There are a few things to consider when answering this question. For one, the iPhone's battery is designed to last a full day on a single charge, so even if Raise to Wake does use more power than other features, it's not likely to have a significant impact on battery life. Additionally, Apple has implemented power-saving technologies in iOS that minimize the amount of power used by the display and sensors while still providing an optimal user experience.
With that said, it's difficult to say definitively whether or not Raise to Wake uses more battery power than other iPhone features. However, based on our understanding of how the feature works and Apple's commitment to power efficiency, we believe that its impact on battery life is minimal.
