Hey guys,
I am having a huge battery issues. I am using Slim Bean ROM right now with Yank kernel, however before this I used a newer version of Jellybean CM10.1 and the problem was the same. Before going Jellybean, on ICS, the problem was not there however.
So when WiFi is turned on, "Android OS" eats a huge chunk of battery when the phone is sleeping. It does not always do this, however. Sometimes the battery curve falls slowly, which I would consider "normal" and the same way it was as I knew it f rom ICS. Then randomly during other times, usually after using the phone and doing something with it, the battery curve will suddenly drop drastically even though nothing changed. I'm gonna post some battery screenshots with explanations. I'd be very grateful if someone could take a look and try to see what's wrong.

As you can see here, Android OS takes up the hugest chunk of battery.
The CPU usage and keep awake time is extreme, especially considering how it used to be before that (comparison pics from other ROM are at the end of post).
The screen is barely accounted for any battery usage with as little as 3%
BBS says this:
No idea what any of that means, but I do know that the problem is with WiFi. If I turn it off my battery lasts forever. I even tried using Juice Defender for a little while to only periodically turn on my WiFi every 30 minutes, and it did solve the problem, however I can not keep using Juice Defender as it will always automatically turn off WiFi when the screen goes off, and that is troublesome when I am making calls on Skype or Google Talk. Wakeups which I do not know what they mean, at least the top ones. Seems to be something about the Android OS itself.
And here is a recent picture after again charging to full, where you can clearly see that the problem persists. The slowly falling curve in between the two steep curves is how I expect it to be. However I do not know why the curves suddenly become steep, after pressing the power button to do little things such as checking the time on the lockscreen. I mean it's normal that once I turn the phone on the curve will go down because the screen is on, but I turn it back off right after, yet the curve keeps falling as if I was keeping my phone turned on. Please note that all this time my phone is being in sleep mode 95% of the time, it is not being moved out of WiFi range or anything, it ist just laying there and doing nothing, other than I turn on the screen every now and then to check notifications, not very often though, which seems to trigger the problem. I also made sure nothing is running in the background by long pressing home button and ending everything. The problem whether the sleep-curve with WiFi falls "normally" or "broken" seems to be completely random.
Also last but not least, I will post screenshots of the ROM I used before, CM10 ICS, where the difference is clearly to be seen. This is how I want it to be again but I don't know how.
Here you can clearly see how Android OS uses WAY less CPU and keeps the phone awake for only a fraction of what it is above, even though the way I use it is exactly the same. WiFi running 100% of the phone uptime, with minor usage, and the screen for majority of battery usage just as it's supposed to be. Yes the total phone life is about the same, however the big difference is that as you can see on the last pic I got 3h30 screen on time so basically triple as much as with the problematic battery curve.
I'm really clueless here, I have done several reflashes of Slim Bean and updated the Yank kernel, I also used the official Slim Bean kernel before Yank that still had the exact same problem. I really don't know what causes this other than it somehow has to do with WiFi and Android OS. My only guess is that Jelly Bean works differently with WiFi but it still shouldn't be this extreme as far as I know.
Any help is greatly appreciated. Thanks guys.
EDIT: Problem is fixed, see following post for solution: http://forum.xda-developers.com/showpost.php?p=37987244&postcount=8
first of all may of the photos are unavailable.
the ones that are available looking pretty good over 36 hours working with 3.5 hour of screen on.
as for the wifi you can limit it to work while "sleep" only when connected to charger via advanced under wifi settings.
Ugh, I hate Dropbox. The pics worked for a while but something is weird. I'll upload to another host and edit. The thing is I don't consider it a good running time since the phone is in deep sleep all the time, if I'd use it normally it would probably be dead after like half a day. The one with 36 hours with 3h30 screen on was the one before the problem occured, so yes I agree that's a great battery curve however it is not like that anymore sadly.
Pictures are now working, sorry for that. Any help is really appreciated. I want my old awesome battery curve back! :crying:
Come on guys can't anyone help? Do I really have to go back to an old ROM to fix this? Are there any settings in routers that could cause this?
You are confused, as in not understanding what the "Android OS" usage means. It is the percentage of battery used, not battery use. Since you did virtually nothing with your phone, it is the highest percentage of that "nothing".
Perhaps you should research more...? and actually use your phone as intended and let everything settle.
By the way, it is difficult to follow the various screenshots and deduce what you are trying to show, so some or all of the above comes with a caveat.
sorry for not replying threads get down quickly.
anyways @LenAsh gave you the answer that probably i would give you after seeing the correct pic's.
BTW, i suggest for next time to reduce the pic resolution or attach it or link to it cause it makes your post uneasy to read.

Did you not see the curve? Regardless if I use the phone or not, Android OS should not have such a high battery consumption and CPU/wake hours. It is broken. There is no need to brush the problem off as "nothing" if you looked at the curves you can see that there is a problem because the curve does not drop steadily. If I barely use the phone, screen on should have the majority percentage of the battery consumption.
Anyways, after two weeks I think I have finally found the solution.
To sum it up:
Symptoms:
- WiFi keeps the CPU working and the phone awake
- This is shown through high "Android OS" battery usage percentage
- It is also shown through BBS with wlan_rx_wake being on the top
- The CPU will work at 200MHz most of the time when you turned it off, instead of being in deep sleep as it's supposed to
- Your battery curve will not fall steadily, the problem can be triggered randomly by itself, or not appear at all for a while
- This seems to be a problem within the Android operating system itself, not with the routers, because using a Windows Mobile or iPhone on the same network/router does not have the same problems
Problem: depending on your router, the Android OS can bug up and keep sending queries because of DHCP. This prevents the phone from going to sleep properly when WiFi is on, and causes extremely high CPU usage and wake times when the phone is supposed to be in deep sleep.
Solution: If you have a router that allows for it, give your phone a static IP while allowing the DHCP server to automatically assign IPs to the rest of your hardware (Asus N56U allows for this, for example). If your router can't do DHCP and allowing statics at the same time separately, the only solution is to turn off DHCP completely and assign IPs manually to all of your devices. If you are connecting to a network that is not your home network, and you have no control over the router/hardware, you can't do anything about it unfortunately.
I think this problem and solution should be added to a stickied FAQ somewhere, because I can tell from personal experience that it's extremely hard to analyze the problem and then google for a solution. There are many threads about it all over the internet on several forums without a solid conclusion, they just get buried. Most advice doesn't help and will just waste a users time such as "reinstall ROM" or "turn off your WiFi".
I'll edit the original post and resize the pictures. I hope this thread now has enough keyboards for google searching, maybe other people who have the same problem will find this thread and the solution easier and it will save them the hassle of wasting hours to find a solution like I did.
Thanks for the help guys.
Original post is updated, this will be the last bump of myself in the thread (unless other people have questions and I can try to help). Hopefully this can be used as a source for other people having the same problem.
Cheers guys! :good:

Thank you so much for your time and effort!
My phone was getting very hot and the battery life fell to 6 hours for me all of the sudden. Switching to airplane mode solved the heating and battery usage and that info pushed me in the right direction for finding the solution - your post.
bah I never saw this thread first time round. I could have given the same answer about static IP addresses without all the delays. Sorry.

Same Issue... 90% Andorid OS... i provide a picture from wakelock... can u help me out pls ?
The truth is, that this problem never goes away, once youve got it. I had it from almost the very beginning on my N7 and I tried literally everything, including this method here - nothing helped...I never really believed in this method,tho, cause the problem occurs with WiFi off, too. I dont know what causes this f*ing bug, but everyone who has it, just has to learn to live with it, or buy a new device.

This is just ridiculous... All I've been doing is browsing xda... everything else is turned off.

I know the screen is turned up, but thats no excuse, my tf101 manages at least 6 hours at the same brightness.
What the hell is going on - where is that improved battery life I purchased?
Something else is the issue. That is very uncommon. No reason it should've drained that much. Even if it is a new device needing battery to go thru more cycles. I'd say try a reset. Maybe your battery meter reporting false info. No way balanced with super ips mode would drain that much just browsing the web. Unless you have some app or widget that draining like crazy. How long have you had this device? What was the last apps or Widgets you downloaded?
Surfing the web does drain the battery the fastest next to display. Plus watching flash videos is a major battery drainer. I'd say check for rogue apps. You can also download better battery stats to see what has really nbeen draining battery the most. I easily get 9-11 hrs of battery on balanced mode doing more than you did.
First of all, the TF101 does NOT have the same screen brightness as the TF201.
http://www.notebookcheck.net/Review-Asus-Eee-Pad-Transformer-TF101-Tablet-MID.54258.0.html
http://www.notebookcheck.net/Review-Asus-Eee-Pad-Transformer-Prime-TF201-Tablet-MID.69849.0.html
Average screen brightness of the TF101 is 331.6 cd/m^2 and the TF201 is 484cd/m^2. It's almost FIFTY percent brighter at maximum brightness than the TF101.
The TF201 at 50% brightness has a cd/m^2 average of 305. When Super IPS+ mode is used a maximum average of 514 cd/m^2 is possible.
I'm not interested in a reset at this point, but I am going to download a battery analysis tool because this is crazy.
The last apps I downloaded were an irc client and a like 2 games.
The battery life has never been fantastic - but this is just bad. I've had it about 10 days now... gamestop unit so no returns.
There was no flash, no sound, just web and nothing more.

Your telling me.. I have them right next to each other and there's no noticeable difference between the two...
On .15, I've been running about 15%/hour on heavy browsing, video, gaming (although heavy gaming can push 30%/hour), and about 7.5% on things like ebook reading, light browsing, etc. Standby has been about .375%/hour, which is excellent.
So, the OP's results are an anomaly, clearly. I'd say, do a complete shut down and then restart, and see what happens. Has to be some kind of rogue app or system component causing this.
GAmestop has a 30 day warranty exchange program. If you want you can easily exchange it for another if the battery life doesn't get better. What you reported is something unheard of before. Never heard a battery draining that fast. Better battery stats is the best for battery analysis.

An exchange may help - would be a pity though because I have working wifi and gps w/ 0 lightbleeds. I was considering virtuous, but i haven't unlocked the bootloader yet.
I honestly don't feel a factory reset would change much... maybe its just. 15.

Waiting for a complete discharge first - then I'll charge it up and see if this continues.
here's what bbs says so far if anyone is interested. I haven't updated Boat browser lately so I don't know why it wouldn't have done this before if that was the problem.
Battery still new if only 10 days old. Do the complete discharge like you said then charge up again. I don't think it really needs to be exchanged unless the poor battery life continues. Boat browser is your culprit. You could try switching to another browser. Boat browser might drain more power than others. Try ICS+ browser or opera mobile. I use those n get great battery life. Always make sure your apps are up to date. Updated ones more optimized.
I hope it's not boat D;

I really think you might have something else or a few things running in background you not seeing. Another way tl see is load up the Asus task manager widget. See if any odd apps or anything is running. If so, kill it. Also, make sure you put display to sleep at least 1 minute or less. I have mines set on 30 seconds or sometimes 15seconds. Which means if no activity detected in that time frame, screen will cut off. This can dramatically improve battery life. Also make sure to cut down the frequency of notifications. I have my mail set to 1hr. Which is the Max or longest interval. Or you could cut it off and have it update manually when you open mail up. Also check to make sure you don't have apps that syncing too often. Like Facebook, etc... this can be found in settings. I city my Facebook notifications off. It goes off too much. So instead it'll update whenever I open up the app. Lots of things you can do and check to optimize battery performance. Also live wallpapers can drain. I don't use them. Then its best to leave auto brightness off. Better battery life can be had using manual. Plus even if ips+ is off but still on Max brightness, it'll drain battery fast. I never have my display more then 25% with ips+ off. One thing you can try is to put brightness all the way down. Then cut on ips+. The display is bright n will drain less than cutting brightness all the way up. Someone posted good battery life with that setup. I'm still testing it out.

Will 1 hr notifications affect google voice notifications as well?
Not sure. Don't think so. I think you can set Google voice notifications frequency within the app itself.
Still getting the exact same results 1 hour and 40 mins into a fresh recharge.
I uninstalled boat browser and reverted to stock - stock is draining at the same rate.
I want to try a factory reset - but I really don't want to have to install everything and get it configured right again :/
considering unlocking the bootloader so I can make a nandroid backup - but its risky if its a battery problem instead of a software one.
I ended up getting 5 hours and 6 mins total yesterday after switching power saving halfway throufh and cutting the brightness 30%.
Don't risk warranty unlocking. I honestly don't know why you getting subpar battery performance. Most seem to gget great battery performance. Try a factory reset through settings or stock recovery mode. So it can clear all old data or any bugs might be prevalent.

I'll give it a shot tomorrow night when I get home from college. I installed juice defender ultimate so I'll give that a go in the meantime.
if I factory reset I'm probably going to revert to honeycomb with stock firmware because I have a gut feeling its .15 and ics is only hindering some of my apps from working at the cost of a nicer ui.
As I said I have working gps/wifi so the firmware updates aren't doing me any favors.

I have mines set to always n still get really good battery life.
Op, I heard apps like juice defender n such don't really do much for tablets n may actually cause more battery drain. Reason because depending on your settings in that app, it'll constantly be trying to kill or shut down processes that'll pop right back up. Plus killing of certain processes might cause issue or more CPU strain. It'll be better to just freeze them. Just something I read here on xda. I think of was in the tips & hints section of better battery stats. They said not to use apps like juice defender n such.
Just like the title says, after 5 hours of light usage my prime factor for battery drain is CellStandby at 42% (the phone itself was down to 70%).
Anyone experienced this so far? I'm aware that LTE is rather demanding but it can't be that bad vs HSPA which drained next to nothing on standby

It's a bug in the software.
Thanks, I did search (albeit quickly) in the forums here and didn't see any mention of it.
I did see an article about the international model being affected by a similar glitch so.. all models would have this ?
I've had the phone for 5 days and gone through maybe 8 batt cycles. I'm not getting more than 2hrs screen time on any cycle. This is stupidly horrible battery life. There has got to be something severely wrong. I don't do much with the phone. I can't even with less than 2hrs to work with. Overnight batt loss is maybe 8%.
Any help is ENORMOUSLY appreciated.

I believe all have this bug. It's just that, a bug. And there is a fix, but I'm too lazy to apply it. (Assuming it works to fix the bug in the U.S. variant software)
I'm on HSPA with TMO but it seems to depend on reception more than anything in my experience. Here's my log from today:
Lol, sorry for the huge image
a bug as in it isnt actually draining the battery or it is really draining it?
I'm in the same boat, and there is no way that the standby is just a calculation error. If I sit and use my phone continuously after charging I can get 2 hrs of screen time while the battery drops from 100% to ~65%. During a normal day of light use I completely drain the battery and my screen time might be 1h50m at most. So something is definitely up - although I'm also getting terrible signal strength, and I think that might have something to do with it. I've searched every thread and have made sure that I have no rogue apps or processes consuming the battery either.
gary
edited - I take it back, after restoring my phone last night I have gotten 2h25m screen time after 11h45m since charging and I'm at 17%. So, doing better but not great by any stretch.

Hi guys
This seems to be an issue on all SGS3s. I have both the LTE and international model and they both show high cell standby. Check this thread out for more info on the i9300 forums to understand why its showing so high which is actually a calculation error
http://forum.xda-developers.com/showthread.php?t=1732722
My i747 is rooted so I decided to make a backup and flash the zip fix they provided and seemed to work. But the risk is inherently yours if you want to try it. Its just an xml file so I wasn't worried trying it in my case. I am more sending the link so you can see why it reports using so much battery
My cell standby battery usage went from over 50% to 5%
Basically, cell standby is not really killing your battery, it overestimates the power usage as being 10X more than what it is from my understanding

Yes yes yes! This is exactly my experience too! There must be something wrong if all others report 4+hrs screen time and we can barely break 2hrs. I'm in San francisco. My previous atrix "4g" would do at least 3hrs during my day to day.
Please, help. I'm really sad. Was really looking forward to at least an extra 30min over the atrix in my day to day.
So is the battery actually draining that fast with the cell stand by issue... Or us the battery actually higher charge than reporting?

Are exactly the same thing I'm also experiencing. I've come close to taking it back and exchanging it for another one but I'm not sure if this is how all of the US versions of the S3 are. Been reading through threads here and posted on a few of them and it looks like short battery life is a pretty common problem. I hope someone comes up with a fix pretty soon before I run out of time to exchange or return it.

You are close, but not exactly right.
When writing the software one of the developers entered 34mw for how much the battery should drain at standby instead of 3.4mw. A simple typo, but im sure if there isnt a fix already that there will be soon :]

There's a fix that's available on this forum but that only fixes the reporting. It doesn't fix the poor battery life.

So something is definitely up - although I'm also getting terrible signal strength, and I think that might have something to do with it. I've searched every thread and have made sure that I have no rogue apps or processes consuming the battery either.

edited - I take it back, after restoring my phone last night I have gotten 2h25m screen time after 11h45m since charging and I'm at 17%. So, doing better but not great by any stretch."
Are exactly the same thing I'm also experiencing. I've come close to taking it back and exchanging it for another one but I'm not sure if this is how all of the US versions of the S3 are. Been reading through threads here and posted on a few of them and it looks like short battery life is a pretty common problem. I hope someone comes up with a fix pretty soon before I run out of time to exchange or return it.

Should we start a new thread? I've been posting in all the various battery threads to avoid getting yelled at for starting a poor battery issue thread. You're the fifth person to note the same issue. I too restored my phone this morning and it seems to be doing better, but still nowhere near what others are reporting. Also not nearly on par with my previous Atrix.
Maybe we have valid reason to start a new thread?
I applied the fix but still have poor battery life. Just as bad if not worse than my epic 4g.

CDMA people make sure you post your carrier when discussing battery life. GSM battery life for me hasn't been too bad. 10 hours constant use or so on wifi and around 6 hours or so on hspda. Standby time is very good. Especially for stock kernel.
I'm sure we can get some more once the LTE switch gets added.
That fix is just for the calculation of cell standby drain, not for how much it is actually taxing the battery. Several people on AT&T seem to have a real problem with excessive battery drain in standby, and (for me at least) it seems like it's happening when I have a poor signal. Unfortunately, that is mostly all of the time.
I found this old thread, and the APN listed there seems to help. It's just an interim solution though and I have to imagine AT&T will have a software fix for us soon.

I have i9205 for 1.5 week. I rooted it after a few hours I have it. I was in rooted + official rom for a week. Then I flashed Cassies XtraLiteROM to it a few days ago. XtraLiteROM is based on official stripped down to minimum plus some tweaks.
My observation of battery drop during the night (wifi/3g/gps/bluetooth all off) is indistinguishable between the official rom and XtraLiteROM. About 10%-12% drop during the 8-hour sleep.
I greenified facebook app and a few others that I think works in the background. I tried to invoke Wakelock detector, hoping to find something. It appeared normal and said 8-hour deep sleep. The battery level falls continuously and smoothly during the sleep with hardly any wakeup.
Is it common with 4.2.2? I have another LG L9 rooted with 4.1.2. The drop during the night is 1%-2%.
I left my mega all stock. No root or any modifications and when i go to bed i put it in flightmode and it loses about 1% or 2% in those 8 hours just like your LG

I'm also having the same battery drain problems since the first day I bought Mega 6.3. I have tried different ROM versions UAMEA,ED,F2,G3 and now the latest G4 but still having the same problem. Today I lost 3% in a matter of 1.5hours without even doing anything on my phone within those times. Flightmode technique you mentioned seems to be good but the problem is we may not be able to receive emergency or urgent calls/text while asleep. I was hoping samsung would address this drain bug.

But the problem seems to be present even if you don't install anything else than what is supplied !!
I don't understand what's going on with the battery:
one day you put the phone in arplane mode and for 10 hours you eat 1% of the battery :good:
The next day without changing anything you eat 10% in the same conditions WTF !!
As far I can see it seems that there is a problem with the release 4.2 (problem also for the Galaxy S4).!!
In another forum i participate, some people had similar issues, they had been harrowed down to some programs they were running. some people had Mega synchronise their photos every time they connected to the internet others had some other crap going on. if it was a firmware issue, everyone would have it. i, for example don't have this problem. you can try to use Disable service program to see which services are active in the background and are eating your battery and stop them carefully.

For example phone in airplane mode everything off (air view, NFC, GPS, synch off etc):
From yesterday 23.00 till morning 09.00 lost 11%
From 09.00 till 14:00 lost 4%
From 14.00 till now (23.00) lost 3%
Without touching the phone !!

You've got me all wrong. I'm talking about installing stock ROM (latest version) without any modification i.e. root, cwm, etc and no other apps
installed except samsung built-in apps but still battery drains like hell overnight with almost everything turned-off (wifi, bluetooth, gps, rotation sensor, etc.). So your question is a little bit off topic.

No, not really, because the stock rom is full of bloatware from samsung. I've read reports from other people saying that their camera software or galery or something else, don't remember exactly was uploading their photos to their cloud storage whenever they connected to internet. A lot of stuff can be happening in the background in the stock samsung rom because it's got a lot of stuff in it + the default settings alow synch/backup/downloading updates. Install the light custom rom from this forum, that has everything removed and see how it behaves, alternatively you can use other programs (mentioned one above) to see what's active in the memory of your device and find what's eating your battery.

Ok thanks. I will try silentlight tonight. By the way, I received updates of samsung link from playstore these past few hours and among the reason
for update was the battery drain. Also, I'm using an official S View flip cover from samsung. I was wondering whether there is some sort of sensor activated by this flipcase that keeps my mega from deepsleep.

Have a look here, one more idea for you - http://forum.xda-developers.com/showthread.php?p=44428107#post44428107
My battery drain problem appears to be related to "cell standby".
If I charge the phone to battery full, unplug, reboot, screen off, data off and leave it to stand by for a night. "Cell standby" alone takes up most battery usage and battery level drops by ~10%. I can constantly repeat that. I think more users are having a problem with radio.
Reference: http://forum.xda-developers.com/showthread.php?t=2335242
I am trying to disable fast dormancy to see if that helps slow down cell standby drain.
I have to come back @ my comment on the previous page, since today my phone went battery hungry too at night. left it in flight mode during the night as usual but instead of losing 1 or 2% it consumed 12%.
Very strange since the phone should be absolutly doing nothing at all when its locked and in flight mode.
It's not really a problem since im a fairly moderate to light user so i can do 2 days on 1 charge but still.
I also have a strange wake-up problem now, after using the phone a bit and when i press power to lock it, sometimes the screen lights up again after about 5 seconds and goes off again.
I feel worse than it actually is when I feel like robbed 10% of power everyday for no reason. Maybe I was too picky. I have not given up on this. Will continue to look for a solution.
same **** here, today is even worst, 8 hours of phone not doing anything. deep sleeping is at 92% according to BBS, and my battery dropped from 75% to 61%, wonder wat is happening with my phone. damn!
Try this
Sorry. Very bad know English. Solved the problem of the so-

Ok, as many users are reporting the brand new moto z and the variants, like droid, force and play are having extremely WiFi battery drain, sometimes number one or number two on the Battery stats; in my case it was number one or two, somedays even higher consumption than the STO.
This is what worked for me, my phone is the Moto Z XT1650-03:
Go to settings/backup and restore/Reset Network config and apply it. This will erase all your WiFi networks.
Restart your phone to apply changes.
After the rebooot you can set the WiFi again or leave till the end. So, here are the final steps to avoid battery drain.
Go to Settings/WiFi and touch the three dots (upper right corner)
Select "advanced settings"
Open Wi-Fi on during sleep and select "Never"
Open Wi-Fi frecuency and select "2.4GHz Only"
Exit Wi-Fi settings and return to the main screen of "Settings"
Go to Settings/Location
Open Location Mode and select "Device Only"
Touch the three dots upper right corner and enter, there is only one option.
Disable both options "Wi-Fi and bluetooth search".
After serveral tries this is what worked for me, even you can use "Smart lock" and all the apps that use location services, like maps, are working perfectly and in my battery stats the Wi-Fi disappear at all, not even the last.
Please, comment your battery stats and possible solutions.

A little more than 24h after following the procedure I'll have to say that did the trick:
The Wi-Fi wasn't turned off, but by the chart above, as soon as the phone went into deep sleep mode, the wifi was shut down (as expected when doze mode kicks in). The phone was fully charged 6am today and it's battery has been holding pretty well. It's almost the end of the day and it still got 89% of juice left, with over an hour of SOT and with 3 days battery readings, something I've never seen since I first turned on this phone. (it is in airplane mode not to save battery, but because my room has pretty bad reception, and as long as I practically receive NO phonecalls, there's no point keeping the reception on, it will only drain more battery over nothing)
I've seen a link around here in the forum explaining this wifi battery drainage is a Marshmallow algorithm error, since it's impossible the Wifi alone consumes more battery than the Screen, something considered impossible by the article. Here's the link: http://androiding.how/how-to-fix-wifi-battery-drain-on-marshmallow/
I don't know if this procedes, but my battery readings improved susbtantially since I followed your tips =)
Thanks a lot once again mate! :highfive:

I read the same, is a bug at the algorithm of MM, but, I felt that the WiFi was draining a lot more battery than supposed to do. Since I did this my battery was really improved and the WiFi is not more and issue. Glad it helped you my friend. Regards!

Two screen shots attached. Only 28 minutes SoT since removing from the charger 12ish hours ago.
I'm not sure if it worked or not. As you can see, despite my wifi being disabled the entire day, the wifi was active 100% of the time. HOWEVER wifi power usage doesn't even register on my battery usage screen. My biggest power hog is poor cell reception due to the concrete bunker I work in. My battery usage is much better than last week, and I'll easily get 2 days out of this charge.
Did it work for me? Maybe?
You seem to have a lot of wake locks. That probably doesn't help your battery along with the very poor signal.

I don't know why your Wi-Fi doesn't turn off. As you can see mine goes off sometimes. But as I can see it worked for you despite the poor signal (mine is poor too) and I get almost 4 SOT everyday. You can check with wakelock detector what is wakening your phone so bad, you don't need root anymore to use it.

Will try this for sure. I had tried something similar but turning the Wi-Fi on during sleep to "Never" resulted in me not getting any notifications (whatsapp, emails, etc) during sleep (cellular data is turned off). Do you guys still get notifications when the phone is in sleep?
Moto z droid wife
I did all that but is still not working
My wifi, Bluetooth and hotspot are disabled
Battery drains faster
I'm kind of bored with the phone
Any update to fix that...?
Does this fix work with Nougat? I don't seem to find the WiFi frequency option anymore.
I am only noticing battery drain when the WiFi is ON (even if I set it to never be ON when in sleep mode).
I also noticed the CPU only stays in deep sleep for 50% of the time, and 50% is running at 652MHz.
As soon as I turn WiFi off manually, CPU stays in deep sleep when screen off.
Thanks! This is a great one!
I have an LG G6 and a V30 on the Verizon network. On both, phone idle is using most of the battery. I've read several posts and searched the net without finding a solution.
I use a Samsung Gear S3 watch. Not sure if that could be the culprit.
When I Googled it, seemed like many others were also experiencing this problem. No one on this board is having this issue? Or has everyone figured out a solution? Thanks..
Why do you feel it is a problem? It doesn't matter unless your total battery life is not good to excellent.
Sounds like you just leave your phone Idle more than anything. I don't see a problem.
Sent from my LG-H932 using XDA Labs
check the battery usage ... find the offending app.
I am seeing the same: I don't use my phone very much, and not for gaming or video or anything very power consuming. So idle is by far the biggest battery drain on my V30 as well. The battery is still great on this phone, and it is quite frugal during use (as opposed to my beloved old Nexus 5, which was frugal when idle, but every touch of the screen would deplete the battery): I only charge the V30 every other night, and usually get 4-5 hours SOT on a full charge.
Battery stats attached. I have disabled most Google features (location reporting, always listen etc) but as you can see, Android Kernel and Android System remain by far the biggest app suckers. Lots of LG services buried in those. Some day I'll try and figure out which ones are the main culprits.

Either this is a bug from software or this is the way the phone display itself..
As long as it doesn't effect the battery usage, it's not a problem imo
The high idle drain is real, at least on my phone. It is NOT merely an error in how usage is displayed. If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.
This is fact, not opinion. Of course it could be unique to my phone and the OP's, although a few other threads mention high idle drain as well.
As I wrote in my last post, the phone has a good battery AND a frugal display, which means it's not a problem for most. Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.

I'm actually seeing the opposite on my phone. Idle battery drain is minimal, but I feel like it drains a bit faster than others while in use. I did disable a lot of carrier/LG bloat I'm sure it's helped with idle battery usage to a degree.

Thank you for sharing this. Good to hear that your idle drain is low after disabling LG/carrier bloat. Makes me hope that if I take the time to go through it on mine, I may see improvement. So far I uninstalled a couple of LG apps through the Settings/Apps menu, that's all. I've meant to do more with ADB, just haven't had the time yet. Your post is encouraging in this regard.
But puzzling that you find active drain so high. My old Nexus 5 was like you describe: Very low idle drain (lean custom ROM and not many Google apps installed), but drained fast whenever I used it. As described, the V30 surprised me by doing the opposite. Hmmm....

Well it's not excessive relative to other phones I've used, just seems higher than other people based on their battery usage screens posted.

Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.
@mankind_18: I am glad to hear that this is not a problem for you.

I think it's kind a normal to find idle taking up most battery if you're not using the device (i mean less), because when i compare it to a9 pro, it's the same actually.. when i use it often, screen will take the most battery percentage.. but if i use it less, device idle will be the most at the top..

The high idle drain is real, at least on my phone. It is NOT merely an error in how usage is displayed. If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.

If the phone is flat in 3 days, then your idle drain rate is 1.25%/h. That's elevated.
It should be possible to improve depending on what the causes are. Could be apps, could be apps you need and then there is the network.
As a simple test, charge up your phone before you go to bed. Then leave it there, untouched with AOD off.
In the morning, settings - battery - battery usage - estimated time remaining <-- how much is that ?
Your battery will have to drop to at least 98% before that info is available which in your case could be sooner than morning maybe in a couple of hours

True. After two days you've lost half the battery. Ideally it should be less than that.

Do you have access to a PC with adb installed ?

Thank you for the response. That was posted over a month ago, and I finally did get around to disabling (or rather, uninstalling with ADB) a bunch of LG apps and services. Also some T-Mobile apps after switching to AT&T MVNO. That helped a lot, and I am now down to approx 0.5%/hour idle drain. That's overnight, mind you, and I still find it somewhat high considering AOD, Location, Bluetooth, NFC are all off, and the phone is completely still for 8-9 hours.
But I can now generally recharge only every three days, and still get 6-7 hours SOT. I guess that is great for any phone. Sometimes and I have to use Battery Saver to make it that far. It helps a lot to reduce battery drain, both during idle and use, and has no noticeable effect on usability.
Also on the positive side, I haven't had any of the lag issues mentioned by others in various threads after disabling apps. In fact, it is even smoother than before disabling them. I did go a bit too far, as I lost the ability to Google Cast the screen -- strangely, as I didn't touch Google apps or services. Also, I lost LG SmartSettings, which I didn't actually use, but didn't mean to lose either. I kept the SmartSetting app, but apparently one of the LG task related apps I disabled caused it to disappear from Settings. No other issues or functionality losses -- except the ones I wanted to lose.
So I am OK now -- though I still think idle drain is higher on this phone than it should be, even after disabling LG's duplicate and redundant services and turning off known battery draining features (AOD, Location etc).
Edit: Thanks again for your response and offer to help. Re-reading my post, I don't think I fully acknowledged that.

By adb i was referring to granting a one time permission to the better battery stats app. Will be a good next step if you've not used it yet since you've done a cleanup already.
The dump file will reveal what your phone is up to when you set it down and whether further improvements can be had if feasible.

How did you measure that rate ? wonder if its possible to reduce it further. Up to you

6-7h/SOT is normal for the v30, on wifi or bands 12 & 20 with heavy use.

If you're interested in exploring further with BBS, let me know. It has a strict procedure to follow which i can walk you through

I did grant usage stats permission to GSAM. Otherwise it wouldn't have shown the details in those screenshots.

GSAM can show stats for various time periods, including custom ones. I generally check it in the morning after it's been lying on my desk or nightstand overnight for 8-9 hours. That's the ultimate Deep Sleep condition.
MY cell radio uses a bit more after switching to AT&T and returning the signal booster that T-Mobile provided me. The booster didn't improve T-Mo weak's reception in my apartment, but it DID provide a stronger signal to the phone, so it doesn't have to work so hard to maintain it.

I'll take you up on that. I haven't used BBS in years (different phone) so not up-to-date on it at all. I'll follow your procedure, just tell me what to do.
Thanks again. Much appreciate your help!
Edit: I downloaded and installed BBS 2.2.2.0. Holy crab, I can't believe that thread is now 3300+ pages!

Good, this will allow you to compare both tools and see which one is more useful.
Now you need to give BBS the permission in ADB as shown here
adb shell
pm grant com.asksven.betterbatterystats_xdaedition android.permission.BATTERY_STATS/
That's it. Switch off Developer options.
Then go into BBS-Settings-Advanced- (scroll to the bottom and click System App) and verify it says BATTERY_STATS granted. Cannot proceed further otherwise.
If ok, back out of advanced and tap 'Watchdog' then enable
Next, try a dry run. AOD off. Let the cell be on since that's how you use it and wifi.
What battery level is when you start the idle test matters. Can be anywhere between 50 to 95 but not over or under. More consistent data between those two points.
Let it rest for an hour. Do not touch it during this time. if the phone rings and you answer it then your log is going to get polluted with irrelevant info. It's useless, have to redo the idle test. The not touching it matters a lot.
When time is up, in the app under summary there are a couple of dropdown menus. Select 'Screen Off' instead of 'Boot' for the left and the menu next to it, select 'Screen On' instead of Current. Telling it to print data only during the time screen last switched off and turned back on. Very handy. As you can use your phone before the test and when ready to do the test it doesn't matter where you start within the limits mentioned. Screen off to screen on, That's what watchdog does.
After that, Look for the share button at top and select Dumpfile then Save. The txt file will be saved in emulated/0 so in LG's file manager, Internal storage, scroll down, it should be there by default. file name betterbatterystats- date-time.txt
Post that txt file as an attachment in your next post. Hopefully, on the V30, BBS will record under the sections, partial wakelocks, alarms, network which are required to understand where wakes are coming from. If this part is successful then you can go on to do a real idle test.
There are three key points here,
- idle test done when battery between 50 - 95
- your screen on during the idle test cannot exceed 1 minute. No touching
- getting the correct start and end points meaning you selected screen off to screen on to record in the dump.
Get this down right and you will be ready to do a real idle, test. There is one extra condition now. Test cannot be less than six hours. Can certainly be longer but not less than 6h. This is where the no touch rule starts to grate but that is the minimum time required for any wake locks to make themselves known. Getting the procedure right means you don't waste runs. And you will be doing several as you hone things
A bit rigourous but this is what the creator of BBS and the guys in that 3k+ thread insist you do to get the most out of BBS. They won't look at your dump file otherwise. Redo it they will say

Thank you. I'd already granted it permissions (BATTERY_STATS and DUMP). But I cannot install it as System app, since I am not rooted -- which it promptly tells me if I try. I was looking for somewhere to confirm the permission, but didn't find it.
Anyways, I started the Watchdog. I'll be charging it overnight, then do the dry run tomorrow after the battery has dropped below 95%.
Thanks again. This will be interesting!

Ah, i wasn't clear, install as a system app isn't required, that screen is just to check if the permissions took.
A popup appears saying root is required and disappears after a second or two, if you see the word 'granted' then you're good to go. Fingers crossed the right sections get data
