As I am still undecided wether to buy the Z5 or look for another option, I'd like to get your personal opinions concerning the heat emission of Sonys newest device.
I have my Xperia Z for 2.5 years now and in my opinion, that phone gets pretty warm too (I play a lot of Hearthstone on my phone) but it isn't getting too hot to handle. I'd hate to look for another option since my Xperia Z was updated from 4.1.2 to 5.1.1 and my hope is, Sony keeps on updating all of its Xperia phones for at least 2 years.
To cut things short: please state which phone you used beforehand and give a number between 1 to 10 how warm you personally think the Z5 gets, 1 being cool and 10 being unbearably hot.
Ive had the Z1 and Z2
Z1 heavy use 3
Z2 heavy use 5
Z5 Heavy use 8
Nexus 5 - 3
iPhone 6 - 2
Xperia Z5 - 8
On my Xperia Z5 i downloaded the game Heroes Charge and when i started the game i got promted to do an update of 200mb. During the time the game downloaded the update on 200mb the top part of the phone got pretty warm. The whole download process took about 1 minute and it was quite worrying that it got so hot that quickly just by dowloading an update for about 45 seconds..
I instantly put the phone back in the box and will return it today. I don't dare to buy this phone for so much money just to experience difficulties in the future due to heat problems.
Mine arrived today - still deciding whether to keep it or not
Was taking a few pics, nothing too strenuous and it got pretty hot.
I dont recall the Z3 having the same issue.
The Z3 have a different CPU, that's why it doesn't get as hot as the Z5.
I'm really worried and havn't totally decided about sending the phone back. I really like the phone but it just gets so damn hot quickly. Is this something to worry about in the long run? I guess i can get used to the phone being warm, but not if it can cause any issues in the long run. I mean, i don't want a broken or really slow phone in six months..
Got to admit, the Z5 does heat up a lot quicker than any device I've used in the past
Z- 5
Z3- 4
Z5- 6
The Z5 does heat up quite fast but it doesn't get "hot" it gets warm and its fine to touch. On my Z3 the battery temp i usually around 30 degrees celsius, whereas my Z5 would average around 35 ~40 degrees celsius. again it gets warm but not "hot." Whenever you push the CPU or GPU the back will get hot, so downloading a bunch of apps etc... will push up the heat and its normal for any device.

So the heat is nothing to worry about? No risk of reduced performance in the long runt etc?

Nothing to worry about, not unless you don't like the device to be constantly warm. It's much cooler here ok Vancouver right now so i can't say it would be around the same temperature for you.
I'm in Sweden, so it's pretty cold right now, around 5-10 C as highest during the day (40-50 F) so a warm phone is no problem, i would welcome it as a heat source when i'm outside
But i was just worried that the performance of the phone would be affected by the "heat issue", i really don't want to spend a lot of money on a phone where i might get issues with later on.
Bad things with overheat I have used Z5 for 5 days now. When the phone is charging it heats up badly and if you browse heavier web pages it starts to lag as does other apps and even launcher. If I run Antutu in these conditions it barely reaches 41000 score. I should mention than without charger pluged in (being colder or in other words regular conditions) it only reaches 50000 score, although, most reviews mentioned 60000 score. So this is my experience and I don't like it

BTW it heats up less because of GPU and more because of CPU usage. You can run 3D graphics for a long time and its not hot. But if you install anything or multitask (i.e. play music, run updates and browse) it heats up very quickly. And I repeat that I have only noticed it while being charged.

Guys, never do CPU intense tasks while charging, that's def going to heat up the device and consequently reducing performance!
As long as the apps don't close because of heat, it's all fine and the phone getting warm shows that the heat drain pipes design is working. The Z3+ closed apps due to heat = unusable. The phone getting a bit warm to the touch is absolutely nothing to worry about. Remember, there's an octa core processor with 3 GB of RAM in that slim device
Based on that input, do you guys see FCs of apps due to heat?
i can tell Z5 is far better than my Z4 (Z3+) in terms of heat. consider heat issue is nvr exists.
Ok, so I have done some more thorough testing with Antutu and temperatures. I have tested the Z5 in room conditions (22 celcius). The device was cold (from standby) and I ran Antutu. Score 50000.
Then I ran Antutu again and again and again. With every test the device heated up and the Antutu score... droped down. It dropped down to 42302 until the Antutu app was "unable to verify" the result (kind of crashed).
Then I put it in a freezer (in a sealed bag of course). The Antutu score was 66609.
A you can see the heating up can redue the Antutu score by as much as 35%.
I believe this answers somebody's question whether the Z5's heatup reduces performance...

You can't really say it's 35% because the high number is when you had it in the freezer. Any phone in the freezer is by definition not a normal use case. Your findings of a 15% decrease is within normal variation for a phone being used constantly, especially when using a benchmark app constantly.
While it shows it definitely heats up, it's not as big of a difference as you make it sound IMO.

Scientifically speaking this is a poor way to investigate the potential heat issue. Your primary concern is the temp and performance of the CPU/gpu, which does NOT consistently correlate directly with the temperature of the phone. In the case of the Z5, you have an actual heatsink combined with materials that are very good at transferring heat. The fact that the phone warms up quickly is actually a testament as to how well it dissipates heat from the CPU.
As for the antutu scores being worse, these scores are only useful so long as they represent real world performance. At the end of the day, you can still record 4k video for 30 minutes. I personally have not seen any slowdown related to heat. Downloading and installing programs does definitely heat up the phone, but the slowdown is because of the installation process and not the heat (in my experience) as this improves as soon as the install finishes.
I have done a lot of stuff with this phone and had no problems with performance, unlike my brothers g4 which can't navigate for long periods due to overheating. Yes the antutu scores show there is throttling, but I'm pretty sure every phone with this chip is designed to throttle to some extent. In my experience this throttling is irrelevant.
Every single core octa core phone throttles. This is my findings from 5 Antutu runs from identical cold starts (25C CPU temp) with all other apps closed on my three phones
Z5 : 62K - 54K (I won't agree with the 50K score he got on Z5 from the cold start, definitely lots of things were running in the background)
S6: 67K - 52K
Z3+: 57K - 46K
In terms of consistency, Z5 tops all of them. Considering the drama we've see earlier on other 810 based phones, this is a miracle Sony pulled on Z5. It could be the heat pipe or sw enhancements or both. No matter what - Z5 puts an end to that 810 drama.
Thank you guys for your answers so far! I took from your answers, the Z5 gets hotter than the original Z and some of you think that that's no problem and some think it's too hot ...
Ambivalence in regard to it's heat emission seems to be characteristic for this phone ... a lot of reviewers says it's ok while at least the same amount of reviewers says it's too much heat coming from the Z5 ... I'm still undecided ...
I've had the Z5 for a couple of days and even during the initial setup when it was updating and installing apps I was still able to use the phone normally and it didn't get too warm. I'm coming form the Z3 and I'd say they heat up pretty much the same - about 6-7 out of 10
Phone gets warm it's true, I remember my z1c going warm also pretty much the same 5-6 in the warm rank, but I tried a Xperia M4 last week and holy crap, that thing was super hot, I had to hold it from the bottom because the heat was unbearable, overall I am very happy with my new Z5, it's a great device
Got my one two days ago and must say gets pretty heated when I listen to music and play candy crush. Spoken to o2 and said that they would replace seeing as am in still my fourteen days cooling period. Am wondering that if I give it time will it change and settle?
Hi everyone,
I'm planning on buying a new phone my budget is not limited but OnePlus 2 checks all the boxes I need in a smart phone? I'm pretty excited to get this phone however when I went online on GSMArena a lot of people were reporting overheating issues and freezing of the phone. Can anyone tell me if the phone overheats on latest stock OTA as of 14th Feb because I really want to buy this phone in the coming 2 or 3 days.
Thanks.
No. With stock thermal file you could have poor performance on HQ games after a while. If you changed it you can avoid the a57 cores to turn off or under clock a lot. I play real racing 3 30m+ without underclocking (for temp reasons) 100mhz. With stock freqs for more than 30m+ ( I don't continue playing so I don't know how many it will take to underclock). I use thermal extreme file with 3°+. Of course it gets hot. But no problem for me, all phones gets hot while gaming or under heavy tasks, I can live with that. My nexus 5 gets hotter and quicker. Also I played vainglory for almost 2 hours and no undercloking either.

You should be fine I've had this phone for about two months and id say at best it gets warm when gaming the only time its ever got hot was when i was in a very hot room with the sun light hitting the phone but i was playing a driving game for 1 hour plus at this point so fair enough that it did get hot.
But id say 100% of the time when im not gaming it never gets hot im on stock 2.2.0
For just going on facebook and normal apps it never gets warm even most games it only gets sightly warm at best unless your really hamming it for a long time it will never get hot. you'll be fine for £289 you really can't go wrong i love this phone once MM is out and full dev support it out going to get even better!
TL;DR: can overheating affect life of phone?
Hey all! I previously owned a lg g3, and it used to overheat as well. After about a year or maybe year and a half, one day when getting hot it rebooted and then wifi/Bluetooth stopped working.
A few forum searches suggested the chipset warped due to the overheating over time. I haven't actually opened that phone to verify but makes sense.
So as we know, the camera throttle issue got fixed on the Moto g4 (at least the camera works flawless for me even when overheating to 120F). But my concern is less the camera performance now and more so the life of the phone after constantly overheating. (I have kids so I'm constantly using video / letting them play games, so it's overheating once every day/two days)
The chips are rated for very high temperatures - like 90C internal. That would translate in something like 70C external, you cannot held the device at that temperature. What you are calling "overheating" is actually normal temperature for this kind of electronics, it doesn't affect the functionality.
But sure, things can and will break sometimes - regardless of the temperature. I would use the phone intensively while in warranty period, if an electronic part is to fail, is more likely to fail at the beginning of device life.
Hello, I just bought an S8 as an upgrade from my beloved S6E+. when I firt turned it on the phone was on 55% I started using smart switch to transfer stuff from my old cellphone over WIFI (over 10gb of stuff) while the phone was updating from the playstore and downloading a software update and updating galaxy apps (too many stuff) I felt the phone getting really warm then it became HOT not uncomfortably but very very noticeable.,I downloaded an app to see the temp. and it reported 59 C for the CPU and 42 for the Battery. then it jumped to 69C for the CPU and 47 for the processor. I waited till everything finished, updated the sofware and reststed. it idled at 42 - 45 C.
I live in a hot country and the outside temprature was 38 C. but my S6E+ never reached such temperatures, and I don't want to bring any drama but the whole Note7 thing is making me paranoid about using the phone while its hot like that. so is this normal??
1. The fact that you're living in a hot country matters. Its a factor. Coz apparently ambient temperatures affects the feel of materials such as glass or Aluminium. So take note of that.
2. You've said it yourself,you made the phone go through a hell doing stuff all at once. Let it settle. Give it days,maybe weeks.
3. If after all that you're still experiencing the overheating,then it could be;
a)Just a software hitch which could be fixed by a simple factory reset or software update.
b) If someone else report the same issue,then it could be a common issue with the phone
c) If no one reports similar issue and yours persist,then you probably have a defective unit,and you should consider replacing it.
I've been running benchmarks on this phone.
I've noticed a couple of things.
Thermal throttling on this phone starts at a very low threshold and is very aggressive.
Supposedly the maximum frequency of the large cluster is 2.45 GHz
At room temperature my phone never reaches that performance.
Here is a copy of the thermal-engine.conf, pulled from system/etc.
As soon as you start to benchmark the speed starts dropping:
At room temp I get Antutu ssores in the 130-150K range.
If the phone has been in a very cool room I get 160K numbers.
If I put it in a very cold environment for a few minutes I can get numbers in the 178K range.
Back to back runs plunge performance.
So it does not surprise me that the phone freezes at times.
Not happy that the phone throttles like this.
I have also found that if the phone gets to 44C then the throttling is so bad that a LG G4 or Samsung Galaxy S6 will outperform this phone.
So the thermal-engine.conf has this phone crippled.
This is speculative, but I wonder if overheating was the cause of the release delay. If so, perhaps this was the workaround they implemented to get the device out. That said, if throttling is the culprit then it could explain why my phone runs like an Evo3D much of the time. Generally before use, it's in my pocket, which is body temperature and the phone is always warm. Maybe even pocket-temp causes throttling?
Oh well, return initiated yesterday, awaiting response from CS - I just can't stand to take a chance a potentially crippled device. While the updated did increase the responsiveness of the screen a slight bit, I didn't see an overwhelming change that put this in the category of other devices running similar hardware. Back to the OP3...

So the device won't get really hot.
It won't even get that warm unless it's charging.
If you put it on a charger, it will be throttled after about a minute.
If I run Antutu and start out with the device sitting on a table in a cool room (too many conditions), I can get a score of about 167K.
If I sit it on a baggy of ice, I can get a score of about 177K but never unless the device is artificially chilled.
But if you run Antutu back to back or GeekBench and look at the temp, as soon as it hits 43C, you hit a wall.
The device won't heat up more than that but it's now running only slightly faster than a 6P and slower than a Pixel XL or Moto Z.
I don't want to pay $850 (yes that much if you include the extended warranty and tax) for a marginal device.
If I had root, I would have played with the thermal-engine.conf. It can't be right.
You go from full performance to half in a matter of 4 degrees C.
I have looked at other files for other devices and I've never seen anything that aggressive.
Even the 6P was not that bad.
I have an iPhone 6s (work) and no matter ho many times I run the test I always get about the same numbers.
I have my phone charging and I ran the test and I just got 115K. So on a charger the performance is 65% of max.
This is why I'm sending it back. Might as well be a LG G6.

Good to know, and thanks for the thorough diagnostic! Even with rooting and changing the throttle configs, I fear a voided warranty and bricked phone if it's a design flaw and not a software bug. It's just not worth it for me to wait and see when there are other new and shiny things just around the corner. *squirrel*

I'm pretty sure it's a mistake in the thermal-engine.conf.
I actually contacted them and submitted my information.
You don't throttle from 39-40C down to 50%
I've worked designing chips for better than 25 years.
If the 835 is more efficient than the 810, then there is no need for anything that aggressive.
Anyway, I asked for a RMA and they are sending a the boxes/envelopes.
No cases is a big deal for me also.
Since I'm already at $900 for the phone and camera (taxes and insurance). I might as well give the X a look.
Yeah, it costs more but if I'm already at $900 another couple of hundred isn't going to matter.
Unfortunately, I have to go back to my LG G3 since my 6P was sold and shipped last week.
