Apple 4 connected to iTunes does not respond and can only charge 50

A little AISI Assistant can help you.

The possible reasons why the Apple 4 charging does not respond are:

1. The charger and plug-in cable are damaged or not plugged in properly.

Solution: Replug it in or find another charger to try it out. At this point, it depends on whether the charger indicator is loading.

2. The mobile phone battery is loose due to poor contact or damage.

Solution: Remove the battery board and use a needle to pull out the elastic strip to increase the elasticity, without replacing the battery, and observe whether the indicator is loading.

Cause:

1. It may be because of operational reasons, let the phone enter the recovery mode, press and hold the power button and home button of the mobile phone at the same time, and keep it for more than 5 seconds, so that the mobile phone can be forced to shut down, and the screen will be black.

2. If this is still displayed, it means that the system has been broken, and the system needs to be restored again, and the mobile phone and computer are connected.

4. When the phone is connected to the computer, open the iTunes software and prompt you to detect an iPhone device in recovery mode.

5. Then click on the Restore iPhone button in the iTunes window.

6. iTunes will connect to Apple's update server to detect the latest firmware system currently applicable to the phone, and after checking, click Restore to do so.

iTunes appears when the iPhone does not turn on and plugs in the charger: the system needs to be restored.

The operation is as follows: Step 2: Connect the iPhone with the computer with a data cable.

Step 3: In the summary interface, click "Restore iPhone" and follow the iTunes instructions to restore the system version.

How to deal with the iPhone not booting normally:

1. Check whether the iPhone has physical damage, such as: bending deformation or water ingress and other accidents;

2. Use the original data cable and charger to charge the iPhone, check whether the iPhone is responsive, and the battery may not turn on if the battery is insufficient;

3. Force restart your iPhone;

4. If there is still no response or cannot be turned on normally after the above operations, it is recommended to go to the local Apple official or authorized after-sales service.

It may be a bug with the system version.

It is recommended to restore the system to fix the bug issue by doing the following:

Step 2: Connect your iPad to your computer with a data cable.

Step 3: In the summary interface, click "Restore iPad" and follow the iTunes instructions to restore the system version.

It's time to enter recovery mode, plug in the computer, and then press and hold the home button + power button at the same time to restart.

How did you solve your problem? I've also encountered issues where it still won't turn on after restoring the system.
