Bests & Worsts Reviews from Amazon

This type of product is a digital snake oil for your phone. Your Android smartphone is actually smart about how it manages applications and resources. Apps like this one work against your phone and any effort it will make to maximize its battery life. Yes, there are poorly written apps out there that waste your phone's battery life but you should uninstall those after checking the Battery Usage screen in your phone's Settings. Previously "RAM booster" apps were known as "Task Killers". If you need more on what ram boosters or task killers do, please search the web for "android task killer" and read the lifehacker post on these type of apps.
