I noticed that my refurbished Note tends to get really warm, so I installed the System Tuner app to check the tablet's CPU temperature. It turns out that the Note's CPU temperature idles at ~50C and goes well into the 70s under moderate use (internet, facebook, etc). Is this something I should be worrying about? I only got this Note today so I can easily get it replaced, but I only want to do so if this is out of the ordinary. What're the typical operating temperatures for the Galaxy Note, and should I be worried that mine gets so hot?

I just noticed that under heavy use such as decoding mkv the phone can get a bit hot. Especially in the upper part of the display under the samsung logo.
Anyone else experience this?

My SGS2 gets fairly hot when the CPU is busy on the backside right below the Camera, which is pretty much in the same place, just on the backside instead of frontside.
I'd say its normal behavior. I've noticed it is especially bad with applications or games, that use a lot of CPU cycles.
Being as powerful as it is, i wouldn't be surprised if the SGS2 uses up more power when the CPU is active then older phones. Power usage for doing the same amount of work should be lower then older phones. However some applications don't limit their CPU usage, and therefore you may end up using more power (phone getting hotter) then you would on older phones.
Well it is after all one of the thinnest and most powerful smartphones on the market.
Power = Heat
Thin = Little cooling space = Heat
Heat + Heat = Much heat
No way it's overheating though. I think that would be possible if you overclocked it but I'm fairly sure they've tested it for overheating with stock frequencies and voltages. If you read the manual it probably says that you're not supposed to use it for long periods of time in direct sunlight to prevent overheating, just like it says in almost every phone manual. At least iPhone shuts itself down if it gets too hot and I wouldn't be surprised if modern Android phones did that too.
Hi, I'm no expert, but 70°C is quite a lot, isn't it?
And I was only browsing market...

You said it yourself, "Heavy use", the S2 is just a handset after all, not PC with liquid cooling or something.
The CPU produces a lot of heat, it's a powerful CPU, the device is thin, so:
powerful hot CPU + thin choking case + long time heavy use + your warm hands all over the device playing games and surfing the web etc = very hot device.
Try maybe to change the kernel !
Not sure if it's normal but once my phone went up to 53 degrees c while charging. I unplugged it and waited, it went back to charging at 46 degrees c.

I overclocked my s2 to 1.6ghz and when i play 3d high graphics games the temperature goes around 40c to 48c is this normal it happens when i run at 1.2ghz as well just the phone fells less warm then when i do it on 1.6ghz what is the normal running temperature on a galaxy s2 im mostly running on 29 Celsius on idle this is battery temperatures
Yes it is normal, say thank you to Samsuck .
Ofc at 1.6 the problem is probably (at least it make sense) a bit more compared to 1.2.
I'm running subpsyke's CM7 port on my u8160, and have overclocked the CPU to 691mhz using the the smartass governor. The processor runs at 600 by default. Any higher than 691 and it immediately locks and restarts. At this speed it doesn't reset any more often than at default, something this phone did every couple of days even before I flashed the ROM, and it never locks up.
So my question is: at what battery temperature should I start getting worried? During browsing it gets up to around 25 to 28C, but when plugged in and being used I've seen it at 36C occasionally. I have a feeling that's pretty high.
Watchtower isn't showing me any processes eating up runtime erroneously either.
I'd really like to keep the higher speed, it's just enough to view higher quality video on this toy.
EDIT: The battery temp sensor is the only thermometer on board, I think. AndroSensor picks up another one but its forever 'waiting for event' so I don't think it's really there.
Just picked up an XT1527 (full package, box, accessories, everything) from a craigslist seller for $40 - I figured it would give me something to play with until Motorola ships my "free" Moto X (32GB 2013 model) as a replacement exchange for my old Atrix HD which bricked when I installed the last update for it. For the record, this is the Cricket model.
Upon playing around with it for the past few hours, however, I've noted it tends to run just a bit warm even when I'm not really doing much of anything so I started checking into it - I'm still pure stock, mind you, 5.0.2 build LXI22.50-13.4) and I'm thinking about rooting it and perhaps checking out the CM12.1 build but there's no hurry at the moment.
Having said all that, I grabbed CPU-Z and took a peek at the SoC specs: it shows an idle speed of 800 MHz for all four of the cores even in spite of them having a 200 to 1.2 GHz range. One would think that the device would ramp down to 200 MHz when idle and not doing much of anything at all but, that's not the case so far.
So I grabbed System Monitor Lite to check just in case CPU-Z was reading things incorrectly and got the same exact results. Upon checking the pie graph it clearly shows a range of 800 MHz to 1.2 GHz and nothing below it.
Has anyone else noted this issue with the Moto E 2015 model or... am I just so new with this thing (having owned oh, maybe 200 other devices in the past decade and doing some rather intensive customizations on 'em) that I'm missing something here and just not even noticing it?
Had hoped to keep this device relatively clean and stock but, it appears that's not practical if this CPU speed situation can't be resolved. I see there's basically only the one custom kernel available so far (Squid) and while I'm not opposed to using it once rooted/etc I'm still curious as to know why this thing isn't ramping down the clock as it should. It's using the default interactive governor as well, would be nice to be able to alter that but again that's where it gets more complicated.
Anyone else noted this on their XT1527 (or any of them, really, just as long as it's a 2015 model) or would someone else that's running pure stock be willing to check their CPU usage with CPU-Z or System Monitor or something else and see if it's not ramping down below 800 MHz as it actually should? Obviously the battery life would dramatically improve if this thing would slow down as it should - there could be some new Qualcomm trickery at work here that I'm not aware of, but if it's capable of dropping back to 200 MHz, it damned well better.
Any comments and suggestions are appreciated...
ps
Also I've noted the GPU doesn't ramp down to 200 MHz as it should either, it hovers at 310 MHz almost constantly which again is just another waste of battery when staring at a static image on the screen (save for the info updates themselves but that's not really a thing that should or would trigger a big spike in GPU speed).
o.o thank you so much. You'd wonder why. Well, yesterday (I think) I made a topic about how my phone drains battery abnormally and I just checked with the app you said (cpu-z) and it seems I have the same problem. My phone feels warm almost all the time and it also keeps working up to 800 MHz in all cores. Also, I own the same model and someone in the other topic told me that battery should last 2 or 3 days without doing something. Oh anyway, thanks because now I have a hint about what's going on. Maybe its a manufacturer problem.
For some reason, Motorola set the CPU idle speed to 800 MHz. I don't know why. I lowered the idle speed to 400 MHz on my phone, and I'm not noticing any performance degradation. I haven't noticed any heat or battery issues though. My phone stays fairly cool, even under heavy load (like running benchmarks repeatedly). I've undervolted my phone slightly, that may reduce heat a bit, though I don't recall having any heat issues without the undervolt either.
Well squid, I'm guessing you are using a pretty customized setup at the moment including the kernel you've created so, I'll most likely end up getting a similar situation I suppose. Since the Snapdragon 410 can do 200 MHz to 1.2 GHz it damned well better do it; if Motorola for some reason chose to "hard lock" it at an 800 MHz idle speed that's a bit ridiculous and will only serve to hamper battery life overall.
Performance isn't the issue here since as soon as some CPU power is required it'll ramp up as expected - the issue here is the 800 MHz "bottom" which should actually be 200 MHz. That's a big difference in terms of overall battery life in the long run.
I owned an LG Tribute in late 2014 and was regularly getting 8+ hours of SOT with that which is powered by a Snapdragon 400 (1.2 GHz quad core) and that has a 2100 mAh hour battery - the Snapdragon 410 in this Moto E should be better for battery efficiency + we've got a 2390 mAh in it so, as long as it's ramping down to the 200 MHz "bottom" that it actually should be hitting then I, for all intents and purposes, should be able to expect or even exceed that 8+ hours of SOT without issues. The Tribute has an 800x480 panel in it, the E has the 960x540 so in the long run that increase in pixels should be covered by the increase in battery amperage (290 mAh more).
This Moto E 2nd gen model should be able to do 7 hours of SOT without breaking a sweat, even with cellular/Wi-Fi/Bluetooth/location services on and functional.
At least that's my goal with it... I'm on my first full charge since I bought it earlier today and currently at 58% with 3.5 hours of SOT and that's using Wi-Fi a lot with video playback as well. I've been keeping on top of the Baltimore riots that are happening presently and monitoring things using Scanner Radio Pro as well as a lot of surfing for info and news too. So far so good on the battery life, but obviously it can be much better as long as that CPU speed can be brought under better control.
As a new owner of the Z5C (rly impressed so far ) I couldn't help but notice the heat, courtesy of the SD810 I assume.
So i've started monitoring the temps for the past few days with CPU-Z and Cpu Temperature.
For the most part while doing everyday tasks such as phone calls, news, music, Whatsapp and so on the temperature is around 30-40ish which seems reasonable and causes no concern.
Whilst doing something more intense such as running a game, installing/updating app, or recording video the temperature jumps to around 45-60 which again seems reasonable.
There are sudden momentary (2 second) spikes to 70's 80's usually while doing heavy R/W tasks such as installing an app.
Battery temps usually hover around high 20's to mid 30's whilst doing normal tasks and during more intense tasks can jump up to around 40ish.
I was wondering if other users here who also bothered to monitor their thermals are experiencing similar results or not?
Also am curious to know if someone knows what the msm_thresh threshold is for the Z5C i've noticed mine topping at around 41..
Thanks
I have been getting pretty much similar results, albeit a bit lower temps due to disabling a few cores. Those temps are perfectly fine, as long as the battery dosen't get to the high 40's. The throttling stats when the battery reaches 43°C and clears when it get down to 41°C, you can find the throttling thresholds in the file called thermal-engine.conf located in /system/etc/
