Americans check their phones, on average, 80 times a day.

You probably know some people who check their phones a lot more than that.

Smartphones are a big part of our lives, but you may not know some of the things your phone can do.

This TV remote doesn't work anymore. Then again, it could need new batteries. How do you find out for sure? You could go to the trouble of finding, maybe buying new batteries, or you can try a quick check with your phone.

Open the camera and point it directly at the remote at its infra-red emitter, then press any button on the remote. If you see a light, that means the remote still works, and it just needs new batteries.

The iPhone's Face ID is faster at unlocking a phone than entering a passcode, but sometimes you might not want someone unlocking your phone by pointing it at your face for any number
of reasons. To quickly lock your phone and require the passcode, just hold down the on/off button and the volume. A quick press takes a screenshot, but holding them down calls up the Emergency SOS and power off. But it'll also lock the phone requiring the passcode.

If you're trying to take a selfie with an Android device, just say "cheese". When the phone is in selfie-mode, you can say cheese, and the camera takes the photo.

You may forget where you parked, but Google and Siri have excellent memories. just say "remember where I parked", and Google or Siri will put a pin in it and give you walking directions
when you're ready to leave.

Google and Siri are also good at setting reminders for locations. "Remind me to take out the trash when I get home." "Remind me to get eggs when I get to the grocery store,"
and you'll get a notification the next you arrive in the parking lot.

These smartphones can do a lot more than browse the internet, text and take pictures.
