[Q] Android OS accounting for a huge part of battery usage - G2 Q&A, Help & Troubleshooting

Hello all.
First off, bear with me if this has been discussed before, I have searched on google and in previous threads here (including the amazing 58.5 hr standby and 6 hr. usage thread) but I cannot find the culprit of the huge Android OS drain.
The battery lasts about 4.5 hrs of screen on time , which is pretty neat but nowhere near what other people are reporting. I know the battery needs to go through a few cycles before reaching its full potential, but the Android OS drain is what bothers me. Please note that I am unrooted due to warranty issues and an unreliable rootchecker.
I have done the following:
Disabled bloatware
Disabled LG MIT (P.S Do you recommend me to change other settings from the hidden menu?)
Disabled auto sync and backup in the settings menu.
Disabled Google Location services from Google Settings, although I kept the location settings in the settings menu due to widget.
I installed Lux to prolong battery life and it only operates upon waking the device.
Installed BBS and Wakelock detector
BBS shows 154 partial wakelocks in just 3 hours of standby from WifiOffDelayIfNotUsed and NetworkLocationLocator 191 partial wakelocks.
Wakelock detector shows a fair amount of Facebook wakelocks (86 in 3 hours - could that be the culprit?) and Viber with 21 wakelocks. This makes me miss Greenify - damn!
To round this off, can anybody please give me advice on how to solve this drain? As previously mentioned I am not willing to root it just yet. Feel free to include perfomance boosting tips as well if you have any
Thanks in advance.

I don't know how to solve the problem, but I can tell you this regarding root: Flashing a KDZ file after doing a full factory reset makes the roottripper reset too, including a showing of UNROOTED in the download mode.

Awesome news! Makes me reconsider rooting my device. I would still want to know what I can do without rooting. Thanks a lot for the info ?

Use Better Battery Stats to see exactly what is causing wakelocks and GSam Battery Monitor to see what's using other things.
"A huge amount of battery" is meaningless without context. If it says "50%" but that's .5%/hr, it means NOTHING else was doing anything really.

Disable KnockON, then Android OS will shrink to a few percents in your statistics.
I have tested it out, KnockON is causing the most part of Android OS.
Via LG G2

Wifioffdelayifnotused can be caused by going in and out of service. Disable optimizing in Wi-Fi, disable disconnect on low signal, set sleep policy to never.

well. As stated in OP I am using BBS but I will try out Gsam battery.
You've got a point there, but I'm not seeing 24 hours of standby, which annoys me. A side note- if there was no' something' draining my battery wouldn't it show as "device is idle" rather than android os?

Thanks for the tip. I am well aware that knock on uses up some battery but I don't recall the people getting 6 hrs of usage and 50 hrs of standby disabling this feature. Anyway I wouldn't disable this feature even if it would give me am extra hour of usage (unless in dire need) ??
And to the last post (which I forgot to quote) WiFi is set enabled in standby and the other option is disabled. The only thing I have checked in the advanced WiFi settings is lower battery consumption when device is using WiFi. Thanks for clarifying though.
It seems like. Android os is a mystery ?

The cpu power consumption is the biggest problem~
I had read a Chinese thread that CPU quality is the major problem causing this huge battery drain. Qualcom classified 7 quality levels. Slow, nominal, fast, very fast, ultra fast,....from class 0 to 6.(higher is better). the higher class quality means that cpu can use lower voltage to reach higher frequencies. The difference between C 6 and 0 is about 0.15V,,, :crying:
PS: [email protected](0.95V Max)/ [email protected](1.1V Max)

There has been some improvement but the phone was awake for 42 minutes more than screen on time . I posted some screenshots.

I'd say leave wifi optimization, set sleep policy to any other than never, and turn off the feature that turns wifi off if the access point you're connect doesn't have internet access. Or try aosp

If you're connected to more Wi-Fi than cell signal, leaving this on will do nothing to increase battery usage, more so increase it. Counterintuitive, but it is what it is. This is Google software itself, not hardware. Learn before you post BS. The phone uses more battery searching and refreshing for 4G data signal than it ever will on Wi-Fi. Do what this guy says if you spend most the day in Wi-Fi, and watch those counts hit the roof. If your of Wi-Fi most the day, just turn it off until you are, all good. Why waste battery when unneeded.

Thanks for sharing info. in battery section, Can you also confirm what Region/variants/Batch/ROM version affected from this bug?
How widespread is this problem ?
Few Days ago cell standby : 80%
Now : ~44% after not using airplane mode in the night. Very sad about this issue because my battery life on my old Note 2 was really good

Turn off your gps and other background battery draining apps that maybe keeps your screen awake.
Your suppose to lose barely 1% during night sleep.

I m living in france, i have plk-l01 runing c432b100 build version.
Many users have the same issue...
It make me loose 25% per day, just for cell standby.
Even with aiplane mod active and cell broadcast disabled.
My screen consume less than cell standby :/

I am waiting for delivery but my model will be as for UK as everyone have across EU, This is very serious issue, I request all user to Email to Huawei/honor to they can release patch or update regarding that ASAP ? Can you tell me how much % battery drain overnight ? for example since when you turn off screen before you go to sleep to wakeup in the morning with or without dual sim and all bt, wifi & Mobile data off? Have try factory reset and see better result in drain ? Can you also measure Temperature when you wake up phone and when normal usage with Wifi and Mobile data using app. called CPUTEMP please
I loose between 5 and 10% per night, with airplane mode and w/o BT and wifi.
the phone stay cold.
I didn't wipe, but some users already tried and it don't fix.
I asked to honor to patch it, they know how to fix it.
I advise to get replacement, specifically ask them to give you different batch is possible, btw my 2013 LG G2 drain only 1-2% battery overnight on without airplane mode , try install CPU SPY and tell me your deep sleep % please

That doesn't mean there is a problem. It was reported in another review that cell standby reports high usage but it has no affect on battery life and they loose only 2% overnight. You could be losing high amount of battery overnight for other reasons, such as background apps.
i did many test, it's cell standby which drain my battery.

I don't thing that this problem should exist in Honor 7 as such not mention in Two dated review website like gsmarena.com or notbookcheck.net, if such a problem exist they must have mentioned in it, in the description of search result which say Description:
"When mobile data (2G or 3G) is switched on, all the internet apps continue to consume battery and keep the mobile data active unless they are force stopped. On kitkat, this didn't happen because apps stopped using mobile data whenever their transaction was over. But here in lollipop, they don't seem to stop ever and cause a huge battery drain.
Please look into this.. It's still present in 5.1 (aosp and all custom roms)."
The above statement means it confused your battery when you leave turned on Mobile Data or Wifi, There are so many app which terminate your application when you turn off the screen or even hibernate or stop until you use next time to stop battery drain even with Wifi and Mobile data off, I don't think any apps consuming battery or keeps CPU awake with Wifi or Mobile data off
Try installing "CLEAN MASTER" which will tell you any power and CPU hungry apps which running or restarting in background and also terminate or Hibernate apps when not in use with many more functions without ROOT
Can you also publish screenshot or battery usage and screen on time please
see here, many screenshot from different user :

Terrible battery life? What gives?

Hey guys...
Just here to say that I unplugged this phone at around 5 in the morning, and around 5 hours later its already down to 74%.
What did I do? Only about 10 minutes of mobile hotspot, a 2 minute phone call, and three text messages. The rest just idling...
1/4th of my battery life for just that?
What the heck?
Everything is disabled and the screen brightness is low... Whats the matter with this phone?
Looks like something is keeping your device awake.
Can you please add some screenshots of your battery graph?
In addition, you can try to boot into safe mode. If your problem is gone in safe mode, a third party app is interfering.
If you're rooted, try installing Wakelock detector or BBS (Better Battery Stats) and check out what is waking up your device.
If you use Gas Buddy, it was known to be causing massive bluetooth wakelocks. Either uninstall it or update it to the latest version.
Set your wifi to 2.4 ghz only. On 6.0 and 6.0.1, the 5 ghz band has been causing abnormal battery drain and keeping phones from entering doze mode. Here's the issue being reported: https://code.google.com/p/android/issues/detail?id=197460
If neither of these make a big improvement, you'll have to use your battery stats (and if rooted, use Better Battery Stats or Wakelock Detector) to specifically see what's keeping the phone awake. In either of these apps, filter the view by "Alarms" or "wakeup triggers" and you'll see what the heavy hitters are.
Be sure to go into Location>Settings and turn off wifi and bluetooth scanning.
Hi.the maps app isvuding WiFi and gps even though both are disabled and I'm not using it... Any ideas?

Battery Help

So I've had the 6p for about a month now and I'm absolutely loving the phone, but I have one huge issue which is the battery life. I read online that this phone is getting 6+ hours SOT, and every charge cycle I check my stats and I'm getting like barely 3 hours SOT. I feel like this shouldn't be happening and was wondering if anyone could clue me in on maybe something I'm doing wrong. I am rooted and running the latest Chroma and also using the latest elementalX kernel. I have Xposed installed which i feel shouldn't really be affecting battery life too much. I have amplify and greenify which should be boosting battery life but those are also not working. What I do on my phone is all day snapchatting, sometimes checking twitter and some would say heavy texting. If anyone could tell me why my battery isn't getting anything near the average it should be getting, or has any suggestions it would help lots!! Sorry for the long post, but i wanna resolve this issue
Hey, charge your phone to 100% (leave it charging for half a hour after it says that it's full). Then use it normally, and when it's almost empty, take screenshots of battery statistics and post here.
Also, what are your settings? Brightness, are you using 4G data constantly etc.
What I've read, Greenify messes up Doze.

Do you go off and on your phone a lot? Like check it, lock it, check it again? I guess stop starting would describe it? If so, then 3 hours is the expected screen on time for that usage. On constant usage you would get 4 hours+, for sure.

The screenshots could indeed be useful.
As you described, you use snapchat allot. Snapchat is a real battery drainer. It decreases screen time allot, because when snapchat is open, it enables both front and rear camera and gps and maybe even more things that I'm not aware about. So basically it enables everything thats power hungry on this device. If you want to keep snapchatting allot, I don't think you'll will get to 6 hours sot.
Maybe you can use a custom kernel. I personally use the latest Franco Kernel, that kernel has tweaked some stuff so the phone uses the battery friendly cores more than the power hungry cores, without having noticeable performance loss.
But as said a screenshot would be nice, maybe you can install better battery stats (it's on xda) for even more advanced stats.
And remove amplify and greenify, you get the same or better battery results, but keeping the phone more functional.

I never use 100% brightness usually only at about 30%-70%. And yes I am always using data as I need emails to be sync'd and have many social media notifications.

I've removed greenift and amplify, I'll post my screen shots once I get them Thanks for the help so far guys
Also try this:
Go to Settings > Location > Menu > Scanning > Wi-Fi scanning > disable
Go to Settings > Location > Menu > Scanning > Bluetooth scanning > disable
This was the first thing I did upon unboxing my precious.
So after doing what you guys told me to do I have gotten an extra hour out of the battery. Although yesterday I didn't use my phone as much as I usually do, due to being busy. Do you guys think this is the best its gonna get?!

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...

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.

maybe this help, on moto g this helped
apart from greenify and naptime...i dont think we have something like amplify yet for nougat devices, also with the governor scripts they are providing better results now
yep

LG G6 optimized for battery life

Hello, I am the new owner of the LG G6. I noticed a fairly large consumption of the battery in this phone, especially during idle
That is why I would like for myself and others to gather in this topic all the ways to improve the G6 performance in terms of battery life, which do not require rooting and are safe for the phone.
First, disable LDB (MLT in older versions) in hidden menu (LG 24/7 tracking of phone)
Search for "LDB function LG G6" in Google, there should be a theme on Reddit about MLT with exact instructions. Maybe someone below will drop the link, because I do not have such a possibility
What else can we do in the hidden LG menu to improve the battery life?
Second, turn off bloatwear
The easiest way is to go to settings > applications and disable (uninstall) applications that you do not use. However, this way you can not get rid of all the bloatware.
What are the other methods for improving the battery life of the LG G6?
Battery standby drain on my G6 (H870DS) is also poor. I lose between 1.5-2.5% an hour when the phone is just sat on the table. I have tried many things to reduce this without success. I have AOD off, battery saver on, gmail sync off, aeroplane mode on (no mobile/cell signal at home), Bluetooth off, WiFi off when screen off. I have removed/ hidden most of the bloatware using ADB commands and experimented with apps such as greenify and forcedoze but nothing seems to make any difference to the high battery consumption when the phone is idle. I have done 2-3 factory resets and nothing has improved. Gsam battery app tells me that a lot of battery usage is caused by android os, kernel and google play services. My conclusions are that android 7.0 Nougat has poor battery idle drain. LG will only update this to 8.0 Oreo eventually which might improve battery efficiency. Some people are reporting better standby performance with their G6’s so it might have something to do with which model/regions firmware you have. I also have the latest TWN firmware and this improved idle drain slightly. I shall wait for android 8.0 Oreo then factory reset and probably be disappointed. Great phone apart from poor battery standby and not having a notification led.
The most amusing thing I've noticed is that the Always-On Display has virtually no battery consumption. Whether it is running or not, I had the same high consumption on idle.
Tomorrow morning I will check whether turning off LDB (MLT) gives something.
I am afraid of updating to Android 8.0, because reviews of other phones after the update are extremely different, some say that the battery life has deteriorated, and others that have improved slightly
I too have my doubts that android 8.0 will be bring any improvement to battery standby drain so will be waiting to see other people’s experiences before I update.
This is also fun, because for the same type of device people report different effects of upgrades. So usually Android upgrade is a high risk game
It seems that turning off the LDB (MLT) feature has reduced the battery consumption in idle 2x, now the phone uses about 0.25% per hour.
Very interesting, that's the first time I've actually heard or read something about MLT/LDB. I wonder what both stands for and also what's its literal function. Polish forums are flooded with threads about "LG's spying app!".
I gave it a try and turned it off. Also I've turned off logging services too. After rebooting, I've removed two apps that are mentioned here and had to force-reboot again as "MLT has stopped" started popping up after a minute or two and it prevented me from doing anything on the phone
Hopefully it will improve battery life... even slightly, but improvement is improvement. For me, battery life is the weakest point of this phone (damned Android 7.0 and its idle battery drain bug)...
RAM is not so important for me, 4 gigs are enough and I've never experienced any slowdowns even with 30 tabs opened in Chrome
Someone on Reddit suggested disabling background running services for apps that use it for no real reason. This can be done by following:
Device settings > Smart doctor > Tap Memory > Tap overflow menu > Tap conserve memory
Selecting the apps that you want to not run in the background and setting the toggle to ON will help. Maybe. Ish.

Let me know what effects have turned off logging and uninstalling these applications. It is a pity that these applications can only be uninstalled on the root device.

Thanks for the hint. I just did it. Too bad there are so few applications that I want them to not work in the background

Manually turning MLT off should be enough, I removed these apps just in case but I don't think it makes MLT "double off" as it's already killed in service menu.
I will do some checks and report in few days, stay tuned.

Can you tell me how, step by step, you have disabled the logs?

I don't have my phone with me but as far as I remember the steps are almost exactly the same as for MLT/LDB disable.
Only you click the button about logging instead of MLT, one or two rows below. Then you have to tap "disable" button until every logging service below is set to "Disabled".

This option is called Log Services above the LDB function in the hidden menu. Unfortunately all these services I have already disabled :/
Another hint. Make sure that the built-in flash does not light when receiving calls and messages. You may not notice it, because the phone is always on the back.
This can be turned off: Settings> Accessibility> listening> Alarming flash
Tomorrow I will check how much battery I saved
My idle drain was over 60mAh per hour and over a day this was more than used by the screen. The Greenify aggressive doze helps, as does restricting mobile data in the background plus disabling all the bloat. Adding in the LDB hack has reduced idle drain to less than 40mAh per hour, not perfect but much better. To me it looks like LG thought the larger battery meant they could turn on all their rubbish and we wouldn't notice...
Going back to the subject, disabling the flash, acting as the notification light, did not bring about much improvement in battery life.

Every big smartphone manufacturer throws a lot of his ****. The most important thing is to optimize your Android overlay for battery saving. Not every manufacturer handles it satisfactorily

Thanks for the link. Some interesting information was in this video. The most interesting, because I've never seen it before, was to turn off Bluetooth scanning, which works even when Bluetooth is turned off.
To do this, go to settings> location> three dots> scanning> Bluetooth scanning
It seems that there are no hard and fast rules about this. Without any modification whatsoever on my G6, idle goes about 1% every 2 hours or so, even with light use. I'm running the v11d update of Oct 21. The update improved battery life that was already good. At the end of a workday, with bluetooth active and light to moderate use and a trip with Waze I typically have 75% left. It may be a regional issue with firmwares running slightly different apps in the background depending on where you are, or maybe difference in cell tower distances-- with a weak signal the phone radio powers up higher. Maybe LDB isn't used in my region (Middle East/Israel)
Are people using apps such as greenify, force doze, hibernation manager or clean master and if so what benefits in standby drain are they experiencing? Are these apps any good and do they create any problems of their own? From personal experience removing QuickMemo using adb commands improved my battery standby drain a little. What changes should be made in developer options to improve battery life such as animations or limit background processes etc. Nougat is set up to manage battery life in a certain way, so I just want to make sure I don’t make any changes or install any 3rd party apps that make my battery life even worse. What I have come to realise is that the G6 and the snapdragon 821 are not set up for efficient battery standby. Previously, I had a vodaphone smart ultra 6 (rebadge zte blade) with a 3000mah battery on marshmallow that would last upto 4 days on a single charge!
