Take a look at your surroundings right now, and you'll likely see almost everyone carrying a smartphone. You may even be reading this article on your smartphone.

What do service providers say?

Your network could come into play here, so we started our quest for answers by looking up what mobile companies and smartphone service providers recommend for restarting frequency.

T-Mobile suggests restarting an iPhone or Android device "at least once a week," according to its support website.

Their website explains that phones can occasionally disconnect from the T-Mobile network, and when that happens, restarting the phone can clear up any connectivity or speed issues.

T-Mobile also lists other benefits to weekly smartphone restarts. Benefits include helping to clear memory, improving app speed, preventing the phone from overheating and improving Wi-Fi calling connectivity.

Tech experts weigh in on restart frequency

Tech experts have differing opinions, though. David Attard, a digital consultant for, suggested smartphone users restart their devices at least twice a month in an interview with SheFinds.

"Restarting the phone just stops all applications that may be running in the background," he said. "This means with nothing running in the background, your phone will run faster. This also improves the battery life of your iPhone."

Similarly, restarting your smartphone can help prevent crashes due to outdated or improperly working code that gets stuck with new app installations or uninstalls, according to tech consultant Bob Motamedi.

"Sometimes these remnants are incompatible or improperly removed after installation or uninstallation," he told Reader's Digest. "Restarting your phone will eliminate most of these issues and will get your phone working better."

Should you restart your phone every day, then? Attard says semi-monthly or weekly reboots are more than sufficient.

"Anything more than that is completely unnecessary," Attard concluded.
