Macworld says the iPhone 18 Pro Max may come with a 5,425 mAh battery in the eSIM-only version and a 5,235 mAh battery in the physical SIM version. For comparison, the iPhone 17 Pro Max has a 5,088 mAh battery in the eSIM-only model and a 4,823 mAh battery in the physical SIM model.
iPhone 18 Pro Max battery leak
If these figures are accurate, the eSIM-only iPhone 18 Pro Max will get a 337 mAh increase over the iPhone 17 Pro Max, while the physical SIM model will get a 412 mAh increase. That sounds like a solid jump, especially because the iPhone 17 Pro Max already offers strong battery life.
The difference between the two models likely comes from the extra internal space Apple gets when it removes the physical SIM tray. Apple already sells eSIM-only iPhones in some markets, while other regions still get models with a Nano SIM slot.
Here is the leaked comparison:
iPhone 17 Pro Max eSIM: 5,088 mAh
iPhone 18 Pro Max eSIM: 5,425 mAh
iPhone 17 Pro Max Nano SIM: 4,823 mAh
iPhone 18 Pro Max Nano SIM: 5,235 mAh
Should you trust this leak?
This report needs caution because the source trail is not very clear, and the original social media post appears hard to verify. Macworld also notes that the leak came from accounts without a strong public track record.
At the same time, earlier rumors have also suggested larger batteries for the iPhone 18 Pro Max, so the new numbers do not look completely random. Apple is also expected to use the A20 Pro chip, which should improve power efficiency and help the phone last longer between charges.
If the leak proves accurate, the iPhone 18 Pro Max will offer one of the biggest batteries ever used in an iPhone, giving Apple another strong reason to position it as a serious upgrade for users who care about battery life.
