If you've just bought an iPhone getting started is easier than you think. Just use this free lesson as a guide.
The battery on your device should last for about 10 hours of normal use. When it's low, you'll need to charge it. There are two ways to charge the battery:
Although you can use an iPhone without a case, it's a good idea to purchase a case to prevent the body and screen from breaking if dropped. You can also buy a transparent screen protector to protect against scratches, but this is usually unnecessary because the iPhone is built with scratch-resistant glass.
The Apple Store has a variety of options to choose from. If you're not interested in the cases from in the Apple Store, don't worry—you can find hundreds of alternatives if you search online or in stores. No matter what you choose, a good case will go a long way toward protecting your device so you can enjoy it for years to come.
You should also make sure you have a soft, lint-free cloth for wiping fingerprints and smudges off the screen. Never use household cleaners, alcohol, or other abrasives.
