Bloatware is a type of software which is installed by the product vendor (like Samsung) on top of the Android operating system in your mobile phone. But do you need all this extra software? The name clarifies; it makes your mobile bloated. Much of the utilities and services installed on your phone are simply not required, and at times may be annoying or consuming a fair bit of battery. Uninstalling a lot of these may buy you an extra day or two of battery power.
