M currently using the phone mi 4 32gb black variant .To be honest the phone is super cool when comes to battery life charge it once 100% n u don’t need it to plug your charger again with all the internet n game usage . I m recently playing world of tank blitz which is a 3gb game it works fine just some temperature rise issues while playing game but totally smooth game play cam quality good speaker quality good finger print response is good n quick overall this is a perfect budget phone to buy totally worth every penny u spend to buy it .
