You could always try installing the Nokia Energy Profiler v1.2 to see where consumption arising from:http://www.forum.nokia.com/Technology_Topics/Appli
I did update to firmware 4 and I noticed the same with the aforementioned. After 10 hours or so the battery level drops significantly.
I restored contacts via nokia suite. Keep in mind that restoring via sd card always introduce serious problems when upgrading firmware (gps stops working, wifi halts,etc). For the same reason I am always biased to restore settings even from nokia suite. I restore only contacts, calendar and messages.
I did not installed any other software except nokia energy profiler and it showed the same amount of watts consumed as before(~0.02W - ~0.04W while locked and screen turned off).
Then I figured what was wrong.. Although the battery was dropped to 2 bars(1st day), it stayed to 2 bars for one & half days then dropped to 1 bar and stayed for one day more and all this while I was using the phone to make or receive calls.
So, clearly there is a bug in the "power level consumed figuring out algorithm".
I hope that helps..

I just want to add that this is a serious bug due to enormous psycological effects to the user.
If you dont know when to recharge is like a car with broken fuel gauge.
So, I assume that they will fix it shortly.
I only pitty myself that I have to do all the upgrade procedure from the start.
Other than that the firmware is ok. I hope not to introduce new bugs with the new firmware.
Get it right Nokia!
I also noticed the same problem. Before update I get 5-6 days battery life, now only 1-2.
I also tried to uninstall email client from apps, but batery life is same..
My E71 had a problem with Garmin. Garmin was running background process (in the options it was disabled!) and i turned it off again now it's everything back to normal or even better power consumption!
So try to find the background service with some processes listing program and you'll have the solution.

To resolve this problem follow the steps below;
1-) Delete files cardrunner.dll and cardrunner.rsc in your device, paths to the files in your device is as below.
2-) Then start Garmin application and go to “tools ->settings -> System” and disable the option "Launch Background service"
And that's it..

Noticed that too... on the 300 firmware nokia energy profiler showed constant energy consumption about 0,05W when not used.
Now just after the phone turns on the power consumption goes normally (http://www.image-share.com/image.php?img=133/168.p
I have no WLAN availability scanning (it's turned to 'never'), and I always turn the WLAN desktop scan off.
The funniest thing at all is that when I 'delete' the WLAN scan from desktop (in personalization options) the power consumption goes again as it was before using any WLAN connection (http://www.image-share.com/image.php?img=133/170.p
