There are many battery-powered devices that can give you an estimate of how long they will need to stay plugged in until they are fully charged. This isn’t exactly a new feature. MacBooks give you this information in the Battery menu in Settings or in the menu bar, for example.
With all the battery management and analysis built into our modern iPhones, it’s pretty remarkable that they don’t do this. Luckily, a “cooldown” feature could be on the way.
9to5Mac discovered code in the latest iOS 18.2 beta that points to a new BatteryIntelligence frame. The framework will take into account how much charge your battery can hold, its state of charge, and how much power it receives from the charger (USB-C or wireless, we assume) and produce an estimate of how long it will last for which she will do. take for the battery to charge.
According to 9to5Mac, for example, users will be able to receive a notification indicating how long it will take to load up to the current limit (80% or whatever value you set). I could see Apple embedding the information in Dynamic Island, or perhaps on the lock screen.
The feature isn’t enabled yet, so it’s unclear if it will be available in iOS 18.2 or later. This may also be limited to specific iPhone models, just like custom charging limits or other battery features.
