[Galaxy S6 Q&A, Help & Troubleshooting] DarkNate34:
I tried investigating even further into this issue (on my S6 without root, haha...) With GSam Battery Monitor app.

And I learnt that 'Android OS' is actually just the Kernel.

Like I originally posted my findings on this thread (if I'm not mistaken). GCM Based apps will cause the battery drain. To be specific, usage of GCM based apps will cause the Kernel to go haywire and start consuming the battery.

Rebooting doesn't help me and Google backup has always been disabled on my phone's.

[Galaxy S6 Q&A, Help & Troubleshooting] meboy:
Rebooting right after unplugging from full charge and disabling/freezing Google backup make no difference to the problem for me.

If those work for you it would be helpful to others to post all the details.

Only disabling WiFi shows a drastic difference for me. But mostly just during sleep.

Something must be set to run when WiFi is on.

Friday, i had some time and did factory reset to my phone. Everything worked well till today, today in afternoon I got battery drain from android OS (backup). So, backup is disabled now. let's see what will be in future.

P.S. the phone disconnected from charger on Saturday morning, draining started after 28 hours.

P.S.S. question who gets battery drain, do you use package disabler pro?
[Galaxy S6 Q&A, Help & Troubleshooting] jaswinky:
I do, but I installed EZ Package disabler after begins battery drain.

Yesterday I had google backup disabled and no drain, but today it started again to drain my battery. Then I enabled again google backup and no drain (!?!!??). I suspect that what really temporary fix the battery drain is not enable/disable google backup or reboot, but just any change on settings involving google play services or something...

[Galaxy S6 Q&A, Help & Troubleshooting] duongla:
I saw the Android System battery drain problem right after the second update of Marshmallow which was a minor one.

For my case, I am sure the reason (may or may not be the root cause) is the Fast cable charging feature which Samsung offered with the update. When fast cable charging is enabled, the Android System drains the most battery and this process stays awake most of the time.

The workaround is as mentioned by some:

1. Fully charge the phone

2. Disable fast cable charging in Settings->Battery

3. Reboot the phone

It's quite annoying to do above steps everday. We have to wait for Sungsung next bug fix update.

---------- Post added at 06:10 PM ---------- Previous post was at 06:03 PM ----------

In my case I can fix it every day by one of this:

1. just rebooting after fully charge (fast charging and Google backup all ways enabled)

2. Disable and then enable again google backup (with no need to reboot) once fully charged

Now I am really sure there is a 3rd way, yours: once fully charged disable and enable again fast charging with no need to reboot... tomorrow I will try this.

My suspect is that it is a MM bug from Samsung, something gets awake and any important change in settings triggers something that resets and temporary fixs the bug symptoms.

Usage of GCM based apps causes 'Android OS' (aka the Kernel) to go crazy on my phone even more than it would without usage of GCM based apps. But nonetheless, the problem exists on my relative's S6 Edge as well, which has no GCM based apps installed.

Hello guys,

Back in february I installed MM from UK (XEU). My phone is NEE so I decided not to wait. All was fine whit overnight battery usage of 2%. I noticed about two weeks ago battery drain from android system. It was some extreme battery usage (750 maH on a 55 % battery). So this monday I flashed the latest XEU firmwate security patch 1 May. First charge after flashing, perfect. Yesterday chardged again an wooow android system gone crazy.

Interesting is that I had no problems for about two months, than suddenly battery drain on older MM. (no updates where installed in that time as I had the wrong product code(NEE) so OTA was OFF.

BTW changing the csc to whatewer u want is working perfectly as I saw some post on another thread.

[Galaxy S6 Q&A, Help & Troubleshooting] Jaqen H'ghar 86:
For the majority of people having Android System battery drain (started with April's update), the cause is the *backup* android system wakelock, which is directly related to Google Backup and it prevents the phone from dozing and entering a deep sleep state..

The *backup* wakelock is activated once you plug your device into the charger and it continues to manifest no matter what you do because it's stuck in a buggy loop, only reboot will fix it temporarily until you charge the phone again.

Through many trial and error experimentation I finally found an easier fix than rebooting every day.

1- Reboot the phone (just once to fix the wakelock, or the next steps won't work if it's already activated)

2- Before charging the phone, turn off WI-Fi & Google Backup

3- Fully charge the phone

4- Unplug the phone

5- Turn Wi-Fi & Google Backup on again

6- ???

7- Profit!

The culprit is Google Backup, and the bug is activated once the device is plugged into the charger and on Wi-Fi, but if it's turned off before and during charging with Wi-Fi off it'll not be activated.

But if the wakelock is already activated, it won't go away even if you turned backup off.

The Wi-Fi is a strange case, I once rebooted the phone, turned backup off and charged the phone with Wi-Fi on and I had the wakelock. My guess is even with backup off, some logs will still try to backup when Wi-Fi is on (Wi-Fi passwords maybe)

4th day without the Android System battery drain and both my Nexus 6P and Galaxy S7 Edge doze properly now.

Hope It'll help you as it helped me.

[Galaxy S6 Q&A, Help & Troubleshooting] Breach1337:
I posted a question, but then found this thread - have the same issue. After reading through all the comments I think people are mixing up the issue of *backup* partial wakelock which happens in Android System and then the Android OS kernel wakelocks. Disabling Google Backup fixed the first problem, but the Android OS awake time is still too high as of the May ROMs.

After looking at the debug log I think one or more of these wakelocks are the problem:

ssp_wake_lock

lli_pm_wlock

ssp_sensorhub_wake_lock

No idea what lli_pm_wlock is about, but the ssp ones are related to Samsung's sensors for humidity, pedometer, etc. This is really strange since I don't think I have any apps which are using those. I tried disabling SHealth, smart stay and the keep display off if in pocket setting, but no difference. Unfortunately until Samsung fix their kernel I don't think there's a good solution here, but happy to hear ideas.
[Galaxy S6 Q&A, Help & Troubleshooting] jaswinky:
http://xdaforums.com/showpost.php?p=62115360&postcount=11

Lli_pm_wlock seems to be related to modem (and kernel). It confirms what some of us were going thinking about it is not a samsung bug, but a Kernel (android, google) bug, because LG and other devices with MM have the same issue.

[Galaxy S6 Q&A, Help & Troubleshooting] Breach1337:
Could be coming from upstream or depending on what patches are merged in the kernel the S6 is using. Samsung does build its own kernels, so who knows what gets merged. I was hoping that I could identify the feature/app which would trigger this behaviour, but it could be also happening by the kernel alone regardless of whether there's shealth, location is on, etc. Since it's been in the April and May builds I wouldn't hold my breath, but let's hope the June update fixes it.

Disabling BlueTooth Share removes the two BT_* kernel wakelocks, but it doesn't really help much, at least for me. I am also pretty sure this would disable BT.

I'll do tests over the coming days with each setting enabled to try to see what causes what.

After disable google backup, I don't have more drain. Battery drain ~2% per night (BT, WIFI OFF)
[Galaxy S6 Q&A, Help & Troubleshooting] Breach1337:
Yes, I did. Disabling Google Backup fixes the issue with Android System's battery drain. What is your average Android OS usage percentage? I'd normally expect it to be under 10% and not keeping the phone awake 25% of the time as is currently the case. With everything on right now I lose about 10% during the night which is not OK, and that's with Doze.

I think the OP means he doesn't want to answer OR reject the call, just ignore it so it goes to voicemail after the normal delay.

It took me a while to figure out how to do that with heads up notifications. It appears that you can swipe up on them and it will push them to the notification drawer, instead of dealing with them.

I've never tried that with a call, because I either answer, or reject. Why make the poor person on the other end wait to leave you a voicemail? Just wastes everyone's time, IMO.
