About the display using 60%, I consider this a good thing.
Unless your screen is set to super high brightness, it means that there is nothing else (apps, wifi, etc) draining the battery.
Yesterday Sync got stuck trying to update itself, and the usage became 60% for Android OS with Battery down to 20%, leading to my battery lasting only a few hours.
Generally my display usage is 70%, and battery lasts 24 hours.
