Mi comes up with new ideas, and is now well known company in india, xiaomi products are durable I have been using xiaomi product from the launch of Mi3.
Mi max is a great budget device.
Performance 9/10- Sanpdragon 652 performs well on max, no lags whatsoever u play on this device.
SCREEN ON TIME( SOT) - 7.5-8.5 HRS
Battery Backup 10/10- 1-2 days on the basis of usage!
Multitasking 10/10- 3gb ram is enough to handle all the application.
UI 8/10- Has a great customizable UI, but as we all know miui is a bit heavy.
Camera 7/10- Not upto the mark but good in this price segment.
Pros.- Quick Charge. Battery Backup Performance
Cons.- A really large display 6 would be enough.
