Are you a Windows Phone 7 owner, frustrated with the inaccuracy with the battery indicator? If so, then XDA forum member arkatis‘s thread on fixing this is a must read.
The fix involves a registry tweak to Local machine/system/state/batteryux/MainIntervalIndex from the default value to ’20′, and then again to ’80′. You’ll need to restart your mobile device and also charge it.
Here are the actual instructions:
1) Charge your phone until the green light shows up
2) Unplug it from A/C and open registry editor
3) Go to the reg path
4) Edit the value from 6 to 20…press ok..Now you will see the battery indicator level has been changed! Again go and edit the value and from 20 go to 80..press ok! Restart and enjoy!
Members who have applied the tweak, have reported that it sticks. However, why not see for yourself?
