When Apple rolls out iOS 26 in just over a month’s time, it’s going to give your iPhone a pretty simple — yet really useful — new charging feature that you’ll use all the time.
Specifically, when you start charging your iPhone, it will tell you exactly how long it will take until it’s fully charged.
Charging time estimates

Apple has already released the public beta of iOS 26, providing us with our first experience of the upcoming features. One of these is the new charging estimate feature.
When you start charging an iPhone running iOS 26, either via a wired or wireless connection, the Lock Screen will display the current charge level and the estimated time to reach 80% charge. This way, you can leave your iPhone charging and come back exactly when it’s ready to go.
However, there’s one caveat: Once the iPhone’s charge gets 80% or higher, the charge estimate disappears from the Lock Screen.
