A battery draining WiFi wake-up bug could be what’s causing delays with the rollout of Android 5.0 Lollipop for the Nexus 5 and other devices. The bug was discovered — and now confirmed — in the latest Android L Developer Preview, as posted on the Google bug tracker page. Scrolling through the page, you’ll find countless users reporting Nexus 5’s that have been impacted with the bug and, at least for now, the Android team seems to be stumped on what’s causing it. Googler Trevor Johns did chime in on the issue saying,
“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. This appears to be caused by an abnormally high number of IRQ wakeup events. We are continuing to investigate this issue.”
So while it’s not confirmed that this battery draining WiFi bug is what’s causing the delayed rollout of Lollipop for the Nexus 5 and other devices, we’re sure Google wants to release things with as little bugs as possible. We’ll let you know if we hear more.
UPDATE: Annnnnnnnnd…. it’s been fixed.
