I'm pretty sure others already asked this, but I haven't found any answers, so I ask it here: My P1000 has a bit too high data usage, and I haven't got any idea why. If I left the mobile data on, after I checked my emails, it can generate around 4-6 MBytes of trafic in around 10 minutes, and it does it in about every 3-4 hours, so in a day it easily can generate 20-30 Mbytes of trafic without even touching the tablet. Of course my first idea was to install a data monitoring app, to check what causes this insane trafic, and each and every app said, it was the Android system itself. I can't figure out which service does it, but it's the system itself, that's sure. It's not really a problem on Wi-FI, but on 3G it is. I turned off almost every syncronization services, only Gmail, and Chrome sync are stayed on.
My tab is a P1000 (GSM version) and I have the latest stable official CM9.1 on it.
Any help would be apriciated.
