I have a galaxy nexus just bought it, and the battery is horrible!! Any suggestions?
If you don't mind a little bulk take a look at the Seidio 3800 battery. I usually average 12 to 15 hours with highly than normal moderate use and close to 32 hours with light use. You have to follow the conditioning recommendations to the letter (in my experience) for the first few cycles. It is a little pricey, though. Also, I do limit what is snyching in the background and keep the backlight down to half more or less. Oh, and I keep it on WiFi as much as possible.
