Hi, my device (mi2s 32gb 3.8.16 multilang) sometimes reboots itself and I find my phone on the "insert PIN" screen......And I notice a 3-4% loss of the battery . It happens randomly and I don't know why (sometimes twice a day, sometimes once a week). It happened also in previous version of miui multilang I put on it. I tried to change the performance battery but it doesn't seem to influence the problem because it happens again. I already did all kind of wipe....in default recovery. Thanks in advance.
