iPhone 15 Pro Max review: Apple makes a strong case for its biggest phone

“Let’s charge the iPhone 15 Pro Max before going to bed,” I thought wearily after a long day at Apple Park. Even though the device, which I had just unboxed a few hours earlier, was still showing at least 80 percent left of juice, I wanted to make sure it didn’t run out the next day. Time with a new review unit is precious, and I couldn’t risk wasting any of it on a dead phone.
