Here is an excerpt from a previous post in a similar thread. Although now I am running the PR1.3 and the v46 kernel. All other details are the same more of less and I am giving you today's usage.
My setup:
Overclock 500-1000 on ULV. on V40 Kernel. (now v46)
GSM only when not using internet or when accessing internet via wifi.
Battery Indexing Disabled using Tracker-cfg.
Battery is original that I have had since early march.
(I now have swappolube setting loaded also)
Today's use was around 25 sms and 30 minutes calling. Some photos using fcamera, about 80 minutes of Angry Birds. Some internet browsing approx 1 hour (wifi) and the updating of weather and email over wifi or 3G once every hour or so. Around an hour of listening to music. Some Jabber text chat via skype and facebook maybe for 40 minutes over 3G.
Full charge when I left the house at 0730 and I currently have 79% remaining.
Now that is not bad at all. That usage will get me about three days or so before I have to recharge.
1. Li-ion batteries age whether you use them or not. At 3 years old from manufacture, they have roughly half their capacity before further subtracting more life due to cycling (which they don't like either), and any N900 or smart phone battery will see LOTS of cycling! My laptop's battery is experiencing this right now as it appears to be approaching 3 years old. Bottom line: if you buy a new battery, try to find out the actual manufacture date of the cell inside.
That can be true but it depends on how the battery is stored. What you said is true if the battery is stored fully charged at 25°C, but if it was stored at 40% charge it will have 88% of original capacity after 3 years at 25°C, this capacity loss can be further reduced by storing at cooler temperatures. Read the Wikipedia article for some information on this.
I have nothing wrong with carrying an extra battery, I normally do anyway, I just hate using it cause I don't have a desktop charger, only like 8 bucks on eBay though - should get one.
Mugen battery is ridiculously sized and expensive, plus, the battery cover has some camera issues. As for high cap batteries from third parties, they're rarely even 1320 or 1350 as it is.

Nokia said their goal was one full day of heavy usage, so probably about 10 to 12 hours. As for the overall performance of the battery, it's sad. My friend can get twice as much use out of his EVO 4G than I can and he'll still have 50%ish battery left.
I used to keep Skype active but there's no point since I have to turn off my active T-Mobile connection if I'm not using it, else I'm screwed.
20mins = 15%
