Apple iPhone 12 Pro vs Apple iPhone 15

The 15 5G leads on camera hardware with a 48MP main sensor to the 12 Pro's 12MP, and the 15 5G packs the bigger battery, 3349mAh against 2815mAh, which usually means longer between charges. The 15 5G is the lighter phone at 171g against 189g. Coming from the 12 Pro, the 15 5G is a genuine upgrade rather than a token one.
