There is a very good reason why you should hold off buying the iPhone 17 Air for a couple of years
The iPhone 17 Air could be as thin as 5.5mm which would make it the thinnest iPhone ever shipped taking the title from the iPhone 6 (6.9mm). It would even be thinner than last year’s M4-powered iPad Air. Both the 11-inch and 13-inch variants weigh in at 6.1mm thin. The iPhone 17 Air will also challenge the 11-inch M4-powered iPad Pro which is 5.3mm thin.

As we’ve pointed out, the thin body used with the iPhone Air will require Apple to try anything to give the device a decent battery life. After all, what is the point of having a great-looking thin iPhone model in your hand if it needs to be plugged in during the day? To reiterate, the first time we might see the new tech on the iPhone screen will be 2027. So you could wait until this year’s third quarter to see if any word leaks about Apple’s intention to add the new low-temperature polycrystalline oxide (LTPO) thin-film transistor (TFT) to the iPhone 19 line.
If Apple does decide to use the new LTPO technology for its 2027 models, you might want to hold off on purchasing the new iPhone Air model until 2027. Not only should you experience longer battery life with the iPhone 19 Air, but you’ll also have a couple of years to determine whether the ultra-thin iPhone is something you really want and need.
