After installing OS X.2.5, my estimated time remaining on a full charge (with InDesign, Safari and Mail open) had increased from around 2:55 to 3:19.

After opening Photoshop, it dipped slightly, but quickly regained its original estimation after the initial processor strain.

Can anyone else verify this?
Am I crazy to think that a minor upgrade could add between 20-30 minuted of battery life?

mdc · Apr 10, 2003, 03:35 PM

is this possible? i am on an iBook and i unplugged the charge and my time is around 20 minutes more than i normally have.

hmmmm.

djjava · Apr 10, 2003, 03:46 PM

maybe by 10.3 we'll get the 4.5 hours that was originally guestimated.

jtbowden · Apr 10, 2003, 03:46 PM

I have a 17" and it stayed exactly the same (2:01). We'll see what happens...

lazydesert · Apr 10, 2003, 03:48 PM

Just unplugged my 12" and it said 5:18, but as soon as I started posting this it dipped down to 3:46.
The ladder is still more than what it had said in 10.2.4

morlium · Apr 10, 2003, 03:49 PM

wow. 5:18!?!?

that's a crazy estimate, even for a moment.

maybe those who can rihgt now, recalibrate the battery with the update before posting estimated remaining battery life times....

nobitacu · Apr 10, 2003, 04:05 PM

wow, you're right! my battery life from full charge jumped from 2:01 to 2:25 after update! hehehehehehe!

2:14 before update with only software update running (and done updating) airport, BT etc. off, screen at 1 brightness. right now, Safari and Proteus on, brightness at 4, Airport on. estimated battery life is 3:28

edit: havent plugged it back in, i'll probably just calibrate it again. wont hurt.

tritonus · Apr 10, 2003, 04:48 PM

After 10.2.5:
2:57 remaining
BT off, AirPort on (browsing)
Safari, Mail and Toast open
Display brightness full (auto-sensing)
dropped to 2:40 after 2 minutes of use

dettociao · Apr 10, 2003, 04:49 PM

Now burning a CD with Toast

Yea, I'm going to re-calibrate it and see if it'll improve it even more.

tell us how to recalibrate again please

Plug it in; charge it to 100%; unplug it; and let it run until it's out of juice. Then charge it again.

nobitacu · Apr 10, 2003, 06:33 PM

You beat me to it!

Oh, and for some people who may not fully understand this - when its out of juice the PowerBook will go to sleep automatically.

BTW, earlier today under 10.2.4 I was got about 2:59, and now with 10.2.5 and the same settings, it says 3:35!

Time to recalibrate again, and see what happens... I guess the fastest way is to open up Medal of Honor.

djjava · Apr 10, 2003, 07:02 PM

With Airport on, No bluetooth, and Entourage open in 10.2.4 : 2:30

With Airport on, No bluetooth, Camino and Entourage open, 96% full, in 10.2.5 : 3:30

AssassyN · Apr 10, 2003, 07:24 PM

Wow!

Impressive to say the least! I'm a bit weary, however, about updating to 10.2.5 b/c those who jumped right on 10.2.4 suffered some issues like a funked up clock and such...anyone experiencing any backlashes of installing 10.2.5?

nobitacu · Apr 10, 2003, 07:34 PM

No problems here at all, only improvments. ^_^

Ming

djjava · Apr 10, 2003, 07:40 PM

just finished charging the battery... it went from 3:30 left, to about 2:30.. whatdaheck??? i'll have to calibrate and see what happens.

also, anyone else experience a bit a of a slow down after the update? i have yet to reboot, but maybe i need to sleep the machen and let it rest... it's had a ruff day.

SummitWynds · Apr 10, 2003, 08:25 PM

Wow, I have 3:58 on the 17 inch. I also went from 1 bar (barely) on the Airport to 3 bars.

nobitacu · Apr 11, 2003, 12:45 AM

WTF! After re-calibrating it, it went back down to 2:05 min! Same type of usage as before. Now I'm mad! I'm going to re-calibrate once again and see if that'll change anything...

parsec_kadets · Apr 11, 2003, 01:00 AM

Has anyone actually timed how long their computer lasts before the battery runs out before and after the update? It's cool that OS X SAYS it will last longer, but does it really? That time calculation has been known to not be 100% accurate (I'd be impressed if it was). Is there REALLY been an improvement in battery time?

i was recailbarting last night and noticed that it took a bit longer for it to drain the betery than it had said. So maybe when i go home later it will read better. We'll see.

nobitacu · Apr 11, 2003, 12:54 PM

Nice, i recalibrate it again, and now it's even better! 2:42 min same setting. Good, it got better now hehehe. I'll keep it this way.

Jacket · Apr 11, 2003, 01:30 PM

i recalibrated my battery last night, i had to let it recharge overnight while turned off, but i'm hoping the battery life will be greatly improved when i come home to use it after work tonight.

Yea, that's what I did too. The first time however, i didn't let it recharge while it's turned off, or sleep mode since the computer don't really shut down. I started using it while it was at around 70% charged. Bad mistake for me since when it's full, it only showed 2:05 min left on full charge, which was worst. So I did it over again and this time to just let it sit and not use it at all until it's fully charged, I did this overnight. Now it is back to almost 3 hours of battery life, so I'm happy now.
