Many Android devices today offer the ability to estimate how long it will take to fully charge the battery while plugged in. These devices typically support high-wattage fast charging, and the time required to reach a full charge can vary depending on the specific charging protocol in use. Providing such time estimates helps users better understand and evaluate their device’s charging behavior.
With iOS 26, Apple has introduced a similar feature. Since the charging power differs between wired and wireless methods, the time needed to fully charge the battery also varies. Accordingly, when charging, the iPhone will now estimate the remaining time required to reach a full charge.
This estimated duration can help users gauge the speed of their chargers. For instance, Apple’s classic 5V1A charger or a Qi wireless charger limited to 5W will charge at a significantly slower rate, thus requiring much more time to complete a full charge.

Users can find the remaining time estimate within the Battery section of the Settings app in iOS 26. However, Apple has yet to introduce a widget for this feature. Without a dedicated widget, accessing this information requires navigating into Settings each time, which is less convenient.
Given that iOS 26 is currently in the developer preview phase, it is likely that Apple will refine this feature in future updates—perhaps by displaying the estimated time remaining on the Lock Screen or by offering a dedicated widget, allowing users to view the information at a glance.
Interestingly, Apple once provided a similar battery time estimate feature on Mac devices, but it was removed many years ago. Now that this functionality is appearing on iPhone, it remains to be seen whether macOS will one day reintroduce it as well.
