can solve this problem programmatically:
With iTunes
- Connect your device to your computer and launch iTunes.
- Wait for iTunes to recognize iPhone in recovery mode.
- Simultaneously press the "Home" and "Power" buttons on the device and wait for the iPhone to restart.
Using the TinyUmbrella program
Amat victoria curam - victory loves preparation. This catchphrase is equally suitable for troubleshooting "apple" devices. Visit thematic resources on the network. Study the theoretical part, prepare your workplace, stock up on the necessary consumables and your iPhone will definitely come to life!
If luck didn’t smile at you or the breakdown turned out to be too serious, you can always contact the wizards of the service center.
Hey! To begin with, it is worth describing the situation in more detail, otherwise it may not be clear from the title what the author means. Moreover, I recently encountered this problem personally, so the picture is right before my eyes and it will not be difficult to describe the situation :) And the following happened - my rather old iPhone 5s was completely discharged, as they say "to zero", and it would seem that there is nothing criminal, plugged it in and went about my business...
I return after a while, and I see a very strange and inadequate behavior of the device - the iPhone turns on, the screen lights up for a while (an apple appears and even a glimpse of the password entry) and immediately the display goes blank and the phone turns off safely. And that's what happens all the time. For the sake of the experiment, I waited another 20 minutes - nothing has changed (only), but continued to turn on and off with enviable constancy.
I’ll run ahead and say that I managed to solve the problem on my own and without visiting a service center, and in a fairly easy way. But first, about how to prevent such a situation and what you should pay attention to:
- Do not discharge the device until it is completely discharged, especially if the battery is no longer new.
- Do not try to force it, in cold weather you need a lot more energy to start.
- Use original accessories - the battery will only thank you.
Actually, almost all these reasons coincided with me - it was relatively cool in the room, the battery has definitely been there for a couple of years (although it holds), only the wire and charging are original.
What happens in the end? When connected to a charger, it turns out that all incoming energy is spent solely on loading the system and backlighting the display. This energy is not enough, it cannot accumulate, the iPhone seems to turn on, but immediately discharges and turns off. And then everything will repeat again. Here is such a vicious circle.
How to get out of it?
- Use a more powerful power adapter. The one that comes with the iPhone gives out 1 ampere and it is clearly not enough in such a situation. So you need something stronger, for example, from the iPad. It has 2.1 amps at the output and is able to provide more energy, which is enough to turn on. Is it safe? Apple says that, and it makes no sense not to believe it.
- In the case when there is no other adapter at hand, you need to do the following operation - and leave it on charge for a while in this state. In this mode, the screen does not light up and the system does not boot, which means that there will be no energy consumption and all of it will go to charge the battery. After 20-30 minutes, we turn on the iPhone and are glad that the shutdowns have stopped.
- This option is clearly "an amateur" and will require some skill from you. It consists in connecting the wire to the device for 2-3 seconds and without waiting for it to turn on, immediately pull it out. And in such small portions, recharge the battery to the state that is enough to fully launch the iPhone.
Finally, I would like to note that the situation discussed in this article is, of course, not normal and in a good way, the battery must be changed so that there are no other surprises in the future. But here everyone decides for himself.
