running a bit slower than usual,

there are a few steps that you can take

to bring your iPhone back up to speed.

First, restart your iPhone.

You can do that by holding the power button

and volume-up button at the same time.

Continue by sliding the bar to power off.

Next, make sure your iOS is up to date.

This will fix any bugs that may be bogging down your iPhone.

Now watch this video

on how to update your phone's operating system.

In this one, we show you how to update to iOS 15.

Before updating, we suggest backing up your iPhone.

You can do this either through an iCloud backup

or using your computer.

Additionally, your phone should be

at least 20% charged or connected to a power source

to ensure that it does not turn off during the update.

To update to iOS 15, navigate to settings.

Tap "General"

followed by "Software Update."

Choose "Upgrade to iOS 15."

Tap "Download and Install."

You'll see the terms and conditions pop up.

Take a moment to read through them.

Tap "Agree" to continue.

The update will begin.

After some time, your update should be completed.

Next, update your apps.

You may notice a lag on your phone due to an app.

Go to the app store on your phone.

Tap on your profile in the upper-right corner.

Scroll down to "Upcoming Automatic Updates."

Tap "Update All."

Delete any unused apps.

These apps can take up storage,

which will slow down an iPhone.

Long-press the icon on an app that you want to delete,

followed by tapping "Remove App."

Remove any unneeded widgets.

Long-press the widget and tap "Remove Widget."

Clear the cache on your phone by watching this video.

Clearing the cache on your web browser and certain apps

can free up space on your iPhone,

improve speed, and performance.

Before you clear the cache on your phone,

make sure you know your passwords,

since deleting your cache

will log you out of your accounts.

To clear the cache on your phone,

open the settings app and click Safari.

Tap "Clear History and Website Data."

Your device will double-check

that you want to clear Safari's data.

Click through the message that follows.

You can also clear the cache

and preserve history and cookies in Safari.

Tap "Advanced,"

then "Website Data."

Once here, you can either tap "Edit"

and remove individual sites,

or you can tap "Remove All Website Data,"

then tap "Remove Now."

To clear the cache on your iPhone apps,

you'll need to offload them.

Offloading an app will free up storage space

that the app uses while still keeping

its documents and data.

If and when you reinstall the app,

your data will be there.

First, open the settings app.

Select "General"

and tap "iPhone Storage."

Select the app you want to offload

and tap "Offload App."

Select "Offload App" from the pop-up window

to confirm your choice.

You can also delete the app if you no longer need it.

On the off chance that your phone has any malware,

try going through another restart

or even factory-resetting your phone.

Go to settings,

"General,"

and "Transfer or Reset iPhone."

Here, you can tap "Erase All Content and Settings."

Next, reduce the graphic settings.

It'll make your phone do less work.

Go to the settings.

Tap on "Accessibility,"

followed by "Motion."

Toggle "Reduce Motion" on.

Disable work that apps are doing in the background.

This isn't recommended

unless your phone is performing quite negatively.

To do this, go to your settings.

Tap "App Store."

Under "Automatic Downloads,"

toggle "Apps and App Updates" off.

Next, go back to your settings.

Tap "General,"

followed by "Background App Refresh."

Turn "Background App Refresh" off.

Finally, check your battery's health.

In settings, tap "Battery."

Tap "Battery Health."

The lower your maximum capacity,

the less of a charge your iPhone can hold.

If it's a low percentage,

it may be time to replace your battery.
