"Android OS" keeping phone awake... and using data?!

Hey,
I have a Fido RHD on the latest official ROM (no root or unlock). I have noticed over the past few weeks that the battery life has been a lot worse, but I can't think of any particular app that may be causing it. Strangely, Android OS is using a lot of CPU time and also sending data!
Things I have tried to do:
Stopped all the optiona "location services" for Google apps (e.g. Google Now)
Installed Snapdragon Battery Guru (but it is currently in learning mode)
Uninstalled all unneccessary apps
How can I find out what is hammering the "Android OS" process, and why it is keeping the phone awake? Is there a more advanced battery stats app that could help with this?

Hello Suman,
I have a similiar issue here. Android OS is not heading my battery stats, but it held the phone awake for a reasonably long time. You should try downloading BetterBatteryStats (the apk is available here in xda dev for free, but the developer did a nice work on it and the app is very useful, so I think you should support the developer if you don't mind). For a better understand of what's going on open BBS and set a custom ref before you go to sleep. Save the dump immediatly after you wake up. Post it here. Anyone that understand partial wakelocks will be able to give you a better support.
I have seen another guy here with a similar issue, but still unresolved. Also, I still have the problem, but my ROM is different (Vivo - Jelly Bean).
If you have received the update recently via OTA, you can try wiping data. Not sure if will help, but wiping data after receiving major updates is always a good and recommended practice.
Also, if you have instant upload on, turn it off. A bug seems to cause the instant upload to try syncing every minute so you'll have high times of SyncLoopWakelock keeping the phone awake most of the time. It happened to me. If a cloud backup of your photos is very necessary as it's to me I recommend Camera Uploads feature on the Dropbox app.
Let me know if something helps!

Ok, I will give BBS a go, thanks for the recommendation.
I did a factory reset as soon as I received the JB OTA (I always do this after any major software update). The Android OS problem did not start right after the update - it is a fairly recent problem.
I don't have Google+ camera upload turned on (but I do have Dropbox camera upload, as you suggested).
Thanks,
Su

Hey,
Bit of a noob question I think... how exactly do I "use" BetterBatteryStats. I'm not sure how to set it up so it measures what I want it to.
This is what a full day's drain from 100% to nearly empty looks like at the moment:
Can anyone shed some light on my mystery battery thief please??!

Tell me the threads please.

Wow what a fix! I have a better one -
1. put phone in garbage
2. buy a nokia 3100
OR:
put phone on flight mode and use it ONLY to tell time.
And on a more serious note:
C'mon dude, are you serious?.. a "fix" means you don't loose any functionality of the device, what you did there was disabling almost every good and important feature that in the first place is the reason people buy these phones, so disabling them to get around a bug which drains the battery?.. that's.. well I don't need to say it.
And for the fix that does work - turn off "Location reporting" only - from my experience this will not make you loose any location based functionality as I use every thing that has to do with locations, Google can still tell where I am, and Google now still tells me time to work\home, flight times, packages dispatched, weather updates etc. turning "location reporting" off fixed the Google services battery drain issue I had, and I still turn it on from time to time to see if Google had fixed this, last time I checked it was still draining the battery.

I think the guide is not for u, mate.
But this guide is for people who wants to prolong the battery life.
Location reporting is one of the main battery factor on an android device.
I personally don't use it as I don't want any apps (facebook, etc) to do this and I have disable more google-related things than what the OP has posted.

Are you for real or is this just some kind of joke?
Firstly, this fix isn't a fix, its just turning some things off.
Secondly, this information has been around for a long time now and is relevant to any Android phone, not just the S4.
And no, I am not going to post links to the hundreds of threads and posts on the many websites and forums out there who have already posted this before you and with more detailed information.
Seriously, why have you bothered posting this rubbish?

The most suitble statement is the tip for prolong the battery life. Tks OP for yr sharing.

Install BetterBatteryStatts to monitor app by app activity and CPU Spy for deep sleep issues.

thank you for your first advice.
but i don't see an app which could cause my issue.

First i would disable Network Location for positioning and set it to gps only. Second in wifi settings disable scanning always and check avoid bad connections and check optimize wifi. Guess this will help a bit.

Facebook App..well known battery killer.

Also download Gsam, that will tell you what apps are draining your battery

According to gsam it's the kernel?
I've used the facebook app so i assume it's usage is OK

Download this -
https://play.google.com/store/apps/details?id=cn.wq.disableservice
And make Facebook and Google play services look like this -
It massively reduces the wakelocks and effects nothing I've found so far

Thanks a lot but i don't get why it's facebook's fault when gsam says it's the kernel.
In addition: i force-closed facebook and the facebook calendar sync and my CPU is still on fire

Weird. I wonder if it's something syncing or the background Wi-Fi scanning or location reporting?

Android os is built up from services, like sync and location, from all apps.
So yes....things like Facebook especially, will make android os rise.
Go a day with location and sync off....and disable Facebook and similar social apps syncs....just to test. You'll see.
The more you run...the higher android os will be. Its just life. Have to decide what's most important. Those apps and services, or battery life.

I'd definitely say try what I said before with the disable service app. Cus it looks very gms core and location wakelocks

Maybe you're right, i don't know.
But there is one thing i don't understand:
My CPU freq was still on max this morning (Nexus has been on charger overnight of course).
After rebooting it everything was normal again.
Then i manually startet facebook and the facebook calendar sync.
After it has finished the cpu freq was at 300Mhz again.
So i don't get why those app should force the CPU to stay at that high freq.
Ever after closing G+, FB etc. after using it the CPU freq stays low.
Every few days i have this strange behaviour and i don't have a clue why.
I'll give the disable service app a try but i'm not optimistic.
Isn't there an app which shows me which app, service, etc is currently using my cpu?
quick system info shows 0-1% to every app

Do you usually do soft reboots by any chance?
Sent from my Nexus 5

No. The only time i reboot my device is when flashing a new nightly. About 1-2 times a week

I deactivated the services and everything went well about 1 day.
But now it's happening again
Please help

Something is messing my battery up.

While using Twitter or any app, my battery goes down at least 4-5%. I can't get decent battery on this.
I have the Verizon edition.

After charging the phone i think in all editions you need to reboot in order to stop the battery drain try it and tell us. It is like a "bug " on current firmware

The bug i told you is from android system battery drain
twitter and also facebook are battery non friendly....
i personally deactivate facebook and twitter with package disabler pro when i dont use them.
post your android systems battery stats
you had 25 mine is between 15-18
is your phone band new ? if yes maybe you need to let the battery make some charging circles

It is pretty new. I didn't think that would effect anything. I guess I will let it have some cycles then.

I have some ideas that might be able to get the problem solved. I would first try turning off your phone for 5-10 minutes since it might be overheating. Then I would uninstall any new apps that you might have installed since you can remember the battery drain starting. There is a small chance you might be experiencing some battery drain issues from a third party app that caused a virus. Its also a good idea to get a security app like avg since its free. Other then that you might also want to check that your phone is not completely full on storage, and also consider turning off the facebook app since it can cause some serious battery drain issues as well. I think thats pretty much it if you want to get rid of facebook on your galaxy s7 here is how to do it. and it will really help with your battery life

I had the same kind of battery drain on my Sprint variant. A factory reset quickly fixed that issue for me.

So I used it up for a day and let it die completely. Charged it right back up and now its pretty bad today. These are screenshots from when I made it die.
I did disable Facebook. The Android System and Screen are using the most up right now. It went down about 7% for being almost idle. I used Twitter once.

Possible Solution to the DRAIN!
Ok, so I've had the same issues as you. My findings are as per Gsam Battery Monitor:
1. High Android OS and Android System usage~ 20-30%
2. High Phone Radio ~ 40% at times
3. Overnight drain of at least 4% (stanbby drain)
4. Screen usage 'while off' higher than 'while on'
This was frustrating and is as mentioned by other users to be a bug from updates and related to charging.
SOLUTION:
Today Gsam reports my Android OS and Android System usage and Phone Radio at 10% and below.
All i did was...
1. Let it drain to about 90% after charge.
2. Restart the phone.
3. Then plug in the micro USB to USB connector (the one that comes with the phone) with a flash drive attached and play a song/short video.
4. Unplug and enjoy great battery life.
This worked for me so it's worth a try. Will test a full charge soon and hopefully it doesn't require the steps above every time to stop the drain.
btw I'm NOT rooted, using LTE.........wifi,bluetooth, AOD and locations all off.

Question How can I stop battery drain on "screen off"?

I'm happy with the battery performance, but only when the screen is on. When I use the phone mostly with the screen on, I get good SOT(6-9 hours), but with the screen off, the battery consumption is terrible. How can I pull this down?

Probably a cloud app; try temporarily disabling Google play Services, Google backup is a dependency as is Playstore, Gmail. Some apps also need it to run. I enable it once or twice a day. Disabled saves 1+%@hr.
Trashware social media apps like fb, WhatsApp etc shouldn't be installed. It all adds up.
6 hours SOT with a 5002 mAh battery isn't good, 9 hrs is fair to poor. That said all Samsung's should be optimized for best performance.

Thanks for your opininon. Are you saying we shouldn't use Whatsapp? Is it real solution?

Unfortunately, because of SD 8 gen 1 limitations (probably worse on Exynos variant), about 6-7 hours SOT is best you're going to get on the S22 ultra.
Try the following guide here & see if it helps your battery life.

I have the Exynos version. My phone has a SOT of about 10 to 12 hours. Rooted and bebloated. I do have the brightness very low though.
Android 13.
OneUI 5.
Latest.
Lightly debloated.

That's interesting. I guess depends on what apps the phone is using during SOT.......
Mind sharing your battery usage breakdown screenshot?

Real as it gets. All social media apps should never be installed. Many should even be logged on to. WhatsApp track record is stunningly bad.
Lots of users means its got a huge bullseye on it even if they try to secure it, it will hacked again like the sun rises in the morning... for sure. Meanwhile phishing scams run under the radar and count on you screwing up. And many do.
You got to ask yourself one question,

No really. The problem is that all the apps developed by Meta (Facebook, Instagram, Whatsapp) are power hogs. Meta does not care if it chews up battery. The primary reason is that Meta is shoving ads in your face. Even when your screen is off, those apps are running in the background. Meta is not the only offender. There are plenty of other app developers that do the same thing.
Also, there are different "flavors" of Android. Each OEM implements it differently (even within the OEMs). This makes it less cost effective to customize their apps for each OEM. There is only one flavor of iOS and iPadOS, so it is much easier to tweak it for iPhones and iPads than it is for Android devices.

I understand. Thanks. I have another question. You said you turned off google play services. When I turn it off, notifications do not work and many applications do not work. How do you overcome this situation?

It doesn't effect any notifications for me that I use except Gmail. Most my apps run without it. I tend to shun those that do.
Some of the Samsung apps take the place of Google apps, no need to run both.
If killing Google play Services helps at night it's likely Google backup Transport running.

Hello, I have something to ask about. I need to know if there is any ability to store a system application variables usin adb. Imagine that I want to open my settings app and do something mabye a confirmation dialog will be shown in order to say something such as alert for something supposed that I did click on OK, i the normal case this alert will never be shown even if you clear the settings app data or clear the cash, is there any way to use adb to store the settings app data before opening it the if anything as the previous senario happened I can restore the settings app to the moment before clicking on the OK button or even before this alert has shown

Many apps that "need" Google play Services are Playstore pay apps. This can be circumvented by first allowing the app to activate, then firewall blocking their internet connection. Firewall block Playstore as well although it should be disabled except when needed.
If an app doesn't need internet access to function it should be firewall blocked anyway.
