With the Optimus Elite, it is not "the fact that a bunch of apps are *constantly* trying to send and receive data" it is that the Elite has a hard time connecting to and maintaining a reliable 3G connection. It is constantly getting 3G then dropping off of 3G and reconnecting. Sometimes throwing the device into airplane more for a couple seconds will fix this, but not always.
The TWS bug is also rampant in this device. I typically have upwards of 70% TWS and that is even with the TWS bug fix (put device into airplane mode just after boot and then toggle it off after a minute or so).
