This is it. The only working method I've used to get all day..even multiple day battery life out of my incredible.
The secret? Long hold the power button and turn the Mobile network OFF (the bottom option)
When I went on a camping trip recently my phone would die on me in 5 hours, the next day i turned my mobile network off and i got a whole day of phone service with 28% left on the next morning! I would just turn it back on whenever I needed to use the internet throughout the day.
So if you are sitting at work for long hours and not using your phone it would be a good idea to shut off the mobile web, you will save tons of battery life. You can turn it back on easily whenever you need to use the internet and if you plan on not using the phone for a long while just leave it off. You can still make and receive calls just fine but your phone wont constantly be connecting to the mobile network and draining battery juice throughout the day.
