Battery Problems Threaten iPhone Slim and Fold

A new rumor claims that both Apple and Samsung are having difficulty making thinner batteries, which could limit how thin future phones like the expected iPhone 17 Slim can be. The source of this rumor, yeux1122, has a mixed track record. According to their blog post in translation, '[The] supply of new internal substrates will not be possible next year.' If correct, it is thought that the battery difficulty would mean an iPhone 17 Slim could be no thinner than 6mm.
