iPhone 18 Pro/Max: 10 Essential Answers You Need Before Upgrading
Tom’s Guide’s Mark Spoonauer breaks down the iPhone 18 Pro and Pro Max in 10 key questions. The Pro Max is heavier (249 g / 8.78 oz) than the Pro (211 g) largely due to a bigger vapor‑chamber cooling system, blades for a wider variable aperture, and a larger internal battery. The Max also carries a larger battery—about 5,567 mAh on the eSIM version versus 5,088 mAh on the 17 Pro Max—aiming for better endurance, while Apple keeps the phones’ overall external dimensions similar to last year so many 17 Pro accessories still fit. The piece casts the upgrade in terms of an A20 Pro performance leap, battery life, and whether you should opt for the Pro or Pro Max, or wait for rumors of an iPhone Duo. It also notes case compatibility across generations (17 Pro cases fit 18 Pro/Max) and compiles reader questions from Tom’s Guide YouTube, TikTok, and an Apple leadership interview.
