You can even trust the Edge to make the decision for you, by enabling a setting that allows it to automatically adjust the display's refresh speed based on whether you'll benefit from the 90Hz refresh rate or whether it makes more sense to not tax the phone's battery. Scrolling through web pages is a pleasure, as you'll see when toggle back and forth between the 60Hz and 90Hz options.
The faster refresh rate is a welcome addition to the Motorola Edge. The standard OnePlus 8 also has a 90Hz refresh rate, as does the OnePlus Nord (though that latter phone isn't available in the US). While other phones offer even faster refresh rates - the Galaxy Note 20 Ultra and OnePlus 8 Pro both refresh at 120Hz rates - it's not often a feature you see in phones that cost less than $700. That marquee feature would be the Motorola Edge's 90Hz refresh rate, a speed it shares with the more expensive Edge Plus. That, plus a punch-hole cutout for the selfie cam, allows Motorola to present the Edge's screen without much in the way of bezels - and that's welcome, considering the marquee display feature that the Motorola Edge offers. The Motorola logo on the back of the Edge is just there for show - if you want to access the phone's fingerprint reader, it lives underneath the phone's display. Unlike phones that feature big, blocky camera arrays on the back these days, Motorola stacks its rear lenses in a sensible and subtle way.
