Using this for almost 4 years. Broken screen, Lot of drops, Hard gaming but still works fine.
The RAM is 4G which is very good. The camera is average. Looks cool and stylish. lightweight.
Battery stands for 24hrs even after 3 hours of gaming.
It look nearly 3 hrs to full charge. No fast charging.
MIUI is soo cool and very user friendly. Lot of customization can be done with MI.
I Love it.
