iPhone 13 Pro Max is Apple's undisputed battery life champion

The iPhone 13 Pro range.

A comparative test putting all of Apple's currently available iPhones shows the new iPhone 13 range is significantly better, and the iPhone 13 Pro Max beats everything.

All reviews of the iPhone 13 range agree that battery life is much improved over 2020's iPhone 12 range, and that's chiefly down to a new design that enables a larger battery. Now, however, one YouTuber has put every iPhone, that Apple currently sells, through the same real-world test, and found the iPhone 13 Pro Max is extraordinarily long-lasting.

"The Pro Max lasted just under 10 hours," says economics student Arun Maini, whose YouTube channel is called Mrwhosetheboss. "This is not just the highest score I've ever recorded. It is miles ahead of anything else."

"It's not just a case that you won't have to worry about battery life here," says Maini. "It is more, they will actively impress you, in looking through Apple's past lineup, does not happen very often."

Maini took each of the seven iPhone models currently available from Apple, and ran them through the same tests.

Unsurprisingly, the iPhone SE was the weakest, with a battery life of just 3 hours, 38 minutes. The iPhone 11 was not a great deal better, at 4 hours, 20 minutes.

Most notably, aside from the iPhone 13 Pro Max's record-breaking result, was how the iPhone 13 mini's 6 hours, 26 minutes beat the iPhone 12 by 32 minutes.

Then in this one test, the iPhone 13 notched up 7 hours, 45 minutes. The iPhone 13 Pro reached 8 hours, 17 minutes, which Maini says puts it in the top 5% to 10% of all phones his channel has tested.

"I'm also just relieved," he said, "because last year the iPhone 12 actually outlasted the 12 Pro, which really just didn't sit right with me."

Finally, the iPhone 12 Pro Max lasted 9 hours, 52 minutes.
