If you're like a lot of Android users, you're obsessed with battery life and probably require a percentage widget. If you don't use a battery life widget, this probably isn't for you. I used to use Curve Fish's battery life widget which, in my initial testing months ago, didn't seem to affect battery life so I kept it and didn't think much about it. My brother-in-law showed me a percentage indication that goes over the battery icon in the status bar on his Evo 4G. I found this hack for the Hero: [PORT] Display Percent Battery Left within Battery Icon - Fresh 2.1.2+ - xda-developers It adds the percentage remaining on top of your existing battery gauge in the status bar. Yes, root is required for this. At the time of writing this, I am at 14h 20m since unplugged and have 69% remaining. I would typically be between 47-53% remaining by this time. That equates to 3.5% drain per hour improved to 2.2% drain per hour. Which then comes out to around 60% increase in battery life without the loss of any features. Hope this helps some of you!
