Dear MI,
It is for you information that I m using your phone last 10 days and observe the following issue.
It takes 5 to 6 Hour to charge 100%
Voice quality is very bad always singal break at the time of calling.
Screen pixel is too bad with your commitment i.e 401ppi my asus zenfone 2 laser has only 267 ppi but this is better than your? 401 ppi
At the time of charging its gonna heat up like iron, you can boil water with this phone.
