I see alot of people here claiming to have 6 hours of SOT on regular basis.
I dont see that is possible unless the phone is running whole day on 0% brightness with airplane mode on.
Is there any trick I'm missing on or what?
yes, root your device, install trickster mod, and put your cpu with noop and governor ondemand and min. 374mhz max. 1574mhz, and your gpu on powersave profile with 330Mhz on GPU! and of course lowering the brightness depending of your needs, if yu are outside you need to raise it, but if inside you can lower it!
i have ~6:40 OST with that settings

no, my performance is good, no lag, no nothing...i cant see any problem with my device...with this is perfect to me!
i'm not a gamer, so i only play casual games on it and use basic stuff like music, camera and web browsing...and i tell you: my performance is superb!
because i have my phone bloat free, apllyed some mod's to build.prop and etc etc, is not only the trickster mod who gives to my phone this performance even with this settings!

Hi to all,
Yesterday I flashed a Bindroid Rom.. it seems to be very very optimal for battery consumption.
And then, to improve battery consumption, I would know:
1 - setCPU or similar: in wich way must I set to improve battery charge? (I don't interested in performance, velocity, reactivity, but ONLY on battery consumption on my DHD)
2 - setCPU or similar: what mean governor settings?
Thanks a lot

Try ocbeater apk, seems to be simple..
To reduce battery consumption on your DHD, you might want to know exactly what each governor do. Usually it is set to ondemand in default. Ondemand raise the cpu speed gradually based on system workload. It is a balanced governor for speed and energy saving. You can adjust its threshold value and powersave bias to suit your needs.
For more energy saving, it is recommended to use conservative as your governor. It tends to reduce the cpu speed below the actual need. In other words, it sacrifices performance for more juice for your DHD.
Edit: Powersave governor is not recommended as it will force the cpu speed to the lowest speed available which mean super lag.

Yep, that would do just fine. Also, adding a sleep/wake profile can boost the battery life even more. Then observe and compare the battery life between now and then. Try to play with the app and fine tune the settings to suit your need.

Given that I have never use OC/UV Beater, I don't know exactly the setting is, but I could tell from the pictures that it has no sleep profile. All the other configs are all correct.

The link is broken. What I meant earlier is your "sleep" profile is somewhat set on battery low trigger, not screen off.

Rooted Stock ROM. http://forum.xda-developers.com/showthread.php?t=2387942. Havent changed my Kernal asfar as I know, but have adjusted CPU setting in ROM toolbox.
I currently use OnDemand governor with max slider at 1200Mhz. After learning that OnDemand is not too good for batterys life long term as I use my phone in short bursts and alot of multitasking I have found that SmartassV2 would probably be the best governor for to use. The phone is used to play media, games, browsing and sketchbook app, nothing too serious but I want the best balance between battery life and performance possible.
I understand playing with the kernal can result in issues but have not managed to find a guide on how to do this on XDA. Can anyone advise me on this or point me towards a simple guide please.
Thanks.
so ur using Stock Samsung kernel with ondemand ??
only governor on stock kernel that have cores hot plugging is pegausuQ AFAIK so ondemand will cause worse battery
GUIDE TO EXTEND YOUR BATTERY LIFE UP TO THE LIMIT
20% Enough For A Day!It is one of the best option if you left home with less juice, and are going to be in a trouble!
Yesterday, when I was on a trip with my friends, I forgot to charge my battery, and guess what: just 17% of juice left on my device at early 6 AM! So, I used this simple method, which I am going to explain down there, then while returning home at 9:30, 6% of juice was available!
The thins that I did was, listened to music for more than 10 hours (via earphones), Took photos for more than 15 mins (altogether), Surfed 3G for about 7-10 mins (on way back to home! ), and some phone calls!

App required:-
No-frills CPU Control: Most of the custom ROMs have this app integrated, but you can also download from Play store! https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
STEPS:-
1. Go to No Frills Cpu Control or Cpu Settings(on most ROM's settings)
2. Select:
-Ondemand (Extreme Battery life)
-Powersaver/Conservative (Ultra Extreme battery, but laggy)
3. Tick Apply on boot and choose Apply!
4.Youre done, Enjoy ur maximum battery life!
-P.S: To have these governer, i.e. "ondemand/Powersaver/Conservative" you must be on Custom kernel bcoz, its not available for stock kernel!

well for your kind information all the governers (if have custom kernel) take phone to deepsleep while screen off. And as per your thread title i don`t think the guide is that effective becoz this governer thingy is known by almost every one here.Not trying to flame but just wanted to say that don`t open new threads for such known things.
stock kernel have 2 governor
bcm21553 and performance
this trik can be apply when we use custom kernel
i know about this long time ago

You can underclock with stock kernel if I know correctly.
The stock oreo kernel of a520f supports these features and it should apply to (Exynos) most custom kernels, all devices across A 2017, and most related devices.
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq - Max clock of cluster 0, reduce to underclock the CPU.
/sys/devices/system/cpu/cpu4/cpufreq/scaling_max_freq - Max clock of cluster 1, reduce to underclock the CPU.
/sys/power/cpufreq_max_limit - Max clock of both clusters, more forced once permissions are set, watch device temperatures.
/sys/power/cpuhotplug/max_online_cpu - write a number 1 to 8, it is the CPU cores that are online.
Maybe relevant:
/sys/class/misc/mali0/device/dvfs_max_lock - GPU clock, more forced once permissions are set, watch device temperatures.
/sys/class/misc/mali0/device/core_mask - The GPU core combination in use, write a number 1 to 7.
/sys/class/misc/mali0/device/dvfs_governor - GPU governor, write a number 1 to 3.
/sys/class/devfreq/17000010.devfreq_mif/max_freq - could affect cellular and wifi
/sys/class/devfreq/17000020.devfreq_int/max_freq
/sys/class/devfreq/17000030.devfreq_disp/max_freq
/sys/class/devfreq/17000040.devfreq_cam/max_freq
The CPU governor is with scaling_max_freq though only userspace performance interactive.
Reboot to undo changes.
Edit:
/sys/devices/system/cpu/cpufreq/mp-cpufreq/cluster0_max_freq
/sys/devices/system/cpu/cpufreq/mp-cpufreq/cluster1_max_freq
Though this should not exceed the max clock, in addition to the governor's settings(/sys/devices/system/cpu/cpu[0-7]/cpufreq/interactive/...), the CPU clock is boosted temporarily when the screen is touched, the activity is changed, etc, even when it might not be needed. It's often "touchboost", and could be disabled by enabling medium power saving, or,
/sys/power/cpufreq_min_limit (home, gesture, scroll, app change, unlock)
"644 permissions" - disabled
"664 permissions" - default
check its contents after changing, should be the CPU min clock.
/sys/class/input_booster/level (touch, long touch, multiple fingers, etc)
0 - disabled touchboost
1 - low
2 - default
3 - high
might need the permissions being 464
CPU 4-7 needs to be powered on before cpufreq becomes available in its folder.

Instead of what I understand, with the normal app type cpu master, or no frills cpu you can not change the clock of the CPU and the governor, but with the app Kernel Adiutor, recommended by @iloveoreos is possible, it is very strange this thing. However, despite the underclock of the CPU you can not then earn so much battery, it seems void

It doesn't count that much because you rarely use the cpu max freq. Maybe try underclocking the gpu too, if you can but probably not and there's not much else to do

The cpu and gpu are managed by the OS and its resepective governor settings. Little will be gained by reducing cpu cylcles unless it's correctly managed.
The single biggest battery user is the screen. Either reduce the brightness to the lowest you can stand and limit its on time or use powersave mode which will reduce both screen and cpu/gpu frequency.
Also selecting a more suitable governor helps.
If you frequently use high cpu usage apps its pointless using a conservative governor as you'll just lag the device. An ondemand governor would be better suited.
You can also set apps to be killed the moment you leave them in the developer settings.

The problem is that with the only governors we have in stock are interactive, performance and userspace. The kernel allows me to just adjust the cpu, and on android oreo we do not have custom kernels that allow me to do anything. So in addition to lowering the brightness, really there is nothing that thanks to xposed and the root that allows me to do at least 5 hours of screen? The upgrade to oreo ruined everything, Nougat was too perfect
i've been using this phone for about 2 years now and recently moved (about a few months ago) to using a custom rom (crdroid 7.1.2). it was running smooth and cool until day the clockspeed decided to lock itself at 2000 MHz (checked using cpu-z). I do not know if this is normal but the phone's temperature goes up to 36C on idle. i thought the problem was with the Lspeed app (+custom kernel) so i uninstalled it but it didn't work. I also factory resetting it, but still not luck. will updating the firmware resolve my issue? if not, what other available solutions are there?

If you are using Fast Charging, that heating is entirely normal (happens to me too)
But heating during idle is not normal. Try changing CPU governor to something else. (like schedutil or powersave)

use Rootify, select the CPU tab located at the top then change it.
The app sometimes gets stuck at Loading screen though.

ok so it does work when i change the cpu govenor, but the only option that actually works is 'powersave' (as well as 'userspace'). all the other ones still sets it to 2GHz. 'userspace' seems to have a somewhat of an improvement but it's only setting everything to a constant value. is there a way have it set to balanced mode?

powersave forces the processor to work in the lowest frequency availible, thus consuming less power.
userspace allows the app to set the CPU frequency whatever it wants. This isn't supposed to be used in Android since changing CPU speed thorough an app is super uncommon.
Others like ondemand normally keep the power low but starts using the higher frequencies if a processor intensive app is launched.
You can learn which governors do what in this post so you can set the most suitable one for you.
