The Super Retina XDR displays on the iPhone 13 Pro models are super bright. They can deliver 1,000 nits of max brightness outdoors compared to 800 nits on the iPhone 12 Pros (and the new iPhone 13 and 13 mini).
We’re all for a better and brighter screen, but that impressive display can also be a battery killer if you’re using your phone on max brightness all the time. If you’re already doing all you can to make your iPhone battery last longer but are still running low on juice, grayscaling your phone to get rid of bold colors might be a big difference-maker when your battery hits single digits.
