HTC One M8 :: Kernel Or Android System And Media Server Battery Drain
Nov 17, 2014
the GSAM app on my HTC ONE M8 says that my app usage is higher than my screen and three of the main battery drainers are: Kernel (Android OS), Android System and System (Mediaserver).
I use my phone properly, charge it very well and have had 4 android phones. None were like this. I have the latest firmware for the M8 (4.4.4). My screen on time is not that good now, around 2-3 hours but when I first got the phone (3 months ago) it was 4-5 hours.

I just got my new One M8 a few days ago and ran into some battery draining issue. After charging the device (second charge if to be precise), I went to sleep with 99% battery while all apps are closed, Wi-Fi is turned off and Battery Saver wasn't on. After 6.5~ hours, the battery was at 89%. In my opinion 10% drain overnight, during standby is a lot and that's why I'm a bit concerned.
Based on some recommendations, I installed GSam Battery Monitor, please see below results. It looks like Kernel and Android System consumes 36% which is a lot. How to decrease the consumption and what causes the Kernel and Android System to consume 36%?
On that matter, it seems like the GSam consumes 5.8%. When I close the app, does it stop monitoring and consuming power or it works in the background and keeps sucking the battery?

Having issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.

I have this issue and have spent the last 2 days trying to fix it to no avail. I'm wanting to start a fresh to resolve it which means wiping internal storage of music/photos etc. One question though, what's the best way of doing this to them install a fresh ROM?

LG G4 recently, specifically the battery life. Yesterday, it somehow discharged from 100% to 20% three times in one day, on normal usage. I just don't know what is wrong with the phone. Android (and GSam) claim that the highest user of battery is Android System and Android OS.
What I have done:
-Used LG Access Lock to deny keep awake and location permissions
----worked for a few days and then battery life fell back off
-Full reset of phone
----battery life is actually worse after the reset
-Battery saving location settings
Possible suspects:
-Pebble watch --- constant on bluetooth maybe?
-Facebook/Messenger/Snapchat/etc --- wanting my location constantly?

Ever since I installed the 5.1 update ,media and mediaserver are draining my battery at a ridiculous rate ! They get up to 70% battery drain ,i've done the reset and removed and formatted thesd card only to have them return and start again.

So when I opened up my battery usage I noticed that Android OS was at 70% usage (69% now in screenshots). I check my battery usage several times throughout the day and Android OS was not consuming 70%. It seemed to spike to 70% consumption, which points to an error in battery usage charts.
The steeper drops at the beginning and toward the end can be attributed to the poor reception areas I was in and my heavier screen on time during those periods. The flat portion in the middle is when I went to bed and left my phone for about 8 hours. Notice there are no huge wake locks during my time off battery.
This is my current screen on time....
I'm guessing this is an error with the battery usage calculator but I'm not completely sure. How to know if this is an error with the battery usage or is Android OS really consuming 70% and how I should fix it?

Having bad battery drain on the Galaxy S6, always seems to do it when on 3G and when travelling. It seems fine on WiFi. Here are some screen shots,

Strange that there aren't much complaints about that, but after I got the even buggier 5.0.1 update, the WiFi's battery drain is unstoppable. My usage and settings are exactly how I left them before the update several days ago. WiFi uses about 60% while the phone sleeping. No abnormal wakelocks details detected

My phone is one of the "not so good battery" variety, so it needs to be charged mid day every day.
Today I couldn't go to work due to hurricane and thunderstorms near me. so I sat back and played some N64 Zelda for 2 hours and what do you know, I'm at 60% with 2 hours of SoT... probably the best SoT I've ever gotten (I'm guessing I'm gonna have 5 hours SoT today? estimate?) but when playing something like dead trigger with the same exact Bluetooth controller the battery drains much faster. (I would say the same battery wasted in half the time)

For the last couple days, I haven't been able to get more than around 4 hours from a full charge. The battery usage tool lists "Media" as the major culprit. I'm also getting frequent notifications of high CPU utilization from the task manager tool, though nothing interesting shows up in the task manager application list. (Maybe the "Media" service doesn't get shown there?) I recently upgraded to 2.3.6, but things seemed fine for the first few days, so I don't know if this is related.
I think I might have caused the issue when I removed a few mp3 music folders from my SD card using the Astro File manager. (For some reason the stock file manager would hang on trying to remove them, even though they weren't in use.) That seems to be roughly when the battery drain issues started. Also, I currently can't open the "Music" or "Gallery" applications - they just hang and eventually I get the force close option. I've rebooted multiple times, but this doesn't go away.

I've got a very big problem, since the last update im experiencing heavy battery drain and as i can see its becouse of the "android system" uses 50-90% of battery.Before the update this number was around 3-10%. I dont know what to do,my phone gets really hot and the battery percentage drops in minutes.

So the Android System is using a lot of battery. I was using Twitter and Facebook mostly and played around with the stock camera app briefly.

I usually watch Netflix in bed then go to sleep. In the last week, I occasionally wake up to find my batter drained (down 80+%) overnight. According to GSAM, the culprit is Android Core Apps. Not sure what that is. I thought maybe Netflix was still downloading, but that's not Android Core Apps.
This is Nexus 6 on 5.1.1 using mobile radio only (no wifi).

And my s5 is running HOT. I can't put my finger on it. I went from 100% battery to 11% in less than 6 hours on standby. What processes may be draining he battery? Location is off, battery doctor and CM security take care of all junk and background apps, sync is disabled. I'm shocked!

I have recently noticed that whilst playing Spotify (and also after) media server seems to be using up lots of my batter. All my Spotify songs are saved onto my SD card, and I understand mediaserver plays a part in playing the songs but I was wondering if it is normal to have such a high percentage? I used to have amazing battery life on my M8 but ever since buying this SD card it seems to have taken a tumble.

Media server is killing my battery, and fast. I mean a 40% drop in 2 hours yesterday while phone was on sleep with wifi and mobile data disabled. I'm in the UK using S5 900F standard model on kitkat 4.4.2.
Since then I have:
- unmounted Samsung SD card (it only had a few photos and apps on it, had it a week)
- force stopped all "media apps" despite dire warnings as to world ending if I do so etc, and cleared data
- repeatedly cleared cache
- rebooted phone in safe mode and am monitoring. Battery drain is better but media server is still the main culprit at 27% (down from 51% but still..)
I can't keep it on safe mode all day as it's highly inconvenient.
Phone is unrooted, 3 months old so warranty is important. I can't download mediaserver killer etc
I am unable to isolate which media files are causing this or why. I thought it was the SD card which I added recently but it's a Samsung and should work, plus the problem hasn't disappeared after removing it.
I haven't downloaded any apps since the problem started, or downloaded any media files. I have no games on the phone. A little music, Spotify premium (force stop and now disabled by safe mode), 50 photos. Before the mediaserver problem started about a week ago, battery lasted 1 1/2 days at least. I'm not a heavy user of online media (bit of YouTube but never download or watch movies on my phone).

I've had the RAZR for a few days now, and one of the main things I used my last phone for (droid x) was to listen to music at work.I've been listening to music these past three days, and when I look at the battery use chart, there is something called "Mediaserver" using up a significant amount of battery life (~20% or more if I've listened to a lot of music). On my droid x I never saw this process on my battery use, and I am wondering if there is an option or something that I am overlooking that is increasing the amount of battery drain from listening to music.I listen to mp3s on the stock music app and to mp3 and m4a podcasts using Pocket Casts.I can't say for sure, but Mediaserver seems to not appear on the battery list until I start listening to music and to not increase the amount of battery that it uses while not listening to music.

I generally don't have trouble getting through a work day with my S6, but I do wonder whether the Android utilization is high. During a typical day (1 - 2 hours SOT, 14-15 hours off charger), I'm burning about 60%-70% of total battery, 30% of which is Android System (~22%) and Android Kernel (~8%). Google Play and other apps are all typically < 5%. Is this normal, or does this indicate that a factory reset might be a good idea? On previous phones I don't recall core Android being this high (usually <10%).

I was working after lunch and noticed that my phone was getting hotter and hotter. When I looked at the screen it showed constant data up and down. I wasnt syncing anything or surfing but it wouldnt stop. I shut down and restarted and even did the software "Battery Pull" but soon enough it would start data again and the battery would be eaten up. It was on 4G. Then finally it would stop an hour or so later. If I start the music app again it starts all over. Here is a thread on another site where we are trying to narrow it down. They think it may be the media server as it shows a lot of data usage!

Where can I get the Xperia X10i kernel sources for Android 2.1? And as it uses the GPL license so it must be available on request. I compiled the CIFS module on 1.6 but I really need it to recompile it with new sources. Also, kernel config file would be welcome too.

I have (as probably quite a few of you) upgraded my Xoom from HC to ICS (3.2.6->4.0.4). After the upgrade, I saw a massive battery drain and began wondering what was going on. I noticed the "Android OS" process was keeping the tablet awake through the middle of the night and I assumed it was the culprit.
Given that the Android OS process is part of the system kernel, I figured something went wrong in the upgrade. Flashed back to 3.2.3 Honeycomb from the motorola website, and did OTA upgrades all the way back to 4.0.4.
I left apps off, completely stock, locked, and back to the way someone would get it brand new. I did not install anything; and went to sleep for the night.
I woke up to about a 10% battery drain, the Android OS had used 80% of that 10%. Before ICS I was able to go 5+ days with moderate use on my tablet (Juicedefender and various other helpers), now I can barely make 1-2 days.

Nexus 5, 16GB, MRA58N (stock, not rooted). Sometimes the power percentages shown for each process in the battery monitor do not add up to the total battery drain? I am finding that sometimes they add up to within 1% of the total shown.... and sometimes they are WAY off with as much as 30% of the displayed battery drain unaccounted for. Since I don''t have access to the battery terminals, I can't determine independently whether the percentages shown are simply inaccurate, or whether there are missing processes (ie., processes not shown at all in the battery monitor).

I updated to WM10 10586.29 and now when my battery gets to 70% To 75% it will drain down do 2% in an hour. I have location, Hey Cortana and most background apps turned off and still get the drain. Also I just noticed while charging it takes forever, but when it get's to 40% it goes up to 100% in less than 10 min.

I don't understand what is happening with my 4 month old XPERIA RAY..I've changed the battery with the new one, switch off my phone and full charged it and when i've starded the phone the state of the battery was 96%. After 5-6 hours with data activated, no GPS, no WiFi, no Bluetooth the phones turn off (0%) Can't believe that's normal.When i've bought the XPERIA RAY, i've 2 days before my battery goes empty... And now the phone is heater than before.Is XPERIA RAY a big s**t like my first ps3?

It is correct that the android system on a brand new Xperia Z3+ uses 9.42GB of the phones memory. Surely this can't be right because it's only a 32GB phone it's not even one week old and it's telling me that 75% of my memory is full. How I can reduce the size of this file...

I just bought a brand new renault clio with the medianav system on board. Whenever i am streaming music over bluetooth to the car it has serious skipping issues. Like it will be practically unrecognisable as music, however if i pause and then play again it will work but there is always occasional skipping throughout the song. The thing is music plays fine over my bluetooth speaker at home so i don't think its actually the phone.
