When I bought Xperia T, after a while, I started to be a little disappointed with performance, autobrightness, discharging when playing, etc.
After some digging deeper into this problem, I have found, that cpu is throttled by temperature. And not only the cpu.
A few minutes of playing game, cpu goes to 800MHz, display brightness goes to level 100 (max. is 255), wall charger current is reduced (even when connected, it is discharging), radio power is reduced, etc.
Change it yourself:
Example:
xo_therm 14 -1000 380 20 NOTIFY CAM_NORMAL cpu_perflevel:1728000 charge_current_limit:0 usb_current_limit:1 modem_level0 lcd_brightnesslevel:240
xo_therm 14 = sensor step
-1000 = -100,0°C
380 = 38,0°C
20 = don't know (maybe some kind of sample rate?)
NOTIFY CAM_NORMAL = obvious (camera)
cpu_perflevel:1728000 = cpu frequency
charge_current_limit:0 = obvious (0 is 1300mA I think, 1 is 1100mA, 2 is 900mA, etc.)
usb_current_limit:1 = obvious (has impact on charging too)
modem_level0 = power of modem
lcd_brightnesslevel:240 = obvious (0 - 255)
Set the highest temperatures, with low enough frequencies and charging current values, to let phone cool down.
"gpu_perflevel" can be used too and there are some other thermal sensors in sysmon.cfg, which are also responsible for thermal throttling.
Disclaimer:
Each device is different and I am not responsible, if your device burns with some values from here.
Both CPU cores always on:
Echo 1 in /sys/devices/system/cpu/cpu1/online and change permissions to 444. And if you want to prevent errors from log (and maybe some unwanted wake locks), rename /system/bin/mpdecision to something else or delete it.
what is temp at what cpu throttles (and other things)?
seems it is lower than other devices, something like 40C, i think my sgs3s was at 76C or similar.. not sure, will check later.
sgs3 was a very hot phone.

You can see the temperatures in sysmon.cfg - xo_therm 400 500 = 40 - 50°C for example. Cpu temperature, not battery. There is no tool to monitor cpu temperature, but if you set your own frequencies, you can see with Cool Tool, how long it takes to the lowest frequency.

thanks, will check. i am on cm10 and didn't notice throttling yet, but i will check now as it is ****ty if so.

I have noticed the throttling but it doesn't affect the performance in my case, playing games and watching HD video are fine, just annoying when the screen suddenly does dim.

@OP:
If you don't want throttling, uninstall Androids inbuilt Thermal monitor(No need to tell you the risk by doing that I guess).
Thanks for you valuable advice.
Don't think it would help as that file says 2nd core off values are hardcoded

I think, that it works, because I tested it and I am using my own values.
Good thing I won't be playing games when my T will arrive

Still? Damn how long do they take ? -.-
Here is the .apk of the old version. No idea how much works and what doesn't!
Hello,
Could it be some kind of default on your device ? or maybe the application ?
Cause I remember Qualcomm's communicating on their S4 being "cooler" than its opponents when under heavy load.
Can someone else confirm ?
What's strange is that the game you mention (Osmos HD, which I bought some time ago for my TF101) does not even use super high end 3D graphics etc etc ... maybe the perf drop could come much quicker with some cpu/gpu intensive apps.
If confirmed, it might even become a big "no go" on this phone for me.

I've had this phone for a while now and I haven't had a bit of lag while playing any game I have. Everything seems fine except the sudden dimming of the screen when playing games. Don't let this put you off buying the phone, its a great phone
Edit: been playing Osmos HD for at least 25 minutes, I'm experiencing no such lag or performance issue. Only the dimming issue I seem to get.
Well, after some more investigation, I have found, that lags in Osmos HD are not caused by cpu throttling, but wifi disconnecting.
Playing the game is fine, but still, with default settings the temperature is going high and except the screen dimming, cpu goes to 800MHz, (1 core disabled on highest temperature), and phone is discharging even when connected to wall charger.
It seems to me, that the overheating is not caused that much by cpu, but gpu. It would be nice, if it could be tested somehow by lowering the frequency of gpu.
I wonder if the heating issues could be fixed with software patches. Given Sony's desire to incorporate playstation stuff, I find it hard to believe there is some sort of hardware issue.
Wish we could get some more samples to work with.

Just measured with my settings (in the room - about 23°C):
10 minutes of playing Osmos HD without charging = 62°C CPU temp
With one core running on 1350 MHz and LCD brightness value 150, it's not increasing anymore.
When charging, the temperature will go higher. I will test it too.

Have you tried treppn profiler?
Anandtech says a CPU core draws around 450-750mW while gpu goes 800-1200mW!
Seems like 400mhz is a hard Task for an 225.
If you are still on ics maybe try jellybean? Perhaps project butter may more efficiently handle the gpu.
Maybe even make a list of "stress test" for people to try and see what the various results are.
If all else fails try undervolting the gpu and cpu.

Yes, I tried trpn profiler provided by you, but there are limited options.
It looks like the GPU cannot handle this frequency.
Undervolting won't help anything, but lowering GPU frequency would help I guess. But this cannot be done without custom kernel, allowing this.

Same here. I've been playing Speedball 2 and GTA3 mainly but I have played a few others too and haven't experienced any lag and no performance issues observed at all.
Hello guys!
My Razr i sometimes is so warm, I installed an application to see the temperature of the battery and when I'm not doing anything it's 29-34°C (84-93.2°F) and when I use facebook, listen to music and surfing the internet simultaniously the temperature increases to 38-41°C (100.4-105.8°F) What I know is that batteries must not be exposed to temperatures higher than 40°C (104°F)

What do you think, if your theory sustain, how could people near equator get along with mobile phones? The max temperature for Li-ion batteries is 45 degrees C when charging, and 60 degrees when discharging (use).
I can't be the only but has anybody noticed the phone overheating quickly with moderate gaming or even an antutu benchmark. This is without X mode. When I do the same with my K20 Pro, it doesn't overheat like the Rog Phone 2.
How are you defining overheating? The device throttling? Do you receive overheat warnings?
Just because a phone gets hot doesn't mean it's performing worse. If anything it could mean it has better heat dissipation due to better contact between cooling and cpu. I play dual screen 2 games at once for 3 hours straight and the cpu remained cool around 40C. I kept my cpu speed down because it was overkill anyway

Can feel the heat near the upper left of the back of the phone. Temps were in 40s.
40s is not overheating at all. ROG phone has higher surface temperature than some phones but it's because it's barely throttling even after 1 hour of gaming. No need to worry

Exactly, it's not overheating, it's doing its job. It's moving that heat away from the internal components and to the outside of the phone via the vapor chamber, external vent, and aluminum side body section near the vent. Throw a slim case on the phone if you don't like feeling it warm in your hands, or tweak the game mode profiles to underclock the CPU and GPU and/or lower the thermal limit during games that make it heat up too much in your hand.

Agreed. It makes perfect sense that the t6ip left is getting warm, that's where the vent is
Rog phone 2 tencent edition overheating and shutting down
My Phone overheats and shuts down when under heavy load, or while charging while im sleaping. it first happened while playing pubg mobile and streaming my game to youtube. I can feel it gets very hot and after a while it just switches off. i also tried the antutu stress test and when it reaches 5% it switches off, i opened the armory crate to check the temps while antutu was doing the stress test and saw that my cpu reaches 73°c and then again it switches off. this is with xmode off.

That's definitely abnormal. You should try to get a replacement or warranty repair.

any updates. i’m having the same issue.
Same here. When I play games like ML or any games my phone overheating fast then my screen will turn off ..and another issue when I charge my phone while overheat my phone will shutdown
does anyone knows how to fix this?:crying::
I'm having the same issue. Charging overnight - it gets really hot, and sometimes it'll randomly reset. Not gaming or running much in the background. It happened since the last update prior to the most recent
Keep in mind that Rog phone 2 has a SnapDragon 855+ and + means it's overclocked. While other normal phones out there runs on default speed settings. So that's probably why Rog phone 2 can get hot quickly due to it's overclocking.
Mine gets very hot along the edges. In fact it gets so hot along the edges that it burns my fingers. CPU temp doesn't ever go much above 45 but the sides become untouchable... Is this a feature designed to stop you playing and thus save the phone from melting in your hands? ??

I had this problem on Android 10, but the problem was reduced when downgrading back to Android 9.

Yep android is a dealbreaker. Extreme overheating cause of the software.
After long time and intensive research, I found the real problem which is cpu/gpu refusing to throttle while on load. Usually the system reduces the clock speed of the cpu to keep the temperature between acceptable working range (room temperature - max of 60°c)
If cpu doesn't throttle, the cpu temperature rises until it reaches the max (i.e 65°C which is critical temperature as per A10s updated thermal framework) and shuts down the device.
I found a workaround which involves reducing manually the clock speed as the temperature increases.
But it requires tasker app(paid) and root to work.
Hi everyone,
I recently bought an S23 Ultra, after installing various device info apps (devcheck - device info HW - aida64) I realized that the Cpu temperature reaches 95 degrees in a moment ...
I put in screen sharing an app info and geekbench6
Do you think it is normal or a defect of my phone?
I add some screens.
194°F at idle? That's way hot even under load.
What's display brightness at? What's the ambient temperature? Battery temp?
168F tops is all I would go for the CPU, maybe 186F but that's pushing it for a smartphone.
Find out what's using all the power and tone it down. Don't count on temperature throttling or auto shutdown to save it from a thermal runaway. It may shutdown and never wake back up...
If the device is hot to the touch, shut it down, power it off. 140F is the top limit for the battery and that's too hot. With a full charge on the cell it can degrade it permanently.
Room temperature : 24 degrees
Battery temperature does not exceed 42 degrees.
That is the CPU Temperature during geekbench6 with cpu running at 100%

I wouldn't bench it if it's running that hot!
Lol, if my battery gets above 105-6F I shut it down.
