My battery life is horrendous. I had 95% battery life this morning, then I was on Windows central forum for about 7 minutes. After that my battery life was at 49%. Since the W10 install I've had to charge my phone at least 3-4 times daily. I have attempted the roll back procedure, but I get the "USB device isn't recognized" error. I've tried every way possible to fix this so I can rollback my device. The other small bugs like not having OneNote I can live with, but the battery drain is awful. Even when my phone is not in use the power drain is dreadful. Anyone else experiencing this?
