Depends on your device and a bunch of other factors. If you are trying to maximize battery life you are generally better sticking to 60.

If you are consuming 120fps content or doing some kind of mobile gaming that actually supports it, you may benefit from 120.

Thanks for the reminder. I was wondering why my phone was using extra battery for the last month. Looks like a recent software update toggled 120hz on. I did have it turned off. I just went in and turned it back off.

The first thing I always do is turn 120Hz off. The difference just isn't meaningful enough to justify the extra battery drain. On a PC monitor sure, but on a phone I really don't care if my feed scrolls a bit smoother.

Rip battery

For me its not worth the hit on battery. Mind you my phone screen is 3088x1440 WQHD+ capable yet I set that to 720p. Sure, the image is a tiny bit better at higher res but for me I'd rather have a stronger battery life than a marginally better looking image on such a relatively small screen.

why would I want my phone to lose battery faster?

Curious, on which phones is it called "Smooth Display"?

On my Sony Xperia 1 VI running Android 15, this option is called "High Refresh Rate" like a sane person would call it lol

In terms of running faster, saving power and preserving battery life, that reminds me that I turned off some stuff on my phone a couple years ago, and have been completely happy with the result.

Looking it up, I thiiink it went like this:

To disable animations on most Android phones, go to Settings > Accessibility > Color and motion (or Visibility enhancements) and enable the Remove animations option.

For more granular control, enable Developer options by tapping the Build Number in "About phone" five times, then find and adjust the "Window animation scale," "Transition animation scale," and "Animator duration scale" settings to their lowest values or off.

Before trying any of that, please do fact-check the above.

It's nice that it's optional (as opposed to someone else making decisions for you). Some people will appreciate the extra display smoothness while others will be fine with 60 Hz and the extra battery life.

I think this post made more people turn that setting off on their phones than the other way around xD

Yeah for some reason it runs on adaptive mode. For example longer battery life. Just turn on refresh counter and see how it works for better understanding, its all optimisation.

No. Battery is already too small.

I turn the refresh rate down on phones, where battery matters. I turn it up on desktops, where it doesn't matter.

I don't want over 60fps anywhere, ever, at any time. Rendering 120 or 144 frames per second is over twice as much to process, with no noticeable improvement.

IMHO the only reason to go above 60Hz is for better responsiveness in competitive games. Otherwise it's just a meme, definitely a total gimmick on smartphones.
