I have four Xperia z5 compact, now all overheating

UGLYDOLL — Mon, 12 Sep 2016 21:56:48 GMT

Ever since the latest update, all four of my Xperia z5 compacts (one in each color) are now running much hotter and slower. Forget taking quick photos of children... Or typing quickly on the keyboard ,
Two are from Hong Kong, two from the UK.
What's happening Sony?
(I have a 5th one from Japan, docomo version, and it's fine...most likely because they are so slow to update, so it's still on an older build number).

The 253 update on z5c needs to be fixed, I had zero heat on this phone before.
Sony, do you plan on fixing this?

Does the same happen to the fabulous four also in safe mode?

mines is the same with overheating too much, battery life is extremely bad etc.etc. etc. I really wish people would stop asking if it's the same in safe mode,it has nothing to do with it and yes its the same in "safe mode" it's the recent upodate that has messed up the phones and it cant be fixed until another update has been brought out which will probably be next year.

Sorry but I have to correct you. Safe mode is a great way to see if something abnormal is running in the background as in that mode no autorun occur, basically only the needed services are executed.

If you have a single app running and keep crashing or its stuck the cpu usage will remain active and will provoke decreased battery life and the cpu may overheat. In safe mode, unless you run an heavy and cpu intensive app, for normal usage should not drain too much battery nor heat too much. If then the device, instead, overheat and drain battery also in safe mode you can safely assume:

1) it's the os, corrupted and need a software repair,
2) it's hardware and you need to contact local support.

If during safe mode, hopefully, everything run smooth then it's time to reboot and doing app hunting searching the app that is disrupting operations. Finding the right app can be tedious so many users prefer to do a software repair anyway and to install one by one every app they used to have and checking for problems with battery and heat.

Do you see now the importance to do things step by step?

again its nothing to do with safe mode or apps, its the recent update of the OS which i have already repaired and does not fix the problems, there are lots of threads all over the place regarding this issue. I know you're probably trying to help but its really frustrating having a phone that is unusable and someone says "have you tried safe mode" when there are loads of threads and people having the same issue because of the recent update, it brings nothing to the table at all.

Thanks

Same issue. This phone really is bad to the core. Any idea if there is an app that can limit the cpu or the hardware without rooting? Stamina mode helps slightly but the no vibration for my notifications are a hassle. Hope sony can look into this asap. I always fear that it will be like the exploding samsung galaxy s7.

When will Sony respond re: Z5 compact heating/ battery drain

UGLYDOLL — Wed, 28 Sep 2016 08:40:42 GMT

Hello sony,

worldwide, everyone who has Xperia Z5 compact now has to deal with poor battery life and huge heat issues whereas before the last update there were none.

When are you going to address this?

The device is only one year old..., is this going to happen in one year on your new releases?

Instead of remaining silent we would appreciate somebody trying again to your devoted fans here on your official website.

( and no this is not isolated incident so please do not ask me to do a repair or some sort of reset...

I have z5 compact in every color color from various Parts of the world and all 4 all have exact same issue, as does pretty everybody else here, with the exception of your Japanese docomo customers who are far behind with the update cycle)

I'm sorry to hear that

When the phone gets warm and uses more battery than normal, this is usually caused by something running in the background using cpu, gps, data etc. Without more information from your phone i'm afraid it's hard to say what it could be. If possible, could you take a log from your phone and send this to me and i'll forward it internally to see if it can reveal the cause?

To do this:
Settings > About phone > Build number, tap 7 times on the build number
Go back to Settings and select Developer options and turn on "USB debugging". Then tap "Logger buffer sizes" and set this to "4 M".
- The next time you notice the phone is slow and has been using more battery than normal:
Settings > Developer options, select "Take bug report". When the report is ready (may take a minute or so) you get a notification that you can tap and share to Google Drive. Please send me a link to this file in a private message.

After taking the log, could you also try what @YoGem suggested? With safe mode you can test if the cause is something in the phones firmware or if it's caused by a downloaded app.

I am experiencing a lot of heat and my phone becomes extremely slow when I'm using it more heavily, like Pokemon GO. After a few minutes of playing all the faster cores are shut down, and the 4 little cores are running under 1 GHz... Of course this means I experience very poor performance.

Is this normal? Or should I return my phone? Is the Z5C not capable of running such "heavier" apps by default? I cannot try these things out in safe mode...

Also I have tried running the Antutu benchmark and it gets much better results if I run it while it is cool, if I run it again right after the first test the result is a much lower score. Can you please confirm that this is ok and this is how the phone is expected to work?

I use a phone for calling the pizza store or pranking Buckingham Palace, and I use my laptop to play games.

Mine overheats while texting, browsing or even watching 480p videos on youtube with NO background apps and most apps disables... Oh and as everyone thinks its a miracle solver, the same happens in safe mode

I am using my Z5c for almost 1 year and in last months, it started overheating after latest program updates. It's model is E5803 and os is Android 7.0 and when I check the software status, it says it is already updated. I do not play any games or watch movies using my phone. In my case, the problem starts when I activate bluetooth. It starts overheating and battery life decreases rapidly.

Sadly.... I think that Sony has given up on the Z series... It's evident that the 810 cpu has always had problems with getting hot, but throwing Nougat on top...It's too much.

Sony don't and will NOT respond to the battery/heat issue...

As they can't fix it.

All they can do is cut the Cpu power, to prevent ...which is doesn't...sorry...try to control the heat issue..

The z series is now a great mobile-if you don't use it.. (that was sarcasm)

And for those out there on the forum who still think the heat and poor battery life issues are not a problem... I ask you to go out and borrow a phone from another manufacturer for a week ... then tell me that 4 hours screen on time in 24 hours is good! It's terrible!

All this talk about doing a clean install, safe mode, clearing cache... it shouldn't be necessary.

I just wish Sony would hold their hands up.

There has been a confusion regarding processor cores. And any info on this hasn't been proved that it's true that cores r made inactive. But the processor speed got underclocked to 1.5 in N which was 1.9ghz in MM.. Onto my observations.. Only 5 cores r active..inwhich fifth one comes into play only for few secs to minutes when we put the device under stress!! BUT this isn't the effective way to deal with the heat produced in the device.. MM HANDLED IT BEST WHEN IT COMES TO CAMERA AND VIDEO AT HIGHER TEMPS IN WHICH 6 CORES R ACTIVE AND CPU WAS CLOCKED AT 1.9 GHZ..

Yes!! It's a shame that Sony made this device par below a mid range..im afraid if this trend continues in future devices and users like us wil.be. Left with no choice except to go for ios or some other more reliable brand ( Nope! Not Samsung).. Im sure that Xz premium wil also hit this criteria after 1 yr of its release.. Mark my Words _ Xz premium isn't an exception for this... I used to deal with Sony devices from.x10i days to z series.and I has been the successful victim of this.trust me.. U pay for a high end device and u endup with a mid range device at the end of software support!! I don't care whether they consider this post or not... since commercial marketing and software assistance r completely different departments.. But this will make it to their list of recoveries or -to do list-at the end of the day. Regards Sony!!

Over heating my xperia Z5

My Z5C overheats when I browse this forum. It's unbelievable. This needs to be addressed. It's not hard to release a small CPU speed downgrade as an update. Performance would suffer a small downgrade (20% of the time), while resulting in better performance most of the time.
