I got the orb for my Nexus and ever since I used it my phone doesn't go into deep sleep. I opened BetterBatteryStat and I have something called WirelessChargerDetector at the top of my list of kernel wakelocks. Also when I look at CPU state it goes to 384MHz instead of deep sleep when I am not using my phone. Obviously, this has hurt my battery life pretty hard. If I reset my phone after taking it off the charger, it seems to not have the kernel wakelock.

Can anybody with the charging orb see if they have the same issue?

This happened to me once, I don't think it has anything to do with the orb, any wireless charger can trigger it. It seems to be a service added in 4.2.2 to help the phone figure out when it's on or off the charger.

I rebooted my phone after seeing this and it hasn't happened since over several charge cycles. I wonder if moving your phone on and off the charger frequently can trigger it, because that's the only thing I can think of that I've avoided doing since then.

This has happened to me multiple times using the orb charger. Kernel wakelock stay active and the phone never goes to deep sleep. I've been rebooting to fix the issue but gets rather annoying to do every few days.

Looks like I'm having the same issue after 4.2.2 update

The wakelock is caused by PowerManagerService.WirelessChargerDetector. The only way to fix the issue is by doing a reboot of the phone EVERY time you use the wireless charger. This obviously defeats the convenience of the charger.

The issue appears to have popped up with the 4.2.2 update. I found this post in /r/nexus4 complaining about the bug as well: http://en.reddit.com/r/nexus4/commen...argerdetector/ and there are some people reporting it on the Accessories thread: http://forum.xda-developers.com/show...k#post38075837

Hopefully someone can figure out the issue or Google releases an update soon (not likely). Until then I'm back to my wired charger

EDIT: Found a Google bug tracker for this. Please star it: https://code.google.com/p/android/is...etail?id=52034

I'll chime in that I too have this issue. It's pretty annoying.

AW: Wireless Charger Detector -- Orb
Is there a homebrew fix for this?

Just wanted to post here (instead of starting a new thread) about the latest update. 4.3 does NOT fix this issue. For the past two days I have charged my phone on the wireless charger and the wakelock eventually comes up just like in 4.2.x

Hopefully with the new Nexus 7 having wireless charger there will be more people charging wirelessly and more demand for Google to fix this annoying issue.

I can second that 4.3 does not fix the problem.

I know it would be inconvenient, but could tasker automatically reboot the phone once removed from the charger? I could live with this every morning when I grab it off the charger.

If I manually reboot when I pull it off the charger right away, I can get well over two days one the Nexus 4 now with 4.3

I would love a better home brew fix, knowing it will be a long time before a new update comes from google now.

Agreed, noticed the issue again today after my 4.3 update a couple of days ago, drained down to 50% after 7 hours rather than the more usual 70%. I use two different wireless chargers (the official orb and a different LG charger) and only notice the wakelock about once every two weeks. Bit annoying to keep an eye out for it and I try not to move my phone off and on the charger (which negates some of the utility of a wireless charger as others have noted above). A reboot usually fixes it. Bugtracker starred.
