    Save a result, switch the charger or cable, then save again to compare.

    For a fair comparison

    Compare chargers at similar battery levels, ideally below 80%, because charging slows down near full. Keep the screen brightness and the open apps the same, and don’t use the device much while it measures.

    Fast charging works only when the device, the charger and the cable all support the same standard, like USB Power Delivery.
