Yes, it is always running, THIS IS what a mobile phone is supposed to do presently, doesn't your iphone do it? what a shame..
Being constantly connected to Two sip providers? Hmm. Maybe you have quite high expectations. Actually i can drain my N900 battery in half an hour if I like to and say that my usage is normal. So Before jumping in conclusions please be specific what you mean. Stating here that this phone does this and that is not detaild enough. If you really want to be connected to all the stuff that N900 gives you option to be connected then IT DOES but battery will be emptied in couple of hours. Suprised? If so then you have not understood what you are holding in your hands.

You try to do it by 3G, the phone lasts 2/4 h. You install that magic widget, turn in 2G, and yeah, the battery is still poor but you're connected all the time, around 8 hours then (just being connected).
This was the situation ... before..
8 hours sounds about right. Pretty standard if you look what was sitsuation when N900 entered to market.

Yes you're right. But scientifically, I am comparing the overall feeling of the two devices.
You gotta be kidding me? Feeling? Iīm lolling here Who cares about that? We need data to make comparisons and to back our statements. Otherwise itīs just...yeah...feeling. Good luck with making reviews :P

BEFORE, the n900 had multi-task, permanent gtalk/skype connection, a browser really capable. The iphone had maps, much more speed, and vast amounts of software. Well, n900 won.

AFTER, here we have the iOS4. Guess what, the multi-task of the n900 is not so spectacular now, and they also start to be permanently connected. They still have maps (n900 hasn't, I'm too frustrated on this), a cam that works (forget the video mode if you are running the kernel ideal, at least in my case), and yes, the iphone has battery.
Yes. What is your point? That there is competition? Suprised?

BATTERY, because they do not need to disable the 3G, because they do not need to overclock the device and is still 2x or 3x faster than the n900 (iphone 3gs), and because they don't need to reflash the device each month, or to reboot each week, to re-gain speed and stability.
Whatta hell? Who says that you have to disable 3G? Who says that you have to overclock? Who says that you have to flash it? Or reboot? Have you installed stuff from devel/testing or some webpage? How did you measure iphone vs. n900 speed? What kind of different apps? What kind of cases with speed? What do you mean? I do not understand. Yes i could say that there might be speed difference on different task, but then again i could say that with fcron and shell i can do stuff in seconds that would take on iPhone different apps to manage to do them.

Itīs not so simple as you think it is when you are talking with different kind of people. Try to think out of your box.

Damn, each 5 minutes of navigation with 3G in the n900 is about a 10% of battery, and run afterwards to change again to 2G because you'll need the mobile in the afternoon. This stuff is inexistent in an iphone..
Sounds like HW problem.

What should I do. To disconnect from these services? To be always in 2G? To put the brightness to 1? To downclock the kernel?? Then why I've bough the n900, if everything has to be off..
Who has said that everything has to be off?

And well, after this experience with nokia, I'm really expecting that the next meego version will be too heavy for the n900. So I'm not going to have a better experience that what I already have now.
I have zero expectations because of current sitsuation and history of Nokia.

Having said that, I'm starting to thing that nokia has been always wanted to do a tablet rather than a mobile. So I'm truly anxious to see what they'll purpose eventually. But regarding the mobiles, I have serious doubts that my next 500€ will be given to nokia, again.

PD: To answer more precisely to you, what I say is, if nokia wanted to provide a device with these capabilities, they needed to be sure that his device could handle them in terms of velocity and of battery. The velocity of the n900 is too bad. The battery when you use these services is insufficient. So, I understand why the battery drains so fast. WHAT I don't understand is WHY nokia has sold this device and at that price if they didn't have any solution to this. It is just irresponsible.
I think that yous should make some kind of data/bug report that shows basically your usage case and how battery lasts. After we are able to reproduce it then we should compare to other phones and try to use them as N900 (eventhought it might be to some extent even impossible to use other devices as N900). Also ruling out fact that different operators might have different 3g/2g strenghts on area where devices are tested.
