Macworld reports alleged battery capacities for iPhone 18 Pro Max
Macworld cited social-media leaks suggesting the iPhone 18 Pro Max may have a battery of 5,425 mAh with eSIM and 5,235 mAh with a physical SIM, representing a modest increase over the iPhone 17 Pro Max.
Macworld published figures from unnamed social-media sources that claim the upcoming iPhone 18 Pro Max will be equipped with a 5,425 mAh battery in eSIM models and a 5,235 mAh battery in physical-SIM models. The reported capacities exceed the iPhone 17 Pro Max’s 5,088 mAh (eSIM) and 4,823 mAh (physical SIM) batteries.
The outlet noted that the numbers align with a recent data breach at Apple supplier Tata Electronics, which has supplied legitimate leak material in the past, though the exact origin of the battery figures remains unverified.
Analysts said any increase in capacity, combined with efficiency improvements from the forthcoming A20 Pro processor, could extend usage time compared with the current generation.
