Battery drain very fast. Max % use of battery contact storage. As visit samsung store very poor resonance getting from representative. her attitude towards customer was very negative. Beside provide solution she told me that it's all new phone have battery backup only 5 hours hence you have to charge after 5 hours. It's horrible for me.
The best thing to overcome draining issue is GO TO SETTINGS > APPS > GOOGLE PLAY SERVICES > PERMISSIONS > CONTACTS ( DON'T ALLOW). CONTACT STORAGE is draning battery from here.
