I'd estimate a maximum of one hour assuming a full charge before battery life is exhausted. This is based on own experiences with iPhone. Use an in-car charger though and you'll be perfectly fine.
Have been using TomTom on a HTC windows phone for around 6 years now and it's excellent.
Can't comment on Android phones, not sure of TomTom is available for them either, but with regards to the battery life, it does eat it up quite quickly. However most HTC phones use a mini usb port for charging and there are many holders and chargers for varying budgets out there.
Just out of interest has anybody had any issues with regard to a call coming through whilst using google maps? Used to be a problem on the older TomTom mobile apps, but not anymore.
