The bug that threatened to delay the Android 5.0 Lollipop update for Nexus 5 was already fixed early Thursday, reports said.

Those who received the preview version of Android 5.0 Lollipop in their Nexus 5 devices pestered Google with numerous complaints, saying that their batteries drain more quickly when Wi-Fi is enabled.  This bug was confirmed by Android senior developer programs engineer Trevor Johns, who gave an explanation on the Android Developer Preview website.

He said, "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."

Nexus users were not expecting to see a battery-draining bug from Android 5.0 Lollipop, since one of the reported features of this operating system software is the battery-saving mode that automatically slows down the device's CPU and shuts down the background data once the battery reaches a critically low level.

Then on Nov. 5, Johns announced that they already managed to fix the problem.

"This issue has been fixed in the latest builds, and this issue is now considered resolved. Thanks everyone," he posted.

Because of the bug fixes, several sources shared to Android Police correspondent Artem Russakovskii that the release of over-the-air Android 5.0 Lollipop update will not happen until Nov. 12 after Google initially reported with a Twitter post that the updates will come soon.

"Hey guys, I just got word from one of our tipsters that the first OTAs got delayed due to some outstanding bugs, now currently scheduled for the 12th," Russakovskii said.

If the battery bug had been fixed already, it means that the much-awaited Android 5.0 Lollipop operating system update for Nexus 5 devices, as well as the updates for Nexus 4, Nexus 7, and Nexus 10 will roll out very soon.
