My girlfriend as just recently upgraded to the SGS and loves the phone, but is having a problem with how much data the phone seems to be using even when she is just using it for facebook and browsing the Android market. The phone also uses around 4mb of data over night when the phone is idle.
She calculated that she uses around 18mb of data a day without dowloading anything, just occasional facebook use and browsing, to me this is too much as if this happens everyday then she will go over the 500mb fair usage policy on her contract with Orange. I have an Xperia X10 and have never gone over 500mb in a month and I sometimes stream movies off youtube and download games etc.
Basically i just wanted to know if there is anything she can do to cut the data usage down while the phone is idle? any other tips would also be much appreciated.
