I've had the Incredible for about a month now. I don't use it to talk very much during the day and run minimal apps on it. I use the app killer to make sure nothing runs in background. Just sitting on my desk with very minimal use, the battery will only last from 7am to 5pm on a full charge from the night before.
The battery life is pretty similar to my analog Motorola StarTac circa 1997. It really is pathetic. Anyone have a suggestion? Is there a better battery to buy and put in this thing?
