I find I have had the annoyance of an App that cllaims to be a Battery Booster but really
is not and is just Malware and Adware.
Battery Booster (2 x Battery) is the fellow.
Actually to be fair to the Author, the permissions very clearly state what this app does in that
it funds itself by malware and adware and it just shows that myself and other should read the permissions you are granting more carefully.
What is more worrying is at the end of the description. In an update dated 11th October the Author very
clearly states that "This App is a pure placebo. It does not boost your battery life. It is a prank App.....have fun".
Have fun releasing malware on your device that is then. The definition of a Placebo is a treatment
that is benign, many would say that this will affect your Android device adversely and is not benign.
So, read the permissions first and be aware of security issues.
