iOS 26 introduces a new feature that allows users to know the estimated time it takes for their battery to charge when plugged in or on a wireless charger. This allows users to optimize their charging practices and determine the speed of a charger. The estimated time remaining until a full charge can be found in the Battery section of the Settings app. Apple has not yet added a new widget for this feature, but it could be added in the future. The iPhone battery charging estimates are available to developers in iOS 26, with the update expected to be released to everyone this fall.
