Is this a common problem for everyone? (Small problem) - Xperia Z1 Q&A, Help & Troubleshooting

Before we start, I'm running The latest firmware .757 with Advanced Kernel.
So the problem is the minimum frequency is shown as 1190Mhz but it's running as low as 300Mhz. Tried changing it to show 300Mhz but it keeps changing back to 1190Mhz.
Any ideas? It's not a big problem but it's becoming very annoying.

You don't use all the time the maximum frequency of CPU cores...i've tested myself with the same Antutu CPU Benchmark and i have the same, in IDLE the cpus frequency is 300Mhz, if i start a game that jump to higher frequency, there is nothing stange here.

I'm talking about what these 2 app shows me. My minimum frequency is 300Mhz yet it's showing 1190Mhz.

That mean that the minimal frequency is 300Mhz i don't understand your problem i have the same thing, when the phone is IDLing it's at 300Mhz, that seems legit.

Yes my minimum frequency is 300MHz but both the screenshots is telling me that my minimum frequency is 1190Mhz, which is wrong. My problem is that they're not telling me the correct frequency.

The first one said your current frequency is 300Mhz (your phone IDLE) and minimum 1190, this app seems just broken or wrong.
The 2nd clearly show the minimum is 300Mhz and the current is 422,4Mhz
I trust Antutu CPU Master because i have the same results.

Try a different CPU app, like set cpu, see what that says, i think it could just be a glitch on that CPU app.
Chances are it's reporting it wrongly and it'll be down to the app, if it was on 1190 all the time your battery life would really suffer for it.
Also try to alter the governor in the app, could be that on another one like interactive or power save it'll yield different results.

This is because of Qualcomm MP-Decision that controls the hotplugging, that tells the CPU to boost MIN freq to 1190 Mhz to fake UI smoothness and response, about 2-3 second then ramp quickly down to 300 Mhz, and then do the same over and over again. Good for performance, bad for battery.
This is also a part of Qualcomms own Project Butter solution - using / forcing the device into overdrive mode w/o any thoughts on heat generation / stuttering by nearly instant & uneven shifting between frequencies, thanks to a built-in touch boost feature that is boosting the phone to 1190 Mhz in Z1 case, was at 1026 Mhz frequency spectrum at Z / devices that used the same QC shipset as the Z.
This is fixed by @faux123 in his rewritten Intelliplug module, that conserves / keeps the performance (even improves it..) and boosting battery life with a more natural step pattern through your device various CPU clock frequencies.

I have the same problem. Can't even set my min frequency to any other then 300MHz.
Would like to raise it a bit becose sometimes its freezing when starting the camera using the physica button.
I can only change the max frequency.
Any help Would be very appreciated.
Thank you
Z1 4.4.4 stock & locked bootloader

I had the same problem, just try the No-frills cpu control it works for me (when your phone is idle it will always running at 300 because it is trying to save battery)

[Q] Profiles For SETCPU???

I'm using (all conservative for Galaxy S phones)
The "Main" tab profile is set to 1200 max/100 min
Temp > 49.8 C - Priority 100 - 800 max/100 min
Charging/Full - Priority 95 - 1200 max/100 min
Screen Off - Priority 90 - 400 max/100 min
Battery < 12% - Priority 85 - 600 max/100 min
Battery < 25% - Priority 80 - 800 max/100 min
Seems to be working well for me so far. Not sure if this is the "best" way to do it, but it makes sense to me.
I have found set cpu to be completely useless and not help with battery life at all,i just leave it on 1000/100 1200 seems overkill. Plus why would lowering it save battery, if it was low it seems like it would just take longer to do something sucking up just a much battery life than if it was set high and got the job done faster.

Unless you have Unhelpfuls over clock kernel with a custom profile (Interactive). With the stock kernel that's correct, using the "Ondemand" profile it will cause your phone to not wake up and you get the pleasure of taking your battery out to reboot it.

That's the thing tho. The phone (without having setcpu intervene) automatically clocks its self down to 100mhz when the screen goes off. So I wonder what setcpu does that it makes the phone pull a sleeping beauty

It's because "ondemand" profile, it doesn't play nice with the galaxy s phones when in sleep. If you set it to ondemand for the main profile and conservative for when the screens off you won't have any issues.

what is the best overclock frequency i should tune for x8??

i'm using ginger dx v28> and i flashed overclocking after the Rom So What Is the best frequency to assign as i'm using setcpu 3.1 >
For Stock Kernel .
Set it to as high as you can without the phone rebooting itself the best frequency varies between phones as far as I know

OCing will always affect your processor. It's what it does.
Your oc value, in my experience, is dependent on the user (eg: smoothness/performance vs battery life). Stick with what works for you (but always mind you temp - just to be safe). I can oc above 710 but i rarely go above that cause it's more than enough for my daily/normal use, though i raise it when playong games.
Yes min frequency can be changed. There are a lot of ppl who know mre abt this than me, but (again) personally i prefer to set it at minimum and simply change governors when needed (i set it to on demand when watching videos).
Hope that helps.

what is governors and how to change it . i see it in option but i don't change any th
I'm not an expert in overclocking area... but as far as I know a governor is like a whole configuration pack for the CPU behavior: how it must act when the phone is sleeping, how it must act when it "wakes up", how and when it must jump from max to min values... I think that governors can be changed using the performance menu if you are using a cm7 based rom, but they can always be changed from the main screen on setCPU. The group of governors you can use depends from the kernel you have, I think. You can about some governors here: http://forum.xda-developers.com/showthread.php?t=843406
For me the one who has better balance between battery length and cpu speed is smartass V2. Hope I have helped. Good luck!
Oc will affect the cpu life i guess and the battery consumption. Governor will manage the cpu and the battery usage. Eg.when the phone sleeps, wakes, etc. U can use smartass on stock kernel and smartass v02 on custom kernel. From what i read, smartass affect dsp manager.
Hope it helps.
Sung to you by a walkman.....
okai thanxs all i see governor icon in setcpu i wanna the rates of the option in governor to adjust it as i'm using stock kernel
powersave bias 0
ignore nice load 0
show differential 0
up threeshold 0
sampling rate 400000
or is there any other app for govenor only
plz reply me
Im not sure if i understand correctly.
In setcpu there are a couple if tabs. In yhe main tab is where we change freq and governors:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now if you want to edit your a governor further you go to the governors tab:
Now the thing is the governor tab changes depending on the governor you set in the main tab. For example, smartass will let you edit more values the, lets say, ondemand.
Now when you're in the governors tab simply tap on the option you want to change, change the value, then hit apply.
Hope that helps.

Absolutely it can decrease your x8's life due damages to chip set & overhead.(+high battery drain)
anyways overclocking more than 729 MHz is not recommended (by me)

Firstly you can't burn phone with overclocking.
Seconldy, stability of cpu depends on the level of batery. For example: My phone runs 806mhz without any problem when batery is fully charged. When baterry level is about 60% my phone is much more unstable. So try to set this frequency when your battery level is low.
Are you sure its x8?
Lol
What have you done to your phone??:what:
:good: as long as you don't have any problem its ok
Do a big smile, because you are lucky. And this is normal, the 7x27 chips can handle 8-900 MHz without any problem, but the most x8 owner have low quality SoC with 600 MHz, the high quality chips marked and sold as 7x27T with 800MHz default clock (you can find it in low end galaxy models and other phones what equipped with 7x27 but the default clock is 800 MHz).
Wait while the battery level is only 10-15% and burn the phone with games/benchmarks. If the phone not freeze while the battery turn to empty, you can use this frequency (when the battery level is low, the cpu got lower voltage, this is normal, the difference not significant, only few mV but sometime this is enough to make the phone unstable).

i used 864MHz when battery was at 7% and i did antutu benchmark score was about 3780...it's stable also with very low battery
anyway the score wasn't so good i guess because sdcard is really bad
i will post screenshot of battery and antutu as soon as i go again at low batter

I dont think theres any life drop on the cpu when overclocking too much - contrary to what people believe. Ive oced dozens of cpus and havent seen one burn and die from that. All modern chips will simply reset if they cant handle it.
My shakira can easily handle 800+ so its always running at these levels since i got it. And yea, its better at benchmarks like this

The ROM already had the module, but it wasn't provisioned for in hw_config because of possible instabilities. All I did was to insmod it via Terminal Emulator just to see if the overclock was possible, but the system crashed almost instantly. When the ROM was still fresh, it actually managed to work, but everything was extremely slow and laggy. My idea is either that the stock kernel or the ROM just don't do that well with overclocking, so I just abandoned the concept completely. Besides, I'm satisfied with the performance anyway. No need for perfectionism here

I think because it's not actually handling that frequency, for example for slow scrolling Max needed frequency is ~729 if you scroll faster kernel will need higher CPU performance & it'll use all 864 MHz then rebooting happens

He can be right. It can depend on the governor you use. If you use an Ondemand governor, the CPU scales the frequency between the min and max values. That is , if there is a high load then the CPU scales to higher frequencies and when in lower load then it automatically reduces to low frequencies. So when he switch his clock speed he maynot have much load but after switching when a load comes to the CPU it scales the frequency to the highest possible to 864Mhz. So it reaches an unstable condition and reboots.
So Jay-Z-S may be right.
Haha..
My phone stuck at 844 Mhz (when selecting the Maximum CPU frequency) LOL..

If you select powersave governor your cpu will stand on minimum so you can set max to 864 ,without reboots because CPU frequency won't rise to 8xx ,that's what I'm saying if you don't use all 8xx MHz you can set it as Max (but on ondemand all 8xx will be used & rebooting happens cause of a lack of cpu's silicon )
Like mine on powersave max864 min 245 on powersave governor (actually running with min frequency)

K20 Pro possible CPU core throttle?

Hello, I bought the phone yesterday (Indian global rom) and after an auto-update for MIUI 12 (12.0.2.0 QFKINXM), installed geekbench 5 and antutu (8.4.4) to try them out. I got substantially lower score in antutu (compared to reviews, YouTube videos) and breakdown showed it's the CPU causing the low score. Upon further benchmarking with Geekbench 5, geekbench 4 and 3dmark it was evident I was getting low score across all the benchmarks where CPU was involved and fantastic score in gpu-only tests (like multiple scenarios in gfxbench).
Then I installed Aida64 and "CPU Monitor" app to further investigate the issue and find possible correlation with temperature etc. The temperature seemed to hover around 55/65 deg while stress testing and 35/40 deg when idle.
I then checked the CPU clockspeed with CPU Monitor app in split screen mode while running Geekbench. I noticed the fastest Kryo gold 485 core (with 2.84 GHz speed never reached the peak). I then ran the Antutu 15-min stress test, and also "CPU Throttle Test" app and "CPU Load Generator" app while keeping the "CPU Monitor" app open in split-screen and noticed the same thing, the most powerful core never reached its peak and mostly runs at idle clock speed of ~800 MHz even when benchmarking. Further, even when that core boosts, it seems capped at 2.4 GHz which is thehe maximum clockspeed of other 3 Kryo gold 485 cores. I know 2.84 GHz isn't supposed to be a sustained speed but the fact that it never reached it and gets capped at the same speed as the other 3 cores implies something is wrong here.
Also I don't really know if the poor score is solely caused by the poor performance of that 2.84 GHz core but I do know from observation that the core isn't running as intended as I explained above.
Now if it's a software issue then i wouldn't worry much as it'll possibly get fixed in next updates or by installing custom rom. But I'm worried if the issue is related to hardware itself (problematic CPU core or heatsink issue).
So I'm writing to know if any of you guys have had such issue or what do u think it is caused from or possible fix. Also
Any constructive suggestion will be highly welcome.
Geekbench 5 CPU score: single core ~600, multi-core ~2200 to 2300
Antutu 8 CPU score: ~90k (sometimes much less)
I have an mi 9t pro with the global miui 12.0.1 and it's similar to what you're saying, so it's not a hardware issue, it's the kernel, it seems that Xiaomi it's very conservative about the battery and throttles the prime core to 2.4ghz max
The only thing that have worked for me was to change the kernel to another one, I'm trying Yuki kernel and it's very good, also there's a new kernel, quantic, and it's very good too, the battery doesn't seems to take a big hit, it's fine for me, like the original kernel, sorry if my english it's not perfect, I'm from Mexico

Hello, thanks for your reply and your English is awesome.
Now regarding the kernel change, all the reviewers and YouTubers benchmarked it in stock and most of them didn't face such problem. Their score seems reasonably similar to each other.
Also do u remember if your CPU benchmark score was substantially lower than standard before changing kernel?

60c is where CPU starts to throttle, prime core never runs at max freq for more than 3-4 mins regardless of temperature to save battery and wear from the heat it's producing on stock kernel.
Also never forget how much a impact ambient temps play a part in phone performance, I've put my phone in the freezer for 5-10 mins and saw a 500 multi core score although that was on a warm 40c Aus summer day lol
As others have suggested try custom rom if you really need max performance although it is completely unnecessary and a waste of time pursuing max performance, take it from someone who's been there.
The result after a month of trying every combination of roms and kernels lol

Thanks for your reply. However my issue is it never reached 2.84 GHz and is artificially capped at 2.4 ghz. I'm not talking about the core being constant at 2.84 GHz.
Also I'm not necessarily looking for absolute max performance as I'm not a gamer but just wanna investigate the issue to make sure it's not hardware issue.
Btw if you've come back to stock rom/kernel, can you pls test and mention the geekbench 5, antutu 8, 3dmark scores for K20 pro?
