• More accurate time to 80% and 100%, based on how your charger actually slows down • Rank chargers and cables within the same battery range (20–80% by default) for a fairer comparison • The charging curve now shows the fast, tapering and trickle phases, with an explanation • Bedside mode shows time to 80% first and dims the screen to save power • Plugging in while locked no longer makes the shortcut fail (iOS 26 or later) • Fixed the estimated battery level lagging behind after returning to the app • Tidier charger lists, and a new "Rate us" row in Settings

About accuracy iOS only gives apps the battery level in 5% steps, so the watts shown on iPhone are estimated from how fast the level rises and your battery's capacity. They may differ from the true power and are not a lab measurement. Privacy No account, no ads, no tracking. Your records stay on your iPhone.
