I need any/all tips I can get for maximizing my battery life when geotagging. I'm going to Europe. Voice and data roaming will be off. Will it constantly be searching, running down the battery? I'd basically like to let Geotag Photos Pro run in my pocket all day. I figure I'll turn off Wifi and Bluetooth, and crank the screen brightness down. I have a battery charging case also. What else can be done? Thanks. ---------- I also plan to toggle location services off for everything but the geotagging app and Find My iPhone.
