That Apple often coughs and limits some features in Europe and other markets, it got so far last year that it offers in the US and other selected markets iPhone 17 Pro a iPhone 17 Pro Max with two hours longer battery life than in Europe and other markets. If you bought your phone anywhere other than the US, Canada, Japan, Mexico, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates or the Virgin Islands, your phone has a physical SIM card slot and therefore your battery capacity is 3988 mAh. If you bought your phone in the above markets, your battery capacity is 4252 mAh and as Apple Officially claims two hours longer battery life.
ProThe problem is that people don't have the option to choose whether or not they want a phone with a physical SIM card slot, and those phones that do have a physical SIM card slot have shorter battery life. On the website change.org There was even a petition asking for Appel made eSIM-only models available in Europe as well, ensuring that all users had a consistent experience with the same product. If you are also concerned about this issue, you can sign the online petition directly at the link above.
