    It is in your build.prop. Im using 8.1.3.0 China Stable, ill show u how to fix this reboot issue (root access required):

    - delete 'mpdecision' file from /system/bin

    - replace thermal Conf file in /system/etc by this one, then grant it access as the previous one
    //cloud.tapatalk.com/s/57dfe313e1118/thermal-engine-8974.conf.zip

    - open build.prop in /system, find and change the line 'persist.cne.feature'=1 to 0, then reboot to recovery and wipe cache/dalvik.

    Or before flashing a rom, u can use WinRar to open the rom.zip, and modify files above (delete/replace/edit the following files) then flash this rom. Very easy now my fone runs smoothly.

    THANKS to @jc rey hheeeee.

    For me haven't random reboots. I clean install full rom via fastboot, and get it, but for me annoying core cpu bug, about 2 cores work only.
    I delete mpdecision too and replace thermal conf. This is work fine now.

    Indeed, I agree that installing with twrp seems to cause some more reboot.
    For the random reboot test, how long do you let the install go ? it requires at least 2/3 weeks with no reboot to conclude imho.
    And the fact is that fastboot install is fine with global official rom, but xiaomi.eu requires twrp.

    yes agree ;)
    The problem is that we cannot retest all assumptions in parallel.

    If you delete mpdecision, are all 4 cores always on? Are you facing always better temp/battery life without it?

    the fact is that probably the chip consumes less power using 4 cores at middle range frequency that using 2 cores at higher cadence.

    This morning - random reboot, Xiaomi.eu 7.2.16 latest developer rom, mpdecision removed, thermal conf file replaced, battery status around 90%, the Mi4W restarted and during restart the white line under mi logo appeared. I was waiting for about 7-10 minutes for the white line to complete?!

    I can't believe it!
    For over two months now I didn't have any reboots, ever since I update to global official rom 8.0.3.0 and to the roms that came after that.
    But this weekend I updated to 8.2.1.0, and already had 2 random reboots since then!
    Did they fix the issue and then un-fixed it again?!
