Android as a platform has evolved quite a lot since its inception, improving considerably when it comes to cache and RAM management, which means that most cleaner and booster apps for Android aren’t really useful if you have a fairly new Android smartphone. However, if you’re still rocking an older Android device, which has become unbearably slow with time, then cleaner and booster apps can be used to marginally improve your device’s performance. While there are a ton of cleaner and booster apps on the Google Play Store, not all of them work as advertised and don’t have a significant enough performance impact. So, let’s take a look at some of the best cleaner and booster apps for Android that actually do work and can improve your device’s performance.

1. All-In-One Toolbox

Next up is SDMaid, a powerful file manager that is capable of helping you clear out some storage space on your smartphone. The app includes a CorpseFinder feature that can be used to detect and delete files left on your device by apps that you’ve already uninstalled, a system cleaner that automatically identifies junk files in your internal storage, an AppCleaner which scans for app files that can be deleted without hampering its performance, and a Duplicates feature that identifies duplicate files taking up space on your smartphone. While the app is free to use, some of its features are hidden behind a paywall and you’ll need to purchase SDMaid Pro in order to use them.

Files (formerly Files Go) by Google is also a great system cleaner that you can opt for if you don’t want to bother with cleaning up your device manually and are okay with depending on an app to do it for you. Predominantly a file explorer, Files by Google also includes a nifty file transfer feature and it also allows users to backup their files to the cloud, which can really come in handy when you’re looking to free up some space but don’t want to lose any files permanently. The app is quite easy to use and it categorizes junk files quite well, making it easy for you to delete files in bulk without worrying about losing any important files.

7. Nox Cleaner

Ace Cleaner is another pretty capable cleaner and speed booster for Android which has a really clean and minimal user interface. The app includes a couple of handy features that will help you speed up your old Android device, including a junk cleaner, a CPU cooler, a battery saver, and a duplicates remover. Ace Cleaner also packs in an app uninstaller which will allow you to remove apps in bulk, along with an app locker which allows you to secure sensitive apps.
