The new iOS 17 software from Apple has a fair number of cool features that will make your life easier, from the ability to leave FaceTime video messages for friends and family to StandBy mode, which turns your iPhone into a digital clock and smart display when you set it down in landscape mode. I also like NameDrop, which makes it easy to share your contact info with others via AirDrop and the (allegedly) more accurate autocorrect for the iPhone's keyboard.
But my favorite iOS 17 feature by far is Live Voicemail, which could save you a ton of time. It's one of those a-ha moments I experienced during WWDC 2023 and a feature I can see myself using all the time.
