Phone hardware reasons. For example, water ingress, dampness, falling, etc. Send it for repair

All-in-one machine, press and hold the power button for 15 seconds, if it can't be turned on, try again after charging for half an hour.

Let's start by determining whether it's a hardware or software issue.

There are the following reasons why your phone won't turn on:

1 If the phone is not an all-in-one phone, take out the phone battery, and then try it back on.

2 If there is an SD card on the phone, take out the SD card and then press and hold the power button to turn off and restart it.

3 Save the important data on your phone and restore it to factory settings (in the shutdown state, press and hold the volume plus key and the shutdown button, and let go when the boot screen appears, then you can enter recovery.) Go to Recovery >Chinese >> Clear Data >> Empty all data).

If you still can't, it is recommended to bring the relevant documents and invoices to the network engineer for inspection and maintenance.

1. Check whether there is a problem with the charging cable. Charging requires the use of the original charger and data cable, the use of non-original chargers may lead to slow charging, non-charging, touch screen failure and other abnormal phenomena during charging.

7.System ROM problems: For system ROM problems, please make sure that you have some flashing experience or mobile phone system knowledge. You can choose to re-flash the device to try it or use the following method to clear the system's battery information.

Make sure your phone is rooted, I won't go into detail here due to space issues, please see my other article on root. Enter the recovery mode, select Wipe, then WipeBatteryStatus, and then Reboot.

If your recovery only has WIPEdata or FACTORYRESET, please back up all the data after WIPE!

In general, it is still very easy to solve the problem if the phone does not charge, as long as you check it carefully and find the right medicine for the problem.

None of the above situations can be checked by a professional mobile phone repair place.

1.The electrode contacts of the battery are dirty, the contact resistance is too large, and the voltage drop is too large, and the host thinks it is full and stops charging when charging;

2.The internal charging circuit of the mobile phone is faulty and cannot be charged normally.

3.If there is a fault inside the battery, the judgment method: Problem 1 can be wiped clean with a clean eraser, which can generally solve 80% of the problem.

Question 2: You can find a universal charger to try charging, if it can be used normally, it is a mobile phone problem, and you will use a universal charger in the future.
