I think Charge mode in traffic is not worth it, but if you are on a motorway the charge mode doesn't seem to hit the mpg quite as bad. This is not scientific - just watching the mpg readout and seeing what happened. E-Save will charge to some extent too. If the weather is cold try not to use the electric at the start of the journey. Use it once the car (cabin) is warmed up.
