But Apple's battery is not the same as ordinary cell phone batteries
Lithium battery is that you do not need to rush 8-12 hours to activate because the factory has been activated for you when the factory
That is, if the battery power above 20% you can also charge no harm
However, it is recommended that you use half a cycle charge
That is less than 20% of the charge when the middle of the battery is not broken until only to 100%
And do not need to boot things turn off can be like 3G positioning brightness roaming notifications and so on
Normally the new battery is the same in 400 cycles
Is 400 times the battery capacity will not change after 400 cycles capacity may only be less than the original 85
Depends on how you keep it.
