Apple iPhone 11 Pro Max vs Apple iPhone 15
Our Verdict: If you've got the iPhone 11 Pro Max, the iPhone 15 is four years of updates on from it. The 15 5G leads on camera hardware with a 48MP main sensor to the 11 Pro Max's 12MP, and only the 15 5G is a 5G phone; the 11 Pro Max maxes out at 4G. There's more battery in the 11 Pro Max, 3969mAh to 3349mAh, which usually means longer between charges, and the 11 Pro Max has the bigger screen, 6.5" against 6.1". Coming from the 11 Pro Max, the 15 5G is a genuine upgrade rather than a token one.
If you'd rather pay up front, the 11 Pro Max is the cheaper buy at £180 SIM-free.
