As I put in a thread previous, my battery seems to be the wonder battery. For normal use its usually lasts around 1.5 days before it starts to get low (Which browsing/games/wifi on etc). On some work days with low/normal use its reached over 2 days still with about 20% ish left!
I must have the only Nexus 4 device that seems to work how Google meant it to! My battery is fine, with normal use it usually lasts 1day and a half. With low/medium use while at work etc I have got it to 2days 10 hours with 30%ish still remaining!
