The iPhone 7 has slightly better battery life, but you’ll still want to keep plenty of charging cables around.

Anker’s kevlar-wrapped PowerLine cords are our readers’ favorite brand of Lightning cable, and you can get three for $20 right now. This three-pack typically costs $24, and buying three of them separately would usually cost $27. Not bad considering Apple’s charges $19 for just one of its inferior cables.
