Know When Your iPhone Reaches a Certain Charging Percentage

Granted, this feature isn’t available in the beta version of iOS 18.2, but inside the code of this beta is a feature that can show you how long will it take your iPhone to reach a certain battery percentage when you’re charging it. 

For instance, you’ll be able to see how long it would take for your iPhone to reach 50% or more if you need to. Again, this feature isn’t available in the beta just yet, so we might see it at a later date.
