Multiple Nexus 5 owners running the latest Developer Preview version of Android 5.0 Lollipop have complained about the battery draining bug while using the Wi-Fi feature on their smartphones. This is likely to be the reason the Lollipop factory images, and OTA updates for older Nexus devices are delayed.
According to multiple forum posts on the Android-Developer Preview site, Nexus 5 users say the battery level drops steadily when Wi-Fi is switched on.
The Android 5.0 Lollipop global roll-out was delayed until November 12 due to some bugs and problems, a report suggested on Wednesday. The Nexus 5 battery drain Wi-Fi bug could easily be the problem behind this delayed roll-out for the Android L update.
However, the problem is an important manner, especially since Google already stated the “Android Engineering is aware of an issue affection 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 abnormal high number of IRQ wake up events”. In the same time, they stated that the issue will be further investigated.
Soon after discovering and accepting the battery drain issue on the Nexus 5, Google released an announcement suggesting that the “issue has been fixed in the latest builds, and this bug is now considered resolved’.
Considering that Google confirmed the Wi-Fi battery drain is resolved, you can expect the Android 5.0 Lollipop global roll-out to begin any time now. Also, Google announced on Monday that Android L “begins to roll out today”. However, there are no certain details regarding which regions will be the first to get the well-awaited update.
Android 5.0 Lollipop update is expected to land first on Nexus 4, Nexus 5 and nexus 7 (2012 and 2013) and Nexus 10, apart from Google Play Edition smartphones. Android One smartphones can be expected to the next in line to receive the update.
