TiBook, 10.2.5 and battery life still ridiculous
Dale Glaser
Looks like 10.2.5 didn't fix the TiBook battery problem.
My battery got about 1.5 hours charge on it, and then I upgraded to
10.2.4 and found battery charge reduced to 20 minutes.
THEN I found that this was a problem that people hoped would get fixed
with the next system update.
But no go.
Does anybody have any more information on what the options are. I
thought I read that if I replace my battery the problem is fixed, but I
don't want to do that and ruin another battery.

What's on with your TiBook? My GHz TiBook gets 3.5-4 hrs per charge, and
my wife's 867 TiBook does about the same or a bit better.

Definitely a major improvement for me - at least back to pre 10.2.4
behavior - and I think even better than ever. OS X now reports - and
*delivers* - longer battery life than 9.2.2

Odd. It did here, to a limited extent at least. I'm on an iBook, and
x-charge showed I get about 25 minutes between charges on 10.2.4 and 70
minutes on 10.2.5
I *did* have to power cycle it a couple of times before it got more life
(each time it sank to 0% and then stayed there for a long time; net time
around the life was longer by about the amount of time it had spent at
0%). Have you done that? Just leave it on and running (powersave
disabled) until it falls asleep because of low battery.
I have noticed that even at the end of my 70 minutes battery life,
x-charge shows a 30% capacity which immediately drops to 0% and the
'book goes to sleep without a low battery warning. So it looks like
there are still bugs, just *different* ones.

That's about what happened to me (I'm sure it was more like 2.5 but
memory plays tricks).

So did I.

I was initially pleased, then annoyed.

I don't *think* it ruins the newer batteries. Leastways, I 'borrowed' a
newer battery from a client's iBook and it was fine, but I didn't leave
it in there for long.
All of our clients with 'older' iBooks (pre 2003) are running OS9. The
only clients who are running 10.2.4 are using newer (ie this year)
iBooks, and they haven't had problems, which implies that there is
something different about either the battery or the power manager that
doesn't trigger this bug. And considering that the newer batteries are
different (eg compare AppleStore specs on 'crystal white' vs 'opaque
white' iBook batteries) then replacing the battery is probably very
likely to solve the problem.

Some iBooks/TiBooks didn't suffer this problem, others did. It appears
to be age related (though not "number of charge cycles of the battery"
related). I suspect some change was made in newer batteries, and the
power management in 10.2.4 wasn't tested with batteries produced before
this change.
