I recently noticed that my rooted T1 is using more battery power than normal and thought that a recalibration is in order. By going to the rooted T1 wiki page, I found the following:

Battery Gauge Recalibration
If you experience short battery life after a rooting / firmware upgrade, it might become necessary to recalibrate the battery meter. In general it is better to flash the T1 with a fully charged battery only.
The key is to make the device forget about all battery stats and have the battery stats re-calibrated with a freshly charged battery.

Connect charger and charge to 100%
Delete /data/system/batterystats.bin (e.g. via Root Explorer or BatteryCalibration App)
Press the reset button instantly after deleting batterystats.bin. This will prevent batterystats.bin from being recreated from data in stored RAM. If you miss this step, or simply power down the device instead of a true reset, batterystats.bin will be restored automatically by the system.

From now on, the battery will be re-calibrated... may take 2 or 3 charge cycles...
Alternatively you can use recovery console to delete batterystats.bin

QUESTIONS???
On the T1, I can get into the root explorer - unable to find /data/system/batterystats.bin file and if I did -- how do I delete it? I went to the data then system subfolders

If I want to install the Battery Calibration app - Google did NOT detect the T1 reader and would not download the app. How do I do a workaround?

Is there a way to use a PC connected via USB to the T1 to find and delete the troublesome bin file?

thanks!
