Battery life is very good in these phone due to large 4100mAh battery as compare to other smartphone these phone battery is twice, fingerprint scanner is also work very well it quickly unlock the phone when you tab the finger on scanner. IR Blaster also very interesting feature and work very good I mostly use these feature for controlling TV or tatasky. General Day to Day performance of these device was excellent there is no lackness. Also I was very surprised in gaming performance all heavy game play perfectly even in high graphics there is no frame drow when I play heavy games.also there is no issue of heating when you play game or using browser .all sensor work very well. Rear camera is good when you shoot in good light but when you shot in low light you have to struggle to take good photo, selfie camera is good in the price section.i only have one issue with these device which is speaker sound .ringtone notification is very low I miss may call due to these issue
