1 Power supply is not enough
With unstable power sources or too weak supply, users can completely encounter a situation where the phone is charging but the battery does not enter. It is also possible that the electrical outlet has been damaged but we do not pay attention to it. Try charging with another outlet to resolve this battery failure.

Therefore, to ensure effective and safe battery charging, you should equip your phone with quality, original phone.

A faulty operating system is one of the reasons why the phone does not charge the battery. Error operating system is a very normal thing on phones because no system is perfect, this depends on how we use it.
In some cases, when you update the application or the operating system, it may lead to some errors for the device due to conflicting application data or the update has an error during the download and installation process.
To fix this error, do a factory reset on the phone. Before doing this, users should back up all important information in the machine because the factory reset process will erase all data.

Applications that generate errors on the device besides causing the phone to drain the battery quickly are also a reason why the phone does not charge into the battery.
Please try to close the applications running in the background, restart the device and continue charging.

If your device has been dropped, bumped, or in the water recently, this is more likely to happen. At these times, do not try to open the machine to check, but go to the nearest service center for the best inspection and support.
