Default Updates security.policy battery drain

I got my S4 Mini for about a month and a half now, but since a few weeks my battery has been draining rather quick..
When going to school i listen to music, Whatsapp a bit and browse 9Gag (via the app) a bit also while i'm in the train and bus (about 1 hour and 15 minutes in total to get to college) and my battery is drained about 25% in 45 minutes

I found out that Updates security.policy is draining my battery quite a lot, and it's also using some data

Anyone knows what this service is, and if i could disable it?

I've added some screenshots from Better Battery Stats
