Hey guys and please dont crucify me. I know there's a ton of other battery issue threads on this forum and on many others but I cant find the right one. I have looked up each and every one of them, about mediaserver draining the battery about the android system and so on. I have done everything each thread said to, downloaded greenify and hibernated most active apps, disabled and froze certain bloatware with titanium backup pro and so many other things. And I think that the battery would be supposed to perform at its best right now. I am not a very heavy user, I just use my phone for music, calls, a little gaming and the occasional facebook/messenger/browser session with either 4G or WiFi. I have everything everyone ever said turned off. Things like auto backup of Google+ and all location services and auto sync. Screen is constantly at 65% brightness. To further prove my point, at this point in this post which took me like 3 minutes to write, my battery has lost 3 percent. I can leave the phone unplugged all night at 100% and when I wake up it will be at 95% but the moment I pick it up and start playing some music or some games the battery goes down really fast. I can even compare it to the battery of my old Xperia S after a year and a half use which was like 7 hours altogether. Battery stats say that mediaserver takes up 20ish% battery and Android system goes over 40%. I really don't know what to do. Do you have any suggestions?
Thanks in advance, George.
you should look at the time it depletes when screen on, if its below 5 hours from 100% downward then its not good. I have noticed the battery still charges past 100%. So leave it an hour after it reaches 100%. I would also recommend using the charger that came with phone. No usb charging for these tests. Dont use phone while charging either.
Also freezing\debloating can be adverse, at least thats my experience on battery life. So I recommend going back to stock full clean with factory resets.
No recovering of apps or app data for these tests. No contamination so to speak.
Also lg roms allow you to switch off services via taskmanager settings, in settings app you can disable what you dont want to use. No need for debloating\freezing etc.
Switch off location settings, gps and bluetooth for this test. Search for carrier iq on lg g2 forum and how to disable it via settings. Switch of cloud storage(dropbox/box etc) and lg backup stuff. Only google accounts, wifi and mobile networks.
Now for the screen on time test, just use browsing apps. No games or music\movies.
Your screen on time should be 6 hours approximately. From 100 to 0. It can be 5-6 hours. If its below 5 then its not good. this is with good network coverage btw.
thats what I would do

Have you tried better battery stats, wake lock detector, or even gsam battery monitor. Maybe you have Google location services on?

Yes I have tried all of the above. Only thing that sticks out is something called 1013 which keeps running and waking my phone but I think it's something about the sound. Next is Android System with many wakelocks and as I said with 30+ % battery consumption. Everything location-wise is off. Actually everything is off. Every setting. Things go to hell when I open 4G or WiFi. Also I have the international model so I don't think there's carrier IQ in my device, or maybe I didn't find it in an app suggested by someone here for that purpose. System Tweaks I think it was.
Could you post a screen shot?

I've had android 4x do this on multiple devices, multiple roms for no apparent reason. Wipe it and start over. Wipe everything. Especially directories with any form of music, sound files, videos... ( Use LG Flash Tool and go back to stock 4.2 for example will do just that )
So the OTA came over to my country and now it seems like BBS and WLD are broken. Can't really do anything to show you the more complex battery stats and can't really say that the battery has improved. Reducing the brightness did have some effect but I am not really fond of having it at such low values. Anything else I can do to minimize the Android System battery consumption? Its bigger than what the screen is using, even when it was at 70% brightness.
Sad to say my first LG G2 just got replaced today & am now running into this problem with the 2nd phone. Its literally night and day battery life performance between both phones.
First phone had 0 issues and by now I'd still have battery % in the 90s. New phone is sitting @ 63% after 3 hours of use (setting up phone, few reboots here there....just factory resetted for the 2nd time to try and clear this etc)
Culprits are:
Google Services
Android Core Apps
Media Server
System UI
Both phones are: 4.2.2
build: JDQ39B
Software: D80110c
brightness (which never was an issue)= 45%
O.P,
has your situation improved or worsened since you've encountered this problem? I'm thinking about sending my replacement back for another replacement

I can now say that the battery life of my phone has improved. But sadlyf the problem was probably some corrupt mp3 files that I moved directly from my old device which forced the mediaserver service to run constantly and thus the android system. :/ I still can say that I think it drains a bit fast when I use it for browsing, Facebook, games and stuff but at least when I check the battery consumption, the only things stated there that make a difference are the screen at ~30-35% and the game which I was playing or for example Chrome. It finally feels like that whatever I use drains the battery and not something else in the background but I don't have that good of an impression for the 3000mAh "beast" battery of the G2. Awesome phone though.

I ended up returning my replacement phone and am back on my original G2 until I can get a proper replacement. I can tell you, the G2 does have an awesome battery life if you get a good phone out the box.
The differences between my first G2 and the 2nd one tmobile sent me are night and day. Get a replacement phone while you still have time.
Should have my new one next week. Just hope it's exactly like my first one.
Ex....been using it all day..I mean heavy usage...and in still @ 75%..and the phone is cool to the touch
The replacement g2 would [email protected] 36-37% by now and running hot

You're on 4.2.2, not 4.4.2 when you have the 1013, is that correct?
Try rebooting when the volume is on, rather than rebooting in quiet/vibrate mode.

The OTA came to my country some days ago. Still the battery feels kind of small. Is it normal to lose 1% every ~1-2 minutes on 4G browsing? With nothing else on. No gps no G+ backup no anything.
Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.
I got a S4 i9505 with albe95 S6 port ROM. I've tweaked the settings to pretty much disable all background activity so there's no syncing, no GPS, no bluetooth no NFC etc. I've got airplane mode on 24/7 with WiFi turned on. I've also installed Greenify and System Tuner Pro (I have root) and disabled a few GooglePlayServices services and stuff. Followed a tutorial for that. Looking at the settings app, I've got 40% battery remaining and have been on battery for 2 hours 40 minutes. Probably slept for 30-45 minutes and when it was on, I go on chrome, mess with Theme engine and some other light stuff. Now I just waited 20-30 minutes and it drained 4% screen off. I waited 5 minutes and it drained 1%. Is there an app that runs in the background and I leave my phone screen off overnight to tell me what processes are using the most battery and then disable those processes? I've tried to google it but none have helped. I've disabled Gtalk and a bunch of other processes, no luck. About to download Titanium and mess around with Greenify a bit more. I'm new to Android, reason I don't like Android is it's battery life. My iPod touch 5's 910mAh battery lasts 5 hours watching YouTube, surfing the web and light gaming (Clash of Clans) while the S4's 2600 mAh battery lasts 3-4 hours. Triple the size but less battery life?
Android's root is a lot more complicated than iOS, we just go to Cydia and download tweaks like an app from the Play Store. But yeah, any apps you guys use to check background processes using battery?
It's called BetterBatteryStats.
I don't think you will find it on the play store. Or if it's free there. There is a free version on the forums here. And I mean free, not cracked or anything.
And there's more to battery life than just mAh. Your iPod has a smaller screen and a smaller resolution. Which means less work for the GPU.

Right so I messed around with BBS and I discovered the different tabs. Looked at Kernel wakelocks and Partial wakelocks. Did some research and PowerManagementService is a big one. Was told to go to partial wakelock and found RILS and RILJ0. Did some more research on that and it's related to radio and wireless stuff. (Radio Interface Layer) Did some MORE research and apparently my modem is the problem. Someone suggested me to get "GetRIL" from Play Store and see if the two ... things match but GetRIL either isn't compatible or it doesn't work. Now problem is, I have Airplane mode on 24/7 and WiFi enabled so cellular should b turned off, right?
With airplane mode on yes, network should be turned off.
The modem can be changed anyway. So maybe you just have to update the modem.
Also try a different rom.

I read that ROMS and kernels have no affect on battery life other than disabling sync and background stuff in the settings app. Only time it will affect battery life is if it's badly written.
So if cellular is turned off, why is "Cell Standby" the second most draining thing behind "Screen"? All the websites I looked at just say "Turn airplane on and wifi on" but what I'm really looking for is to completely disable cellular with "System Tuner", or do something with root permissions to force stop cellular. I've got no SIM card installed.
Not true. Both kernel and ROM can have a significant effect on battery life. For the kernel, a custom kernel can improve battery life by allowing the processor to be undervolted, thus using less power per CPU cycle. The ROM could also have battery-saving features, e.g. Doze in Android 6.0. The ROM could also have battery-sapping bugs.
The modem is separate from the ROM and kernel. It will have its own enhancements and is updated frequently, so you should update it.
If you dial *#*#4636#*#* you should get to a menu where you have the option to turn off radio. But that's probably the same thing as airplane mode.
And roms and kernels do have an impact on battery life. I once flashed a kernel that drained my battery very quickly. The same rom without that kernel was fine and with great battery life.
So, as I said, consider changing your rom. Just to see if it is rom related or not.

I updated my modem and bootloader from the same thread as my ROM, not sure if it did anything but I've managed to raise battery life from ~4 hours to ~7 hours just non-stop google chrome, theme-ing, downloading apps and trying to get better battery life. Also watched some YouTube videos.
I actually flashed this ROM because of themes, specifically the Avengers theme. Also there's a few pure black themes, did some research and pure black actually gives your battery ~40% more juice. Real world usage will probably be at least 15-20% more battery. But I'm still trying to find out how to fully disable cellular, anybody know? I've got root and Titanium Backup. I'm not sure what to freeze though and "Cell standby" continues to be the second most draining thing in the settings app.

Dialing that says "Not registered with network" because I have no SIM installed. Cellular would kill my battery but even without a SIM, cellular still is active because of emergency.
I've googled everything I can think of, within 2 days I've increased my battery by at least 60% but cellular is driving me nuts. It's using ~20 of my battery while using my phone, that's 20% plus another ~20% once I find a way to get a pure black theme that works in third-party apps as well for my AMOLED display. Also, titanium backup isn't able to convert Google Play Services or GSF into a app so I can greenify it. It just processes and processes.
There is no theme that can make all apps black. Dark material makes many apps pitch black, but it's for CM based roms only.
You can get the pro version of greenify and maybe xposed. Then you can greenify system apps. Including Google play stuff. But greenify works only when screen is off. When screen is on, the greenified apps will run again.
Or use titanium backup to freeze everything Google play related, until you need it. But doing so will require you to input your gmail account again.
You might also freeze the phone app and anything else related to network. Since you're not going to use the phone for calls. Maybe that will solve cell issue.
Right, I have no idea how I did it but my phone for the past hour and a half has not dropped a single percent and has mostly been in deep sleep. No more wakelocks too, only thing I noticed was a alarm from Google in BBS but didn't mind that too much. Excited to see how much it will drop overnight.
Also, do you know the largest battery for the S4 that I can buy on amazon.ca? I don't want a case or a separate battery, I just want a battery that's more than 2600 mAh. So far, I think the ZeroLemon 3000 mAh battery is the biggest but I heard it's got no NFC. I don't use NFC or anything wireless other than WiFi but could you give me a quick explanation of what this does cause apparently it's a part of the battery itself.
You know that thing where you put two phones together (back to back) and it transfers data from one phone to the other? That is NFC. You can basically send web pages, app pages in the google play store and phone numbers with it. Just bring whatever you want to send on the screen and touch your phone on another phone to send it.
You can't sent actual apps and files.
The connection is established through connectors on the battery. That's why it won't work if the battery doesn't have one. It also is a method to verify the autenticity of batteries. Fake batteries don't usually have working NFC.
Now, the biggest S4 battery I heard of is about 9000 mAh. The second is 7500 mAh. I don't know if you can find them on Amazon.ca.
Use amplify and limit all "safe to limit" wakelocks.
No Bluetooth, No Location - Yes WiFi, LTE 100% signal coverage, no downtime, overall low brightness around 25-40% I can't seem to get past a day of regular use with 2 hours and half average screen time. Using latest OTA.
I've turned off the always-on screen, several bloatware that came preinstalled, including Facebook and Whatsapp.
The first on the battery usage is always Android System followed by Cell Standby then Android OS (again???) and then Screen. Also the voice call seems to use some great amount of battery. Naming might be different since my Android is in another language.
Have turned on energy saving for most apps that runs on background. Doesn't help much since I don't have many apps that runs on background. Imagine if I did! My day ends with about 20~27% battery left, I just turned off fast charging to see if it helps anything. My Xperia Z3 with Whatsapp and a great deal of apps installed would end the day with over 50~65% with Stamina Mode. I know the screen is smaller but so is the battery.
So I thought it would get better with time but it didn't, it's the S7 Edge Exynos Single SIM, unbranded with the official Samsung rom so I could get the latest updates or I would be stuck with no updates at all since Frebuary, since my carrier usually only releases major OTAs such Android N and skips all the minor updates.
Yes I did a factory reset already hoping for the better, maybe I got a defective Galaxy S7? I'd hate to have my phone fixed and the battery changed, it wont be the same again unless they give me a new one which is unlikely.
Why is Android System and Android OS draining so much battery? Are there any tools to debug this and trace which processes are using CPU time? Or could this be due a faulty battery?
Settings, Applications, Google. Disable all the services that will cause wakelocks such as all security options. This is something 99% of folks overlook or forget. Post a screenshot of your battery stats

That left me with 49% battery. Not sure how great the results are considering the brightness was very low.
Since the image took the whole page, here are the links instead lol.

Dont quote me on this but I believe the Android System drain issue is a byproduct of the latest Samsung firmware update...
Someone more in the know could correct me or elaborate more

Just some heads up, in offline mode my phone went a full day with a 6% drop, half hour screen time and some minor gaming, when I turned the phone radio back on around 20:00 when it was 10:00AM it was down to 15% battery, solely on standby. No bluetooth No location - Yes Wireless Yes LTE
I have now had my galaxy s8 for over a year and i have noticed my battery life hasnt always been that great.
I have noticed that over a total day i only get 2-3 hours screen on time.
For an example when i go with the bus home for 25 min my battery often drains over 10% without even using the screen for 25 minutes.
Once i installed another rom called lightrom or something over the renovate ice rom and it got much better the first day but second day when i got more apps on it begun to be bad again.
I then went back to renovate ice rom and i was back to bad battery life again when i installed all my apps.
BUT in this case i have an app called greenify and i greenify all my apps in the background but i still have a massive standby drain
I have never found out what has caused my problem but for sure it cant last a whole day
I have this thought that it can be weak signal but i have disabled the option "Keep mobile data turned on" and followed multiple tutorials of how to make battery life better
AOD off, Location off, Wifi off, bluetooth on ( for gear s3), nfc off,
So i only use bluetooth and mobile data.
I apreciate all help

Since the problem starts when you install your apps, I would start with checking which apps are the culprit. Apps like snapchat and Facebook are notoriously known for unreasonable high battery drain in standby.

Personally I have auto sync off, no battery saver, amplify, and display set to WQHD but I also use dark themes via substratum and my average battery life is roughly about 8 hours SOT
Edit: Sorry meant to quote OP

I have deleted Facebook a couple of weeks ago and that made no huge difference. Though I think snapchat may be the one. But I often have it hibernated
