Help Turn off anything non-essential

[jeremy1701]

Hello,
I'm planning a pretty extensive backcountry hike in the next few days and I think I'm going to ditch my GPS/Camera for the Droid. I found this Goal 0 Nomad solar charger that seems to work pretty good for charging... I think I may have a shot at a permanent replacement.

That leads to me to need to maximize my battery life. I'll use airplane mode
to turn off any radios (BT, WiFi, Cell) and use off-line map mode while I track my progress using EveryTrail. Is there a better (more thorough) way to disable radio?

Testing it out this past weekend, I seem to have been able to completely nix any cell standy by or radio related processes. Is there anything else I can 'kill'? What about widgets? They seem to take up battery under com.htc.launcher. Is it worth it to get ride of them? The only thing I need is the GPS tracks and the camera/camcorder.

Update:

I used my Droid exclusively through out this entire trip. I used Everytrail to keep my tracks, I got a ton of photos/videos, I read trip reports and used downloaded topo maps, and I even listened to a little music now and then.

I strapped the Goal 0 on my pack and had the Droid on my holster, which worked like a charm. In the AZ sun, even with full usage I was able to get 100% charge within about three hours anytime between 9am-6pm. Sunrise/Sunset wasn't nearly as strong, but it would keep up with my usage + a little extra. The one day it was over-cast, it kept up with my usage but took twice as long to reach a 100%.

My general settings were airplane mode (obviously with GPS still on), 1 minute timeout and auto brightness. Plus, I removed the live wall paper and any widgets, save for my power widgetoid. I left it on all night as I also used it as my backcountry alarm clock. So by the morning, I would be hovering around 92% (between my evening usage and 1-2% drain of the evening).
