Lately my battery doesnt charge well, it actually charges faster in 45-50 minutes and of course it DEPLETES faster , i know u can type some commands in the terminal to "recalibrate" the battery , can someone post the instructions?

I have never heard of this....

Just try letting your battery completely drain (to the point where the phone turns off... the battery won't be fully discharged but that's fine/a good thing). Then recharge to full. That's more to "calibrate" the battery indicator on the phone but it might help.
How long are you getting out of a full charge anyway and what setup are you running?

Fully charge the battery, then wait an extra half hour. Delete /data/system/batterystats.bin. Use phone as normal.

Delete /data/system/batterystats.bin What app do i do this with or is it done through terminal emulator? will this recalibrate my battery stat?

i to would like to get more info on this

Root explorer or terminal emulator will work. You can also do this through the advanced section of clockwork recovery

Thx! I got it done.
