Multiple
Nexus 5 owners running the latest Developer Preview
version
of Android 5.0 Lollipop have reported a battery draining bug while on
Wi-Fi, and this is thought to be the reason for the
delayed
roll-out of the Lollipop factory images and OTA updates for older Nexus
devices.
Reporting the bug on the Android-Developer Preview site, Nexus 5 users say the battery level drops steadily when Wi-Fi is
switched on.
Notably, the Android 5.0 Lollipop global roll-out was delayed till November 12 due to some 'outstanding bugs', a report
suggested on Wednesday. The Nexus 5's battery drain Wi-Fi bug could be
the reported 'outstanding bug' that caused the roll-out of the latest
version to be delayed.
Google, without wasting much time,
acknowledged the battery drain issue. Google's Project member Trevor
Johns said on Google bug tracker page, "Android Engineering is aware of an issue
affecting Nexus 5 users running Android 5.0 which causes significant
"Miscellaneous" battery usage while Wi-Fi is enabled. This appears to be
caused by an abnormally high number of IRQ wakeup events. We are
continuing to investigate this issue."
One of the users reported, "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."
Another
user who tried to use his Nexus 5 without Wi-Fi shared his experience
and noted, "This might help. I tried a whole day without Wi-Fi 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."
Both users were referring to the battery use menu, which
listed Miscellaneous as the primary consumer of battery life, something
that is ordinarily not the case.
Soon after acknowledging the
battery drain issue on the Nexus 5, Trevor Johns added, "This issue has been fixed in the latest builds, and this issue is
now considered resolved. Thanks everyone." The Google bug tracker page
titled "miscellaneous in battery stats" now notes "Fixed" as status
pointing that the issue has been resolved.
Considering that Google
has now claimed the Wi-Fi battery drain issue has been resolved, and
that it is already rolled out to the 'latest builds', we can expect the
Android 5.0 Lollipop global roll-out to begin soon.
Google on
Monday announced
Android 5.0 Lollipop "begins to roll out today". The company did not
provide details on which regions will be the first to get the update.
However, the Android 5.0 Lollipop update would be rolled out first to
the Nexus 4, Nexus 5 and Nexus 7 (2012 and 2013), and Nexus 10, apart
from Google Play Edition devices. Android One smartphones can be
expected to be next in line to receive the update.
