My Google Nexus S battery drains after updating from 2.3.7 to 4.2.2, even if it is turned off. One night I shut it off at 70% charge, and when I turned it on in the morning it was at 9 or 10%. I bought a new battery but it has the same problem. What should I do?

You should calibrate your battery:
- Fully discharge your phone
- Fully charge it when it is turned off
- Disconnect charger and wait a minute
- Connect it again and turn your phone on
- Delete your data/system/batterystats.bin file (with battery calibration for instance)
- Reboot your device and disconnect charger
Also, it is common problem, so try to google it yourself
Hope this will solve it for you
