thanks mate!

For a "real look", LOL... so you're saying we're all lying when we say our N900's are lasting us 1+ day's on a single battery charge...

Got my phone Tuesday, let it recharge for 12 hours, used the guide http://talk.maemo.org/showthread.php?t=35907
Didn't recharge it till last night... I can guarantee you they probably didn't use steps to help conserve battery life like, lowering the brightness, using shortcuts instead of widgets and changing email, weather, etc to update every hour instead of push.

I'm sure some people are having issues with the battery, but the majority of us who have posted about our use are loving it just how long it lasts.

Now that you mention it, isn't PUSH email actually quite effective in conserving battery life? No unnecessary connections are made.

Re: N900 Battery Test Results
 

out of curiosity just did a video test on my n900

height : 320
width : 608
data rate : 855kbps
total bitrate :983kpbs
frame rate : 23 frames/sec

audio : 128 kpbs
channels : 2 stereo
audio sample rate : 48khz

file size : 700mb
length : 1hr 39min

The above file I played in a loop(manually of course , no feature in n900 to play in loop :) ) for about 5hours continuous with wifi connected and on 3G network till i got the first low battery warning.

Had foreca weather widget running.
Emails via nokia messaging.
and sound through headphones.

hope that helps somebody benchmark their toy, if its better , it should bring you a big smile :)

IMHO i think the battery is just about OK, nothing exciting, but nothing to feel too bad about for the kind of device it is.

Re: N900 Battery Test Results
 

Whether necessary (because stuff is pushed) or unnecessary (nothing is pushed) a TCP connection is kept alive the whole time.

I can imagine this not allowing the device to go in deeper power saving modes.

I'd only put push mail on if it is necessary to have real-time e-mail. Else, I found a setting of check every 5 minutes instant enough to be usable.

Re: N900 Battery Test Results
 

maybe the battery problem is also caused by default settings of N900 - e.g. mine had automatic connection to wifi enabled. So the first night I had it home, it automatically connected to one of the configured wifi networks - and probably because of that until morning, more than half of the battery was depleted (or maybe because it was after the first/second rechargement?)...

And there are, in my opinion, more similar flaws - like the vibrator acting each time one touches screen - which could too decrease the battery life...

Now that I have my n900 configured a little, the battery indicator stayed unmoved for 10 hours of not using the device - and after a whole day of light usage (mp3 playing, for a few hours, reading sms, playing supertux for 20 mins, a few minutes of wifi), 2/3 of the battery is charged... Therefore I find the battery life about the same, maybe even better, as e.g. HTC Wizard I used previously..

As krk969 wrote - it is not breathtaking, but noone can seriously expect such powerful device to last a week on battery (only if in offline mode and left untouched).
