Apple's iOS update added these features to your iPhone.

While you get ready for Apple to release iOS 17.5, don't overlook the features Apple added to the iPhone with iOS 17.1. The company released the update to the public in October, more than a month after the arrival of iOS 17. The update addressed a few bugs and brought some features to the iPhone, like upgrades to Apple Music.

Here are the features and fixes iOS 17.1 brought to the iPhone.

iPhone 12 radio frequency concerns addressed

France's National Frequency Agency said on Sept. 12 that the iPhone 12 exceeds European-specific absorption rate limits, and it appears Apple addressed those concerns with iOS 17.1.

"iOS 17.1 includes an update for iPhone 12 for users in France to accommodate this specific test protocol that requires reduced power when off-body on a static surface," Apple posted Oct. 10. "iPhone 12 will no longer increase the allowed power when the off-body state is detected, such as while it is sitting on a table."

New StandBy mode settings

StandBy mode is one of my favorite new iOS features, and with iOS 17.1, Apple gives StandBy mode more setting options. With iOS 17.1, you have the option to turn StandBy mode off after 20 seconds, never or "Automatically." Apple writes that if you choose Automatically, the display will turn off when your iPhone is not in use and the room is dark, like when you're sleeping at night.

However, I checked these settings on my iPhone 14 Pro and iPhone XR and only found these options on my iPhone 14 Pro. So it appears the new settings are only available on iPhones with an always-on display.

Apple Music upgrades

Apple Music makes it easy to find your Favorited content.

With iOS 17.1, Apple added a new button in Apple Music that allows you to quickly find Favorite songs. When a song is playing and you're looking at its card on your iPhone, there's a star outline near the song's title. You can tap this star to add the song to your Favorites.

There's also a new way to find all your Favorited playlists, albums and songs. To find them, go into the corresponding category in Apple Music, tap the button in the top-right corner of your screen, and tap Favorited.

Apple Music also shows you song suggestions with iOS 17.1. To see them, go into any of your playlists and scroll to the bottom of the playlist to see a section called Song Suggestions. These are songs that the app thinks you might like, based on your musical tastes.

AirDrop using cellular data

With iOS 17, Apple upgraded AirDrop with NameDrop, which allows two devices to tap each other and exchange contact information -- kind of like exchanging digital business cards. And in iOS 17.1, Apple lets you use cellular data to send and receive information over AirDrop when two iPhones are out of range of each other.

Flashlight symbol in Live Activities 

Have you ever accidentally switched on your iPhone's flashlight and had someone point it out to you later? Some iPhone users won't have to worry about that anymore. With iOS 17.1, when you turn on your flashlight, a little flashlight symbol appears in the Live Activities feed across the top of your screen. However, I couldn't replicate this symbol on my iPhone XR, so this feature likely only works on Live Activity-enabled iPhones, like the iPhone 14 Pro and Pro Max, as well as the iPhone 15 lineup.
