Recent battery drain after upgrade to LMY48M - Nexus 6 Q&A, Help & Troubleshooting

Hi
I recently upgraded to LMY48M (flashed it) on my Nexus and I've been getting this battey drain issue where the battery is draining really quickly, almost half the original life.
I tried googling this issue and learned that this in fact is an issue almost everyone is facing with LMY48M. Is there any fix for this?

I am on that build and not having any issues. You might try booting into recovery and clear cache/dalvik.

Sadly this fixed nothing. Battery still drains after clearing cache.
I know for a fact this isn't a hardware problem though because it works fine on LMY48i

I had same issue and did a factory reset and its fixed it.

Radio active bug...,I flashed mine back to 5.1 and everythings fine again.

Have you tried to figure out what's causing the battery drain? There are plenty of tools available to help you determine what's draining your battery. It could be any number of things and you've given us nothing that will allow others to help you.

I don't know a lot about this I'm also new to the forums and don't know how stuff works and what I need to 'provide' in order for you to help me. Kindly name 'those number of applications' that can help me?
OT: I cleared the cache partition and it fixed the problem minorly but still didn't make it perfect like it used to be.
Also factory reset which again; might've helped but only a bit because the battery although is better than it used to be, but still isn't running perfect like its suppose to.

Nothing to figure out there. Radio stays active, even when youre in wifi. I only flashed 5.1 and it went away, just as I wrote in my comment.

"Radio active" is meaningless, since the radio is on a separate chip from the CPU.
Go into your battery screen, tap on the graph, check the WIFI activity bar. I've occasionally seen it where if you turn on your wifi AT ALL, and then turn it off, it keeps on being "on" until you reboot.
You can also go into your wifi advanced settings and turn OFF "Scanning always available". Not sure if that fixes the problem of it staying on or not, but doing that also is likely to help with wifi power consumption.

According to BBS, GSAM, and the native battery monitor, my radio isn't on all the time using LMY48M.

Residue from old kernel, possible ?

Hi all.
I've been experiencing a weird issue.
I've been a RocketROM user for a while now, and never had any battery issues.
Yesterday i decided to try the Abyss kernel. As soon as i flushed it (wiping caches before) i started experiencing high battery drain.
BetterBatteryStats showed WLAN_RX_WAKE as the main culprit while the built in battery stats showed Android OS as the culprit.
So I decided to roll back to the backup i've done prior to installing Abyss (FM Kernel - Rocket V11) but noticed that even after restoring i am experiencing the same issue.
I have since tried clean wipe and at least 3 different restore points (all with FM kernel), but in each case i keep experiencing high battery drain and the phone can't get to deep sleep, all the while the only thing that BBS shows is a kernel wakelock WLAN_RX_WAKE and android OS as the highest "spender".
I suspect that Abyss left some file/residue that keeps causing the issue even after i removed it/clean wiped.
Is that possible ?
I know there's a kernel cleaning script for SGII.. never heard a mention of it for the note.
Would appreciate any pointer/suggestion at this point, as i am quite lost.

+1. Exactly the same issue here.
I'm having the same problem, but on my new Skyrocket SGS2. Leaving wifi on drains my battery due to these wakelocks. Tried new roms and kernels, but it still plagues me.

Is your wifi on a Windows 7 network? I fixed my problem by cleaning up some things that were multi-casting from my Win7 desktops and keeping the phone active continually. Check Entropy512's known battery drainers thread in the i777 forums for some stuff I posted (and a lot of other good ideas to track it down).
Yeah i saw that and turned off the WMP network service and others, but after doing a Shark dump i don't think they were responsible.
I reflashed my phone to bone stock and monitored my network packets. 98.4% of the packets recorded are ARP protocol packets. My FIOS router and my computer asking "Who has 192.168.1.2? Tell 192.168.1.1" etc like that. Pretty much every second. During that time my phone was i think 25% in wakelock from wlan_wake and wlan_rx_wake.
It seems to only be polling and asking to find computers that aren't there any more. I turned my PC off and ran another test, and the router blasted my phone with "Who has 192.168.1.9" which was my PC's address. And blasted it so much that time it kept me 50% wakelocked.
Not sure how to stop these but it seems like these could be the cause... Or are they part of every network like that and my phone should be ignoring them? I'm gonna post my data in that Known battery issues thread later too.
I saw exactly the same behavior on my wndr3700 router. It keeps sending Arp requests every second or so. I too wasn't able to find out whether this is normal or not. seeing it happen on a completely different router suggests its normal but a confirmation from someone who knows would help.

Best solution imo is to flash a stock rom with Odin. Let it boot, and wipe the phone with *2767*3855# to original factory settings.
Than you`ll start clean again.

I'm still getting the ARP requests, but they aren't stopping the phone from sleeping and my battery life is excellent now. Cutting down the ones with "destination port: wcbackup" is what "fixed" mine. Try following this: http://www.corrupteddatarecovery.com/Port/8912udp-Port-Type-wcbackup-wcbackup.asp
and see if you can shut off the processes that are the worst offenders.
Thanks a lot for the confirmation. Could you say which rom and kernel are you using?

Sorry, missed the question - I'm using UnNamed 2.2.1, with Entropy512's 1/30/2012 kernel. At the time you asked, I was running the same ROM, but the 1/2 kernel. And the 1/30 kernel has cut my battery drain in half! Hope that helps.

5.1.1 Battery Drain

Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?
Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.
I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.
There is something wrong with your phone or app. I have about 100 apps. No problem here.
This is the international version of the phone

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).
How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.
Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.
Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.
Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.
I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.
Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.
So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.
I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.
I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.

Unusual battery drain

Hi,
I know there are many topics on the subject but I didn't find any solution to my problem.
So, since a couple weeks, about when I moved from Europe to the US, my phone drains significantly more battery than before. This has apparently nothing to do with screen brightness, wifi or cell data, since it occurs even in airplane mode during the night. I used to lose about 1-2% during a night, but now it's at least 15%.
You can find a couple screenshots from BetterBatteryStats there (sorry for broken link, it does not work otherwise): n.ethz.ch/~bauera/uploads/Screenshots/
So as I noticed, there are a couple wakelocks but nothing that could explain this large drain. Any idea what could be the reason and how to fix it?
FYI I am using the stock rom 23.4.A.1.232 with Android 5.1.1. Phone model is D5803. The OS was rooted directly when I got the phone in October 2015 and as I said, I did not have any battery problems until recently.
Thanks for your help!
Alex
that's the lollipop battery drain bug on mobile radio, marshmallow should have fix this
Thank you for your reply. However are you sure of that? The bug you are mentioning is apparently linked with mobile data, which I haven't even turned on since a couple reboots at least. Moreover, the battery stats for the night (from the built-in battery menu) show that the mobile network was fully off during that time (airplane mode).

BBS - Better Battery Stats is your freind. There's also lots of tips in the thread on how to limit most of the common wakelocks.
There are several services in the new Play Services that are keeping your phone awake. With the introduction of wearable bluetooth there are new fitness services that are looking for your wearable devices constantly, disable them and your battery gets better. Obviously if you use fitness bands/trackers then this fix is not for you.
If you have a rooted phone download Disableservice from the playstore, it's a lot easier to use than Xprivacy and you don't need to install Xposed.
Once it's installed, open the system tab, open Google Play Services, then untick (disable) the following:
ConfigFetchService
FitnessSyncAdapterService
GoogleLocationManagerService
GoogleLocationService
NetworkLocationService
ProximitySettingInjectorService
UserPresenceService
WearableControlService
WearableService
WearableSyncService
then reboot your phone.
Disabling these from running should have no impact on your phone, it doesn't for me, and will give you 10-15% more battery life.

Solved Battery drain for Me
I was also suffering from the same battery drain issue, but after doing a lot of research on this forum, few tricks mentioned here worked for me.
It had been 6 days I bought the phone, so was very disappointed by battery life, did upgrade from PC to Lollipop, but still the problem persisted and even worse. So I decided to go back to Kitkat and followed steps here: http://forum.xda-developers.com/z3-c...d5833-t2906706
After downgrade the battery got somewhat better not satisfactory, so I followed the trick of complete drain upto 0% and charge to 100% (switchded off) after reading posts: http://forum.xda-developers.com/z3-c...5#post59797105 by Sydr08 #182
and cache clearing trick after 0% to 100% charge http://forum.xda-developers.com/z3-c...harge-t3207737
After doing 100% charge I turned ON with vol+ pressed but phone did not respond (I guessed that it didn't worked, so switched ON normally) but after booting I found few settings to be reset so I guess it worked
So finally this trick seems to work for me, now the drain has slowed down to a lot extent. I have used phone regularly (calls, games, whatsapp, Music etc), the battery has dropped to 76% in around 8 hrs ( without stamina mode ) just expecting it to last for two days, and more than that with satmina mode.
Firmware: .77 (India)
Model: D5833
Hi Aakm,
As you said, the tricks mentioned so far on this thread were not really effective, at least for me as well. I could live with that 25-30% left at the end of the day (it is still much better than my old Samsung GS2), but I would be glad to be back to the 2-3 days of moderate use as I had during my first months of ownership.
So I'll try this out over the next days and hopefully it will work, thanks for suggesting! It sounds a bit like magic to me but let's give it a try
Best regards,
Alex
Unfortunately the full drain+charge did not change anything for me. I did not try to downgrade to Kitkat but as I've had good battery on Lollipop for several months, I doubt it would help.
Anyway thanks for your help, but I guess I'll simply wait until Android M comes out and take the opportunity for a full factory reset, hoping it will solve the issue.
Please guys mark the star on the bug report, the more people agree, higher will be the chance that google decide that it's time to fix it

sorry wrong theme

Battery life suddenly dropped and phone is always warm - How do I diagnose problem?

I searched and haven't found any battery life thread quite like the problem I am having.
I got my Nexus 6 new last September and until recently the battery has always lasted all day for me. I never looked at battery stats or tried to optimize because I never needed to. About a week ago, the battery started running out by 3PM every day. And the phone is always warm to the touch.
The only thing I can think of that changed was I noticed that my Google Contacts were not syncing properly and so I tried a bunch of stuff to get them syncing properly. I went through a checklist of stuff like wiping the contact apps data, deleting the google account and recreating, etc. I might have deleted and then installed the contact app, I'm not sure. I just tried a bunch of stuff until the contacts were syncing correctly. I don't think that is the cause - I mention it because it is the only change I can think of around the time the battery life degraded. I don't allow the play store to auto update apps, so other than something related to google contacts, there were no app version changes. I didn't change anything about how I use the phone.
I am running the ROM from here:
http://forum.xda-developers.com/nexus-6/development/rom-5-1lightromstock-lmy47e-03-19-2015-t3059493
which is, I believe, very close to stock. Since the May security patch level came out shortly after I started having battery life problems, I did a clean install of that version. I wiped system, cache, dalvik and data in TWRP before installing the new version. I've run that for a few days now and my battery life is still terrible and the phone is always warm.
Anyone have any ideas what could be causing the problem or how I can diagnose the problem? I've looked at the battery stats, but because I've never looked at them before, I have no idea what they are supposed to look like. The top item in the list is always "Android System" at 18 - 30% of the battery use.
is google play services eating a lot of the battery?
Or did you tried betterbatterystats? Or smth like that? So you can track in detail.

your phone is constantly awake, not sleeping. AND you have both Bluetooth and WiFi turned on. you'll get terrible battery. one way to rectify it, kinda, is to turn your screen brightness down a lot. since your phone is constantly awake, that means your CPU is working doing something, is it by your choice?

I want bluetooth and wifi always on and I have never had to turn them off to conserve battery before.
It sounds like the problem is the phone is awake all the time. Now how do I find out why?

you can use something like wakelock detector(app) to find if you have any unusual wakelocks.
I agree, it is abnormal for the phone to be awake the whole time from 9am-2pm including long periods when screen was off. The at 2pm (slgithly after you started charging), those wakelocks stopped and remained stopped even after you want back off the charger. It might be a clue... any idea what might have changed just after 2pm (some program that you stopped or killed or setting that you changed)? At any rate I agree something like better battery stats is a valuable tool to help narrow down the cause of wakelocks although it's not always easy.
Another thing I notice is that your phone signal is very weak... red orange and yellow. (mine is mostly green with a little yellow). They put that on the battery screen because it certainly can affect battery life as you phone has to work harder just to find/keep its signal. Weak signal might possibly be related to the wakelocks although I'm not sure. Most likely phone signal is something you can't control or wouldn't change, unless you were in a different location or unless (longshot) it is related to your radio. You might try flashing stock radio if you have a different radio.

Thanks for your help. I can't remember if I did anything that could have changed the behavior around 2PM, but now that I know, I can keep an eye out for any similar change.
I have never looked at the battery stats before, so I don't know if that cell signal is how it has always been or something that has changed recently. I suspect it has always been like that because I usually see 0 or 1 bars on the status bar icon when I am at home. I have not changed radios, but I may try that after figuring out this problem.
It looks like I need to look at wavelocks to try to see what is keeping the phone awake. I'll investigate and report back with results and or further questions.
Just remembering you said it started after the May security patch.
I'm assuming you flashed it rather than OTA'd it.
Here is the recent history of factory images for Nexus 6
FEB: MMB29Q

The MOB series introduced a new radio (the same new radio in MOB30D and MOB30I). I heard that the reason there are two imagesw in April and May is that not all carriers have tested/approved the new radio yet (those carriers - whoever they are - delivered OTA's to MMB29X and to MMB20G). I haven't heard any reports of problems from the new radio and I know it works fine for me on AT&T. Maybe if you came from something other than MOB30D before, and just changed to MOB30I in May, then it might be worth trying the radio from MMB30G instead (there shouldn't be any problem mixing/matching radios.. radio is independent of the rest of the image).

I just read you didn't change radio and you've always had a low signal. So, disregard my post above.
another thing - a standard troubleshooting suggestion (not related to anything in your post), try wiping cache in recovery.

What ROM are you currently running? Or kernel?

Just remembering you said it started after the May security patch.
I'm assuming you flashed it rather than OTA'd it.

It didn't start after the May security patch. It started a bit before and it started out of the blue. I did a clean install of the updated ROM with the may security patch. I was thinking the clean install of the ROM would fix it, but there was no change. One thing I didn't mention is that after installing the ROM, I restored system data and user apps and data with Titanium backup.

I am running the ROM here:
http://forum.xda-developers.com/nexus-6/development/rom-5-1lightromstock-lmy47e-03-19-2015-t3059493
I haven't done anything to change the kernel - does the kernel come with the ROM?
I have installed Wavelock detector free and poked around with it. I've attached a screenshot. It looks like the problem is in something labeled *backup* in the android system. Now that I have this info I am off to google android backup wakelock and see if I can find out more.
The problem went away for a while again and I can't think of anything I did other than install the wavelock detector app. Then the problem returned again.

Try this if it helps

Thank you all for your help. I looked at the google backup settings and I had backup turned on, but there was no backup account set. I put in my google account as the backup account. So far the problem is gone. That doesn't prove the missing account was the cause, so if the problem comes back, I think that disabling backup entirely should "fix" it.

Tremendous battery drain on WIFI

Hey guys, I am running stock 4.0.3 rooted with supersu and using the latest franco kernel. I am getting massive drains even while using the phone on wifi and keeping it on standby, while connected to wifi. Getting drains about 3.3-4% per hour on standby on wifi. This is absolutely crazy. I tried some older suggestions mentioned here https://forum.xda-developers.com/showpost.php?p=62074306&postcount=118 . But even that doesn't work. Battery drain is normal on mobile data, but when connected to wifi it absolutely goes crazy. Can anyone provide any insight? There are no rogue apps, I have been checking through better battery , wld , accu battery, etc.
You've probably already turned it off, but I'll just point it out in the rare instance, but make sure scanning is off. However, I did notice that you said it is when wifi is on and your phone is sleeping when you get that drain. A fix is to go into wifi settings and under "Keep Wi-fi on during sleep", pick the only plugged in option. Ideally, you should get to the bottom of this issue, but if you don't have the time and no one else figures it out, this may help.
EDIT: I wonder if smart wifi switcher has anything to do with it? Wifi connectivity fluctuates and if you have two connections that have very similar signal strength, would your phone constantly switch between the two networks in a futile manner? If this does happen, I can see that draining your battery significantly, but this is based on the premise that the switcher does not have some type of buffer zone where it does not switch if the difference is negligible.

Yep, I always keep scanning off! And i did try with that suggestion too, I changed the setting to never and it still drained battery. Wifi stayed on for sometime even though i set it to never and then finally turns off after a period of time, but i think that could potentially drain more battery? Are you using wifi all the time? What are your stats?
I have all those settings turned off, smart switcher, ipv6, scanning, etc

Last thing I can think of is trying to use stock kernel to see if it is FK that is the culprit. FK shouldn't be the issue, but perhaps something screwed up during the flashing process? Now I'm essentially just asking you to do trial and error

Nah man, I trust FK more than stock
I have had similar issues with stock as well.
What are your battery statistics?

Note that I'm in Beta 3 and running its stock kernel so I don't really see the usefulness of giving my battery stats, but yes, battery life for me has been good and unaffected by wifi draining.

Whoa, how the hell do you even get 2 hours 17 mins sot with 85% still remaining?
Is it really just me suffering from this wifi drain bug?

It's most likely not just you, but based on my perusal of the 3T forums (especially on the FK thread because that's most relevant to how you set up your phone), not many people are facing this issue. Does betterbattery stats not show anything funky or out of the ordinary? Can you post a screenshot of your betterybattery stats including the kernel wakelocks, alarms, and partial wakelocks page?

Check these out. I am totally fed up. I think I might have a faulty unit.
Getting 4% drain on standby!

I'm beginning to think it's not wifi, but the app Saavn. It may act differently when on wifi vs on cellular data and remain active constantly when on wifi. I google searched the app and its potential of being poorly optimized app, and there are reports of it never turning off and running in the background. If that is the case, it should be showing up on BBS as more of a drain, but for some reason it isn't. Still, try uninstalling the app and see what happens.
In the end, if this doesn't solve the issue, I'm beginning to think a factory reset maybe in order. I wish you also gave me BBS alarm wakeups page because that would help see if Saavn is constantly firing off alarms or not.
Go to your "Location settings" and into the 3 dot menu in upper right. Turn everything off.
do you have wifi calling on? turn it off and see

I don't have any option to turn off wifi calling in there. I am running the beta 7.1.1 now though. But the problem still persists. Too much drain when using wifi, it's being shown as android system drain. I've seen many people reporting it, so it's not just me. But for the life of me, I can't figure out what's causing it!
Issue resolved with latest 4.1.0 and some usage pattern changes. Mod, please close the thread. Thank you!
