Nexus 4 throttle

http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
Swedroids test
It throttles at 36 C and shuts down at 59 to 60 C.
They should increase the throttle to 45 C and when 45 C is reached make the throttle more aggressive would be a better solution.
What do you guys think?

If it gets to hot people get the yellowing... I would rather run cooler and not worry about it.
Is this throttling effecting real world usage or just benchmarks? Not being sarcastic, asking a question.

Well i dont know, i dont care about benchmarks, just thought about informing what i found.
And increasing the throttle level and making it more aggressive later on was just my opinion.

I would like to see a comparison with the iPhone 5 and Galaxy S III on what temperatures they shut down.

I think that the video was pretty painful to watch! lol WHO on earth would run a phone to death like that?? Hope they have an extended warranty... For real though, I would like to see them bump up the throttling temp a lil but in the real world most users will NEVER experience something like that because that app is meant to run your phone into the ground! I hate that they even make benchmarking apps cause it makes me competitive but I have found that the N4 is FAST as hell so I don't need anything else to prove that to me... Good vid though for the info but lets all step back into reality...

I'm thinking the S4Pro is rated to a higher temperature, and the thermal shutdown is really more for battery health than processor health... Regardless, 11 minutes at 100% load with no real cooling system...

Does the Galaxy S3 also shut down at the same temperature?

12 minutes with the CPU pegged at 100% on all cores with no cooling is impressive, IMHO. Yes it clocked down to 1150MHz but that's plenty fine.
No real world task will come close to pushing the processor that far. I doubt even gaming will task the cores so much that the phone throttles them back.
A lot of modern laptops won't run 12 minutes of solid prime95 before clocking down. This c2d 2.8GHz laptop I'm typing on now will clock down to 800MHz after 15-20 minutes of prime95...but it doesn't throttle at all when doing real world stuff, even compiling or encoding etc.

In my opinion the throttle should engage at 43-45c because at 36c its idle temperatures when the phone i just on stand by.

Ok I fear that's a real problem. What if I want to play a graphic intensive game for a few hours? Expecially on a hot summer day?
Could the phone shut down?

So much for Qualcomm's butter test

In the video description you can find:
"The reason as to why we published this video is because we've never experienced temperatures reaching ~60 degrees C before, nor have we ever experienced a phone shutting itself down after just 12 minutes of continuous full load, nor have we ever experienced such aggressive thermal throttling. It pretty much throttles down instantaneously from 1.5GHz to 1.2 or 1.1GHz during heavy load.
All temperature readings are presented in Celcius.
The Nexus 4 seems to have some issues with heat development. At least if we are to believe our findings. There might of course be a possibility that our unit is faulty. We are however not alone according to the Google Android issue tracker: https://play.google.com/store/apps/details?id=com.into.stability&feature=.... A google search on the matter will also render lots of user reports concerning heat issues.
In comparison the quad core Galaxy S3 (3G) battery sensor reports ~41 degrees after 13 minutes of full load with the screen set to 100% brightness. It does however lower the CPU frequency to 800MHz at times, but mostly run at 1.4GHz. Our IR meter reports about ~34 degrees if we go ahead and measure the hottest spot on the back of the phone (area around the camera lens)."
For me, this is a no-go. I wouldn't buy a phone that shuts down after a few minutes of processor stress testing. Can somebody tell if the same happens with his N4?

Thing is that if you search the web for this problem, you get a lot of hits about people have thermal issues. I hope it just is a defective unit but it seems it is not the case. The S4 pro seems to be generating to much heat and requires too much power. That's why it empty's the 2100 mha battery a bit faster compared to other devices.
Maybe the S4 pro is more suitable for tablets and not phones.

Very few applications will use 4 cores. Hell, most don't even use 2 cores by default. So the chances of you maxing out all 4 cores in routine usage isn't very likely. The extra cores typically benefit smartphones when one process is utilizing a core already, a different process just gets thrown over to a different core so it doesn't have to wait for CPU cycles. Most smartphone use is "burst-y" so this helps end-users out quite a bit.

99.9 % its not the S4 Pro`s fault, just the lame battery from LG. I mean WTF after 15 secs it clocks down !!!!

Yeah, thats weird. But I could live with it, expecially when the phone runs buttersmooth. But if the phone shuts down after a few minutes of processor intensive tasks that's a big problem. I know that barely any app is using 4 cores simultanously, but what happens if you stress-test only one core? Does the phone also shut down?

This doesnt seem that bad, you're stressing it pretty hard which wont ever be done in real word conditions, for example take intel burn test, most people find this stresses the chip to temperatures 15C+ over any possible real word tests/usage.
You say the SGS3 throttles to 800Mhz at some points well thats pretty poor is it not? Clock for clock the s4 pro is superior and so clocking in over 300Mhz faster when throttled its pretty good id say. If you're comparing the S4 vs the S4 pro (US SGS3) then its pretty hard to say the battery sucks when its got more power! Of course it will run hotter haha.
I think they could put back the throttling limits a bit though, I think it maybe a battery issue more than anything though so maybe its a fault... Please test it by stressing a high end game for an hour or so tracking the temps and clock speed, that would be a much better indication.
edit: Seen your reply before me, It wont shut down like that in the real world! If you stress test only one core I can assure you that it will run MUCH cooler, you are essentially testing 2x the amount in the s4 Pro than you are in the dual core varient, in these stress tests it works pretty much 110% each core, in the realworld there will be idle times and switching between cores handling different threads, lots of variences that should mean it would be ALOT cooler all the time even if using all 4.

1 core likely won't generate as much heat, and not to mention the whole point of the cores is to distribute load and operate at max efficiency rather than less cores at max.
I understand that some people have issue with the throttling, but until people report that they can't play x and y after z minutes it is a non issue. It may have to do with the glass, maybe LG battery. It is possible the throttle is there to preserve the higher recharge cycles LG Chem batteries have.
Unless it actually ruins an app experience, on stock rom and kernel, it is not an issue. If someone would rather pay 400 more to boost their bench by 5% that's up to them.

Mhmm, I guess it won't be a problem in real world usage. Nevertheless it's quite weird that the phone heats up that much AND THEN SHUTS DOWN, expecially in comparison to other phones like the SGS3, where this problem doesn't occur.
But yes, I didn't hear any complaints about critical-heat-shutdowns in real world usage, so maybe I'm just overreacting. But at the moment it's winter in USA and Europe, so let's see how the phone performs in summer heat
My old HTC Desire often overheats and shuts down on hot summer days when I'm using GPS or playing games, so I just hope my next phone won't have this problem

Mine has been shutting down due to overheating at least once a day. I've just exchanged it so will see how that is.
Worryingly, I will often be doing nothing other than web browsing or similar which should not stress the CPU

[Q] 38 to 42 degree temp is normal for z1 ?

Hello friends...I just bought my Xperia z1 yesterday. I have updated it to 2.257 , with normal usage of 10-15 mins continuously the temp rises to around 33-35 and when i use Camera for around 5-10 mins even, temp rise to around 40 degree and with a game like subway surfers the temp rises to 42-43 degree ... 43 was the highest i saw so far...
Is this ok with this phone ? Or should i go to service center ?
I am using the premium cover i got with the phone, with that on I don't really feel the hotness in my hands but just want to be sure that this is normal heat up with this phone and my phone is not bad..
Also, when the phone is at 43 degree, should i stop using it and allow it to cool ? or should i keep playing the games , use the camera and all...
Any application that can help reduce the heating ? and any better camera app u can suggest ?
Also, please don't suggest to root..I do not want to void the warranty but after 1 year I will definitely root the phone and use custom roms then...

what's the ambient temperature, its its under say 18 then yes i would be worried about that temp, if you ambient is say 25 then maybe not as much of an issue, check the back is the back cover (secured by tape) separating?
If its hot to the touch I would RMA that device

Ambient temp is around 25 only...the back cover just realized is separating from the top end camera side only.
I heard from some friend that If i go to the customer service regarding this heat , they will only say that it is normal as there is no warning message being popped in the phone about overheating.
And at sonymobile.com every one is saying that this is a normal heat up in z1 and on high gaming this temp will even rise to 50+ and there is still no issue except that the battery will drain faster on such temperature. I don't really understand why such heat up is being considered as normal in this phone...I mean it is heating , i can feel it..there can be some h/w issue arise in future coz of this

The explication for the high temperatures, i think, is because the phone is sealed (water proof and all) and the heat can't be very well dispersed in this case. That's why, on Z, many users complained that their phones overheated so much that the adhesive would loosen up (from the back cover) compromising the sealing proof of the device.

This is not always true. Most phones usually do not use any kind of air cooling. There are no fans or even any channels for air to move through in any phone im familiar with. Some phones (GS4 i think?) now have a water loop to transfer heat to the case more effectively, but they pretty much all just use the case to cool down.
When i first got my Z1 i had charged it to full then began using it right away while it was still warm from charging. After about an hour of running every benchmark i could find i started to use the camera on its max setting for maybe 20min before it said something like "temperature is too high, closing camera" (i didnt check the temp but i was a bit warm lol..). I was plugged in for all this usage so i was putting out near maximum heat.
I wouldn't actually be worried about the phone temp, i think this is just the reality of having this beast of a quad core with the standard (very little) heat dissipation. That said i know the CPU/GPU can handle 60-70C no problem, but i would prefer to keep the battery temp below 50C if possible.. Edit: actually the battery health indicator was reading "overheat" and i was at 39C° according to battery temp. I was playing an online game for about 35min.
It would be cool to have a battery discharge widget to show you how much more power is used when all cores and GPU are running, i think some people would be surprised.
The phone should stay cooler if its not plugged in during usage, i think. Also, i'I've never gotten the phone that hot since and im not trying to keep it cool at all.

I use Current Widget it works fine and has a log to file function:
https://play.google.com/store/apps/details?id=com.manor.currentwidget
The phone easily draws over 2 Amps during 3DMark, I guess maximum peak current will be around 3 Amps for some scenarios.That is a lot! Current Widget detected a battery voltage if 4,11V which means a power output of around 8 to 10W peak.
This is on the border of what can be passively cooled in this form factor. Actually it's a marvel of engineering to squeeze so much computing power into a smartphone. And you are right, there is no active air cooling in phones, I have never heard of water Cooling in a handset either, do you have a source? Sounds interesting but I can't believe it
I totally agree on the rest if your post though! Don't worry about heat, the device was meant to get hot, this big 3000mAh battery is there for a reason too. I don't know why so many people get crazy over this, Sony does usually know what they are doing and if they think a high temperature limit is fine, it is.
By the way: In the Nexus 5/ Z1 comparison thread the reviewer stated that the N5 got hotter than his Z1. All modern Smartphones do get hot, it is the tradeoff needed for high performance.

Wow 3 amps i wasn't expecting, but that discharge rate would be required to kill it in an hour. Still nuts, they have defiantly pushed the limits of passive cooling here which disappointed me a bit because this will effect the maximum overclock. I don't know what i need the OC for yet, but thankfully i can just drop this phone in some ice water and it should do over 3Ghz no? My mytough4G went from 1Ghz to 2Ghz so we can expect a 100% overclock here too right? (I don't think the battery could even draw power fast enough..)
And water cooled phones amirite? I was really excited at the water cooled phones, but its not a big deal yet. That NEC probably barely runs cooler, and our Z1 would destroy that cooling setup anyways.. Its almost like they need to increase the size of the new devices to dissipate more heat. Although I'm still a fan of microscopic black hole cooling. Yep, a small singularity should do just fine.
So for now, its ice water and a PS3/BT controller lol.

I really liked the black hole part
Yes just filling the heatpipes with water is no real water cooling, but it's nice to see some innovation. I'd rather like to see vapour chamber heatpipes like on modern graphics cards though, but without any heat sink that would useless too.
You are also right with your more size for better cooling theory, it's no wonder that Snapdragon 800 SoCs are just used in 5" and above devices. That's why I am so impressed with the Xperia Z1f (aka Z1 mini). If I am correctly informed it uses the same SoC as the big Z1 in a 4,3" chassis. That's an amazing feat and the first time a mini variant will be as fast as the big one (unlike S4 mini and One mini). But it will get throttled a lot more than our big Z1s I guess.
Edit: When going for some serious overclocks I would advise you to turn down display brightness completely, that should give you some 0,3 to 0,5 Amps of extra current

I understand your POV but as long as it is affecting my phone, it's integrity and one of the main features for which i bought it with a premium price and a safety measure has to kick in in order to stay everything "ok" like "temperature is too high, closing camera", I'm not so sure about giving it a pass so easily.

However if you leave your device in the sun (car dash or w.e) it can get much hotter then it would from normal operation and when you try to wake the device it will usually immediately power down saying "high temp" or something. This is often the only way you would see this message imo. Pretty much all androids do this, so it really isn't specific to the Z1. An apple device would do the same thing etc.

Absolutely, no arguing.
But I don't agree when this happens while I'm playing a game, while (maybe) other apps are running in the background (multitasking), while wifi or 3g on, with more than 50% brightness level (not to mention maybe plugged to a power supply also to keep the battery from draining). In this particular case, on my old HTC One X, the overheating issue caused 2 burns on my phone's display (but that's another story) and i have them ever since.

So have you actually experienced any shut downs or warnings because of heat? Or do you just want to make sure that there's no problem?
I have been playing a lot if games and used the camera, so far everything seems stable, I have had no problems yet.

Mine reached 60 yesterday while playing dead trigger 2 but the CPU still scaled up to 2.15 so I guess the phone can take up to 65/70 degrees but my hands can't...

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Google Pixel 2 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

Gets a bit warm, not over whelming, about the same as my Nexus 5X

While it gets a touch warm - even when it was downloading and installing all 150 apps, 15GB of Google Play Music, with Folder sync doing data transfers it still stayed much colder than my Z5C ever did with a couple of minutes use. That would probably burn toast!

I thought it got pretty warm, but idk. The material might have just transferred heat to my hand easier because my hand was sweating and you could see it on the back of the phone.

The phone gets REALLY hot when its constantly downloading something.

Anyone got any battery temps? If I run games for an extended period I end up around 43C. Cooler than my Moto X Pure which would hit like 47C.
Idle and light use around 30-33C. The phone has never felt hot to me in any circumstances so far.
"Feels kinda warm" isn't a very good measurement.

If anybody can provide heavy load or gaming temps I'd appreciate it. Also any additional info such as case or no case.

Usually if u charge and use a device at the same time that's when things get hot pixel 2 got warm enough to feel threw a tough spigen case wile browsing and charging nothin crazy

Hmm not great. I came from a note 7 which was very warm to a note 8 which was ever so cool. Considering the pixel but the heat issue among other things is a right turn off.

it will not get as hot as your note 7. note 7s had a few of them explode which just goes to show that sometimes the phone would get hella hot. not a lot of them did so it wasnt a huge problem when referring to how many blew up vs how many were sold but i presume higher than avg temps on all of them

It gets hot sometimes even when you aren't doing anything.

No heat issues so far. The best example for heat is to use Hangouts video calls. Generally with every previous phone I've owned I got a massive battery drain and heat when using FHD video calls. With the Pixel 2 the difference is huge.
We have to consider that this phone is easily ramping the big cores to 2.45Ghz and still maintains a good temp. I'm not suffering temp throttle like I was used after 5 minutes or more of continuous usage/browsing/etc.

It only gets warm when charging. I did not experience any kind of extreme heat coming from the phone and im a heavy user.

Only gets really hot when using AR, not so during games

I havent found anything to overheat the pixel 2 and im a heavy user. BUT that would be a lie. ****ty snapchat can make it warm up sometimes and well, Ark Survival really heats it up and eats right through my battery.

Pixel 2 Hotter after CreamPie update
My Pixel 2 is warmer than usual since the update. Prior to the update, it heated up a couple times mostly due to crappy game apps, which I removed.
Now it gets hot under various circumstances like running Android Auto, which is currently unstable until they release an update to fix whatever they did to break Android Auto.
It also gets warm in my pocket. I'll notice it's warmer, pull it out and cant see any reason that would cause it to warm up so much. This Pie update is crap.
Dont upgrade if you havnt already. At least wait for them to fix the bugs in Pie.

Could you test CPU temp and throttling using this app? It would be really useful.
I usually set it for just 5 minutes and it's enough. Also, tick the boxes in settings to show cpu temp and share a screenshot. Thank you!

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Razer Phone 2 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

I just got my brand new Razer phone 2, and for general use like browsing, you-tube , social media it gets hot at the camera area ( CPU sensors says sometimes between 35-45°C , when gaming it goes up 55°C or maybe more ) I know it has a glass back so i don`t know if it is normal or not?

Played PUBG to test the phone. Set Razer Game Boost to 2.8 Ghz and the phone does a fantastic job of simply becoming warm all-over, instead of getting any hotspots.

I only play DC Legends, haven't noticed any hot spots, and general heat is very minor, but of course its not an intense hardware demanding game...
Edit: for other general usage, Youtube streaming, Pandora, etc., haven't noticed anything worth mentioning either, minor heat, no hot spots.

I run a spigen case on mine and even after long sessions the phone never seems to get too hot and I play games like xcom and pubg.
In cortex I always set the games to the max settings

I'm playing Clash of Clans and this is making my razer phone 2 too warm! And I don't even have a case. yet!

Impossibly hot
I bought a Razer phone 2 last month and it stays cool when just browsing the internet or watching videos, but as soon as I play any games like PUBG or Brawl Stars the phone gets too hot to even hold. I don't know if this is something that I should contact Razer over but it's ridiculous. Not only does it get hot to the point where it is physically uncomfortable to hold, but the touch screen becomes glitchy and I'm practically unable to use it. I was completely baffled by how a phone who's main selling point was gaming and advertised a cooling chamber got hotter than any phone I've ever been through playing the exact same game (Galaxy S5, Galaxy S6, Galaxy S7, Galaxy S9).

Je ne joue que sur DC Legends

heat and obvious first question
I don't honestly put this phone down much throughout the day and I do have a silicone case, yet I don't notice much in the way of overheating unless it's charging. Not advisable to use resource heavy games while charging anyway. But even then it's not excessive.
My question is have you stitched the performance profile in Dev options.
Which then leads me to my noob question, if that profile is altereed does it take precendence over the cpu speed options in the booster app or is that what the app changes if Dev isn't enabled?

They're different options so neither takes preference over the other. The profile in the Dev options controls how early the device will start thermal throttling while the game booster app controls actual CPU clock speed.

Freezing Temps & Vapor Cooling?
I live in Minnesota and it's winter, so temperatures can sometimes drop to -40°.
Extremely cold temps made my HTC One shut itself off and report way less battery charge until the phone warmed back up to above freezing. And my LG Stylo 5 screen will gradually stop responding to touch if it is below freezing temps for too long. My concern is whether extreme cold has an impact on performance, especially considering the vapor cooling technology, what happens to the Razer Phone 2 if that vapor chamber is frozen?

Hi sir i've same issue with you but its the opposite, mine is so ****ing hot because even its rainy season but im live in tropical so temperatures can sometimes up to 40°.
of course my phone so easily raise the heat, cpu can up to 60° hot and battery can be 50°
Im even to scary to touch it when device becomes that hot. now i already buy a cooling fan from memo and it quite helps but find another issue because it uncomfortable to hold if put on to the device. i just wonder is case razer arctech really can make the phone more cooler like some few people?

Heat is so minimal when using the phone but have tested video extensively or gaming. Heat is nearly non existent in other tasks. I think it is actually a bit too low when charging. Seems they have the charging throttled to keep the battery temp under 100°F which limits charging speed slower than it cloud be.

My exynos variant have a high temp at idle and load. Soc idle min 42, normal uses 50-58celsius, max soc temp is 68c.
Antutu scores after loop.
1.run 540k
2.run 520k
3. run 460k

My Exynos is cold in idle, cold in web browsing and warm while playing ragnarok mobile

It heat like a hot fry pan. While using phone normally. if i get call. I can't even touch is to my cheek. Sometimes it feel it will burn my skin.
With my Note 9 this heating issue was even more worst. Due to overheat. I wasn't able to use camera more than 10-15 minutes. Camera app keep stopping because of overheat.
Worst phone brand. Even after having so much innovation. Samsung Note series always disappoint me.

The only time I notice any heat build up at all is when it's on a wireless charger. Charging with the 25 watt included charger there's no heat at all.

When using Camera and try all options , different zooms , Device starts heating and gets to an abnormal temperature , this is affects the 5G signal , as it disconnects the 5G recipient automatically and turns to LTE !!

In my testing, the "Exynos" Note20U is not heating up like the previous Galaxies.

My SD version gets a bit warm just from normal tasks. And my battery life is atrocious :/ I really like this device but I may need to contact Samsung about a replacement and see if I got a defective one.

Exynos version at 120hz, a bit over room temperature screen off, warm when in use and hot when taking pictures. My note 10+ and oneplus 7t pro were never this warm. I'm also getting pretty bad battery life.

Note20 Ultra 5G 512GB Unlocked/Sprint
All around quite warm, charging, viewing, hotspotting.

UHD60 capture definitely gets the transistors in George Foremen mode if you catch my drift.

For mine, heat issue seems exacerbated by being on 5G signal. No heat when on 4G LTE / CDMA Only mode.

Edit:
Forgot to add that it does warm up a bit in mobile data even when usage isn't high.

Strange. Having used notes since the first, i must say this is the coolest phone ive had. By cool i mean temp - avg cpu is low 30°cs, multiple runs of back to back antutu only got me to 37°c - with performance varience less than 3%.
It didnt heat up much when charging, editing 108mp files, or 4K/60 recording
Of course this is SD 865+ (N986N South Korea), not exynos like my older notes.
But so is yours. Like Jerry Rigs, may be urs has graphite cooling.. I wonder if some phones (like SK version) have the SD chip with copper cooling = which would be the perfect combo...

Note 20 Ultra Exynos990 heat Up so much. I don't understand what samsung is doing with exynos.

Snapdragon HK version here. No heat whatsoever. I am not playing games. The screen sometimes gets just warm when I use extensive tasks (camera, youtube, etc). CPU temperature always below 40C.

UK Exynos990 from official pre-order, so bad in heating and battery life. Warm normal use anything slightly CPU/GPU intensive make the phone as hot as a fry pan.

Note 20 ULTRA 5G 256GB "Exynos" - mine seems cool most of the time. Haven't been able to make it hot even with gaming or using camera.
Seems huge improvement compared with Note 8 in this area.

Wow are your temps still that low? How about when wireless charging? I have the South Korean version too and I hit about 40c when wireless charging, and a lot of times it just sits around 35c when doing normal tasks.
