See Battery Charge Time Estimates

Charging is way less mysterious now. When you plug in your iPhone on iOS 26, you’ll see an estimate of how long it will take until it’s fully charged.

Yes, this feature has existed for years on other devices, but better late than never. As soon as you install iOS 26, the time remaining will be displayed by default. All you need to do is start charging your iPhone and then tap the Lock Screen to turn it on. The remaining time will appear above the clock.
