Leaked images from China show the iPhone 18 Pro Max battery with a capacity of 5,391 mAh for the physical SIM version, matching earlier rumours. The eSIM-only model is expected to have 5,567 mAh. The iPhone 18 Pro is said to get 4,288 mAh (eSIM) and 4,056 mAh (physical SIM), only a 1-2% increase over the iPhone 17 Pro, reports GSMarena. Meanwhile, TrendForce estimates the iPhone 18 Pro's bill of materials has risen 38% for the 256GB model, with memory costs now 34% of BOM. Separately, a tipster claims Apple will hike prices by $100 (roughly Rs 10,000) across all iPhone models, including older ones, at the September 8 launch, according to Gadgets360.
