Overheating while charging - Nook Color General

Last night I had my NC down to about 70% and was going to let it charge for the overnight. While it was plugged in, I was watching streaming video from justin.tv before going to sleep and noticed that the corner area to the right of the n was getting very hot. The NC is in an Aegis case so the temperature had to have been pretty high to feel it though the silicone. I immediately unplugged and after letting it cool a few minutes replugged it and this time it didn't exhibit the same overheat. The battery seems to be working normally right now.
Is this a common occurance? I shudder to think what would have happened if I fell asleep while this was going on (it was sitting on the bed) and woke up to the house on fire.

I have some overheating at this area too, maybe it's just where the processor is..

Same here. Is that a known issue, or is it just a normal thing with the Nook Color?
I got mine launch day, if it makes a difference.

Just to add that this NC only about 2 weeks old and it was the first time I ever noticed the battery getting that hot.

Battery does not charge

So friday I noticed that the time would lag. sometimes 20 minutes, sometimes 2 hours behind, a soft reset put it back in normal time. Weird. Today I went to grab it to go to work as it had been charging all night long with a steady green light. I open it up and there is a red icon for the battery...23%..... I hook it back up to the AC adapter and see what it does, it shows a plug to symbolize charging and I check it 30 minutes later, it has dropped to 20%. My bluetooth is off. I now have it hooked up to the AC adapter and removed the battery, i have the battery on a charging dock and the TyTn II has a faint red LED where the normal area for the charging LED is. I am gonna see whats happening in an hour with the battery...
Has this bricked?
Time lags and battery does load now. Its only been in use for 9 months, never been dropped.

I love how people never think the battery is going bad and always think it's the phone right off the bat.
Try another battery and see what happens. Hopefully you bought it new and still have the warranty on it.
Okaaaaaaaaaay....I do not lack in the technical department. The battery charges on the dock and I got it up to 100%. I loaded it back in the TyTn and let it sit for 3-4 hours and it dropped to 90%. I hooked up the AC Charger to it and I got the steady light up on top like it normally charged before all this. The battery continued to drain. I now have it powered completely off and using my old KRZR....(smartphone to cell phone....wonderful) I have a new battery on the way for a week now so it should arrive shortly.
Some wiring leading from the Mini-usb to the actual battery must be corroded or something. I cant explain it...I do live by the sea, and if the contacts are not gold plated in there...I can see some problems occurring. I doubt the warranty would still be intact as I have upgraded the ROM to Win 6.1

Thanks Garfield....I knew there had to be some sort of explanation....

Does your phone get hot charging USB?

Please, I'd like to see feedback from people on what circumstances people are seeing their phone get hot charging USB. If your phone gets hot on a USB charge, try powering down the phone completely and then charge on USB, does it still get hot?
And please, if your phone gets hot on USB charge, post how you're charging, your ROM, and how hot does it get? There are many applications for this. I use Battery Snap, you can use any program you like. If you don't have a program, please don't guess at the poll, but feel free to post results in a reply.
Also one would assume ambient temperature in the room is typical, but if yours is not (<20c, >28c) please post that information too.
Please answer the poll by the typical range of temperature your phone gets on a USB charge. I'd suggest charging around the 50-60% mark to get more consistent results.. For example charging if the phone is at 95% wouldn't be useful information etc..
One more slight constraint; if your phone gets hot "one time" but not other times, I'm inclined to think there was something else going on with the phone at that time. If your phone is consistently hot when charging USB then post results here.
Reserved in case I need to add any info..
I charged my phone off my Dell M6400's docking station today, started the charge after pulling the phone out of my horizontal case and the phone was 29.5C, I looked multiple times at the highest I saw it was 31.3, and most of the time 31.1. Using Battery Snap for the data. Started charge at 80%, as that's what charge it was from this morning until 4pm when I started I do not have USB Debug enabled by default on my phone, nor did I have mass storage.. When I got the mount prompt I just hit the back button.
Phone is about neutral to the touch, slightly cool. Normally when it's on my desk like this it's fairly cold to the touch, so I'll have to update later when I've put the phone in the same place without charging, but I'm guessing it's a few degrees warmer on the charger than off of it.
I'll repeat this a bit over the weekend here too as I have time, this time I'll set the phone sit on the desk for a while first, check temperature, then charge.
Please do post when you provide input on the poll so we know the circumstances... I mean, if your computer room is 35C and your phone gets 40C charging, I think that's reasonable My office here is around 24-25C.
Charged again today from about 75%, house is around 23C (wife likes it cold..meh) and the phone was 27C max charging on USB.
My AT&T Nexus One purchased June 2 from Google overheats and reboots.
Here's what I've found out:
I charge with the original AC Adapter and this only happens when I'm charging and the battery is LESS than 40%.
If the battery is 50% or higher, it's fine.
When the Battery is less than 45%ish, the phone gets hotter and hotter, from 33C up to 39.3C (is what I last see), then it will SHUTDOWN AND REBOOT. When it reboots, it would be about 37-38C. If it's still under 45%, temp will keep rising again, till 39.3% and REBOOT again, takes about 5-10 minutes for this to happen.
Weird thing is, if you pop the battery out and FEEL it, IT IS NOT HOT AT ALL. It's the DAMN phone that OVERHEATS.
2 nights ago, I was charging and reading in bed. IT DID THIS 3 TIMES IN A FREAKING ROW.
7AM EST, I called HTC, and doing a Device Swap.
Have not received my replacement unit yet. Funny thing is, HTC told me they send out device swaps of JUST THE PHONE, no battery no battery cover. So I have to keep my battery and battery cover. And I told them about my overheat/charging/battery issue, and they said if it still happens to mine, they can send me a new battery.
Anyways I will be testing the replacement unit with my battery and make sure it's VERY low to see if it overheats and reboots.
Other info: This happened in OFFICIAL STOCK FRF91. I'm currently running CyanogenMOD 6 RC1.

Hmm, yeah that sounds like hardware problems to me.. Curious, what are you using to measure? I'd assumed the battery temp stuff was really the battery, not .. something else?
In my case when my phone is cool, the whole phone is cool, not just blindly looking at numbers of course.
Again, would the folks voting really high temps try the things in my first post, and let us know what the ambient temperature of the room is, how hot the phone feels vs the measurement, what's being used to measure it... But particularly I'm curious if totally powering down the phone makes the problem go away.
Dial *#*#INFO#*#* then select Battery Information. It will tell you temperatures there. But I think the temps there is phone temp not batt temp, since in my case when it days 39.3C and I pull the batt, it feels less hot than the phone itself.
Also for my case, it does get hot and reboot while USB charging. Reported 3 time in a row again yesterday and I got pissed and HAD to turn the phone off.
Anyways, waiting for my replacement u from HTC.
Well got my replacement Nexus One today, serial number is higher than my 1 month old Nexus One.
I got it go to up to 39.8C and it did not shutdown and reboot, but stuff started crashing.
Music playing would stop, then if I try to start the song again or choose another one, Music app would Force Close.
Started Navigation app and that right away FC.
Anyone experiencing this?
I think you are using a goofy USB cable, or your room is HOT. Because the only time I've had my phone overheat, I was at a pool, in the sun. The phone's temp was 45 c also. I could still use it, but it was burning hot. An app notified me of the temp (I had it set that way) and I turned the phone off.

I'm using both the original AC adapter and usb cables from google.
Also AC has been on it's under 80F in the room.
The other day on the unit that keep rebooting, when I was navigating, i had to hold it up to the AC vent while i was driving to be able to use it... lol... sigh.
I usually only charge on ac but i think i can easily hit 37-39 while charging for over 30 minutes. Its has been up to 40.5 before i think but there were no crashes or anything. everything was stable (its hot but not enough to be seriously scared or anything)
the room at night is around 24? varies alot but the phone also sits on my bed and/or pillow/blanket. try not to cover it when i sleep.

I/O 2012 N7 now hard shutting down (crashing)

I got my Nexus 7 at I/O this year and I've been happily using it for nearly a month now. I don't know if my device differs in any way from one you can get form google play other than the white back.
Last night I was plugged into my wall charger at around 14% battery and playing SongPop with my girlfriend when my screen just shut off. It was like when you hold the power button on a laptop and BOOM, everything is black. It wouldn't turn back on so I unplugged it and plugged it back in. Got a charging screen so I let it set for a bit.
I came back maybe 15 minutes later and I was at 9% battery, which was odd given I plugged into the wall at 14%. I played with the phone for maybe 30s after boot and it happened again, I saw some weird artifacts on the black screen as it quickly shut off and the speakers played an awful crackly screeching noise. Plugged it in again, came back a bit later, still at 9% and played with the device again, same issue only after a little more time.
I'm currently at work with my N7 plugged into my Galaxy Tab 10.1 charger and charging it from 0 to 16% currently. The device is on but I haven't been touching it (and I don't plan to until it's at 100%).
Has anyone else had this issue?
I cant tell if it's some way I'm touching the device that's causing it to shut down hard, some issue with the battery or charging that is causing a rapid battery drop or even a short in the way I'm holding it when it's plugged into the charger?
I don't really want to deal with ASUS warranty returns already, though I have been unable to find anyone else with the same issue through google, so I turn to you for advice and similar stories.
Mine did the same thing the second day I had it. Now it won't boot. I'm waiting for Google to send me a new one.

Mine did something similar last night. It was at about 6% battery charge and all of a sudden the screen just went black. I went and plugged it in, but it wouldn't power on completely (the screen was on but there was nothing there). I started seeing really thin, small green lines running down the screen. I turned it off and on a couple of times, and finally it booted up. I left it plugged in for awhile, and I just took it out at work to use a bit and everything seems perfectly fine. I wonder if there are some firmware issues with the power management or something. I was all set to put in a return with Google, but it appears to be okay. I'll keep a close eye on it for the next couple of days (I've only had it for a week).

After leaving mine off and charging at work to 100% it seems to be working fine. I used it all last night with no issues. I haven't tried wiggling around the usb cable yet in the port to see if that caused any issues.
Firmware issues sounds about right, some sort of low battery safety feature or something? Who knows. I'll update this thread if I continue to experience problems. I'm already past my ability to return to Google so I'm in no rush to warranty to Asus and lose a development tablet.

(Warning)Screen overheat?

I believe my phone just overheated while charging causing the whole left hand side of the screen to become distorted and its hard to explain but it was very hazy over the whole left hand side of the screen (it has been getting better over the last hour)
After i noticed and immediately turned the phone off , left it for a few minutes then turned it back on to see the whole left hand side of the screen was hazy like bad reception on a vcr or something lol to the point where it was unusable and was starting to give me a headache, i noticed its slowly gotten better and as of writing this its only just seeable, still really annoying for a brand new phone to be doing this
I was using the new CM10.1 at the time (I don't want to say its related) and before this happened i noticed the phone was running hotter than it did on euro 4.1.2, also even while on ac charge, my general- lite usage seem to be stopping the phone from charging(like 2% in half an hour) this may have been dropping charging voltage to counter the heat?
It was also charging from ac with some dodgy international adaptor the supplier sent me, i doubt this caused it though as it has been fine the last two weeks.
To my amazement the screen has returned to normal, i wish i had got some screen shots but was in to much of a panic lol. From now on ill only be charging it in a usb port, will never charge this phone via ac again. Im a bit disapointed in LG for this overheating issue, as it seems every optimus 4x hd user is having issues, please be careful with how hot you let yours get!!!
This is a fault, my screen gets very hot while gaming but display remains crystal clear.

Weird battery issue with SM-T813

I bought a brand new S2 (T813) last Sunday, and finally sat down last night to start loading all of my apps on it. I know I had the screen on quite a bit, and of course the network was active, but it felt like the battery was dropping a lot faster than I imagined it should. I went from 100% to 90% in about 20-30 minutes. That, by itself, isn't too big a deal, though my ancient iPad 2 seems to hold up better battery-wise despite its age, but this morning I woke up and it was still stuck at charging with 98% capacity. I reseated the charger, rebooted the tablet, and finally power cycled the tablet. The last one finally did it, and it got back to 100%.
This has me a bit concerned, though, and since I am still in the return window, I'm wondering if this is normal behavior?
