It’s common to hear people complain that their phone has started to slow down, or that they’ve run out of space, or that the battery life is no longer any good.

A lot of these things can be caused by the various apps, files, and other random stuff that amasses the more you use your phone. Fortunately, it’s easy to clean it up, and Android has the tools to get the job done.

1. Uninstall Apps

The first place to start is to uninstall any apps you don’t use. We all tend to accumulate apps over time, leaving them there just in case we ever need them. If you don’t use them, uninstall them.

There’s no real benefit to keeping hold of apps that you don’t use. They clutter your app drawer, they take up space, and they can run in the background or go online without you realizing. If you want to see the amount of space an app is using, go to Settings > Storage > Apps, then select Sort by size from the menu.

uninstall apps

In addition to uninstalling apps you’ve downloaded, you can disable any system apps that you don’t need. When you disable an app, its icon gets hidden, any updates get removed, you can’t launch it, and it won’t run automatically.

To disable an app, go to Settings > Apps, then locate the app and tap Disable. To re-enable it, find the app again and tap Enable. Note that disabling only works for built-in system apps that can’t be uninstalled.

Get Rid of “Speed Booster” Apps

While you’re at it, you should get rid of any “performance-boosting” app you have installed. These rack up hundreds of millions of downloads, but are almost all junk.

These apps include task killers, RAM boosters, or anything else that promises to speed up your phone.

All these types of apps make grand claims that are rarely fulfilled. More often they will slow down your phone or drain your battery. They also tend to be packed with advertising, and many play fast and loose with your data privacy.

2. Free Up Space

Every phone comes with a limited amount of storage space that is several gigabytes less than what was advertised. Most devices lose up to 8GB to the operating system and pre-installed apps, and there’s no way to reclaim this.

clear data

Thus, you need to keep an eye on the space you do have available. There are several things you can do to keep plenty of storage free.

Go to Settings > Storage to see how your space is distributed between your apps, media, cached data, and other files.

Tap Apps, then Sort by size from the menu, and you can see how much space each app is taking up. This doesn’t just include the app files, but also any content (such as offline playlists in Spotify Is It Worth Upgrading to Spotify Premium? Is It Worth Upgrading to Spotify Premium? Spotify Free brings you tons of music at no cost, but are the extra features of Spotify Premium worth shelling out for? Let's find out... Read More ) and cached data.

If you don’t want to uninstall an app, you can tap Clear data to free up its space. However, this will completely reset the app, including any login details, saved settings, or scores.

What To Delete?

You don’t need to worry about Cached files, as this is managed by Android. When you use apps, certain files and data get cached so they can be restored quickly, making the app work faster. Android decides how large the cache can get and will delete its contents intelligently if it needs more space.

Images, Videos, and Audio are self explanatory, and they also give you an easy way to free up space. Unless you need to store your photos and videos on your phone for some reason (maybe you’re frequently out of range of Wi-Fi or 4G), you can use a cloud service to store them How to Select Which Google Photos to Back Up on Android How to Select Which Google Photos to Back Up on Android Is Google Photos backing up too much on your Android phone?

Misc Files

The other category is called Other or Misc. This is harder to call, as it contains literally all of your user data.

App settings, files, or game saves might be stored here, as will files you’ve dragged and dropped from your desktop Move Files from Mac to Android Without Android File Transfer Move Files from Mac to Android Without Android File Transfer If you need to transfer files between your Android device and Mac computer, these tools make it quick and easy. Read More . The Download folder is also here, containing everything you’ve downloaded through your browser — that’s often something that needs clearing out.

You may be able to identify what each one relates to, as they’re normally neatly sorted into folders. You can delete any files you don’t need, or any folders relating to apps you’ve uninstalled. If you aren’t sure what a file or folder is, it’s best to leave it alone.

other data

Of course, if you have a phone with a microSD slot, you don’t need to worry about freeing up space. Recent versions of Android enable you to move apps or large files to a card. Just tap the app’s name then select the Move to SD Card button.

3. Factory Reset

Finally, the simplest option: a factory reset. It’s a bit of a pain to have to do it, but if your phone has really slowed down, if it’s throwing up errors, or if it’s just generally buggy, a factory reset is the best option. Just make sure you’ve backed up everything first.

factory reset

A factory reset clears out everything from your device, including all your account information, returning it to the state it was in when you first bought it.

When you turn it back on, you will need to enter your Wi-Fi and Google account details. All your old apps should automatically start reinstalling. A lot of apps are now able to backup their data to your Google account (like Pokemon GO 10 Pokemon Go Tips that Every Beginner Needs To Know 10 Pokemon Go Tips that Every Beginner Needs To Know Pokemon Go can be a little daunting if you're just getting started, so we've made a list of 10 things you need to know to be the very best!

Your Spring Cleaning Apps?

It’s easy to clean your Android phone, and for the most part, the tools you need are built right into the operating system. While a little slowdown is inevitable over time, cleaning out the junk and getting rid of misbehaving apps every now and again should keep your phone running smoothly.

    If you want to backup your apps and games here's what to do.
    Download the app android assistant from the playstore.
    Once you open it tap on the tools bar (top right) and tap on app backup and restore. You will see all your apps that are on your phone (every single one of them).
    Mark the ones you want to backup and hit backup selected at the bottom. After this process is complete, open your file manager or my apps and scroll to android assistant appbackup & you'll see your backed up apps.
    You can back them up to a computer via the usb cable.

    My version of this goes something along this:

    Step 1) Erase System, Data, Cache, and Internal SD
    Step 2) Downloaded a Rom...
    Step 2.1)Extract the Rom...
    Step 2.2) Remove any useless garbage from System/Apps
    Step 2.3) Add any modifications that I may want (Audio Mod, More Applications to system, etc)
    Step 2.4) Rezip rom and move it to my internal SD card.
    Step 3) ??????????????
    Step 4) Profit
