Latest Developer Preview version of Android 5.0 appears to come with battery draining bug (Fixed)

Latest Developer Preview version of Android 5.0 appears to come with battery draining bug (Fixed)
Android 5.0 is the latest build of Google's open source OS. Unfortunately, Lollipop has a bug that is sucking battery life right out of Nexus 5 models that are running the latest Developer Preview version of the Android build. The problem has turned up on the Android-Developer Preview site as a number of Nexus 5 owners are complaining about their battery level dropping precipitously when Wi-Fi is enabled.

An abnormally high number of IRQ wake up events has appeared with this issue. This deals with waking a handset back up after it powers down, and is possibly a clue for Google to look at in determining what is causing the problem. Google has not said whether or not the battery problem is behind the delayed rollout of Android 5.0 to the Nexus 5 and other models.


Certainly this is not an issue that Google wants a large number of consumers to deal with. And that means patience for those looking forward to receiving the update for their Android device.

UPDATE: Trevor Johns, the Google Software Engineer quoted above, has now posted a message on the Android-Developer Preview site that reads, "This issue has been fixed in the latest builds, and this issue is now considered resolved. Thanks everyone."

So there it is folks. You can stop worrying about installing Android 5.0 only to find your battery sucked dry while on a Wi-Fi connection. Now get to sleep!

I have the Preview on my Nexus 5 Some days I get ~4 hours SOT Other days I get ~3 hour SOT with Miscellaneous using 20% of my battery Seems promising though, once Google fix the issues with Miscellaneous and once devs update their apps to take advantage of Project Volta

I was hoping for a qqcameradaemon Fix for my n5 with the lollipop update and now this? I will not update if this remains an issue.

It happens, I wouldn't shoot google on a dev build. If it was a release build like their chrome for laptops or other various 4.3 and 4.4 bugs customers had to deal with then yea, it would be a problem. Like the infamous camera bug that kept it running even when it was off. Hopefully I will get a taste of the L in a few days when we install it on a few test devices.

Almost all releases have this big at first. That is why there are 4 updates for kk

Also its a Dev Preview, which means its basically still a Beta OS and not meant for users

Guess I must have been lucky, had neither issue. I am not denying they existed or exist for others.

That's why in my opinion it's always better to wait for developers or even OEM to iron out the bugs than jumping right in *ex Nexus User

Not that it had much battery life anyways.

No way am I updating my Note 4 when this eventually arrives for us as I bet the 1st 5.0 builds for OEMs will also have this stupid bug. Thanks but not thanks! :) I'm getting incredible batt life on 4.4.4, with around 6-7hours SOT, no way am I giving that up for an update.

True. Same with my Z3 Compact, not gonna update to L even if Sony releases it without the guarantee of debugged patch.

I stopped connecting to Wifi on the preview as I was seeing a high amount of wake-ups via the battery stats. I thought it was because I forgot to turn off "Scanning always available" under Advanced Wi-Fi.
