Just a note to all rooters: in case your battery drains too fast after rooting, try the following:
1.) Connect charger
2.) Use Root Explorer to delete /data/system/batterystats.bin
3.) Power of and let the unit charge over night
From now on, the battery will be re-calibrated... may take 2 or 3 charge cycles...
In general it is better to flash the T1 with a fully charged battery only.
Also, there is an app that automatically shuts down unwanted processes when switching to stand by: http://www.androidpit.com/en/android...d-Task-Manager
...may help conserving battery because some apps are able to wake up the device and so some stuff (check for updates, etc.)
