This one’s for more techy users or simply those who want to see the countless complex processes that occur when you boot up your Android device. They may take a little longer to open each time as a result, but the trade-off will be worth it for those who prioritize battery life. Once you’ve found the battery-hogging culprits, you can hibernate them, which means that they’ll use up less RAM and battery while running in the background.

Its main purpose is as a background app manager in that it tells you which apps are running in the background and which ones wake up your PC most often. Greenify has been around for a while, but its developers continue to regularly update it to keep its battery-saving goodness optimised and relevant to modern devices. Whatever your reasons, SetCPU is the kind of techy app that makes rooting worthwhile. Or perhaps you want to create a CPU profile specifically for gaming so tbat those 3D games running on your QHD smartphone display run as smoothly as possible. Why would you want to do this? Maybe you’re willing to sacrifice a bit of performance to get longer battery life or vice versa. If you’re technologically literate and feel confident about tweaking the voltage of your CPU on your Android device, then you can do so using SetCPU. Titanium has built a great reputation over the years turning the tedious, comprehensive process of backups into a cinch.

You can also set backups to be created at set times or do them manually. All your backed up data is encrypted and can be sent to external devices or cloud services including Box, Dropbox and Google Drive.

It’s capable of backing up and restoring and freezing all your apps, with the very in-app settings you had before creating the backup. Google’s built-in backup options for your phone are fine, but Titanium Backup takes things to another level. You need to create a second partition on your SD card for this to work, but it’s a real game-changer (pun intended). Your Android phone still thinks they’re in internal storage, when in reality they’re on your SD card and saving space. Link2SD moves these “obb” files to your SD card while creating a shortcut at their original destination.

Android may have a built-in “Move to SD” function for your apps, but that’s very limited, and if you have big games (kept as “obb” files) on your device, then the bulk of them will still stay on your phone.
