I have a FairPhone One. From time to time I look in the system settings and the battery usage to see what is draining the battery. I've disabled anything I don't use, including a number of builtins from Google. I've also looked at other apps and if their permissions are in balance with what they're supposed to do. (Simple games should not have access to my phone calls.)
What is YGPS and why does it have the longest possible list of permissions? Can I safely disable it?
