Battery: for normal usage it can last for a day and for hard core browsing and gaming will only last it for 3 hrs at max.
Processor and GPU: it is quite a decent one I would say, it wouldn’t allow very hard core gaming but will ensure least lags less app crashes. Seriously guys, it sticks at gaming
Display: this thing really amazed me, display is bright it is a ipc panel but the brightness it showed up in boot can clearly tell you how brought it is.
OS: Dude that is even worst thing ever seen on any mobile, I would recommend anyone owning this device to use some really good launchers. CM Launder worked like charm for me.
That wraps it up guy, overall a good phone with quite a good things for the money you put over a mobile. Also, it has gestures enabled and are totally customizable works great.
