mm-qcamera-daemon battery drain

Destroying my battery life. Never had this before but recently my battery has been utter crap because of this. Always have had the same setup with every ROM I've had with Franco kernel. But this is ridiculous; at this time by 1pm I'd usually have 85-90% but I'm already at 68%. Anyone else have this?

Looks like an issue with Yahoo! Messenger's voice/video plugin
Have you tried uninstalling it or configuring it?
Or do you have any other third party apps that use the camera?

It happened to me multiple times, this is caused by an app using the camera wich crash. For me it was Snapchat, it told me that it could not access the camera so I stopped the app but some hours after I saw that this "mm-qcamera-daemon" killed my battery. After a reboot everything was ok : Snapchat working correctly and no drain.
I think that if you get an app saying that the camera is not accessible, immediately reboot your phone.

it also shows up every time you take hdr photos

Seems like it's snapchat guys. It wasn't able to access camera. Reboot fixed it temporarily but this is annoying as I notice it happens a lot now. Thanks for the info.

Yes. I have this issue, since a few days, too.
There is maybe a bug or something. I found a thread where lot's of people reporting the same issue: http://code.google.com/p/android/issues/detail?id=60058
In another Thread here, I found some solution possibilities like uninstalling Google Goggles. But it didn't help me.
So if anyone founds a solution how to (manually) fix it, please report. Not using the Phone and have a battery drain of about 50% in ~5h is annoying.
Maybe someone can make an app that detects which app is causing this problem or which can kill the process!?
€dit:
I have neither snpachat nor Yahoo Messanger installed

Google just announced a fix for this bug. Android Central: Google pinpoints Nexus 5 camera/CPU usage bug, fix coming in next Android release. http://google.com/newsstand/s/CBIwzPD-ihI
If this post helped you, feel free to click "Thanks"... Thanks!

I've had my phone ever since 4.4, this only started happening recently. Instagram is always at the top of the list now. I used to get 4-6 SOT now I only get 1-2 hours. Anyone else having this annoying problem?

I sometimes get it, a restart fixes it. Though it can be annoying because you won't notice that it's doing it until you realize your battery is going down faster than normal.

Pretty sure it's been the last few updates since it happened on my n4 too before the n5 came out.

Do you use the camera inside Instagram? If so, then stop using it.
Try clearing cache/data of instagram and reinstall it after a reboot.

The problem is that when a camera app like the one that allows users to click pictures or Skype is used, it continues to run in the background and uses CPU cycles. This not only leads to the battery drain but the phone also heats up.
Instagram uses the camera.

I am experiencing the same problem.

It doesn't seem that the latest update to Instagram has helped things.

Battery drain from a non-running app?

Hi. Its been a few days since my Nexus 5 battery has been drained pretty fast. Lasts only about 4 hours after fully charged with little use. Since I recently started working in a really poor reception area I figured that was the problem, my phone constantly trying to find a signal, but when I go to the details, I see that Instagram is responsible for using up 40% and it wasnt even running!
Im no developer, or even experiencied android user, but, how is this possible?

Welcome to android and app permissions. It's accessing a number of things on your phone with location probably being the number one. Get something like xposed and app ops to tame what the app is allowed to access. You should also get gsam or BBS to get a closer look at what is using your batery.

This happened to me last night with a messaging app I used to replace hangouts. It dropped about 12% overnight with data and WiFi all off.
I looked in battery use and messaging sucked most if it up. I cleared data in the messaging app and that fixed it. Later today I switched back to hangouts until I download another messaging app. I don't trust that one now.

Thanks for your reply. I'm guessing I need root for Xposed and those other apps ? Like I said I'm just an ex iPhone user who just converted to Android. So haven't given myself the time to tweak around.

you dont need xposed. looks like instagram had a stuck process or was stuck syncing. a reboot usually fixes that. there are other ways to fix things, other than installing xposed(as xposed could bring in its own issues). there are many apps out there that help, greenify being one of them. also, there are a few great apps to help you stop wakelocks that are out of control.

[HELP] Problem with wakelocks on Pie Stable

Hello everyone.
I have a huge wakelock problem runningatest stock pie + flashkernel + xXx 2.9.5
Below you can see the huge amounts of wake-ups in a low period of time. Tried to disable some Google services and the wakelocks are still present.
Can anyone recommend me anything? Please as I really wanna get rid of them.
For any questions please ask, or if you want me to provide anything else besides this screenshot. Much appreciated

Those are normal, really. It's not killing your battery like you think they are. You would have to get rid of google entirely to demolish most wakelocks.

That's perfectly fine. If you try to block more wakelocks blindly you might end up causing more battery drains in the long run cause it keeps trying. It's very similar to my BBS stats.
I can tell you almost everything Google related (which most are) there's not much you can do about it except maybe check account sync section, untick Google's "features" for its apps, or get rid of it entirely.
The second one is because you were on a phone call.

how do I find the app behind the wakelock ?

currently my S20FE 5G is running a rooted stock based custom rom that has a few OneUI 4 elements in it somewhere, no idea what those actually are.
I'm getting some steep battery drain but otherwise I'm quite happy with the rom and want to keep it.
I've got a partial wakelock called VK_WakeLock, it's keeping the phone from sleeping when the screen is off. I searched for a while and can't find a method that would help me find the app that's causing it or even better the specific service or process.
if we know the name of a wakelock is there any terminal commands or apps that could lead me to a package / process name ?

What's accessing the internet when that happens?

I have background data off, I have a firewall that keeps the majority of apps without internet. most of my user apps (which aren't involved) don't do background stuff, so basically I've got no idea right now.

Try temporarily disabling Google play Services at night. It's a blood sucker, day and night.

it hasn't been a battery drain for me previously, if it was an update that brought this effect the internet would be full of posts regarding it. as it stands their are only a handful of search results for VK_WakeLock.

Well you know how I feel about updates...
You can try making sure all system apps are updated or roll them back to their factory load versions.
Clear system cache. Clear system app caches or data.
Find the root cause. You need to ID that apk responsible for your mystery name.
or
Factory reset and hope that gets it.
This is why I don't update. Cleaning up an update mess is time consuming.
