Apple iPhone 12 Pro Max vs Apple iPhone 18 Pro

Our Verdict: The iPhone 12 Pro Max and the iPhone 18 Pro are six years apart, which is enough for a real difference. The 18 Pro has the better camera on paper, 48MP versus 12MP, plus a 18MP selfie camera against 12MP, and the 18 Pro goes up to 2TB of storage, where the 12 Pro Max tops out at 512GB. The 12 Pro Max has the bigger screen, 6.7" against 6.3", and the 18 Pro is the lighter phone at 211g against 228g. The 18 Pro is the better phone; upgrade from the 12 Pro Max if you want the newer hardware, or hold on if yours still does the job.

Buying outright, the 12 Pro Max starts at £231 SIM-free.
