The glitch is causing the Nexus 5's battery to drain more quickly than it should when wi-fi is activated in the OS's developer preview version.
There's no specific evidence that the issue is causing a delay in Lollipop's rollout, but Google employees have at least acknowledged it.
Well that's something
"Android Engineering is aware of an issue affecting Nexus 5 users running Android 5.0 which causes significant 'Miscellaneous' battery usage while WiFi is enabled," Google Android Open Source Project Senior Developer Programs Engineer Trevor Johns wrote in a thread about the bug.
"This appears to be caused by an abnormally high number of IRQ wakeup events," he added. "We are continuing to investigate this issue."
Users who haven't yet received the Lollipop upgrade they're waiting for may be frustrated with the delay, but in the end it's better for Google to make sure they're not making Android phones and tablets worse with new updates.
