Just had to share - I got my 9900 and have been unhappy with the battery life - I'm on call, get a bunch of emails, and use it to read RSS feeds as well. Battery had been lasting 12-14 hours. Turned Wifi on today after reading a post/thread about it somewhere. 15 hours later, including having to use it as a tether, and I'm still at 35%. Far from conclusive, but seems considerably better. I'll know for sure, but had to share. Thanks, all!
Lucky you. I'm at 1h40m used 3h20m idle and I'm at 21%. Just splendid...when it's idling it's fine but then when it's being used it goes through the battery so damn fast. I took my first one back because of this issue but its just the same. No idea what to do. I put .503 on and the other leaks before it but nothing works for making the battery last while being used. The battery life when idle did improve with .503 though.
Now at 19% after typing this and getting one bbm message.
