Yes battery is very impressive with mpdecision removed. Unfortunately I'm still getting reboots. For partial_wake_lock, if anyone is experienced with coding simple apps this is all we basically need: https://developer.android.com/training/scheduling/wakelock.html#cpu

Got another reboot a few hours later. These frequent reboots are worrying me I hope it's not an unfixable hardware issue. I will try wake lock with mpdecision removed since it has better battery this way.

Update: phone rebooted right before my eyes on the table sleeping with mpdecision removed and thermal tweak. :( I still can't get the partitioning thing out of my head. I'm thinking wake lock app in a way prevents the phone to do some sort of caching/storing, kind of keeping the phone awake...

@jc rey I haven't tried the wake lock app yet. I'm first trying different scenarios to maybe get an idea of what's going on. It's a shame it's not my phone because I would be way further with tests. :P Anyway gf says that battery is the best so far with mpdecision removed and also noticed...

Well sad to report phone rebooted during the night. Lately phone reboots almost on a 24 hour cycle (sometimes twice), usually it took longer to reboot when trying different tests. I guess judging by this mpdecision has no bearing on reboots, at least in my case. By process of elimination I'm...

Yes I noticed the cpu0 parameters and I was wondering why. I thought the battery monitor parameters were readded with Miui 8? I know they were present in KK Miui 7.1 and omitted later in MM 7.x for some reason. The temperature seems fine now to me although it might possibly get very hot under...

Just deleted mpdecision myself but left the original thermal conf for testing. Indeed all 4 cores are always active lowest frequency at 300mhz, cpu load is minimal because all are active, personally I think this is why battery drain is less. I'm not sure about the temperature of the phone yet...

I think it's only disabled for Mi5 and perhaps some other models.

Usually android kernels have their own cpu regulators and governor settings while mpdecision is for Qualcomm chips and nullifies the kernel's settings, so maybe these two (in Mi4's case) don't exactly get along. Perhaps Miui's MM kernel doesn't "allow" it to function properly, so by removing...

Only 1 core active with mpdecision removed or with 6.9.20? I'm going to try removing it tomorrow to see what happens, if reboot happens then I'm going to try sMiui's mpdecision.

Update, had a reboot with KK's mpdecision and thermal, so that's that with this test, unless clearing cache is necessary? My short experience with sMiui wasn't pleasant to be honest but it is tweaked a lot like all 4 cores active and auto rotation working and other stuff. Maybe I can try...

Also cpu load is much lower, which in my opinion makes sense that less battery is used. This is nothing new we have been speculating about this many many posts back, just never tried removing or replacing mpdecision. My best guess would be that they put 2 cores on OnDemand governor (or some...

The KK thermal is the same as MM thermal from what I see but with added battery monitor synthax. But this this was reintroduced back with miui 8. In 7.5 it wasn't there. KK thermal-engine-8974.conf sampling 5000 [CPU0_MONITOR] algo_type monitor sensor cpu0 sampling...

Quick update, with KK's mpdecision all 4 cores active/standby, cpu load is good and battery temp is good. I also uploaded KK's thermald-8974.conf file which is not present otherwise in MM. So far phone stable.

@zegio In twrp you have to mount system under mount settings then you can remove copy edit etc. the files in /system. You can also do everything via adb shell too.

@jc rey Good idea. I'm going to try KK's mpdecision and thermal conf for testing.

No, nothing in particular. But perhaps this way it would be possible to get more ideas. I'm guessing the miui battery saver also goes to work when phone goes to sleep? I was thinking of uninstalling/deleting the powerkeeper apk maybe. @Applepie2 Personally I only tried sMiui 8.0.2 but I found...

Anyone tried the wakelock detector app to see what processes are waking the device up?

On my side I now tried sMiui. I erased everything again with fastboot and additionally erased everything in /dev/block through adb shell so I think it's as clean as it can be, then emergency flashed 8.0.2 china stable, then complete wipe in twrp and sMiui 8.0.2 stable over it. Happy to report...

@zegio Are you running 8.0.2 official or .eu?
