My data usage has spiked since just yesterday. Confused.

For some reason my usage spiked yesterday and so far today it's the same. I usually use 1GB per day. You can see the Received and Sent usage has spiked. Have not done anything different. Any ideas? Thanks!

That's not a grotesque amount. Patches?

For me it's just so much more above my daily average use. To go from 62.3 and 50.4 to 339 and 581MB sent is quite the leap. What do mean by patches? Thanks.
