If the battery on the first iPhone Air let you down, a new rumor says Apple is working on it. The iPhone Air 2 may be even thinner than the original and still hold more charge. Apple hasn’t confirmed any of it.
The claim comes from a blog post on Naver by yeux1122. The tipster claims the phone would be about 0.4mm thinner than today’s model. Apple lists the first iPhone Air at 5.6mm, so the sequel would land near 5.2mm, or roughly 7% thinner.
Why the battery matters more than the thickness
Why does this matter? Because thin phones have a habit of running out of juice early. Samsung’s Galaxy S25 Edge, another ultra-thin phone, had battery life problems of its own, with light use leaving about 10% to 15% charge by evening. The first iPhone Air lasted about 6 hours and 41 minutes in PhoneArena’s battery test, a little under the average for its class.
The new rumor says Apple wants to change that. The upcoming phone would use a battery that packs more power into the same space. That would let capacity go up even as the body gets slimmer. However, we don’t know how Apple plans to achieve that since the company hasn’t shown any public interest in silicon carbon battery tech.
Tipster Digital Chat Station claimed in July that the battery would be 3,500mAh, up from 3,149mAh today. That’s about 11% more. A bigger battery doesn’t guarantee longer life, either. That being said, a more efficient new chip should help too, since it would drain less power.
What we still don’t know
Apple hasn’t said a word about the iPhone Air 2, and no report names a price. According to the rumors, the handset is expected to arrive early next year, alongside the standard iPhone 18 and the iPhone 18e. So, if the first iPhone Air’s battery kept you from buying one, there’s nothing to decide yet. Keep an eye out for anything Apple says about it next year.
