I going to share my opinions and review about this lovely smartphone . I am using this smartphone since 2 year. According to me mi max 2 is cool and best smartphone under 15000. It has big battery life with the 5300 mah battery. That smartphone gives battery backup about to 2-3 days. It has best sound quality. Camera is about 12 MP rear and 8 MP front camera which is enough for the photography. This device also supports fast charging. I thik it takes one and half hour to complete 100 % battery. It also supports Volte. If the size of the smartphone does not matter for you then mi max 2 is the best smartphone ever for you. I think you are going to love it.
