Leaked iPhone 18 Pro Max battery specifications show 5,235 mAh for Nano SIM models and 5,425 mAh for eSIM-only variants, according to Macworld.
That’s an increase of 8.5% and 6.6%, respectively, compared to the 4,823 mAh/5,088 mAh capacities of the iPhone 17 Pro Max models. These rumored capacities represent significant 6.6-8.5% increases over the iPhone 17 Pro Max and would exceed Samsung Galaxy S26 Ultra’s expected 5,000 mAh battery, the article notes.
The iPhone 18 Pro and iPhone 18 Pro Max are expected to arrive in the September/October time frame. The foldable iPhone — expected to be dubbed either the “iPhone Fold” or “iPhone Ultra” — should arrive shortly thereafter.
The standard (non-Pro) iPhone 18 should debut early next. An iPhone 18e and second generation iPhone Air are also anticipated in the first half of 2027.
