Maintaining a TCP/IP connection drains the battery; so things like IM
accounts are the antithesis of long battery life. Some protocols are
also "thirstier" than others.

It's a shame, because one of the advantages of Maemo 5 is its design
to be always connected. Unfortunately, that isn't conducive to
multi-day battery life.

Some of the other power (limited QA, mainstream Linux userland, full
multitasking) also makes it very easy for software (including Nokia's)
to accidentally drain the battery by not being well written, not using
the heartbeat functionality and not stopping doing things when not in
the foreground.
