Many posts about Battery temp but what about CPU Temp??

Hey all im seeing many posts about battery tempratures etc but what are peoples CPU temps like?
Like many others my phone aslo gets VERY warm during intense use.
Im using a paid app called tempmonitor which allows you to both view CPU and Battery temps.
after around 15/20mins of playing riptide i notice that the CPU temp has shot right upto anywhere between 60 and 70oC games still run fine with no lag etc is it possible that some of the heat from the CPU could be increasing the temp of the battery?
Just a thought please post your CPU temps too if you can.

your most likely right but that app doesn't work on my phone only shows battery temp.

You guys obviously haven't seen the images of the Endevour stripped down. The Endevour has a copper heatsink/EM shield that covers almost the entire underside of the phone that helps spdread the heat generated by the CPU away from it. This would add a small amount of heat to the battery but in my opinion it wouldn't add enough to cause any damage to the device (and the pictures seem to comfirm this).
My main worry would be the cpu temperature. Your images seem to show it running hotter then my overclocked PC has done ever but again as long as it is within the safe limits for the processor then it's not an issue.
All this does come with a caveat though and that is can we trust this app to read the temperature sensor correctly and reliably? Does Nvidia or HTC provide one we could use? I would trust anything provided by the chipset or deivce manufacturers over some random thing downloaded off the market.

Solution to reduce thermal throttling on Nexus 5X?

Is there a way to reduce it? My phone slows to the pace of a sloth far too frequently and it seems correlated with temp.
I'm assuming that's the cause because when I look at the CPUs in CPUz the last two go down to 633MHz when things are getting slow. Also seems worse with a case but could be my confirmation bias. This is particularly apparent with the camera, Maps, and when coming out of doze.
Is there a more conclusive way to figure out what is causing my Nexus 5X's occasionally brutal performance?

Well, what exactly are you doing with your phone that's causing it to throttle itself? I think with a stock kernel the phone begins to throttle and eventually shut off the Big cluster at 36 or 37 degrees Celsius (someone correct me if I'm wrong). If you flashed a custom kernel, most here have had that limit raised to 46C.
Last weekend I used my phone quite a bit for strenuous tasks including Navigation, Google Maps, lots and lots of pictures and 1080P video. The phone got noticeably warmer, but when I checked my kernel management app, the CPU temperature wasn't even close to the throttle temperature. Unless you're gaming or constantly benchmarking your phone this really shouldn't be a problem. Especially when coming out of Doze. The phone doesn't immediately enter Doze, it waits a while and there are factors that play into its decision to even enter doze in the first place (like laying on a flat surface for X amount of time). So when a phone is exiting Doze because of your input (turning the screen on) the CPU should be quite cool (maybe 22+ degrees). There's no thermal throttling there. The Big cluster shuts off when the screen is off for the sake of battery life, so maybe the lag that you're experiencing stems from the lack of the Big cluster being on for the first second or so when waking the phone back up.
I'll agree that the SD808 isn't a stellar chip; maybe even embarrassing. It's not blisteringly fast, but it certainly isn't slow. There are ways to speed up performance and improve battery life at the same time, which I'm sure you'd appreciate. Unfortunately you have not specified if you're running a custom ROM or kernel, so that's pretty much all the advice and information I can give you right now. But, if you're currently running stock, I'd highly recommend you unlock your bootloader and try out some of the custom (and more lightweight) ROMs that this community has to offer as well as some great kernels. That should make a noticeable difference right off the bat. Then you can dive into the nitty gritty details of tweaking and whatnot if you desire. Check out the links in my signature as a starting point. If you're looking for optimization and speed (like I do) then you'll be impressed.

Thanks for your reply.
I switched to ElementalX about a week ago and it may be a bit better now but it's hard to tell. I've also been using a spigen slim case, maybe that is causing heat to accumulate too.
I don't game. My usage is Maps, Facebook, Snapchat, camera, chrome, hangouts, Spotify, and textra.
I use greenify and amplify as well on xposed. Disabling xposed doesn't seem to make a difference.
Can you confirm that ElementalX throttles at 46C and stock at 36C?
I'm interested in your recommendations. When running geekbench it takes about 9 minutes for things to really slow down.

If you search the ElementalX thread you can see that the developer, Flar2, was getting very frustrated with the thermal throttling on this device (others were too, as well). You can read through the progression and, eventually, the decision to apply a "thermal fix" or raise the thermal throttling limit. The threshold is 46C now. Confirmed. The stock thermal throttle threshold is 10 degrees less than that from what I've read. I also remember reading that Franco did a fair amount of research into the throttling issue and found that the CPU was capable of going over 50C with no issues (but aren't recommended), so the limit in place now by the ElementalX kernel is a safe one that shouldn't be exceeded. He probably didn't make it any higher so he wouldn't be found liable by any users if they overheat or damage their phones.
I have no experience with xposed and everytime there's a compatibility issue, hard reboots, etc. it's always because of Xposed. So.. Yeah.
I also do not use any tweaking apps that supposedly save battery or whatever. I let the operating system take care of that. I do use the L-Speed app (again, in my signature) to disable certain things like debug logs and what not to speed things up slightly. Again, I highly recommend trying Ubermallow and Phasma Kernel as those have been my choice, after trying many others, for some time now. Also, I'd look into the interactive governor tweaks after you've settled on a ROM and kernel combination that you like. That's where you can fine tune the way the CPU governor on the phone behaves and can really make a difference in battery life and fluidity of the device.
Lastly, a case can make a difference with cooling but I've never really found it to be an issue. Maybe I'm just not hard on my phone enough.

A member on the 6p forum came up with a hard mod that does this with a special thermal paste better then stock . Requires tearing apart the device though ...so its risky but his results looked promising

Google just agreed to take back my device so I only have a few days to try things and make my decision on whether to keep the phone or not.
Thank you for your thoughtful responses and suggestions.
Since I started using the phone outside of the case it actually seems much better.
Regarding the extreme slowness coming out of doze, it only occurs when in doze for a long time. Presumably because the phone tries to catch up on all the sync activity that's been paused for the last 12h or so.

I think I'll try your suggestions and remove greenify, amplify, and xposed to see if things improve. I do agree that the system should be managing those things.

Yeah, give it a few days. There are many ways to combat the throttling. Got my phone to 41C today while using it out in the sun. The Big cluster is limited to 633MHz at 36C and shut off at 41CC. The 46C built into the kernel is most likely for the LITTLE cluster to start getting throttled. Check the attached pics below.

Thanks. Btw what ROM and app is that?

ROM and Kernel are in my signature. The app for managing the kernel is Elementalx Kernel Manager and the app to add CPU usage overlays and stuff is called Trepn Profiler.

Sounds like the opposite to me, the phone might be slow because of software on the device not playing nice which causes the SoC to work over time (normal computing + rogue app computing) and can cause the device to over heat and throttle.
There's no reason the device should be slow after a period of doze. That tells me the device is having software caused slowdowns that are not related to thermal throttling.
It takes roughly 12 minutes of 100% sustained load (only synthetic benchmarks) to throttle the 2x A57 cluster, and I've never seen the 4x A53 cluster throttle under any conditions including hours of heavy gaming they stay at 1.4Ghz at all times.

Yesterday I was using GPS to drive and Spotify was streaming. The phone got really hot and unresponsive and Spotify began to stutter. Was unable to even launch textra to text someone.
This of course only started maybe 10m into the drive. The phone is fine while cold.
Maybe I have a defective device but my benchmark stress tests give similar results to other people.

this is consistent with my experience. GPS and spotify (actually almost any app used concurrently with spotify) will cause the phone to have horrible lag.
also, don't text and drive

Interestingly, today when the phone was on battery saver it seemed much faster. Maybe more throttling could help things more than less?
Of course not exactly faster, but more consistent and no unbearable lagging.

Yesterday I flashed the stock firmware files other than user data. Unfortunately I lost root and it seems like I now need to reformat data to get TWRP going again but until then I'm fully stock. Does anyone know a way around that?
I haven't done enough testing to be sure but things seem to be running more smoothly for now than they did with root and ElementalX 1.06. However just writing this i can feel the phone heating up and becoming less responsive. The bottom 2 cores are offline with SoC at 36C and CPU at 56C when I switch to devcheck to check. Other 4 cores at 1440MHz.

I've been having issues with thermal as well. Installed ElementalX along with the governer tweaks GhostPepper profile. When charging (this makes the device really hot) music begins to stutter, coming out of Viper4Android.
When not charging, slow accumulation of heat makes music stutter, same software used. Go figure. Maybe V4A is too demanding on the 808 chip, but I fear if this doesn't cut it, then I'll have to switch phones the next chance I get.
Oddly, this happens when screen is off - the music stutterings. I've thought about Doze and battery saving apps, and have disabled Doze for V4A through the battery optimize pane.
The phone constantly loses battery, around 2~5% an hour, I know thats not too much but my previous phone lost about 1% every three hours. This was a Note 3 Neo by the way. Installing Xposed and Amplify, Greenify and PowerNap should help, but I've had stability issues when using xposed. Maybe later.
Oh, and one last thing. My phone's thermal limit is set to 55 degrees Celsius, but it still feels like it throttles at around 39 or so. Maybe EX Kernel Manager isn't saving the changes, but either way... It throttles too much!

That could be because of the custom software and CPU tweaks or your V4A installation. Using those settings always has the potential to cause issues and I would troubleshoot there first.
Minimum CPU performance with stock settings is 4x A53 cores at 1.44Ghz which is still fast. If you've ever use one of the more recent Moto G devices you'd know it doesn't stutter playing music when it's cold and neither does this device when it's hot.

Setting the throttling temp limit to high will decrease performance, see here for details:

If its cpu temp then no wonder it's always throttling the cpu is nearly always above 40°c.

Heating no matter what - getting hopeless

Hi All,
I'm using my Z2 since 2017 Jan. I've unlocked the bootloader after a year (non-treble), and since then I've used AEX, Bootleggers etc. Last week after i've switched to carbon rom, I've noticed heating for normal usage. Normal multitasing (Facebook, Chrome, 9gag app) = 45-55 degrees of Celsius. I've switched between a couple roms, no change. This is when I've decided to start over - ZUI 1.9 - bootloader lock then 3.5.X for the baseband, then bootloader unlock, new TWRP, Treble this time. I've tried AEX 5.8 and now ArrowOS, but no change, when I wake up the phone 30-32 C, then when I open something up 40-45-47 very quickly. Is there a way to fix this, or maybe I have HW issue?
Thank you

There are thermal mods available for aggressive throttling of CPU for achieving lower temps. You may also try using a kernel which supports editing on fly, like nameless (using kernel editor app from play store) to underclock your CPU / GPU for less heat.

Are you mad or what? 45-55 degree celcius is very hot.. my phone is always under 40 even under sunlight with extensive video playback and browsing and around 45 when playing pubg.. this is what i can call warm.. not 45-55 with light use, i suggest to use characteress's thermal mods to cool down your phone

Pardon me for being a noob, but I am unable to understand how can a software cool down a phone below ambient temperature?
I am from a part of India (Kolkata) where often Ambient temps hit 45c outdoor !!
Some input would be really helpful.

I agree that ambient temperature plays a big role in device heat management, but software(thermal configurations) play a huge role in regulating temperature, you can experiment yourself, just underclock processor in kernel adiutor to about 1.8 ghz and heating will be reduced significantly, our device has sd820, which is known to have heating issues in many devices. It's a quite powerful proccesor(2.15ghz) , so when all the cores are performing at their highest (like when playing pubg) ,heating is bound to happen . So by underclocing to 1.8 ghz you can reduce it. And regarding thermal config files, they are just files that throttle the performance of the device when it's heating, to cool down, sure your device's performance will take a hit, but this will cool down your phone

Thanks for the long reply. But being a noob it seems I am still unable to find the answer for my question.
How can a software cool down my device below ambient temps?
As far as I know, no software tweak can even push device temps below ambient. And ambient being 45c, device will for sure run a few deg over that. No matter how much tweaking is done.
So not sure how I am "mad" for calling 45-55c range normal !!

Question Random 100% CPU usage while gaming

I don't know what to do, every time I play Asphalt 9 or COD Mobile the first games go very well but there comes a time when the CPU reaches 100% generating FPS drops (Despite using an External Cooler)
I mention the random thing, since I can play several times in the same scenario (in the case of Asphalt 9) and the CPU usage reaches 100% in areas where in the previous games it did not reach 50%
What do you recommend to solve this problem?

can be cpu frequency drops in case of overheating.

Maybe your phone is overheating due to high usage of games and check if there are background running apps, it can also consume Ram usage.

Question [PSA] Android 13 thermal management is better than 12.

On Android 13, I have never once hit over 100 F on my P6P (not even charging at 30 W + 5G w/o processor throttling using FKM and watching TikTok). Previously, doing anything slightly intensive would heat up my phone in 5-10 min and stop charging once temps hit 104+ (even when using Franco Kernal manger to throttle my processor). I have also tried other combo of intensive apps/games. Finally, the phone feels usable. Just a FYI.
Although not scientific, I do believe the thermal issues will be a thing of the past come 13 updates.

Good to hear I'm not the only one with a similar experience. Indeed, after flashing A13, my P6P doesn't hit 37°C/100°F in a matter of minutes, like it would previously. Simply switching between Infinity for Reddit, telegram and Brave Browser would make my Pixel reach those temps. Unacceptable. I'm so happy they finally did something about this problem.

Thank goodness I haven't been using cases with my P6P. Mine was still getting warm under use but wasn't down-throttling itself due to temperature spikes.
