Phone feeling slower than usual? Don't forget to do this regularly

To prevent background apps from running amok, draining your phone battery, or even slowing it down significantly, pick up this simple, weekly routine.

When was the last time you restarted your phone? And I don't mean opening up the active apps tray and swiping them all away. When was the last time you turned off the device completely and then turned it back on?

Restarting a phone is typically brought up when you're experiencing lag, misfunctioning apps, and other software defects, but it's also a healthy practice even if your phone is working as intended, or is the best on the market. You can compare it to giving your car an oil change; it's not mandatory, but after every couple of thousands of miles driven, a refresh can mean all the difference in performance.

In a phone's case, restarting it will clear out any background apps, heating issues, memory problems, and troubles with call signal -- even if it's only for the short term. Most importantly, you're giving the device a fresh start, which translates to smoother performance and slower-declining battery life. So, here's how to do just that, as well as some of my other best practices.

How to restart your iPhone or Android

1. Using the power button

For iPhone, you'd think that tapping and holding the right-side power button would prompt you with the reset settings, but that's sadly not the case.

Instead, you'll need to tap and hold both the power button and the volume down key on the left side. After three seconds, a power-off slider should appear on the screen. Swipe across to confirm the action.

For Android, tapping and holding the power button may follow a similar behavior as the iPhone, activating the built-in voice assistant instead of the reset prompt. If that happens, press both the power button and the volume down key for three seconds or until you're given the option to power off or restart the phone.

Note: On most Android phones, you'll have the ability to modify your power button so that it triggers the reset options by default instead of the voice assistant. You can't do this on an iPhone though.

2. Restarting, the hands-free way

If you're feeling lazy, there are several ways to restart your phone with even less effort.

On iPhones running iOS 16, you can now tell Siri to restart your device. It'll ask for your confirmation before doing so.

Also: How to clear the cache on your iPhone (and why you should)

For Android, manufacturers like Samsung give you the option to set optimized restarts, meaning the phone will automatically reset itself when it notices slowdowns and you're not using it. You can turn the feature on by going to your Settings > Battery and device care > scrolling down to Auto optimization > and toggling it.

From my experience, auto optimization typically occurs in the middle of my sleep. You'll know it happened when you unlock your phone and it asks you to use your pin or pattern instead of the biometric security.

In terms of how often you should be restarting your phone, I usually recommend doing it on a weekly basis, every Wednesday or Thursday. This way, you have a refreshed device to tackle the second half of the week.
