Messages: Rather than scrolling through one long message of multiple photos, iMessage now neatly organizes numerous images (sent simultaneously) into a stack you can swipe through.The Weather app has a fresh design, with more detailed graphics, a background that more precisely changes to current weather conditions, and access to high-resolution weather maps.

Weather: Apple bought the popular Dark Sky weather app in 2020, and it looks like we're finally seeing the fruit of that acquisition.

iCloud Backup: You can temporarily back up your data to iCloud, even if you don't have enough storage, to transfer your data to a new iPhone.

To enable Macro, you'll need to manually switch to the ultrawide camera and move close to a subject. To prevent this, you can toggle the Auto Macro feature off ( Settings > Camera > Auto Macro).

Auto Macro Toggle: In the iPhone 13 Pro models, the camera switches lenses when you get close to a subject to enable macro mode, but sometimes it keeps switching back and forth.

This format gives you greater control when editing, but the file sizes are much larger. Then, in the camera app, you'll see a ProRes option in the video tab.

ProRes Video: If you have an iPhone 13 Pro or Pro Max, iOS 15.1 added the ability to record ProRes video, which you can turn on by heading to Settings > Camera > Formats > ProRes.

There are tons of other features in iOS 15. It's similar to AR Live View in Google Maps. If you ride public transit, Maps will tell you when to get off, and once you've hopped off the bus or are outside the subway station, you can point your phone at the buildings in front of you to have Apple's augmented reality show you the way. The feature works in supported cities, which include New York, Philadelphia, San Diego, the San Francisco Bay Area, and Washington, DC. With CarPlay, you also can see details like medians, turn lanes, taxi lanes, bike lanes, and pedestrian crosswalks. When driving, Maps now shows highway interchanges in 3D so you have a better idea of exactly which lane you need to be in. You'll find more street-level details in commercial districts, elevation information in cities, and custom designs for landmarks like San Francisco's Golden Gate Bridge.

Apple's map data is getting even more detailed in iOS 15. The improved version of Apple Maps the company introduced in 2020 has rolled out to four new countries: Spain, Portugal, Italy, and Australia.
