Battery Drain and "Android OS" data hog?

Hello everyone.
Don't know if this is a known problem, but after upgrading to 4.1.2, battery doesn't last nearly as long as in ICS or GB. I need to plug the phone one or two times for a while through the day.
Besides, something is hogging the data in the background. I use Onavo Count to keep an eye on data usage, and recently an app identified as "Android OS + Others" appeared on the top list. It sucks around 5 MB a day, which isn't much, but my monthly data cap is pretty low and this never happened before 4.1.2.
Any ideas? Do you have the same issue? Thanks in advance!

Regarding battery drain I advice you to install Wakelock Detector to see which processes are using most of your CPU and battery overall.
After that, if your phone is rooted, install Greenify and freeze every app that you want to freeze when phone goes in standby.

Greenify works with system apps?

Donation version can greenify system apps.
Alternative, although a bit different, is to freeze apps via Titanium Backup.

Try doing a clean install again(wiping data)
Or disable usage and error reporting services...also disable background data(not sure if it's on jb as am on cm10)
Also if u don't use Picasa delete mediauploader.apk in System/App
Should decrease quite some battery and data use

What most people think android os is on a battery use log is wrong. For instance, write down your android os number, go watch a YouTube video through the app.. android os usage should have risen in the battery usage and data usage number. What android os is, is a catch all for apps who don't store stats for data or battery usage under their own name. YouTube comes up in data and battery usage but in tiny tiny amounts, compare it's number to even the shortest video you've watched and you'll see it doesn't match up but what's added to android os does. I use YouTube as a simple representation of multiple apps that do this. Battery usage in android devices can usually be backtracked to data usage, turn data off battery life doubles even triples sometimes.

Thanks, just did a clean install, rooted, and deleted mediauploader.apk. Will report back in a few days.

Nope. Got rid of MediaUploader.apk and the phone is still consuming a lot of data. No difference with battery life either.

I had the issue of battery drain, and phone heating up, and the phone lagging all time, for my XS. Flashed official JB, problems re-occurred after a few weeks. Now recently I again did a factory reset, and has been selectively installing apps/enabling services to locate the cause. Till now I have seen the google location reporting (not the general location settings) consumes a lot of battery. You can try disabling it (from google settings) and see the battery usage. Let me know if that was the cause for you also

[Q] Battery drain on Note 2 after 4.3 update

Hello
I have had a massive battery drain problem on my Note 2, a couple of days after the 4.3 update. While being idle during the night it loses 25% to 30% of its battery and while using it I can literally see the percentage drop. I have tried everything that I could find on the net. EVERYTHING! Nothing worked. These included: Factory reset (twice), letting the battery frain completely and then recharging it while the phone was switched off, switching off all sync,disabling bloatware including KNOX components (the actual KNOX app is not installed), installing only a few apps after factory reset, using Gsam, Wakelock detector, Deep sleep battery saver (which could not make my phone sleep), no GPS, no 3G, wifi on only when needed and more besides.
The phone is only one year old and unrooted. On 4.1.2 it had a beastly battery performance of almost 1.5 days of normal to heavy use, with 300 apps on it. Now it cannot go for more than a few hours with the same use.
I cannot say for sure but it seems to me that the drain is the same when it is sleeping and when I am using it. Wakelock has given me a 75% awake time even though I only use it for 15-20% of the day at most nowadays. Battery settings show everything normal, or at least I think so, eg Screen 35%, Android OS 15-28%, Voice calls 10%, Android system 5-15%, Cell standby 7%, Device idle 4%, Media server 4%. The batttery chart shows a constant steep drop all the time.
The problem started one day when the Media server went mad consuming 50% of the battery. After I did the factory reset it has never again been a problem but the drain still persists.
I have also read that it's a mess up between syncing of Samsung apps and Google services, but I have no way of verifying that.
Can anyone help?
Thanks

I had the very same problem until yesterday myself but think I found a solution on the web.. Uninstall Google Search and Google Play Services and the goto the Play Store and wait for them to reinstall and that's it....! As I found that there is a bug in Google Services (Nlpwakelock and Location service)
Hope this helps...?

Thanks. I already have Wakelock Detector on. I mistakenly wrote "defender" instead of detector on the original post. It gives me Viber and Messenger as the most active wakelock apps. But they both were not installed when the problem started. Besides, on the 4.1.2 they created no problems. In essence I believe that Wakelock Detector cannot help much. Whatever this problem is , it is well hidden. Thanks for your interest and help anyway. Much appreciated.

Which kernel you are using? And also i recommend using Greenify. Widgets usually eat a lot of battery, I went from battery lasting only 8 hours to get my battery use only 30% in 8 hours.
What i did: installed wakelock detector, gsam battery monitor and better battery stats.
Monitorized the wakelocks.
Applied greenify to the apps which were waking most
Removed widgets which were waking alot
Installed Toggle 2G.
Kernel settings: 200-1600mhz | zzmoove | AFTR+LPA | Multicore power saving (SCHED_MC) = 0 | GPU = stock settings
Works like a charm for me. Hope it helps! Any question, ask!

I've read all sorts of things about this problem since I updated and got hit. I have too much app data to lose by trying the factory restore (which by all accounts shouldn't change anything anyway since you'd still be stuck with 4.3)
I finally decided to try the age old blackberry cure-all: "if in doubt, pull it out" (the battery). Since the entire issue seemed to be related to battery caused problems (ie slow charging, fast drain, etc) it made a lot of sense.
And it worked.
I think the main reason this isn't more commonly tried to fix issues on Android is the same reason I didn't try it earlier. My case is pretty serious and isn't easy to remove. I'm glad I did take the time to take the case off though or I could have ended up wiping my phone.

Thank you for the suggestion. I have already taken the battery on and off several times. It had no improvement. The phone is only a year old, that is why I don't believe the battery is the culprit. Besides, problems started only after the 4.3 update. Before that it was working perfect. Too much of a coincidence.

Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.
As I said, I've read all sorts of suggestions, many of which don't work for everyone (such as the factory reset) - this is hopefully just one more thing for people to try before they end up wiping their phone in desperation. I mainly posted here in the hopes that others with this issue that may not be forum members can get some more suggestions.
At least for me, wakelock and all the other diagnostic tools at my disposal showed nothing different to before the update. Many other people have found that the Android System is using a lot more of their battery than normal or some other apps are involved - if this is the case, it's likely to be a combination of things causing the issue (the firmware, the drivers, apps, hidden Samsung processes, etc).
Also, for what it's worth, I found that Knox supposedly wasn't installed (when I find it in the apps list, the button to install it is showing...). But it's showing in the list of apps so it must already be installed. I dug through the list of running processes (had to show the system processes too) and I discovered that several Knox and some other new Samsung processes were indeed running.
One other quick tip - If you wanted to check/tweak the 'developer options' and can't seem to find it any more, that's because it's now hidden since 4.2 - go to 'About Device' and tap 7 times on the Build Number. I tried disabling all background processes however it seems this only disables application level processes, not system level processes but if you've tried everything else, it can't hurt to try playing around with some of the options in there.

Thanks mate
I think you are right. It is probably a combination of many things. I have opened the Developer options some time back. The one thing that I do for sure in there is limit background processes to 4. Besides that I don't experiment much, exept maybe to change transition animation scale. I am actually thinking of rooting the phone and downgrading to 4.1.2. It was just fine before. I can live without the 4.3 add ons.

The only battery apps on my phone are the 3 mentioned above, so I don't know what the battery monitor that keeps my phone awake is. The drain existed before I installed these apps. I have read that Chrome could prevent the phone from going to sleep but it is disabled on my phone.

I faced same battery drainage issue, after installing wanam kernel and freezing all bloatwares through Titanium Backup. I'm satisfied with my battery now.
You can try.

Here is detail-
Disable sync always, enable when needed.
Disable wifi always scan from settings
Display set to auto
Uninstall apps of playstore you rarely use
Use widgets on lock and homescreen as less as you can (I don't use any)
Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-
profile: normal
Governor: pegasusq
Scheduler: cfq
Don't touch other tweaks, hardly you can tweak sound boost.
THIS GIVES ME A SATISFIED BATTERY STATUS.

Android OS wakelock

Hello everybody.
I have recently rooted my phone to try and identify the cause to my fast battery drain, which is primarily from the Android OS process.
I can't seem to find it. I see that the process "system" is working a lot and that the Android OS is awake for way to long.
Maybe you guys can point out something I'm missing here.
I would appreciate every help from you !
Thx

This really could be anything. I recently had this and experimented for days whenever I took a break. For me, it turns out that it was my work's wifi hotspot making my phone stay awake to stay connected. I turned off wifi and it was fixed. But this isn't a solution. I ended up connecting to my own wireless repeater and problem was gone.
Bottom line is you'll have to figure out what's going on yourself.

I'll tell you what I've done for battery life on my phone and maybe on of those will fix your problem.
1. Uninstall stock bloat (only the stuff actually running in the background; no need to remove stock launcher ect.)
2. Disable Wi-Fi scanning when wifi off
3. Use Amplify to limit wakelocks and alarms
4. Freeze the apps you don't regularly use. I have a titanium backup widget on my homescreen that will unfreeze snapchat and launch it. It is the pressed again to freeze it after use.
5. Greenify apps you don't want running in the background for no good reason. If you get the donate version, you can still get GCM notifications so it's win win. For apps that don't have GCM notifications, it will coalesce the notifications so your phone doesn't wake up as often.
6. Make sure you have all logging turned off from the LG hidden menu.
7. If you're on a bad wi-fi network run by work/school, then get the auto disable IPv6 app on the play store.
8. Use the HEBF Optimzer app to prevent Google wakelocks and battery drains.
9. Use PNF Root app on the play store to custom choose how often your phone checks for GCM notifications.
With these changes, I finish the day with around 4 hours of screen on time doing regular things. Don't believe the posts about 7-8 hours SOT because you don't know what they were doing. I once used my phone as a timer while studying and had the screen on for 3 hours and only drained 12% battery.

absolutely the same issue here. No luck with factory reset, not using whatsapp or messenger, not using wifi, not using mobile data, no luck with any kind of debloating, uninstalling, installing greenify, amplify whatever. In the end, the Android OS will come back and drain the battery. I've spent a way too much time on this issue.

Try clearing the Google Play Services data, then removing all Google accounts and then adding them back. This time, make sure not to agree to any data collection.
When you turn GPS on, it should show as GPS only in the location settings. Disagree to any prompts.
If your location defaults to high energy GPS and networks, then try flicking the toggle on and off very quickly after you have cleared the play services data. This is how I got the prompt for data collection to come back. It's annoying and you have to always disagree but it fixed my mysterious battery drains from android os.

How to prevent apps from getting killed

Hi all,
I'm running several apps that should run all the time (AdGuard, Network Speed Meter) or for a long time (speed trap warner,...) but OxygenOS kills them after a certain period. Some of them restart automatically, some don't. Of course all of these apps are 'not battery optimized'. Is there any chance to prevent OxygenOS from killing them?
Are there custom ROMs that can overcome this problen?
I'm on the latest OxygenOS Pie Beta, but the behavior was similar on Android O...
Thanks a lot,
W

Did you try locking the app via recents menu?

Thank for the info, didn't know that.
Unfortunately it doesn't help, Adguard and the network monitor don't appear in recents. The speed trap warner automatically starts and stops when I'm in the car, i don't want to open recents manually every time.

This is not changing anything,e ven with disable battery disabled, even with adaptative battery disabled.

I have the same problem. I have not found any solution whatsoever. This is really frustrating. I've made sure apps aren't optimized. Advanced optimization is disabled. Developer options background limit is at standard. I've pinned the apps in recent apps and it still happens. Apps get killed all the time.
For example,
1. I use Google Fit to start tracking a run. Within 10 minutes of tracking, the app is closed and workout not tracked. Its not even like i touched the phone and opened other apps during this.
2. I have VoIP account setup in the default dialer. Calls come through only 50% of the time cause the dialer is closed.
3. YouTube Music, constantly gets closed if i simply pause the music. Within 2 minutes, the app is closed.
4. Trying to transfer 15GB of files through Explorer app from phone to file server, never succeeds if i don't watch the app and keep the screen on.
5. Plex gets closed and therefore my photos don't auto backup with the phone is plugged in.
This is absolutely ridiculous! Why the hell a phone with 8GB of RAM is killing apps is beyond me!
Custom ROM on the same phone, like Lineage OS, no issues. Can have optimization on, battery manager on and all. In fact, battery life is better on custom when its not killing the apps! Seems to be the only solution until OOS can stop killing apps so aggressively.

Question Why is my phone running hot?

Anyone know how I might go about diagnosing why my phone has been running much warmer than usual? Just browsing Facebook (posts, not video) for about 5 minutes with brightness around 25% the temp was up to 41 degrees. It happened earlier today when I was just using Chrome, and it happens most days now. The issue began when I updated to 11.2.8.8 (the very next day), and the phone overheated several times the first few days, evidenced by the system warning about temperature, then recovering several minutes later. I haven't seen the system warning since then, but it's frequently above 40 degrees just doing everyday tasks. Oddly, I haven't noticed it overheating when playing games.
I usually run Omega kernel, which has always run cooler than stock during both normal use and heavy gaming, but this issue has occurred with both stock and Omega, so it's not kernel-related. The only magisk modules I have installed are debloater (for YouTube only), font manager, and systemless hosts, so that's not it either.
Maybe some app going haywire (how to find it? Nothing in battery usage) or some system behavior that changed in 11.2.8.8? Anyone else have this issue or find what's causing it?

That's just how this phone is. It was worse when the phone released before all of the updates. They've been slowly trying to fix it with each update. The 888 is a hot *****.

I remember having that complaint when I first got it, especially when gaming, but it's been fine for me since like April, until this last update. And with Omega several degrees cooler. So there has to be something new causing it....

What version of Omega are you on? What build of OOS? AA, BA, DA? Are there any unusual rogue apps that you've noticed running more than usual?

Latest version of Omega (8/7) since yesterday, but was having the same issue on the previous build (7/30). I'm on OOS 11.2.8.8 BA.
I haven't noticed any apps using more battery than expected, but I guess that might be part of my question... If there are any, what's the best way to find them? I'm not seeing any useful info in BBS or anything in GSam I wouldn't expect, except overall battery drain is a bit higher when it's been running hot. I do have a lot of apps installed and should probably clean up what I don't use, so I guess that's a place to start.

Find which apks are using the battery.
Google system apks are prime suspects.
Trash apps like FB, WhatsApp, LinkedIn... none of that junkware runs on my device, ever.
Examine all startup apks closely, take out the trash.
Power management can end up causing excessive battery usage, try turning it off.
Track down each battery hog and deal with it on a case by case basis rather than the flip a switch shotgun approach.
I use Karma Firewall's logging feature to help track down offenders.
Dependencies... sometimes the source of the high usage is hidden. What apks and services are running? What apks are using what services and why? What's apks are getting cached first when you clear them all? Any memory leaks?
Play with it... Androids wuv attention

Good ideas. I just installed Karma Firewall and will see if it turns up anything.
How do you manage startup apps and running services? I used to use Servicely, but with Android 11 I find that even when I disable apps at startup they still start on their own, and it seems to use more battery than it saves. I've since disabled all apps of that kind and just let Android manage things itself. The only thing I do is go to individual apps and turn on battery optimization and disable background data if not needed, and I keep apps I don't use often in Icebox, including Facebook, which is the only social media type app I have. (Uninstalling FB isn't an option unfortunately.)
What do you mean by "which apps are getting cached first when you clear them all?" and how might I find it there are memory leaks?

The only thing I do is go to individual apps and turn on battery optimization and disable background data if not needed, and I keep apps I don't use often in Icebox, including Facebook, which is the only social media type app I have. (Uninstalling FB isn't an option unfortunately.)
What do you mean by "which apps are getting cached first when you clear them all?" and how might I find it there are memory leaks?

Karma's logging feature doesn't work in 10 and above I believe, I run Pie. See what you got though. It will still block apk internet access though and uses almost no battery.
The battery optimization option can cause erratic behavior and I never use it. Close apps when done with them. Brave browser for instance will run in the background until closed.
Developer options>running services memory leaks show up as an apk who's memory usage just keeps increasing with time. It can get quit large. These are rare and poorly coded programs. More common on Windows.
Keep an eye though for memory hungry apps as they may be using excessive power but not always. Small memory users can be worse. Dependencies, sometimes a apk or service keeps making repeated requests because of a disabled apk or service.
Killing Goggle play Services and Playstore when not needed will help battery life.
Google backup Transport, Framework and Firebase are always disabled on my device.
All carrier, manufacturer, and Google feedback are disabled.
I have a Samsung device and I use its Device Care app to clear the cached apks. Then watch as they repopulate. You'll need an app that does this. In running services you can disable a suspect apk and see how long it takes to come back. I find that Device Care is more effective though and that ability has let me track down some misbehaving system apks saving me a reload.
FB is weaponized and a proven liability. Known data miner. Purveyor of disinformation and dissent. It has ruined countless lives and careers. It deliberately makes you have load the app to be able to send messages. If this last year hasn't taught you what you need to know...
I used it for one month 15 years ago and knew what it was back then. It's far worse today.
Don't feed the beast.

Thanks for the info, it's interesting. However, if you're running Pie & not even using a OnePlus device, none of this is going to be applicable to my issue which is specific to OOS 11.2.8.8 on this particular device, only present since last month's update.
Re: FB - I'm required to use it for my job (well, second job), and I need it on my mobile device in order to do that job, so it's not going away. Freezing it when not in use is the best I can do.

You cross platform OS version and manufacturer to find solutions. I have a lot of posts here but few asking for help because I do the above or just keeps at it until I work it out as it's my issue.
*shakes head*
You've painted yourself into a corner.

@terlynn4 I use BatteryGuru because it uses root to find rogue apps that are draining battery unnecessarily. Give it a go and see if that helps pinpoint the problem at all.
