Best ever phone at ?9, 999. price range.Battery backup is good. It lasts for 2 days for average usage. And also it doesn’t get heat at all. Maximum it goes to 40degrees while heavy usage.And those who are facing jio volte issue, sim works on both sim slots without any problem. Initially u will get HD symbol at signal bar. After updating to MIUI8 u must reset the phone. Then u will get VoLTE at signal bar. For better working of phone keep phone updated. I was really satisfied with this phone
