Just to add my lumia with heavy usage but with wifi off and 3G on plus email sync every hour I get a day plus a couple of hours before it dies, I actually had two days and four hours with one charge with very light usage, but I do tend to switch the phone off when I got to work on the underground as it constantly searches for signal which I find drains the battery.
I purchased my Lumia 800 on Dec 12th launch day for HK. Like many I also have battery issues with my phone and the firmware update did little to nothing to improve it. I synced my hotmail, gmail, exchange, and weather app. With this setup, I only get ~6 hours with 30-45 minutes of talking and 1 hour of web browsing.
HW Revision #112.1402.2.4
Full Charge Capacity970mAH
I went to 4 different stores. Each Lumia 800 I tested was in black with both the old and new firmwares. However, the HW revision #s all ended with a 4.Unsurprisingly, they all had a capacity of 970-980mAH.
However, at the flagship Nokia store in Causeway Bay, there was a Nokia Black Lumia 800 on display with a revision that ended in 3, and it had a full charge capacity of 5100 mAH.
Based on my findings it seems like its true that HW revision # ending in 4 has battery life issues or either that the entire batch of Lumia 800s in Hong Kong is bad.

This from 18 minutes ago...........
Nokia has released a statement acknowledging that they are aware of the power consumption issues plaguing early Lumia 800 handsets and are working towards fixing the problem in the near future.
According to Nokia, customers have reported that the devices pre-loaded diagnostics tool on some Lumia 800 handsets shows a lower battery capacity than expected. Upon those reports, Nokia began investigating the issues immediately and determined that the battery itself is fine. They came to the conclusion that it is in fact a software problem that can be solved easily and that their other Windows Phone handset, the Lumia 710, isn’t
experiencing any of the same issues.
A software fix is expected to arrive in early 2012. However, for those who don’t want to wait for a fix to come via a software update, Nokia can arrange to give you a replacement phone. If you currently own a Lumia 800 then there is a way to determine if your device is suffering from this issue. To check and see if your handset is one of the affected ones, first dial ##634# then accept the disclaimer. After that, select battery status from the list of options. That will then show you the batteries capacity. If the full charge capacity is anything less than 1000mAh, then it is affected by this problem.
New production models of the Lumia 800 are shipping problem-free according to Nokia. However, in the event that any of these issues arise on one of the newer production models then they recommend you contact their customer care for additional support.

Exactly. Despite the fact that my full charge capacity is around 1500 mAH, the charged amount never exceeds 65553%, and this is the same for many others. Does anyone knows if this is a known issue and that Nokia is aware of that???

I have a Lumia as my brother has one too.
But we have quite different battery life results.
So I have Lumia with Simyo (EPLUS carrier)
He has Lumia with TMob Germany
When I activate 3G the network indicator shows "H" (HSDPA according to Windows Phone manual)
I get a consumption of about 170 mA according to Diagnostics Tools!
When he activateds 3G the network indicator shows "3G" (no "H")
He has a consumption of about 300 -500 mA according to Diagnostics Tools!
When we deactivate 3G we both get around 150 mA
When I exchange the sim card with my brother I get high drainage (with "3G") and he goes down below 200 mA (with "H").
So I think this is definitely 3G AND provider related.
So where is the reason? One could be that TMob uses an more expensive HSDPA mode up to 14, 4 Mbit/s (profile 10) while EPLUS only supports up to 3,6 Mbit/s.
Hi, just thought i'd post an update.
I received my replacement phone, from a different batch as I requested specifically, yesterday.
Off of it's 50% charge it lasted 6 hours of heavy use, setting up, emails, 3G, downloading several applications, playing Fruit Ninja, texting, calling, FaceBook, Twitter, internet browsing and Wi-Fi.
6 hours is what original Lumia 800 managed with average use.
Today I charged it from dead too 100% and started using it it moderately to heavily, it lasted 15 hours.
My original Lumia 800 managed 16 in flight mode.
So yes, i'd say it's a batch issue.
Go to your provider or original place of purchase and request a replacement Lumia 800 from a different batch on the grounds that it is not suitable for purchase.
