Because GPS itself is using lot's of battery I'm looking for something that would preserve as much battery as possible, therefor the requirements are:
1) no data connection requirement (google types are not acceptable)
2) has voice turn-by-turn notifications
3) can work in standby mode (or at least has an option to turn off display)
4) can work in the background
I've tried tomtom, but it fails 3 and 4...
TomTom is released on Android? When did that happen? Thanks to the rest of you, too - I have some other things to look at, then.
First of all, I ride in London, so my research has been based on navigating within the UK. I thought I'd looks at everything, but it appears that I've missed a couple of obvious ones.
So here's what I've come up with:
I'm using an experimental navigator called Androad (google it - it's not on the market). I find that it gives me the best route for my daily commute, although it's not without issues. It does not give me my current speed, which I like to see, the turn directions overwrite the arrows you can can't see the distances, and the voice navigation gets its lefts and rights confused so is a bit like taking directions from my wife. However, it does a great job routing primarily along cycle routes where it can, so I'm inclined to use it over the alternative.
BikeHub uses the CycleStreets API to do its routing, and is quite nicely polished. It doesn't give you the ability to create a location database, and although you can route via multiple locations, it is difficult to enter multiple points not having a location database to reference. This said, it does provide routes that I would never have considered possible, so it's interesting to see.
I will have a look at the apps mentioned elsewhere in this thread, and see how they work.
Another point that has been mentioned is that if using a charger. I have done this myself, although I never use it because my phone lasts much longer than my commute. My charger solution involved buying a USB car charger from amazon and a 3S lipo battery (11.1V). I do quite a bit of radio controlled helicopter flying, so I'm kitted out for lipo, although I see no reason that the same solution shouldn't work for LiFe, which is often used for bicycle lights. I ripped the guts out of the charger, connected the battery directly the input and my phone to the other end. I have yet to get my hands on a LiFe battery to try this, so don't try it until you hear from me again because you might damage your phone.
Hope this helps.
