[Q/ GSM version] Battery Drain due to Media Server

Hi all!
Recently, I updated my Galaxy Nexus to 4.1.1.
I found that the battery drains. Battery level went down 1% per minute.
I did not meet this problem when I was using 4.0.4
How should I fix this problem?
Thanks a lot

Hmm.. same here. Battery Life was better on ICS, that I agree. But JB is really awesome! Anyway, about your problem, I suggest making sure you kill your apps more frequently (Going into MultiTasking and just sliding them all away). This seemed to help me.

I have been trying to figure this out for days. I've read countless threads with no luck. I've got no mhaic , videos or pictures on my phone and its still using a lot of battery. Willing to offer bounty for a proper fix

Just the worst advice ever. You don't need to manage your tasks. If you've got an app misbehaving that's causing drain, you need to uninstall it and use something that's coded properly.

Well that's true. Sorry if I said it wrong. But yes, some apps are coded horribly like Facebook and cause terrible battery drain. So, just uninstall it.

Search the forums and download better battery stats - you can also purchase the paid version from the play store - Run that for a day or so and it will tell you what is eating your battery.
Also, some more information (screen captions, your 'average' use, ROM, Kernel, etc) could help this thread a bit as well.
If you have a rogue app that is causing drain, better battery stats will help you find it.

After I got a program which tests mp3 files and removed all which had errors the media scanning stopped going on forever and killing the battery. I don't know which program off hand but I bet there are several free pc apps to test mp3's online.

This does not kill apps. It merely removes them from the Recent Apps list. If you want to kill apps, you have to go to the Apps manager in settings and force stop. Or use apps that offer such functionality like Android System Info.
---
I also have this issue, but force stopping the medisscanner (or related apps) resolves it temporarily. I'll try the mp3 validation suggestion

Solving of Battery drain Issue
Please check on your device on app which using most of the battery. I used GSam Battery Monitor so that it will shown me the most usage of apps consuming the battery. Just tap on it, tap "manage" then tap on "Force stop".
This accually required on every charge, restart or playing / downloading a media files. Some people suggest clear data on media storage, however, it clear all your custom ringtone and others too. By doing Force stop, nothing will be affected....
Enjoy!!

Help Required Battery Drain

Hi Guys,
I have been experiencing battery issues where as the battery is dropping from 100% to 90% overnight with (Idle Phone no missed calls or messages) tonight will try in Airplane mode just making observations.
WIFI =OFF
DATA=OFF
GPS=OFF
SYNC=OFF
where as earlier it use to just drop by 2% ,I've always user Redpill Kernel and gave wonderful battery life,
Rom is monxDified
I've installed Battery Stats Pro it shows the Battery eaters are Facebook and XDA but i uninstalled these also still the issue persists ,
My note 2 is just about 3months old i don't think its a battery issue or a replacement would be required,
So anybody faced some same issues or any tweaks and mods that you guys have done on your devices please share I would really appreciate .
I've Read couple of posts on Greenify and Snapdragon guru none are helping me

Install BetterBatteryStats (or Wakelock Detector) to check what could be the reason.
Did you recently install an "unknown" new app?
EDIT
You can also try Autorun Manager to freeze modules' apps at boot.

I made a nandroid backup flashed the rom n no apps installed stock kernel only xda installed so far average keep monitoring n keep posted .

Hi,
How about a full wipe and then test with your ROMs stock kernel first.

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.

Wew 4.3 does have may bugs

Can someone please tell me what's causing my battery drain?

I even broke my phone with App Ops trying to figure it out, disabling wake permissions for most apps which caused FC's and even reboots. I have since restored all permissions but I still get FC's whenever I leave an app or switch out of it. Not sure if it's really crashing, but I get a FC message every time. So much so that Substratum turned off its theming for Files because it "crashed" after every screenshot was successfully uploaded to this post. Btw I just removed CrossBreed Lite and it seems to have helped. So far no reboots doing the same stuff that caused reboots! Not sure why it caused problems though. I used it for a few days with no issues.
Anyway, back to my battery woes. 30-40% kernel system usage. Why is this happening? Even Snapchat which is abusing wake locks is nothing compared to kernel system.
I'm running the latest build of AIM 8.1 with EX Kernel. I have just visited the other thread about tweaking governer values to optimize battery life so I'll report back with results although I doubt that's relevant to my battery drain.
I've Googled quite a bit on the subject and it seems that each case is different. Usually caused by a certain bug, although a lot of people say it's "normal" which I strongly disagree with.

Update: optimizing the CPU has definitely made an improvement, but the kernel battery drain still exists.
Could it really be pick up to wake and wifi search behind the drain? Isn't this phone supposed to have a sensor hub that allegedly allows for all sensors to constantly be on while using minimal power? I never noticed this drain on any other phone with both of these features on.
Anyway, I disabled pick up to wake and I'll start trying to remember to turn off wifi when not in use.

I think you're trying too hard and running a bunch of stuff. The kernal usage looks about right. I wouldn't run Gsam and BBS at the same time. They can fight each other. What makes you think there's a problem? Nothing jumps out at me.

I also can't see anything out of the ordinary, except this one picture where it shows the phone being active while dozing. I don't know how to understand that because I don't use that app, maybe I'm reading it wrong. What does Android's built-in battery monitor show? Is it dozing properly while screen is off? What is your average SOT? Is your mobile signal strong? I'm also using AIM 8.1+EX combination with satisfying results. Is your radio up to date?

maybe Wakelock Detektor or Greenify can help you.

And if you currently have things crashing all the time, start with a factory reset. Much easier to diagnose the cause when the apps aren't doing random stuff.
