[aprssig] Great Android app U2APRS

That may be the app, but it's probably also the always-on GPS and 
always-active data connection.

You'll see the same thing under WinMo with APRSISCE/32.  And if you have 
Bluetooth, WiFi, GPS, and a busy data connection, the phone can almost 
get too hot to handle.  Oh, and battery life under that level of full 
load is about 1 hour.  Drop the BT and WiFi, but keep the GPS and data, 
and you can get 2-3 hours monitoring 200 mile radius via APRS-IS.  Drop 
the GPS and you're up to about 6 hours of APRS-IS monitoring.  Drop it 
all and use it like a dumb phone, and you're back to 4-5 DAYS on one charge.

Yep, phones were made to be phones that are interactively used by people 
on a VERY infrequent basis.  They really weren't designed to run 
applications 24x7 with no required user interaction.
