I did some very rough testing of the FreeRunner battery life today;
keep checking planet.openmoko.org for a more fleshed out report
sometime in the week, but here's some numbers so far. My FreeRunner
has been almost always on since I received it, so this was one of the
few times that the battery has died due to lack of charge, and
certainly one of the few days that I haven't plugged it into my laptop
so I could play around with it.
The test methodology:
I've got two FreeRunners that were left to charge fully overnight and
for a morning. At midday I unplugged them both and set the power
management mode to "dim only, don't lock". Despite how this may sound,
it does lock the screen, but doesn't put the phone into any sort of
standby mode. It seems full powered, but with a dimmed screen.
One phone remained on my desk for the day, the other came with me
whilst I enjoyed the bank holiday break from work.
During the course of the day I had the GSM modem powered at all times
and the wifi running for a good couple of hours, although it rarely
did much apart from iwlist eth0 scan. I sent and received a couple of
text messages and received a very short phone call. I watched whilst
my girlfriend tried to use the dialler and contact apps for what felt
like an age, but probably wasn't very long. I also posed with it in
front of some folks with iPhones in a coffee shop; the poor fools
didn't seem to realise the nerd spectacle they were being treated to,
however.
The battery died just before 8 in the evening. The phone that was on
my desk lasted less than an hour longer although did (if memory serves
correctly) have wifi turned on all day.
I'll continue to take unscientific measurements during the week and
craft some sort of blog post of it.
