Ok, more noticeable improvements in 2.1. Somethings I hadn't noticed earlier: Significant improvement in the camera's 'Twilight' setting. Although still not as sensitive as I'd like it to be... way better than 1.6 which almost had no difference between 'Auto' and 'Twilight'. Unlike with Donut, the Twilight Setting now actually does something significant. Shutter speed slows down, so moving subjects will be blurred. But there is a big jump in exposure.

There also seems to be a very significant change in power management. Although I still need Juice Defender to manage my 3G/HSPA settings, I can now leave wifi, gps and bluetooth on all day and still get the same battery life I did with them all off in 1.6. HSPA and PUSH services though still eat up a lot and can kill your phone in under a day. Juice Defender handles mobile data quite nicely and can give you 2-3 days of average use.

GPS can also be left on since the chip only seems to draw power when an app needs it.
Currently, with the exception of my 3G services which are scheduled every 15min by Juice Defender, I have all my background data services and all radios on all day. By the end of the day, I still have over 50% power. It's not a marathon battery life, but the fact that I can leave all the features of my phone on now and it'll still last a day is a significant improvement in how I can now use my phone.

I decided to try just switching off mobile data and wifi for a couple of days. All other settings are the same. No Task Killer, no CPU underclocking, and no power management. After 33 hours straight... I still have 50% battery left.
