Can't charge the battery?

First of all, the mobile phone problem.

There is a charging problem inside the mobile phone itself. This requires taking the mobile phone to the designated national warranty point for inspection and maintenance.

Before sending, you must first make sure that it is really a mobile phone problem. Please try to replace it with the same model of high-quality mobile phone battery and charger. If you put someone else's battery into your mobile phone with your own charger, and it still doesn't work, try using someone else's charger. If it still doesn't work, it means that there is something wrong with your own mobile phone, and you have to send it to repair it yourself!

Second, the charger problem.

If you use the replacement method mentioned above, you can use someone else's charger to charge, that is, your charger is broken. If there is a warranty, please repair it quickly. If not, please send it to the after-sales service point of your brand mobile phone and ask the manufacturer to help you repair it. Because manufacturers are more aware of their products, maintenance will be guaranteed. Don't send them to street stalls for repair.

Third, the battery problem.

If you can still charge normally after replacing another good battery, it is your battery problem. In the case of determining that there is something wrong with the mobile phone battery, first take out the mobile phone battery to see if it is swollen. Is the metal contact position rusted? If it bulges, it means that there is something wrong with the battery cell and it has been damaged; Or the cycle life of the mobile phone battery has been reached; Or there is something wrong with the battery protection circuit board.
