I'm used to 20 days from the mobile. Very good performance. The software is very powerful. It is not too hot on the heavy-heavy games and would not hang. The camera is okay, but not quality. Excellent fingerprint sensor works, we can lock the app also. The mobile has a good texture. What to say of the battery performance, the best performance I've seen in smartphones before. The phone can not get a better price. miui its beauty is great. Everything is perfect to leave the camera in it. Its metal body increases its strength. At such a low price can not get a better mobile.
