Phone overheating
It's normal for your phone to get a little warm while you're using it. This problem is more common in the summer, but there's a limit. If you notice your phone overheating or burning your hands while using or charging, there 's a problem with the battery. Therefore, remove the phone from charging or stop using it.
swelling of the battery
If a battery is overcharged, it produces a small amount of gas. Once the battery has generated gas, it will increase with use. This causes the battery to swell.

strange smell
Sometimes you won't even need to touch the battery to diagnose a problem. If your phone is emitting a strange odor, it could be due to battery leakage.
