1. Battery draining has been reduced. But not completely.
2. Heating has been greatly removed. I played Asphalt 9 for 1.5 hours, it was getting warm only not overheated.
3. Fingerprint has been made more accurate and smooth but no change in speed.
Note: Users who are facing problem in registering fingerprint should remove the screen protector then attempt again. It is not getting registered because your screen protectors must have got some scratches over the fingerprint area.
