[Q] Another battery thread but I am desperate

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.

[EXTREME BATTERY DRAIN OVERNIGHT] Possible fix and reasons

Hello
PROBLEM
Recently I have been facing issues with my nexus overnight battery drain. The battery drain is quite shocking (30-35% overnight). The irony is that using my nexus over two-three hours drains less battery than keeping it on overnight in deep sleep mode.
BEST SETTINGS FOR CRAZY BATTERY SCREEN TIME
I'm using 4.4.2 with elementalx kernel(2.12) with 800 undervolt, 1350ghz processor with 400 GPU.
I disable all double tap to wake up, slide to sleep features with all default settings except I use battery life extender at 4100mah (83-85% charge).
With these settings I have extremely good screen time over 6+ hours (I never calculated it but watching two movies of 4 hours only drain 32-38:victory:% battery with software decoder using headphones with MX player pro.
The reason for sticking with 4.4.2 is that on 4.4.3/4.4.4 the battery life doesn't reprpduce same for me.Also I face some ghost touches on latter updates.
On dalvik, I experience no problems on 4.4 to 4.4.2 but sometimes ghost touches on art which solve after a restart. In safe mode, there are no ghost touches in art!
Currently I'm on art.
APPS AND SETTINGS HELPING ME WITH GREAT BATTERY
I have greenify, wake lock detecter with Google search frozen(using titanium backup); location turned off, no NFC , no Bluetooth, WiFi only when required, sync on only for contacts, keep, chrome and I am using two gmail accounts.
All other apps like quick office, maps, earth, YouTube, newsletter, currents etc have been disabled! I don't leave WiFi on overnight!
All applications that require root are greenified/frozen until if required which is rare so I refreeze them afterwards.
All applications identified by wake lock detector are greenified! (Not using xposed framework to greenify system apps)
I use "show touches" on my device in dev options to keep track of ghost touches etc!
IRONY :
The irony is, android system and android OS drain about 9+12 % of my overall battery in deep sleep with my screen taking only 27% with over 13 hours time.
This means Google services are draining battery but I can't point out which on!
WHAT I'M THINKING OF DOING
I guess I'll update my Google play services and update with results! Version 4.4.52 is a battery killer !
Tried version 5

HUGE Battery Drain When Sleeping

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.

Massive wake lock and battery drain

Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s
Number of Wake Locks: 1
Byes sent: 246.21KB
Bytes Received: 5.70MB
App UID: 0
Wakelock Detail:
Google_C2DM 0.0s (1)
I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks

here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.

1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).

Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.

Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...

http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !

I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.
https://code.google.com/p/android/issues/detail?id=208324
However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence

There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.

S4-i337 battery drain via Android OS

Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.

It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.
