For a certain kind of enthusiast—someone who prizes control, longevity, and a stripped-down software experience—installing LineageOS on the Zenfone 9 is an appealing proposition. But is it the right move for most users? This editorial walks through the rewards, the trade-offs, and the practical realities. close to stock

There are a few things you lose or must handle differently compared to the stock ASUS firmware:

Lineage's built-in "Battery Saver" does not automatically drop to 60Hz. Install Resolution Changer or AutoHz to set custom profiles: 60Hz below 20% battery, 120Hz above.
