Top Reasons Your Phone is Running Slow

It’s a tired cliche, but phones are like mini computers in your pocket. That means, they suffer from many of the same maladies that can afflict old PCs. These include:

  • Running too many apps or programs
  • Having too little storage space
  • Using an out-of-date operating system
  • Having an ageing battery
  • Getting too hot

In this guide we'll tell you:

How to Speed Up a Slow Phone

Despite the hotly-contested differences between iOS and Android phones, the essential functioning of both systems is similar. As such, there some general tips that will help you recover the oomph your phone loses over time.

Clear Your Phone’s Cache

Clear Safari Data from iPhone Small

There’s a good chance that you use your phone for browsing the internet more than you use your actual computer. This means your phone’s web browser, whether that’s Chrome, Safari or Opera, is storing loads of data. Deleting it can save you storage space, and speed up your phone’s browser, too.

Clear the Cache on an iPhone

To clear the cache, tap Settings > Safari > Clear History and Website Data

If you just want to clear the website data collected, you’ll need to tap Settings > Safari > Advanced > Website Data > Remove all website data

Clear Cache for Android (using Chrome)

This is using the Chrome app, if you use an alternative browser, the steps might be different Open Chrome > More (the three vertically-aligned dots) > History > Clear browsing data > Select time period. Then, check the boxes next to “Cookies and site data” and “Cached files and images” > Clear Data

How to Update Your Phone’s Operating System

How to update Android. Why is my phone so slow?

You might hear some people complain about updates to their phone’s operating system. Perhaps they don’t like the new design, or they’re annoyed it’ll take up more storage on their phones.

However, each iteration of Android or iOS comes with improvements to the speed and security features, plus bug fixes that can have a speed boost.

How to Update iOS

On an iPhone or iPad, tap Settings > General > Software Update

You can also turn on automatic updates, which will update iOS when your phone is plugged in and charging between 2am-5am – neat, right?

How to update Android

It’s always worth backing up your data before you start to update Android, when you've done that go to Settings > About Phone/Device > Software Update (or similar). Your phone will now search for an update. If there’s an update available you’ll be prompted to install it.

You can also schedule the update for later, or turn on automatic downloads.

How to Delete Apps You Don’t Use

Deleting apps might not seem like the most obvious way to speed up a phone. After all, if you’re not using them, how can they slow you down? However, having more storage space on your phone means that its processor can work more efficiently. So, if you’re not using apps, it’s a no-brainer to free up some space by removing them.

How to Delete Apps on an iPhoneHow to delete iPhone Apps

There are two ways to remove apps on an iPhone

  1. Delete Apps – this removes an app and all its data
  2. Offload Apps – this removes an app, but keeps a backup of its data. This is handy in case you want to reinstall the app

The easiest way to delete iPhone apps is by simply pressing and holding the app you want to delete and, once it begins to dance around on your screen, tap the “x” in the top left corner.

However, by dipping into your settings menu you’ll see the apps arranged by size, along with the last time you opened it.

Tap Settings > General > iPhone Storage > Select app > Delete app.

You can also Offload apps which frees up the storage required by the app, but the documents and data it creates during usage is retained. Useful if you’re in a pinch and don’t have much room to play with.

To do this, tap Settings > General > iPhone Storage > Offload Unused Apps > Enable.

How to delete apps on Android phones

You might not be able to delete all the apps on your Android phone, but you can disable them so they won’t show on your app list.

Deleting an app Settings > Apps & notifications. Select the app you want to uninstall. Or tap See all apps or App info if you can’t find it, then tap Uninstall

Disabling apps follows the same process.

How to Close Apps

How to close apps on Android. Why is my phone so slow?

Apple and Google both maintain that dormant apps that are open in the background do not hinder your phone’s performance. However, if there are apps still working away in the background – for example if they are using your location – then these will affect your phone’s speed.

Closing these apps will stop this process and give your phone a speed boost.

How to close apps on iOS

Double press Home button then Swipe up on the apps you want to close

How to close apps on Android

There are a few ways to close apps on Android, but this is the easiest.

Tap the Overview button (usually, the square right of the Home button, on Samsung’s it's on the left) > You’ll then see a list of open apps > Drag the app off screen or tap the “X” in the top corner of the app window

Speed Up a Slow iPhone

There are a few specific tricks you can use to speed up a slow iPhone.

Turn off iPhone Siri and Search suggestions

Siri suggestions

Your iPhone’s digital assistant, Siri, is constantly indexing apps and content to help make your life easier. The theory is that you’ll use Siri to search for things online, and on your phone itself which will speed up the way you use your phone.

However, for older iPhones, this can lead to some slowdown. You can alleviate the strain Siri puts on your phone by switching off some of the apps it suggests.

How to stop Siri suggestions

Tap Settings > Siri & Search > Choose app > Search & Siri Suggestions > Show App

Stop Automatic Background Processes

iPhones are constantly working in the background to try to make your experience as slick as possible. This can be anything from automatically downloading synced content from Apple Music or the App Store, or it could scanning the News app for new stories, or Amazon for product recommendations.

However, on older iPhones in particular, this might make your phone a bit sluggish.

How to stop background app processes

Tap Settings > iTunes & App Stores > Automatic Downloads


Tap Settings > General > Background App Refresh > Choose App

Speed Up an Android Phone

There are also some unique ways to speed up an ageing Android phone as well.

Install Lite Versions of Apps

Install Facebook Lite from the Google Play Store. Why is my phone so slow?

As there are so many Android phones available, it’s easy to understand that not all of them will be able to run apps at full speed. As such, some developers have taken to creating Lite versions of their apps which require less processing power.

There’s a Lite version of Facebook, for example, and a Messenger Lite. These were designed to work on cheap, lower-power phones running on 2G connections. But, these apps can be installed on any Android phone – simply download them from the Play Store.

Try a Different Launcher

The Launcher, is, effectively an Android phone’s home screen. It’s where you can see your apps, widgets and certain notifications. Android phones come with Launchers already installed, and these are often specific to each manufacturer.

However, some manufacturers, such as Samsung and LG, have been known to use Launchers that are loaded with bloatware. Fortunately, you can install different Launchers, which will require less heavy lifting from your phone.

Installing a new launcher is similar to installing a new app. You’ll need to visit the app store, download the launcher and then, when you tap the home button, your phone will ask you which launcher you want to be your default option. Popular launchers include the Nova launcher, Lean Launcher and (perhaps surprisingly) the Microsoft Launcher.

Google's Android Support pages are a good place to turn to if you're having problems

What If None of This Works?

Try factoring-resetting your phone – it'll clear all the unecessary data your phone might have collected along the way, but make sure you back up all your important stuff such as your contacts and photos.

If that still can't give your phone a speed boost, the only thing left to do might be getting a new phone. We've rounded up the Best Phones for 2019 to make your choice super easy.
