My Xiaomi Mi5 won't power on after 2 months of use. My friend's Mi5 won't power on after less than a year. It seems it's a common problem: google "Xiaomi Sudden Death". For warranty I have to ship it to China, which I knew when I bought it so I'm not complaining, just not recommending Xiaomi in light of the "sudden death" issue.
