How does the battery in the iPhone X compare to that of its predecessors? Is it better? Worse? The same? Is investing in a new phone really worth it if you’re only considering battery life? Well, we ran a quick test to find out.Apple’s website claims the battery in the iPhone X can last up to two hours longer than that in the iPhone 7. And although the iPhone 7 wasn’t actually one of the phones we tested, that kind of power could theoretically allow for up to 12 hours of continuous internet use or 60 hours of wireless audio playback. But did it stack up?Taking into consideration equal usage, we made sure all four of the phones we were testing — i.e., the iPhone X, 8 Plus, 7 Plus, and 6S Plus — were connected to the same Wi-Fi network and had their screens set to 50-percent brightness. We also ensured each was utilizing the same account, so they would receive notifications at the same time. Once set up, we streamed a 10-hour Nyan cat video and waited to see which order the phones died in.
