**Tip for battery calibration**

So you can't actually calibrate your battery in the file system. You can, however, "reset" the file that's used as the "brain" for how Android uses and reports the battery life, for lack of a better word. The file is batterystats.bin and the location is /data/system/ - it's been that location on every Android phone I've owned. If you delete or rename this file, the OS regenerates it upon reboot. Therefore, to get the cleanest start possible, or the cleanest calibration possible, on the final reboot in your calibration, go in and rename the file to batterystats.bin.bak (or delete it) right before you reboot. Do this once you know you'll be using your phone in a "normal" fashion on a day to day basis. That way, your battery will be fully calibrated, and this file will be reading/reporting based on normal usage and a fully calibrated battery. I can't attest to this, but I've read before that it's a good idea to clear this file out on a regular basis anyway (every few months or so).
