Apple iPhone 12 Pro vs Apple iPhone 15 Pro Max
Our Verdict: There's three years between the iPhone 12 Pro and the iPhone 15 Pro Max, so the iPhone 15 Pro Max is ahead on most things. The 15 Pro Max 5G has the better camera on paper, 48MP versus 12MP, and the 15 Pro Max 5G packs the bigger battery, 4422mAh against 2815mAh, which usually means longer between charges. The 15 Pro Max 5G goes up to 1TB of storage, where the 12 Pro tops out at 512GB, and the 15 Pro Max 5G has the bigger screen, 6.7" against 6.1". If you're on the 12 Pro, the 15 Pro Max 5G is a real step up, but only worth it if the changes above matter to you.
If you'd rather pay up front, the 12 Pro is the cheaper buy at £180 SIM-free.
