I've had my N4 and LG WCP-700 wireless charger since Nov. Every night I have charged my phone while streaming Scanner Radio Pro via Bluetooth without issues. For the past 3 -4 nights I've noticed that at some point while sleeping my screen turns on and my phone stops charging. I wake up in the morning to my phone screen on and battery draining. I'm just wondering if anyone else has had the same problem and/or can recommend an app that can maybe find what the heck is causing my screen to fully wake and not turn back off?
Thanks!
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/comments/1988qm/powermanagerservicewirelesschargerdetector/ and there are some people reporting it on the Accessories thread: http://forum.xda-developers.com/showthread.php?p=38075837&highlight=wakelock#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

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.

It should be able to but you would have to set a second activation point. Remember that when the battery gets full chargers will "stop" charging the phone. Qi chargers do this too so as soon as the battery tops off and it stops charging Tasker will consider this as an actuation point for the reboot and do so. Essentially you would end up with endless reboots until you take it out of the charger in the morning.

Yeah it's not very fun. What is interesting is that the New Nexus 7 doesn't have this issue. At least not so far, I've been testing it since I got it and there have been no wakelocks. This either means that the issue is only with the Nexus 4 or the newer build fixes this issue... So I wonder if using build JSS15J on the N4 would fix this problem...
EDIT: Nope, JSS15J still has the problem I wonder why the New Nexus 7 does not though...

Could a software solution be the answer? Maybe someone could write an app (or even a tasker profile) to somehow kill the wirelesschargerdetector service with a button or when it stops charging?

Maybe but then that same software will also use up some battery as well to monitor the wakelock.
The issue hasn't been acknowledged on the AOSP bug report (star it here if you haven't yet). So I started a thread on the Google Products Forums, reply to it and lets see if Google will at least say something there:
https://productforums.google.com/forum/#!category-topic/mobile/android-devices/other-google-products/c4HRzEUNmFk
Also seeing this problem. Didn't have it in Android 4.2.2, but DO have it in 4.3
Happens to me on Nexus 4 and Nexus 7 (2013), both on 4.3.
Anyone know the command to kill the PowerManagerService.WirelessChargerDetector service via Terminal Emulator? This would save us from rebooting.

Did you try to plugin USB charger for a second ? For me, it removes the wakelock and no need to reboot anymore.
Update: I was wrong, wakelock reappear soon again....
I've written a small app to try to fix this problem.
It needs root access.
I haven't tested it much yet but I think it should work.
All it does is kill the qualcomm sensors daemon when you lift the phone off the charger.
This lets the wireless charger detection service release it's wakelock because the gravity sensor starts working again when the daemon restarts.
Open the app once and click the button, it will ask for root permission. After this, you never need to open the app again.
Let me know if this works.
you could set Tasker to reboot when unplugged from the charger...right?....because with wireless charging it still acts as if plugged in when charging...
Thanks for the app. Will try it out.
I have been starting to wonder if something else is going on. One I have started using the wireless charger and even with a reboot noticed a ton of wake locks and a noticeable difference in battery life.
Anyone else seeing this?
My 6P on 6.0.1 stock with the march update has had occasional times where it will intermittently charge, then stop, then charge endlessly, changing back and forth about once a second or more often. There's been times I've woken up, like today overnight when I noticed it barely inched up a percent or two on the Google USB-C cable connected to my laptop.
To isolate this from being a defective cable issue, this has also happened with the Google charger that came with the phone. I would see the screen turn on in fact, like when you first plug the phone with the screen off, to indicate charging has begun. That would occur every few seconds.
I'm a little concerned. The time it happened with the charger, a reboot seemed to have calmed it down. But today no matter the restart, the charging just keeps cycling nonstop.
Anyone else had this? Would it be wise to file a problem with the Google forums and contact support?
Thanks for any help!
Same problem here
Dang, good to know I'm not alone!
I've also experienced higher battery drain (twice more I'd say) than normal recently. Even overnight when I used to see hourly drain rates of 0.5%, now I see 1.5% and higher. Getting worried the charging issue may be damaging the battery. But it could also be the patch or a rogue app.
I have the same issue - it started about 3 days ago
Well either the cords bad, the brick is bad, or the receptacle. Or the charging port on the phone, the battery or power control module in the phone. Or if theirs a thick case on your phone.
Sounds like it starts to charge then stops. But I'm no electrician. Oh wait, yes I am.
It starts to charge, then stops as though the cable was disconnected, then resumes within half a second, then disconnects, and so on and so forth non stop.
Case might be a reason. It's a rubber and plastic transparent Spigen one. I'll try removing it when it happens again next time.
But at this rate, sounds like 3 people are having the same issue, and if it's a hardware one, then damn....
This isn't the charger... There is something buggy with the update. I woke up a few days ago after the march update with an almost dead phone, and the charging icon flashing over the battery, as if the phone new it was plugged in but refused to charge. I unplugged and plugged it back in with the same result. I restarted and tried again, same result. I was only able to get it to charge my plugging it into my girlfriend's nexus 5x charger, which instantly started charging my phone. I went back to my charger and all of the sudden no issue and the phone was charging fine. There is definitely something up with this update.
Well then, that makes 4 people now.
What's a good way to report this?
I'm not seeing the same exact issue as you guys, but I AM having charging issues after updating to MHC19I. I can still charge my phone from the stock charger and my other USB-C chargers, but now none of them allow my phone to charge rapidly. Do you guys who can get your devices to charge from a rapid charge compatible charger see the "Charging Rapidly" message on the lock screen? Ever since this recent update, I've noticed that my device isn't (and is taking over 2 hours to charge fully from ~20%).
I have this problem too. It's fixed by a reboot so I'm assuming it's not a hardware problem. It only happens once a week or so.
The first time it happened I didn't notice the charging/not charging and only realised something weird had happened because my phone was off & showing fully charged. My phone is never switched off.
I figured it out the next time when I noticed the screen was still on during the night. Switching from charging to not charging was keeping the screen on.
So glad it's not just me.

I normally see it say that on the USB C charger. That being said, you seem to have an intermediate speed going on, as opposed to super slow normal USB cable speeds and the USB-C fast charger. In my experience most 1-1.5V low amp ports like my Mac's, or the car's USB port will charge at a rate of about 1% per 3-5 minutes. So a full charge would take 8-9 hours from 0%. From the USB-C wall charger it would be about 1%/m so an hour and forty is enough to get it back to full.
Based on that your charger seems to be somewhere in the middle.
But yes it isn't normal. If you are using Google's native hardware, you should see the same charging speed as I am.
I'm just terribly worried this cycling is destroying my battery. I have definitely not gotten the same battery life the last few weeks.
Hey guys!
I experience sort of the same problem as you guys, but i have the Nexus 5x
i copy from my thread at google nexus forum
My phone just randomly die. It will work for like 2 hours. Almost like the battery would been disconnected.
When the phone shutdowns it says the battery is low and try to charge. The Battery icon with a flash is showing, but just for 5-7 seconds, then it shutdown again and it's looping again and again and again.... To get out of the loop i'm booting in to fast boot, then push at start. and it is almost 50/50 if it is working. It can be booting up and you see the red/yellow/green/blue yada yada boot-up sequence then in 5-7 seconds in to the sequence it would shutdown again immediately.
I tried several factory-resets. re-flashed to stock. Nothing helps.

Same issue
Just starting having this issue. It constantly says charging then a second later shows no charging and the process keeps repeating itself. I did a reset and the issue seems to be resolved for now. Really hope this isn't a constant issue. Definitely appears to be software related though.

I hadn't had it for a while then recently it happened again once. I still don't know what triggers it for sure.
The battery drain is also rather random. There are days I can expect the unit to idle and drain at or below 2%/h, but lately it just goes through it way faster, twice that. I am unsure why and how that happens so randomly. Seems the Google Play Services and Google Apps are using up some %s. Not much else I can identify.
I've had this issue since a few days ago, restarted the phone and it's come right for now.
Haven't experienced this in weeks now.
Seems largely gone.
Any updates on this? My Nexus 6P started showing the same symptoms (either won't charge at all, or charging cycles on and off rapidly (< 1 second) and only sometimes charges). The issue appeared out of the blue 4-5 days ago, just before the 1 year anniversary of receiving the phone. I tried different cables and adapters, still no change. Last night at 11pm it was at 50% when I set it to charge and it seemed to charge. This morning at 6:30 am it had only charged up to 83% and was charging on and off. Worried about how to reliably use the phone if it won't charge, and also how this might affect the battery / other circuitry.
Any help/tips appreciated!
Edit: The phone hasn't been dropped or had any other issue that may affect the hardware. Also, no OS update or anything recently (AFAIK - it did not ask me to install anything, not sure if there were any silent updates). It is currently on Android 7.0 Nougat (baseband version angler-03.72, build NBD90X, security patch level Oct 5, 2016).
Have not had this in a long time. It sort of stopped on its own. :S
Solved (for me anyways)
I just had to restart the device.
I'm having the same issue on my LG G5. Started out of the blue and like others, restarting temporarily solves the problem. Anyone solve this yet?
Hi guys,
Recently I've noticed that while charging my phone, sometimes it charges normally (that is 2h14mins to full), but sometimes it changes randomly to some weird 4 hours or so. Estimated charge time changes during one charge randomly. I am on nougat 228, using original charger that came with the phone, plugged to a wall, not using the phone during charging. Also, I have heard about this battery calibration method, can it fix this issue? Not sure whether nougat update could have caused it.
PS: The phone is new, like a week old.
My phone has got the same problem, also if phone is turned off it will take a long to charge, did you find a solution?
So anyone facing an issue like where when I connect the charger, phone wouldn't start charging? It just stays idle as if nothing happned. Then I gotta use it somewhat so the battery percentage drops atleast a percent or two and then when I plug it, it starts charging like normal. Its happened second time today, I thought it was just a weird bug the first time it happend 2 days ago. But now I am worried since it has recurred.
PS - charger and socket are fine I checked them.
Any help would be appreciated thanks
