This time around, the P series is gently curved at the edges, with a glass design that softens the sides of both the P20 and the bigger P20 Pro. Both phones are thin, too: The P20 is 7.65mm thick (with a 3,400mAh battery) while the P20 Pro measures up at 7.8mm, with a larger 4,000mAh battery -- that's a massive battery for a phone this size, outclassing even the Galaxy S9 Plus. If it helps you to visualize those millimeters, both bookend a 7.7mm-thick iPhone X.

Beside the curves, the P20 also introduces a new color-gradient finish that Huawei's calling Twilight: a blend of dark blue, purple, turquoise and... was that a shimmer of crimson? One colleague commented that it was a lot like the "pearlescent paint" finish you might see on a high-end sports car. It's pretty hypnotic, but while journalists seemed to coo over it, it's a little too showy for me. People buy shiny, glitzy phone cases, not phones. Still, it's different.
