Android 5.0 Lollipop Update Problems on Nexus 5: Experiences Battery Drain Bug
Google announced the release of their latest mobile software, Android Lollipop, Monday and has been rolling out the update to its Nexus phone line, notably the Nexus 4, Nexus 5, Nexus 7, and Nexus 10. However, it seems that the OS has hit a snag with the other Nexus devices and users are reporting issues of increased battery drain.
The drain is apparently caused by a Wi-Fi bug as reported by users. The problem was discussed over at the official Android Developer Forum, where the thread is now over 800 posts long. Android Senior Developer Trevor Johns joined in on the forum and confirmed the presence of the bug.
"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," Johns wrote.
The senior developer's confirmation that the team is aware of the problem suggests that Google does not have a fix for the bug yet. The battery drain is completely significant as John's post suggests where Nexus 5 users are reporting that a fully charged battery lasts only four hours or less.
A quick fix can be achieved by turning off Wi-Fi but considering the mass roll-out of the update to Nexus 5 devices, it's hardly considered as a practical solution to the problem.
Google is yet to see if the bug affects other Nexus devices, considering that the Nexus 6 and the Nexus 9 are seemingly unaffected – with both devices coming out of the box with Android 5.0.
The presence of the bug might also be the cause why the update is still to roll out on the other Nexus devices.
