[Q] Why won't the Nexus 4 'stay awake' when on the Orb?

I have the orb and also normally keep my screen on when charging. I have the option ticked in the Dev settings to always have the screen on when charging, but the phone will not stay lit when on the orb (and it is charging). Any thoughts as to why?
Thanks in advance.
4.2.2 completely stock, rooted.

an update:
It charged last night just fine. Daydream comes on (if set to charging or docked, as seen in many threads), so I know for a fact the phone knows it's in "charging mode". The daydream will display, but my ideal situation is to have the screen stay on (possibly with an app open, like DoubleTwist alarm clock) while charging. Any help is greatly appreciated.

The only thing I can think of is that the phone doesn't know to keep the screen on when wirelessly charging. Let me explain. I have a battery widget that shows when the phone is charging and whether or not it's on AC or USB power. Well, when my phone is on the orb, the widget doesn't show any charging source, but does show the charging animation... Sooo... Big guessing here, but maybe the always on setting hasn't been updated to include wireless charging. Hell, Google didn't even add a charging tone for wireless charging until 4.2.2, which too coincidently, came out the same time as the orb was released. Again, just a guess.

So the phone doesn't have the wireless charging mode associated with the 'stay awake'.
I have filed a bug. Any comments, stars or support is appreciated.

If you have root, there is a work-around.
Using a terminal emulator or ADB:
Code:
su
svc power stayon true

Thanks, this worked perfectly

Also works for GNex5
For those who are interested, this 'fix' also works with Google Nexus 5, running 4.4

Wireless Charger Detector -- Orb

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
EDIT: Found a Google bug tracker for this. Please star it: https://code.google.com/p/android/issues/detail?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.

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?

Placing n4 on charging orb doesn't play sound and doesn't turn on screen

When I place my n4 onto the orb, the screen does not light up and no sound is played as expected on 4.2.2
Because of the screen not coming on, daydream mode also doesn't turn on after the set time.
The expected behavior I have seen on a friend's n4 when they put it on their orb is for there to be a noise then the screen comes on. If you leave it on the orb then it goes into daydream mode after the screen timeout.
Anyone else have an issue where it doesn't do this or know of a fix?

Do you have a case on your phone? On larger cases, the distance between the phone and the charger is too much for it to work.

No case. Also, I forgot to mention that the phone does charge just fine on the orb. It just doesn't make the sound and turn on the display to eventually allow daydream to turn on.

Odd. I'm pretty sure that 4.2.2 update turned off the sound if the phone's charge is >90% or something...
I'm assuming you have daydream set up properly too? There are a few different options for when it should turn on.

Same behavior if battery is below 90%. I have daydream set to "either" but same issue is I set to charge or even dock .
Anyone else seeing this or just me? I may wipe the device to see if that helps but really don't want to.

yup, same thing happens to me. running 4.2.2
so I have two QI chargers - one is the LG WCP 700 and that one will light up the screen just like its plugged into the wall
the Orb charges for me just as you described. that tells me for sure that the phone recognizes this as something different
---------- Post added at 09:31 PM ---------- Previous post was at 09:30 PM ----------
actually this dock isn't perfect for me. if i don't put it on right, it will alternate between charging and not charging every 2 seconds, and this will actually light the screen up. doesn't happen often, but its really annoying when it does. fixes if you move it a bit.

Nexus 4 Wireless Charging Orb toggle charging problem

Anyone else experience this? Look at the battery meter widget in the upper right corner. It will go from green (not charging) to blue (charging).
When this happens if I unplug the orb and plug that same cable into the phone it charges normally. This is my second orb that has done this.

Nobody?

Sorry, not a single issue with my charging orb.

No issues here either. When looking at your batt icon in the status bar, does that change as well? Or does it continually say charging?

The stock battery icon changes too. It's just easier to spot the widget.

Your phone looks a bit low in the vid. Does the problem happen if you raise the phone up a bit on the orb? And is your N4 have a case or screen protector on the back? Unsure if there is a slippage problem or not.

I do not have the slipping problem and it happens even if I reposition the phone.

I gots nothin, sorry man. Not sure why.

no problem with my orb, and it charges through wood:
http://forum.xda-developers.com/showthread.php?t=2196541

Nice! I actually envisioned doing that exact thing!

Right now my phone is sitting there at 87%, says it's charging, yet the battery is going down. It is also very hot to the touch. This is my second orb though. I wonder if the problem is with the phone.

Mine sometimes does this, I will hear it toggling off and on and such. Seems to not work with the bumper on it. Makes it not fully contact.

Mine also does this where it will connect and disconnect in a loop constantly repeating. I think it had to do with how i was placing the phone as it doesnt happen anymore.

It's probably still happening and you don't realize it. On mine the positioning of the phone does not change anything.

Maybe the problem is your phone, not the orb. My orb works like magic, the phone does not heat up and it charges just as fast as when plugged with the cable. Also, I use a quite thick TPU case, without any issue.

Mine has done that before (toggle on and off), but it seems to be okay lately. Only issue is that it gets pretty warm and seems to charge ridiculously slow.

I am having this identical problem. I got both the Nexus 4 and the Orb replaced, and my new ones are doing the same exact thing. Usually turning off the phone and turning it back on fixes it for some reason, temporarily though.

Mine does the same thing. Almost every morning I wake up and it's at 90% or below. No slippage at all. A few times it has been almost dead. Sometimes it charges completely but rarely. Restarts don't really do anything either.

Apparently not a small issue. Happened to me as well, multiple times, on 2 separate orbs. Waiting for the refund on the first before I send back the second. Wondering at what point they say enough is enough and give me my money back. Battery Monitor Widget screenshots attached. From 5% to 95%, it was in the same place on the charger. No slippage. It is in a case, but it should still be consistent, I would think. The day before, the second screenshot, was abysmal. 30% in 8 hours. It boggles the mind.

How to make my screen turn off while Wireless charging?

At the night when I'm charging the phone, the wireless screen saver (or what ever it called) stays on.
and when I wake up my phone is a bit hot.
How do I turn it off only when I charge it wireless?
I own The S8
P.s;
Sorry for the bad English, It's not my 1st language, If I need to clear something I will try to do my best.

yes.
Is it the AOD that is on?
If so.. That is not the cause that your phone is a bit hot.
That you phone is a bit hot is because of the wireless charging and maybe not original charger which is not lowering the power if the phone is fully charged?

It's not the AOD that on, It's like a special screen saver when you charging (I already turned it off).
The charger is Original, I got it from the Samsung store.
Tyvm, for the help.

You don't need a screensaver. Where did you turn it of?

Go to settings - display. At the bottom is screen saver. Turn that off.

But that is not on with stock settings?

Schedule your always on display to only turn on during waking hours.

Settings-display-screensaver turn it off.

Wow, I had no idea (or forgot) there was such a screen saver...
But I have a similar need, as thread title says, to actually turn off the screen when I place it on wireless charger, so I'll post my current workarounds...
Maybe someone has a better idea...
E.g. I use "Sleep as Android" app to track my sleep over sonar, so from my bed I manually start tracking, lock the phone and place phone on the wireless charger at night, but as soon as I place it on charger, it turns on.
It will sometimes stay on even though the phone is "locked" (similar to how Camera app can work with phone locked) so I have to carefully turn it off manually by pressing power off key (it is Samsung's flat mini wireless charger model (made for S6), not the stand, so it gets slippery to do it from bed).
Currently, I'm using the "Gravity" app that has an option to turn off the screen when phone is placed on wireless charger... But that is an issue since I also have wireless charger in my car and I do NOT want to turn off my display (I use phone for navigation) when I place the phone on my wireless charger in my car...
Luckily, Gravity app has exclude list, so I have excluded maps software that I use in the car...
