Whenever I'm having issues w/ my G2's battery life:
Charge phone to 100% capacity . Then, with phone still plugged in, hold power button down and select "Power Off and Restart". Let the phone do it's thing, then you're good to go! Make sure you leave it plugged in while you restart it.
I think if you let your battery get too low, it can kind of forget where 100% charge is (cause the battery is designed to stop charging once it's at 100%.) So by charging it all the day and restarting it, I think it helps the battery re-learn where fully charged is.
Hope this helps! Has worked for me every time.
