5 Battery Drain Giving You A Headache? Google Is Releasing A Fix Soon
Google
has acknowledged the battery drain issue in the Nexus 5 and is about to release
a fix for it soon. The company claims the drain is due to high CPU usage of the
‘mm-q camera-daemon’ process, which allows other apps to access the camera of
the phone.
Once
started, the process remains in the background, even if the app has been
closed, thus consuming more power than it would otherwise. The Android Open
Source Project (AOSP) code discussion is buzzing with complaints about the
issue. “Issue 60058: mm-q camera-daemon cpu usage” has quite a lot of posts
from developers and users who have faced the battery drain and there are quite
a few solutions too, though we cannot vouch for how well they will work on all
devices.
Explaining
the issue, AOSP member Eino-Ville Talvala said, “We believe we have fixes for
the current high CPU reports on N5 (Nexus 5) due to mm-q camera-daemon, and
they will be included in the next maintenance update.”
While
there’s no estimate for when the fix will arrive, Talvala said that until it
arrives “rebooting the phone is the only way to stop the high CPU usage/lack of
camera function once it starts.” He also touched upon the latest update for the
Skype app, which seems to have exacerbated the issue. While Talvala says that
Skype itself has no bug, the app seems to “access the camera regularly from its
background service in some way that triggers this bug”
“Other
camera-using applications may trigger this bug as well, but that’s been
relatively rare. Most applications also do not access the camera when not in
the foreground, so they will only trigger issues when actively used,” he added.
Some
users were complaining of this issue even when using other phones that have
Qualcomm processors. For this Talvala said, “Instances of high CPU use of mm-q camera-daemon
on other devices besides the N5 (Nexus 5) need to be reported to their
manufacturers. While those devices also use a Qualcomm chip for their camera processing
(and thus have a mm-q camera-daemon process), each has differences in their
software and issues with them do not necessarily mean the N5 has the same
problem, and vice versa.”
Hopefully,
all manufacturers will take note of Google’s word and roll out a fix for the
issue as soon as it’s added by Google.
