Problem after upgrading to Lumia denim

[pock8]

My battery pro has detected one app called 360 follow by the Chinese words... This app are made my battery power drained out.. When I try to disabled it's running background then I just realized that the app are not in my app folder... Until now I'm having a problem of run out of my power faster.. What should I do to resolve this matter.? And how to kick it this app from my phone.. I'm using Lumia 1520.. Ty for any feedback..

Do u have Camera 360 app? Probably the culprit behind this. And do u see it with battery sense tile?
If nothing works out a Hard Reset should definitely fix all ur issues.

I already did a hard reset.. But my battery run out so fast compared before denim update but more better than before hard reset... Do you use denim version right now and what do you think bout it?I mean the battery..

Well my 620 didn't have any firmware updates with denim like the 1520 so it can't really be compared :/
