Will E63, Ink Weather, UC Desktop, Google Maps and other software quietly waste traffic? How to deal with this?

If you quit them, you won't run networking in the background to consume traffic. You can also close all processes related to them through the next process management software (there are many searches on 3g). Ink, uc, etc. It opens automatically when it opens. Your next mobile phone guard, just turn off the ink, uc and so on. Don't want it to stay open.
