my first full day of use suggests that battery life is gonna be a problem for me. it’s 8:45p now, and i’ve got maybe 10% of my battery life left – that’s after leaving the house 13 hours ago (that’s when i remember unplugging my phone).

having said that, the phone is showing 14 hours 18 minutes of standby time (which might be right, since it’s about when i woke up this morning – very possible i started using it right away), and 6 hour 19 minutes of use, which i guess includes everything.

26 minutes on the phone, and about 6.3 MB of data received over EDGE and 1.1 MB sent.

we’ll see what happens in the days ahead (and how much longer the phone lasts now), but i think this may be a problem for me. today, like all mondays, was an active day – i didn’t get to sit much at my desk, and so was checking my mail a fair bit (and doing demos), but after about 4p, i found myself really watching the battery meter a lot and thinking that if i had been talking on the phone more or using the ipod more that it’d be even lower.

i have a couple of ideas on why it depleted so quickly – i have 2 e-mail accounts set to check every 15 minutes, and mostly stayed within WiFi range of the office all day (and i have it set up to auto-join WiFi networks that it recognizes).

i think the way the WiFi works is that it connects when it needs to (to check e-mail or something) and then disconnects after a period of inactivity – if WiFi drains significant power (and that’s my guess) then i may have effectively kept the WiFi power drain on for most of the day. i may move e-mail checks to every 30 minutes and change the brightness setting a little bit for tomorrow – that would reduce the load, i think.

anyway, we’ll see, but a little troubling for the first day. lots of other things i noticed – mostly i really like using it, and the pictures of my family on the main screen & when they call really brighten my day – they’re just shown in a vivid, fun way.

so hopefully i’ll be able to figure out a way to get the battery life more workable…
