Bought the 32 GB version 4days ago. Using the whole day. Battery backup is awesome. Played Asphalt, Fifa, Real racing, Mortal Combat. It heats up but never lags. Heating isn’t an issue at all. Updated the phone to the lastest one 1 day after I bought it. I felt that heating issue was reduced somewhat.
If you want a flagship phone at the price of a midrange one . go for it.
The camera is mindblowing. Absolutely love the camera. Also the sound and display quality. Battery backup is very good. Turbo charging works wonders.
A tip: Buy a backcover. It makes the phone cooler. Also install Pi Music software and turn bass boost into max and equalizer preset into Rock. Thus headphone experience become awesome.
