Just recently my battery has started draining more than usual. I'm not doing anything different, and I have also removed a load of apps that I no longer use. I never have my wi-fi on unless I need it, and my screen brightness is always at the lowest setting, but when I check battery usage in settings, "Display" is usually between 41-45%, which for me seems a bit high. Dialer is at 29%, Phone Idle 11% I've also been getting the odd crash recently, and sometimes the phone randomly restarts itself. I also get an instant error in the mail program if I try and move an email to another folder, and mail program just crashes. Roll on June when I can get a new phone!!!
