Why does the apple 6 mobile phone keep restarting when the battery has just been replaced

In the event of an automatic restart of Apple, it is recommended to deal with it in the following ways:

1. In this case, most of the time there is a problem with the system of the mobile phone, and it is impossible to boot it, so the only way is to enter DFU mode to flash the machine, first of all, install an iTunes on the computer;

2. After installing iTunes on the computer, then you have to re** an Apple system, that is, iOS firmware, this firmware version is as much different as possible from the current mobile phone version, and the firmware can be found as long as it is a glance;

3. After preparing the iTunes and flashing firmware, you can start to officially flash the computer, first open the iTunes installed on the computer, and then connect the iPhone with the computer with a data cable;

4. After connecting the mobile phone with the computer, and then press the power button and the volume reduction button at the same time, at this time Apple's logo will appear, don't care, continue to press the double button and don't let go, the Apple logo will disappear again, at this time, release the power button, continue to keep the volume reduction key and don't let go, and keep pressing until the computer sends out the prompt sound "Ding Dong" connected to the mobile phone, which means that it has entered the DFU;

5. When the mobile phone enters the DFU, iTunes on the computer will pop up a prompt to connect to an iPhone, click "Confirm";

6. When you click "OK", iTunes will appear as shown in the following figure, this time the more critical step is coming, the shift key on the keyboard, and then click the "Restore iPhone" button;

7. After clicking the "Restore iPhone" button, the system will open the folder, and then select the firmware that has been done before, at this time, the system will remind you, click "OK";

8. After completing the above steps, start to reinstall the system, and then on the way to restore the iPhone, do not turn off the computer or unplug the data cable, let alone turn off iTunes;

9. When the mobile phone system is installed, and the screen of the mobile phone appears in the following situation, it means that the mobile phone system has been reinstalled successfully, and then open it for use.

In such a situation, we actually only need to operate in one step, that is, to extend the charging time, wait for it for more than 10 minutes, because the power of the Apple mobile phone is less than 5% and it cannot be turned on.

Please wait patiently for 10 minutes, and your iPhone should be ready to turn on, if not, wait a few more minutes and tap the power button.

If the above operations are not working, it may be that there is a problem with the original charger and data cable, check whether the data cable is normal, check whether the original charger can work normally, you can try to change a data cable and charger.

Or it may be that the phone battery is broken, so you have to contact Apple after-sales for repair or replacement.

There are roughly four reasons why the battery of an Apple phone automatically restarts after changing the battery:

1. System firmware compatibility problem due to the rewriting of some functions of the iOS system firmware, which affects the compatibility between the original system firmware and the mobile phone hardware.

2. Application software plug-in compatibility problemsBecause these plug-ins have not been strictly tested by a third party after jailbreaking, it may lead to compatibility problems in the system, which will cause the Apple mobile phone to automatically shut down and restart.

3. Hardware problems: If you use a non-original charger, the charging voltage and charging current are not strictly controlled, it will also damage the battery of the iPhone, resulting in shutdown and restart.

4. Hardware problems: If there is a calculation error in the logic control unit, it is clear that the mobile phone battery is charged, and the motherboard power supply IC is missing at this level, and the mobile phone is automatically turned off and constantly restarted.

Finally, it is recommended to bring the device to the regular after-sales center for repair and treatment as soon as possible, so as to avoid problems such as aging battery, damaged motherboard, and system crash.

This phenomenon of Apple mobile phones is caused by poor interface contact after battery replacement. Insufficient battery power can also cause the phone to restart. Check whether the battery is in good contact with the phone, and clean the contact area with a small amount of alcohol or other solvents that are easy to detect.

The location in the picture above is at the power strip.

Ask if there is a problem with the system.

Is this happening before replacing the battery?

If you just replace the battery, you can rule out the system problem, the battery is hardware, and the replacement will not affect the system.

Summary. Hello, the sudden shutdown of the Apple mobile phone after changing the battery is because the battery replacement caused a problem with Apple's verification. The solutions are as follows.

1.System firmware compatibility problem due to the rewriting of some functions of the iOS system firmware, which affects the compatibility between the original system firmware and the mobile phone hardware, and the system firmware after jailbreaking may cause the Apple phone to automatically shut down. 2. Application software plug-in compatibility problemsBecause these plug-ins have not been strictly tested by a third party after jailbreaking, it may lead to compatibility problems in the system, resulting in automatic shutdown of the iPhone.

3. Hardware problems, battery leakage, if you use a non-original charger, the charging voltage and charging current are not strictly controlled, and it will also damage the iPhone's battery and cause shutdown. 4. Hardware problems If there is a calculation error in the power supply IC logic control unit of the motherboard, it means that the mobile phone battery is charged. In the case that the motherboard lacks a power supply IC layer, the phone battery is considered dead, and the phone automatically shuts down.

5. It is recommended to take the device to a regular after-sales center for maintenance as soon as possible to avoid mobile phone battery leakage.

Good. Hello, the sudden shutdown of the Apple mobile phone after changing the battery is because the battery replacement caused a problem with Apple's verification. The solutions are as follows.

1.System firmware compatibility problem due to the rewriting of some functions of the iOS system firmware, which affects the compatibility between the original system firmware and the mobile phone hardware, and the system firmware after jailbreaking may cause the Apple mobile phone to automatically shut down. 2. Application software plug-in compatibility problemsBecause these plug-ins have not been strictly tested by a third party after jailbreaking, it may lead to compatibility problems in the system, resulting in automatic shutdown of the iPhone.

3. Hardware problems, battery leakage, if you use a non-original charger, the charging voltage and charging current are not strictly controlled, and it will also damage the iPhone's battery and cause shutdown. 4. Hardware problems If there is a calculation error in the power supply IC logic control unit of the motherboard, it means that the mobile phone battery is charged. In the case that the motherboard lacks a power supply IC layer, the phone battery is considered dead, and the phone automatically shuts down.

5. It is recommended to take the equipment with the chain wild skin to the regular shed after-sales center for maintenance as soon as possible to avoid mobile phone battery leakage.

So what to do. It is recommended that you take it to the repair point where the battery was replaced, and re-test and test.

Because for battery replacement, if it is not the original battery, it will not pass the verification without careful light, including the difference between the voltage and the buried current, which may bring harm to other hardware of the mobile phone.

If your phone restarts repeatedly after replacing the battery, you can try the following methods.

1. The repeated restart of the mobile phone after replacing the battery may be due to the problem that the mobile phone has no power at all, because the power of the Apple mobile phone is less than 5% and cannot be turned on. At this time, you can extend the charging time and wait for more than ten minutes. If you still can't, wait a few more minutes and tap the on/off button.

2. If this method is not solved, you can try to force restart, some mobile phones have system problems, which will also cause the mobile phone to restart.

3. If it weren't for the above two methods that still haven't been solved, we would have to open the phone to check. If it is a small partner with a handicap, it is best to find a professional person to operate. After opening, we first have to look at the cable of the battery, it may be because the cable is loose, and poor contact will also cause the phone to restart.

At this time, you can press the cable tightly and try it.

4. If it is not a problem with the wiring, let's see if the screws are screwed by mistake and the top of the board is pierced. At this time, you need to see if there is a pimple behind the shell that you have pushed out, if there is a pimple, this is the problem. That's when it's time to repair it.

5. If you still don't find the key to the problem after all the above plans are done, it is likely to be a problem with the battery itself. At this time, it is necessary to replace it with a new battery or the original original battery to try it.
