Tim Cook from Apple is raving about the battery on the new iPhone Air, calling it really solid. This thing’s the skinniest iPhone they’ve ever put out, coming in at just 5.64 millimeters thick. And get this, the official word is you can squeeze up to 27 hours out of it for stuff like watching videos.
Apple dropped the iPhone Air earlier this week, right along with three other fresh models. Tim Cook chatted with Jim Cramer on CNBC about it, tackling those worries folks have—does making it so slim mean the battery takes a hit? Nah, he says. “The battery life’s great,” Cook told him. “You’re gonna love it.” They basically rebuilt the phone from the guts up to stretch out that charge as much as possible.
He dove into the details too, explaining how ditching the old physical SIM slot for eSIM freed up room inside. That extra space? Straight to beefing up the battery. Pretty smart, right? Earlier in the talk, Cook got all excited, saying it’s like “you’re holding the future in your hand.” Makes you wonder if we’ll see a bunch more Air versions down the line, maybe even one with that wild all-glass, curved design.

Anyway, Apple’s shaken things up with how they laid out the insides of the iPhone Air. Most of the main parts are crammed up top in the case, leaving the bottom wide open for a bigger battery. According to their stats, yeah, 27 hours of video time on a single charge. Stack that against the regular iPhone 17’s 30 hours, the Pro’s 33, or the beefy Pro Max hitting 39. Not too shabby for something so thin.
Oh, and they’re rolling out a special MagSafe battery pack just for the Air—kinda hints that you might want a top-up now and then if you’re using it hard all day. We haven’t gotten to run our own tests on the battery yet, but I did mess around with the phone a bit hands-on. Once it starts shipping out next Friday, we’ll hear real stories from people using it, and that’ll paint a clearer picture of how it holds up.
