nexus 5, battery stats screen shows miscellaneous, but there's no info on it at all. what does it mean? there was no miscellaneous in the 4.4 builds.

Same here. Miscellaneous dominates battery usage at 63%. My Nexus 5 is extremely hot.

I just noticed this issue yesterday while using the camera application. I had recorded a video, and then when I stopped the camera app seemed froze, no anr though. I locked the device. I noticed later that it was pretty hot, and looked at the battery stats and misc was really high, but there was no details on what exactly had been heating up the device and draining my batt.

Thank you for reporting this issue. We will pass this along to the development team and provide updates as they are available.

My issue remains even after rebooting, but I can provide logs if necessary. (re: 614) Would like to share via google doc etc, but not release it to general public on the bug reporting page.

Thank you for reporting this issue. We have passed this on to the development team and will update this issue with more information as it becomes available.

I'm getting the same.. miscellaneous using up 35% of my battery and screen only 2%

Issue 641 has been merged into this issue.

Yesterday I disabled LTE as the preferred network type and suddenly battery life had become much more realistic and ol' Miscellaneous seems to have calmed down (instructions: http://goo.gl/lpN9pH). There is still a lot of "Miscellaneous" battery usage (20% atm, Screen 6%, GMS 5%, OS 3%, System 2%), but battery life is closer to what it was on 4.4.

for what its worth: - Nexus 5 - Provider doesn't actually support LTE

mbre...@gmail.com - were you using LTE as your connection before disabling it? I don't have LTE where I live, so I'm wondering if disabling it, even when it's not available will have a noticeable effect.

My phone was set to LTE, but my provider doesn't actually offer LTE (yet...)

I've made the change- will report back if there's any noticeable difference.

I've had LTE disabled all along, but still have the issue. Nexus 5 on Ting (on Sprint network)

Disabling LTE seemed to work at first, just as restarting the phone does (at least 1 out of 5 times) but as soon as my alarm went off today morning (for about 15mins straight until I stopped it) my battery went down from about 65% to 30% within the next hour with LTE disabled.

I guess i have to keep restarting the phone for now :(

Also having issues w/ Miscellaneous battery usage. I read a thread on XDA that said re-locking the bootloader resolved the issue. Attempting now.

Issue 813 has been merged into this issue.

here's a bugreport for my duplicated issue #235 which has been merged here on https://code.google.com/p/android-developer-preview/issues/detail?id=235 for Slow UI Performance on 3G Network.

I saw lots of GC pauses and Jank Perceptible above 16ms. This bugreport is taken at noon when ambient temperature was around 30-33C outdoor on 3G connection and the battery temperature was around 38-42C. The transition animation was getting a lot of random jank.

Hope the final release of Android L will triumph smooth 60fps UI performance across all animation and scrolling on 3G connection and when the SOC throttles down to 1Ghz due to thermal throttling, or even when SoC is down to 700MHz such as in battery saver mode enabled. This will make the User Experience better for all of us who use Android on tropical country and on slow unreliable 3G connection.

peace :P

By disabling 4g and NFC the problem is gone. I'll try to reenable one by one in order to identify which is the problem.

I'm disabling NFC only. Someone should try 4g only. On Jul 18, 2014 10:05 AM, wrote:

I confirm that the clue is in NFC, i've reenabled the 4g and the problem is not came back.

Yes. I tried disabling NFC too and the problem improved. Miscellaneous still takes up a larger percentage than anything else but no where near as bad as before

I will also try to disable NFC, thanks for the info

I have seen my Nexus 5 running Android "L" with over 100% battery usage in "misc" a few times now. Here is a screenshot. I don't think the battery usage feature is working properly if this is occurring. It potentially calls into question ALL battery statistics on Android.

Proof:

The battery usage stats don't reset until the phone is fully charged. Since you recharged a few times, the stats kept going up, hence why you have over 100%.

Issue 966 has been merged into this issue.

Thank you for reporting this issue. We were able to reproduce the issue on the public L Developer Preview build. However, the issue is not reproducible in our internal development build (which is ahead of the public release).

Hi Basak,

Can you confirm if the release yesterday was upstream enough to have resolved this. From what I've read so far, it only related to Google Fit support?

Thanks, Aran

My miscellaneous battery drain issue appears to be related to the NFC function. If the tablet gets near another NFC device, I see the power drain. Force stopping the NFC service fixes it.

Issue 1216 has been merged into this issue.

Issue 1367 has been merged into this issue.

NFC has made no difference to my build, has been disabled from day 1 and still getting very high miscellaneous battery use! 45& miscellaneous 9% screen

Issue 1425 has been merged into this issue.

After re-lock of bootloader the problem is solved.

Not for me. Miscellaneous always present, even with bootloader locked.

Issue 1527 has been merged into this issue.

Issue 1556 has been merged into this issue.

This issue is being investigated. We will provide updates as they are available.

This issue is also true on 2013 N7 wifi, miscellaneous is at the top of battery usage at 30%, with screen at 6% and the rest at 3% & below. Running the latest Lollipop preview image, NFC off.

I'm still having this issue on my N5 after the recent Dev Preview build (LPX13D). Seems to be particularly bad when connected to work wifi (close to 50% at one point!)

I got mine sitting at the top with 26% on Nexus 5 running Android LPX13D. Hope the attached bugreport helps.

Kudos for the smoother Android System UI experience though! :) Let's wait for other apps to follow. Keep improving for smoother, more responsive, faster, and jankfree Android even on when the device is in thermal throttling and/or in battery saver mode.

For info : I wiped more than 5 times with the factory image of Android L. There's absolutly nothing left in my Nexus 5. I deleted every single Android informations stocked in my google account from the dashboard. I have no applications whatsoever, except the very basic stuff provided by Google. Except from browsing, my battery is getting drained hard. Google Now is deactivated, Google location too. Wifi is always off when it's sleeping. How can I fill a bugreport to help you find the source of the battery drain ?

@Tovarich. Turn off NFC. Go into about phone and tap on build number a bunch of times until it enables Dev mode, then tick low power mode.

@SubTrac FYI: It appears that the low power mode setting is no longer available in last week's new build. At least, I'm not finding it.

@SubTrac : NFC is already off and the low power mode is not there. The 4 other options are there, but not the "low power mode". It was in the previous Android L build however.

Battery saver is in Settings > Battery > 3-dot menu.

I've got the same problem.

I rebbooted the phone and the drain kept going, i could not even charge the phone via usb (not enoough power).

Everything is back to normal after turning off wifi.

After analyzing the battery graph i saw the strange battery drain only happened when i was at work connected to the entreprise wifi (PEAP with MSCHAPV2 authentication). Everything normal at home (wpa2)

Running the latest DP.

My Nexus 5 (LPX13D) has the same problem.

Similar issues on my Nexus 5 running LPX13D. Miscellaneous is nearly always at the top of the battery statistics.

@nyeincha : even with this battery save mode, it's draining.

I have this defect too. Miscellaneous has drained 53% of the battery.

For me, and this might be a placebo, this was caused by "Chrome". Once Chrome was removed, I haven't even seen Miscellaneous in the battery log.

Can anyone else confirm?

Comment deleted

I'm sure I used to have this same issue on KitKat but because there was no "miscellaneous" option, the drain was lumped in with "Android OS". Again, might be a red herring, but those particular issues seemed to get a lot worse after the Google Play Services 6.1.xx update which contained Fitness APIs I believe.

I can confirm that wakelocks and battery drain happen when connected to PEAP authentication WiFi.

I had hoped this issue was with the initial android l version I was running, but after the update my battery on my nexus 5 still is horrid. I use a EAP WiFi network on my campus. I will try a few days with that off to see if it seems to effect this.

Someone else may have mentioned this, but I don't believe these are new source of battery drain.

I believe that this "Miscellaneous" label is a collective label for those battery drain sources that the Android team hasn't been able to identify/classify, yet.

Yes, it's kind of bad that such significant portion of the battery drain hasn't been identified/classified, but I don't think this is really anything new (probably something in the OS level).

If they can't find all the battery drain sources, at least, they can give a better (less alarming) name/title for this label.

My computed power use is 992mAh, vs. an actual power use of 1679mAh. I honestly don't see how this much power is being used in a way Android can't cope with.

There's definitely at least one major new drain, as my battery is being drained significantly faster than on KitKat. I have tested with WiFi on and off, and it doesn't seem to affect the rate the battery is drained very much; both still consistently yield Miscellaneous being the primary drain with it consuming 40-50% of the battery. My WiFi is encrypted with WPA2-Personal. "Miscellaneous" is draining much more power than the screen is, even when the screen is on the entire time.

Maybe those can help...i dont use nfc at all but i keep getting high usage of Miscellaneous drain

BTW 2+hours of audio??i dont use any app with audio so long...

I'm seeing this too. 70% battery drain reported as being caused by "Miscellaneous." Nexus 5 with Lollipop.

Im also have this issue its taking double the battery then my screen!

same here. at first i thought it was an application because in the first 3 days with lollipop everything was fine, now i did a factory data reset and still have the same miscellaneous drain

getting the same 52% Miscellaneous nexus 5 LPX13D

Turning off NFC, LTE, and finally Location Services removes this rogue battery drain from my Nexus 5. If I turn Location Services back on, the "Miscellaneous" drain reappears.

Location Services as in Location Reporting found in the Location section of Settings? Or location at all? Or some other arcane hidden setting?

Same problem. Battery life is about 3-4 hours on a Nexus 5. Even with NFC off and wifi off (so only connected to my cell network's LTE).

Have not tried the above suggestion of turning off Location Services; I merely downgraded back to 4.4.4 because I am not near outlets during the workweek in case it did not work.

I was able to eliminate the drain by turning off the "Scanning always available" setting that's in the Wi-Fi screen's Advanced menu (for me, turning off Location Services had no effect).

Same for my Nexus 5 on LPX13D. Misc.: 52%, 1400 mAh computed vs 2600 observed power use. If this is some collective description, could you please provide this bit of information to the user!? This would help a lot to avoid confusion.

Almost two weeks using Nexus 5 on this LPX13D build, I notice the phone often runs hot. Never had the warm to hot feeling when touching the upper and bottom part of the phone on KitKat though.

The battery temperature easily reaches 45C if using it for a while and on average it ranges between 40 to 45C.

I know September and October is the hottest of all in Indonesia and as I recall, old Nexus 4 back then on Jelly Bean didn't experience the above symptom at all.

Confirming I have also experienced this issue under lpx13d. Averaged around 50% misc. and the issue started suddenly after around a week of flawless performance. None of the above suggested fixes seemed to work. I am currently travelling in the US and am using Google maps and Uber a lot, so lots of location services activity. Phone eventually ended up in a boot loop and I ended up having to downgrade the phone to 4.4.4 using fastboot after formatting via recovery partition.

Probably worth noting that the phone was rooted and had Chainfire's custom android L kernel installed, though I don't believe this to be the cause of the issue.

The suggestion about in #81 seems to have done a good job of extending the battery life. Even more so when the WiFi is off entirely. (And the drain is worse when not connected to a WiFi network with the WiFi on than when connected to a network.)

The battery stats still state that Miscellaneous is BY FAR the biggest battery user, but I care a lot less about that since the battery life is usable.

I've found that turning off my phone, and removing the non-removable battery fixes the issue.

Another day, another time that Miscellaneous is the power user #1. :( Other than that, today I noticed that there are two entries for what supposed to be the same: "Android OS" and "Android System"!? What's even more confusing is that they both show completely different stats for the CPU usage!?

I'd really like to get some official feedback / clarification here; rather than hacky guesses (no means!).

It was said that the problem was resolved in the internal tree, which should have been ahead to public release. That was before the final 5.0 SDK and the LPX13D Preview builds have been released. So one might assume that "this issue" should not be present in the LPX13D builds. Well, as repeatedly reported, there's still an issue here. And if it's just the clarification about what exactly "Miscellaneous" stands for. (though, a look at the verbose sensor and battery manager logcat logs suggest that there's really something not working the way its supposed to be. And that it is related to connectivity (especially WiFi, but also GPS really suck)).

And please, could we get a non-boilerplate answer this time? Thanks for acknowledgment!

Another day, another time that Miscellaneous is the power user #1 - 61%. And again, "Android OS" and "Android System" showing completely different stats. Seems like it's getting worse day by day. :(

I got an interface issue after turning on the power saver mode. The statusbar and navigation bar turned into orange colour. Openning other apps with material design doesn't change it.

The red in the nav and status bar when in battery saver mode is intensional. But I will add its ugly and a little too in your face for alerting why device preformance may be poor.

This might help. I tried a whole day without WiFi on, just to see if something is different... and yes ! Without the WiFi on, the draining problem vanished in a big part. The "miscellaneous" is not there anymore.

Anyone dangerous enough to try and run latest L with kitkat radio?see if its the radio?

I have flashed the 4.4.4 radio and saw no difference.

I also saw the battery stats using battery historian...and nothing out of the ordinary....just a Audio+ usage 100% that it isn't the audio out neither the phone calls!!!

I installed the 4.4.2 radio and battery consumption seems to have improved. I had heard that the 4.4.4 radio was also the potential cause of battery issues so I went right back to 4.4.2.

Consumption now appears "normal" (1% an hour on idle rather than 2 or 3%) for the last 4 days since I took this action so hopefully it remains so...

Android Engineering is aware of an issue affecting Nexus 5 users running Android 5.0 which causes significant "Miscellaneous" battery usage while WiFi is enabled. This appears to be caused by an abnormally high number of IRQ wakeup events.

We are continuing to investigate this issue.

Re #98 Thanks for the comment, Trevor! The unusual high number of IRQ wakeup events is definitively something I can confirm for myself.

So just to get your comment on "ongoing investigation" right; At this time the issue is NOT resolved. Neither in the (latest) public souces nor in your internal code branches. Correct? Thanks again.

99: Correct. This issue is still open and has not been fixed yet.

so what is the recommended course of action to minimize the battery drain? keep WiFi off as much as possible? and flashing the 4.4.2 radio as someone else mentioned?

101: At this time, turning WiFi off when it's not needed seems to be the most commonly recommended workaround.

I can't comment on using an older radio version, as this configuration has not been tested by engineering. In general, radio images are tightly paired with system images, and we do not support or recommend using an incorrect radio version.

alright. thanks a lot and good luck finding the problem !

Mine is worse

Mine is at 35-40% (no screenshot)

Trevor: Has this issue been investigated on the Nexus 6 software internally? The IRQ wakeup events could explain the unusual shorter rated battery life on WiFi vs LTE from the product page (Rated: 9.5 Hrs Wifi, 10 Hrs LTE). Typically, the opposite is true and the presence of this bug in the Nexus 6 5.0 software would explain the diminished rating.

is this issue only for nexus 5 or for all nexus devices?

In case this is helpful for the engineering team to track down this bug:

When I switch between two adjacent buildings wifi, it will cripple the entire network for a few minutes.

So, right now, if I walk away to the nearby building, everyone in that building goes "the internet is down again!". Then, when I come back everyone in my office groans because they lose their connection for a few minutes :)

I am seeing the same sort of issues as yetAnoth... above me.

I am seeing horrible network issues anytime I enable wifi on my Nexus5 in my home. If I arrive home and have wifi on it freezes everybody's ability to use pretty much anything for a couple of minutes.

The new handoffs could be causing the issue.

@trevorjohns@google.com A further look at my logs suggest that, when WiFi is enabled, the phone is being kept awake permanently by "suspend_backoff" (and (almost) never goes into deep sleep)?! Additionally, I recognized a bunch of related, contextual permission denies for the radio.

When I just saw this, 2 things came to my mind:

1.) The discussed behavior here looks pretty much like an older suspend_backoff bug in BlueDroid; where BlueDroid sent disable calls to already disabled rfkill (which in turn caused unbalanced IRQs, which finally prevented the device from going to sleep).

2.) I'm not too much into SELinux.. But with all the recent restrictions and seeing all the permission denied logs, a first guess was that IRQs are maybe being send in the wrong context and/or not being considered in some SE policy!?

I'll have a further look into my logs tomorrow and provide the relevant parts of the logs here for further investigation (writing from my phone and also need to filter the relevant infos first). But it would be great if you, Trevor, could give a quick feedback whether SE related changes/restrictions may be the actual reason for a wrong context here. Thanks again.

This issue has been fixed in the latest builds, and this issue is now considered resolved. Thanks everyone.

Hallelujah!!!

Re #112: Thanks for the fix. However, I can't find a related change in Gerrit (except for maybe 112825, but that targeted the 3.1 kernel only).

So in order

• for those who tried to narrow this down to have a learning affect AND (more importantly)
• for all users to be able to -- keep further track of this issue -- check whether the suggested fix, really fixed one's issue,

could you please add a quick info about the cause of this issue (ie what was fixed)? Alternatively, a pointer to Gerrit would be completely satisfyingly too.

Thanks very much!

So is it now ready to be distributed to the nexus devices :D

Re #113 - #137, #140: Gosh, this is a bug tracker; not the Android Police discussion forum. Thanks for not cluttering. Not.

PS: Just because AP said that this issue might be a valid reasone for postponing the N5 OTAs, this is NOT necessarily true! So please stop asking for OTAs here! You just clutter some people's inbox with irrelevant msgs. Thanks!
