You should try them and find out the most suitable for you, use them for 1-2 days, you'll see the difference.... personally, I'm using NoName kernel with RR
NoName for Lineage based.

God knows, but what I do know is that it should produce less heat at the very least and it performs pretty gud on powersave governor. The gpu on the other hand is garbage at min freq (160mhz), even the launcher lags....

Mine was fine but now I'm on Aosip.
i think for now the best is to use a stock kernel, be careful with the charging limits.

Of course it operates at lower voltage as it's a lower frequency and requires less power draw. Lower voltages should mean lower heat, however you don't magically get that lower freqs to operate, you need to tweak the interactive governor to make use of them all efficiently. So far I'm on Kirks kernel and AOSiP and it's a quite good combo.
The lag is not caused by low GPU freqs, it's because of low CPU freqs for that particular load, so governor tweaking is needed.

Lol, I tested what you said out. Because you said it with such confidence...
I changed the cpu governor to performance and set the gpu to 160mhz max...
That made the experience a bit better but it would still lag a lot in recents and app launcher scrolling...
I've attached a screen shot to prove it too...
Another thing, just because the clock is lower does not mean that the voltage is lower as well, many devices that ive owned over the years have had the same voltage's for lower clocks( moto g2, Sony xperia z1)
And lastly, you should "magically" get those lower frequencies(if they are truly unlocked) since governors will always operate within the min/max frequencies that are set by the user or by default(unless it reverts parameters back to stock, like our device does on interactive)...

First of all, we are talking here about difference in voltage between stock minimum freq for big cluster, which is 1.1ghz and actual possible minimum which is 300mhz, and there is a difference in voltage, that was the point. The devices I owned, S5 and Z3compact had more CPU steps, therefore the difference between some of the steps was really small or there wasn't any, but the CPU scaling made a jump to the freq with bigger difference (higher or lower, that was the stock behavior so some freqs weren't used). Here it might use all of the freq steps as there are less of them and the difference in voltage is significant enough, which might be the case, I said that because of my experience with previous devices. But you've missed the point anyway, I have said that even if unlocked, some freqs won't be used just because they are there if the governor parameters aren't set properly (or will be barely used). That was my point, I said that as a general note, so users won't jump the gun and blame devs for whatever.
And another one, regarding your test and lag with GPU, now I'm confused why would you set your max at 160mhz? I know it was for testing purposes in this case, but you did complain about it in original post and I said it won't lag because the max would still be set to 430mhz in which case the GPU freq scaling would do the job which it does very good so far. It would lag of course if you set max GPU freq to 160, but that's not what would you do for daily usage, right? Sorry if I misunderstood something.

I kinda get what you mean, but the min freqs should kick in by default. They don't though on kirks, you need to change the governor to something like alucard or zzmove once before it actually starts clocking down to 300mhz...
On a side I would just disable the big. Cluster if I could, I don't really need that much cpu performance...
I was trying to find the min gpu freq that would be usable and I was disappointed, cuz my Sony z1 had a smooth ui experience with the gpu clocked at 200mhz max and that thing had a sd800...
Btw, I do all this to get better battery life...
I found out something else, I can't use power save governor any more because it can't handle audio processing(ainur, v4a) when the screen is off...
Just like my old z1, Lol...
Makes me think that the performance is really identical to the snapdragon 800...
I wonder how pissed I would be if a I got the redmi 5 plus, the 625 would have been even worse...

Yeah I agree, it should, but how much it stays on minimum freq is dependent on couple of governor parameters (talking about interactive). On mine though it does stay on 300mhz when idling, on stock Kirks settings. Big cluster can be disabled through new hotplug solution, like Intelliplug, which I used on my old devices, and it performed great, 1 core was active when screen was off, screen on and light usage required only 2 cores, while all 4 were active under heavy load. Here however there is only Qualcomm's hotplug solution, until that changes, no luck. Regarding GPU freq, I don't think any device would work smoothly under 200mhz, you can set 266mhz here, it will be smooth, I've tested today, on my old SD801 it performed at 233mhz IIRC.
I've seen that, V4A requires higher freq than 300mhz, or even 422mhz which SD801 had, it's more about the freq rather than the chipset, as I've read on multiple threads that even the devices with SD820 were struggling a lot when processing audio at 300mhz when the screen was off. Don't worry, it's a general issue. There is also the optimization of the rom and audio mods as well, background tasks, kernel, it all goes into the mix.
This is actually a very good chipset, it's technically SD660 just with lower clocks on both CPU and GPU.
EDIT: I forgot, this is my usage on AOSiP + Kirks, stock interactive tunables, min freq 300mhz (big/little), GPU initial/min freq 160mhz, max 430mhz. Using microG instead off GApps, I have used FB, Instagram, Messenger app for 1,5h each, Viber was couple of hours, Chrome some 30mins, Panini sticker album 30+ minutes, 30 minutes of 2G calls. Network mode was LTE, though I was on wifi on whole charge.
Started measuring from 92%.
Thanks bro, that explains a lot...

The galaxy has a big jump from 400Mhz to 800Mhz. Is it possible by modifying the kernel to an intermediate step (600Mhz) or is the hardware limitation?

I think you should read the title... I mean the governor of the cpu. It has various speeds to save energy...
Yes. I beleive SetCPU can do this. I haven't tested though.
I think its possible, I've just added one scaling from 100,200,400,800,1000,1200
SetCPU can do that

Only with a stock kernel? So why I can only choose 100-200-400-800-1000 speeds? The ideal would be that it can be set to 600MHz, plenty of power for everyday use
You would have to change the cpu multiplier in order to get a frequency in that range.
You can't change it without adding 600 MHz in the source. SetCPU can only choose the speeds given to it by the source code. I wouldn't be too worried about it though. It only speeds up for as long as it needs to complete a task then it's usually back down to 100 MHz.

That is the question. The more intensive use it is when I use the web browser. And would have the necessary fluidity 600Mhz spending less to have it running a while to 800Mhz.
Anyway I see that the overclock is the same as a PC, with the difference of having to modify the kernel. Time will tell if any of those that modify the kernel have the same need and put it.
PD. Google Translate rules...I'm spaniard...

Hello !
A good CPU governor is design to get most CPU performance and save energy without altering too much reactivity (=introducing latency)
This is why the governor jump "as quick as possible" to high frequencies.
BTW, the quickest the CPU calculates the operation asked, the sooner it can go back to deep sleeping states.
Setting a maximum cpu frequency other than 1GHz (800MHz, 600...) is counter productive.
You'll loose both speed and autonomy because the CPU won't be so often in deepest power saving states.
(you'll find many studies about this )
Hi, just wanted to know what is original HTC's ROM CPU scaling range and what is its CPU governor. My guess is 245-528, ondemand - is that correct?
Sorry, I don't know myself, but I'd like to know this too! I've just installed JokerDroid on mine, and I want to set it to stock frequencies so I can improve the battery life.
I'm using 352-691 ondemand, but I think 748 is ok too.
I think the min is 352MHz. But again, I am not so sure. (I arrived at this value when I was on the Stock ROM and used Android System Info which shows the various CPU frequencies and the time periods they operate on that frequency)

Custom ROM's (Or, more appropriately - Custom Kernels) allow you to set a CPU Speed upto 768MHz.
BUT - The performance increase is not as great as the speed increase shows. So, if you do overclock, don't keep huge expectations.

I am running on 710 max, some people run on 768 max. But apparantly it is phone related because some people can perfectly run on 768 whilst I read a few days ago from a person here whose wildfire started force closing things around 710 or one higher or so.
Try a bit yourself which works for you. There are benchmarks that you can let run to see how often an error will occur approximately I have no link myself but I know a bud of mine did that to try how high he could go
At 691, some apps force closed, so I'm back to 595. It was stable for me.
gues that the 352MHz is the stock minimum then. There should be a noticable battery life increase when 122MHz is my current IDLE clock huh?
Now Iam running 122-710MHz on stock HTC ROM, very stable. If I set the frequency above 710MHz the scaling become unstable uner LOAD sometimes and dropping to 480MHz.
Using jacob kernel v4.
So, I know we all have different phones, and after looking at a review of some voltages to try, I changed all the stock voltages to the ones I saw and saved them as default (don't ask me why, I do not know myself). Since this, I set my phone to hotplug and the phone has had multiple Sleep of Death cases. I think it has to do with the voltage but it could just be my phone not liking hotplug because it stops if I turn off hotplug. Or hell it could be that both together are causing it. So I was wondering could someone provide me with stock voltages at 384, 729, 1036, 1228 and 1344 mhz. Or better yet if you could provide me with the best voltages that help save a little battery life. Thank You! (Also I have been looking but have not found the stock voltage for the numbers I listed above)
stock voltages are 1025, 1203, 1317, 1380. 1350mhz is not a stock clock speed so theres no stock voltages. you can try these undervolt values, they are pretty conservative 850, 950, 1050, 1175 and 1250. remember to do nandroid backup first.
undervolt will not really gain you any noticeable difference in battery life, the cpu uses relatively little power to begin with so reducing it by a few hundred mv is not going to make a different with normal use. If you want to try it out just start from stock and go down 25-50mv at a time and test it with some games or stress test.

Thank you. If they really don't make a difference I will leave them be at stock. Any good value for 1350? Or should I just stick with 1250mV? Just really trying to get 2 days out of the phone, but I assume I cannot complain since I am already getting 4h of screen time with normal use on the 2000mah battery. I will look around here some more and see if I can find any more useful tips on better battery life. Thanks again!

Ya thankfully read it, tried these voltages with hotplug on and screen off settings and the phone did not sleep of death this time, but it froze right after wakeup, so no hotplug for me, just conservative.
Also, be very careful with CORE and IVA undervolting. In my case, undervolting theese too much caused the exactly same issue you are dealing with. Same goes with profiles for SetCPU profiles which also causes the phone to behave like that in some cases

So for what I can make out from your post, some reason its setcpu profiles not working, not the phones cpu itself not allowing it be put into hotplug mode? also, sorry for the noob question but what is the difference between CORE and IVA undervolting? Or should I say could you explain them to me.
If you are going to use profiles, your phone should be very stable. In other words undervolting makes it instable if you tweak it too much. Core and iva are very sensitive. Core is your graphic gpu. Let them stay at the normal settings. Use milestone franco stable build undervolting only the cpu. Rather 700 mhz at the lowest. Try it out

Has anyone tried to undervolt his Note 8?
I'll be undervolting my N5110 soon...
So, am I the first one to it or what?
Please share your sets.
Here's my settings. I run CivZ ROM with built-in kernel
I messed with the same rom... yes I undervolted and overclocked and done as much as I could do. Went back to 4.2.2 stock and still get about the same performance, and battery life. One thing that I could not live without, is my 64gb SD card. Too many issues with FAT32 and my music and video files. EXFAT is the only way to go with 64gb SD cards. With my stock ROM, I get 8 to 10 percent every hour, and 15 percent every hour playing HD video through miracast to my TV.
I'm doing it right now, following this guide (not as closely as I should, most likely).
@Alastor_ru : how did you get your values? Mine are generally lower, besides the fact that Voltage Control allows 850 mV as a minimum.
Thanks, but what about the higher freq's voltages
I think that you have up to 1.9 GHZ or 1.8 at least

I use SetCPU, it has 600mV as a minimum.
I perform several steps while set voltage to lower and lower values and stop to play with it, when I get my current settings. As I noticed, the biggest power eater is the screen, so undervaluing doesn't bring the big savings

Well, 8" of screen of course don't help the battery I'm doimg it mainly to limit the heating, so high frequencies are the most important. I think it's a better option than underclocking, but that's just my opinion.
I'll share my values later, but I don't think they're ideal yet.
As I'm the typical user that underclocks because I don?t use games or heavy apps I'm used to use some apps to do this, but, they are very outdated (setCPU, our dead friend) or they are incompatible... francokernel, trickster mod, kernel adiutor... you can lock freqs but the CPU doesn't give a duck about those apps...
Why? and... is there any way to underclock?
I can live with hotpluged cores limited to 1200mhz and a gpu to 4450mhz... I think we would improve the battery a lot but... we can't limit the cpu-gpu..

Kernel adiutor works perfectly fine...i have been using it with no issue since i got my g4 2 months ago...also i have found to save battery it's bettet to raise lower clock speeds to 633 and 460...at stock setting it wakes and throttles way more than it should...it stays more stable at these speeds and i get amazing standby time...also smoothes out a bit of lag...this has been my experience on all my g line devices

Speaking about CPU core frequencies, will SetCPU work? I have another question, I noticed when looking at the CPU with various programs, it's always 1.2Ghz, doesn't the G4 actually have a Hexa(6) core 1.8Ghz CPU, what happened to the other 600Mhz?
