Doze doesn't seem to work - Nexus 9 Q&A, Help & Troubleshooting

Hello, everyone!
With the new update on Android 6.0 I was pretty curious to see how the new feature "Doze" will work.
Unfortunately it seems that it's not working for my device.
Can you please give me some advice to figure out a solution?
Here is a screenshot, showing my battery stats.

Nobody who can help?
I tried changing the WLAN frequency to 2,4 GHz, but nothing happened.
The battery only drops very slowly when deactivating WLAN... But that can't be the Doze feature, isn't it?

Here's an app that let's you adjust your doze settings. Maybe you can use it to make your N9 doze sooner and longer.

There is a known issue with DOZE and WIFI on the Nexus 5 that affects some but obviously not all.
I had the same problem on my N5 that was resolved by completely disabling WIFI.
I don't have any issues with Doze on my N9 but I do have wifi set to off when screen is off and device isn't plugged in so maybe that's an option as well.

That second option sounds interesting. So you know if this setting (WiFi set to off when screen is off) affect apps like Spotify? It should not interrupt the playback via Spotify when screen will be off.
I'm asking because I can't try it at the moment. A friend of mine got my tablet until Sunday...

It's in the advanced wifi settings and it's actually called "Keep WIFI on during Sleep" and the options are always, only when plugged in and never.
I actually went back and looked at the pic you posted and it looks are though you got 4+ days of life (uplugged around Nov 4th and looks like it is around Nov 8th) and you are still at 28%.
I don't think there is anything abnormal assuming the tablet was indeed in use periodically during that time.
My tablet, when NOT in use at all (sitting in a drawer) will consume around 3% battery over a 15 hour window. But that can drastically change if I use it at all during that time.

Jelly Bean Location Service Battery drain.

So hi guys!
I have a question regarding the location service of JB. I'm talking about the google location service over wireless connection - not gps.
I have two devices - both running jelly bean. I have Google now completely disabled also i ticked off location history, i simply want to use location for stuff like weather apps and maps, so i see where i am when i open the map.
I have this feature enabled since i was running Froyo on my Desire back in the days And it was never an issue in terms of battery drain.
But now its just aweful. On both my devices i can basically DOUBLE the standby time when i disable the location service... And if i check BetterBatteryStats app it always places location services in first place for wakelocks.
Here comes the question: Is this a general Bug on Jelly Bean or is there a way to make it behave like it did on ICS or GB? I dont need it to update every 1min or whatever it does to drain my battery... Once every hour is more than sufficient! Are there settings for this somewhere?
See Screenshot on how it looks like on my Transformer prime. For my SGS III this would show up as Android-System, but its the same thing in BetterBatteryStats.
cheers!

I have been wondering the same thing. What I don't understand is why the drain is so bad even on Wifi. I don't know much about coding, but it seems like there should be no reason to check your location as long as you are on a Wifi network because obviously you haven't moved far since you are still connected. I have over 30 minutes held awake by maps and never left my Wifi network.

Map applications are the most power drain , it must open the wireless network and GPS,They are all power consumption
Well at least i'm not alone anyway i disabled the location services on my devices for the moment and only enable them when i need it. Big improvement in standby drain! Its a workaround but no solution...
cheers

Maybe you can use One Power Guard from android play shop, can help you solve the standby problem.
clouds5, did you ever find a permanent solution better than to turn on location services when needed? Your op describes my situation perfectly (except with sgs ii, jb) and I now only tick on location services right before I fire up maps/navigation/etc. Makes a huge difference in the amount of standby time, but I'm looking for a more satisfying solution.

AudioMix Wakelock on Stock KitKat

Hi guys I have a N7 2013 on stock KRT16S, and my biggest wake lock is AudioMix.
I'm rooted, using Greenify, and I even have Google Search uninstalled. I am not using GEL. People suggested turning touch sounds off, and I tried that too, but it didn't work.
Tried doing a search, and it seems like there's a lot of people who're affected by it, but very few people talking about it. All the references I could find:
http://forum.xda-developers.com/showthread.php?t=2520406
http://m.imgur.com/s0P3sr2
http://www.reddit.com/r/Android/comments/1ra1x7/
"BTW, what is this AudioMix wakelock? Is this like Audiut2 on the Nexus 4? Keyboard sounds or any sounds = wakelock? I also find it odd that considering I use my phone on vibrate 98% of the time, that the on my Nexus 4 and older phones, the speaker turns on when I press any button my phone. I thought system sounds wouldn't turn on? Quite interesting. Even in silent mode, the speaker turns on. I know this because my Nexus 4 speaker used to crack everytime it would turn on. To me that's an unnecessary wakelock that should ONLY happen if you're not in silent or vibrate."
Found one post on XDA by someone that seems to have a bit of a clue.
http://forum.xda-developers.com/showthread.php?p=47663736 Post 1713.
"Yup, perfectly normal. AudioMix is the new wakelock for audio (previously was AudioOut_2, if I recall correctly) and PowerManagerService is just a kernel wakelock cause by apps syncing in the background. Mine ends up around 30 minutes after a whole day of usage."
If anyone has more ideas, please elaborate and help out.

My Nexus 7 has the same problem.
AudioMix wakelock and no deep sleep.
I checked my running apps and noticed that currents keeps an active AudioPlayerService.
After killing the process deep sleep is working again.
So atm the solution for my Nexus is to kill the process everytime i used currents.

It's still persistent on 4.4.1... wake time seems to have decreased by a bit, but still there.
Hey guys, I'm having the same problem here, using CM11 (11-20140107-NIGHTLY-i9300) on Galaxy S3, and I guess I figured out the problem.
I looked a bit on some forums and found out that unchecking the touch sounds may solve the problem.
I just disabled all the system sounds and verifying with Wakelock Detector realized the counts stopped.
The problem here seems to be stopped here, maybe I add some updates later.
PS: I'm a little bit sad about disabling the touch sound, I was liking it so much
PS2: Sorry if you didn't understood something I wrote, I'm live in Brazil and I don't pratice so much my English.
Hi
Maybe a clue here:
http://forum.xda-developers.com/showpost.php?p=49781738&postcount=55
Have a look to MusicFX and DSP Manager.
It seems to be one of the two options in sounds Settings/Music effect ..
i don't like having a DSP running all the time (an active module to process sound) so i disabled them !
Im on a Tmo S3 running OctOS. I noticed the Audiomix wakelock only goes up on my phone when there are notifications or the ringtone is on. It creates a separate instance for each. If I'm streaming music from Slacker, nothing. Poweramp...nothing. Just notifications and ringtones. What that means? I do not know.

Android 4.4 - Wi-Fi is intermittent, buffering, dropping connections on Nexus devices

Hey,
I've recently upgraded my Nexus 4, Nexus 7 and Nexus 10 all to Android 4.4 and as soon as I upgraded my Wi-Fi has been awful.
The Wi-Fi is incredibly unstable, steaming media has major buffering / intermittency issues, messages sent over instant messaging apps are sometimes instant and sometimes take 30+ seconds to send.
Skype is the most telling of the issues as it randomly loses connection and my notifications literally never come through...

I've tried Channels, 1, 2, 4, 6, 8, 10 and 11
I've also tried adding
Code:
gDataInactivityTimeout=200
to the WCNSS_qcom_cfg.ini file as found: http://forum.xda-developers.com/showthread.php?t=2300873
Wi-Fi is Always On, Wi-Fi Frequency is Auto or 2.4, Wi-Fi Optimization is Off.
The wireless / wifi works fine on other tablets, laptops and wireless devices just my nexus devices on 4.4
Anyone got any ideas?
I think this logcat has everything "confidential" replaced however if anyone does find something please tell me, I've replaced my email with xxxx.xxxx and my usernames with xxxx

MTU Value is at Auto (1492, which my ISP recommends) although I've tried alternative numbers but still no luck.
Try the WiFi Keep Alive app from the Playstore and select Always On.
I know you already have this setting picked but I had the same issue and this solved it for me.
Good luck.

I just installed three different versions of Wi-Fi Keep Alive, the first one has 3 normal options then like 5 workarounds.
I'm trying the normal mode at the moment, so far so good it hasn't disconnected me YET
I picked always on + first workaround.
It worked great and haven't changed it since. That's 3 weeks now and it hasn't dropped out once
Hope that helped you.

Thanks, I'll keep trying as on my Nexus 4 it is playing up with just always on, I'm trying the workarounds.
Anyone else got any suggestions?

[Q] Nexus 9 Randomly Powers Off

I have a weird issue with my nexus. About a week ago I was using it bed time with about 50% battery, put it down and woke up next day and battery was completely depleted. I was watching a flash video so I thought maybe Puffin running flash could cause this so I ignored it. (maybe it continued to run in the background)
Today however, I wrote up to find out my Nexus had turned off again over night without the battery being depleted. It's as if it decided to turn off on its own. I want doing anything fancy with it either. Was just browsing, put it on my desk, wake up next day and it was turned off.
Had anyone else got this issue? Or have an idea what might be wrong,?
It actually happened to me again last night. Is there a log file somewhere I can have a look at that does system crashes or something before I RMA it?

On the shield there is an auto shutdown feature where you can have the tablet shutdown after a given duration of inactivity.
I don't know if there is a similar setting on the Nexus 9 but it may be a possibility.

Dont think the Nexus has such option
My Nexus 9 has done this a few times. Last night I started a movie in bed, couldn't finish it, so I went to bed. I woke up and went to check my tablet and the double tap wouldn't wake it up. I had to hold the power button down for 30 seconds before It booted.
Ok, @ombadboy, could you please show a screen shot of settings/battery/Usage.
This should show a list of apps which are consuming your battery. From the one which most consumes it to the least.
Then just to make sure also post a screenshot of settings/apps/running.
From this we can see which apps have highest running priority, and are using too much RAM.

Samsung Galaxy S21 Battery Drain

I stumbled across the below sensor (BSS_InDisplaySensorHelper) being one of the culprits for higher than usual battery drain.
It appears to be the fingerprint sensor displaying on the AOD. To stop the battery drain set show icon when screen is off to never. This appears to drain the battery regardless if you use AOD or not. I'm assuming this would effect all devices across the galaxy s21 range, maybe others can confirm?
You can use gsam battery monitor to check if you have the same issue on your device. https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
Hope this helps others as it worked for me.

"Fingerprint always on" try turning off...
Or just don't use a lock at all.

Check to see if you have the same drain regardless if you use AOD or not. Possible sensor bug that needs to be corrected by Samsung with an update.

AOD probably is not be the issue. Other apks like Google play Services, Backup Transport, Framework and any other cloud apks will commonly run in the background with the screen off eating globs of power.
Worse, they're aren't always reported correctly ie another apk is actually the perp.

I've noticed the same. This wakelock has always been there. However aod off seems to improve battery drain.
Hi, I have the same problem here except the option to disactivate it is greyed out because of power saving (which means it's either no the cause of the problem or one of the many ways samsung is ****ing with the user with contradictory options)

I never have used the fingerprint sensor or screen lock on either of my Note 10+'s.
Not even tested it.
The amount of potential trouble it could cause is epic with nothing to gain.
Double tap on/off
If this is the cause the work around is simple, turn it off. I can almost guarentee you that isn't the only app running in the background though.
It may not be the worst offender.
Also keep in mind app usage is sometimes misreported by the phone.
I just bought my S21 (exynos) 1 week ago. One UI 4.0 installation was a clean one. My friend bought an S21 FE (exynos too) at the same time.
I have a battery drain problem. He has not. I know these are not the same phones but not so different though. He can get 7-8 hours of SOT but I can get 4-5 hours most.
Here's my latest graphs (in turkish but I'm sure you'll understand):
https://imgur.com/a/aG0gWoT
Is this a normal draining? I performed any tricks that I found in the internet. But nothing changes. Now I'm using BBS to get the issue but nothing is unordinary.
