baseband_xmm_power kernel wakelock drains my battery! - Nexus 7 Q&A, Help & Troubleshooting

Hi, I don't know what to do, I'm running 4.2.1 stock on my 32 3G N7. The tablet cannot go in deep sleep because of constant baseband_xmm_power kernel wakelocks. I tried factory reset, but the problem persists. For example with 5h the screen off, there are >4 hours partial kernel wakelocks.

Same here and I'm sick of it. Sometimes my Nexus manages to enter deep sleep but I still see a significant percentage of that kernel wakelock. It also happens that wifi won't shut off on sleep, and I'm talking about when it truly enters deep sleep, and it's correctly configured.

I have the same problem. Battery life is really poor due to this. My LP core is running at full tilt for at least half the time the screen is off, preventing deep sleep.
I found a suggestion that turning on flight mode and then rebooting might help, but I think the problem recurs pretty quickly if not immediately.
Saw a post that said it's due to the modem switching power levels when radio reception is poor. That would definitely make sense in my case — 3G reception fluctuates a lot at home and I am constantly losing connection. I have removed the SIM and will check it in the morning to see if there's any improvement. (Using BetterBatteryStats).
Hope this bug gets fixed in the next update. Almost thinking I should have got the vanilla wifi model
________________
EDIT: Removing SIM overnight doesn't help. Over the course of 8h screen off, baseband_xmm_power was active for 7h 46m!

I'm having the same problem, only when mobile reception is poor. Unfortunately, my mobile coverage at home is currently near-zero, which makes using my tablet as an alarm clock a dicey proposition unless I plug it in overnight.

[Q] A few questions.

First of all, I'm doing this guide (wiki[dot]cyanogenmod[dot]com/wiki/Troubleshooting#Battery_recalibration) since I recently rooted and flashed CyanogenMod 7.0.3. One of my questions was this: What's the quickest way to drain my battery? Currently, I have airplane mode off, wifi on, sync on, GPS/Navigation on, and I'm watching a Netflix movie with the screen at the brightest setting. It's been like this for maybe ten minutes and it's still at 100%. Since I'm going to sleep soon, I was hoping it would be quicker to eat up the battery.
Secondly: 'Cell Standby' keeps eating up all my battery. Seeing as how I don't have a cell coverage plan and I always use my phone with airplane mode (with wifi on), why does 'Cell Standby' use so much power?
Anyways, does anyone have any more battery saving options? I wouldn't like to turn off wifi or sync.

Have you tried different radios? also you can overclock and undervolt, those all can make a huge difference in your battery life.
Set you brightness to a low level and turn off auto brightness.
Use a darker colored background,this will normally use less lcd power.
Also GPS can eat up alot of battery.
You may want to change your sync/ push options to update less often.
Not too familiar with the cell standby eating up battery life, normally with airplane mode this should stop the phone from searching for service. also try battery calibration after you install any rom. you can find this in the market.
Hope this was somewhat helpful.
good luck!

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.
Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.
Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.
Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??
You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.
Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?
Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.
I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note
I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

[Q] Fluctuating Battery Usage Overnight - Why?

I have a new Samsung S4. Trying to learn how best to configure it to minimise battery usage and to ensure I don't install apps that eat battery. There's nothing wrong with it, battery usage is fine, just trying to get the best out of it; whilst keeping as much functionality as possible without having to constantly turn things on and off. I'm trying to avoid rooting it.
As a starting point, I'm checking usage overnight, when blocking mode and power saving are on, with wi-fi and data off; but with the alarm clock set.
I have an i-onik 7.85" tablet on Android 4.2.2 - with a deep sleep battery saver app set to slumberer ("always deep sleep when screen off") it only uses about 2% of battery overnight - the battery currently holds about 3600 mAh - so that 3% equates to 108mAh.
First time I tested my Samsung S4 (the european LTE version 9505), (actually I think I had wifi, data, location setting turned on and power saving turned off), it used 4% battery overnight. Not bad, 4% of 2600 mAh is 104 mAh. Still I thought I might do better. I tried the deep sleep app on slumberer but inexplicably the usage then jumped to 12% (whereas it at least halves battery usage on my tablet). I've since un-installed deep sleep battery saver and started turning off wi-fi, data, and turning on power saving - so I'd expect it to use 4% or less battery overnight.
The actual battery usage instead increased to around 9% to 12% - although the settings used might have varied.
Three nights ago I made sure that all apps were closed, and everything turned off as above - battery usage overnight was still 9%. I used WakeLock Detector and found that a Morrisons App was causing wakelocks. I uninstalled that, and the next night the battery usages was down to 6% with much fewer wakelocks. Still not as good as before though.
I then found there were wakelocks due hotmail and gmail sync - hotmail I changed from push sync to sync every 4 hours, gmail I changed from hourly sync to manual sync and I also turned off master sync. I also turned off location setting. That cleared the wakelocks for these apps, but battery usage last night had increased to 9%.
So, despite the same settings and less wakelocks (and it was in deep sleep all night except for 16 minutes), battery usage increased from 6% to 9% - still no where near the 4% I had at the start despite making various changes that should reduce battery consumption.
The only significant wakelocks last night were:
com.domobile.applock (via alarmManager) awake 35s giving 992 cpu wakelocks
com.google.android.google (google app) 7 wakeups
Can anyone think of any cause for increased battery usage from 6% to 9% despite more time in deepsleep, less wakelocks (other than the 2 above but there were many more wakelocks the night before lasting several minutes) and location setting turned off. I wonder about starting again from a factory reset ... NB every night before going to bed I've rebooted the phone, and charged it to between 90% and 96% and it's been tested over the same period of time. Is it normal for battery usage when the phone is sleeping to vary so much?
Charging the battery inconsistently might lower the battery life. And letting it discharge to much does the same. I generally avoid letting it go under 50% and unplugging it before 100%.
I don't know what causes your issues, but if you want full control over your phone, you will have to root.
I also had 2% drain over night at some point, but now I have 4%. But this may also be rom related.
Thanks. I'm on stock ROM. I have rooted other devices but then find some apps don't work, and of course I want to maintain my warranty.
Each day my battery is generally dropping to about 30% at which point I charge it up to between 90% and 95% before turning turning most things off ready for bed.
At some point I may leave it plugged in overnight instead - is that a bad thing?
What do you mean by charging inconsistently? Sometimes my battery may be around 50% though more often around 30% when I start it charging.

By charging inconsistently I mean exactly what you said. You charge between 90 and 95% generally, instead of leaving it to charge 100%.
Somebody said that if you live in the EU you will not lose your consumer rights. I guess that includes the right to have your phone repaired because it is in warranty. Other people have reported that the phone service accepted and repaired their phone even though it had knox flag 0x1.
There isn't much you can do on stock unrooted roms in order to reduce battery consumption.
You battery drain is probably caused by weak signal strength. Having bad signal uses more battery. The screen and the phone radio use the most power on the phone. If you put our phone in airplane mode there should be almost no battery loss. If everything is turned off.
On my old device I used to put in airplane mode during the night. I had 0% drain over night in airplane mode.

Thanks - that's a good point about signal - my mobile signal and wi-fi signal does seem to vary, so that could contribute to fluctuating battery usage. I decided to test that by using airplane mode and have started charging to 100% on your advice. Unfortunately when trying to dismiss the prompt to upgrade to lollipop, I accidentally started the upgrade, with no way to cancel it. (For me, lollipop really seems a downgrade, I've lost a lot of functionality I used all the time in KitKat).
The bad news it that on lollipop overnight last night, despite using power saving mode and airplane mode, and basically everything else off including sync, it lost 7% of battery.
So I decided to do a factory reset, thinking it would go back to KitKat - but it didn't - it stayed on lollipop. It did give me the option to choose which extra apps to install (including some Samsung ones) - I declined to install any extra apps, and also turned off automatic app updates - I then turned off sync, backup and anything else that I thought might eat battery - leaving the phone with the most basic set up possible. I've not since installed any apps except Talk2Go.
The good news it that since the "factory reset" to lollipop, I've tested it for two periods of 4.5 hours on airplane mode, everything off, and I did not turn on power saving mode. The battery lost less than 1% - in fact for my last test it stayed at 100%. So either the reset fixed battery loss on lollipop, or the power saving mode was actually causing battery loss!
I'll investigate that and report back for the benefit of other users. I'll then gradually update my settings and see what, if anything causes battery usage to increase when on airplane mode. Of course it's also possible that battery usage might increase without changing anything, as per some reports from those upgraded to Lollipop - if so I'll report on that - and confirm if a reset seems fixes it.
Lollipop is supposed to have a battery saver mode - but it seems to be missing in the stock OTA update to S4 - does anyone know how to use this mode? It sounds better than Samsung's own power saving mode (especially since that might actually be causing battery drain rather than saving battery!)

Samsung probably replaced the stock lollipop battery saver with their own battery saver.
You could return to kitkat by flashing via Odin. Doing so will not give you knox status 0x1 and you don't even need root.
On second thought, you have the new bootloader so you probably won't be able to do it without tripping knox..
From what I saw, battery saver changes only the minimum screen brightness to a lower value than normal and it changes the CPU governor to a more battery friendly one.
This is what I observed on the GPE rom battery saver mode.
Testing continues - for the first few nights battery drain was less than 2% on airplane mode, but it wasn't repeated last night. It drained 9% with exactly the same settings (ie everything off except the alarm clock, no foreground processes running and airplane mode on).
I've installed a few apps - one from TalkTalk, one from Three Mobile, a terminal emulator and wakelocks detector. So have now uinstalled the first 2 to see if they are causing the drain - BUT I suspect it's a bug in this release of Android Lollipop.

Many people have problems with the stock lollipop. Samsung messed up.
It might also be the battery. I have my phone since november. My battery used to drain 2% over night. Now it drains 4% over night. Basically it drains very fast to 96%, from there it drains normaly, depending on the usage. This happens on every rom I tried and with even the most battery oriented settings.
You seem to be using applock. If you don't need it you can delete it and get rid of a few wakelocks.

Cell Standby Battery Drain

Hey everyone,
I picked up a T2 on Thursday morning coming from a Maxx, and after the first day I felt I wasn't getting quite the battery life I should. After watching the battery stats and doing some research, the issue seems to be due to Lollipop's well-documented cell standby bug. Coming from KitKat I have been pretty frustrated by this, as my T2 will sometimes drain 5% or more in an hour of idling if WiFi (or possibly Bluetooth) is on, and seems to drain much faster with use if WiFi is on. (Note that all of this is taking place in areas with very strong 4g and WiFi signal).
When WiFi is turned on, Cell Standby tops the battery consumption chart by a large margin and my unscientific eyeball test suggests that the battery drains much faster.
Is anyone else having this issue? I'm considering taking the T2 back, but honestly there aren't any other new phones with comparable battery life, and it would be hard to give up the shatterproof display. Other than this I'm loving the phone and Lollipop.
Thanks!
I'm not having that issue at all and I leave my WiFi on pretty much all the time. I just checked mine and in 13 hrs my cell standby was 8%. Honestly idk if that's good or bad.
I guess I'll just keep an eye on it. Over this past night Cell Standby was on for 10 hours and had the Mobile Radio on for 8 hours while the phone was idle. Not sure if this is intended or not. My battery woes could just be in my head.
cell standby has been near or at the top of all 3 of my Verizon Lollipop phones so dont believe its a Turbo 2 direct issue.
I guess I'll just be patiently awaiting marshmallow then!
Try this, idk if it'll help or not but under WiFi settings under keep WiFi on during sleep, choose only when charging.

I've also read this cell standby time is related to WiFi and possible fixes are as follows. Turn off allow Google to scan for networks even if off, keep WiFi on during sleep charge only, LTE instead of global, and then go into recovery and clear cache. This is what I did and my cell drain is very low. Hope it helps.

Thanks for the tips - I changed all the settings but I'm having trouble getting into recover. When I try to launch from the bootloader I just get the dead Android with "No Command" displayed below it. Is there something I'm missing? FWIW I have dev mode on and unlock oem bootloader on.
I wouldn't turn on unlock boot loader this disables some security features and unless we have a way to truly unlock it. It's better to leave on. Dev mode doesn't affect drain issue at all. Here's link for booting into recovery.

Got it. Thanks for the help!
Mine drains fast while sleeping at home. In my case, the signal is poor so the phone has to crank up the radio power, draining the battery.
UPDATE: For anyone interested, the fixes suggested in this thread seem to have done the trick for me. After changing settings and wiping cache I am getting even better battery life (7-8 hours of screen on time up from 5-6 in similar conditions). This could, of course, be due to other factors - but hey, it's worth a shot if your battery is draining quickly!

Which lte did you pick? There is 2 options. Also how do you get into recovery? Thanks
LTE/CDMA
I personally have noticed that turning off mobile data when connected to WiFi helps. I have done this with previous phones
I experienced this the other day after spending the weekend in an area with spotty service. To fix all I did was reboot the phone.

LG V20 Battery drains on "Phone Idle" and Wifi is always on.

Hi guys,
Hope you all doing great.
Guys i have LG V20 n using from last year. It was working great without any issue. Battery timing was awesome. Giving me 5:30 to 6 hours screen on time. Almost day and Half on normal use. 2 days back something happened no idea what. Now phone idle using more then screen on time and wifi is always on even its off. I tired to uninstall app, then factory reset but still same.... No luck.... Any solution ??
Go to your location setting use the tab in upper right, click setting and turn wifi scanning off.
I tried this but no luck
As i mentioned i tried everything thing, like location off, wifi and Bluetooth scanning off, play services off, Almost everything is off, but still same. No luck...

Try to install battery monitor application (I use betterbatterystats) to find out what is causing your idle drain. But to be honest, I've never got 5-6 SOT. My idle drain is about 0,7% per hour with greenify, managed Google play services wakeup, custom kernel, kernel adiutor and about 80 apps on board.
I'll try and help the best I can..
Within the last year or so..I have been reading about this issue quite often. That is, people posting about "Phone Idle" having high percentage in battery stats. And then they are off to hunt down the culprit. The truth is, "Phone Idle" is NOT eating up your battery. Phone Idle is just that.... Time the phone has spent being idle (being still, or CPU/Battery not being used). Or in this case, percentage of total battery "usage" that belongs to "Phone Idle". In actuality, phone idle isn't "using" anything. The "usage" for phone idle is really time NOT used. A higher percentage is better. If your phone sat for 2 days straight without being used...the phone idle % will be real high. Also, you can't "Greenify" phone idle. You only greenify phone idle when you greenify other apps.....think about it.
And as for Wifi. The Wifi radio on this phone is a bit more power hungry. It doesn't even include any power saving options that some phones, like my Samsung S4 has. My S4 used on average from 2% - 6% depending on signal strength. The V20 can use from 7% - 11% ..again depending on signal strength. If you leave Wifi on overnight and it's in bad proximity to the router..10-11% is normal.
What is your average signal strength for your 4G and cellular (calls)? CDMA has 1X, I'm not sure what GSM uses. If it's in the high 90's and higher, that right there could be chewing up your battery. Phone radio often doesn't even show on the usage list.
How often do you need to charge? Also how much time between a charge and what is your usual screen on time now..after you wrote this post? Phone idle is only at the top because the "idle" time now exceeds the amount of time you have your screen on. ......don't take this the wrong way but some people think the phone idle is actually something that's draining the battery. It's not..it's just placed within the list. Ignore the Mah it shows for it. That just assumes it's some app and it tries to convert everything into mah..and I really don't know how accurate that is. But it obviously doesn't apply to Phone Idle. Speaking of...what is the amount of phone idle time?
