Overheating like crazy! - Nexus 7 (2013) Q&A

Hey guys,
My nexus 7 is not behaving normally anymore! It is overheating like crazy! Even by just browsing facebook the device gets a cpu temp of over 70°C and it even got up to 105°C once and then it rebooted, now this also means that I can't do anything with the device: it will not charge because of high temperature, most apps force close too!
I also did a antutu benchmark recently and the cpu scored a mere 500!
what is wrong with this thing?
Can anyone help me?
Thanks,
Noahvt

Maybe there's some process that's running in the background that's over taxing the CPU? Have you checked to see if that's the case? Have you tried booting into safe mode to see if the problem goes away? What steps have you taken to try and troubleshoot?

[Q] Is overheating still present in Jelly Bean?

I remember reading somewhere that it was a software not hardware problem so JB could have a fix for it.
I've never had an overheating problem. I also don't recall many having that problem.

Overheating? I've never had any of my phones overheat, on GB, ICS or JB.
Are people really having serious overheating (as in phone crashing or shutting down from heat) on a stock device? I have a feeling anyone overheating on ICS is running a custom ROM with voltage changes or overclocks.
My GNex on AOKP and stock voltages does overheat while, for example, playing Modern Combat 3.
Ok maybe overheat is a wrong term a bit since it never crashed or force closed. It just gets fairly hot in the area above camera.
And I'm asking people who did have the problem and upgraded to JB.
My GNex does seem to be running hotter than normal on JB than ICS but not by much. No serious overheating problems at all.

Getting hot and overheating are completely different. The phone gets hot where the battery and processor are, that's just how its going to be, especially when playing 3D games.

No no, my battery stays fairly cool (39 celsius degrees) but the area above camera compared to that is really hot. Way too hot than I think it should be. My previous phone - HD2 was never that hot unless I overclocked it.

Around the camera is where the processor etc. is. The HD2 is also severely less powerful than the Galaxy Nexus.
My cdma nexus doesnt seem to get as hot. I havent really noticed it as much as i did on ICS.
I've been getting overheating since Jelly Bean. Keep in mind that google "improved" things by ramping the CPU up when the screen is touched, even if it's to do a simple task that doesn't require full CPU power... this might exacerbate the overheating issue if you're actively using your device.
Way less then usual. Maybe 50% less. when it does it gets a bit hotter.
So in conclusion I think it's better at this job then ics.

Do u have 2D rendering whatever it's called on???
Turned mine off when playing GL games. And it's better.

It doesn't ramp it to full clock speed, it ramps it up one step, or two, whatever.
Ramping it up to full speed on every touch would murder the battery.

I've tested it. It ramps one CPU to full clock speed when you move your finger around the screen.
Try it yourself. I wish I could turn that feature off since using Swype has now become an issue...

While on ICS, it'd get up to around 70°C. Now on JB, it usually tops at around somewhere in the 60s°C.

Overheating and led blinking

Hello guys,
Did any one of you experienced the same thing.
It happend to me for a second time,
While the phone is on charge to use it and this time i was using only the FB app to review some stories, when the phone became extremely hot from the back next to camera and also the display. And at the same time Led started blinking as crazy red&green.
Dont know which app u r using to measure this temperature but its definately not normal. Even when i play some HD games the phone did get so hot. Got worried.
Any experience or advice? Thanks

It can be rom or kernel related. Never had the blinking issue, but device also got hot. You can by try reflashing both, and systemtuner, free on playstore, is a good app.

I do have same thing happen on my hox...i am using viper rom and franco r12 kernel...it was happen when my hox temperature 48°c when i am charging and using my phone…i think it will happen when it get overheat more then 45°c...after cool down then the led blinking will gone on my hox

LED blinking just simple humanity notifications that the phone is currently oveheats. All lithium variants battery wont charge under overheated condition as the itself is unstable..
For quick resolving, turn off wifi could be a quick solutions..
To dig into root-caused, you may wanna check any mis-behaving apps before suspecting kernel.
Well my phone is with the latest stock rom. Didnt flash any custom rom, even not rooted.
Also i was only on 3G internet, bt & wifi both off and also with sync off,
As i said at first post i was only checking through the FB app some stuff, and couldnt believe that FB app can overheat my phone such for less than 10 mins
You are right that the blinking is most probably notification for the overheating.
Did anyone know what is the maximum temp which the phone should not reach? On gaming for example when all the cores are using.

On gaming the phone goes to about 77 degrees, according to system tuner. It feels hottish, but not to bad. I once had it up to 88 degrees while playing with a weak signal. Have you looked at what is eating the power, yet?

FYI, My LED will blink while battery sensor catch up around 48C.
FB App is well known lousy and slow app but it probably not the cause, what we said was to check against faulty backgroud app for your problems and take a look on battery stat find out unusual battery drainage.

Don't worry, I've had the exact same thing happen to me before, but I think that was ROM related since the ROM was in very early stages of development. I do also remember waking up one day to HOX overheating (probs never got a chance to get into Deep Sleep). It was so hot, I thought the internal components had fried up. And yes, the Red and Green Notif Light blinking is definitely a sign for overheating. So I quickly changed the ROM and ever since that day, nothing's happened. But anyways, you did say it was the stock ROM so what I suggest you do is clear the processes and look carefully at when it specifically starts becoming warm. It could be an unstable app you might have installed. But then again, the kernel could be at fault. Probably setting the CPU at a clock speed it doesn't require.
Hope you get this sorted, good luck.
hi guys,
thanks for the replies ,
My HOX is 2 months old and I'm not feel ready yet for custom rom, in case something gets wrong.
I have better battery monitor installed, and so far the phone stays in ~90% deep sleep
no indicates for interrupting program while sleep.
so the problem I guess is really with the kernel , when the phone is awake and using some apps ..
but every time when i check the processes there is nothing "extra"
i didnt understand how you guys measure the phone temperatures.
Regards
Yesterday i was watching a movie via mhl using mx player software deconding and after 18 minutes i got 58.8 overheat... My phone was extremly hot... But than i saw that mx player s/d its not for tegra 3 procesor.. Im using arhd 7.2.1..

Hello guys,
After second time my phone got huge overheating i start watching what apps & services running.
Let me share with you my findings so far.
I noticed 2 apps which constantly keep apper even i force close them, and ofcourse at the end i uninsall them,
And suddenly the phone started working normaly with no overheating till now.
Even if i left the phone all night with wifi on, sync on, after aroind 12h the batter was moved only 5%
The apps wich i removed were "bump" & the eufa "euro 2012" official app
Hope this helps someone else

Glad you listened and had a look at what is eating the battery. Its not always the obvious answer. Glad your phone is running normally and not dessert style?

Specific freq for specific app?

Hi there
Im currently playing clash of clam on my galaxy nexus. But i was worried because the game causes my phone to be extremely hot in less than 5 minutes. (Its felt likebu sunbath ur phone)
I notice that its not the battery that heating. Its the component above the battery, just below the camera.
I thought it must be the processor overheat due to the game overdemands.
(Seriously, other game that uses data doesnt cause similar problem)
So, is there any apps that can control specific frequency towards specific apps?
I want to try set the frequency for clash of clan to 800mhz and hope that the problem be solved.

Update kills battery life and adds lots of heat

Kitkat update killed battery life and makes the tablet extremely hot near the camera on the back. What gives?
Sent from my SM-P600 using XDA Premium HD app
I don't have a solution but the same problem. I'm fine with it getting warm but it's getting really hot! It's great that we have kitkat but it's not all that stable yet.
Restarting seems to help temporarily. Feels like something gets stuck and then makes the CPU run extra stuff but I don't see anything with my wakelock analyzing apps...
When it is in "battery-eating-mode" even browsing or watching a video makes it run hot!
Generally it indicates that a file or service has become stuck, or hung. For me it's common for the Samsung.index.service to get stuck indexing a file and sometimes lasts 3 days before it's resolved.
You should use some kind of monitor to see whats causing it.
Gsam battery monitor does a good job of showing rogue apps, and battery and heat.
Also a CPU monitor is included in the debug/developer which can also show the culprit.

I quite upset about this now. I reset my device and still have the same problem. My tablet used to be excellent and had great battery life. Now Kitkat Haase it basically useless because the battery drains so fast.

Indexservice uses 30 percent of my battery. I read that happens if you have lots of pdfs on an external SD card, but for me that is the whole point of this device. If I just wanted to play games, watch videos and surf the Web I would've gotten an ipad. Really dissapointed with Samsung here. Did they not test the device before they released the update? Or do they clock out of their jobs and go home and use ipads?
Sent from my SM-P600 using XDA Premium HD app
Yeah the indexservice did the exact same to mine, Samsung were no help. Happened even when I put PDF's on internal storage.
I had no other choice but to root it and freeze the service with titanium backup, I really didn't want to, but I was left with no other choice.
As I had gone that far I also froze a bunch of other Samsung apps/services - I am so glad I did, the tab absolutely flys along now - feels like a different machine.
Root it, you won't be disappointed
Sony released a statement suggesting disabling the Google backup functions to improve battery life with kitkat Roms. If you don't need those maybe you wanna try that as well.
Settings/general/accounts and save&backup
It will likely fix itself after a few days. It happens on mine every few months for a day or two. Then it settles down and works normally. Same on all Samsung devices.
Has nothing to do with KitKat.

I did some testing with an app to check cpu frequency and here's what I found:
Sometimes the tablet goes into "fury mode". Which means that as soon as there is any task for the cpu however small it may be it drives all cores to max 1.9ghz and full speed. Which means even while I'm browsing or watching a video the tablet runs about as hot as when playing an intense 3D game. And with equally bad battery life.
Really bad performance/efficiency handling. Like now I've been browsing(chrome) for 30 min and it ate 15% battery life and it's extremely hot on the back where the cpu is. There aren't any special processes running I've checked with watchtower. Cpu load is not that high but frequency has been constant 1.9ghz max speed on all cores... need custom Kernel PLZ.
I have to say though this is not always the case. Sometimes after a restart or when it was laying around for a while this fury mode doesn't happen.
just rooted and froze indexiservice using titanium backup...hopefully this will help
Ok looks like everything is good now.
Rooted and used titanium backup to freeze all the stupid stuff that was causing the device to get super hot

Overheating

Hey,
I still own and use an LG G4 as my second device, but the overheating is becoming a problem since it throttles like hell when the device overheats. Any advice / possible fix?
Thanks
What temperature is the phone getting to? you can install a cpu temperature app to check.
