Purported iPhone 17 Pro Max dummy
A new video of a dummy of the forthcoming iPhone 17 Pro Max has surfaced, backing up previous rumors that the model will be significantly thicker than the current model.
The news that the iPhone 17 Pro Max would have a thicker chassis than the current iPhone 16 Pro Max was first reported in March 2025. It was also reported that this model would get an advanced vapor chamber cooling system, which might account for the increased size.
That cooling feature is expected to be in both of the new Pro models, but as yet there hasn’t been news that the iPhone 17 Pro will also be thicker. The new video being circulated by leaker Majin Bu solely shows a dummy of the iPhone 17 Pro Max, but it does appear to confirm the extra thickness.
The 34-second video comes with no details, and solely features a hand rotating the device. Consequently, there are no measurements and little to specify that the model is thicker.
Visually, though, the phone in the video appears to fit with previous descriptions. Those have had the iPhone 17 Pro Max being 8.725mm (0.3435 inches), compared to its predecessor’s 8.25mm (0.3248 inches).
If the extra width is not to accommodate the cooling system, or some other as yet unknown feature, it may be to allow for a larger battery. AppleInsider has estimated that the 0.5mm increase could equate to as much as 8% more battery capacity.
Leaker Majin Bu has a mixed track record for accuracy. While he has been correct at times, he also erroneously claimed that the iPhone 15 would get two front-facing cameras.
Separately, it was reported in February 2025 that the iPhone 17 Pro models could feature reverse charging. This is when the iPhone itself is used to charge other devices, such as AirPods.
