I am using Opera in Offroad Mode. The traffic savings were constantly around 80%. And then today, all over sudden, while I was browsing the news Opera caused approx. 25 MB of traffic and the savings counter dropped to 50%. I was just browsing ordinary news web sites. Any clue what may have happened? I opened the very same pages with my desktop computer and loading the page I suspect to have caused this traffic peak caused 2.4 M (not 25 (!)) of traffic.
Edit: Yes, I did check in the app manager... it was Opera which caused the traffic.
I am at my wits end...
