quick question about underclocking and overheating - Xperia Z3 Compact Q&A, Help & Troubleshooting

im considering buying an used z3 compact but overheating pops out here and there on several videos or forums that i read about the phone, my question is is there any rom or kernel that provides underclocking while mantaining the phones performance ?

Cyanogenmod is pretty good for this.
However it is only a nightly - but from my experience they are very stable.
Getting a Kernel like M5 Kernel would also help with under clocking but keeping a relatively stable device

You shouldn't believe everything you read. I've had a Z3c for 6 months now and it's never got hot. All the stock roms come with a temperature throttle that prevents overheating. Sure, if you sit and play games for hours and hours I'm sure you'll feel it warming up, as with all phones. The only time I've felt the phone getting warm is when I use a 'quick charger'.
Unlocking the bootloader to be able to use a CM build is going to damage the quality of the camera and disable some of the other functions of the phone, just so that you are aware.

Once you get the Z3 Compact, install a custom kernel to give you better control options over your phone's hardware. For example you can use better hotplugs and thermal drivers to regulate the phone's frequencies better. Underclocking and using a Battery-saving CPU Governor also helps when you don't really need the power boost. I personally remain at 1.9Ghz with only 2 Cores active at any given time
*Unlocked bootloader is required to use custom kernels, backup your DRM keys before doing so. Also you can restore lost camera function easily, just check the Android Development section

Does the Xperia SP normally can handle all the high end games?

Does the Xperia SP handle most highend- games directly out of the box?
Or it requires some rooting, flashing etc.
I'm going to buy the phone soon..
Any recommendations accepted too..
4.3 [207/205] have ram problems. It fc most games. But in custom roms everything seems be okay. Recently I flashed mokee[4.4.4, ubl] and everything is perfect[battery lasts as good as 4.3 or even better, perfomance much better....]. If you want to stay with stock or stock based rom I didn't suggest you to buy xperia SP.

Well, let me put it like that. Our phone has about 60-65% of the GPU power the latest phones (The one with Adreno 330), our GPU has to render exactly half the pixels cause we have 720p display compare to 1080p. And that's indeed the case. In benchmarks Xperia SP has the same fps (frames per second) as HTC One M8, Xperia Z2, etc. ±10%
So, yes.
I myself am playing Asphalt 8, Dungeon Hunter 4, Dead Trigger 2 on highest setting with smooth gameplay and zero lag.
When it comes to "Stock vs custom ROM/kernel" performance, I'd say that there is significant no difference. Custom kernels give you a little bit CPU boost, but that doesn't really affects games, while custom ROMs's performance isn't as good as the stock one, since Sony didn't provide us with the source and we have to use hacks, in order to be able to run 4.4+.

The problem is on your end. I was with stock ROM for over a month before switching to Custom ROM and I had no issues what so ever. Please don't spread false information.

Yes, you can play most high end games but stock rom ram managment are sh*t. After 24h~ usage free ram left 220-150mb most~. I tried "play" with ram manager but It didn't help.

Just because you don't know how to operate with your phone, that doesn't mean that the phone/ROM is bad. Even with stock ROM I had 250~300MB of free RAM with SwiftKey, NovaLauncher, WidgetLocker, Viber, WhatsApp, few xposed modules, etc.
As I said, the problem is/was on your end...

Can you make few SS for me after 24h[ofcourse no reboots]?. If you have more than 10-15 apps installed like me you won't get that amount of ram left after 24h~. No way.
as if certain user experiences would be a lie.
So does it worth the buy or any recommendations?

With stock rom you won't be able to play high end games without reboots for free ram. If you have time for flashing custom roms everything fine! But if you want to stay with stock I suggest you to buy LG L90 for example.
I wouldnt buy this phone in your place (I wish I hadn't bought it for myself too)

In it's price range it's the best phone specs wise.
Moto G is a worth buy as well, but it has Adreno 305 which is about twice as slow as our Adreno 320. If you like gaming Xperia SP is the best buy, however it reached it's EOL so you must rely on custom ROMs for further software updates. While Moto G will receive Android L for sure, and I'm pretty sure Motorola will keep maintaining it at less till the end of 2015 since the new Moto G 2014 is pretty similar to the Moto G 2013. But still Moto G's LTE model with SD Card cost more, so you must put this in consideration as well. Going with either phone, you will be pretty pleased. But if I had to buy a new phone now and I had ~150€ to spend I will definitely go with Xperia SP.
P.S.: I have both phones.
Thanks , for your information.
I'm sure to consider the Xperia SP.

this is phone is supposedly great but, as other user mention, the RAM is lacking so it makes it lagging. Sure some games run fine. but try playing real racing 3 with no modifications. it'll burn your battery (doesn't literally burn it, i just mean really hot) and it often lags.
camera wise, it depends on preference. for me this camera sometimes get awesome results outdoor, but it has same problem with many xperia phone. lots of noise if u zoom.
if u have time, read my 1 year review http://forum.xda-developers.com/showthread.php?t=2778795
The SP's gaming performance is pretty decent - and great for the price. If you're looking to get some idea of what 2D and 3D GPU performance is when choosing a new phone, searching for Antutu benchmarks isn't a bad place to start.
As for the camera, passable outdoors (but noisy), worthless indoors. Mine has even started taking out of focus pictures, even after half pressing camera button to focus first. Might be something to do with the len's protective film being removed (due to scratches)
The issue i have now is that it easily heats up when playing 3d games. Think before buying if you're a gamer.

Well I found out all devices I've ever used, my friends, my father's are all prone to heat up when playing high end games. This should not be the problem. As far as my inspection on my XSP, it won't get over the 41 degree Celsius barrier. However, I don't know about others though.
Now for some small hardware lecture. Ahem.
3D Games require more power
More power means the processor will step up its clock rate
Higher clock rate means higher power
Processors emits heat upon high power usage
Thus the heat you get.
Ambient temperature can make it worse too, so don't ever do gaming in a hot environment

Mine too doesnt go pass the 40 degrees mark however other Sony models specially the newer ones feel less hotter than SP so something about this phone is not right.

Well what you feel is different from what it really is. I believe checking the CPU temp on the newer Sony devices (x degree), and compare with our devices (40-41 degree) will finally unfold the mystery behind XSP heating, perhaps?
And difference between dual core and quad core do play an important role, you know

That makes it seem ironic, does 4 cores draw more power compared with our dual core? I believe so, since newer Sony models have more or less 2.0 ghz clock speed. I still can't believe those devices felt less hotter given the power that they carry. Anyways, this is just my observation that I hope will benefit the soon to be owners of this device.

Better ROM or kernel configuration for games?

Hi, I have a one plus 3t and I would like if someone knows a configuration to play, if it exists or something.
Thank you
As long as the Kernel does not underclock your CPU/GPU for Battery Life, any Kernel/ROM should be fine.

That's what I would think. The hardware on this phone is killer. Only bettered by Snapdragon 835 phones (or the upcoming phones for this year).
I wonder if the top poster is having a specific issue with games? Or just looking to tweak/overclock, despite no real issues?

I'm guessing the latter. He's probably on Stock, and he just wants to know if there's any possibility on increasing Performance in Workloads/Games. Nothing much else.
If he does want some recommendations, Caesium Kernel or ElementalX paired with Stock or a highly AOSP based ROM like NOS should do well. Not that the other Kernels or ROMs will be much different, this is just my experience.

right now I am using the z-unleasht, it runs well the games but it was out of curiosity if there was some configuration of Kernel so that it does not drink so much battery and render better
You should try helix engine: https://forum.xda-developers.com/oneplus-5/themes/app-helix-engine-v1-0-beta-3-t3745746/
Then use "AKT balanced" (change in settings). You can choose for every App other profiles -> change it to performance for your games.
Then you have a fast smartphone with great battery life, and performance while gaming.
You need to be rooted

It's not possible to go after battery economy while wanting to perform heavy duty tasks.
It's either one or the other.
Unleashed by my rooted OP3T on 8.0
thanks for the app i am researching to have ..
Hi guys, i have tried many custom kernel such as ElementalX, Flash kernel, Boeffla, Blu_spark, Wolfram..... etc and I still find that my OnePlus 3T can't handle big games..... unstable FPS even at low settings.... and It heats up pretty quick and render the CPU to lower its frequency, etc.....

Xiaomi must optimize the 660 chip.

i bought this phone last week, i am not satisfied with this phone, it gets hot when browsing, lag when playing games(because of the unstable high speed clock), i checked using the aida64 app and the big cores clock speed easily reach 2.2 ghz speed. that was unnecessary, even after turning the battery saver mode, the cores still easily touch 2.2 ghz. i already discussed this on the indonesian mi community, but then i got bullied, people saying it was my fault, not the phone. but there was many thread that complains about lag when playing games and bad battery life. i supose that was because the bad management of cpu cores.
note : i bought this phone in indonesia, with TAM (official) warranty
my rom is currently on the 10.3.6.0(PFGMIXM)
3+32GB model.

It's very commom for any Snapdragon device to reach top clock speed when in use, download CPU-z and do a little scrolling to see that.
The lag in games you're getting is most probably because of the 3GB RAM of your variant not the CPU as SD660 can handle most mobile games with ease.
About battery life, how much SOT are you getting? RN7 should handle at least 6hrs with some heavy gaming included.
And about temperature, how much degrees is your device peaking at? Anything below 38ºC should be fine.
And lastly, about mi community......well, most people there look like VERY inexperienced users, i wouldn't take them as a parameter to prove your point.

3gb of ram is good enough for gaming unless ur playing a heavy game while on youtube and facebook at the same time. the problem with this phone is the aggressive thermal throttling, once the phone reaches 40°c the phone becomes noticeably slower.
my advice to OP is unlock ur bootloader flash some custom rom, custom kernel and root ur device until you find the performance/battery ur looking for.

3GB of RAM has not been fine for some time now, there is a lot of games you wouldn't be able to multitask with any other application with only 3GB.
Few examples: TES Blades, Fortnite, PS2 emulation.
Also what are you doing to reach 40° on your device? As for mine never passed 38° and I live in a hot country(Brazil).
I Agree with installing a custom Kernel to improve your performance overall, but right know the best optimized ROM is still MIUI as many threads here suggest.

thats my point, 3gb is enough for games as long as you dont multi task. and this phone is mid range.
im in Philippines, room temperature here is about 37° heavy games like pubg makes my phone temperature skyrocket reaching up to 45° especially with thermal mod.
btw MIUI has the worst ram management for this phone. its closing background apps like no tomorrow, but on any custom rom its actually quite decent.

Yes the firmware is really not optimize, battery usage is really inconsistent (typical not optimize firmware)
All we can do is wait for the new OTA.
Strangely the PRO variant get more updated frequently (check official mi website)
But for us indonesian, we are stuck with NON PRO version if we want to use Official waranty hardware.

Thanks for all your reply, i apreciated it. probably i will wait until miui 11 released, and if the phone still gets hot i will install custom rom and use EX kernel manager to disable input boost and limit the cpu.
for bullying in the mi community, i guess its just troll account ? or the xiaomi guy ? every thread about battery gets bullied by those person only.

ever try miui.eu or masik?
these are very stable, miui-based custom ROMs with zero bloatware and better RAM management.
still a better ROM for people who want better performance / battery life on their xiaomi devices, but too afraid to live on the edge with AOSP ROMs.
AFAIK, that's called thermal-throttle/ing. When RN7 reach its peak performance and certain heat, to prevent overheat normally our device will slowing down its performance and it caused lags and fps drop for sure
I also encounter this problem when playing pubg even with smooth-ultra setting

It happened to me, custom roms aren't good for gaming then switched back to MIUI, when I play phone gets 45 C max, my battery gives 6 hours of straight online gaming, I'm on MIUI Global 10.3.5, Evira kernel 3.8.
:good:
660 wasn't designed for battery efficiency. Still waiting for Franco Kernel, it might fix the issue. My Redmi Note 4x can last up to 10hrs SOT while my Redmi Note 7 can only reach 5hrs even with custom ROM+greenify installed.

Nope. With moderate use I barely get 7, mostly 6. I got this sot by using apps like line, wa, instagram, youtube, browsing, downloading tons of file and one match playing pubg and pes.
I reach 8 to 9 hours sot only if i using wifi and playing videos constantly, minimum social media and no gaming.
Ofc people used their phone different each others. But, im sure they are having same battery drain. People talk about this so many times and everywhere. Ur case having 10+ sot like only happen 1:10 of all lavender users.

Its true continuous gaming on this phone (with stock miui) is bad. You will get smooth gameplay only in short term, like a one match pubg. Then it will start to lag because of heat. We need to keep the phone temp as cool as possible when used for gaming to get less frame drop. Example, playing close to a fan or inside a room with air conditioner on.

Yes, thermal throttle where the main reason. Its limit cpu whenever temp -read by system- reach 43/44 degree. A temp read by system are mostly not indicate the real temp. Besides, we have clockspeed max at 2.2Ghz, making our phone faster to heats up easilly. Thats why thermal throttling the cpu in such early time. (Its ruins gameplay, isnt it? :v)
If we look inside thermal-engine.conf on lavender, it use two sensor for detection and two step for throttling the cpu. First step it will limit clockspeed by 1,5Ghz and 1,9Ghz. Second step it will limit clockspeed by 1,1Ghz and 1,4Ghz. Because the temp gap between these step are only 1°, so mostly thermal-engine will going to limit clockspeed by 1,1Ghz and 1,4Ghz. Imagine play pubg with that clockspeed, lags and frame drop will occurs oftenly.
I've seen Mi 8 Lite with the same chipset playing pubg continously without any frame drop. I took its thermal-engine configuration and compare them with lavender.
Interestingly there are specified profiles for gaming and pubg are missing on lavender. Thus, both thermal-engine are really different. A same chipset should having same thermal at least. But, this show us that lavender thermal thingy are not being optimized yet while mi8 lite does already.

[EXPERIMENTAL] Throttling and it's caveats

While being owner of my Redmi Note 7, which definitely has some issues, I started experimenting with it.
Throttling is a common term amongst electronics and such. It's a way to safe our precious silicon from eventually cooking under high temperatures. There're a lot of issues involved here. Let me explain:
Xiaomi's belief is maximizing battery life while forgetting about optimal device's performance. Here's the issue, though - neither of which are properly calibrated. For a battery of this size, you would expect something better, but it's not. Looking through system files, there are several thermal config files, which simply tells to the thermal-engine binary at what state device should throttle. Sounds like a good idea, right? Yeah, not quite.
Upon opening these exact config files you see several lines, which describe temperature thresholds and which frequency device should start to use under it's determined state. There's more to this - GPU gets less voltage when it's getting warmer, thus reducing the ability for GPU to reach higher power levels. Everything would be great, if the device wouldn't start to throttle it's clocks at 45° degrees, which is basically nothing.
After seeing device's guts it's safe to state, that our phone has proper cooling done to it. Sure, it's basic, but with that much space and the price this phone is built for, you couldn't ask for better cooling.
So, what can you do to it?
There're several solutions.
-Deleting thermal-engine entirely and forgetting about the problem. Here's the thing, though - it's really dangerous, because not only you lose the ability to monitor your battery's temperature, you could cook your phone while charging. Charging throttling is a thing too, when phone slows down pulling current from a wall as soon as you are doing something intensive. It's a dirty fix with a lot of risks involved.
-Modifying thermal config tables. This way you could ensure device's safety while having optimal device's performance.
-Mounting hugeass cooler at the back of your phone or better yet - mounting cooler straight to the cpu silicon. Jokes aside, this is not recommended at all, unless you're insane and don't care about sacrificing device's size.
I'm actually thinking about making completely custom thermal tables and make them compatible with Magisk. Even if Magisk method wouldn't ensure enough confidence, I will make flashable zip for recovery flashers. Everyone's happy.
FAQ
-But the device has kernel level throttling monitor. That one works too, right?
-Yes, but it does not do anything related to cpu clock management and such. All it does is turning off your device entirely when undesirable temperatures are reached. Thermal-engine is what's monitoring temperatures and adjusting clocks when necessary. Kernel level throttling is there for additional safety, in case thermal-engine is not working properly.
-My device runs great. Why bother modifying what Xiaomi did?
-It's up to you to do anything with your purchase. If you are happy, it's fine, leave it as it is.
-I noticed hugely increased benchmark scores and games working smoother after deleting thermal-engine. Is that normal?
-Exactly. Here's your answer to what thermal-engine actually does. It hampers our device too much.
-When are you going to research this modification?
-As soon as I'm free from doing routinal things: school, job, home and such.

theres currently 2 thermalmod magisk module for our device, one is jthermal and the other is thermalx, currently using thermalx and it essentially removes thermal throttling, highest temp i got was 48°c playing pubg at smooth+extreme settings at noon.

I do not recommend using these mods! They completely remove the limits, leaving the phone vulnerable to overheating during charging.
but here is the link JThermal, I took the file I downloaded from telegram and uploaded it. To install use MAGISK!

Yes, I know. Everything in life is a trade. I'm willing to lose some battery lifespan for performance. Not being able to play games @60fps is unacceptable.

Most of the custom roms reuse already available binaries and stuff from MIUI, unless dev is clever enough to transition fully to CAF, so it should work, I think.
From what I've seen, MIUI is not any different when it comes to thermal configurations. Both of them use the same binary and same configs (they might be changed, not sure)

Can you tell me how to delete thermal engine please iam currently using redmi note 7 pro.Iam getting a lot of throttling please help

Question Any idea if 12.0 rom has better thermals than the 12.5 roms?

Has anyone compared if the 12.0 releases have better thermal performance as compared to the 12.5 release?
My K20Pro running on 12.0 is much cooler than my 11Ultra running 12.5. Sure, people have been saying that the snapdragon 888 runs hot but at the same time I've been seeing reports that other devices include the Redmi Note series are also experiencing heat issues after updating to 12.5.
Honestly for me heating has never been an issue, what do you think a good thermal would be like for you?
Probably like not reaching 39C for anything non-gaming or video calling activity?
Mine is not reaching it
Good for you. Many others are unfortunate like me
What is your room temp?

I felt the same way. I used it for 2 days with 12.0.9 when i got the mi11ultra and i didnt feel the heat. When i updated to 12.5 e felt it.
wondering if its possible to downgrade without bootloader unlocked?

Room temp doesn't matter, not when it comes to the 11Ultra. With AC on at a comfy 24C as opposed to just a fan with a room temp of 29C its still the same heating issues just a matter of the ramp up time for heat.

Damn, so its much better on 12.0.9? I'm going to flash 12.0.9 this weekend. AFAIK, downgrading either way will require a wipe and I think you'll need to unlock BL either way.
May be not what you are looking for, I rooted the phone for CustoMIUIzer tweak. I also installed Franco kernal and there I underclocked the kernal CPU by 25% (75% working) and optimized its GPU. This has dramatically improved the thermals and battery performance. Idle temp of the phone drops to 25C regularly. For the past one day, it has not reached 37C when doing routine browsing, calling and texting etc. The temp jumped to 40C during HD video playback, and once to 41C while playing angry birds. During quick charging at high ambient temp, it touched 44C once. Normally with the Mi quick wireless charger (80W), the temp variates between 40-43C.
Im yet to notice the anticipated drop in performance of the phone. For routine games and HD video playback, 75% performance of this beast is enough so far. It is as smooth as it is supposed to be.

According to my daily use of the phone, I do not need the full processor power. Seventy-five percent power is enough for that. For some long tasks, such as reading a lengthy pdf or google maps on a road trip, even 50% CPU power may be enough, granting enhanced battery performance and heat management. For the most intensive tasks, I can restore it to its original might (or even overclock it for that matter) just by toggling a switch, if that shall be desired. Options are good to have. A software fix and aggressive management of heat officially by Xiaomi, the point here by OP, will be welcomed of course.

actually a snap865 is really really fast and more then capable of running everything except gamming in comparison, and if you don't game high 3d games then you don't need the full power of the snap888 which is 25% faster.
I actually paid 850€ for mostly the camera and the media comfort, so i have to agree with hellodrsoul, if your main goal is have a phone for this purposed(no hardcore gaming) then capping it is a good thing,
also yeah Xiaomi is lacking in the optimization department.
on March everyone was stating in news about the mi 11 ultra
World’s First Full Phase Change Heat Dissipation Technology​either it sucks or xiaomi software team is at blame.

You are right. There are no custom kernals available yet. But the FKM has the option to underclock the CPU and GPU and for me it works flawlessly.
