Common Problems

check the installation guide [Installing LX in a Nutshell](Installing LX in a Nutshell)
and try fastboot erase system + userdata

make sure you flashed the right ROM .zip for your device
make sure the ROM download is complete and the .zip is not corrupted
did you flash the kernel (boot.img) from the ROM? Other kernels are not supported.
did you really extract boot.img from the .zip you installed last, and flash it with fastboot?
You cannot run a kernel from an older build. You must flash the kernel every time you flash a new ROM.

±10% drain per hour is usually caused by something keeping the CPU awake ("wakelock"). Usual suspects:

WiFi
Try Settings > Wifi > Advanced > Keep Wifi on during sleep : never
GPS
Better do not turn off GPS manually; or reboot after turning off. It works better if GPS turns itself off when no app uses it.
Bluetooth Often changes. If you have a problem, the only 100% sure way is to reboot after using bluetooth.
Google Location Services
Set Settings > Accounts/Google > Location settings : off and see if it solves the battery drain
Change GPS/Wifi in Settings > Location access and see what happens
Bad apps
If the built-in battery tool does not help you find it, try the BetterBatteryStats (BBS) app. The following two links can help you find the source of your battery problems:
- How to Find the Root Cause of Your Android Battery Problems, How-To Geek
- [GUIDE] The Total Newb's Guide to Wakelocks, XDA-Developers
3G data often results in higher drain than 2G, but this is not as bad as wakelocks.

use Settings > Apps to move apps to the SD card
use the Link2sd app to move more files to SD
