Recent leaks hint at significant battery upgrades for the upcoming iPhone 18 Pro models, with the Pro Max variant potentially housing the largest battery ever seen in an Apple device. This enhancement is crucial to meet the higher power requirements driven by new AI functionalities. Additionally, the Pro Max is set to launch with a physical SIM version in India, with official specifications expected to be revealed later this year.

Apple is increasing the battery capacity of the iPhone 18 Pro and iPhone 18 Pro Max, but users should not expect more endurance. Instead, it could benefit Siri AI.

Apple sometimes gives iPhone Pro Max models a special advantage over Pro, and a new leak indicates that might happen with the iPhone 18 line.
