Apple may launch the iPhone 18 Pro with different battery capacities depending on the market, according to a new leak. Physical SIM variants could feature a 4,056mAh battery, while eSIM-only models may get a larger 4,288mAh cell. The phone is also expected to feature Apple's 2nm A20 Pro chip and a variable-aperture 48-megapixel main camera. The upgrades could raise production costs, although Apple may absorb some of the increase instead of raising prices.
