Severe overheating while on charger - Samsung Gear S2

Has anyone else experienced severe overheating while on the charger?
I Have had my Gear S2 4G for about a week now with no issues and has been working very well. I usually set it on the charger overnight and have never had an issue until this morning. Reached over to put my watch on and it was VERY hot, not just warm. It also only had 60% of a charge. It also displayed the overheat warning message. I powered it off and let it cool off, then placed it on the charger again. It's currently charging fine again and is at a normal room temperature while being on the charger for the last 15 mins.
What would cause such a serious overheat? This is the 1st time it has done this. Anyway I'm gonna monitor it and post again here if it happens again.

Maybe an app was misbehaving. Did you install anything new recently?

I was looking in to that. I did install a couple different apps earlier so I am monitoring them to see if they were the culprit.

[Q] Random Shutdown Issues - Bad Battery?

Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!

[Q] Battery temp too low and not charging

Hi All,
I have this problem of the tab not charging,
Was searching all week and had no luck. Seems like a common problem among phones especially on SGS and SGS2.
When it was on , it showed a message saying charging paused Battery temp too hot or cold.
Now the battery is drained, and when charged to the mains, it would show a yellow triangle, and a thermometer.
See picture attached..

Just wondering if anybody had any luck figuring out why this is happening and any work around?
Just to rule things out, Tab had not been in any wet places...
service manual
I was going through the service manual and it was saying,
"If the battery will no longer charge, completely you need to replace it with a new battery. Take you device to your local service centre.."
Thoughts?..

Well first if you still got factory warrenty...
get it fixed by samsung...
If you want to save a few dollars you could attempt to pry the screen out from the back cover and charge the battery externally then if thats a NO GO buy another battery online and then put it back together.
Ive read before with charging problems that if teh battery gets completely Flat it wont have enough charge in it to activate the charging circuits.eg when you plug in charger you get black secreen and no battery icon,you need to pop the screen out and remove the battery and charge it from a external source.then replace it.
Never seen anything about your particular problem though...
I will enquire to Samsung, not expecting much because, tab7.7 was never officially launched in Aust.
Ho do you go about charging, externally?

Try plug in wall charger for 30 mins then hold power button for 15 seconds.This is good for waking it out of deep sleep and getting it to trigger charge.
another thing is possible fix from factory reset in twrp?
i would try a few things like this and leave opening it up as a last resort.
for your info google how to open up galaxy tablet and you can find pics
how to prise the screen out of the back cover.ive bought tools for this but havent done it yet as worried about damadging screen or cracking it.
there are clips around it and you have to pop the clips out.
Australia samsung probly wont fix it as not australian model..
another thing to ry is charge using ipad 2ma charger...
Experienced exactly the same issue in May 2013. It was functioning well and charging without problem all along and suddenly turned out like this. Tried different method to have it charged but no luck. I have to bring it back to the service center for repair finally.

Did the Samsung guys tried to explain anything about this?
What did they replace? Did they just replace a battery?
Please let me know.

Galaxy GT-N5110 Note 8.0 - Charging paused...battery temperature too low...
I purchased a Galaxy Note 8.0 (GT-N5110) last July. It's been working great until yesterday when a window popped up stating "Charging paused. Battery temperature too low."
I tried shutting the Note down and charge the battery whilst turned off. It seems to be charging just fine at the moment. Will check it in a few hours when the battery has been fully charged.
I installed an app called Battery Monitor Widget. It's reporting that the battery temp is around -2c to -4c while charging.
UPDATE: Battery is charged @ 100% and the Note is still on AC power. Battery Monitor is reporting that the battery is -3.7c then to -5.9c...
My next test is to completely drain the battery and see about charging then.... Will keep you posted...
Can't post screenshots for now...
Skol!

UPDATE: Now on battery, the battery temperature is reporting at -4.7c...
I some how fixed it by accident..
First I thought it was a faulty battery only to realise that replacing the battery did not work...
Next I followed one of the remedies I read where it said to connect the charger to the unit with the wall charger connected and connect the battery (there is a ribbon cable).
Some how it worked. Started charging etc.
I noticed that the battery had full charge as I had it plugged in for a whole night before when i was experiencing the TEMP too low symptoms.
It seemed as if it was charging all along but was showing that stupid error on the surface...
Hope this helps some people.

Have this issue with one of my S4's (fortunately I have a couple so can swap things about)
The phones had a life of luxury on my desk, except it suddenly started reporting 'battery temperature too low' issue and not charging
The same battery in another S4 is absolutely fine, so the battery itself is ruled out (and indeed 2 other batteries will not charge in the unit having problems, despite working fine in other S4's)
It seems that something has died in the S4 itself internally. and is likely going to require replacement/fix at a service centre.
How many other people have this? - it could be an issue with the device build.

[Q] Did the Nexus 5 and/or KitKat fix the wireless charging wakelock?

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

see updated post below
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] 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.

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.

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?
