I know it's a bit after the fact, but so every one knows bump charging is bad for your battery, and over time will do serious damage to your battery. It should work with any Li-ion battery just based on the technology, but save it for long days away from the charger.
If you use an after market launcher, load up your stock launcher, remove all of the self-updating widgets, switch to your other launcher, and close the stock one with a task manager or settings>applications>manage applications>twlauncher>force stop.
If you've followed the other sugestions, and haven't seen any improvement start uninstalling apps and see what happens. Try switching one widget for a comparable one, etc. That and watch for poor reception anywhere you spend lots of time. Being in low service areas is really hard on battery over long periods.
