it’s still shocking in every way possible.
What phone? Not all phones are equal when it comes to GPS etc.
Some early ‘droids in particular are a bit flaky. I get a pretty reliable GPS tracks on my iPhone 4 and the thread above mentions some reliable ‘droids to use.
I did a three day trip a couple of weeks ago and happily recorded 160 miles of track over 11 hours by just adding an external battery (no messing about with airplane mode etc)
(so no data, bluetooth or wifi) with brightness turned down
Why have the screen on at all? it is by far the biggest drain.
