GoogleMaps Navigation

This is a copy of an enquiry about the GoogleMaps Directions/SatNav application which I submitted to the website today.

When I have used the HTC Desire as a SatNav using the Google Maps Navigation, I have had a power issue, details of which are described below.

The phone starts at full charge and is then plugged into the car cigar lighter socket and it starts charging (amber flashing light).  I then set Google Maps to navigate and started my journey.  At the end of the journey, I expected the phone to be fully charged but it showed less than half charge.

The following day I plugged the phone in for the return journey and it was at half charge.  At the end of this journey, the phone had lost so much battery charge that it immediately switched off.

I expected that all functions of the phone should be able to operate whilst on charge whether by mains or via car socket.  I can only deduce that the power consumed when GoogleMaps Navigate is on (i.e. screen, GPS and voice commands) is more than can be supplied by the charger.

My expectation was that even after a long journey using the SatNav functions of the HTC Desire, the phone should charged up fully at the end, ready to be used at the destination.

Can you comment on these issues and suggest a solution?  I am particularly keen to know if this phone has been tested on a typical car journey for power consumption and if the consumption exceeds the input charge.  I do not have an 'official' HTC car adaptor but I would be very happy to buy one if I can be convinced that the input charge would overcome this issue.

Perhaps there could be an update to the app which can be applied which causes it to consume less power and allows the phone to charge up?

I abandoned GoogleMaps navigation for the next journey and just left the phone to charge normally during the journey.  The car adapter fully charged the phone during the 3 hour journey from flat which at least proves the car adapter works.
