As for dimensions, compared to the iPhone 13 Pro Max, the iPhone 16 Pro Max is slightly taller (163mm vs. 160.8 mm) and thicker (8.3mm vs 7.7mm), but Apple's shaved down the weight significantly (to 227g from 240g).

It's not surprising that the largest smartphones by the likes of Apple and Samsung have the longest battery lives, because they have the biggest batteries — but new testing shows that the iPhone 16 Pro Max beats them all.

The 13 Pro Max still feels fast, takes excellent photos, and easily lasts all day on a full charge even at 88% battery health. The usual improvements you expect from a new iPhone—faster processor, better cameras, longer battery life—would be lost on me in day-to-day use.
