Yes, they're often described as a minicomputer in your pocket. But you also have a radio, a flashlight — even a level for when you're doing handiwork around the house.
As smartphones added features through the years, people began relying on them to take pictures, be their address book, wake them up in the morning and manage their appointments. More than 8 in 10 people age 50 and older own and use a smartphone, including 7 in 10 who are 70 and older, according to an AARP research report released this year.
But your smartphone can do much more. Here are 19 additional ways to use your iPhone or Android device and how to tap into those capabilities. All of the features are either baked into your phone already or available as free downloads from Apple's App Store or the Google Play store for Android.
Tip: Sick of fumbling with your phone? Some of the functions here can be launched just by talking to it. For iPhones, say “Hey, Siri,” then state your command. For Android phones, say “Hey, Google,” then your command.
1. Battery tester for remote controls
Both: See if the batteries in your TV remote controls have enough power to do their jobs. Launch the Camera app and switch to the front-facing selfie camera, though in some cases the rear camera also works. Point your remote control at the camera then press and hold any button on the remote. If all is well, you'll see a pinkish-purplish light flickering from the tip of the remote control, the infrared beam that sends signals to your TV and other tech gear. Replace the remote control batteries if the flickering light is especially dim or you don't see any light at all.
2. Calculator
Both: Open the Calculator app. You can perform basic math functions when holding the phone vertically. Rotate the phone on its side to summon a scientific calculator that can give you square roots, sines and other more advanced actions.

3. Document scanner
iPhone: Open the Notes app. Tap the icon in the lower right corner. Tap the camera icon at the bottom of the screen and select Scan Documents. Place the document in view of the camera. If your device is in Auto mode, your document will automatically scan. To manually capture a scan, tap the shutter button or one of the volume buttons. To adjust the edges of the scan, drag the corners to fit your document, then tap Keep Scan or Done.
