o' boo f'n hoo. I paid 40k for my car and I have to spend time and money to give it gas. The more i use it the more gas i have to put in it. wasting time and money is part of life! charging is too. i'd love to hear someone chim in on the actual time it takes to fill the 900 battery and the cost in kilowatts in a daily basis. my guess its no more than 2 hours and 21 cents.

im wondering y people always complaining about n900's battery being drained fast, to think dat theyr surfing the net like hell..imagine ur using laptop with its own battery,do u think its battery will last up to 6-8hrs????

@kiss - bravo *clap clap* much better than my car analogy!

I just love the whole comparing the n900 to the iphone! A few days ago I had to fill in an application form, it pretty much asked for my life history. Now I'v used an iphone before and there is no way in hell I would have been able to fill out the form on one of those, the form was online so I had a browser open, another browser to check some information from another website, vnc open so I could check a document I had on another pc and while doing all of this I had some tunes playing in the background.

Hell just writing all the things I had to would have been painfull enough on the iphone lol

2 hours and 21 cents is not free

Either was your $500+ N900. If you can afford it, you can afford to charge it without complaining about it.

unless you also camped a few days on the line to buy it, 2 hours is still quite a significant cost

i never understood people "camping" out for a device or anything for that matter. good things come to those who wait. for instance, the first N900 buyers got buggy phones. I waited 6 weeks after launch and got lucky with a phone that has no "problems" that i can find.

So, test 1:

- Wifi disabled, 3G enabled, permanent internet connection, skype and gtalk accounts enabled, three times viewing mail, three times consulting a web page (less than 5 min browsing in total).
- A constant slope seen in BatteryGraph app.

-> From ~8:50 to 11:36, battery from full (~96%) to a 54%.

Other details, kernel overclocking at "ideal" conf, 2 desktops, widget of calendar, three contacts in desktop (saying if they are online or not with the green dot), two widgets-like indicating the internet IP and the battery percentage, brightness to the 3 position, display almost all the time disconnected. Mail autocheck each 30 min.

Well, this is a behaviour not surprising for me based on my past experience. However, perhaps being always connected with the two IM accounts makes a big difference.

Test 2 will be the same with the two IMs disabled.

(now, at 11:42, a 52%)

Another (improvised) test.
Unplug from dc at 12:00, both the iphone 3gs and the n900.

The iphone, with 3G activated. The n900, with offline (airplane) mode, cause I wanted to keep battery.

13:45, I take the iphone to search some web page. Before, I see the battery. Wow, a 97%, impressive.

14:00, I take the n900, I put it in online mode. Let's see the battery (starting from the typical 96%). Wow, a 89% (!), with airplane mode?

I really didn't expect such battery drain when the phone is just doing nothing at all. Or in the opposite, I didn't expect the iphone to be almost at the 100% with 3G (but no data connections) activated.

More tests ongoing.
