A leak from the Chinese web informs us about the capacity of the battery supposedly integrated into the future iPhone 17 Pro Max. If this information is confirmed, the device would simply have the largest battery ever integrated into an iPhone.
5,000 mAh. It would be the approximate capacity of the battery of the future iPhone 17 Pro Max, at least if we believe a leak from the Chinese social network Weibo. Expected next September alongside the iPhone 17, 17 air and 17 pro, the new Fleury of Apple would be equipped with the largest battery ever installed on board an iPhone.
As a reminder, the current iPhone 16 Pro Max is satisfied with a capacity of 4,685 mAh, against 4,441 mAh for the old iPhone 15 Pro Max. The iPhone 17 Pro Max would therefore have a significantly enhanced capacity.
Towards an XXL autonomy for the iPhone 17 Pro Max?
That said, Apple would simply stick to a battery similar to what its main competitor has been offering for several years. At Samsung, the imposing Galaxy S25 Ultra is indeed equipped with a 5,000 mAh battery, and this capacity was already used by the brand on the Ultra and S24 Ultra S23. Apple would therefore catch up with its “delay” in this area. Neither more nor less.
With this potential battery of 5,000 mAh The iPhone 17 Pro Max could therefore be maintained in the race for autonomy in front of its rivals. A good part of the question will not be limited to this only case of battery capacity. As you know, autonomy is also greatly played on the software optimization and the energy efficiency of the SOC and the 5G modem.
In this case, the iPhone 17 Pro Max will take advantage of both iOS 26 and an Apple A19 PRO processor (which should exploit the new Nude 3 Nmc evolution of TSMC). However, the device would once again be equipped with a Qualcomm 5G modem, not with an Apple C1 modem whose energy efficiency had been appreciated on the iPhone 16th.
