Initial battery test of pre-production Nokia N900

I want to start this post by making sure you all understand that the Nokia N900 I am testing is a pre-production model and now that we have word the N900 is delayed as Nokia refines the software many things that I am having issues with may be resolved and not even present on shipping N900 devices. I imagine that one are where many optimizations will occur is in battery life and efficient resource management. Given this disclaimer, here are some initial battery life figures to consider.

I have not yet run a test of video or music playing constantly and will try to do so over the next week. I conducted this first battery test with real life usage, which is how I use my device. I had the following up and running when I started with a full charged battery: Maaku with two Twitter accounts being updated every 5 minutes Push email with Mail for Exchange IMAP email with 2 accounts updating every 15 minutes 45 minutes of active web surfing, Mauku usage, and general device navigation (on the train) Active and updating home screen widgets (AP News, Facebook, Mauku) Connected via T-Mobile 3G and EDGE with WiFi and Bluetooth turned off At 4 and a half hours I received the battery low warning. The battery ran out after for 4 hours, 45 minutes and the device shut down. After realizing Maaku was updating every 5 minutes, I went in and changed this to 30 minutes for automatic updating (you can always manually update). I will conduct more tests, but wanted to give you a feel for how things are going so far.
