I get horrible reception at work, but have wifi. I put it in airplane mode then turn on wifi while there. That way the cell radio doesn't pull the battery down.
Best option really is having a charger at work though.
If I put it in airplane mode while connected to wifi can I still receive anything at all? Never used airplane mode but the way I understand it is it basically kills all service.
