Love the Treo 270 but have also noticed more "No Service" conditions compared to the nokia 5160 cheapo phone with the same provider with the devices side by side. I wonder if part of the battery saver logic, if the receiver is not getting cranked up when there is low signal, but rather going to the no service condition. Nokia still shows some signal. Any others have a similar observation?

What exactly does the extended battery saver software do?
