Why the FBI Says to Reboot Your Phone Weekly

The Federal Bureau of Investigation (FBI) advises something almost embarrassingly simple: restart your phone regularly. Cybersecurity experts back the advice, and it costs nothing. If you run a business off your phone, it's worth doing. For more on protecting your business and your data, browse our security and IT resources.

What a reboot clears out

Your phone holds contacts, photos, banking apps and probably a few work logins. Most people protect that with a passcode and call it done.

Restarting at least once a week adds a cheap extra layer. It clears temporary files, resets system processes and shuts down background apps that have been running for days. Over time that clutter builds up, and it can leave your phone slower and a little more exposed. A fresh start also frees up memory that stuck processes were hogging, so the phone often feels quicker afterward.

How reboots interrupt zero-click attacks

A zero-click exploit is an attack that needs nothing from you. You don't tap a link or open a file. The attacker goes after a flaw in the operating system or an app and gets in on their own, often to pull out sensitive information.

A restart disrupts those malicious processes and shuts the window they were using. Think of it as wiping the slate: the phone comes back up in a cleaner state, and any leftover malicious code that was quietly running in the background gets flushed out. It won't stop every attack, and it's no substitute for updates. It does make an attacker's job harder.

Other habits worth having

A reboot is one habit among several. If you rely on your phone for work, account hygiene matters just as much, so it's worth reading why default cybersecurity settings can be dangerous. Security experts also recommend these practices:

• Keep the operating system and your apps updated. Updates often carry patches for newly discovered threats.
• Use a strong, unique passcode or biometrics such as a fingerprint or face scan. Add two-factor authentication (2FA) on important accounts so a stolen password isn't enough.
• Review app permissions and turn off anything an app doesn't need. Check them again now and then, because apps ask for more over time.
• Skip unsecured public Wi-Fi where you can, and use a VPN when you must handle sensitive information on a public network. A VPN encrypts your data so it's harder to intercept.
• Turn on Find My Device and remote wipe, so a lost or stolen phone can be located or erased.

Convenience versus security

Most of us pick convenience when the two collide. Restarting a phone is one of the few security steps that barely costs any. Pair it with regular updates and you've covered a lot of ground without changing how you use the device. Put a weekly reminder on your calendar if you need one.

Your business phone line

The same thinking applies to how your business handles calls. If your team takes calls on mobile devices, a cloud phone system keeps your numbers and call data off personal hardware and on a network built for 99.999% uptime. CallSprout can even turn smartphones and tablets into full-featured dialers, so staff stay reachable without exposing personal contact details.
