This device is really powerfull. I have been using this device for around six months and I have no issues.the battery life on this device is very long due to its huge 4000mah massive battery.perfect miui.got proper updates.camera is little bit disappointing but when it comes to price it is the best budget device under 12k.it has a snapdragon 650 processor which is very good and 16 mp rear camera and 5 mp front facing camera. Also it performs good when it comes to gaming. There is no heating issues. If performance is your first priority.then go for this device ??
