The iPhone 11 Pro Max is the heaviest iPhone ever. It weighs 7.97 ounces — that's half a pound.
That doesn't sound huge, but its the heaviest smartphone on the market today. For comparison, the iPhone 11 Pro weighs in at about an ounce lighter, at 6.63 ounces.
The iPhone 11 Pro Max doesn't add many features that the 11 Pro doesn't already have. Is it worth carrying around an entire half pound iPhone for the slight upgrade? You'll have to make that call, but I don't think so.
