Re: VZW Septemb update killing my battery
Try doing a cache partition wipe. Turn off your phone. Then simultaneously press on the volume up button, the power button, and the home button until you see blue writing at the top left corner and an android character appear. Once the boot menu loads, use the volume down button to select wipe cache Partition and select using the power button. Then use the volume button again to yes and power button to select it. Then hit power button again to select reboot phone. That should fix it. I do this every time I update my phone. Give the phone about a day to get back to normal usually does so after a full charge.
