No matter what version of Google's mobile OS you're running, Android remains a tinkerer's dream. Because Android is open in a way that other mobile OSes aren't — we're looking at you, iOS — you can tweak and optimize the system's performance from A to Z. Whether we're talking cache cleaners, junk file hunters, CPU overclocking tools, app disablers or task automation tools, plenty of Android apps help you get more out of your phone. Here are 20 of our favorites.
Cheetah Mobile's Clean Master comes with a Junk Files tool for cleaning your phone's app and system cache as well as temp files. It also sports a memory-saving Phone Boost tool, an app manager and antivirus feature. While you can probably skip the task-killer-like features of Phone Boost, the Junk File tool is great at cleaning out widowed and temporary files, as well as cleaning out your system cache to free up phone storage. The app manager allows users to backup APKs, move apps to the SD card and uninstall apps.
All-in-One Toolbox is just that: a versatile all-in-one Android booster app. AIO Toolbox follows the model of many apps with a quick one-tap booster that cleans up cache, background apps, and memory; it also includes extras like an app manager, file manager, and CPU cooler (which kills background apps to reduce load). A handy "Easy Swipe" brings up a radial menu to quickly access utilities from your home screen or other apps. Where the app does suffer a mite bit is in organization, with tools split across a vertical feed and multiple tabs.
This tool will tell you about CPU usage, RAM and monitor other system services on your smartphone. Simple System Monitor also puts a file browser into the package. Some of the capabilities have been scaled back, given new tools in Android Nougat. Still, it's one of the most streamlined apps to you this type of vital information.
Ashampoo's an old standby when it comes to PC utilities, and the German software company has since branched out to develop mobile utility apps as well. Droid Optimizer is an all-in-one system optimization app that can be set for quick use, or for more detailed cleanup. A 1-Touch Speed Up mode can be set to clean the memory cache and stop background apps (with an optional whitelist), while a more selective Clean Up mode lets you go point by point. An App Manager lets you bulk uninstall apps or view permissions, while a Privacy Advisor flags apps with that have been granted permissions that might be abused for your review. There's even a handy automatic scheduling mode to automate cleanup or disable Wi-Fi at night.
Wondershare's MobileGo is a combination of Android and desktop application that does everything from system cleaning and optimization all the way up to phone backups. While the standalone Android app gives MobileGo a grab-bag of utilities such as a system cleaner and app manager, the addition of the desktop application provides backup and restore features that can work wired directly to your PC through a USB cable, or through Wi-Fi. Users can backup and restore apps, app data, contacts, SMS, calendars, call logs, music, video and photos.
Another comparable all-in-one Android optimization tool is DU Speed Booster, which comes with a Trash Cleaner for app cache and junk file cleaning, a one-touch accelerator, app manager, antivirus tool, privacy advisor and built-in Internet speed test. Again, the benefits of task-killing with accelerators are dubious, but DU Speed Booster's junk file / cache cleaner is a great way to free up internal storage space. And the app manager and other tools are also solid extras.
McAfee is best known for its desktop security products, but it's also moved into the mobile sphere with security and utility apps. Mobile Booster provides a variety of quick optimization tools to help you clean up your Android device. A one-button Quick Boost tool runs quick optimization and cache clearing, while dedicated Battery Saver, Storage Cleaner, and Memory Cleaner tools provide more tweaks for squeezing out more battery life, junk file cleaning, and background process cleaning, respectively.
