Storage is a measure of how much information — for example, movies, photos, and software applications (apps) — you can store on a computing device. Storage can also affect your iPhone’s performance when handling such tasks as streaming favorite TV shows from the World Wide Web or downloading music.

Streaming refers to playing video or music content from the web (or from other devices) rather than playing a file stored on your iPhone. You can enjoy a lot of material online without ever downloading its full content to your phone — and given that the most storage endowed iPhone model has a relatively small amount of storage, that isn't a bad idea. See Chapters 18 and 20 for more about getting your music and movies online.

Your storage options with an iPhone 12 or 12 mini are 64, 128, and 256 gigabytes (GB), while 12 Pro and 12 Pro Max are 128, 256, and 512 gigabytes. You must choose the right amount of storage because you can’t open the unit and add more as you usually can with a desktop computer. However, Apple has thoughtfully provided iCloud, a service you can use to back up content to the Internet (you can read more about that in Chapter 4).

How much storage is enough for your iPhone? Here’s a guideline:

 If you like lots of media, such as movies or TV shows, you might need 512GB.

 For most people who manage a reasonable number of photos, download some music, and watch heavy-duty media such as movies online, 128GB may be sufficient. But if there’s any possibility you may take things up a notch in the future regarding media consumption and creation (such as the newest grandchild being on the way soon), you should probably seriously consider 256GB.

 If you simply want to check email, browse the web, keep your calendar up to date, and write short notes to yourself, 64GB likely is plenty.

Do you know how big a gigabyte (GB) is? Consider this: Just about any computer you buy today comes with a minimum of 256GB of storage. Computers have to tackle larger tasks than iPhones, so that number makes sense. The iPhone, which uses a technology called flash storage for storing data, is meant (to a great extent) to help you experience online media and email; it doesn’t have to store much since it pulls lots of content from the Internet. In the world of storage, 32GB for any kind of storage is puny if you keep lots of content (such as audio, video, and photos) on the device.

What’s the price for larger storage? For the iPhone 12, a 64GB unit costs $799; 128GB is $849; and 256GB will set you back $949. iPhone 12 mini with 64GB goes for $699, 128GB at $749, and 256GB for $849. iPhone 12 Pro with 128GB is $999; 256GB is $1099; and the model tops out at $1299 for 512GB. Not to be outdone, iPhone 12 Pro Max is the priciest: $1099 for 128GB; $1199 for 256GB; and $1,399 for 512GB. Note that prices may vary by carrier and where you buy your phone.
