How does everyone feel? I've always assumed that it forces better battery life but I've noticed a lot of people do. I've done it till now just because I figured it has to help since every kernel I've used on any phone is under volted. Do you think it helps? Any kind of proof is welcome but so are opinions.

I'm on board with a modest under volt, but when you drop the voltages to the point that the phone is no longer 100% stable any minuscule battery savings would be undone by the forced reboot.
GN's cpu uses a power management technology called smartreflex which dynamically changes voltages used by different frequencies. The values that are set with setcpu and similiar apps are only the maximum voltages that smartreflex is allowed to use. The actual voltages may be well below the nominal ones.
Personally I never noticed any significant improvements. It's hard to tell how much but it is definitely not worth going really low. Right now I am using leankernel which is undervolted slightly by default.

This.
Apps may stop working randomly or the phone may have random reboots if you mess with the wrong speed.
Honestly speaking, just go to setting...
1. then data and limit background data of certain unimportant apps
2. developer options > background process limit. Set it to like at most 3.
These ways are much safer and will boost your battery life.
Thanks. Right now I have a decently aggressive but stable UV but I'm gonna up them another 50mv just to be safe and do that. Thanks for the suggestion I didn't know I could do that. I'd hit thanks if I wasn't on a phone...

Can someone please tell me what is considered "normal"?
Mine runs at about 55 constantly, is this dangerous?
Hi,
http://forum.xda-developers.com/showthread.php?t=1557494&highlight=cpu+temp
For example,there is another threads...
55°C is not dangerous and I doubt it runs constantly at 55°C,in sleep?when your browse on the net?when you watch a movie?or just when you naviguate in settings?
So,normal if you have this CPU temp while browsing or whatching a video,not very normal if your just naviguate in settings since 10 mins... (according to the CPU freq?) or if your phone is in sleep since 10 mins (if you do not download anything)->wake up and you see 55°C...
While it is charging?
The CPU temp limit is at 64°C (if you don't modify it),above thermal throttling,reboot...
And it's with stock kernel?custom kernel (CPU freq?voltage?),what are you doing exactly with your phone?

Thanks for the response mate.
I flashed Franco M3 last night and was admittidly browsing a lot before I went to bed and this morning.
Looking at it now where its been sat on my desk at work for a while its hovering around 35.
I suppose I was just looking for a little assurance my phone isnt going to break into a ball of flames suddenly!!!
Again appreciate the response mate, Thanks

In sleep,for example since 10 mins?without touching it?
Mine in sleep is at 22°C in my home (current ambient temperature about...24°C).
In extreme use (for example during a bench ) go to about 86°C...
In browsing about 55-56°C.
In light use (setting my home screen for example) about 40°C.
For example with System Tuner pro you can follow in real time your CPU temp (with graph).
Running at 1.42Ghz actually.
And in normal use I settled my CPU temp limit to 75°C (stock is 64°C),I feel that by increasing the CPU temp limit the phone heats a little less.

Always wonder on these forums and dont take this the wrong way but is their any other point than upping your benchmark by overclocking.
Do you have any noticeable difference in performance thats worth the loss in battery.
Thanks again

I'm just curious because what you said confuses me lol but, how exactly would INCREASING temp limit make the phone get hot less?
I don't know much about how that works (the nitty gritty details) but that seems kinda Counterintuitive?

Hi,
I do not know any more ,like I said "I feel"...
At the same CPU freq and about the same use I feel with a higher CPU temp limit the CPU heats less...that's what I thought noticed when I monitor the temperature evolution in System Tuner...Why?,Placebo?Not exactly the same condition?I do not look exactly at the same times (after a high load) compared to the stock CPU temp limit?...I don't know much...
I tried to reproduce the same conditions for both CPU temp limit,and I think I noticied this...But it's not "scientific" nor proven...
I may be an explanation in French but I can not do the same in English even with Google Translation...,too hard for me
And I am not a engineer in processor and I do not have large knowledge in this...And maybe,certainly,my explanation is crap

Re,
Yes there is a performance improvement it depends in what...
Some apps loads faster,my launcher is smoother (Apex),scrolling is better,etc...
Some people do not notice the other yes...
Even withe the "better" kernel,the more you overclock the more your battery life decreases,but it also depends of the voltage,governor and what you do with your phone...
If I run 15 benchs at 1.65Ghz for stability test (or for to show that I have a big **** LOL )...Bye bye the battery...

Lol thanks
I was just wondering if it was something that was proven
Thanks for explanation.
I'll have to check for myself sometime I guess
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
@bradipovsky, that's the same guide I will follow

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

I don't use the highest freq's, cause it's not needed for me. I limit the highest CPU freq to 1GHz.

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.

Well, i don't really understand WHY it doesn't save more than 2% of the battery life. Afaik, EXUV does reduce heat and improve battery life by miles. But that's what I thought. In reality which is this, im not rly sure why that even with EXUV, it still cant save more than 2% of the battery life.

I'm not technically expert with things like this but I have read an article/ blog before that undervolting may damage a phone since it was designed to work with that specific voltage. So, I actually didn't do that even UC or OC. Just saying.....
Undervolting doesn't save battery as your CPU will still try and draw the manufacturer set levels.
If it doesn't get those levels it must step down its own level which essentially means that the activity that needs processing needs more time, and consequently, more battery.
Even if you manually adjust the clock speed of your CPU down to match your new voltages, the same applies.
UC/UV is quite simply the worst voodoo that persists across these forums.

we can control the hardware through software so we can control the voltages and frequencies through kernel
devs can put new frequency levels as manufacturers did (like this :https://github.com/Christopher83/samsung-kernel-msm7x30/commit/899d5a296a43a6d32c2468bba8121c3a1915dd68)
if its not true and if this method doesnt work, Why all kernel devs on XDA trying the same thing??

https://github.com/franciscofranco/hammerhead/commit/104890313a73dae0e7d7a13975801cc568d231ad
in summary EXUV and UV are absolutly battery-friendly
and do not forget undervoltage cant damage the hardware but overvoltage(ı mean OC) can damage the hardware

I've based my reply above on this post.
It is a much longer version of what I summarised earlier.
And, sorry, even UC/UV can damage your hardware in rare situations.
It does baffle me why people spend so much time tweaking things as you mention when the net returns are negligible, and often cancelled out.
So to sum all this up. We just have to leave the CPU & voltage tables alone since it damages hardware?

It's not that you have to, but that chip designer recommends it.

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)...
Forgot screenshot....

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...
