iPhone battery settings get a nice update in iOS 26, including a new intelligent battery saver mode called Adaptive Power. The iPhone will also now track extra battery stats, like your average power consumption throughout the day.
But perhaps the most notable enhancement is that the iPhone can now tell you exactly how long it will take for your battery to charge. Right at the top of your lock screen, when plugged in to power, your phone will now show the estimated time to charge until it hits 80%.
