since im using my own custom battery i charge every other day, but i am using my phone very heavily, i really have to use it non stop if i want to use the battery in one day.
Any my new 2763mAh battery really gives me peace of mind that i don't have to limit myself from using my phone when i know i will not be near a charger for some time.
I can remember when i got it i really hated the fact that i could use up the battery pretty "quick", and that's why i got on getting battery's and start making my own battery since i don't want to pay 95$+ for the mugen battery.

My high usage includes always having my custom brightness at level 3 (= between 4 & 5 without custom brightness)
