The announcement of the iPhone Air surprised exactly nobody during today's Apple "Awe dropping" event. As we finally get officiall details about this lightweight smartphone model, one of the biggest questions is about the battery. Thin devices mean thinner batteries, so we've been curious to see how the iPhone Air will stack up. One thing we now know is that it's less beefy than standard smartphones when it comes to wireless charging. According to the tech specs provided by Apple on its website, the iPhone Air charges at 20W on both MagSafe and Qi2 wireless charging, whereas the other iPhones announced today charge a little faster at 25W. Apple also shared fast-charging capabilities for the iPhone Air: "Up to 50 percent charge in 30 minutes with 20W adapter or higher (available separately) paired with USB‑C charging cable, or 30W adapter or higher paired with MagSafe Charger (both available separately)." The spec sheet also says that the iPhone Air on its own offers up to 27 hours of video playback or up to 22 hours of streaming video. When coupled with a dedicated iPhone Air MagSafe battery pack, those figures jump to up to 40 hours and up to 35 hours, respectively. The Apple "Awe dropping" event has concluded after the company announced new iPhones, Apple Watch and AirPods models, as expected. The full rundown of new releases: the iPhone 17, iPhone Air and iPhone 17 Pro and Pro Max; the AirPods Pro 3 (with live translation and a heart rate sensor); and the Apple Watch SE 3, Apple Watch Series 11 and Apple Watch Ultra 3. The company also confirmed that all of its new operating system upgrades including iOS 26 will be available as free upgrades on September 15.
