Don’t we all wish our mobile phone battery life could last forever, so we won’t have to worry about charging? well, its such a bummer that’s not possible with today’s technology but close enough we could optimize our battery life to make it last the day or days depending on how we use them.
The ability of mobile phone batteries to store energy reduces as the number of the charge and discharge cycle increases. This is the demerit of lithium-ion batteries mobile phones use.

The way we handle our devices today affects the charge capacity in the future because the ability of lithium-ion batteries degrades.
The degradation can be minimized by following some simple steps below!
