CPU Thottling WEIRD... - Sony Xperia XZ Questions & Answers

I am using XPERIA XZ since 2 years and last 1 year i guessed after 8 update CPU Throttoling sometimes.. The problem is not about sd820 is about sony is so agressive with tempature even at 49-51 celcius degrees cpu is decreasing clock speed and cant go higher clock speeds at this degress i know that 49-51 degree pretty normal for mobile soc.
My phone is rooted and on stock firmware + omnirom android 8.1, i also install that mod using magisk https://forum.xda-developers.com/xperia-xz/development/xz-xc-fsc-improve-performance-reduce-t3675981
But overall nearly same..
Whats the solution.. i feel like i am using half power of sd 820 sometimes...

The mod won't work on omni or any other AOSP-based ROM since they use another HAL. I've checked thermal-engine on stock ROM since Android 7 -> 8 and there's no change in threshold and value limitation for CPU. I also have a thermal mod for AOSP-based (I made one for stock and posted it) but don't care to share it, if you wanna give it a try, tell me.

[Q] overheat problem

I have GT p6200 running Carbon ROM KitKat 4.4.4
And since I updated room ICS I've been having this overheating problem
When I was on ICS the tablet didnt get hot while using WiFi
But when I moved to KitKat I started facing this problem
But if it's not the WiFi could it be the CPU governor ??
Now mine is set on user space
If so what's the default CPU settings for this ROM
Thnx

This is your 3rd post you have posted as they all happen at the same time on the same rom i would have said all of them on the same tread as
Post 1 http://forum.xda-developers.com/galaxy-tab-plus/general/battery-drain-kitkat-t2835925
Since I updated to KitKat 4.4.4 carbon ROM
I've been facing battery drain while using WiFi mostly not during sleep
I tried doing everything I could to stop it
Disabling Google play services from time to time... Using greenify
Freeing up ram ...battery saving mode
Disabling wake up for apps from app ops
Now I use it for 2 hours and it uses 40 percent of the battery with the lowest brightness though
Please give me suggestions or fixes
Thnx
Post 2 http://forum.xda-developers.com/galaxy-tab-plus/general/wifi-toggle-stuck-t2835929
I'm using carbon ROM KitKat 4.4.4 and the ROM is really smooth and great except for this problem that showed up lately
Sometimes when I turn on WiFi it get stuck and totally freeze until I reboot the device
Is there a way to fix this
And I use xposed modules by the way
Could they have an affect ?
I only use greenify, clear recent apps, clipboard and XAD modules
Thnx

Post 3 Default CPU governor settings for this ROM is on demand
Looking at Post 1 & 3 Both of these have to do with the battery Heat
overclocking generates more heat but under-clocking generates less heat (i have not extensively used this feature but asking in the dev forum or if Google'd the governor settings of the ROM might help to see what it does)
high battery temp you less battery capacity e.g 4 amp becomes 3.2 amp BUT low battery temp more battery capacity e.g 4 amp becomes 4.8 amp
also motherboards like to be cool 50 degrees F to 95 degrees F or 10 degrees C to 35 degrees C this is the ideal working temp
anything more or less than that would cause a waste of either performance and/or battery capacity
my tab has worked from 11 degrees through all the way to 60 degrees C battery temp please note i live in South Africa i go to cold places and it gets really hot some times so use these values as only a rough indication
my tabs idle temp is 15 to 25 light work 25 to 35 gaming 35 to 40 degrees C this is a thumb suck of my normal temp can be more or less (just pulled my tab out of my pocket 23 degrees C and while typing this sentence increased to 24 degrees C currently it is 8 degrees C 81% humidity inside a building )
can i ask that you post your battery temp? as temp is relative (i am using antutu benchmark x widget that displays temp and batterylogger)
also the heat could/maybe be causing your WiFi to get suck not on or off
please see it changing the govenor fixes this

Anyone had doubts between: Xiaomi Mi4C & Asus Zenphone 2 (and can share)?

Hi,
Curretnly i'm on the G3 and i dont like it much.
Thinking on 1 of these:
Xiaomi Mi4C
Asus Zenphone 2
Now, I asking that in Mi 4C Thread bc's i thinking that there is some people that might had this.
What do you think?
Thanks!
It comes down to preference really as I dont really like phones bigger than 5" and xiaomi is quite established. Its got the right size, ir blaster and a good SOC which should get good rom support, cm12.1 already available
Where are you based? The Global version of the Zenphone 2 has band 20 which the Mi 4c doesn't have (may be able to be unlocked manually but I'm doubtful). The Zenphone also has expandable storage which the Mi 4c lacks - you may already be used to this and the larger form factor due to currently using the G3. That said, I've heard (but cannot personally verify) that the Zenphone has erratic battery life and performance in addition to being more expensive than the Mi 4c.
ermacwins & wingsfortheirsmiles,
I got used to 5.5" so this is not an issue at all...
I from Israel and LTE bands are 1800 & 2600.
So from my understanding, both of them would work, right?
32gb are more than I need, so the expandable storage is not too important.
If the Zenphone do has erratic battery life and performance, it's a good reason to go for the Mi4C, isn't?
Anyone else suffered or heard on it?
Thanks very much!

Well, my Mi4C had battery drain. Around 3%/hour on idle with WiFi and 4G all off, so when I woke up a third of my battery was already gone. I ended up fixing it by flashing the international ROM but after that, I've been getting 5 hours of SoT which is great. Can't comment on the battery of the Zenfone.
Regarding the battery problem:
Looks like it could different between your's to anyone else.
I read a review in a site in my country and the person who made the review praise the battery life.
Thanks!
My Mi4c has very good battery life. The same like the z1 compact i had. Other phones i had i charged sometimes more than 2 times a day.
The zenfone 2 has worse battery life, build quality and performance. If you don't mind the SD card and 5" screen then the Mi4C is your phone. Zenfone 3 could be very interesting when (should be kinda soonTM) it gets released though!
Thank you all!
Go for the Mi4C.
P.S: A newer model of Mi series also coming soon?
How abt Redmi note 3?
No battery issue with my Mi4C. Left it idle for most part of the day with cellular and Wi-Fi connected the whole time and managed 0.7% / hour idle time. I also have many apps installed (not facebook or any messaging apps though). It's rooted and greenified, running original stable Chinese Miui 7 Rom with some Chinese bloat apps removed. It's also scoring 52K on antutu 6.

Processing power wise, ZenFone 2 (the high end 32 GB internal memory with 4 GB RAM model) is comparable to Mi4C, the GPU is even slightly better. However, when it comes to video recording, ZenFone is waaaaay below Mi4C. The still image, if you use latest firmware, is already fixed though. Note that due to the use of Intel processor, some apps that use native libraries might not be installable. Ensure your apps are architecture-neutral or have both arm and intel version available.
OTOH, Mi4C has thermal issues and I still can't find the best thermal configuration so far. This causes the cores, both CPU and GPU, get shutted down or their upper limit is decreased to lower down the temperature. I break this limit by changing the limit a little bit higher, but if you play games while charging the phone, my best record reaches 90° C. Hot enough for a sleep killer tea
Happy deciding!
Having owned both phones i can say the Zen2 is a dud. The screen is dim, the speaker is weak, some apps drain crazy battery as they are using an ARM emulator to run on x86. It wobbles on the desk and the battery dies after your lunch break. The camera has low exposure that makes everything look darker than it is. The Mi4c just works like you expect a flagship to do.

I dont believe in 90° C unless your phone is borked and termal throttling doesnt work, also phone would shut down anyway with that temperature.

It is, well the screenshot I have is 87 actually in one of the many thermal zone (they're all varying from 60 or so) but during that time I did see and feel 90 (as a hot tea drinker, I know how hot is 90). Thankfully I have a flip cover that absorbs the heat, but if you touch the scree, it's really damn hot. Thermal throttling doesn't work on my device, because I've disabled the thermal driver :cyclops:
I don't really know the actual upper limit, but I guess it should be around 100-120. My PC was 120, but I don't think smartphone's SoC will differ much.

Hahaha, worry not, it's been back to normal temp (30-50). The problem only happens if you play resource intensive games while charging.
My last phone Mi4i also reached ~90°C after playing with the thermal engine. The flashlight turned on in the pocket of my pants and burned for half an hour. I just noticed it because my leg got hotter and hotter luckily the phone wasnt damaged through this. Also, i think the CPU can handle these temperatures without being damaged, but i would worry about other phone components such as SD Card, battery or glued components
Sorry, my antutu 6 score for my Mi4c was 685xx, not 52k.

Antutu scores

Hi everyone,not sure if the subject has been discussed before or not. I tested my E6653 variant of the Z5 today on Antutu and was rather shocked at what i scored. Now i know Antutu scores arent a true reflection as scores are variable depending on device temp,apps running etc etc. But i am still at a loss becaurge the best my device scored was 78000. That is a whole 20000 lower than what Antutu says the average score is for the Z5.
My device is unlocked and rooted. Im currently running it on Mrom v2.4.8 with the default kernel for the rom. I have played around with the kernel settings by changing governors etc but with no better than the 78000 i scored. My question is,how do i get a better performing device without sacrificing any to little battery efficiency in the process? Does anyone maybe have any insight into this as i feel my phone greatly underperforming with the current setup.
Not sure if it's relevant, but my Z5C (7.11 stock rooted with Magisk) managed to score 95K in latest Aututu:
CPU: 31886
GPU: 35768
UX: 21834
MEM: 5176
Click to expand...
Click to collapse
Mods I installed to help improve performance:
Green Kernel (For Z5C exclusively, pretty sure there is alternative around this forum)
FSC V5.1 (Very balanced thermal mod)
Brevent app (Eliminate bloated background processes)
Manually debloated (A must for stock rom, using settings app and SD Maid)
Note that 720p and 2GB RAM may effect my final scores, take them respectively. It normally hits 5hrs+ screen on time with moderate usage however I don't play games on my device, and overall it's quite responsive considering the SD810 except for multitasking.
I never liked MRom for how bloated it is at first installation with many underlay modifications that fail to meet my sony experience expectation. When in the worst cast scenario tho, there are always options to downgrade to 6.0 or custom roms.

Moto X Pure Battery Performance and Replacement

So my Moto X Pure only gets around 5 hours SOT and around 2-3 hours playing games. I seen a 3200 mAh battery replacement on Amazon and I'm wondering if anyone has tried it? I'm using the Resurrection Remix OS with my CPU set to power save in the battery options. Please post your battery stats and ROM information so I can see if my phone would benefit from a battery change.

LoL... With your SOT and game times, your battery is holding up pretty well. I would not expect much of an increase from any battery replacement you may get.
Regarding batteries from Amazon, be wary-especially of those claiming more mAh. Typically higher mAh means a larger battery so be skeptical. Based on what I have read in forums and reviews, it seems many of the batteries for this phone from Amazon, regardless of advertised mAh, have been hit or miss. Some manage to do well for 3 to 6 months then problems start.

I lowered my GPU frequency to 300 MHz that seemed to help a lot especially when playing games my battery doesn't drain as fast. I even lowered my screen resolution to 720p and set my GPU frequency to 180 MHz. The OS is smooth but when I start playing some 3D games you can definitely notice FPS drop so I put it back at 300 MHz. I couldn't increase my battery by lowering my CPU frequency for some reason my battery life seems worse when I try to mess with the CPU. The only thing I managed to do was disable my big cores in kernel auditor when they aren't needed and setting my low memory killer to aggressive in kernel auditor seemed to help my battery as well. That's just my personal experience hopefully someone will get something out of it.

The CPU for the most part does pretty well scaling up and down based off processing needs. You probably just don't have CPU intensive apps so didn't notice much. You notice the GPU while playing games though. I think for the most part setting to a lower resolution might help with games at lower frequencies on the GPU in terms of maintaining higher fps at lower frequencies, but a 5.5 2K screen with simulated 720p probably doesn't net much battery life in other usage areas.

Right I am able to keep my GPU on power save and it'll sit on 180 MHz and the OS is still smooth on 720p if I bump it up to 1080p I'll have to put the frequency at 300 MHz or else it'll lag. I noticed when I move through the OS the GPU will jump to unnecessary frequencies like 300 MHz or even 450 MHz. Keeping it locked to 180 MHz while using Firefox or watching YouTube helped a little bit. The main problem for me is the lack of kernels to choose from. I used this tutorial https://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557 to tune my CPU governor since the Nexus 5X has the same SOC but my rom Remix OS has a feature called CPU boost that I can't turn off unless I flash another kernel. The problem with the Moto X Pure is that it doesn't have many custom kernels. I managed to find one that works with my rom but the camera doesn't work. I could simply go to another rom but they lack the customization Remix has and some of them have SeLinux set to permissive and I don't really feel like dealing with escalation attacks and having my bank information stolen.

Wow. Since I first got the phone 3 years ago, i personally just have had very little time to delve much into doing custom ROMs and kernels for this device due to work scheduling I'm moving to a new job this month and should have more time on my hands. I'm probably going to get back into things.

I'd compile a kernel for lineage based roms with the nougat modem but I'm not that smart I don't even have a computer to do it with lol.
So I went ahead and installed the EX Kernel Manager app and I downloaded the Hawktail governor profile. After doing that my battery went from 2-3 hours SOT to 4-6 SOT from 100%. When I play slither.io on the default CPU setup my battery would drop 10% every 10-15 minutes. With the Hawktail profile it drops 10% every 30-40 minutes. I thought this was incredible because NFC and Bluetooth was still on. I also found that the Alucard CPU governor gave me similar results during my observations. I really hope somebody else can benefit from this thread.
Here is the download link https://androidfilehost.com/?fid=24686679545610694
Remove the .txt extension and put it on your micro SD card or in the ElementalX folder. From the Ex Kernel Manager app go to CPU>Governor Options>Load then load the HawkTail file then click apply on boot.

CPU overheating in some custom roms

hello guys
my xperia z3 has cpu overheating problem in some custom roms. i've checked everything like battery voltage and temperature, cpu temperature and usage.
when i record some 4k videos after 2 minutes cpu reaches over 85 degrees celsius or device reboots while doing it. even while web browsing and watching 720p videos and up, the cpu reaches 75 degrees and up. logcat and last_kmsg aren't helpful to find what exactly causes heat. tried reinstalling the rom several times, wiping cache/dalvik, installing the rom without g-apps or magisk, pulling out simcard and sdcard...
non of those helped me.
these roms are ok without overheating problem:
all stock roms
carbon rom 8.0
lineage os 16
pexorom 1.0.0
these roms have overheating problem:
lineage os 17.1
carbon rom 6.1
the other users of these roms don't have overheating problem. only me!
i've talked to lineage os developer and he said lineage os 16 and 17.1 have same kernel
also carbon 6.1 and 8.0 have same kernel.
now i'm completely frustrated.
note: also the compass sensor died under repair.
guys do you have any idea what is wrong with my phone???
I suggest some steps that help to recover your device from overheating
1.Freeup space on your internal memory and maintain at least 3GB free space on internal storage
2.Remove the tight case that leads to holding the temperature
3.Uninstall rarely used apps
4.Reset your mobile after backup your data
These steps definitely reduce your device temperature

thank you for the advice, but i experience this problem even when one app is installed.
if i install only a camera app after flashing one of those 2 roms and record 4k with it, the device gets too hot.
if i stop doing it, then my phone gets cold. i already tried all of those solutions but they were not helpful.
there's no such problem in stock roms, i can record 4k videos or do heavy tasks for long in them.
The xperia z3 uses the snapdragon 801 , a flagship from almost 7 years ago , that produces a lot of heat and doesnt have the incremental steps on performance that more modern socs have , by this I mean that instead of going from lets say 200mhz doing nothing , then to 700mhz then to 1ghz and so on , it just "boost" into the highest possible clock speed , this makes it snappier but gets hot . With that said , given that you are using a custom rom you could tro regulate this steps with cpu profiles and governors , I think you must have root to use the apps that manage this , but some roms have this controls built in .
You could also try to put it in regular battery saving mode (not the ultra saving mode) this will limit the cpu power draw and may help you if you dont want to do tha manual configuration , turning off gps and sync will help too.
Cheers
