im running the extreme1.92x kernel oc'd at 1.4 but not sure about the best setup to save battery. i made one profile for charging i put in on max. not sure what to do with the advanced tab settings.
Profiles are really dependent on the user and their needs. The one piece of advice I can give you is to make sure you have a profile set up in case your phone starts to over heat. An OC'ed phone maxed during a charge may get quite toasty.
any suggestions?
Imo dont o/c. Let the kernel operate the way it is setup. O/c cause reboots, phone heating up, and freezes.

I'm running Adrynalyne's 4.4.7 kernel and use the following and get really good battery life with no overheating and no lag. I don't do a screen of profile because the governor seems to handle that pretty well.
Normal 1024 max 245 min-Smartass governor
Profiles:
Battery < 25% 768 max 245 min-On demand Governor
Charging 1280 Max 245 min-Smartass governor

Does that actually work?
I thought you had to choose a default governor and setup profiles accordingly.
I didn't know you could setup profiles with a governor that wasn't active or chosen on boot.
the thunderbolt is so fast already theres really no need to over clock. i left it at stock for normal, toned down to 768 when <30% battery and down to 368 when screen off. its a little slow for about half a second when waking up but the battery life is amazing. i can make it through a whole day without charging with moderate use. also running ziggys bfs kernel on virusrom and that added a ton of speed. way better than overclocking that drains your battery
im not asking about overclocking or profiles, just want to know about advanced settings. everything is set to default -1.

What Rom are you using?
Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.024GHz max with ondemand governor and most importantly SIO Scheduler. Try these n you will have amazing performance and better battery life. Let me know you opinions

Haha, I couldn't tell if you were being serious or not but each kernel has speeds at different increments. 1036 will probably be as close as you can get to 1024.

First off i take no credit for the virtuous oc daemon itself, it was developed by rmk40.
And credit goes to -viperboy- for the idea, i used his rom and really liked the oc daemon and saw the difference it makes. Check his rom out here. It has a nice interface to control the oc daemon and other features of the rom.
You can get more info here
DON'T use any apps to adjust cpu with this ie., setcpu, cpumaster, etc.
Ok, here is the deal flash the zip file the script will run by itself the only adjustment you have to make is the virtuous oc settings. This should work with any rom and probably any device i just don't have any other devices to test it on.
Here is how:
Open root explorer (or whatever file manager you use) and navigate to /system/etc/virtuous_oc, you will see 6 files named:
sleep_governor
sleep_max_freq
sleep_min_freq
wake_governor
wake_max_freq
wake_min_freq
These are the files you edit to your liking, i only edited wake_max_freq to read 1836000 or 1.8ghz
The two governor file have different settings and they are:
conservative
userspace
powersave
ondemand
performance
Again edit to your liking i left them ondemand myself seems to work good. I don't really know what the settings do exactly when it comes to these but they seem pretty self explanatory.
To see if it's working all you need to do is open terminal emulator or adb shell and type one of the following:
Current CPU frequency
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Current CPU governor
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Current min CPU Freq
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Current max CPU Freq
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
It autostarts using init.d, so MAKE SURE your rom supports init.d, if it doesn't you can still use it but it has to be started manually by entering the following in terminal emulator:
Code:
/system/xbin/virtuous_oc
If you overclock MAKE SURE your kernel supports it, I'm not responsible for any damage incurred
In the future i want to make an app to control the settings but i am still learning that part.
Big thanks to rmk40 for this awesome daemon and -viperboy- the bad ass idea !!
EDIT:
A basic rundown of the oc daemon is it scales up your cpu when you screen is on and scales it down when it is off, so your cpu is not overclocked continuously. It does save on battery as long as you don't get crazy with the overclocking.

There may be some extra ones not listed here. From doing basic math, it seems you have to go up or down in increments of 54,000 when adjusting the CPU speeds. So if you want to UC higher than 192000 but lower than 384000, then you SHOULD be able to add 54,000 to 192000 and use that, or subtract 54,000 from 384000 and go that route.

Basically you can set them to what you want within reason, the way i do it is
1836000 is 1.8ghz
1188000 is 1.1ghz
So if you just put a . in between the first 2 numbers its roughly the ghz so
1288000 would be roughly 1.2ghz, at least that's my understanding if i'm wrong i'm sure someone will correct me. I wouldn't go crazy and set it at 2288000 that might do some damage.
Woooohooooo!!!! Im going in. Thank you sir!

Actually, 1288000 is 1.3 rounded up and 118000 is the stock 1.2 speed, but I get what you're saying.......maybe I didn't do a good job of explaining myself. If you want 1.5, you can't set it at 150000......you'd have to set it at 1512000 (or something like that) because it must go up or down by fixed increments. I don't remember what the exact increments are, but I can look it up and post it if you'd like.
Edit: The frequencies are:
Underclock: 192000 384000 432000 486000 540000 594000 648000 702000 756000 810000 864000 918000 972000 1026000 1080000 1134000 1188000 (stock)

I haven't tried using this method yet, as I'm already OC'd using viperboy's script. Maybe someone else can test this and confirm it is accurate.

SetCPU can take up to several seconds to adjust, and it uses RAM also. A Daemon is instantaneous, and uses little to no RAM.

This is developed by Virtuous Unity for stability in OC the CPU, Set CPU uses some voltage to run and has been known to be unstable at times, this is the most stable way to control OC frequencies right from boot.
The Daemon works great (I have a version of this I'm testing on the MT4G at the moment) and there are benefits to using it, I would have to say it's important to spend some time reading information on Kernels to better understand what your using and the risks behind it.
Found Here: http://forum.xda-developers.com/showthread.php?t=1143177
( Scroll to the 4th Post for full information on the Daemon )
State-of-the-art-solution
So we (more precisely rmk40) thought of a better solution.
He wrote a native C Daemon which changes the governors instantly without any lag.
This leads to major performance improvements right after turning on the screen and in the lockscreen.
But at the moment this solution is a little bit harder to configure. We are planing to make a GUI for this, so you get the same comfort as using SetCPU.
Nevertheless you can even now adjust the daemon to your needs.
Be aware that the daemon only works if all CPU tuner apps are deinstalled. Otherwise it deactivates itself.

No worries.........glad I can help with the little stuff. However, it seems like basic math is too hard for me. The correct increments are 54,000 and NOT 48,000. After some careful review, some of the high end OC frequencies had typo's, as well. I changed the info in myl post, but please update the OP, as well. I'm sure most people will be referring to that.
Just set this up on Rewind 2.1 and it appears to be working awesome.. definitely seems smoother then using a screen off profile in setcpu..
What I don't get is why Google doesn't incorporate something like this in all Android builds. It seems there are many things that can be manipulated to improve battery life on Android devices but that these solutions are just being ignored. Anyhoo, I don't think I will ever use SetCPU again...
Useless without voltage control
So this will work with nets kernel, and not against it? Just use it instead of setcpu?

It definitely isn't useless without voltage control. I don't see how saving battery and using no system resources is useless. Plus, you cannot edit voltages on the E3D kernels yet, the sysfs HAVS interface needs to be implemented first.

As the title says, would like to gather your ExTweaks settings. Always looking to improve battery/performance.
What is ExTweaks? From the makers of Voltage Control & SiyahKernel comes a highly configurable kernel tweaker. Requirements at the moment are SiyahKernel 2.6.13 or Entropy's DD 3/5/2012 +. It allows you to change such things as CPU Hotplug, GPU Steps/Voltages, Governor/Scheduler & much more.
Reference on what these settings mean: http://forum.xda-developers.com/showpost.php?p=23616564&postcount=6
Post in whatever format is easier for you. I am currently just listing them from start to end. Here are my current settings: (init.doh 0.4.6b & Siyah)
CPU Tab:
CPU Hotplug Default/50/90/80/100/200/600/1000/600000/AFTR+LPA/0/2/2/2
GPU Tab:
100/160/200/800/850/900/90/55/90/70
Screen Tab:
7/20/0/24
Misc Tab:
Unchecked/500/ondemand/sio/stock
I am aiming for battery with the above tweaks. So what are you currently "rocking"?
Just a heads up, Entropy's DD has been updated (3/5/2012 and Up) to run this also.

That is correct. The idea of ExTweaks is to provide a "universal" configuration app.
Files in the kernel initramfs itself define nearly everything in the user interface - each tab, and each item within a tab.
I can tell you, for example, that the CPU screen has some significant differences from Siyah in my kernel, as I have decided not to include Tegrak Second Core support (It's redundant - the only thing that can't be done with the existing interface is to force the second core on, which is kind of pointless and bad for power management.)
The GPU interface should be nearly the same, but it might change in the future. I'm thinking of changing the down thresholds to "step down target" - Instead of defining it as the percentage load at the current frequency, define it as the target load at the next frequency step down.
I have at least one additional option in misc (Per-File fsync() control) that isn't in Siyah

I didn't have time to revisit things, but I'm fairly certain, as I mentioned in that thread, that the test was flawed - Plugging in USB appears to fire enough interrupts to block AFTR and LPA from ever getting entered. As a result, one of the bigger power penalties invoked by activating the second core (blocking AFTR and LPA) has already been taken in his tests.
I set second core kickin threshold to 1000mhz and I undeclock to 1000mhz. I set gpu to 100/100/100 @800/800/800. Ondemand governor and noop scheduler.
How is this working for you? Notice ant difference in battery?

In my opinion, 800 is probably the best place for second core kickin - from 800 to 1000 is where voltage starts rising quite a bit, so you get more work per unit of energy when kicking in the second core at 800 than ramping up to 1000.

In any event, I'm really appreciative and glad to have a new venue to futz with on my phone. I can't wait till I learn what to tweak to get it running at optimal performance. *Not to say these phones are slouches at all though.*
Thanks for sharing your settings folks! Thanks for the information too Entropy.
As for your voltage control settings, ignore the GPU tab in that (He will be removing the GPU tab soon). Just use Voltage Control for changing you CPU voltages & min/max freq. Can also change your gov/scheduler, but ExTweaks does it too.
Please note whatever you save as a startup in voltage control will overwrite whatever conflicts there are with ExTweaks (Gov/Sched/Charging etc).

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.
Hi all, I'm happy with LOS performance during light and medium tasks, but my device stutters more than I'd like during heavy tasks (e.g. maps, waze, etc) and app switching. Since battery life has been great, I'm willing to sacrifice some SOT for a more buttery UX. If that's even possible...
I started by changing performance profile from balanced mode to performance mode... and I can honestly say I don't notice a difference.
Now I'm just starting to experiment with changing the CPU and GPU governors using Kernel Adiutor. I've changed both little/big CPUs and GPU from interactive to performance. I'm not sure how to measure the results, but my feeling is that all around performance has increased, but the device still struggles with heavy tasks and app switching.
Anyone else have success tweaking? Please share your methods

Hi,
Use may be a custom kernel to tweak more.
And here a thread to know about tweaks:
https://forum.xda-developers.com/general/general/ref-to-date-guide-cpu-governors-o-t3048957
The best perf i got is with CPU gov bluactiv and io schedulers tripndroid.
But i did not tweaks all possible values.
I guess a lag will always be present as we have 2gb RAM phone
Disable fsync, set governor to darkness and scheduler to maple.

you can use custom kernel and increase performance
i set my governers to lionfish and disable fsync and i/o sceduler to maple its works great

Thanks both for the replies. What kernel do you use? And is there a trade-off when disabling fsync?

You can search for it for more info. But TL;DR, fsync prevents data loss when a sudden power outage happens. For example, you are saving something then you accidentally restart your phone for some reason, there is a chance, repeat, a chance of data loss. A whole year of having it disabled, I haven't had any loss.

Was working in parallel thanks for the TL;DR. For anyone following this thread, here's more info fsync https://forum.xda-developers.com/showthread.php?t=2244162.

using HD kernel with spectrum..its pretty good,,
new Astral kernel is looking good..its in beta stage but working perfectly fine

changing data and cache partition to f2fs make it really smooth.
and with HD kernel it makes it even smoother.
Again for anyone following, here's a link to popular HD kernel for Honor 5x, https://forum.xda-developers.com/honor-5x/development/kernel-hotdog-2-0-1-t3544887
While gaming, set the governor to performance for maximum smoothness.
