My TB has seem to be running hot constantly all day even without heavy use. I just checked it after 15 mins of inactivity and it still feels hot to the touch and the battery is still reading 108F/42.7C. Anyone else having this problem?
After 45 min of inactivity I turned off the Wifi and now 10 mins later its cooled down to 38C.
Is it Charging? My phones get hot when they Charge
On the first charge my battery was hot 45c on the second full charge it holds at 32c. All temps are heavy use with and without wifi.
Usually this happens because Wifi, GPS or Bluetooth are on. Turning off can help.
Also one time I had a problem with my Incredible, it was so hot. I finally figured out it was the stock mail app, some reason it was having a problem, so it kept trying to get my mail, but couldn't. So it could be an app. Usually if my phone starts getting hot, I just reboot. I think the app craigsphone causes my phone to get hot sometimes. There is now way to exit the app unless you press HOME, the back key dont work.
What tools are you using to measure your temps?

hi, I am running cm7 with stock kernel. Just recently my phone has been getting really hot. I checked the temp and its almost 110 degrees. I haven't installed anything recently either.
I can leave the phone sitting there not using it and it'll still be high. Should I install another kernel or do I need to change settings on my phone? I am using extended battery too.
Thanks.

Hmm any case on it? When its charging leave it face down too.
I have no case on it. Will searching for a signal cause the battery to get hot? My cell standby is at 54% and it says time without signal 67%

Mine got real hot after loading the latest CM7, while trying to sync all on 4G. It was smoking hot in my pocket, so I pulled it out, and took the Trident Aegis case off to help it cool down. I looked and noticed it was stuck at 3G but still trying to sync all.
I had to do the time consuming routine to get 4G every time I turn on the data, and my GPS was still not working, so the hot battery sealed the deal... back to BAMF 1.8 till the next CM7 release is ready to test.
I ran into this one time and found that turning off Wifi seemed to do the trick. It seemed as though constant searching for an available Wifi network caused my battery to get hot. This makes sense if you read how tethering causes some phones to get hot as well.
Thanks I guess the searching for a single is the culprit bc it doesn't get hot while charging.
Sent from my ThunderBolt using XDA App
I'm experiencing the same thing and the exact cause is a mystery to me. The battery definitely gets hotter than it did with BAMF stripped 2.1, yet I get much better battery life than I ever did with sense. This completely defies logic since the two things that will make a li-poly battery warm are a high C draw or charge, but a high C draw should correlate to poor battery life yet it doesn't. I'm starting to wonder if something other than the battery is causing the heat...

One other thing to add, my battery level went from full to low in less than 2.5 hours when this happened. While I believe it was the battery that got hot, in reality I am not 100% sure. I do know that after turning Wifi off and charging the battery, the problem did not return. I am now very careful to toggle Wifi Off/On as my needs dictate. I do this even though I have set Wifi to turn off after 15 minutes from the advanced Wifi menu option. The Wifi 15 minute timeout was in effect when my phone got hot, so I am fairly certain it did not work as it should have. Hope this helps...
Anyone returning their evo because of a overheating problem? Seems to be a serious problem and don't want it blowing up in my face. Read the article yesterday and checked mine and it charged at 4.348 mv. Or is this a software issue?
You wouldn't happen to have a eBay battery would you? Also the battery may get hot the first few charges. To reach 4.3V, well I'm not exactly sure how that's happening. Take it back I guess but if its your first charges then just give it time.
Unless the phone gives you a warning, or just shuts off its probably not overheating. You would be surprised how hot these can get and still be in a normal heat range. I tax my Evo pretty hard and it will get pretty damn hot, but never overheat hot.
What are you doing when it heats up? Are you playing games, charging, talking. Maybe some more info?
I've had mine in my pocket and noticed that some live wall papers really get the phone cooking. The My Beach one almost burned my leg! I guess my phone turned on in my pocket and it was going to town with random screen pushes. The phone was hot enough to hurt sensitve skin.
I've had my OG EVO get griddle pan hot several times. It has survived as well as the batteries. Every time I think I solved it, the next time it was something else.
Knock on wood, so far my 3VO hasn't got as hot. Yet.
next time you phone gets hot check and see how well your gps works.
there are some funky things going on with this phone.
Playing spider man and game froze the phone got extremely hot had to do a batt pull battery died in like 7 Min's
initial batt life was great like 14 hours and still had 50 percent after a week it got OG evo crappy, factory reset and juice def ultimate and batt is back to great.
Don't know if i should return for exchange.

No I'm using the stock battery and it was just plug into the wall charger and not doing anything. Don't we have 4.2v batteries? Shouldn't it not be charging anything about that?

It did go to 102f but i guess that's normal but sometimes it goes to 105 or 106 while charging.... But I have the evo4g and that never chargers above 4.2v... Just kinda worried... Don't want this phone blowing up in my face.
Haven't had this issue. I've been traveling and have changed the phone quite a bit from using the phone as a game system. It does get warm after 30 mins of angry birds. Nothing extreme however.

It wont blow up on you. You should be safe at those ranges. when you start hiting 115 and 120 thats when you may want to unplug it and turn it off.
I had mine charging in the car mount last Sunday while running google nav, and the LED started blinking red and green. I assume this is the overheat indicator, although I can't find it in any documentation.
I had one weird overheating incident right after getting it activated at the Sprint store. 15 minutes later, it had been sitting on my desk and I go to pick it up and its crazy hot. I quickly pulled the back off and removed the battery, the battery was not hot, it was something behind the cameras. CPU I suppose. I waited a few minutes to put the battery back in but then it wouldn't turn on (overheating protection?). Went back to the the Sprint store for an exchange. Waited, waited. In the meantime I put the battery back in and it started up. After waiting 45 minutes with no help in sight I gave up... sigh. Sprint stores around here are always a PITA.
I haven't seen this problem again but seriously what the f? I went ahead and applied the OTA updates in case they included some fix for this.
Yeah, in car charger mine hit 114 with gps going. Took it back, better but not great with the new one 102. EVO 4g ran hot but that was self induced. Oc etc... Stock shouldn't go above 102 ever

my phone regularly gets to 105F from regular use sometimes; using the internet browser over wifi, playing games (cut the rope got the phone to 107F), charging also heats up the phone. I don't have auto syncing enabled.
is that normal operating temperature?

My question is should a phone be charging over 4.2 when the voltage of the battery is 4.2 max? Wouldn't that greatly reduced the battery life if charged over that voltage? Anyone care to explain? Cos I'm really not sure what the implications are.

The voltage of the stock battery is 3.8V. I am surprised it would see higher voltages but it may have a variance that is +-(.4) even when charging the voltage shouldn't vary that much, but the amperage should increase instead to charge the battery and run the phone at the same time. I am not sure where you seen the voltage at though so if its an app, how accurate is that app. How often does this happen as well?
I've been noticing a good amount of heat up by the camera during moderate use. I thought this was a CM7 problem since I had been on it since day 1, but I am now on UnNamed and the problem persists. After some googling it does seem that many other people are having this problem. Not on WIFI, and not in a poor signal area either. Just wanted to see if anyone had any leads as to the cause. What is a good app for monitoring CPU usage by app?
Yes, it may get a little hot but it isn't something to worry about as far as I know. I've gamed for three hours straight and not had any problems except for a low battery life!
yeah mine gets hot near the camera during use but i dont think its a problem
I use a battery monitor.
From what I've read, it will shut off for protection. I've heard that as long as it doesn't ever get too much above 130 F, you should be OK.
Now if it constantly stays high, there may be a problem. Mine stays around 80 F most of the time and the highest I've ever seen is 99 F but i don't game much or use my camera. One thing you don't wanna do is charge it while hd gaming or charge it in a hot car. My infuse reached 146 F one time doing that.

When I first got CM7 running on this thing, I tore through the market installing the apps I'm used to. When I was finished, I noticed that it was indeed a bit warm in the area you described. It wasn't hot enough to cause discomfort, just warm enough to note.
I notice when my phone gets hot in that area when it is around 30% remaining and I charge it. I also notice that when it is charging, it really isn't charging but battery is draining. When I got home and charged it at 30%, I left it sitting there for about 30 minutes and when I checked the phone again, it was at 25%. GPS and wifi was turned off. I decided to power down the phone and remove the battery for 5 minutes. I started working fine after that. I noticed it getting hot again today when I plugged it in to charge at 40% but this time it actually was charging. I am running stock rom but rooted. Should this be a concern?
Seems as though a lot of people are having a variation of this problem. Hopefully it is addressed soon.
The CPU will always get a bit warm if it's running.
If it's getting very hot when the screen is off, you've probably got some background task wakelocking the phone.
My phone's screen gets pretty hot when I run web videos/flash videos on HSPA.
Runs a tiny bit warm when i'm running pristine 3D Tegra games on it...otherwise no.
My phone seems to be getting warm in the lower left corner of the display when I'm using it and the charger is plugged in. If I don't use it and it's on the charger I do not get this warm spot. It has persisted though multiple ROMs/Kernels. The spot is just above the menu capacitive button and I can feel it on the front and side. Prob only about the size of a dime if it were wrapped around the side of the phone. When it's not plugged in I don't notice the warm spot. Is there a component for charging under that spot? Thought about warranty return but don't really want to get a refurb.
No one uses their phone when it's charging? Will usually take about 10 or so min of playing on the phone to get the spot to warm up.
my phone doesnt get hot there. During use, it'll get hot around the camera, where the battery connections are. Thats about it.

Hmm... Mine doesn't get warm there. I looked at the teardown of the international SGS2 on ifixit and it doesn't even look like there is much down there at all to get hot.
Mine gets very hot if used while charging. As hot as 128F on one occasion. It doesn't seem to matter how many apps are running. Its 105 right now with minimal use. I do keep the screen at its brightest though so I'm guessing that's the issue.

That's dangerously hot. You need to figure out what's causing that. Enough times above 125° and your battery can die or have noticeably shortened life.

Mine get the same way. Extremely hot to the point I can't hold it. Sometimes i play Zynga poker while charging and aftering 20/30 minutes my phone is burning hot and only recieved 1% battery. And sometimes i will wake up and the phone will be hot after not touching it for 6-7 hours and battery hardly charged.
I've noticed that this phone tends to heat up fairly easily..A lot of apps cause it..Not sure what to do about it though..
Mine only heats up noticeably if I play a game or something of that sort, but not really otherwise.

My phone really only sunstantially heats up when I am using any browser. Also fyi, there was another thread on this subject.
Yeah, I turned it off that time. But even if plugged in with the screen off I saw it today near 114. If I use while plugged in it jumps from the 90's to the low 100's. I'm just trying to figure out if everyone sees it that hot. I'm using battery indicator in my notifications bar to monitor.

The bottom right side of my NT heats up during normal use. Also the battery seems to discharge really fast? Is this normal or am I being paranoid. My previous NT overheated really bad once so I excahnged it.
I have been using it for about 30 minutes now after a full charge and its at 90% charge left.

Is it possible you have a run away app that's eating up CPU cycles? Check your battery history and see if something sticks out.

I have noticed the battery getting warm, but it's usually when I've been browsing for a while. It doesn't feel super hot (like my laptop does) but it's warm. I haven't noticed terrible battery life. If I let it sit idle, it goes to about 50% in 8 hours time. If this is an issue, I want to know about it. I'll have to restore it to factory settings and whatnot, but I don't want a faulty device.

There were a number of posts from people who were seeing high battery temps after skipping the OOBE. Did those of you having problems in this thread skip OOBE, uninstall B&N apps yourself, and/or use compromise the B&N applications/services in any way?
Just got mine. I noticed that it does get warm but not too warm to cause panic. Mobile phones start getting warm too if you've been browsing over wifi for a while. Are most people running frosty nooks? Should it not feel even a little warm?
Or maybe you can rate the amount of heat, say from 1-10 how hot does yours get?
My rooted nook gets hot while playing Exitium for half an hour, but not when it's idling.
Not I
I use my Nook tablet quite extensively and I don't seem to feel an unusual amount of heat coming from it. 30 minutes of use and down to 90% is not unusual either. Otherwise, I would have to agree that there is probably an app running your CPU full tilt. Probably not your battery that is heating up either, if you look at the pictures of these pulled apart, you would see that if the battery was what was getting warm, it would be almost the whole back of your NT.

I was actually thinking the same thing. I think the warmth I'm feeling is actually coming from the wifi adapter inside, which would make sense because I notice it when I'm browsing the web for a long time or downloading a large file.
No issues with heating up here.

Only time mine heats up is if I have been streaming from my pc to the tablet via dlna server to watch videos which would either mean its the wifi chip or the cpu heating up.

Just to clarify, you're saying if it is sitting idle - not being used, and the screen is off - for eight hours, it will drop 50% of the battery? I just picked mine up, and after almost 11 hours sitting idle it only lost 5% of the battery. It sounds like you might have an app causing a wakelock.
No heat in mine and it does retain charge while sitting with screen off. I rarely turn it off and charge every day or two depending on use. I read somewhere it is not good to let the battery go completely dead.
Not sure what OOBE is but I have been turning it off to avoid it from overheating really bad like my first book.
Not really sure how to scale it but I would guess maybe a 5 if a 10 is where it wouldn't turn on and a 1 is its cold to the touch.
I used Indrects method.
How would I check to see if a app is doing something like that? Tgps?
I guess I could just leave it on for a day then check to see how the battary is after like 15 - 20 hours.

I skipped OOBE, I used NARS to root. I don't have this problem.
Never heated up for me, not once.
Overall I'm more than pleased with battery life. Watched 40 mins of youtube 720p video with jetvd yesterday (over wifi) and battery went down only by 10%. My SGS2 would've lost like 60%.
