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.

i use the nexus orb charger at work and the LG 700 charger at home. While the phone can get a little warm, I certainly wouldn't consider it hot.
I'm not sure why your charger didn't turn off when reaching 100%

It never charged. The phone was at 70% when I put it on the charger. When I woke up, once I was finally able to boot it up, it was at 73%. It was scary hot.

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.

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.

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.
Last night I charged my new nexus 5 with the charger my wife always uses with her galaxy s3. I noticed the charging icon turned on (lightning symbol) before putting the phone under the pillow.
I woke up this morning realizing the phone is extremely hot and it seemed like it hadn't been charged at all.
I charged the nexus 5 again with its original charger and everything wad just fine.
Anyone has this problem before? Will the extreme heat damage the phone or the battery at all?
Thank you

Absolutly... and do not use other wall chargers I would say. Especially if you haven't tested it with your phone yet.
But... that still sounds strange imo, it obviously should be hot while charging under a pillow, but why would it be discharged and still hot way after the normal end of the charging ? I'm thinking of a black screen of death i'm afraid..
Happened in the past with my optimus 2x until i got a kernel which fixes it.
And so, exactly the same situation was happening sometime before the fix ; put on charge during the night and in the morning, got a very hot powered off phone with an empty battery despite beeing still pluged...
Just my 2 cents

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.

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. :-/
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.

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.

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.

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.

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.

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.
Since there’s a fair amount of posts that note this, particularly with this charger, I figured I’d start a poll. If you have a TYLT Vu, have you run into the overheating issue/does your Nexus get uncomfortably hot while charging?
FWIW, I have two Vus and have not had this issue, at least not yet. While the phone does get warm, it’s not hot and I would consider this to be expected. I also happen to keep the phone in this case: http://www.maxboostpower.com/shop/m...stand-fits-all-versions-of-google-lg-nexus-5/.
UPDATE: While I have not yet tried this, an XDA member has some steps for reproducing the issue consistently, and subsequently how to potentially avoid it, at http://forum.xda-developers.com/showpost.php?p=49282197&postcount=119.
UPDATE: Lastly, we have acknowledgement from TYLT on the issue and how to work around it—maybe they’ll become a responsible company one day and actually fix the problem one. From http://forum.xda-developers.com/showpost.php?p=49467213&postcount=157:
Hi ****,
Thank you for contacting TYLT customer support. We actually found a solution for this issue, when you place your phone on the VU put the bottom part of the phone onto the base of the VU at an angle so the screen is tilted towards the ground a bit then put the back part of the phone onto the VU. This way the middle coil will be activated which is a perfect match for the coil inside your phone.
Please let me know if this solves the issue.
Thank you!
Thanks,

My tylt charger is causing my Nexus 5 to overheat. It gets above 50 degrees when I charge in portrait mode. I have read in forums that your company is working on a fix. I just want to be put on the list to have mine replaced once it has been addressed.

Cheers.
I haven't had the issue with mine.
I've had one of these for just over a month and I leave my phone in it to charge every night. I also use it regularly as a stand when I'm at my desk.
The phone does get warm while charging, but no warmer than it did when plugged into the stock charger.
It takes about 3 hours for my phone to charge from <10% to 100% (about 30%/h).
How to you define overheating? I have two TYLT and the N5 tends to get warmer by a few °C compared to other Qi chargers. However, it depends very much on the actual battery status (SOC, temperature) prior to starting a charge.
I have also noticed that turning off Day Dream reduces temperature rise during wireless charging by about 3-5 °C in average.

I’d guess I’d simply describe is as uncomfortably hot. While I haven’t experienced the issue myself, the people who have tend to describe it this way. I’ll make the OP a little clearer.
I have three wireless chargers, the Nexus charger, Tylt Vu and an older WPC-700. Same issue with all three, sometimes they're slightly warm, other times they're hot. No rhyme or reason as far as I can tell.
Welp, add me to the list. Just pulled my N5 off the tylt and the back near the camera was almost hot enough to burn me. Charge stopped at 85%. It's become pretty warm in the past, but nothing like this. Very alarming.
Can't help but wonder if it has something to do with the metal discs in the N5 and the multiple coils in the tylt... It's like putting a steel pan on an induction cook top.
No heat with mine. I leave my phone on it all the time. At least every night, sometimes during the day as well. It is never warmer than when charging with the standard USB charger. Same goes for my Nexus 7.
I have a one and I've noticed the N5 getting very hot but only if I leave the screen on and slightly hot during Day Dream so now I just make sure the screen is off and everything is okay.
I DEFINITELY feel it get warm... haven't noticed it coinciding with screen being on for periods of time, but my screen WAS on last time it got super hot...
Mine overheated once overnight. In the morning the N5 was so hot I couldn't hold it in my hands.

My N5 has also gotten very hot numerous times, too hot in my opinion when using the tylt. Doesn't happen every time though. I've tried to determine if it has anything to do with placement, but have not been able to tell. I also have a Google Nexus wireless charger and the phone never gets hot when charging. I'm now trying the phone on it's side on the tylt and will see if it continues to overheat.
I had my Nexus 5 overheat once when I pulled my Nexus 4 off the charger and place my N5 on immediately after. Woke up in the morning and the phone was off and HOT. No issues since but I never charge one phone right after the other.

Happened again! The back of my phone measured a little over 130F. Starting to think something has gone wrong with my VU. I've owned it for a month and haven't had a problem, now suddenly it's attempted to deep fry my poor N5 twice in the last week.
Emailed TYLT about this, but not confident I'll ever get a response. Seems like they've been ignoring emails lately.
My N5 overheated (to the point it stopped charging) every day on my Tylt for 4 days until I disabled Daydream, now it hasn't happened since.
That said, looking at Battery Monitor Widget tells me it's still charging too warm (40-46c) just not warm enough to trigger an overheat warning. Daydream probably just pushes it over the edge.
My guess is this is a fairly common problem with the Tylt and the N5 due to the metal disks the N5 has for magnetic alignment - something I'm not aware of many, if any, other Qi compatible phones possessing. The Tylt has 3 coils and a 1amp charger which lets it charge faster than other Qi chargers but probably pushes the envelope in the process.
Could vary between models, I guess, but I wonder how many N5 users with Tylts who also use Daydream (or otherwise have the screen on when charging) have this issue?
Also I've read that charging in landscape helps - slightly more airflow around the back of the phone, and less of the metal disks come in contact with the coils I bet are the reasons.
PS: I have the stock Nexus Qi charger (the new one) on my dresser and a Nokia N910 at my office and have no problem with either of those - and temps stay in the 30c range. Both of those are also single-coil chargers powered by 500mA US and charge slower than the Tylt as a result.
Welp. Unfortunately, it looks like I can be added to the list of those who have been "burned" by the Tylt Vu. I've been using two different ones for about two weeks now with no issues at all. The hottest my N5 would ever get would be around 37C (but it would usually hover around 34-35C). I've been keeping an eye on the battery temp since reading all these horror stories of overheating. Tonight, it was charging fine when I picked my phone up to check a text and mess around for a couple minutes. When I put it back on, it was probably around 37-38C or so. I was sitting next to it and touched the screen to check the temp, and it felt REALLY hot (only about 5-10 minutes after setting the phone back down to charge). So I took it off and the battery temp was showing 49.5C with "health" saying "overheating". I always make sure the screen is turned off after putting it on the charger, so I know it wasn't in daydream or anything. Kinda freaked me out. I love these chargers, but my faith in leaving them unattended while charging is now shaky at best.

I have a cheap Chinese QI charger for 21$ single coil its charging faster than the wall adapter AC i plugged it into a Asus Nexus 7 2Amp charger and it doesn't overheat at all i think this overheating has to do with the Tylt having 3 Coils instead of One
I've never used an app to look at internal temperatures. Do any of them have an alarm that would sound if the temperature went over a certain mark?
Mine was hot several times when an app was running in the background. Since then I've made sure that all apps and antennas/radios, and the screen is/are off. I have two vu. Same problem.

You can use tasker and have the phone ring on battery overheating condition but to my knowledge not a specific battery temp. It's kind of too late but at least the phone won't sit there and continue to cook.

The screen can be completely out when this happens. It runs a bit hotter during normal charging with Daydream but its definitely not the cause of the overheating condition.

BTW, for the record mine has overheated twice in excess of 132 F and stopped charging at around 70%
