    there are lots of GPS settings and track frequency tweaks to make. I like 3m /3s for woods riding and 15m/15s for street riding. of course you can set each recording profile however you like.

    I honestly was surprised the reception was good right up to the entrance of caves and tunnels.

    I've never had a dedicated GPS. only my iPhone. It works as good or better than my buddies Montana. I just went down the Continental Dived and was it exclusively.Worked perfect and i wont be buying something my phone does. I have a waterproof case with a battery back up and mount it with a Ram X Mount. I also use the Galileo Pro App. with offline maps.

    It works everywhere. I just came back from 3 weeks in Spain and used it the entire time!

    Speaking about battery time: it's nice to have a cradle that supports a better method of charging besides USB. Anyhow I've made some short test to estimate battery time.
    With 3800mAh capacity tracking with LocusMap can be done for about 3 hours with display turned on and almost 10 hours with display turned off.
    It means without external charging it's still usable for shorter trips even using it with some dashboard mode as a bike computer + map but if you only use it for navigating a planned trip and tracking it can take a really long day.
    It's still far from Montana performance but much better than I've expected. Makes me think that this is indeed the time to turn rugged phones into navigation devices for outdoor activities taking their weaknesses into account. With an external battery pack they can easily serve you whole day or even for more days.
    It may take a while but I'll also make some tests regarding GPS and tracking accuracy. On main roads there's literally no difference between track details (less than 2%) so I'm keen to compare them on trails as well.
    First I'll need a good, stable holder that fits motorbikes and MTBs also.

    battery life varies wildly depending on whether other applications are being used, cellular service used, application efficiency, etc

    using airplane mode and locus I'll see lots of hours of single track, more than I want as far as riding goes. for street riding I normally play mp3s , use Google, text, etc and lots of other stuff, so I'll just leave it plugged in. for off road I'll just charge it at camp that night, normally with 30-60% left depending on usage.


    for accuracy tests, you can drop it into a camel bak and get good reads. , or use a cheap silicon mount from eBay. I normally see 3-5m accuracy depending on tree cover+canyons+water. actually water and canyons are the only accuracy issue getting greater than 3m, but then it becomes painfully obvious which way to go as a result of that terrain anyway ;-)

    over a short 150 mile trip today, I dropped the phone under my seat while trying to change songs and track accuracy dropped from 3m to about 15m until one of the kids picked it up:

    blue is +/-3m

    green is +/-4m

    red is +/-15m

    normally it's sitting in the armrest or cup holder in the car. on the bike it rarely if ever drops before 5m, unless it's slipped out of the holder and bouncing around by the forks, held on by the charging cord..... barely ;-) lol
