The rest of my update seems fine but battery drain is ridiculous. I'm at 70% this morning after only 2 hours of moderate use...and no calls. Prior to update I would expect to be at 95% at worst. Any fix for this? Wishing I didn't do upgrade already. Thanks !
Go into settings, battery, battery usage and see what app is taking up all of the battery. If there is an app you installed that takes most of the battery, try uninstalling and re-installing. If that doesn't help, try doing a factory reset which will wipe your phone back to like you got it from the store but with lollipop. That should definitely fix it.
