After this recent update, my battery has been abysmal. I can't get one day out of it, even if I don't touch my phone! I used to get over a day, using it fairly frequently. I started work at 9am today, left my phone in my car (Fully charged) , came back at 11pm when I'd finished, battery was dead, phone was off. Bluetooth - off wifi - off 3G - on. info not really necessary as was phone working fine prior to update. Well, that's all I can think it is, anyway. I do like the update, though.
