Coming from PC gaming , I can push my TV/Monitor another 15fps , so it was 60Hz and with overclock its Now 75hz , not all TV Monitor can do this , its a matter of playing around until screen goes blank , is it possible to overclock the OLED screens refresh rate ? On the Samsung phones, im not a dev , ,but willing to test if theres a possible way, im using s9+
Kind regards
That would be a nice if it is possible even a small bump would make good difference i believe
It stays at 60 fps. Testing it a few times

There are bunch of websites which work reliable.
just google it.
It has been done on few xiaomi devices. I believe s9 displays are really high quality and theres really chanse that they can handle more than 60hz. I would trade resolution for refresh rate

Honor 8 Pro is an incredible device, which ticks all the boxes. But since it has a 2k display and a v8 engine in it, it chunks on the 4k battery pretty quickly.
If there is some way, we could lower the resolution to 1080 similar to that on S8 and S8+, I think the battery life will almost double!

You can there is option in battery section when needed it automatically lower the resolution !!!
We actually don't know when it gets activated. It would be better if the user is given better control of the resolution! Like to lock the display on 1080 to preserve battery and then to switch the display to 2k while playing HD games or watching VR
Charging time more

like others have mentioned, ideally, we want something we can manually control. like what is found on many other phones with 2K screen... users can manually select between 2k, 1080p and even 720p.
right now, the one under the battery/ power savings... we don't even know when it gets activated... or if it works (coz honestly, i can't tell any diff between 1080p and 2K on such small screen).
Hi,
Although there is a option to lower screen resolution to reduce battery consumption, we don't know when it exactly kicks into play or if it does at all. I suspect it only reduces the strength of the pixels.
We have raised this query in the recent meeting which was held in Chennai. They took it with a nod, not sure if it will be implemented. We did point out as to how S8 and S8+ does it.

You will see when an app which sucks too much battery , during that the pixel will be decreased.
PPSSPP needs this...
Current emui 5.1 low res option are not decrease resolution to 1080p I think. Its just reduce the pixels a bit and automatically activated only on power hungry apps. Logically if change resolution at least your screen will flicker a bit. Dont worry upcoming emui 8 will have option to truly change your resolution either 2k, 1080p and even 720p. I think its coming to our phone in January.

The settings allow you to lower the resolution. I lowered the resolution to 2340 x 1080 and I don't really notice anything different.... Would this increase battery life? If so, how much?
It will definitely increase battery life.
How much will it increase depends on your usage and your apps installed. It should at max give you 10% increase.

It is well and widely known that lowering resolution won't give you increased battery life. At all
Ah thanks. I come from an xperia z3 so been using FHD screens only. I was interested in the XZ1 compact back then and one of the key points from reviewers is that the lower screen resolution(720p) saved a lot more battery vs the XZ1 at 1080p.

I think the misconception is lowering the screen resolution vs a device that maxes out at a lower resolution. Maybe it makes a difference for OLEDs...but for LCD screens, all if the pixels are still illuminated, so there's not much difference there.

[Dopey voice]"Bruh...look what my phone can do to save battery life. Can yours?" [/Dopey voice]
Using lower resolutions use less power bc they use less gpu computational power. Youre not saving anything really from the screen itself. Think of it this way does your computer/laptop use more power running resource intensive applications or running idle?

Not that the resolution that saved power. If Sony could put their 3840x2160 resolution display into 4.3" size of XZ1 compact it still would run longer on battery than any 6.5" sized phone from similar battery even with 720p display. Because it's sheer size of screen that saves battery, not the resolution. 4.3" vs 6.5" is hefty difference. One needs more light to make 6.5" display emit light than to make 4.3" one hence one need more power.
Think about it this way, if resolution would matter then XZ Premium and XZ2 Premium would drain their batteries in a matter of minutes with 3840x2160 res displays. Right? But they work almost as long as say Galaxy S9 Plus or Note 8.

It not works like that. When your phone renders picture in 720p or 1080p it doesn't do it sitting idle. It still consumes power when rendering picture 60 times a sec. And its GPU still runs at 200MHz, maybe it needs like 230 or 250MHz for rendering picture in 1440p but is 250MHz vs 200 MHz a huge difference? I doubt it
It's not like 1440 picture rendering needs full GPU power but 720p or 1080p can be powered by idle GPU. Never was, never will. Ask devs in http://forum.xda-developers.com/android/software-hacking if in doubt
In reality ability to pick your resolution for battery life is a gimmick and doesn't really do anything.
There were no proofs that phones live longer from same charge when it's resolution lowered. Maybe it works for constant gaming, like playing games in 720p on a 1440p screen will bump battery life. But in other cases no
Taking only power consumption from the display alone, there is no different between HD, FHQ, QHD. The different is that if a game or any apps(or even system app itselfs) runs at HD, it will need less graphic computational power than running at QHD (once again, its not about the drainage from the display, its from GPU).

in reality, it's bull****. learn how GPU works. Try to ask Google devs if you don't know. They do habitate here, at XDA
It's not like it renders something and then goes to sleep turning cores off as CPU does. Instead GPU renders frame 60 times a sec and uses 203MHz either your resolution is 720p or 1080p. It can't lower frequency to 100MHz magically because it's not designed that way. So it consumes as much power working at 203MHz either rendering 720p frames or rendering 1080p frames.
Hence no battery economy achieved

All setup. Now to go through some testing.
My biggest fear are all the heating videos on YouTube. I see in settings that auto screen refresh rate has the phone constantly refresh at 120hz!. So you basically have 120, 60 or 144hz, each staying constantly at those refresh rates. I'm not happy about that. 60 it is then. No wonder it got so warm during setup but now at 60 it seems OK.
It's lighter than I expected. Tired of heavy phones. I have a toolkit and sealant on the way. If heating is an issue I'm gonna open up the thing and give it some liquid metal thermal paste treatment. Lol what not. The phone was fairly cheap at £500
I read auto changes in some rates. 48,60,96 and 120.
And screen have a good quality?

No. Auto is a constantl 120hz. That's not good. No wonder YouTube is reporting bad battery life.
I blame android 12. My pixel 6 pro had terrible refresh rate control too
This may seem too obvious but think about it. Turning on show refresh rate option shows you a continuously changing refresh rate 10-24-30-60-120 Hz . LTPO can bring down the refresh rate to 10Hz but that constant switching between refresh rates may be adding flickers not consciously noticeable but may have an effect on the eyes in long term ?
This is to save the battery but can eyes adapt to a such a high degree of variable refresh rate ? Does anyone know the PWM frequency of Vivo X80 Pro LTPO 3.0 ? I did check with a slo-mo camera and it does show flicker (black lines moving across the screen). Honor 4 Pro is claiming a LTPO screen with highest ever PWM frequency for eliminating flicker. Any insight into this will be much appreciated.

Honor has 1920PWM if i remember correctly, idk how much the vivo has.
But i'll break you a myth, the LTPO does NOT improve performance unless you maybe watching YouTube all day and even so.
So far all the smartphones that has poor battery life, including the x80 Pro, has LTPO.
Based on my use, i just use the 120hz and it goes down to 10hz when possible, coming from the Mate 40 Pro which has 60 or 90 only with no LTPO, the Mate 40 Pro had better battery life.
They is no eye strain with either of them if you sit in the proper angle, i haven't noticed anything anyway.

Thanks for replying. Firstly Congratulations for your ROG6 phone . LTPO may be saving a little bit of battery but there are many other factors especially SD Gen 1.
But I am worried about LTPO's constantly varying refresh rate. In my 2 months of usage of X80 Pro I had two or three episodes of headache which may be very well be coincidental due to other factors. It did prompt me to research more on PWM frequency of X80 pro and what effect does LTPO have on eyes.

That's a good point that no reviewer actually checked or researched.
I had the X80 pro for a month and never had any headache, you might be sensitive to certain PWM frequency.
If you can check the Honor Magic 4 Pro you might deny or confirm that.

I have no way to check magic 4. Also , I did not find a way to force 60 or 120 Hz on X80 pro. Tried adb command and SetEdit. At least locking it to 60Hz minimum will be good enough even though it defeats the purpose of LTPO.
Does anyone know how to do that ?

It should be under the display settings>refresh rate.
Don't choose Auto, choose 120hz, and it will be 120hz all the time unless there is no motion on the screen.

Choosing a refresh rate in settings just sets the maximum refresh rate. I would like it to be at least 60Hz at all times which happens in all non-LTPO phones .

If you trigger the "show refresh rate" at the developer menu, you'll see it drops from 120hz to 10hz quite often.
Even if you'll force 60hz it will drop to 10hz, that's just how it works.
I don't think you can put a threshold of 60hz as minimum as opposed to 10hz.

Right. That's how LTPO works but in other phones , it will stay at 60Hz even if it is static picture. The flicker at 10Hz could be more than 60Hz unless the PWM frequency is high enough. Am I getting it right ?

Indeed.
But Vivo hasn't published information about the PWM frequency, so we're in the dark for now.
There is a new Notebookcheck analysis of X80 pro, but the frequency is pretty low

I am on W30 funtouch OS 12.0.12.12 and I noticed that Show Refresh Rate is now showing 120 Hz all the time if 120 Hz is selected in settings. Even Youtube is at 120 Hz which is great. Even in Smart switch mode the refresh rate only toggles between 60 Hz and 120 Hz . In essence LTPO has stopped working and I did not notice battery drainage as such so I am happy also due to concerns on LTPO safety on eyes and the phone feels fast irrespective of whether an app supports 120 Hz or not
Hey, so I bought this phone around a week ago and while I love its hardware, I'm having real trouble getting it to move smoothly.
Specifically, I noticed that the screen drops to 60 Hz or less in many apps (confirmed through developer options), slowing down things like the drop-down menu as well. Now I understand that YouTube and most apps do not support more than 60 Hz: however, I do not understand why the phone slows down the scrolling and the notification menu as well. I previously had a One Plus 7 Pro that remained buttery smooth in the menus, even when running YouTube.
Is there a way to force the screen to 120 Hz for Vivo phones? I have tried a lot of the options which work for other brands (tried Setedit, ADB commands, SmartHertz etc), yet they do not do anything on the X80 Pro.
Did anyone manage to force the refresh rate in any way on this phone or on another recent Vivo phone? I haven't been able to find much for X80 Pro specifically.
None so far, and all the apps support 120hz unless coded differently.
On mine ROG6, ALL apps works at ALL the refresh rates, on the vivo however, Youtube and spotify stuck on 60hz no matter what, it's purely Vivo's fault and i hope they'll fix it in the upcoming updates.
I hope they fix it soon as well, my Vivo is laggier than a midrange phone in daily use, despite having stellar hardware and great results in benchmarks. Certainly didn't expect that lol.

I had to choose 120 Hz specifically, when I used "Auto" mode it was down to 60 Hz in e.g. Chrome/Brave. Now it's 120 Hz there. Only app I can see with 60 Hz are games and youtube.
Latest SmartHertz version now supports manual modes, maybe with forced mode it will work on Vivo. Try it!
