The best compromise so far is the E71 or even the E72. That phone can last easily 24 hours with heavy usage plus more!
Since the N900 hardware is somewhat similar to Iphone 3GS, I should hope it can at least match the iphones battery times.

Keep in mind the iPhone doesn't support true multi-tasking, rather serial tasking. So that'll change battery life comparasions despite similar hardware.

A personal comment not tied to the N900 only but to all this category of devices that are closer to "little computers that make phone calls" rather than "mobile phones that can also do other things".
Power management is always a top priority on any device not plugged to the wall constantly, but it's really critical in this category of mobile computers. Because of its form factor and legacy phone use cases your expectations are similar to the ones you have for average phones concentrating in a few bunch of use cases. But because the hardware and software features available in the device, you actually end up using them as much or more than your laptop at home.
Look at this, it's one of my days of intensive use of my lovely N900:
- Wake up in the morning. Checking email (personal and work) and a couple of sites.
- Commute to work streaming music through 3G-3.5G and bluetooth headset while checking more email and browsing more sites.
- Ah, forgot to tell that I might have turned on already my presence with Gtalk, Jabber and Skype. I have activated notifications of my location, so GPS/A-GPS ping occasionally as well.
- In the office the email daemons keep checking my mailboxes (even if I have them open in my laptop...) because I was too lazy to change the preferences and actually like the fact of keeping my recent email at sight when I'm in not so interesting meetings (I guess it happens in the best companies).
- But the primary use of the device while sitting at work is a Twitter/Qaiku notifier. I expect to get a display wake up every time the app finds out something new (quite often actually, and this is why I don't want to see this in my laptop screen).
- If I'm not listening music all the time from my device is mostly because I'm sharing office with others and doing it with headsets takes too much concentration away of my work and makes me feel like an autist inside a team. Otherwise...
- Back home, more music streaming, email and browsing.
- In the afternoon I'm with the kids. I try not to be a pathetic father hooked to his mobile device while the kids want to play with you or require your attention in the playground. Still, some pictures and videos occasionaly are taken, and uploaded right there.
After the kids go to sleep, more email and browsing, including some trivial videos here and there. I don't watch TV and I'm becoming more and more lazy opening my personal laptop in the evenings, since it reminds me the fact of having used the laptop at work for so many hours. Interestingly enough, it seems my brain doesn't bother by the fact that I have been carrying the mobile device even more hours... Perhaps it's because I don't need to open the lid and press the power button on (something that reminds me to "work", while tapping the N900 display brings me the idea of "fun" even if then I end up checking my @nokia.com email and maemo.org again.
:/ 
- And then at some point I go to sleep. But my device stays active (this time plugged) since then it's the time to become an independent culture peer, sharing files no "free market" is able to distribute efficiently to global citizens nowadays. In the morning it will wake me up, full of energy and with a green light.
Comparing all this to a regular mobile phone is interesting but actually... try to compare this to our full fledged laptop running on its battery alone. Good luck.
3 additional thoughts, common to all the devices in this busy category:
- Note that a single MyFunnyWidget downloaded from somewhere doing something stupid in your home screen can bring down the hard work of a big and skilled team. This is why having acknowledgeable distribution channels with QA processes in place is not only useful but necessary. The user will think "this battery sucks!" and will complain in forums, microblogs and care support lines before thinking that the innocent app downloaded last week is causing that. Or 2-3 buggy apps in conjunction, even worst.
- If I would have the money or the power to convince someone with money, I would go for the production and promotion of beautiful and useful stands to have your device in your workplace, with the right inclination, music speakers, and a dock of all kinds of extensions (full keyboard, switcher to my dedicated computer screen, etc). These would be the selling points but the killer feature would be actually an integrated power plug recharging my battery while being at work. This would mean automatically: zero concerns about battery life between Monday and Friday while using the device more and for more things.
- Another good investment will be the design of better "Outdoor" profiles. Currently they are mostly about making your phone louder so you can hear it in the main street or while having it inside a bag at the beach. But what about "Outdoor" meaning also "I won't get a plug to charge in hours, probably the whole weekend" and applying automatically the most drastic power management policies: scarce pings to email, presence, wlan, GPS or actually no pings at all unless manually required by the user and plenty more compromises you can make with daemons, Mhz, fps, wakeups, etc (bare with my technical references, I'm not expert in the matter).
But you are reading all this also waiting that I say something specific about the N900. Alright.
Well, compared to the competitions usually Nokia performs quite well with power management and the Maemo team has actually a good track (imo at least) with previous products. Anything you are lucky to see before sales start is a useful reference but that's it. Power management is about fine tuning 1001 things and is something every competent team keeps improving until sales start and beyond.

Are you saying that you can do all this in a day and never plug it until you go to bed?
Or is it all hypothetical?

Sounds like a great day, qgil ;D
Btw, you don't charge the N900 at all during the day with all those online activities? Especially in the office, where you are oh-so-close to many USB ports and power sources..

I got me two of those: USB charger, powered with 3 AA batteries (one for use, one for hacking).
They are incredibly useful. If i know my cellphone or tablet won't last through a long day, all i have to do is to bring that little box with me, and perhaps some replacement AA's if i need more than a day of battery life.

I use a MintyBoost for most things and that's just 2 battery one. Slow to charge but highly efficient.

All times are GMT. The time now is 19:20.
Mugen will make its usual range of extended batterys like before, if you really want longevity and dont the mind the extra bulk and weight, the Mugens are among the best.
