Hi,
I'm using s4 mini LTE I9195 with CM11 M6, f4ktion 1.4.0 kernel, BN3 modem, TWRP 2.7 recovery
All was working fine, average battery drain on idle was 1%-2% (not great, but fine), and suddenly it rocketed to drain 15%-30% per hour.
I usually use Android Tuner's battery measure stats to track drain statistics over time.
After checking it, I"ve noticed that it () the drain) started in the middle of the night.
So it's not due to "I launched this App, and then..." It just went nuts on it's own...
I've checked which process is to blame and the first one with max battery consumption is:
com.android.systemui (with KitKat logo) followed by Android System, then Screen, and then all the usuals.
I tried to do reboots, disable wifi/nfc/rotation/data/sync/anything else/kill user apps - no effect ...
It still drains about 20% per hour on system and systemui for the whole day now :crying:
And I have no idea what causing it / how to revert it...
So, do you have any suggestions on how to trace this bug?
What to search for in logs?
Any thing else?
I'm not a big pro on android OS subsystem, so advises are welcomed!
I'd love to help, but I actually stumbled upon this thread while googling to help myself
I'm using Note 2 (N7100), running CM11 - newest nightly (although I flashed it today, after slightly recharging the battery once I noticed the problem) and Devil3 kernel.
I'm having the same issue - yesterday everything was fine, I've left the phone to charge over night and display time as usual and in the morning nothing seemed out of the ordinary, until 6 hours later. After those 6 hours my battery was fully depleted (whereas normally lasts whole day and is not even close to being depleted). com.android.systemui and Android System seem to be the problem for me too.
I've also tried turning off some functions, uninstalling some apps, turning off notification privileges for others. Even, as said earlier, flashed newest nightly. Nothing helped. Using phone with without flashing Devil3 kernel didn't help.
Anyone have any ideas?
Just try to flash stock software and again CM.
Try a older version of CM11, and if stability is a priorty stay on CM 10.2
OK, so I've tried a few things, and had a few surprising outcomes:
I've analyzed the CPU load with various tools, as Android Tuner, OS Monitor, and All-In-One Toolbox.
Most of them reported Android System using 30% CPU, and com.android.systemui using 25% CPU, all on the highest frequency.
But All-In-One Toolbox recognized top process instead of Android System as Lockscreen android process, so maybe there is a hint there...
(and I don't use any custom lockscreen stuff beyond stock CM's one)
So, backed up the current troublesome system (let's call it BKP_NEW), just in case, and decided to restore a full NANDroid backup I had from a week ago (and the issue is just from yesterday).
Restored all 6 partitions (/system, /boot, /cache, /efs, /modem, /data), rebooted, and....
...The issue was still present! Crazy battery drain just as before!
Very confusing... Then I went for a factory reset - it fixed the issue, but I have to start from scratch with all the SW installs and config, and I don't have a week to waste setting everything up again, and potentially running into the same issue some time later.
So, I've decided to move further back, and restored a two week old NANDroid backup > reboot > No issue presents
But it was just too weird, since the delta between 1-week old and 2-week old backup is infinitesimal.
So, out of curiosity I've decided to restore the BKP_NEW (the one of the system with the issue present)... and after the restore it works just fine! (WTF?!?!)
After thinking on it for a while, my conclusion is that there was some problem with some part of system that was wiped/fixed in TWRP's Factory Reset, but is not touched/overwritten during the NANDroid 6-partition restore.
But again, this is just my assumption, need someone more knowledgeable to confirm this possibility...
(maybe @ne0zone75 can advice on this?)
Since that, all is working fine (at least so far).
And if my assumptions are correct, @Ksenios, you can try to do this, and still have working system with all apps and configs (If youre comfortable with recovery / backups management).
hi,
(passing bye from google - just a note)
com.android.systemui cpu high usage (about 37%),
on my huawei media pad x2 (gem702l) but only while charging (and just sometimes), if that gives something for someone, any clues why ?
Hello. I can't unlock my phone smooth on android 5.x and 6.x (after pressing power button i have to wait 10s+ until screen will wake up), because it doesn't go into deep sleep mode and just working @lowest set frequency . I've tried few roms (e.g. resurrection, nitrogen, aosp, cm...) few kernels (e.g. nitrogenex), fev cpu governors and everytime i had the same problem, even on clean rom, after wiping and configuring only google account without restoring apps, without location, wifi, data etc. I gave up with it some time ago, but now i tried again, new release of resurrection and decided to ask you for help. On stock 4.4.2 it's fine, unlocking instantly, and going into deep sleep normal, but i wanted to get newer android What do you think, is NFC may causing this problem? Because probably i've got broken chip or something, because i can't even turn on nfc, doesn't matter what rom, stock or custom.
Thank for answer
i have htc 10 with stock firmware without root

AKT does not work without root . Also if you have flashed another rom then use root and then install BBS to check whats keep your device awake .
Install batterbatterystats whats keeping device awke and stop wake lock by deleting app or stop other wakelocks using ex kernel manager

Hi there, did you manage to solve your deep sleep problem?
I've had this problem. motherboard replacement done but problem not solved. technical service device changed. solved
Hi to all.
I know this tablet is old and with few support but suddenly (I guess just a few months ago) started having a kernel wakelock (sec-battery-monitor) that doesn't allow my Tab S (8.4, T700) to enter into deep sleep.
I use BetterBatteryStats to see the wakelocks.
The Tab S is rooted with latest Magisk (18.1) running debloated Stock marshmallow.
I tried different combinations of software but can't find this issue culprit.
Anyone else is having this problem or had it in the past and found a solution?
Thanks in advance!
Since the last few updates, even on a fresh install with nothing installed. My LineageOS in Alioth has been using 7% to 11% /hr of battery. Tried doing a clean install, reset to factory, even tried reseting battery stats. Sadly cant do anything about it and I'm not being able to go back to versions I knew worked OK (19.1-20220723 for example since i dont have an img to use and lineage page only have the latest). Not sure what else to do and really don't want to go back to MIUI.

Has it improved in the meantime?

Had to roll back to a previous image and stop it from doing auto updates.
I'm on the latest LineageOS release on two F3 devices. I think it can use 7-11% per hour or more with screen and WiFi on. If those numbers are for an idle phone, it seems way too much. I get maybe 1% per hour if the phone just lies down. Maybe less with WiFi off.
