It's been a month now that the auto-sync option on my phone makes it upload 30 MB per day (in addition to my usual upload/download rate) and still download only a few hundreds of KB. It blew up my quota in only 10 days so I had to deactivate it. The only app that I installed at that time was the Google Doc app.
I recently reactivated the auto-sync and I unchecked the doc sync in:
Settings > Account > my account, but I'm still uploading 10 spare MB per day. I only kept Gmail, contacts and calendar syncing (just as before).
My questions are:
- Do you know what can cause this, why it changed without any visible reason ?
- Are there third-party apps using the Android auto-sync option to enable/disable their own syncing process ?
I use 3GWatchDog Pro, and this spare MB are shown under "Android System" so it's not very helpful.
If relevant, my device is the Motorola DEFY
