00:00Look, we knew there'd be a battery trade-off for a folding iPhone, but four hours?
00:04We ran the iPhone Duo alongside the iPhone 18 Pro Max in the Tom's Guide battery test.
00:09The Duo lasted 13 hours and 21 minutes.
00:12The Pro Max, 17 hours and 31 minutes.
00:16That's four hours and 10 minutes longer.
00:18Now, we tested the Duo unfolded with that big inner display in continuous use.
00:24Your everyday battery life will depend on how you use it.
00:27But here's what makes this interesting.
00:29The Duo CPU scores were within 1% of the Pro Max.
00:33So, you're getting practically Pro Max processing performance, but substantially less endurance in our benchmarks.
00:40Bigger picture, would you take the functionality of a folding screen or the extra four hours of battery life?
