The phone is no overheat issue, but normal heat is there.
When the temperature reach somewhere, the performance will drop, but this happen to every phones, even PC.

If you are looking for performance, stay at android 6.
The stupid lag issue for android 7.1 was fixed at July/Aug patch. But latest Oct patch is worse performance than before, but still in acceptable level.

Sony & Qualcomm have the best gps signal for my opinion. Usually can lock with 15+ satellite + 30~ standby. While other brands usually lock with 7-9 satellite and 20~ standby.

RAM management is more important than RAM for android. (Of course it only apply when the app is smaller than your total RAM, you can't fill 1L water with 0.5L bottle.)
My nexus 10 (2GB ram) flashed with custom 7.1 rom is much stable (not faster) than my XZ. My Z3 (3GB ram) is still stable than my XZ. If you read XDA forum, many custom roms are faster and stable than official rom. Even just debloat + custom kernel will help on official rom.

I am dilemma to unlock my phone now. Just finish the 1 year official warranty last week, but still have 2 years extended warranty. I am giving chance to Sony fix the system on Android 8, probably will release as soon as next 1-3 months.
If no improvement i will just unlock the phone.

Maybe too much memory in locked + RAM management too conservative.

Blessing for android 8.

If it still suck, i want to unlock and flash sound mod, i missed great speaker from z3 sound mod.

I am using this creator sound mod since z3.
Incredible.

Unlock&flashing need a lot of courages, but do not need much of skill lol.
I prefer the old phone which can expoit root, no need to unlock. Anything worse happen, just factory reset and send to warranty. But unlock is a bit more risky, anything bad happen to usb port or screen, it may not able to re-flash back to official rom and send warranty.
But seem like it will never able to do that, after Z5 series. But luckily, XZ is the last phone which has android 6 rom, which still exploit to dirtycow bug, still able to backup TA partition.
Nowadays new phone doesn't really need root. Official rom is good enough for daily usage. But official rom usually is more balanced setting, which limits the performace and the true power of the hardware.

How to you update it?
OTA or use PCC?
Clean install by computer again.
BTW, this is not the latest version yet.

I am setting my gf xz, still in android 6.0
How smooth was it.

XZP is up with 8.0
XZ probably within the next 2 month.

For me is worth.
But keep android 6 until stable new version come out.

Sony has good speaker & camera, but suck in software.
If you are willing to take risk and void warranty(able to backup), you can flash sound mod to max its performance.

I am looking forward to Android 8.0, received quite a lot good feedback on XZP. Some fixes on camera distortion and sound is louder. And noticeable performance is increased.

Hopefully it can reach next few days.

New update is out now.

No need to surprise.
Basically X Performance, XZ & XZs are the same phone.
At least 90% same.

In XDA, XP share some development with XZ.

Of course some files/drivers are not same.
The version name is same, doesn't mean the file is same.

After few days of Oreo, i very satisfy on it. Super smooth near to 0 lag unless heavy gaming + phone heat up. RAM management is working now, 92% ram usage without lag, unlike 7.1. This is only flagship level performance.

So far, my review is
Performance: 7.0 > 8.0 > 6.0 > 7.1
Stability: 8.0 > 6.0 > 7.0 > 7.1
Battery: 8.0 > 6.0 > 7.0 > 7.1

Overall: 8.0 > 7.0 > 6.0 > 7.1

Do you mean this? I see it still here.

**Opps sorry, i think you mean for the bulk remove. Yes that was removed.

I didn't realize this function is gone. I never clear cache unless low space. Never clear for XZ because 64gb is much enough for me.

I prefer the new oero way, just let it auto.

Average temperature around 40°c for me.

Almost the same.
But a very little slightly warmer than nougat for normal usage.
When high performance, oreo is far cooler.

If you have enough of space, cache doesn't matter.
It speed up your application, loading time, and battery saver.

Non Malaysian unit?
Some regions yet to release.
