Google acknowledges Nexus 5 camera/CPU usage bug, a fix is on the way

Nexus 5 Review aa yt (8)

Some unfortunate Nexus 5 owners may have been experiencing a bug involving abnormally high CPU usage and battery drain, which turns out to be caused by applications running in the background continually trying to access the handset’s camera application. Investigation into the problem has noted that Skype, in particular, “seems to access the camera regularly from its background service in some way that triggers this bug”, although the bug isn’t a problem with Skype or other third party apps.

The issue had been noticed by Nexus 5 owners (and on a few other devices too) once they updated their handsets to the latest Android 4.4.2, but fortunately Google is preparing a fix. The bug has been officially acknowledged on the Google Issue Tracking forum, and a fix has been promised for the battery drain, and other issues in the form of a maintenance update, which perhaps will appear as Android 4.4.3.

If you’re noticing battery issues and want to find out if your device is affected, you can check by heading on over to Settings > Battery and see if mm-qcamera-daemon is eating up your battery percentage. If you are affected, the only real solution at the moment is to simply reboot your device once you notice the battery draining. You could also try uninstalling third party apps which make use of your handset’s camera.

It’s worth noting that although Google was able to verify this issue on the Nexus 5, other handset owners who are noticing a similar bug shouldn’t rely on this upcoming update to fix the problem. Instead, Google suggests that other handset owners report the bug to their respective manufacturers, as an issue with their own software could be a cause of the issue.

For those affected, Android 4.4.3 can’t come soon enough.

    I think the battery is fine, but it could use improvement. This is a welcome change. Thanks and Happy BD google!!

    The only N5 issue i’m having is the constant need to clear data on maps to recover street names in the voice directions. But any update is a good update in my book.

  • If you got Skype problems I feel bad for you son. I got 99 problems but Skype ain’t one.

      How do you know that skype doesnt make problems in background?

      • I was saying that Skype is the problem. I would never use Skype so I don’t have that problem. Plus…. it was a joke:/

    Guessing it will fix other nexus devices with the problem as well

    Damn I figured something was heating my nexus 5 up at times (which led me to reboot) , glad to hear its not just my phone.

    It really eats batteries

    For me, Google Play Services has been the huge battery drain. Received a replacement phone due to the original having GPS/wireless charging issues. The first day, the new phone battery life was great. A few days later, the new phone is having 19% (20 minutes) of Keep Awake for Google Play Services (15 minutes of GPS), with the NlpCollectorWakeLock using 16 minutes of time. And I already disabled Google Search and disabled Location Services Reporting.

    But I have noticed the camera bug once or twice on my original Nexus 5. Glad to hear a fix will be coming out for that.

      Indeed Google services contribute in a large part to battery drain. It’s pretty essential to ensure the three settings are configured as such:

      Location Reporting = OFF
      Location History = OFF
      Google Now = OFF

      And BAM. Suddenly the OS only consumes about 14% of battery life when the phone is idle – leaving the lion’s share of battery drain to Cellular and WiFi – as it should be.

    They acknowledge this camera bug but don’t acknowledge the video recording issue that the nexus 5 has shame=/

  • AussieGreek

    Crap non removable battery, crap camera, really scrappy speaker, no sd card but it’s a great phone because it’s a nexus!!!

  • Karl Rowley

    If battery life is an issue, get the Moto G. I get 2-3 days of battery life even with a lot of yackety-yak. I don’t have LTE and blah blah blah, but I’ll take battery life over these features.

    • gommer strike

      But that’s probably because you really don’t do a lot of other things with the phone other than just using it as a phone, which doesn’t drain a whole lot of battery. What’s your screen uptime in those 2-3 days?

      I can get 5 days on one charge with my HTC One.
