One of my recent posts showed that the latest Facebook application increased "signaling" traffic significantly over the previous version (see "
ALU: Signaling Issue with New Facebook" -
here, with a comment from ALU providing additional explanation).
Facebook is not alone - some application could consume your monthly quota, even when in background. A
Verizon support page warns about several
Android applications that "
might have serious negative effects on your device". One of the reasons to enter list is "
Unexpected high data usage". The page has 13 applications, all games. Most are there since they keep the device from going to sleep mode, shortening batter life.
Some consume "
a large amount of data while running in the background":
- Hill Climb Racing - A device left untouched with the app running could use as much as 6.4MB in 24 hours, or 190MB in a 30 day period
- Jail Escape - A device left untouched with the app running could use as much as 17MB in a 24 hour period, or more than half a gigabyte in 30 day period (removed from Google Play)
