The mm-qcamera-daemon problem with Android 4.4.2 has been widely reported, and several manufacturers have issued fixes. Is there a fix available for the Hisense HS-X1?
So, your camera drains your battery?
Probably some apps are keeping your camera on, try killing background processes with apps or manually. You need to find out the app which does that.
In the battery options, it might show which app is draining?
I hope it helped.
