Sudden reboot

[ibrido8]

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.

I just got my Mi2S on Monday and since then it has been doing these weird reboots. It's the same story here, somedays it happens a few times and other days none. Any help would be greatly appreciated.

My friend's mi2s 16gb, using last week's multilanguage rom, does that as well. He just received it last week. Could it be a defective batch?

The same for me (32GB, VODAFONE, Hungary).
It seems like that it happens when the network switches from 3G to 2G and back... Now I use my phone allways on 2G and just turn 3G on if I really need it, it helped a lot, but I don't think it should work like this!

Have same problem on my new mi2s 32gb. Rebooting all the time. Some times just wakeing up and restarting. But what i found out is: when phone is charging is never happening. Think about bad battery. Tomorrow will test on different battery and let you know guys.
