There are rumors of an updated iPhone model, possibly called the iPhone Air 2, which may feature a bigger battery and updated design, including a second camera. Some reports suggest the battery upgrade could be significant, with one outlet mentioning a possible 30 hours of use, although the exact details are unclear. The rumors also seem to be conflicting with reports of an iPhone 18 Pro Max, which may or may not be the same device, with some outlets suggesting it could have a larger battery but also increased weight and thickness.
