1. Greenify
Getting the most from your phone’s battery is always key. Lollipop may have its own set of battery-saving tools, and many phones now offer power-saving modes, but these should be seen as a last resort.
Greenify sits in the background helping to regulate how much battery various apps are using. It freezes the apps you tell it to when you’re not using them, and instantly defrosts them when you need to gain access.
2. Clean Master
Nobody likes having a slow device, and Android somehow manages to grab digital detritus like a magnet in a junkyard. Clean Master is the mop and bucket you need to scrub your phone or tablet clean.
Clean Master’s Junk File Cleaning feature scans your Android device and chucks out any unwanted cache and residual files.
3. Tasker
If you really want to tinker with Android, Tasker is a brilliant way of automating much of the functions you'd normally do manually. It takes a little getting your head around, but the scope here is enormous - especially if you have root access on your phone.
You can train your phone to open Spotify when you put your headphones in, for example, or automatically respond to texts with your street address. If you can feed it the instructions, Tasker can automate the rest.
4. Opera Max
Unless you’re lucky enough to have unlimited data on your phone, or a bottomless wallet, you’ll want to get the most out of your data package.
This is where Opera Max comes in. It crunches down the size of images and videos, speeds up website load times, and typically saves you from around a third to almost half of your general data use. You can restrict some apps to only ever connect via Wi-Fi, and temporarily turn off connections if you want to save some data for the end of the month.
