is it possible to reduce screen resolution in android? so as to save power or play games more smoothly just like on a pc for example?
There's an app for Froyo
http://forum.xda-developers.com/showpost.php?p=7938982&postcount=1
will reducing resolution actually increase battery life or play games more smoothly or i am being wrong?
anyone? .........
thread up..........anyone?
As for battery no. The screen is still lighting up the same amount of pixels and same brightness etc... Gaming i doubt u will see a difference. Tell us if u find othwise tho. Hope that helped

Changing screen density isn't the same as changing resolution. Apps choose which icons to show depending on the "screen-density" value reported by the device. So higher density devices will have larger and more detailed icon graphics, etc.
As far as saving battery life, the screen typically uses most battery which varies slightly depending on the brightness setting. One root user found he could save battery by only showing red colours (requires changes to the display driver).
Shrinking the screen like in Note 3 will save energy...anybody found a way how to do this in other phones? application?

Dynamic Display is an app for Samsung Galaxy S20/+/Ultra that allows you to set a display refresh rate for certain apps.
The app does not require root, but it does need a permission granted with ADB.
Dynamic Display is only intended for use on Samsung Galaxy S20, S20+, and S20 Ultra. Other devices with 96Hz or 120Hz display might work, but nothing is guaranteed.

Hello @ cr5315
The idea is interesting, but he was unable to set the refresh rate to 96hz
Example:
Chome at 60Hz = In the test it stays at 60Hz (great)
Chome at 96Hz = In the test it stays at 120Hz (why?)
Chome at 120Hz = In the test it stays at 120Hz but when switching between applications, it returns to 60Hz
Sorry about my English.
Have a nice day.

Did you root your device? If no, you can't use 96hz (even with ADB).
Gonna check this app later on.
I can use 120 96 or 60hz not rooted lol.

Hello,
You did an excellent job on your application, I tested it works very well on my S20 +.
Thank you so much.
But you can not put a filter option? to separate system applications and User Applications ?

What did you put in for the adb command please tried what the app tells you but doesn't work?i had the previous version of this which worked fine but on this latest i cant get past the adb commands
Just gave it a shot, but somehow doesn't seem to work/stick here?
I set 60hz as the default mode, and force Edge, Gmail, Whatsapp, Nova Launcher to 120hz.
However, scrolling through gmail, nova, whatsapp doesn't feel fluid and going to testufo.com on Edge it shows 60hz. If I reload Edge and/pr the page I do seem to get 120hz, but switching between apps and going back it seems to be 60 again.
So I can't really seem to count on it, any ideas?
For now I'll just go back to the 'default 96hz' option from another app.
version 1.0.0 thanks! tried and working 96hz.

OMG! What an awesome app. Just tried in my S20+ and it's working. I was wondering if it's possible to force 120Hz with 1440p, but that's hardware limited right?
Anyway, thanks a lot for this great app.
That's correct, the display physically cannot do 96Hz or 120Hz at 1440p

update bixby routines, now it has a routine that changes resolution and refresh rate
If you have stock MIUI or EU rom and you want to use 90hz instead of 120hz to save a bit of battery, please read this guide carefully.
Steps to follow:
1. Set your refresh rate to 120hz
2 Download and install SetEdit from the Play Store or as an apk.
3. Switch to System Table
4. Find "user_refresh_rate" key and change value to 90
DONE!
You can check the screen refresh rate by using the Power Monitor on Development Settings.
This setting will persist even after reboot. Just don't change the refresh rate in settings.
Thank you!:fingers-crossed:
Try that and not lock at 90....seems like dynamic moving from 90 to 60 to 120.....i though it supposedly to stay at 90....
Custom Rom Or Root only.
Thanks man it works

It's working. What MIUI region build you got?
Working on mine, I got the MIUI region global version.
Stable at 90Hz. I'm checking it using the power monitor tool.
Thank you.
No such key in System Table.
The option does not exist

Latest global 12.0.3... It's not fixed 90hz...
it's working for me Global 12.0.3
Hi, it seems in eu_global Roms key is missing. Just add it.
In the EU Rom you can just add the key "user_refresh_rate" with value 90, Power Monitor will show 90Hz.
Thx OP
Edit :doesn't solve the Problem with dynamic refresh rate in games though.
It works just fine. Looks like the screen refresh rate is h̶a̶r̶d̶ locked to 90Hz.

It actually gives you an option to use 90Hz refresh rate in place of the stock 120Hz as OP said in the title. Maybe to save the battery and still have a smooth experience. Doesn't make that big of a difference either way imo.
It just doesn't work, I set the frequency to 120Hz, installed this app, set the value to 90Hz, checked with the monitor and it was fixed at 120Hz

Make sure you gave the app permission to Modify system settings. It works for me even on 12.0.4.0. Global. Had to do it again after the update though.
Thanks op. Miui 2.0.4 global. Worked as expected.
12.0.2
Installed setedit
Changed 120 to 90
And it does not work
Even after checking developer options display monitor
Do I need to be rooted or something?
No luck for me. Stays on 60hz with low frame rate. Might reset an try a reboot
Worked after a bit of playing round an a few reboots. Not every application or game is 90hz or 90fps.
But can include when it worked with 'bullet Force'.
Thanks works ?
Tks.

About this app:
Refresh Rate Mods
Change default refresh rates
-Easily change the overall refresh rate settings of devices supporting multiple refresh rates.
-Set supported mid refresh rates as the maximum refresh rate limit for battery savings (e.g. 96hz instead of 120Hz).
-Quick settings shortcut
-tasker plugin support.
Motion smoothness mode switcher(Normal, Adaptive or High)***
-Apply adaptive mod on device that don't natively support adaptive mode [premium]
-Tasker plugin support.
Per-app refresh rate settings:
Set different refresh rate settings for every app either adaptive or fixed(stationary) [premium].
Motion smoothness on power saving mode (not working to all devices with OneUI4.**+, test first). ***
-GMH will apply a workaround to bypass 60Hz limitation on Power Saving Mode (PSM) on supported Samsung smartphones.
-Automatically apply workaround when PSM is enabled [premium]
Screen-off Mods:
Force to Lowest Hz: Force the lowest refresh rate on screen-off or Always-On Display(AOD). This overrides Samsung's strange stock behavior which sets the refresh rate to the highest on screen off (update: it is now at 60hz since OneUI3.0) to improve standby power consumption a bit.
-Tasker plugin support
Auto apply power saving mode during screen-off (after ~ 10 secs)***
Auto disable Autosync***
Quick-doze mod
-Quickly enter doze mode during screen-off that can not be interrupted by motion [premium].***
-Tasker plugin support
Auto SENSORS OFF (experimental non-root workaround)
-Device sensors will automatically turn off while screen is off until the device is unlocked to help minimize battery-draining motion-triggered wakelocks while device is not being used.
-Tasker plug-in support
Others
Battery protection mod (Experimental)
-Option to set maximum charge to 86%-95%(for OneUI4+)[premium]
Quick resolution switcher
-Easily switch to any supported resolutions using the included quick setting tile***
-Tasker plugin support
Customizable refresh rate monitor
-Use statusbar or overlay which you can place anywhere on screen.
-Tasker plugin support.
Net speed statusbar indicator
OneUI inspired UI. Dynamic theme and Icon. Manual language selection
Note: The premium license is on a per device basis (not per user).
***these marked features require a one-time ADB procedure (this is not root)
Galaxy Max Hz background service is highly optimized. Background battery usage p is very negligible .
Info: This app targets older android sdk in order to control refresh rates without ADB setup or root. Just tap OK the dialog that says "This app was built for an older version of Android...." when opened for the first time. If OK button is not visible, just tap the blank space on the lowest portion of the dialog.

How to setup GMH with Tasker?
Create(+) a Task in Tasker app and give it a name. Inside the Edit Task window, add GMH action by clicking (+) button > Plugin > Galaxy Max Hz. Click the (edit) Configuration section to see the tasker settings/variables available for GMH. Set a value to each of the variable that you want to apply by clicking (+) button > Variables >Variable Set > enter the variable name and a corresponding valid value. Ensure to put Galaxy Max Hz action task after all the Variable Set tasks (use hold and drag to re-order).
You can then link this Task to the Profile/Trigger that you want to use. You can create multiple GMH tasks with different variables.
You can also use GMH Tasker plugin to exclude apps from Adaptive mode.

This app does not work on the Galaxy A52 5G. It keeps showing 60/90Hz as the toggle, does not show 120Hz at all.
Same for me, only 60 or 90Hz.
And there is an alert window on startup, that it's developed for an older android version
Tested with v7.10.00_beta
same for me, only 60 and 90hz available, but 90hz doesnt work at all, so it defaults to 60
Hi Dev,
Tested out your app and granted every permissions needed.
turns out that the app does not support 120Hz refresh rate.
I tested out the 90Hz and checked if it is working but that doesn't work either. it defaults to 60hz right away and does not let me choose other refresh rates.
Thank you for your Program. Hopefully a fix will come.
looking forward for this to come to A52-5G

Hi. I uninstalled the previous app thus, deferring me from the previous adb command and i have no pc near me at the moment. But the options for the screen refresh rates are just 90 and 60. I also tried both adaptive and high before i uninstalled it before and had no luck.
Please see screenshot below.

Wow. Thats fast! Appreciate it a lot.
Will give feedback once i tried it out when i get home.
Tried it a while ago and its working well now! Great job. 60hz and 120hz adaptive screen refresh rate now working flawlessly. Will keep supporting you on your apps. God bless!
Suggestion: hopefully we could see a shorter time for the adaptive to kick in. (Like a second or less).
I dont know how adaptive works at S line series of units but feel free to correct me if im wrong.
God bless!

You cant really see the difference right away if youre doing a lot on your phone as it makes your screen go back to 120hz.
But when you use it to the apps that doesnt need touch, like watching movies, video calls, the savings are significant.
I used in a 21 minute video call and it only consumed around 2% batt

there is an app called "setedit" in google play store, with it you can enable some apps to run on 120fps but as i said it doesnt enable 120fps in all games, all u have to do is find "peak_refresh_rate" click it, click edit value and then set it to 1
In RMX3301_11.C.16 version they added custom app refresh rate, so when you select high refresh rate instead of Auto select you'll see an option to change refresh rate per app and you can change your games to use 60, 90 or 120 hz, worked for me in Minecraft.
World of Tanks set to 120 Hz and the application runs at 60 Hz.
Spoiler: Screenshot
Edit:
I was able to set it to 120Hz.
I changed the default 120 Hz to 60 Hz, confirmed then put 90 Hz, confirmed the change and finally 120 Hz and confirmed the change. I launch the app and it runs at 120 Hz.
