Compare Mobile Phones Side-by-Side

These two phones are so close that the decision really hinges on network support more than day-to-day hardware. Both give you the same large 6.75-inch 120Hz display, the same 4GB RAM, and the same hefty 6500mAh battery, so scrolling, media use, and endurance should feel broadly similar.

The Oppo A6t 5G is the safer buy if you want a phone that will age better on newer mobile networks. That 5G support is the one practical advantage here, especially if you keep your phone for several years or live somewhere with decent 5G coverage.

The Oppo A6x 4G only makes more sense if it is noticeably cheaper or if 5G simply does not matter to you. Otherwise, with so many core specs matched, it is hard to ignore the A6t 5G’s extra connectivity headroom.
