I usually use about 600MB of my 1GB allowance every month, therefore on average about 20MB a day. My new month began on Friday but I didn't leave the house all day and was using my home wifi. I went out yesterday and used my phone as normal and not excessively. Getting home, I checked my usage and I've already used 120MB of my 1GB allowance in just two days.
I was wondering if there's a known issue with data usage at the minute. I used a little bit more data than normal in the first few days of having the phone back in December but it soon sorted itself out. I haven't changed any of my settings. Most notifications (Email, Facebook etc.) are switched off, my location settings are switched off and I've opted out of sending diagnostics to o2.
