Setting your display timeout is important not only for preserving battery life, but also for securing your Samsung Galaxy S7.

It's a widely-known fact that one of the largest drains on your smartphone battery is the display. The longer it's lit up, the quicker you'll notice your battery drain. By default, the Galaxy S7's display will go black after 30 seconds. If you find your screen goes dark way too fast, you might want to look into using the Smart Stay feature, which will keep the phone display on and bright for as long as a pair of eyes are looking at the screen.

But if Smart Stay doesn't work too well for you — and you wouldn't be alone if that's the case — you'll want to adjust the screen timeout settings to better serve your needs. It's a quick switch, so if for whatever reason you need to keep your screen on for up to 30 minutes, you can. But keep in mind that doing so means that if you were to misplace your Galaxy S7, anyone who found it unlocked would have full access to all your sensitive data.

Battery-saving tip

On basically the opposite end of the spectrum, if you've found that your phone's display sometimes turned on while bouncing around in your bag or pocket, you should flip on the "Keep screen turned off" function, which uses the Galaxy S7's light sensors to determine when it's in a pocket or bag, and then restricts the phone's display from coming on. Clever!
