iPhone 18 Pro's Secret: Why eSIM Users Get More Juice
Leaked specifications for the upcoming iPhone 18 Pro indicate a split in battery capacity between hardware variants. Models equipped with a traditional physical SIM tray are slated to carry a 4,056 mAh battery, whereas eSIM-exclusive models will reportedly boast a larger 4,288 mAh capacity. This architectural shift highlights how removing legacy components allows for greater internal volume optimization. As Apple prepares to expand its eSIM-only strategy to Europe, millions of international customers stand to gain improved battery longevity compared to previous generations.
