Extreme battery drain?? 6.0.1 - Nexus 6 Q&A, Help & Troubleshooting

Has anyone else run into this after 6.0.1 update. It really didn't hit me until last night when I decided to test it. Unplugged my phone at 80% and went to sleep only to wake up to it dropping almost 50%!!!!!....not normal. It looks like something is just not right with everything after the update because after checking everything, nothing seems to fit. And before you say it was my wifi, I just changed that, this happened even if wifi was off. But I can say doze is definitely not working and no app seemed to go "rouge" with wakelocks when trying to check. Going to downgrade back to a previous build of 6.0, but hopefully someone else can chime in. Only found a few articles of people reporting the same thing but no one is actually posting possible solutions, just bashing a legitimate concern. Hopefully I don't run into that here.....

Try a factory rest, fixes 99% of issues.

turn off wifi scannning, in you location settings. notice that your wifi us in the whole time? and i bet that you arent even using wifi.. well, turn it off.

Only out of place thing I see is that your screen was on at some points but the phone wasn't saying it was awake. That leads me to believe there's a kernel wakelock issue because I had the same thing but on 5.1. The issue turned out for me to be a wakelock called bluesleep which is related to bluetooth and it came about from an app called gasbuddy which silently updated to provide support for bluetooth "beacons" at gas stations to give you deals or some crap like that. If you're rooted you can install BetterBatteryStats to test for kernel wakelocks, you can test for bluesleep wakelock by just turning off bluetooth and seeing if the drain/weird screen-on not awake thing happens, and long press power off to start the phone in safe mode to narrow down whether its a system issue or installed app issue and if rooted use an app freezer like Titanium Backup to freeze your installed apps a few at a time to narrow down what app(s) are causing it(so you don't have to uninstall/reinstall trial and error).

Wow thanks for that, I actually use GasBuddy, wish you were here before the factory reset I did, but everything seemed to go back to normal after I did the reset but I wanted to actually try to find out specifics. I haven't rooted just because I use Android pay (I know system less root us out there) but I'll try to keep an eye out for that stuff if it happens again.

Lol, it's all good, but yea, that wasn't the issue, doing now with wifi always on and battery drain is normal and doze is working properly, so probably a bad flash and factory reset fixed it, although I really wish there are ways around that

Disabling FastDormancy?

How do you do it on Atrix HD?
I ask because FastDormancy is killing me!

This is for a phone that is not at all used! 4% an hour for a phone that isn't used is a lot, especially given FastDormancy is keeping the phone awake for 1 hour 7 minutes out of 2 hours 57 minutes, a whopping 38%!
Clearly my carrier doesn't support FastDormancy or it wouldn't take so long to send the disconnect messages!
The worrying part is that I have even changed the radio to GSM Auto (PRL) in an attempt to reduce battery life as the phone constantly tries to get the best 3G signal possible which is anyway sketchy in my house.
Help appreciated. Thanks.

If you're rooted, get Titanium backup pro and freeze "orientation notifier", "modem fast dormancy...", and "modemstatservice". Under battery, these were labelled as "wakelock" and used about 25% of my battery.

Do all three need to be disabled or freezing just "modem fastdormancy service" is enough? What does "orientation notifier" do anyway? I thought it was to do with screen orientation.
Those three fall under wakelocks, hence all three being disabled did the trick for me!

Well I have only disabled "modem fastdormancy" and it has done the trick for me. Why disable more, especially when you don't know what those two do!
What exactly do you mean by "fall under wakelocks"? Using which app? BetterBatteryStats only showed me modemfastdormancyservice doing a partial wakelock and keeping the phone awake.

Under Settings>Battery..........you know, without some fancy app
I disabled them because they ALL caused wakelock. You can do what you want, but like you said "modemfastdormancyservice doing a partial wakelock" I didn't risk it with the others. Disabled all of them and not a single problem

Okay, so far I have never seen anything like "wakelock" being displayed in Settings>Battery.
And, before you disabled, did you find out what those other two did? fastdormancyservice is self-explanatory but google search doesn't bring up much in terms of results for the other two. Why take a risk? But you say everything works fine? LTE, HSPA+, HSPA, EDGE, etc. and the networks seemlessly switch when you go to an area with weak LTE/3G signal?

I'm using it unlocked on T-Mobile....get HSPA+ speeds fine. 10mbps down and 2 up, goes to E, wifi. You can always try it and defrost it if it cause you problems. It's not like we're telling you to delete something, so I'm not understanding this RISK you speak of.......

Risk as in if it suddenly doesn't boot anymore, etc. Has happened once for me so I'm very, very cautious. Especially since I do not have a recovery installed to create a nandroid backup. Anyway, I haven't seen the "wakelock" option showing up on my settings>battery screen till now. If it does, maybe I will try freezing the other two you have mentioned as well.
At least as far as I can tell, freezing the fastdormancyservice alone seems to let the phone sleep without any problems and the other two services you have mentioned certainly aren't running. Maybe the fastdormancyservice is required for the other two to work and with this frozen, they shut down as well I don't know.
also can try going into your build.prop and changing this line:
ro.mot.ds.fastdormancy.disable=false
to
ro.mot.ds.fastdormancy.disable=true

Thank you. Found it. There is also this line:

What does that parameter refer to? Should that be changed as well? My instinct says it should left as false since they did not want FD to be active during a call but I wanted to confirm just in case.

P.S.: Unfortunately, it does not seem to work. I have changed that value to true, rebooted and the "FastDormancy Monitor Service" is still listed in the list of running apps.

might still be running in background but not active. I would leave it as true and freeze the modem in TiBa

[Q] Has anyone figured out the "mobile radio active" bug?

I know we've had some discussions on the "mobile radio active" found on some apps causing battery drain. Has anyone seen a fix for this yet? It is still driving me crazy.
huh? mobile radio active? whats that, a wakelock?

I was wondering why my battery life was horrible since updating.
Sent from my Nexus 6 using XDA Premium HD app
I had this issue on 5.0, 5.01, and now 5.1. Been with it the whole time. I've tried different radios and clean flashes and wipes. Nothing is getting rid of it. When you search google there are some people with the same issue but nothing major which leads me to believe some things wrong with my phone and/or there's something causing this and it isn't normal.
I've never seen this

One issue I have is with the Facebook app and I believe that is causing a lot of my battery drain when not on WiFi. In a recent update Facebook removed the option to not automatically update news feed. Now I believe it refreshes very often causing massive drain.

This is NOT an Android bug. This is *possibly* a BAD SOFTWARE issue, or PERFECTLY NORMAL.
Every application that transfers ANYTHING over the network, will cause mobile data activity, which REQUIRES activity on the radio, and DOES draw battery power.
If an application transfers too much, or too often, or too slow, or anything else that will cause the radio to activate frequently or for longer periods of time, then you will see this mobile radio active timer increase.
And the MORE applications you have doing this, again, the more battery it will suck down.
Edit: Your example of pushbullet.... in order for that program to work, it needs to maintain persistent connections between each device you are using that program on, and the vendor's server. In order to maintain a persistent connection, packets have to be transferred across the route on a timed basis, where the time is less than the timeout on all of the routers along the route.
Conclusion: everything is working correctly as intended.

really? thats normal? then how come noone else is really seeing this "issue" other people say they dont have this so how would it be "normal" ? not saying it isnt because I dont know enough to know, but i would imagine if it was normal behavior then it would be on everyone's phone.
No way it's normal. I use chrome beta and it clocked over 3 hours of Mobile Radio Active today. I still got great battery life, but when Chrome Beta takes 20% and your screen takes 10%, something is wrong. It's not continuously updating as someone above suggested. It's a bug. The mobile radio is being kept active for no reason by seemingly random apps. I really hope someone figures out how to fix this.
Any update on this?
I've tried 5.1 e, l and now I builds and they're all doing the same thing.
I've tried chroma ROM as well, along with stock, lean, Franco and code blue kernels.
I've never been able to shake this problem.
Anyone know what its about?

No one has even confirmed it is a problem yet. Unlikely anyone is working on it.
At first, I was thinking this was app related, but after looking at all my background and running apps, it seems they all have this "bug". However, mine don't seem to be running that as long, which in turn isn't showing a big battery drain. Hence the fact that I never noticed it.
I am guessing that it is some wakelock that is set by the app, but all apps that connect to the internet are using it. However, I looked on my flo which is running BrokenOs 5.0.1 and it doesn't have this mobile radio active process. I will be updating it to BrokenOs 5.1.0 here in a bit to see if it appears. If not, then we can limit it to just the shamu. If that is the case, then we just need to locate it, probably in the kernel, and decide what to do with it...
I'll follow up with my findings later...
I hope there is a solution!
For me it is the problem with Android 5 or the nexus 6. although i dont think it is a problem with the nexus 6. After my recognition are different models (nexus 4, 5, some Samsung devices, moto x...) affected after updating to lollipop.
I have also test different (stock-)roms/ different kernels/ disabled some services/ tested different radios/ factory resets and freezed some system- or deinstalled all 3rd Party apps/ changed the messenger...
No problem in wlan but with 4g/3g is the value of mobile radio active to high that some "apps" (gpservices, android os, hangouts, telegram, sometimes chrome) now are on top of the battery stats. With bbs or wld i cant find the reason.

It *IS* on everyones phone.
Nobody is 'seeing' this, because there is nothing *TO* see. There is nothing *TO* see, because it is PERFECTLY NORMAL.
You can't seriously expect mobile data transfer to be done free of battery consumption, can you? It takes electricity to produce the electrical impulses that generate the radio waves that carry data to the remote cell tower. It takes electricity to run the radio processor cpu to receive and interpret the electrical impulses in the receiving antenna that are generated by the radio waves sent by the remote cell tower.

There is nothing to see when some apps on top of the battery stats (with 3g/4g) because of the high mobile radio active? Why are this value not so high on other devices with KitKat and then higher with lollipop?
Being connected to wifi for a period of time may help reveal more info.
Also, try using a whitelist firewall to only allow apps that you need to allow data. Or even block all traffic for a while and see what happens.
You could even block traffic on only cellular, and let only wifi pass traffic.
Another thing to verify would be whether airplane mode (wifi could be on) indeed causes the issue to completely go away as one would expect.

Wifi always on, even when off in every setting

heres a silly qiestion.. how many of you arel seeing wifi always on even though you have scanning always enabled turned off in wifi settings? i noticed this last night, and thought that its unusual. i did get mine to finally turn off, but i had to delete nfc from my phone.
btw, you can check in the battery stats page. just press on the graph, and it takes you to another page.

I can also confirm this. Even with everything turned off, I still get notifications of available WiFi networks. ???
I get it. Been on the road all day with no access to WiFi and WiFi is off as well as the option to let google scan for WiFi. I don't notice any battery drain. Looks like a bug

if you have root.. i used root explorer, but any root file explorer should work. you go to /system/app/, then find the nfc app, delete it, then reboot. if you dont reboot, its not quite deleted yet. it is, but files are for it are still there.

real battery drain i didnt notice either
If WiFi is off in settings and it still shows I think its a bug, because if you check it with gsam it shows it being off. A reboot with WiFi off when you reboot will fix it. I had the same thing on my m8 and now with this device also. Its a lollipop bug.

Did you notice any actual benefit from doing this, ie increased battery, reduced power consumption etc
Down side is obviously lack of NFC although I don't actually use that so that's no impact

i only "fixed" it right before starting this thread. i dont ever use nfc, ok, once in 6 years, so its no issue here either. i actually normally delete it, but let it slide after 5.1.

On thinking about it.
I always leave my WiFi on which would most likely explain this pattern, unless I'm misunderstanding how this should actually work.
For example, I leave my house, the device automatically switches from active WiFi and jumps on to mobile data, but I suppose WiFi is still on in the background, I have scanning setting set to off. But the WiFi must be constantly scanning for an active connection with valid Internet access, as whenever i pass an active WiFi zone that I'm permissioned to access the device will jump onto it and then when I leave it's signal cover it falls back to mobile data.
This would obviously explain the constant pattern.
If I manually stop WiFi then the bar disappears completely from battery statistics.
So no mystery after all or I have got this wrong.
Slightly confused as to the significance of the nfc removal now unless I've completely misunderstood your initial point.

But the WiFi must be constantly scanning for an active connection with valid Internet access, as whenever i pass an active WiFi zone that I'm permissioned to access the device will jump onto it and then when I leave it's signal cover it falls back to mobile data.
This would obviously explain the constant pattern.
If I manually stop WiFi then the bar disappears completely from battery statistics.
So no mystery after all or I have got this wrong.
Slightly confused as to the significance of the nfc removal now unless I've completely misunderstood your initial point.

i dont know how the nfc is connected either. but i do know, if all else fails, it works
I know that whenever I flash a new ROM, and get it booted up and then turn off WiFi that according to batt stats its still on. If you reboot it removes the signature from stats and it will show as it should.
I don't think this is a bug. It only looks like WiFi is always on in the battery history when you have your location services set to maximum or medium accuracy. So even if you switch WiFi off completely in WiFi settings the device will still use WiFi to pinpoint its location. If you select the lowest location accuracy setting, you should see that WiFi bar below the battery graph stop. At least that's how it used to work on my Nexus 5. I stopped worrying about it after that.

Well if your running high accuracy all the time with wifi on then that makes sense but unless I'm mistaken that's not the issue. I can reproduce the false WiFi problem every ROM flash on two different devices running lollipop.

Fair enough. Like i said I only recall that by turning down location accuracy and turning off wifi on my N5 the device finally stopped reporting WiFi usage. On my N6 I have WiFi and high accuracy location on all the time so didn't realise there was a false reporting issue til seeing this thread. Hope it gets fixed in a future update I guess.

i only "fixed" it right before starting this thread. i dont ever use nfc, ok, once in 6 years, so its no issue here either. i actually normally delete it, but let it slide after 5.1.

I'm seeing the same dang thing, my first thoughts were the WiFi only when plugged in or never, and then Google Location Services (making it device only), never thought NFC could be the culprit. I don't use it either, but I'd hate to think this feature that Google has been trying to push is putting WiFi on all the time, irrespective of if it's draining the battery.
I'm going to move the file from system and see how it goes.
Wouldn't freezing it yield the same outcome though? If yes, it'd be a slightly easier step for some.

Unstopabble Battery drain when wifi on. Will Paypal $20 for solution.

I have a S5 plus G901f. I have had the phone for 5 months now, and to cut a lot story short, since it was out of the box brand new on stock everything, going through kitkat, lollipop, marshmellow, all stock updates, and now bunch of custom roms and custom kernels, ALL to try stop this wifi battery drain, NOTHING has made a difference. Nothing has worked.
Whenever WIfi is on, the battery will drain about 1% every few minutes, no matter what. With the Wifi OFF, the battery graph will be a horizontal line and the phone will last over a week.
Does anyone have Any idea how to fix this issue. My S6 S3, etc do not do this. They have perfect standby with wifi on.
If anyone offers a solution that works, I give you my word I will paypal $20 to you. Its easily worth that.
It looks a little something like this. The flat parts are with Wifi OFF.
GSAM battery stats just reports it as Android Kernel, Android reports it at Android OS.
Maybe try checking with wakelock detector free in my case it's better than gsam
Is that a custom rom or stock?
If custom the android system will drain less after a week.
You might try to boot up in safemode and see if the system ui drains battery.
If not you can do a Factory Reset and see if it worked.
Download network connections app and sd maid app from playstore.
Run first network connections, see if you find a app that still there and has network traffic. Unatural if you find an app that sucks much traffic.
Use sd maid and go to app control. There you can see which app is active and turn all third party apps off, also the autostart of the receiver.
After that is it always draining?
Of course you can use the system and app cleaner of sd maid if you like.

Read first post. Have done more than factory reset. Both on Custom and stock roms. It doesnt matter what rom.

Will try all those things, but have gone through with titanium and blasted everything in the past with no change to the problem. As I said it only happens when WIFI is on, if mobile data is on but wifi is off, there is no problem. It sucks but I think its a hardware issue...
Will try all the suggestions.
Just for information, OP. Thanks for offering 20$, but you could try and resolve the issue yourself by installing BetterBatteryStats, and checking out what' exactly in the "android os" is causing the wakelock
Also I'd recommend flashing a completly new system with Odin, in case it's a virus - one of the guys on my job had one (probably still has )
I don't want the money but if you are on marshmallow turn off bluetooth and wifi scanning it should help.
It's not impossible that you could have a hardware defect . I'd try contacting a Samsung service center but it looks like you won't be covered by the warranty since you probably tripped Knox when you installed a custom rom.
If you have flashed 100% stock, and factory reset, flashed custom and factory reset, and back to stock and factory reset, and it is still doing it, it sounds fairly likely it is not a software/firmware issue, but hardware
RMA
If you have the HuffPost app, uninstall it for some time, it is my only news app installing itself in autostart/as background service, despite the all offering push notifications, which i have disabled for all these apps. Huffpost can go amok, causing much drain. But with root and Wakelock Detector you may spot your culprit.

Could be a faulty battery,did you try using a different one?
It's very unlikely that a "faulty" battery would die with the small drain of WiFi and not turn off immediately when the screen turns on.
I regularly go to a place where the wifi signal strength is weak. My battery drains faster, even during the standby, while being there.
Wifi power save mode
1. Go to your phone dialer
2. Dial *#0011#
3. When you see the "ServiceMode" screen, press the left menu button
4. Select "WiFi"
5. See that "Wifi Power Save Mode" - well turn it "on"
6. Exit this menu
Hope it works......if its a harware problem it should work but put down yours wifi performance.
From Ajay have a great day....
Boot your phone into safe mode and see if the problem keeps happening and if not get a zero lemon battery case

The $20 dollars is there because it is such a persistent problem it seems like a miracle if it were to be fixed. Its a problem that I do not know the cause of so Id be laughing if it was fixed for $20.
Ive tried most of the suggestions. The culprit seems to be wlan_wow_wakelock. Have no idea how that helps?

Tried close range, different wifi. Different wifi routers does tend to make a difference to how fast it drains but always a strong trend down. In my home the phone is only metres away from the router, full signal.

The only option I see in there is Ping test. No wifi power save mode.
This is not a common bug, at least not with the common G900F. What does the "1" stand for?
It could be a mismatch between rom and baseband/modem. This shouldn't happen on unrooted phones during updates(OTA or Kies).
With TWRP, you should be able to flash the correct modem firmware, if there is said mismatch, otherwise the unbricking procedure with Kies or Odin should help. A total factory reset/unbricking is the ultimate solution anyway. A certain app may also be the culprit, so uninstalling these one by one may provide a solution within a certain time, starting with battery saving apps and the like.
Hardware damage just preventing power save seems unlikely.

Read the thread please. No a total factory reset is not the ultimate solution, its not any kind of solution because the reason I started using custom roms is to try fix the problem with the phone when it was 100% stock. The correct firmware was on the phone when new, and it still did it, and it still has the right sofware now afaik as I'm only installing g901f roms.
G901f is the Galaxy S5 Plus. Its basically like a note 4 inside fitted into the body of an S5
Just so you guys know the above pics of the battery graph show with wifi on, the battery drain, and with wifi off, almost no battery drain and on again.

Funnily enough if I leave the screen on the wifi almost drains no power, and its the drain same as leaving screen off lol.
This is with over 1h of on screen time with wifi on.
Its the same as leaving the phone on standby with wifi on lol. Wifi stops being crazy and normal drain occurs.
Thats why Im saying its worth $20 for a fix. Because its BS. I think the only fix is in the form on a kernel where someone understands what the problem is.

Question Bluetooth Battery Drain

Hey guys. Since the April update I've noticed I'm getting a fair bit of Bluetooth Battery drain on my Ultra. Only thing I have connected all the time is my Huawei GT2 Pro watch, but this has always been the case and never had the issue.

Just a small snap shot from this morning.
Never used to see any Bluetooth use here really. Have rebooted both devices but seems to be getting worse.
Any ideas ?
Clear system cache.
Do a network reset... see if that helps.

Do a Google search if you don't know how for that make/model.
Network reset is generally found in setting under connectivity at least on Samsung's.

I don't think Karma Firewall's logging feature works in Android 10 or 11.
That would allow you to see what is accessing the internet and how often. Might give you a clue to what app is responsible.
It may be an app connected with the watch that's gone wild. Google Play Services is a known troublemaker and battery hog.
Man it's somehow getting worse ...
Why is app usage so high?
It's not broke down by app. Wonderful.
More Android 10/11 security?
Try disabling Google Play Services... just a hunch.
If that doesn't work...
Go to Developer options>running processes/cache processes after a reboot and see if you can spot it.

That is a mess. Ditch the trash social apps especially FB and insta****. Health is doing what? Is DeX just hanging out too?
All that message stuff?
G Board?
Which of these has bluetooth permissions?
Time to take out the trash... if you can bare to part with it. It all adds up.
The Adroid system looks high too.
Disable all power management after you take out the trash. Power management can cause erratic behavior and battery drain.
This what my 10+ battery profile looks like. I was using bt for a couple hours but it's bare bones.
The bells and whistles are power sucking and annoying.

Have you tried turning off nearby device scanning (under connections) and Bluetooth scanning (under improve accuracy in location)?
Also are you able to see if anything is draining your watch faster than it was before?

That should be ok then.
Google apks are notorious troublemakers though. Even Gmail I keep on a short leash.
Maybe the data in Health got corrupted, try clearing data or reloading it.
Don't forget all the Google apps and their many dependencies. One might be polling constantly and going unanswered*.
Tracking something like that down on a unrooted Android 10 or 11 platform is a bloody nightmare.
*I simply disabled Google Play Services expect when I need it because this.

If you disconnect the watch does the drain stop? Does the drain continue if you connect a different device? Might be easier to try resetting the watch before the phone?

It's been ok today. Only at 2% for the day

You can disable GplayS in settings to see what happens. Mine is disabled right now.
You can also download Karma Firewall then firewall block GplayS, Google backup Transport and Android Services if those latter two aren't used by you. See if this helps.
