I think this build has improved battery usage.
It's too soon to say but so far the battery usage graph is pretty horizontal.
Let's hope Sammy and Sprint did something about ICS battery.
Wow -- now that tFD10 0.1.0 settled in it def has the best battery life I have ever seen on this phone. If FD16 improves over FD10 -- all I can say is I can't WAIT to see what happens when you get a tweaked/themed tFD16 up.
Also, if I can put in a vote -- I'd love to see you do an odexed version of tFD16. I've been running deodexed ROMs forever; tFD10 was the first time in a long while I ran odexed for very long and I can't quit raving about it. (John Corleone -- you are _so_ right.) Deodexed is great too, but... I feel no need to change the theme on your ROM so for me deodexing doesn't do anything good for me. (NOT saying it doesn't do good for others.)

Not running full ROM but flashed FD16 modem last night... GPS locked instamatic for me, and indoors too. (Note I *never* got a lock indoors anywhere on GB modems.)
