Apple’s next affordable iPhone could be getting a sizeable battery upgrade, with a new leak suggesting the iPhone 18e will share the same 4,430mAh battery capacity as the standard iPhone 18.
The claim comes from Weibo leaker Fixed Focus Digital, who has shared what appears to be an internal diagram comparing the two upcoming devices.
While the phones are expected to differ in areas such as their cameras and displays, the images suggest Apple could be using several of the same internal components, including their batteries.
The leaked diagrams identify the iPhone 18 under the codename “Taycan”, with battery capacities ranging from 3,671mAh to 4,430mAh. The iPhone 18e, reportedly codenamed “Nevera”, is listed with capacities between 4,005mAh and 4,430mAh.
Despite the different lower figures, both phones share the same maximum capacity, suggesting their largest battery configurations could be identical.
The variation may come down to Apple’s approach to physical SIM cards. In markets where iPhones still require a SIM tray, the additional hardware takes up space that could otherwise accommodate a larger battery.
Models sold in regions such as the US, where Apple has moved towards eSIM-only designs, can use that extra room for battery capacity.
If accurate, the leak would be particularly welcome news for buyers considering the cheaper iPhone 18e. Battery life is one area where a more affordable phone can offer a similar everyday experience to a pricier model, even if Apple reserves its better cameras and displays for the standard iPhone 18.
It also adds weight to earlier reports suggesting the two devices will have more in common than their names might suggest. Both are expected to use the same processor, while differences in camera hardware and display technology could help Apple maintain a clear distinction between the models.
However, there’s reason to treat the latest information cautiously. Fixed Focus Digital has a mixed record with Apple leaks, and the diagrams haven’t been independently verified.
A matching battery capacity also wouldn’t necessarily guarantee identical battery life, as display efficiency, processor behaviour and other hardware differences can affect how long each phone lasts.
Apple has yet to confirm either device or its battery specifications, so the 4,430mAh figure remains unconfirmed. Still, if the company does bring the same larger battery to both models, the iPhone 18e could become a more appealing option for buyers who care more about battery life than having the latest camera features.
