I'm curious, what do refresh rates like 60Hz, 90Hz, and 120Hz on smartphone screens actually do? I've heard they increase battery consumption, but I've also noticed that things like gaming or scrolling feel smoother on my device. Is the difference really significant, or is it just marketing?
Why is refresh rate important on Android phones?

The truth is, the refresh rate topic is something that's becoming more noticeable in daily use, even though I came from a 60Hz phone. What surprised me the most when switching to a 90Hz+ panel was how smooth scrolling feels in apps like Reddit or Instagram, especially when you scroll quickly. Before, you'd notice those little "janks" with 60Hz animations, but now you don't even perceive them. In games like Genshin Impact or Call of Duty Mobile, the difference is massive: movements are more precise, and there's no annoying lag when turning the camera.
That said, the battery impact is real. I've noticed that with 120Hz enabled in the background, the phone gets a bit warmer and the battery drains 10-15% faster during normal use. My solution was to switch to adaptive mode (for example, on Pixels it adjusts automatically based on what you're doing) or set up a custom profile: 60Hz for reading, 90Hz for social media, and 120Hz only for gaming. That way, you don’t sacrifice battery life without giving up smoothness when you really need it.
60Hz displays may be the old standard, but they feel perfectly fine for everyday scrolling or short usage sessions. When I was using the Redmi Note 8 Pro, I didn’t have any issues with 60Hz—everything looked smooth. But after switching to the Redmi Note 10 Pro and getting used to 90Hz, the biggest difference I noticed was how the scrolling motions no longer felt stuttery or choppy. Switching between apps or playing games, the slight "tir-tir" lag I experienced on 60Hz was completely gone at 90Hz.
As for battery life, it’s a bit of a mixed bag, but I find it reasonable. In normal use, 90Hz does consume about 10-15% more power, but the performance boost I get in games and apps makes up for that extra drain. I did try forcing the device into 60Hz by turning it off, but I ended up switching back to 90Hz because the difference in smoothness was too noticeable. At the end of the day, preferences vary from person to person.
Judging by your usage, 60Hz is plenty for daily Weibo scrolling and video watching. For gaming or high-frame-rate animations, I’d cap it at 120Hz—saves battery and feels smoother. The auto-adjust is fine, but running 120Hz manually all day will just drain your battery.
The truth is that screen refresh rate is a topic that sparks a lot of debate, but in my case, after upgrading from 60Hz to 90Hz on my previous phone, there was no going back. Sure, in everyday tasks like browsing or scrolling through social media, you don’t notice much of a difference, but when you’re gaming or just scrolling quickly, the smoothness is a whole other level. Transitions look much smoother, and even the touch response of the panel feels more responsive.
That said, battery life is the weak point. With 90Hz or 120Hz running constantly, you can definitely feel the extra drain, but most modern phones have adaptive modes that help balance it out. I’d only turn on 120Hz for gaming and drop it to 60Hz in power-saving mode so the battery wouldn’t drain too fast. In the end, if you’re not gaming or using apps that really take advantage of higher refresh rates, it’s not really worth it—but for those who do, it’s a game-changer.
