jbsangel - it's difficult to estimate time when your usage varies to the extremes.. ie if you leave it for 8 hours doing nothing, then run streaming video over wifi with the volume and brightness full. i could show reported battery % but have to be careful not to confuse people (ie they need to know what they're looking at). Could add in a button for the battery history easily enough, not sure what you mean by battery usage? Also easy enough to add in system uptime and last unplugged time.
Thanks for the feedback. I understand the bit about usage varying to the extremes, that is why I'm not surprised when I see the app severely underrating the percent left after my phone has been idle for longer than normal. Your app is very useful for me for gauging my battery life.
I'm up to 84% accurate and as long as use my phone "normally" it is pretty much dead on.
As for the battery usage, I'm talking about the screen that shows the actual device usage: % running, %screen on, % BT on, %wifi On, %wifi running, and has different choices you can select to see, among other things, partial wake usage. This is internal to the phone, but there is no link in the settings to get to it. Apps like spare parts and better cut provide links to see the screen, and the battery status widget app also links to this screen. This screen is very useful for gauging usage.
Nice to see you hanging out here and listening to the feedback. Looking forward to any of my suggestions that you might implement.
