We use LiION Batteries, No special charging required
OK, to start, there is NO NEED to do any special charging conditions with Li Ion batteries, it does not matter how they are charged. A standard battery will have between 400 and 1200 charge cycles before it loses 50% of its capacity (1200 if you charge at 50%, 400 if you charge at 0-10%, like when the phone quits on you). Ni Cadmium on the other hand does require special charging situations but we don't use them in cell phones because of the mass. You can do take the advice of the previous post, but if you do that I would suggest sacrificing a virgin symbian phone or doing a handstand while plugging in your phone to charge. That might increase the battery life too.
Secondly, I spoke with Verizon, and their 2100 mA extended battery will be available soon and it is supposed to fit with the stock backing, probably the best way to go if you ask me, only $60 too. I am checking their site almost daily waiting for this to become available since like many, I need more battery life, I find that I can barely make it through the day without being conservative with the use, and that's on a work day when I'm not on it that much, on the weekends I have to charge it in the afternoon.
If you want to save on battery, turn down the screen brightness, chose a background with as few colors as possible, the more black the less battery you will use since its an AMOLED, blacks mean there is no power being used on the screen. Turn off your GEO locations services both on the phone settings and in programs that run a lot. This will easily save you 25-30% battery life.
