[Q] Did the Nexus 5 and/or KitKat fix the wireless charging wakelock? - Nexus 5 Q&A, Help & Troubleshooting

So I currently have a Nexus 4, and I'm waiting for my new Nexus 5 to be shipped to me so I can give the Nexus 4 to my wife.
I have two LG WCP-300 wireless chargers for my N4 and about 80% of the time you take it off the charging pad a wakelock keeps the CPU from going in to deep sleep. I then have to reboot the phone.
Does the Nexus 5 still do this?
If it is fixed, did KitKat fix the issue (i.e. will the N4 be fixed too) or is there some sort of hardware change in the N5 that fixed it?
Thanks!

I think the short answer is "no", but here's the long answer...
I've never had the wakelock issue that causes the phone to drain like crazy after it's been removed from a wireless charger, but the problem I do have is the wakelock keeps the phone from sleeping while it's on the charger. So my phone fully charges in a couple of hours when I go to bed, but by the time I grab it in the morning the battery has drained to 75 or 80%. Luckily I haven't had the issue where this continues to be a problem throughout the day.
I upgraded to KitKat yesterday (from factory image, without a wipe), but I had the same problem overnight. I kind of doubt it will help, but I'm considering wiping my phone to see if that will fix the issue. I'm hoping that whatever bug it was in 4.3 got fixed, but my lack of a wipe let it creep into 4.4. Unlikely, I know, but I can hope. Sorry for the bad news.

No wakelocks with wireless charging on my N5 to date, but I've only been through a couple of cycles since I got it on Friday. How often does it occur with your N4?

Yea, Google fixed the issue. I had it bad with the Nexus 4, but charging the Nexus 5 using the same Orb I have absolutely no issues.

haven't experienced this wakelock issue myself yet. Just got my wireless charger yest and works fine.

I had the wakelock problem with my N4 but have had no issue with my N5

I have zero wake locks with the N5 since launch day. Wireless charging I use every day. No issues ever.

OK - I've started using my Nexus 5 full-time and I'm using the wireless charger - a LG WCP-300, which should be high enough quality to be a "reliable" charger for the N4/N5. I'll report back if I have the same issue I had with 4.3 and the N4, as the results here seem to be mixed.

same problem here with nexus 4 and no change after updating to 4.4
the problem is 2 part
1) fast drain if the phone is left on the carger when fully charged
(if removed when full it will discharge much more slowly)
2) charging never restarts no matter how low the battery goes unless the power to the charger is interrupted
or the phone is removed from the charger and replaced.
forcing a reboot with tasker does not restart charging
I put the charger on an outlet timer that turns it off for 1 minute at 6am.
that restarts the charging so I can wake up with a nearly full charge.
this works. if you set the timer for 1-3 hours before your normal wakeup
time you're gonna have a nearly full charge when you get up because most
of the time the charger will not turn off for quite awhile after 100 charge is reached
and it will stay at 100% until the charger turns off (charger light turns to green from blue).
there may be other chargers that don't have the same problem.
mine is the round flat charger you see on ebay that comes with different color rings for about $22

I'm using the same charger, but I don't think this is charger specific. My girlfriend's S3 (which I think is on 4.2.1) charges perfectly with several different wireless chargers using an add-on wireless charging receiver.
Clever solution, btw. But it would be great if this would just work the way it's supposed to. :-/

[Q] Battery Staying at 100%

I've noticed that the battery meter will sometimes stay at 100% for a while and then all of the sudden drop to the actual percentage sometime later. A reboot after unplugging the phone will fix the problem and report the battery % at the correct level. I was wondering how many other people were experiencing this, or if it is just a hit or miss thing?
I'm still on stock, unrooted, no mods. It's a straight out of the box Skyrocket.
Also, does the problem remain after rooting, modding, etc.?
I asked this on the battery results thread in general, and only received one response, so I figured this would be better in Q&A.
I had the same issue, but it has only happened one or two times.
Showed 100% for hours then rebooted and it showed 73%
I don't know how long you've had your phone, but it takes several cycles from full to empty for the battery to calibrate correctly. During that time you can get some really funky readings on it.
I am experiencing the same problem.
I've also had a hard time charging the phone. I've left it plugged in upwards of 18 hours, only to find it saying its only 83% charged. That may just be another symptom of the same problem though.
Do you think this is a phone or a battery issue?

That sounds like you were plugged into a pc vs ac power and had heavy usage during that time.
Mine charges very quickly when at idle and plugged into the wall.
I've had my phone since the day it launched (the 6th) and just experienced this for the first time yesterday. It was indeed quite odd to see.
I have had this happen one time. I also noticed the phone got very hot.
It actually happend yesterday, stayed at 100% almost all day then just shut off and wouldnt reboot.... freaked me out!!

I think that the battery is pretty wonky. I am not sure if the NFC addition is causing these issues but some people are having amazing life ans some people (me included) get horrible. I am getting a warranty exchange on my battery. No way I should drop 12% in an hour and 20 minutes when the only usage is 19 minutes of checking email. If I have to have it plugged in every time I turn around it is not exactly a wireless device now is it?

Strange, I was just reading this thread and thinking I have never experienced this. Then I checked my battery stat and it showed 100% even though I've been using it for an hour and a half. I restarted and now reads 90%.
Had my phone for almost a month. Rooted only on stock ROM. Just took it off USB cable from laptop an hour and a half ago.

I think we narrowed it down to being a bad charging circuit in the phone or battery triggered by a .1a charger.
When we got our new skyrockets they stopped doing it.

I was powering my phone off, plugging the power in and allowing it to recharge. The phone would automatically power on as soon as I connected the power but I didn't think that mattered. It turns out it did. If I powered the phone on and then connected the power, the battery meter would work correctly.
This was different the Captivate I had previously. That phone had the capability to charge while powered off. There was even a charging graphic that displayed while the phone was off.
The Skyrocket did not have this same feature when I originally bought it. However, ATT did an update at some point and now it does. I've been unable to re-create the stuck battery gauge since that update.
please only use the charger that came with the phone. other chargers, after prolonged usage, may cause issues.
The charger that came with most skyrockets is a .1a charger and causes the issue as well. A few reported getting .7a chargers in the box but most have been .1
I have tested the iPhone charger theory on 5 phones now. Phone 1 and 2 experienced the issue. Phones 3-5 did not
Its more than just the charger. The phones experiencing this either have a bad battery or it's in the phone

From day 1 with the skyrocket, I have used an old wall charger and cable and had this problem daily. I plug it in at night and in the morning, it's at 100% until I reboot, or some other random event that drops the percentage to the real battery stats.
Because of this thread, I dug out the box and used the wall charger and cable that came with it, and this morning shortly after unplugging the phone, it was at 99% and dropping, just as it should. Very glad I tried this.
Ummm no.....

I did a recheck of my black cube SR wall charger (Samsung part # ETA0U80JBE).. It is NOT .1a it is 1.0amps - which - interestingly enough is EXACTLY what my iPhone3g power cube right next to it delivers.
The .7am Samsung charger has the usb connector on the side, and is part number ETA0U60JBE - delivering 5v at .7 amps (30% decrease over the little cube device). That was the charger my SGS-II had. My S/R came with the 1.0 amp ETA0U80JBE version.
One amp will charge the phone MUCH faster than the USB port. Per the spec, the typical USB device cannot drain more than 500mA (1/2 of what the power cube supplies to the phone).
Unfortunately Apple and Samsung both have the cubes pretty well locked up, so I cant compare the components, but at a first glace they appear to be absolutely identical, both putting out about 5.1 volts at zero load.

charging issues jelly bean

well is it only me having charging issues with jelly bean? a quick search in google proved that a lot of people with other phones when they updated to jelly bean have charging issues (very slow charging, even on power u cant work tablet even in power save mode it stills droping!
anyway couldnt find anything here fore note 10.1! so what about you guys?? i had to go back to ics cause of that
with or without JB you will have the charging issue its not an issue but because of the huge battery note has

ofc its a rom issue as when i go back to ics the charging its ok! in jelly bean its very slow! i mean i put on charge all night and only about 20% charged! its not hardware problem, but jb issue. i just dont see anyone else here with note 10.1 complaining about this.
Don't have that problem, Only goit 3hours sleep last night and plugged in note before going to bed. Fully charged from 46% in 3 hours.... You might have a problem with your charger/cable/charging port....
If you have an S2,S3 or Note 2, or an old Gtab, the charger works for your note so you can check where the problem is....
Only charging issue I have is when I use different charger other than the original one then its slow..if I use the original one its fast

The OEM charger supplies 2 Amp hours of current to the battery. If the battery takes any more than 3.5 hours to charge the 7Ahr battery then there is something wrong with the tab or the charger.

Note takes around 5 hours to do a recharge, but if you have extention USB cable of a after market USB connector for longer length it will increase the charging time
Max charging time for me with OEM is about 3.5 hours with power saving mode on and screen off, or around 2.5-3 with the tablet OFF. Thats with a 6-9% battery remaining. Anything much more means something is eating your battery in the background while you are charging.. make sure you use OEM charger.
my charger was slow charging right from the box. They gave me a new one the next day and everything is fine now.
Thats odd. I never had any charging problems when i upgraded to jellybean. Have you compared your unit with someone who also has a note 10.1?
I picked mine up on Thursday and charged it to 100% with the supplied charger and cable, installed the 4.1 system update and used it throughout the following day watching video and general playing. I had it plugged in whilst I was using it and noticed it discharging, odd I thought as it should at least have maintained its charge but after my battery level dropped to 19% on that evening I turned it off completely and left it overnight, this morning it had only charged a further 20%. It has to be a firmware issue as its the only thing thats changed since I first charged it fully without any issues (first charge on 4.0 took approx 3 hours from unboxing).
I also have the same problem. Any solution to this?
I also want a solution to this.
I'm at wits end and feel like smashing this thing.

No. Its still doesn't charge faster. Same result.
Its going back to Samsung today.
That sounds screwy... I have mine on all the time, plug into the wall and about 3 - 5 hours later its fully charged...
Might be the wall charger is the problem, Samsung may have a batch of faulty chargers....
Doubt its the charger. Because its now 100% full but still says charging, not charged like on 4.0.4.
Even my battery stats don't reset anymore.
In my opinion something happened in this OTA. Been viewing many 10.1 forums for a while now and never read anything about charging issues. Since the update, its an issue unless all of us just happened to either have faulty chargers at the same time or we all downloaded the same app at the same time which is the source of the issue. Im gonna say its not neither of those because what did happen, is we all downloaded an OTA at the same time and have since had this issue.
One thing I have noticed that works a little better for me is to do a reboot right before I throw it o the charger. I dont unlock it or anything, just keep it on the charger.
Im thinking of rooting over the weekend and trying a few different ROMs to see what happens.

Just a thought, but lots of people are complaining about this and lots of people are not experiencing a slow charge.
The update has been rolled out in many countries now - so what country are you all in and what sort of mains power do you have? Maybe it's something related to that
Shouldn't matter as the charger is the one in charge of voltage to the Note.
You can use a charger from America in Australia, UK or Europe (with an adaptor of course) and it should charge your note the same everywhere.
I have tested this by using a stepdown transformer to charge my note at 110 volts as well as the normal 240volts we use here in Australia. No difference.
I have an overseas model Note and need an adaptor to connect to the Oz mains. I also have another note bought here in Australia and it works fine using either Australian or overseas charger too at either 110V or 240V...

[Q] Qi Wireless Charging and Overheating [TYLT VU Specific]

I purchased the Tylt Vu wireless charger for my N5 and N7. Last night, before I went to bed, I charged the N7. In the middle of the night, I switched out the N7 and charged the N5. When I woke up this morning, the phone was too hot to touch, and had been powered down (as designed, based on the heat). It took about 5 minutes before the phone was cool enough to power on.
A couple questions: Can such extreme (??) heat do permanent damage to the phone? Has anyone else had this problem with the Tylt Vu wireless charger? The phone wasn't off-center, and nothing appeared abnormal when I set it on the charger. I wonder if transitioning from the N7 to the N5 so quickly caused an abnormality?
[UPDATE (2/17):]
I haven't been following this thread, as I decided after my overheating incident to no longer use the Tylt Vu with my Nexus 5. I was also a bit turned off by the response I received from Tylt.
I take no credit for the following information, I am only summarizing this thread to save you time.
The Tylt Vu is defective. It contains three charging coils that help it to charge any device without having to be finicky about positioning. However, unless you set the Nexus 5 onto the Tylt Vu in a specific manner, the third (top) coil will remain activated, resulting in overheating due to the magnets present in the Nexus 5. (Oversimplified explanation... read the chain for specifics.)
The "right way" is to set the Nexus 5 down in the crevice of the Vu, perpendicular to the earth, and then pivot it down to rest on the back of the Vu. The wrong way is to slide it down the back, or otherwise set it on the Vu in a way where it is not touching the short base first. (See post #118.) You can also permanently disable the third coil by opening up the Tylt. All of this applies to charging the N5 in portrait mode.
A big thanks to NCguy for his persistence throughout the thread, to Mr. Sprinkles for his theory and relentless testing, to jelledgeu2 for the "solution", and every other poster who has shed some light on this. And a big 'no thanks' to Tylt for their response to the issue.
tl;dr: Always be vigilant on how you set the N5 on the Tylt Vu, or charge the N5 on the Tylt Vu at your own risk.
I have a Vu shipping now, I will report my experiences. Both of my boys have nexus 7's and will watch those too. Tyvm for the heads up...

Were you able to successfully charge it before and this just happened the night when you switched from N7 to N5 ?. I don't think overheating damages any electronics because it is designed to shut off.

I can confirm that I have experienced this with the same set up (n5+TYLT VU), although I also have the Spiegen Slim Armour. This happened though only once, when I was at work and the phone was baked like a hot potato!
Since then I have been coy about leaving it on the charger unattended - I have checked the phone regularly since,. both after and during long charges - the problem has not happened again.

Thanks for the heads up, as I am looking at purchasign the Tylt Vu.
The only thing I can say is that heat can definitely cause degredation of the battery. Besides that, there should be no signicant damage to the phone.
Thanks, everyone. I was able to charge both the N5 and N7 twice before without any troubles. I'm a little skeptical about leaving anything on it to charge unattended now -- my N5 was untouchably hot this morning. I've emailed Tylt to ask if they have any background/information on what could cause this to happen. I'll let you know if I hear back.

yes! I bought 2 tylt vu's from kickstarter and experienced exactly the same overheating problem. It was overnight and there was no charge on the battery in the morning with it still at 54% and very hot. It's possible that that the phone may have become mis-aligned on the charger but its unlikely. I just didn't happen to notice before I grabbed it off the charger. I can't explain how it happened and its only happened once....... so far.
In general the phone is alarming warm even when its working. The battery temp is usually around 110+ F even after it finishes charging. This compares with a battery temp of around 80F with the USB charger.
I'm not an expert but I'm thinking that the battery heat is not being generated by the battery itself internally but possibly by a heat transfer as a result of the induction. If that is in fact the case then maybe the warmer battery isn't as bad as it would be if it were in fact generated internally in the battery as is typically the result of a high charge/discharge rate.
So my concerns are two fold, the one-time completely unacceptable high overheating and the ongoing situation where it is always 20-40 degrees higher while on the tylt than it would be plugged into the USB charger.
I wouldn't be too concerned except that replacing a battery in an N5 is not like replacing a battery in a phone with a removable battery.
Wow... I wasn't expecting two people to have had identical experiences. Slightly concerning, however, it sounds like it's only happened once for each of you (NCguy, Drizwaldo1). I hesitantly charged my N5 again on it tonight. I watched it closely and pulled it off when it hit 100%. No problems, and only moderately warm (as is typical for wireless charging). I would chalk this morning's incident up to a fluke and forget about it if the phone hadn't been so insanely (explosively!?!) hot this morning...
I have a tylt but I have not tried it yet on the N5. I use a Nokia qi charger primarily and have not had an issue. Only have the phone since the 8th. I just got a spigen case. Let's see how that works out.

Are you guys at all concerned about premature battery wear with the battery temp 20-30 degrees higher than the usb charger? That's when its working "normally" and with a tylt.

I'm not overly concerned about it, primarily because I get a new phone almost every year and expect the stock battery to be sufficient for at least that amount of time even with degradation. Worst case scenario, it doesn't sound like it would be hard to swap it out (based on iFixit's assessment). I'm more worried about doing irreversible damage to the internal components if it overheats again like it did on the Tylt.

My Nexus 4 got a lot warmer on the Qi charger than my N5 does, and it's battery showed no ill effects. So no, I'm not worried about my N5.
I just purchases the Vu charger as well to pair with my Nexus 5 and 7. I hope the overheating thing isn't common... I'm a bit worried.
Please continue reporting. I'll do the same once I receive my Vu.
Wow, thanks for the Headsup!
I was quite close to buying the Tylt vu despite the very high price tag.
Hope not all qi chargers have this issue.

I hope you're right. I'll probably go for it also. Hopefully I won't have to do an ifixit battery replacement but it doesn't look too awfully bad if it comes to that. I keep them a year but then usually pass on to my wife who would rather not be leading edge. I probably should give it to her with a decent battery. Unfortunately non-removable batteries s##k.
Found a post on another forum about the N4 doing the same thing (got so hot it shut off, never charged), he said resetting the phone cured it. Sounds like a software glitch to me.
any new updates or issues that has occurred? I have my tylt coming in a few days and wondering if I should just return it for the DT-900.

[Q] Nexus 5 INSANELY Hot to the Touch When Wireless Charging

I'm wondering if anyone else has run into this or has any ideas as to what may be happening...
I've been charging my Nexus 5 wirelessly at home and at work with my TYLT VU wireless charger. The N5 is listed as compatible on the Tylt website, so I don't think that is the issue. It has been charging successfully overnight since I got the phone about 3 weeks ago. However, for the last two days, I wake up to find the phone has stopped charging at 80% and 84% yesterday and today, respectively. Also, the phone is INSANELY hot to the touch, to the point that it is unsafe to hold. I have to set it aside to cool for a few minutes before I can handle it.
Yesterday, I thought it was a one time glitch, and that I hadn't placed the phone properly in the charger. But last night I was careful to lay it in the charger so the green light activated. No improvement, same result.
Notes:
- The phone is in a Spigen case
- I do NOT have Developer Options enabled
- Stock Android, locked, unrooted
- YES, the screen times out after about 2 minutes (does NOT stay awake)
Any ideas? I'm really worried about the phone getting this hot and not charging.

I've been charging my Nexus 5 wirelessly at home and at work with my TYLT VU wireless charger. The N5 is listed as compatible on the Tylt website, so I don't think that is the issue. It has been charging successfully overnight since I got the phone about 3 weeks ago. However, for the last two days, I wake up to find the phone has stopped charging at 80% and 84% yesterday and today, respectively. Also, the phone is INSANELY hot to the touch, to the point that it is unsafe to hold. I have to set it aside to cool for a few minutes before I can handle it.
Yesterday, I thought it was a one time glitch, and that I hadn't placed the phone properly in the charger. But last night I was careful to lay it in the charger so the green light activated. No improvement, same result.
Notes:
- The phone is in a Spigen case
- I do NOT have Developer Options enabled
- Stock Android, locked, unrooted
- YES, the screen times out after about 2 minutes (does NOT stay awake)
Any ideas? I'm really worried about the phone getting this hot and not charging.

its probably your charger. mine gets warm but nothing insane. i charge during the day in my cube and typically have a full charge when i leave, and it lasts all night till i get back to work. so i basically sit by my charging phone all day and its never really caused me any concern. i have a knock off "qi compatible" charger from ebay. works great for $20
Holy s*it that thing is expensive. Sounds like there is a process that is getting triggered by charging and running the cpu to 100%. Think about a new app installed since heating started. Ordered 2 of these with no odd heating of device.
Off topic: What would developer options being enabled or disabled have to do with wireless charging? (just wondering)
good day.
Have you tried it out of the case? Maybe it's not vented properly in it

I saw several comments about this very thing in a qi charging thread after the phone started to ship and they all used that charger. Most said it ended up being a one or two time thing but the charge you mention was common to all the situations. I suggest getting better battery stats from XDA and then check it after charging. Also try charging in short half and hour to one hour time frames until you know it is not truth so hot.

Mine doesn't get noticeably warmer charging on the Nokia Qi plate than it does over USB. Maybe you should contact Tylt.

Developer Options is where the "stay awake while charging" setting is. I just wanted to make it clear that I didn't have that setting enabled. That's all.

Thanks for this info... I will try it out and see what happens.
Thanks for all of the help everyone, hopefully this was just a random incident. It's charging fine now at work: on the VU, in the case, at 100%, no overheat. Weird. I'll try it again overnight tonight and see what happens.
Or maybe the case causes the heat because of the added distance between the charge pad and the coils in the phone? Dunno if that's possible tho? Lol

There's something about that Tylt Vu charger that sometimes doesn't recognize when the phone is fully charged and go into trickle-charge mode, as it should. (Although I've never heard a conclusive answer as to why the battery is usually found at a low charge percentage, so there may be another reason.) There are numerous reports of overheating with that specific charger. It doesn't happen all the time, and in fact, many people report that it works fine for weeks, then one day it does this, then works fine for weeks again. Still, it's a VERY common problem with that charger, and it only takes one time overheating to damage your battery.
I'd contact the manufacturer and see what they'll do about it (refund, working on a fix, etc.). In the meantime, you could try the Nokia DT-910. It's a similar stand-up type charger, and doesn't seem to suffer from the same problem.

Come join our club. If you're lucky, it only happens once.

Glad I'm not alone. Thanks for the link.
I realize this thread is old but this happened to me last night. I woke up this morning to my Nexus 5 shut off (it was turned on when I placed it on the charger) on the Tylt Vu charger and when I picked the phone up I couldn't hold it comfortably. It physically hurt to hold my finger on the screen. I have never felt a phone that hot before. I would imagine it shut down due to heat but shutting it down didn't stop it from continuing to charge in some sort of error state.
I am done with wireless charging. I am actually curious what would have happened if I had left it all day. I truly believe I'd have ruined my phone or started a fire.

Hot after overnight charge (not wireless)

HI everyone, for the second day I noticed that after I left my N5 to charge overnight it was fairly hot after I took it off the charger. I have been leaving it to charge overnight for months and normally its not even warm since it trickle chargers after hitting 100%. My Nexus was charging right next to it and it was cool when I took that off the charger. It did fully charge and I checked if the phone was maybe not sleeping the entire night but that wasn't the case either. I checked with Current Widget and it was showing that even at 100% it was still taking around 200 mAh power. Usually it shows very minimal charge at 100%. Has this happened to anyone? I know I've read this happening with wireless chargers where it the phone wouldn't even charge, but in this case the phone was charged and it was just using the stock charger.
It also seems like I'm getting the Android OS bug after taking it off the charger. I suppose this might the cause of the entire thing. I'm just worried that it happened two days in a row.
The phone continues charging passed 100%. First it will still show 450mA eventually dropping to 200mA or so as you saw. Eventually true 100% is reached and the battery starts draining 0-10mA while the AC provides the rest.

Thanks, that's what should happen. But it seemed the past two nights it never dropped to 0-10 mah. Which is why I think it was hot in the morning. I just charged it from about 70% to 100% and it did trickle charge this time, so hopefully the issue is solved now. Has this happened to anyone though?
