probably this would be your solutions...



ok, back to your battery drain issue

If your ZR is rooted, i highly recommend you to install this app called App Ops, it's an permission managing app. Disable the keep awake option under the Google Play Service.




If your ZR is non rooted, sorry I can't advice further...

Mine just disabled the location service. Since then no battery drain issue..

60%??? thats alot! 

60%??? thats alot! 

try updating and resetting your phone. sometimes mine also suddenly cant detect any touch, but after lock/unlock screen or activating camera from lock screen via shutter button and back again will make the screen back to normal

Your case still not consider the worse tho
My dad's iPhone 5 repaired four time within one year
first time is power button hard to be detect during press within few months
then go digi there repair (since he bundle with digi plan), then after repair back found that microphone received sound is too low volume, repaired for second time
then found that battery is too fast to discharging, repaired for third time
After bring back and use for one months ++, the phone is start to quick show battery 1% and shutdowm while the battery level is still got 30%++. initially still ok can open back, after few time the phone is refuse to open back and even charging, even I tried to go inside recovery mode and restore also can't, now digi is refuse to repair, so no choice my dad repair at his friend shop.

My ZR have no problem so far
