Refresh rate explained: What does 60Hz, 90Hz, or 120Hz mean?

Image
High-end smartphones increasingly boast blazing-fast 90Hz and even 120Hz refresh rate displays. This sounds great on paper. It’s yet another way that smartphones attempt to differentiate themselves from one another. But should you buy a phone because of this latest display tech trend? It honestly depends. The benefits of high refresh rate phones and even how they work is rarely well understood. While games and content can look a lot smoother, whether it’s worth the extra battery consumption depends a lot on the user and the handset.

This can be an irritating reality of the modern smartphone world, particularly when handsets are increasingly packing in larger and larger battery capacities. Fast charging and all-day battery life certainly seem doable, yet relatively few smartphones offer these capabilities and slow wired charging is still a problem with many modern devices.
