Dex2oat keeps heating the phone to the point of thermal limit and it keeps the cpus at 100% here is a screenshot 10 mins after boot.
Thermals indicate 85 celsius

I see my CPU works on 40-50% in idle mode without turning on applications and stuff. I also noticed that the frequency is varying constantly and onle 2 cores are ON, the others are stopped. I think that all of the cores should work in similar frequencies and the CPU load should be around 10%.
Let's see what is the CPU work of the others......
Just installed the app. All 4 cores are active but they seem to be sitting around 300mhz jumping up to 1400 or 1190 as they cycle.
29% cpu load.
Running BBS tho, 300mhz is where my phone sits most of the time and the cpus have no issue going into deep sleep.
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
In nougat roms temp stays at 33 to 35 at normal usage but in oreo roms temp always reaches to 3 9 to 41 in normal usage why so much deference
sorry, can't verify that:
which kernel? and which governor?
you've spent 61% of time at 1400MHz, so the temperature is not a surprise.
Use NOS or use init fix processes of Gabriel kernel. There's something is non fixed in Oreo is ramping up the CPU which causes the heat and battery drain.
(some rom has internet and charging heat too)
A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
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.
