[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 LG Nexus 5X 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!

Phone heats up more than you would think since it's the 808 CPU. It's not super hot, but after like five minutes of hard use, it gets warm. Then it slows down as the CPU underclocks.

Remains cooler than the N5 in all scenarios and heat is dissipated more evenly through the device.
The lower internal and skin temperatures come at the expensive of decreased performance due to thermal throttling.

I notice mine gets a little hot under normal non game playing use, seen it get to 100F.

The top does get warm at times, but mostly extremely cool to the touch

Never had an issue with heat with a few months of use. Only time I've noticed it is when I'm running backup or restore in TWRP.

Compared to my S4 this is an ice cube. Maybe because I have the Ice Blue? The sim card holder in the S4 was starting to separate from the motherboard because of the heat!
It's gotten slightly warm a couple times sitting on the bed or a similar not well ventilated area but hard use and gaming doesn't make it boil. I've never been concerned about the temperature of this phone.

Occasionally gets hot in the pocket for no apparent reason

Phone does heat during multitasking 1 hour Skype call and heavy application of online betting and 1 more application but it does cool down automatically. Still love this phone

sorry

Gets heated while playing games, near Camera!!

My phone really gets hot after some ROM installation and few Boots up whithout resting. Around half top front and rear gets so hot that I can´t even make a call and I have to let it cool to keep using it as I´m afraid it would explode :S. Also performance has an impact when it gets hot obviously. LG, make some work with the cooling because this isn´t good.

My current phone heats up while using mobile data, quite hot actually, how does this phone do?

Mine gets hot when using Wi-Fi tethering and charging.

The website notebookcheck tests for thermals and had this to say about the 5x:
With idle temperatures of just over 25 °C, the Nexus 5X hardly heats up noticeably in idle mode. The handset is also unexpectedly cool under load despite the relatively strong SoC. The hottest spot measured reaches just 37.4 °C here - other premium smartphones often surpass 40 °C. The review sample can even shine with the lowest rates compared with its rivals.

Considering human skin temperature is around 38 degrees C, the 5x remains much cooler than most other devices. It still heats up, but it will be a few degrees cooler than other devices in all scenarios.

I've found the phone fine under every condition other than gaming.
The phone seems to suffer from not being able to dissipate heat very well with it being plastic. I've seen CPU temps get up to 47 degrees Celsius and seemed to throttle and affect gaming performance.

I think the reason is playing an elaborate game.I believe the native android by Google is no problem at all.

I read many reviews and Anandtech analysis of the problem, I was still shocked by how bad it is.
Just install two apps and scroll a bit in Spotify and the big cluster is throttled, holy hell this Snapdragon generation is a complete clusterf**k!
Snapdragon 801 is a lot better.

iam coming from a s801 phone (oneplus one).
it produced the same amount of heat during heavy usage.
i was not surprised after i had setup the 5x first time
s810 is way worse, s808 is actually ok.

Always stays cool exept when you are recording 4K or Slow-mo video.
and even when it turns off big clusters it still feels snappy to me .

Temperature on my oneplus 3t

Hello I've been with a 3plus oneplus three days and I feel like it gets very hot. Then, I give you some photos of your temperature at rest. Using it rises up to 50 degrees easily.
I notice it gets very hot around the camera area.
It is normal? Are these values ​​normal?

Considering the performance of the phone and your skin temperature around 37 degrees Celsius, it's doing a good job keeping a max of just 8 degrees over body temp. ?
Especially considering normal CPU temps on desktop computers maxing out somwhere around 80-100 degress with passive cooling ?

Well, since it's designed for you holding the phone in your hand, instead of mounted on a motherboard with a huge copper cooler on top, temperatures above 50 degrees can feel a bit sweaty (unless your in a polar region or Swedish winter, in case it's just nice and warm on your hands ?).
Ambient temperature and load plays the biggest roles when it comes to phone temperature.

Hahahaha, okey bro, understood, thank you very much, you are a crack, lol

I hope so...it was very unnerving! I had to take it out, reboot and let it sit for an hour or so.
It's happened about four or five times before, each time when I was carrying other phones so I thought perhaps there's something trying to communicate between them (either NFC or Nearby devices) and checked them all.
This time though it was the only phone I was carrying!
Anyway, love the phone and next update I'll refresh the full software. It's just that it got SO hot....!!
Let's see.

Phone overheating issues

HAS ANYONE NOTICED OVERHEATING OF PHONE MOSTLY WHILE CHARGING, GAMING (should expect some heat not this much). I play PUBG on smooth basic plus extreme with no AA and gfx lower settings. Still phone heats up. FAN seems to be a marketing gimmick too. Circulation of air is v poor.
My question is can this be fixed via twrp custom rom tweaks. I'm willing to experiment.

Excuse me. Are you one of those geniuses who charges his phone while gaming?

I think nubia have fake temp status.
Or is that a bug i don't know
When i turn the fan on at max speed. Temp increased. Things like that happen. Or when i come back to auto from performance mode. Tem goes up.
Which is weird. Makes me believe that all this temp and gpu turbo and fan is a gimmick.
Air temp is 26 deg Celsius.

How do you measure the temperature? Was it a temperature of the CPU or the battery?
If your sentiment is not a user error or a fluke, then your unit is defective. Here's what one of the most prolific Youtube reviewers said about the fan - "it was keeping my phone 8 degrees cooler than my Samsung." I assume 8C, not Fahrenheit, because the reviewer is from UK.

Instead of admitting that you were sold a defective unit and exchanging it for a working one, you think there's a conspiracy that involves the Nubia corporation and "paid youtubers."
But hey, I'm thinking this guy is not a psychopath. Maybe it's just a user erorr.
Maybe he thinks that having a fan in the phone should make the phone feel cool to touch during gaming.
Maybe he simply doesn't understand that the fan may be lowering the temperature from 55C to 47C, and that 47C will still feel hot to the hand.
Hey guy,
Can you actually provide real world numbers with screenshots?
No one has experienced anything like this before, so either your phone is defective or you have a nervous breakdown.

Yes, the phone overheats while charging but if you switch on the gaming mode to check heat also in certain Celsius comes down gradually and quickly in my case. So fans not a fake gimmick. Also when you are playing games heat is normal for heavy graphic 3d rendering titles like pubg, fortnight I play pubg with extreme HD and it heats but the fan keeps decreasing the heat. My suggestion is to charge where there is air free flow of air like a fan, AC, or cooler to keep ambient temp in control.

Yes
That is understandable, but then what is the fun of a fan gimmick when you need additional external air circulation with AC.
Even with clash of clans. Not much demanding game phone heats up. Plus additional charging while playing the temp increases continuously.
Circulation of heat and cooling inside the phone is poor. I'm starting to wonder if the battery has nay issues of heat while charging.

Low iq behavior? Projection much?
You are the one who's playing games while charging the phone, something that should not be done to a cellphone battery especially with 26C ambient air.
You realize that by charging and playing you are heating up the battery and the cpu at the same time and that's really going to cut battery's life real quick?

Apologies for the mess. Was relyed on Google voice without proof reading. I have edited now.

I'm not suggest to plug in a charger while gaming, it will make the phone hot, especially when you using the original fast charger. Anoher thing is you hae to know you can't get a high performance with the low temperature, if you get a very hot phone, the cpu will running in a low clock speed. The RM3 can get highest score on Antutu so I think the fan is doing something.

I agree the fan is going something. Had the circulation been a bit effective i think it could have been utilised in a more better way.
Anyways i was just charging the phone while gaming to test the heat limits. Not actually doing it.
Still i have noticed battery heat while standby charging

Anyways i was just charging the phone while gaming to test the heat limits. Not actually doing it.
Still i have noticed battery heat while standby charging

If you are using a fast charger, the battery will get hot, that's normal.

I guess i have to stick with it and just cool it down every after 1game of pubg..

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 Samsung Galaxy Note 20 Ultra 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!

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.
