| | Re: Has new OS killed battery?
The most common cause of real short battery life (with a known good battery and no other useage type explanation) is probably data apps left running and that are repeatedly hitting the network for updates. But you say nothing is different except the OS upgrade, and use is the same. Still, you might want to double check. Pay paticular attention to apps that are set to run in the background when closed instead of fully exiting. Maybe there is an app (IM, facebook, twitter....) that was set to exit before and somehow it is now set to run in the background.
Another possibility is that just by coincidence the battery happened to start failing at the same time you did the upgrade. If you can borrow a battery for a test, that would be the thing to do. Or else take the chance and buy a battery.
