Ive been using this phone since a month ago, andIts unexpectedly amazing especially for something as cheap as this.The battery life is extraordinary, I used this phonemainly for playing games and reading books for hours and I ended up only charging this phone only once in 20ish hours. The performance from high end games were not lagging as well. It neverreally overheat either, and if it does gain some heat after playing game for longer than a hour, the temperature always went down fast. I assume its due to the metallic case on the back and I always put the phone on the floor to cool it down if it ever get warm. LOL(Love your battery by always letting it cool)The sensitivity from the finger scan has a very fastrespond, but since it updates to MIUI 8 theres a minor bug that will make you have to lock and unlocked before you could double scan your finger if you left your phone in a locked app. But since the respond is really fast I never really mind.Multi tasking is really easy too, I rarely experienced any lags from jumping from one app to another. Listening to music through speaker orearphones have been very pleasant too.Now lets talk about the downside from this phone which actually had never been a big deal for me.The camera is okay, not really great but not disappointing either. They have some features in it which help a little bit for your result but then again it doesnt really help much. Lastly I personally think the phone is naturally slippery, but this could be resolved by just buying an phone case right?So thats my review for this phone, overall Im very satisfied with it and I guess it will take a longtime for me to change into a new phone.
