Mark Spoonauer, Tom’s Guide:

We run every phone we review through the Tom’s Guide battery test, which involves continuous web surfing over 5G cellular at 150 nits of screen brightness. And these are the results compared to the iPhone 12 series.

Follow the headline link for the details and a longer list, but here are the iPhone 13 vs iPhone 12 series numbers (hours:minutes):

• iPhone 13 Pro Max … (12:16)
• iPhone 12 Pro Max … (10:53)
• iPhone 13 Pro … (11:42)
• iPhone 12 Pro … (9:06)
• iPhone 13 … (10:33)
• iPhone 12 … (8:25)
• iPhone 13 mini … (8:41)
• iPhone 12 mini … (7:28)

Guessing you won’t drive your iPhone’s as hard as the Tom’s Guide folks did, so your battery life might be even better.
