The reason the battery is so small is almost certainly not by choice from Nokia's side, it's just a problem of room in a device crammed full of other stuff. There's not much to go on there, so let's hope it'll not end in the fiasco known as htc tytn I (totally unusable in practice due to having to charge it every 3 hours).

I heard in one of the interviews (thinks its this one: http://www.maemo-guru.com/2009/09/vi...dr-ari-jaaksi/) it should last you through out a day, and they are working hard and doing progress on the power management now that they have a lot more testers and can customize the power management to actual use.

The n8x0 also steped it's processor, and the n900's processor goes up to 600 as opposed to the 400 of the n8x0.
Unless this new cpu is much more power efficient (so much more power efficient as to account for the 3g radio consumption) I find it hard to belive it will last through the day with moderate use.
Let's face it, it's not a device to say you will use it lightly. You'll carry the expensive brick the n900 is because you use it's many functions.
Actually it's the only turnoff I see for now. Everything else is a hacker's dream. Fast, lot's of hardware features, decent camera, enough storage and more open than android.

P.S. the comparation with the iphone is wrong imho because the Iphone doesn't have to push 800x480 pixels around and because it's not multitasking. n900 will most probably used with many apps open through the day.

Class, repeat after me, pushing notifications over the air is not multitasking

I think it will be fine for the avarge consumer user. Im also sure there must be power effeciency stuff made to both hardware and OS from n810. for the IT specialist there might be an expension battery pack from Nokia or Mugen.

I have the Mugen 3600mha battery for my n810 and use it for 3 days while never turning it to flight mode (online all day and night, home and at work).

I seriously doubt that the average consumer will buy this...

As a power user I always prefer the extra 20 grams and few mm's of width for a powerful battery and this is offered to the power users... well, I guess we'll have to wait and see

The thing is that the new processor will be better at "race to idle" - basically finish it's tasks faster and go to idle state, thereby saving power.

comparing the specs to my touch hd I'm also worried about this.

my phone has the same resolution but a slightly slower processor and does multitask. with heavy use I do get a full day out of it 2 days with little use but thats with a 1500 battery. saying that the n900 does have a slightly smaller screen so will just have to wait and see.

Do you think maemo 5 will have better power saving features than WM? I know that WM loves to try and save power I spent weeks batteling with the power saving features to get an app I'm creating to work.

I checked out the link, and reddit says it haven't got compass
however, the Swedish guy in the N900 walkthrough mantions that it has a digital compass ..

I think the battery life is not going to be good and the phone will be bashed in the main stream media for the abysmal battery life. I think that is one additional reason that this phone is just step 4 out of 5.

Anyway check this video. It starts at 8:45 am with 3 bars of battery and ends at 10:50 with just 1 bar.

Now we dont know how much the user used it in the 2.5 hours in between but definitely doesnt look good for the average consumer. Of course i will attach a battery holder to my keychain and carry the additional battery everywhere.

@sachin007 - did you notice in the thread for irreco for N900 one of the listed known issues was
'- BIG issue. Lirc daemon running background affects batterylife dramatically.'

So maybe not so bad afterall
