Well, try getting your hands on an HTC Kaiser. Then get the app "PocketDrake" (pocketdrake.cz) That has all the features, and DOESN"T NEED 3-G, 4-G, WiFi, or ANYTHING other than a GPS signal (use an external reciever...gps loves battery) just make sure to download your PQ's and GPX files before you head off. Its like looking at geocaching.com!

I wonder what the batteries (non rechargables) BEFORE alkaline would last. 3 Seconds? Also, batteries don't last forever. Period.

Set the brightness to minimum. The higher the batteries mA rating, the better it is. Sometimes, if you plug in a phone, set it correctly, and take out the batteries (with it still plugged in) it should stay on. Power Only is probably "charge, no sync" sometimes, you turn off the charging if you want to SYNC it with a laptop, as you if you charge it it DIScharges the computer's battery. It could do that, too. Try a Lithium-Ion battery. They may be pricy, but they pack a lot og power. Also, GPS recievers tend to munch on batteries and devour them. So if you can, turn off GPS when not using it.

The reason for the .1 rule is so: You go out to find a cache There is no .1 mile rule You think you found the cache You log the wrong cache Get it? Not good.
