N900 battery life questions, issues, scenarios
 

I read through all kinds information about N900 today , even the pre-order website but unable to find out any specs talking about N900 talking hours , hours for video and web surfing . This is very normal information and Nokia did not ever mention in any place . Has anybody got information on this ?

It ought to be on this page but it isn't there yet. It's possible they haven't got the final firmware yet so there wouldn't be any firm idea about battery life yet:

Wait, does anybody really believe battery times as claimed by the manufacturer?

Re: N900 talking hours
 

Well it's virtually impossible to give an exact battery life anyway (battery life varies over the course of many charges, different apps use different amounts of battery, phone signals use a lot more battery when very far from a mast etc etc).

And even more in mobile devices where consumption can vary from practically nothing to a couple of watts and back again over the course of milliseconds.

this is from the data sheet

Already posted a couple of posts above.

N900 battery life
 

I apologize if this has been discussed already - I searched and did not find anything about this yet.

I was noticing that the battery on the n900, the BL-5J 1320mAh, appears to be a step down from the BP-4L battery in the n810, which has 1500mAh. My n810's battery was always dying, so I'm concerned about all day usage of the n900. I'm hoping that the n900 will use power more efficiently or something. I read that the new TI OMAP 3430 processor speed steps, so that could be an example of how a smaller batter can last longer...

Anyone have any thoughts on this?

Re: N900 battery life
 

My thoughts is to compare it against Iphone 3gs(i know) battery.
Since the 3gs is almost identically hardware wise it should give a good comparison. (http://www.reddit.com/r/technology/c..._side_by_side/)
The Iphone 3Gs has a battery with 1219 mAh, a little less than the n900.
I have read in mac forums about this and it seems alot of people manage at least 1 day with normal usage, and some even with high usage. So i hope the n900 with its higher resolution will have about the same battery life.

Just my thoughts.
