Hello,
I upgraded to the new S20 since tuesday but it seems my S10 at same screen definition FHD+ and 60Hz refresh rate was lasting more in real daily life use, phone, chat, surf on wifi or 4G.
I wonder if the battery will improve within the next days or if I should keep my S10 to get a better battery life.
I just don't want to buy a new phone with less battery life .
Kind regards.
the 120hz refresh rate screen is affecting the battery performance pretty drastically. I read that you get 30% more screen-on time on the S20 when it's configured to 60hz.
I believe that you should compare between the S10 and the S20 while both on 60hz and decide according to that.
on daily basis you can use 120hz and on days that you need more battery usage - move to 60hz.
Already did, thx

Technically the Mediatek CPU supports the 90hZ refresh rate, any idea how to turn it on!?
Technically the refresh rate is all about the screen, gpu and display, not cpu...
So could a mod be available for it!?
Just like the mi9 had!?
Which consumes more battery : 120 Hz, FHD+ or 60 Hz, WQHD + ?

Mate it is known that 120 Hz, FHD+ does consume more battery thats why Samsung standard setting is for it to work in that combination.
My question is between the two, which combination consumes more power.

It's 120 Hz, FHD+ that consumes the most
Anything using 120hz will consume more power, even if it's just HD+ with 120hz, it will use more than QHD and 60hz.
Using full screen resolution barely uses more power at all then the lowest setting actually, but you get HOURS more of screen on time using 60hz than 120hz.
This indicates that qhd hits the battery the worst.

Not more than 120hz does.
I'm speaking from experience, not an article.

Seems testing was performed
not anecdotal.
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

In our review, the Vivo X80 attempts to impress with a quad camera, Snapdragon 8 Gen 1, ample storage, fast charging and probably the largest, fastest and most versatile fingerprint sensor.

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.

Yeah me neither, still shocked how slow it is compared to any phone, actually.

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!
