- IPhone 17 air should only be 5.5 mm thick
- A weight of 143 grams was also rumors
- The battery capacity should be 2,800 mAh
It is the year of the ultra-thin phone, and after the great unveiling of the Samsung Galaxy S25 Edge earlier this week, we now have some specifications for iPhone 17 air that Apple should unveil in September.
According to the famous Tipster Yeuux1122 (via @jukanlosreve), the iPhone 17 air will only be 5.5 mm back and back – which beats the thickness of 5.8 mm from the Galaxy S25 edge by a narrow margin.
The other details revealed here are that it will come with a 2,800 mAh battery (compared to 3,900 mAh for the Galaxy S25 edge) and weighs around 145 grams (compared to 163 grams for the Samsung model).
Since the iPhone 16 is delivered with a 3,561 mAh battery wrapped inside, which raises a few questions on the air duration of the iPhone 17 between the loads – and if you can spend the day without plug it in.
Battery capacities and cases

Hopefully Apple engineers will be able to find a way to get as much juice as possible from this smaller battery and this super thin frame. Mark Gurman de Bloomberg, who is generally reliable with regard to Apple rumors, says that the lifespan of the iPhone 17 air battery will be tied with current iPhones.
We also heard that Apple would introduce new high density battery technology with this model, which means more battery life unless there is a capacity. Apparently, the same technology is also defined for the next foldable iPhone.
It should also be noted: a source indicates that Apple will bring back its official case on the battery of the iPhone this year, in order to compensate for battery defects with the air of the iPhone 17. You may want to take this into your budget if you plan to take one.
Although nothing has been confirmed yet, the iPhone 17 air should largely replace the iPhone 16 Plus in the current range. There have also been a lot of discussions on a significant overhaul for iPhone 17 pro and iPhone 17 pro Max models, so there are a lot to hope in September.
