Okay, I took my Galaxy S4 running Android 4.4.2 down to Madera Canyon today to give The HAZ hiking app (1.8.3) a test. BTW Joe it is a great app with easy to use functions in my book! Excellent instructions as well. Good job!
I also ran my Garmin Oregon 450 on the hike so I could compare the results. I haven't done that yet, but I am sure it will be interesting.
Anyway, the one thing I was worried about was the phone battery running out of juice before the hike was done, which it did. I didn't take a camera with me, so I was also snapping pictures with the phone. This probably didn't help matters. When I started the hike (which took around 6 hours) the phone was at 93 percent battery. I had it in power saver mode. I have already disabled many of the apps to help with battery life, but still have some like Facebook running. Perhaps I need to disable more, but don't like the idea of shutting some of them down. Anyway, I almost finished the hike when the battery became critical, so I paused and saved the track, put the phone into airplane mode, and waited til I got home and charged it up awhile before checking on the track again. It was still there, looked good, so I successfully sent it to route manager to play with later. Nice!
Now to get the phone battery to last longer (looks like I may need to have it in airplane mode when I start hiking?).
(By the way, I loaded the current version 1.8.3 from google play before September 8th).
