iOS 27 beta 4 arrived today, and per Macworld<\/a> it includes code references to what\u2019s likely a new iPhone Ultra feature: dual batteries.<\/p>\n Macworld found code references in iOS 27 beta 4 to iPhone with multiple batteries<\/p>\n Earlier this month, Weibo leaker Digital Chat Station revealed<\/a> that Apple\u2019s forthcoming iPhone Ultra<\/a> is likely to include not one, but two separate internal batteries.<\/p>\n This isn\u2019t uncommon for foldable smartphones, but it would be a first for the iPhone.<\/p>\n And today, following the release of iOS 27 beta 4, we have strong evidence corroborating the leaker\u2019s claim.<\/p>\n Filipe Esp\u00f3sito reports at Macworld<\/a> that the new beta includes code strings referencing a multi-battery iPhone model. He writes:<\/p>\n The new code strings explicitly state that they are intended for a multi-battery iPhone, alongside the existing references to single-battery iPhones (emphasis ours): \u201cThe\u00a0batteries\u00a0in this iPhone are performing as expected,\u201d reads one of the strings. Another mentions that \u201cthe health of the\u00a0batteries\u00a0in this iPhone has significantly degraded.\u201d<\/p>\n We\u2019ve seen plenty of other<\/a> iOS 27 code references to the iPhone Ultra in the past. There have been code leaks revealing that a foldable iPhone is coming, and one with multiple displays.<\/p>\n Now, add to those today\u2019s new code that mentions an iPhone with multiple batteries.<\/p>\n Per a regulatory filing<\/a>, the two batteries will have capacities of 1,921mAh and 2,962mAh respectively, for a total of 4,883mAh.<\/p>\n All of this supports what has previously been reported about the iPhone Ultra, which is expected to be unveiled in early September<\/a>.<\/p>\n Best iPhone accessories<\/p>\n
