Yes, since I upgraded yesterday, I have been on a constant battery drain, 2 - 3 hours to full drain. and recharging seems to be a problem now too. I use the GO Launcher and battery info widget and GO Taskmanager. the battery widget and task manager show my CPU maxed at 100% constantly for both cores. (someone tell me how to take and send a screen shot and I'll show you. ) Also the temp stays in the 107 to 115 range and is SUPER hot when I charge. Half the app and widget short cuts don't work either.
