Power is not an issue in Z5, rather not so tuned rom... I think... Getting random freezes then restarts when multitasking, my gf Z2 has allso problems on 6.0.1. Freezes ocasional, does not restarts.
[Xperia Z5 Real Life Review] sirdoha:
It's very fast when using Xperia Z5. However, Sony has blocked/ disabled/ lower some "peformance and speed" of Snapdragon 810 to enhance the battery and reduce the heat :( That makes multitasking on Z5 is not very impressed :rolleyes:

On Marshmallow update, overheating was improved but still jump to high temperature fastly due to powerful SoC.
[Xperia Z5 Real Life Review] nathansg7:
In brazil (+/- 30ºC / 86ºF ambient) the phone easily overheats when opens for a long time third party app camera (ex. snapchat) or heavy games (ex. gta sa)
[Xperia Z5 Real Life Review] Hnnryyb:
on mexico in a city with normal temps of 30-35 on (sometimes winter) alost all year, or 45-50 in summer and i since have it since december it doesnt really over heat(jsut heat that much that you cant hold it)that much 4 to 6 times in all the time i have it
[Xperia Z5 Real Life Review] prince10t:
depending on the app used, I usually get 40-55 C from normal browsing and social media apps to extensive gaming like asphalt 8. I live in Philippines which usual temps are ranging from 28-35 degrees celsius. CPU Temp by mooncake is the app I use to monitor my temps.
[Xperia Z5 Real Life Review] indianmeister:
45.3 °C max for me since MM in 3d gaming as reported by Battery Monitor Widget, 30°C in sleep mode avg
[Xperia Z5 Real Life Review] corvintheus:
Unusually heating and battery drain

My phone unusually heats up without any reason and battery drains like almost 20 % in standby in 1 hr.This doesnt happen everytime though,I checked if any background apps were running.But its normal like FB ,Whatsapp,Album etc,.The back side on top of the phone gets heated
[Xperia Z5 Real Life Review] josephnero:
Rev 4 here no overheating or anything.Cooler than my Galaxy Note 4 and previous Z3
[Xperia Z5 Real Life Review] Lptrex9:
İn turkey

37-55C ıf ı play games be 60C and more :/ ı think too hot
[Xperia Z5 Real Life Review] Phazonclash:
A lot hotter than my Note 3 and OnePlus One, but it's bearable.
[Xperia Z5 Real Life Review] Abaddon:
the temps are fine. the same with my 6p.

the hottest S810 device I used was the M9 then the Oneplus2.

the 6p and the z5 is on par when it comes to heat. so good job sony. :)
[Xperia Z5 Real Life Review] Vaizen:
I'm planning on upgrading to a Xperia Z5 but this thread makes it come to my mind... does the XZ5 custom kernels have undervolt features? In my experience undervolting makes phones cooler. So is it possible with the z5?
[Xperia Z5 Real Life Review] _LLJY:
Short answer : no and the z5 doesnt need it. Long answer: The Z5 has AVS or auto voltage scaling(similar to the 6p) thus, it makes it very hard to implement undervolting. Androplus kernel used to have undervolting, but it was completely broken and does nothing to the voltages. AVS scales according to load and frequency. Therefore, if you are using your phone with very light use, it should not scale the voltage up and heat up the phone.
[Xperia Z5 Real Life Review] galtom:
Guys, thanks for those informations.

I am about to get new phone and (untill now) Z5 was my first choice.

I had Lumie 920 in the past and I did not like how hot it was getting.

I do not play games however I browese web a lot,use FB, Spotify, etc... - will I have trouble with temp?

I now own lumie 640 - it does not get hot and it has awesome battery life (even under W10m). As I need Android phone and Z5 has decent battery and camera I was thinking it might be a good swap... (plus waterproofing, etc). Not so sure anymore :(

Is this the problem for Z5 Compact as well, do you know?
[Xperia Z5 Real Life Review] SovPanda:
My z5 heats up while charging, you can feel the top half of the phone starting to heat up. Today my z5 went crazy trying to watch a video on a site that works on my z3,m8. The whole phone froze and started burning it was weird, previous days I would notice it heat up doing daily things. You'll definitely notice heat if you haven't had issues before with a previous phone
[Xperia Z5 Real Life Review] galtom:
Lumia 920 was getting really, really hot.

Especially during navigation in a car. Screen on, software (Here Drive) running, charging on and sometimes sun through the windshield.

Do you guys use Z5 in a car? Is it not turning off because it is too hot? That would be a bummer....
[Xperia Z5 Real Life Review] nreuge:
No problem in my car up to now.

We'll see this summer...
[Xperia Z5 Real Life Review] galtom:
Ok, got Z5, id does get quite hot (yes, during navigation as well) but I can live with that.

Plus I have it in see through cover so it does not feel as hot to touch. But to be honest I am not impressed. I was expecting it to be cooler.
[Xperia Z5 Real Life Review] Furtzy:
I use google map yesterday and charging in same time, my Z5 was so hot that it won't charge properly and continu to drop battery with a quick charger.
[Xperia Z5 Real Life Review] FYLin21:
I almost never get above 50 but it does feel pretty warm to the touch after a long period of use, even just browsing with poor signal. I think it's actually hotter after 6.0.1
[Xperia Z5 Real Life Review] irock_you:
I just bought the z5P a week ago... in Saudi Arabia.... in the middle of a scorched summer (55C and rising next month) (-_-)

my only issue was with the camera overheating.

I managed to resolve the video recording overheat issue by keeping it in (Full HD 30fps) and using the internal memory.

Also, I reduced the screen brightness down to minimum while recording. I recorded 30+ minutes without any issue

I didn't test the 4K recording yet tho...

One more thing.... don't use Snapchat... snapchat is bad, Mkay. It blew up my LG G4 and pants rear pocket after keeping it running in the background! and when I used it with the z5 it almost did the same.

Here's a screenshots from the phone with the temperature right after I stopped the recording

[IMG="cpu-z Z5P"]http://tinypic.com/r/30bi4d0/9[/IMG]
[Xperia Z5 Real Life Review] rolo143:
My battery reaches about 40 - 46° when on heavy use while gaming (ex. playing Need for Speed No Limits for an hour or so... ) Then I leave it idle for a while and it cools down

Btw my battery drains about 20% - 23%in an hour while playing, is that normal? (Playing NFS or any other high-graphic game)
[Xperia Z5 Real Life Review] stipi69:
Heats less than Z2, but then Z5 is better in gaming, so this should count as improvement i think, couple of days my gf's z2 didn't allow capturing video anymore because of the awful heat outside, my z5 managed to do it, when z2 cooled a bit it worked fine later on
[Xperia Z5 Real Life Review] sirdoha:
On the UK, in Winter, the Sony Xperia Z5 is a very useful device. It keeps us warm without turning on the fireplace. Haha

However, in the summer, the camera is just like a hot barbecue, too hot (for me) to handle it, especially when records 4K video!

P/S: Bought the Z5 Dual Sim on Nov, 2015
[Xperia Z5 Real Life Review] cocagenda2:
i cannot agree more :D i also sad that to my friends that i can warm my hands in winter and cook some some eggs in summer...i think xperia z5 is the only phone with that kind of ability. :laugh:
[Xperia Z5 Real Life Review] DarkGuyver:
The problem with Sony's Xperia Z line of devices is that they use a "Premium" glass and metal sandwich construction. With the glass panels acting as a insulator keeping the heat in the device and the metal frame acting like a heatsink draw heat away from the SOC. This combination of materials used in a device's design is what makes it a very expensive handwarmer. In fact all devices that have the same "Premium" construction suffer from the same overheating problem.
[Xperia Z5 Real Life Review] _LLJY:
A warm phone actually means a good thing, it means that the phone is properly dissipating heat. Some phones may feel cooler but the Z5 runs really cool(even when feeling warm) it runs from 45-60c over clocked which aren't high temps at all. In contrast, my mi3 and Redmi note 4g both felt cooler but were always pinned at 60c

---------- Post added at 05:57 PM ---------- Previous post was at 05:56 PM ----------

Why don't you try out the Z3 or Z3+ ? Both could roast your own skin playing games.
[Xperia Z5 Real Life Review] DarkGuyver:
But it could also mean that your device is producing way too mucn heat and is having a problem dispersing it.
[Xperia Z5 Real Life Review] EQ2000:
I am quite perplexed at how 4k recording could heat up modern phones so much. For example my Z1 with 4k mod and same Mbit (55Mbit/s, steadyshot enabled to counter shakyness) at ambient temp of 25 celsius after 5 minutes battery was 40 and CPU was 60 degrees. CPU usage was about 70-80% across all 4 cores and the CPU never went above 1Ghz (goes upto 2,15GHz at full load). That is on the SD800. SD810 should be able to do the same with much less CPU usage thus it creates a question mark why it produces so much heat with what should be low to moderate workload.
[Xperia Z5 Real Life Review] _LLJY:
The reason why the SD810 is so hot is because of the rushed move to 64bit. The ARM cores don't play nicely with other parts of the SoC so it heats up more when doing certain workloads. This is even worse with kryo on the sd820, although no heat issues but several parts of the SD820 are partially broken(parts like the DAC). Also the architecture of krait is different from the big and little cores and as such CANNOT BE COMPARED TO EACH OTHER(the same load may not produce the same amount of heat)
[Xperia Z5 Real Life Review] EQ2000:
So in other words the SD800 beasts the SD810 and SD820 for stable 4k recording/encoding. :cool:
[Xperia Z5 Real Life Review] _LLJY:
Yes :p
[Xperia Z5 Real Life Review] Ranjhazhj:
My Z5 premium is getting heat while playing Marvel Contest of Champions and Marvel Future fight and other High definition games, is there any solution to keep the CPU temp level down while playing games? BTW I'm living in Saudi Arabia where normal day temp is minimum 45 degree and at night it reaches to 30 degree around 2 - 3 am.
[Xperia Z5 Real Life Review] _LLJY:
It's normal for the SoC to get hot
[Xperia Z5 Real Life Review] silencer51:
New Z5P owner here, upgraded from a Z2 that is still going strong. Yeah, the phone heats up, especially when you 're charging + using it heavily. I haven't encountered any severe throttling issues so far, and I mostly take stills with the camera, so 4k video shutdown after a few mins is a non issue for me. The Z2 also gets hot under heavy use.

I'm waiting for a Tudia case from Amazon and I'm thinking of doing the 'copper foil' trick when I get it, has anyone tried this with the Z5/Z5P?
[Xperia Z5 Real Life Review] arismelachrinos:
if u Play with virtual reality,ur z5 might burn itself ? I watched a 3d movie and I couldn't touch it for like 10 minutes. seriously can cook eggs. (not ironical)
[Xperia Z5 Real Life Review] _LLJY:
It's normal for every phone in vr
[Xperia Z5 Real Life Review] stuartb88:
damn you dudes, i had all but made up my mind to buy this phone
[Xperia Z5 Real Life Review] _LLJY:
Heat is a non issue on this phone..
[Xperia Z5 Real Life Review] Vcaddy:
Whaaaat ?! Heat is not an issue ?!!!

I bought the z5 when it was fairly new in the market, rev 4. Gold ( one of the most gorgeous phones ever made seriously ). And it overheats to the point of burning its own screen ( litraly )

Please keep reading this review to the end if you dont want to waste your time and money on this device.

I was using a galaxy s5 for couple years rooted and oc (no heat watsoever), and needed another device to do gps navigation and mirror to my tv etc, at the same time i needed an upgrade and the galaxy s6 didnt have sd card storage so the z5 cought my eye.

Even though the whole internet was flocked with xperia z4 or z3+ over heating horror stories i still went ahead and got the z5 as reviews said the 810 got updated and sony incoporated a cooling heat pipe to disepeat heat.

And DAMN HOW FRICKEN HOT THIS PHONE GETS !! I dont do any gaming at all not even social media, just chrome browsing for 30 mins will make it overheat from 30c to 48+ easily and if you know anything about li ion batteries they discharge much faster the higher the temp and thats with around 20c ambient room temp -_-

The MM update made it a tad cooler but still over heats like stupid. The z5 will reach temps up to 60+ if your using skype and charging at the same time to the point it started burning the upper area of the screen where the heat pipe lies.

Also using the camera ( just veiwing no pics or video recording) will make it over heat like crazy. Never the less i kept using my galaxy s5 for navigation and cpu intensive stuff.

I thought that mine could be defective n sold it for galaxy s7 g930f exynos ( coolest phone ever endless hours of brwosing and the temp stays around 30c and less.

Seriously the z5 is the hottest phone ever and i dont advise anyone to buy it, and reading here that most members are having same stupid temps or even more than what i had makes me sure that the culprit was the sd810 and my z5 wasnt defective.
[Xperia Z5 Real Life Review] _LLJY:
Bruh, 60c in the cpu is nothing, my Redmi note 4G got alot hotter than this phone. In my experience, this is the coolest phone I've used only behind the mi3. With OC and everything, my screen is still fine and no issues here. Mind you, this thread is only 5pages long. Alot of people don't have issues with this phone and most of the people in this thread are just over sensitive.
[Xperia Z5 Real Life Review] galtom:
My overheats too.

I use it (as all my previous phone) as car-nav.

Now, during summer in Europe its not very comfortable to use.

Since it has screen on +charging + sun through windshield it gets so hot, that it dims screen so I can not se the map.

Lumias with Windows never had that problem - only Lumia 920 got really hot, but still did not dim the screen.

I hope it will get better in autumn and winter.

As much as I like the look of Z5 I really would like to see less heat, better battery life and (don't kill me!!!) an option to try to use it with Windows - I really like that system (Android mess is sometimes tiresome...).

But... well - we have what we have and non of the above will change in Z5 (perhaps Sony will fix "tap to wake" option?).
[Xperia Z5 Real Life Review] Vcaddy:
Hey

My bad, i meant +60c battery temps as i stopped monitoring the killer temps of the sd810 before it gives me a heart attack lol.

Anything above 40c battery temps will drain and degrade your battery badly.

I mean that phone was so hot that it made me turn into a smartphone concerned heat-o-phobic checking its heat every couple mins. Took me couple months to get used to the galaxy s7 which usually around +5c from room temp.

For people who are saying thier z5 temps are cool, apparently you live in a freezing climate or you simply keep it inside the fridge :D

-for anyone who wants to put this phone to test:

Try skype for 40minutes to 1 hour if you want to get purple burns on the screen.

- add charging for the recipe if you want to get cool purple yellowish burns :)
[Xperia Z5 Real Life Review] _LLJY:
60+ on battery? Never got that, you have a faulty unit. 70c on the cpu still isn't very high. The SoC can handle temps upwards of 90c
[Xperia Z5 Real Life Review] Vcaddy:
Bruh, i dont want a soc that can handle +90c :)

Socs should be running around 30c idling and can hit 50+ during cpu intensive use.

90c+ ? Maybe Sony should include a liquid cooled case for the z5 :D

Glad your z5 is cool enjoy it bruh :)

[Xperia Z5 Real Life Review] _LLJY:
Every single chip can handle 90c, the limit imo should be 70c. That's where the phone starts to get scalding hot. 50c is very cool
[Xperia Z5 Real Life Review] chinmoy32:
I am using a Z5 Dual E6683 In Bangladesh (Made in thailand) with 6.0.1 , Custom ROM , BL unlocked, modded to some degree, stock kernel patched with RIC off and DM -variety off. I noticed that using TWRP to backup and restore heats my phone the most. I have tampered glass protector installed on the both sides of the phone. The back upper side gets the most heat. It gets almost untouchable during /after a backup or restore session. But it gets cooler pretty fast. Now I have the phone like for 1 week and suddenly i am noticing that it gets some 7-8 degrees hotter the moment I unlock it with minimal brightness and no workload, not to mention i am in my office (DATACENTER) with ambient temperature like 23 degree or less. Used all the available "thermal patches" , none of em seemed to work at all. Once i did a nandroid backup using TWRP on my way home in a NON- AC BUS and it was like the surface of a boiling pan . one more thing i have noticed which is almost all the time only 5 cores are running at some clock speed like 1GHz or lower but 3 cores always stay turned of, why is that ??? i tried to turn em on via working the phone like crazy but no-nothing . and it still gets hot! i wounder what would happen if all the 8 cores were running at full throttle ???? !!!!

Twrp has NO THERMAL PROTECTION. The phone will get VERY HOT when backing up in twrp.
[Xperia Z5 Real Life Review] chinmoy32:
OK, thats understandable.

I have observed another thing , when rebuilding delvik/ART cache the phone gets very hot , just like in twrp.

current status : using .152 LP stock thermal engine with XZROM v3.0 with stock kernal from .253 MM patched with you know what ........

with the settings I tried and played NFS NO LIMIT for about 40 mins last night (during 1 hour load shedding ) with MAX BRIGHTNESS and the device stayed very reasonably warm , like just only 5 degree higher than the ambient temperature. One thing was the battery charge-- it went down 100% from 87% at that time. I think its a good combination so far by my standard.
[Xperia Z5 Real Life Review] OfficialTEC:
Mine gets really hot sometimes, even when my phone isnt doing anything. It starts to burn my legs sometimes and then it just cuts out and restarts.
[Xperia Z5 Real Life Review] _LLJY:
There's something very wrong with your phone

Mine doesn't get HOT much, only when playing heavy games or online games over LTE. And in none of those situations it becomes unusable or laggy.
[Xperia Z5 Real Life Review] vasquez:
Rev3 here, played Asphalt 8 for about 30 minutes, much cooler than the old Xperia Z I had before.
[Xperia Z5 Real Life Review] abraxaz120:
Never bothered into measuring them, but doing some light multitasking will make it so hot that it will throttle to the point that I cannot type, so sometimes I had to put it in the freezer for a couple minutes...

Already sent it to service once assuming there was something wrong with it, but it came back in the same conditions. I guess this phone is not suitable for warm regions or hot summers, plan to get rid of it before next summer, winter is coming so the extra heat is "welcome" haha.
[Xperia Z5 Real Life Review] _LLJY:
I live in a very hot climate and my phone is doing fine. Try Sunkernel and ROMX combination, seems to work great(honestly I don't know how) but my phone's cpu is at 70C MAX in super intense games whole charging. Battery stays cool too.

hot or not actually depends on the users,if you can customize then the heat can be reduced. see the status bar,the heat average just 36°,whereas I live in indonesia and Indonesia has a tropical climate that is hot
[Xperia Z5 Real Life Review] TimCrownie:
I've used Xperia Z5 and Z5 Premium for about 3 years.

The main issue is came from its SoC, Qualcomm Snapdragon 810. That SoC is really hot-depends on its 20nm transistor-technology. Every phone uses it will be really hot, like Google Nexus 6P and OnePlus 2. Some Chinese people called this SoC as "火龙", aka "Fire Dragon".

In my daily use, this SoC often reaches 70 Celsius or higher, sometimes even more than 100 Celsius - enough to boil water.

Sony has used Snapdragon 810 on both Xperia Z4 and Xperia Z5 series, and the temperature control of Xperia Z5 series has been improved, but it is still not good. When I use Xperia Z5 and Z5 Premium to record video, they will overheat and stop recording after few minutes.

After I unlock the Bootloader and remove the temperature control file, it won't stop recording because of overheating; however, the phone itself is getting hotter.
