Recently, twice in the same week, my Nexus 7 has been over heating to almost a burning heat. Now, every night I plug my nexus in and its usually around 30%. Then I put it under my pillow while I listen to a podcast and fall asleep. Then I wake up and usually it fine but today I got my temp gun and it read 138° F on the front glass. I looked at my battery status and it showed that it charged to about 80% and then the screen turned on and the battery was draining very fast while on the charger. I think that is when it overheated and the nexus couldn't vent air cause it was under a pillow. Would this screen turning on be a result of a bug in JB or could it be a rouge app? Or could it be that daydreamer thing that is like a screensaver.

What kernel do you use? Do you OC your CPU and GPU?
Oh, I'm sorry I didn't post those details. I am stock with android 4.2.1 with kernel 3.1.10-g22b4fcd. I am unlocked though

I looked at my battery usage history and my screen turned on around 3 in the morning and its draining the battery while its charging. So something is going rouge.

Download trinity kernel toolbox. This app will show you the cpu`s temp. The normal temp for the CPU on 1.3Ghz is about 60-75 °C...
dont keep your seven under a pillow while its charging,. thats the only way that you will get the battery temperature that hot. for a cpu temperature, 138F isnt hot. but for a battery temperature, 138F is very hot.

NEVER put these devices under a pillow while charging! You are asking for it to get fried. I did this with my phone once, and it was too hot to touch once I took it out in the morning.

OK, that solves the heat issue but how can I find what's drain the battery so fast.

Hi, there,
My note battery, or maybe system is a bit wired, normally when charging, CPU only use 200mhz, even in screen off mode, but today it was charging on screen off with CPU jumping 1400mhz, so it makes my note like no charge at all, but when screen on and do nothing the note CPU will drop till 200 MHz, any solution?

Do you have better battery stats and cpuspy installed? Have you tried a factory rs? Maybe something is running in background forcing such to occur?
Yup, I have them installed, I have this situation once, but it went well after a couple of battery taking out and cooling down, factory rs was my last touch, if using 3g, with 10mins of online game, the better battery show 13% used for an hour, is it normal?

13% per hour may be normal when 3G on & u r playing games..it may b even more if u r playing some heavy games..about the charging, AFAIK phone won't go to deepsleep during charging even if screen is off..so, processor will be running @ 200MHz..
Yeah I know, but this time it when to 200 on screen on, but 1400 when screen off.
Anyway, I already fact reset the kiddo, and everything seems to when back to normal, maybe is something I installed.
Thank you all for replying the questions.

Okay, my phone easily overheats if I am charging and using facebook or browser with 3G same time. Also overheats when I am playing Pocket Legends when not charging. If I am charging my phone and Playing Pocket legends, it becomes really hot and just frozes and then reboot after i just unplug charger and leave it alone. This happens in less than 40 minutes. I have a battery app that shows battery temperature and sometimes it goes up to 78 degrees (celsius).
I use cm10 on my phone and never run over 3 apps same time because it causes overheat.
Is this normal for older phones? I have been thinking if I buy that Nexus 4 phone but that is soo expensive in Finland. I haven't overclocked or anything. Can you tell me how to fix this or do i need new phone?
Thanks

You can check with Bat Stat. It's a widget and work very well.
From my experience a mobile completely in idle should stay at 25/30°C, messaging and do some other light things up to 35°C and gaming 45°

Temperature change means that your CPU is working. That's why you use more battery. If you want to preserve your battery on a rooted phone you can use apps like "SetCPU" and set as max cpu speed 1016 MHz. This will not reduce drastically you phone speed but will help you to preserve more battery. When you want to play some game set the max value back to 1500 Mhz

Atm I was reading a book from Play Books and temp is 29. With my Note I had similar values.
The thing that is different between XZ and Note it's that XZ can't exchange hot cause it's waterproof and Note can do more effectively.
XZ has a front and back "glass" so it's more sensible about external temp.
Here in Italy summer it's coming and I'll expect about 30° CPU temp as normal

CPU???? xD I was talking about batt temp, around the camera gets very hot sometimes... how can I see cpu temp?

My fault, i was talking about battery temp. Cpu temp can't be monitored, but i think that is directly propotional with battery temp
Yeah is normal it is a special feature Sony build in. That's foe the winter time to keep Ur hands warm when u use the phone. To bad they do not included a turn off switch for it.

Today I wanted to test how is the battery of this phone. I had unplugged from charger at 6.30 AM and connected to PC for 10 mins during the day. Now I have 33% remain and I went on YouTube, listened songs with Spotify (offline), SMS, FB, Twitter, Viber, Play Book: a normal daily use for me.
I have .253 fw and Doom Kernel with wheatley governor and cfq scheduler. 1026 MHz max - 192 MHz min. Juice Defender Ultimate for mobile data and WiFi always active when I am at home or at work.
About 18h without charge. For me it's an exceptional battery life. (when i hade Note I used to go with 3 more battery in the bag!)
Hey guys i wouls just to ask about your battery temp,and i would to show you if this is even normal for the one

104F equals 40C. That temp is fine. If you do some more intense gaming, it will easily exceed that.
For the phone to do that while not in use, however, could be a little worrying if it wasn't charging. The phone can heat up quite a bit when charging from a deep discharge. Still a bit hot for a charge.
I remember I once had my One X charging. I left for a while, when I came back it was super hot. No idea why, but it happened once or twice in the year that I had it.

Have you guys noticed that this phone gets hot fairly quickly during use? Also seems to suck the battery down pretty fast, too. By product of faster processor compare to the Note 2?
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app
Haven't had any issues. Everything is comparable or better than note 2 with the same usage patterns so far. Going to try some games (like Nova 3) and asphalt to see how it does.

Mine certainly gets pretty warm with regular use. Battery also is not what I was hoping for. I am new to android and the note phones though so am trying to mess around with changing settings and such.

I have a thin case on mine. I notice no heat whatsoever. Also, I've never had better battery life. I use the hell out of it, too. My Note 1 and my Captivate were power hogs, though. That's all I have to compare it to.

Personally, i love the battery life on this phone. Thats coming from an S4. I used to have to put my S4 on the charger before the end of the day because it was in the yellow. Thats from around 740 in the morning til around 6 in the evening. Now, on the same usage, with the Note 3, by around 9 at night the battery is still sitting around 50%.
Wow, any special settings you are using? I am already charging my device today as I was bellow 50% with only a little over 2 hours of screen useage.

There has to be an app running amok, or you are in a bad signal area, or you have every possible setting on to be charging that often unless you have a bad battery. I usually get about 4 hours screen time over 24 hours and usually have 45 to 50% left. Just did 24 hours with 4 hours screen, 2 hours music listening while mowing my yard and downloaded 2.5 GB of data over LTE and had 39% left.

I have a lot of the extra settings turned off. I have power saver on for screen management. Wifi scanning for apps is off. Bluetooth on only when I need. Screen brightness set to auto. Phone is running stock ROM, no rooting. It often feels warm around the camera area. I have been consistently running out of juice by about 12 to 13 hours of use. I don't know....

Pretty much the same settings as mine. I leave GPS on always. Do not use the power saving management features.
Try going into developer options and limiting the number of background activities to 3 or 4 and see if this helps any.

Update. Got mine to 103 F using Skype whilst whilst video talking.
Talking of which the Skype app is ****e compared to IOS version . I couldn't even disable external speaker no option, also when I put the phone to my ear the external speaker is still engaged as is the front facing camera POOH!
No issue here either.....phone is alot faster...battery life is insane....i have never had battery like this with my note 2....i can run for days without charging....great device...highly recommended........you might have a bad unit....you figure they push these out so fast...your bound to get a few duds...i would return for new one.....just my 2 cents.....
I've had no issues with mine but my girlfriend has had a weird charging issue once. In the middle of charging it stopped and said that it was over heating. Thought that was pretty odd seeing as how she wasn't using it at all.

unbearably HOT
Today I was listening to mp3 music off the memory card and noticed the phone got unbearably HOT and battery drain was around 50% in less than 2 hours.
This is normal usage and it should never get warm for playing mp3 music.
I am curious to know how many have a heating issue.
Looks like mine is going to be replaced.

There is most likely something running in the background causing this. I listen to mp3s for several hours nonstop off my SD card without any heating issues. Try killing all apps and clearing memory with the task manager then run the music app and see if the heating issue persists.

Well, for the last few days I was not happy with battery life and was getting a lot of warmth on the back as well around the camera. Last night I shutdown the phone totally and rebooted. Had a few updates pop up for some Samsung apps when the phone booted up. Today, battery has been quite stellar. No real warmth either. I am at 70% charge at end of the day with 11 hours on battery and 2 hours screen time. Interested to see if this continues tomorrow. I would recommend shutting down the phone and reboot to see how it goes.
