If you use smartphones a lot the battery can go within a day which isn't much

I charge mine every night, but it rarely if ever needs more.

I need about two and half charges a day on my Samsung Galaxy S II, so I
carry extra batteries and have a separate battery charger. Problem solved.


I found my HTC smartphone needed more than one charge a day so I
bought an aftermarket battery with 50% more capacity which, although
slightly bigger, still just fits in the battery compartment. It gave
the phone the extra time needed so I only charged it once a day.

But what made the biggest difference was upgrading the Google OS to
4.0 Ice Cream Sandwich. Power management is much better and I can get
two days out of one charge as long as I avoid a couple of apps that
are particularly power hungry.
