my personal experience using iphone 3g, i charge it using charger when it shows 20% and it will take about 1 and half hour to 100%. But,i will let it continue charging for the next 30 or 45 minutes for long lasting uses.

QUOTE(dvlzplayground @ Oct 13 2010, 10:06 PM) u guys ask a lot about charging battery... if someone say u need to charge X hours and cannot charge when not full etc...would u really follow? Ok, thanx for the answer.juz charge whenever it's convenient to charge, and stop charging whenever u need to stop. if u hv to go out but ur phone is still charging at 98%, dun wait for it, juz unplug and go. as katnl have mentioned, heat and empty drain is ur worst enemy.  |
