Is It Possible to Damage Your Phone by Overcharging It With an External Power Source?
Phones and devices like tablets and laptops use lithium-ion batteries, which tend to increase capacity over time. This means you don’t need to charge them as often; however, it can also mean they run out of power more quickly when used excessively. How long a device will last on a single charge depends on screen brightness, volume levels, software running on the device, etc.
Charging your device from flat with an external charger may take longer than using the original one which came supplied with it or bought separately as an accessory. However, this won’t damage your phone (or another mobile device), but it is best not to keep your device charging overnight while you sleep; if it’s fully charged, remove the charger plug from the socket, but leave your device plugged in.
If your phone or other mobile device is not charging correctly, such as if the battery icon shows it has no charge even though you hooked up a charger, then there may be an issue with the battery itself rather than the phone.
A battery that isn’t working correctly should be replaced; if you buy another identical one and have the same problem, it is more likely that one of them was faulty when new.
On the other hand, if they both work fine when tested in another compatible phone, then there could be something wrong with your original device, which will need to be looked at by an expert or taken into a repair shop for further inspection.
