Batteries are just too essential... Here in Nigeria we need batteries that can stay for up to 4days, I mean improvement is welcome but the risk that might be attached to it is my fear
All this 6000mah batteries are made for Nigerians I guess... Just saying
The capacity or size of a battery does not directly show the performance of such battery. I've seen the 2000mAh out perform a 4000mah battery. It all comes to efficiency of the processor and software. Some phones are just energy guzzlers, a 10,000mAh battery cannot even last for a full day of high usage.
