iOS 13 has improved the Mail interface - instead of tapping and holding until a menu appears and then scrolling left and right to find your tool (which you can still do if you prefer), there is now a much more aesthetically pleasing and useful toolbar that you can open with a single tap. From this bar you can format your text, insert photos, take a photo, attach files, scan a document and insert a sketch.

Wireless charging is quick and convenient, with no Lightning cable required. Apple's latest devices all support the Qi wireless charging standard, which means there are many choices when it comes to charging pads, stands and other products. Even AirPods with a wireless charging case can be placed on a wireless charger, just like an iPhone. And iPhones can be charged wirelessly without removing a case.

After a less-than-stellar debut, Apple has continued to improve upon its Maps app with each new iOS iteration, including iOS 13. In addition to adding the Look Around feature (equivalent to Google's Street View) and letting you automatically share your ETA, iOS 13 also tweaks the Favorites feature and adds a Collections feature which lets you create a list of locations that you can share.

Animoji debuted with iOS 11 as fun Messages feature involving animated characters that use your iPhone's front-facing camera to mimic your facial movements and expressions. iOS 12 introduced Memoji which are basically customizable human Animoji. iOS 13 now lets you use both Memoji and Animoji as your profile picture. Not only can you use them as your own avatar, but you can create Animoji and Memoji profile pics for your contacts as well.
