Forget Apple Intelligence — iOS 18.2 beta could be introducing 'Battery Intelligence'
A code-diver at 9to5Mac found a "BatteryIntelligence" framework that could be used to estimate a charge time for your iPhone. Users are apparently able to request a notification with a prediction of how long it'll take the phone to fill up, except this feature is not active within iOS 18.2, and looks to be incomplete.
