tbh, since the jb release, I'm having a hard time deciding which phone to buy. Gnex suddenly seems so much more attractive 😛On a more serious note, after I updated a friend's phone (manually) with jb, the battery life plummeted . Gives a max of eight hours on a single charge with moderate usage. I've calibrated the battery again, but to no avail 🙁Do report back on the battery life with jelly bean 🙂
