The battery is broken. There is no choice but to buy new ones. The originals usually cost over $1,000, and the others are much cheaper. But the quality is difficult to say. There are too many fake batteries. Find a reliable place and it is safer to choose a third-party brand battery.
Damage to the battery is very easy if it is not properly maintained, such as leaving it plugged in or exposing it to heat. Typically charge and discharge every few days. If power is still available, you may want to remove the battery. Some repair shops claim to be able to repair batteries, but most of these are practices that reduce safety.
Will the battery of a cell phone that has been on the market for a year still look new?
Hello, currently the batteries of cell phones uuse lithium batteries, which have no memory effect, so users can charge them as they go and stop charging when they are full
1 New The first time. the phone is charged, it is fully charged.
2. Do not wait until the battery is in a low-power state before charging the battery. Try charging it while you use it to extend battery life.
3. Please remove the charger in time after the battery is fully charged to avoid charging for a long time, otherwise it may damage the battery or shorten the life of the charger.
4. Please try to use the standard charger. It is recommended not to replace unofficial batteries.
Buying a cell phone battery that has been on the market for a year will not be as good as new: the reason is that the storage function of batteries at thecell phone ithium will be reduced after leaving the factory.
The following table illustrates the reduction in battery capacity according to two parameters
Charging temperature 40% charge 100%
0°C capacity 98% after one year - 94% capacity after one year
25°C 96% capacity after one year 80% capacity after one year
40°C 85% capacity after one year 65% capacity after one year
Capacity at 60°C is 75% after one year and 60% after three months
Storage temperature accelerates decline of the battery capacity.
