The most striking design difference between these two phones is how the Moto X70 Air manages to be dramatically slimmer and lighter. At just 6 mm thick and 159 g, it undercuts the Edge 60 Pro's 8.2 mm profile and 186 g weight by a meaningful margin — a 27 g difference that is noticeable during extended one-handed use, and a 2.2 mm gap in thickness that translates to a genuinely more pocketable, svelte feel in hand. The volume difference reinforces this: the X70 Air displaces roughly 71.3 cm³ versus 96.3 cm³ for the Edge 60 Pro, a nearly 26% reduction in overall bulk despite similar footprint dimensions.
Both devices share an identical form factor philosophy — flat, non-folding slabs with no rugged reinforcement — so the comparison comes down to refinement. Footprint-wise they are nearly identical in width and height, meaning both will fit similarly in a pocket or case. The real divergence is in how much material each phone uses to fill that footprint. The X70 Air is clearly engineered around a thin-and-light brief, while the Edge 60 Pro accepts more girth, likely to accommodate other hardware choices.
On water resistance, both are rated Waterproof, but the X70 Air holds a slight edge with an IP69 certification versus the Edge 60 Pro's IP68. IP69 adds protection against high-pressure, high-temperature water jets — a more demanding standard than IP68's submersion test. For most users this distinction is academic, but it does signal tighter sealing on the X70 Air. Overall, the Moto X70 Air has a clear design advantage: it is thinner, lighter, more compact, and carries a higher ingress protection rating.
