Battery bulge problem, please do not continue to use the bulge battery. If there is a bulge, try to replace the new battery in time or take it to after-sales repair.
The cell phone battery will appear bulging, generally caused by the following reasons:
1. Serious overcharge
That is, for a long time, the phone continues to charge the phone after the battery is shown to be full, causing greater loss to the battery.
Second, the current is too large when charging
Since the mobile phone only protects the power short circuit, the use of non-original chargers makes the current too large to affect the battery itself, so the original charger should be used.
Third, the battery itself
Because the battery itself is a consumable, after the mobile phone is used for a certain time, the battery itself can withstand the peak, and the normal charging operation will cause the battery to be damaged.
