listen to you guys....:o :rolleyes: 3 hours and still ticking....2+ hours, FOUR hours!!!! I have the 15" powerbook firewire 800 and am lucky to get an hour 45! :( I REALLY hope that this improves the life of my battery....will let you know later....


edit: well, it's later now and am SUPER thrilled to report that it looks like the battery has more than DOUBLED its life. I always look at the percentage (and compare to the 'time' the menubar gives me) and it's now draining NEARLY as quickly. Hallelujah! woo-hoo! - That translates into 3.5 hours! Go Apple!

This was overdue. Panther did something to my battery life that I didn't approve.

Last Friday my PowerBook lasted for about 3 hours and 45 minutes on the plane with processor at automatic, screen at 2/3 brightness, Word, iCal, and Webster's dictionary open and backlit keyboard at full. If this makes it last for longer, I am afraid I'll never use that extra battery I ordered with my PowerBook. :)

an hour 45? yikes. :eek: what are your options like? AE? BT? screen brightness? processor speed? apps running?

I get ~3.5 hours with my rev. B 12" PB. Depends on usage and screen brightness though... could be under 3 or up to 4.

I hope this update is like firmware update 1.3 was for the original ipods. Oh man did that change battery life... :D

Xbattery shows me with a full 4.4Ah

same here.
Just installed it. I get average use of 2:30hours on my new pb12" that's with automatic and full screen running lots of apps, safari, itunes, mail..etc.

I hope this makes it even longer! It's at 90% charging but still says 2 more hours to charge! :) how do they do that!?!?!?

Can't have come at a better time for me. Going on 2 plane rides all day in 2 days!

Will post after!

This may just be a spell mistake by Apple, but in the german version of the update there are 3 PowerBooks 12":
PowerBook 12"
PowerBook 12" (DVI)
PowerBook 12" (FW 800)
Just a mistake or is it like with G5's appearing at Apple Store 3 days before launch?

I really hope this helps my iBook Dual USB!

I get an amazing 17 minutes or so of battery life! Reduced speed, brightness as far done as possible, Airport on and using.

My PowerBook G4 500MHz gets about 3 or something 3:30 or so with brightness down all the way, reduced speed, Airport on etc.

McMike
Dec 17, 2003, 04:09 PM
I maybe wrong but I think there was also the 15" in the german version noticed separately! I've just updated so I can't access the info any more... Maybe someone else with a german OS can confirm this!

That 0% probobly refers to something like 0.1...% that needs to be charged after the update was done and the extra capacity discovered. Give it a minute or two and you should be ok. Otherwise, goodluck :)

I've had my PB 15 1.25GHz plugged in all morning here at work, so the battery was full, but after that update it tells me "0:51 until full".

? (!)

This thing's gonna suck down another HOUR of juice?? Suhhhhhhweet!

As it is I forgot to condition the battery when I first got it (DOH!) so have only been seeing about 2 hour battery life. Hopefully this will improve that.

I wonder which iBook i have. Its a May-2002 12"-model with CD-ROM, 600 MHz G3 and 16 MB VRAM, but NOT opaque.

It still has Apple Garamond font for "iBook" and the "classic Dual-USB-Look".

Anytime the battery in my late 2002 ibook 800 starts acting wonky they come out with some sort of update. The other day I swear to god it said I had 7 hours left. Usually I have about 5.

I've always wondered how exactly these work. Do they somehow make your laptop use less energy, or do they make your battery be able to store more juice? If they effect the battery, how?

Also, I've never owned a laptop, but am more and more wanting one. Got to the point where I copmmletely filled out an order for a powerbook, but I'm still probably going to wait until I go to grad school. I'm wondering if these battery times, 2 hours, 4 hours, are normal. Maybe it's just because I'm inexperienced, but that seems horrible.

iChan

Nope. Powerbook just put itself to sleep. And I didn't bring my charger because, well, it was fully charged! Will just wait until I get home, I guess.

Apple gave me a bum battery to begin with. I have never gotten over 1:30, and now it's down to about 45 minutes tops.

I called them up, and some lying representative told me that the 4 hour benchmark they give you is for when the computer's asleep. I was so pissed that anyone at apple would say that that i just hung up. He said i was doing well if i was getting 45 minutes with the computer on and running. I couldn't ******** believe it.

Don't quote me on this, but I think the update affects the battery. It must affect some chip in the battery or something. If it affected the laptop using power, I think it would have been included in an OS update (10.3.x). Also, this update is good for Jaguar and Panther, so it's independant of the OS, making me think it affects the battery.

That and the update says "Note: Once the Battery Update software has been installed, each battery you install in your PowerBook or iBook will be updated automatically."

So it's updating the battery, but not really making it store more juice, just making it communicate with the computer better.

any suggestions for best battery life from people who have spent time to find out?

Well, heres a interesting fact.

12" PB DVI, 100% battery and my charger was showing green (charged yah). Installed and rebooted....just as it got into OSX i unplugged it and moved downstairs....to see my battery indicator showing 78%...

Maybe they've realised they can get more out of the Al batteries.

Dec 17, 2003, 04:39 PM
I got two batteries with my Al-Book 15" 1.25, and they're both due a charge now, so it'll be interesting to see how different it is. I can't really say I've had much of a problem so far - nothing like 4.5 hours as quoted, but more like just under 3, and isn't really affected by what I'm running / doing, remarkably.

Both batteries seem the same in terms of charging time / charge life and I'm glad about that.


This is my first Mac after almost 7 years of PC. Had a lot of problems with charging batteries in a PC laptop, so it's great to have something reliable from a manufacturer that are interested in their customers' views, and update stuff whenever needed. I'm very happy with it! Consider me switched!

45 mins is abnormally short. Call apple back.

on a PB 12" rev a, i started with (from cold start>running update>restart, about 3 minutes) 2:02 left with 88% charge. after the update it listed initially 1:32 left, but now has climbed as high as 3:25 (i've done nothing except launch mail, energy saver {longest bat. life setting, low processor use} and wake up the screen about 3 times.)

It's up to 3:48 now, and i think the longest run i've ever gotten out of the battery was about 4 hours.

Looks like it leveled off, 3:41 with 86% charge. mind you, i've always thought the time left was more of a guestimate than a real countdown timer.

I've left my pb asleep for 24 hours before and still had about 50% charge, so thats just wrong. call apple and complain. they should send you a new battery...provided its still under warrenty.

You restarted the computer, that takes battery too, and a heck of a lot of hard drive spinning at that too.

Just chatting with a friend of mine. He has a 15" AlBook. He had a nearly full battery, ran the update and restarted. As soon as it started up, it went to sleep, he had to plug it in to wake it up. The update completely drained his battery, it said 2%. Just asked him to check the LED's on the battery, indicator is only flashing one light, and hes upto 14% now.

Glad I'm using a TiBook :)

Dec 17, 2003, 04:59 PM
the PB fell asleep, upon awakening, it was reading 6:05 left (Yay!)...then fell to 2:21 (boo.) Looks like its going to settle again at about 3:30 or so at 80%.

One thing i noticed, when i shut it down Monday night, it was at full charge. wasn't turned on until today (and after the update..about 5 minutes of on time) it read 88%. I'm wondering if the batteries haven't been charging up fully, and thats why the update was released.

either that or my battery has leached out 10% of its power in about 36 hours.

holy MAC!
Dec 17, 2003, 05:00 PM
something interesting just happened.

i ran the update, rebooted.

i had a full battery before

after reboot: 77%

so i was happy (OH MY GOD< MORE BATTERY LIFE>>>> HURRAYYY)

then, after charging for 15 minutes, it suddenly popped to 100%......

but now,

old time: 2:12
new time: 3:12

That's an hour's gain.

i just want to say the following:

10.2.7(1:45 hours) -> 10.2.8 (2:12 hours) -> panther updated ( 3:12 hours)

Yes I'm the same, lucky if I can get even near 2 hours under normal use - nothing fancy ... it's hard to believe others with the same machine could be getting over 3 hours!

My PB was plugged in, fully charged green light was on, either 99% or 100% not sure, installed the update and restarted the light on the charger turned amber, and the battery was charging said it had 1:11 or something till fully charge, and it was on 88%!

what I think is the batteries don't charge to the fullest, and this update allows them to use their maximum capacity. I'm not an expert though.

THANKS

I wrote a lil while ago thta I had restarted with the new update with around 99% battery and 2:17 min left on it. after the reboot it had 1:47 left. Now I am sitting about 10-15 min later with 63% battery and 2:11 min remaining (however it is ticking off a min every 30 seconds) who knows wtf is goin on. I have yet to be impressed with any batterylife in a powerbook. While it is i'm sure a huge accomplishment to get it to 2 hours, if Jobs wants the market to move to notebooks like he has said, that number needs to be boosted up to around 6-10 hours... will it ever happen? yes. soon? doubt it.....:(

Longey Nowze
Dec 17, 2003, 05:10 PM
try re-calibrating your batteries, if that doesn't improve anything check your energy saver pref, try letting the HD spin down, maybe the CPU isn't set on Auto?

hope this helps

I updated my 15 AL 1.25 PB with a 50% batt life. Like the rest of you after restart it went to 0% with a warning about running on reserve power. I plugged it in to charge and it now says 22% with 6:27 until full. Sorry to be stupid here, but what does that mean? 6 hours 27 minutes until full or I have 6 hours 27 minute capacity (i wish) or 6 minutes and 27 seconds until charged, what does that mean?

laodamas
Dec 17, 2003, 05:27 PM
IIRC that the battery updates work by changing configuration data that is stored on a memory chip (EEPROM?) inside the battery. This update most likely forces a battery recalibration followed by changing the configuration of the APM, the circuitry that determines how much battery the system has left, the source of power, etc.

This update might benifit from the following:

TIL 58616
" To ensure the indication of remaining battery life is as accurate as possible, the battery should be fully discharged in your computer and then fully recharged. Simply use the PowerBook without the AC power connected until it shuts itself down, then plug in AC power and recharge the battery"

try a short charge and unplug, repeat a few times. make sure you are getting the battery reset. in fact, try running the battery to dead and recharging before you get real excited.

right now, after some playing around, i am getting 45 minutes more than pre-update by the meter....

After I restarted I had 2hrs on a full charge let it sit while I did a little bit of web browsing and got 4hrs when I checked later.

ariza910
Dec 17, 2003, 06:04 PM
For all of you complaining about battery life below 2hrs that is probably due to the fact that you have the power setting to max CPU and HD.

change the settings a little and dim the screen a few notches, you should be able to get above 3hrs.

I have an Al powerbook and get 1hr30min at max CPU and about 3hrs by making some adjustments.

And please stop posting "after the battery update my meter says 50% and before it said 75% I lost battery life blah blah blah"

The only way to really tell if it made a difference is if you timed the battery from full charge to empty and then timed it again from full to empty after the update under the same use conditions. I doubt anyone has done this.

The battery % or Time bar are just an estimate and hardly scientific or accurate

applemacdude
Dec 17, 2003, 06:09 PM
OK PEOPLE Calibrate your battery by letting the battery drain completely without using the computer. Let it charge back up 'till its down. Maybe this will help

After running in a fairly low-drain situation (BT/wireless off, reduced cpu) for 70 minutes, my 15" Al powerbook is at 71%. At that rate, it shoud be good for a solid 4 hours. The battery icon seems to think that there is another 3 hours of life left in the batter. While it is a little better than before the update, it doesn't feel like much of a drastic improvement. All in all, I'm appreciative of the extra 30 minutes of time. Thanks Apple!

Dec 17, 2003, 06:15 PM
calibrate: use the machine till it dies out from under you. literally shuts down from lack of power. plug it back in and charge it back up!

and FWIW, i always use highest CPU, and have 3 to 3 1/2 hours easy. i also do the above once a month. go figure.

Bob Knob
Dec 17, 2003, 06:18 PM
For all those posting that you have less battery time after the update might want to stop and think about what this update does.
It resets and re-calibrates your computer and your battery to more accurately determine the battery's charged state. When your battery is being charged the charge cycle will stop when the battery reports a full charge. If it falsely reports full when it's not then you get a shorter use time. Because the last time your battery was charged/cycled was before the update it's likely your battery wasn't really fully charged, even though the system thought it was. Now that you are using the new software you are seeing just how much of a difference there was. Until you have had time to cycle a battery there is no way you can tell if this update has had any impact at all.

FYI, I have been using this update since Monday on a test iBook and it gained roughly 40 minutes (average) of life between charges. I didn't really see any difference the first time it was charged, but the next charge was like having a new battery again.
(I didn't just break an NDA saying installed on Monday, and no, I did not get it illegally)

I've done calculations, and letting my 800 FW 15" Powerbook sleep for 24 hours only used 12% of the battery. However, I must echo that the battery life is unusually short. I get like 2 hours out of the battery. Yay!

paulie
Dec 17, 2003, 06:19 PM
I'd been worried about erratic battery performance on my Rev A 12" PB.

So far, I've been able to cycle the battery (partway to empty, empty to full, draining again now) and I'm getting about 25% longer life out of a 10-month old battery.

In my "travel mode" (dim screen, airport extreme off, bluetooth off, reduced processor), I am now seeing a report of 5 hours of battery life, something I've never seen out of my little PB.

If the PB even lasts the 4 hours my iBook lasted, I'll be more than happy.

Up until this update, I never saw more than 3 hours out of the battery.

I think that the Energy Saver tab is terrible. I cannot tell the differences between the modes. For example, I'm not sure that the only difference between 'dvd playback' and 'highest performance' is just in the screen/sleep times. Ditto presentations. Does automatic adjusts your CPU performance automatically? If not, what's the actual difference with Highest performance? I think that there's more going on under the hood than what the configurator suggests.

I think re-calibrating might be a good thing.
ALSO TO ADD: I would charge back up (after draining it by using it) WITHOUT using it at the same time. That wrecked one of my batteries before. So, drain it, and just plug it back in with lid closed.

I have a 12" rev. B.
Was: 2:30 on high and bright scree, airport and average of 5 applications running.

NOW: 3hours

Dimming the screen a bit really saves battery life, so does turning the airport off.

The above timings are using AUTOMATIC setting and running airport, full screen light and running Safari, Mail, iChat, MSN, Yahoo, ICQ, Virus things, podquest, weather drop, Remote Desktop, isync, Norton AntiVirus.

The only way to really tell if it made a difference is if you timed the battery from full charge to empty and then timed it again from full to empty after the update under the same use conditions. I doubt anyone has done this.

The battery % or Time bar are just an estimate and hardly scientific or accurate [/B]

Huh, that's funny. I thought by having a full charge, running the update, then having it say 0% and shutting down I could tell that I had lost battery life, but I guess you're the expert!

I don't know why I only get 20 minutes of battery life on my 17" AlBook. All I was doing was burning a DVD while backing up with carbon copy cloner to a firewire powered portable hard drive, charging my ipod, playing iTunes with the visualizer on large in the background, while running some photoshop filters on 5 GB files and doing some net surfing over airport and syncing my palm pilot and watching a divx movie in a small window. While I know it's bad to have screen brightness all the way up and processor at highest setting, I figure I made up for that by taking out the RAM and putting in a 128MB chip to save the power of having to access all that RAM. Maybe part of the problem is that I also had Norton utilities & AltiVec Fractal Demo running in Classic in the background. I hope this updates lets me do all that and gives me 42 hours of power instead of 20 minutes.

15" 1.25Ghz here

before this update i had a 3:12 battery life, thats with the screen dimmed to 1 bar and the processor turned doen and with BT + Airport turned off.

mAH was 3428 but it only charged to 3427, this mAH had come down from 3600 mAH.

no after performing the update i have 81% on my battery charged, this WAS reporting as being fully charged before the update.

Also now my mAH is 4200.

I cannot wait to find out the new battery life.

I had calibrated this battery last week and the update must of taken this into account...maybe I dunno i'm guessing here.

I don't understand why so many people have problems with absurdly low battery time on their PBs and iBooks. What I really don't understand is the group-think need to slam Apple instead of complaining when you buy your machine. If I had those results with my iBook I would have had it checked out within a couple days of purchase.

Do your part to get it fixed or don't complain. (I know this is unusually harsh and doesn't apply to all cases - use your discretion to determine if you think I'm talking about you. Out of the box battery problems without consulting Apple or demanding a fix is an example of those on the "no-right-to-bash" list.)

My iBook usually lasts four to five hours or more when I squeeze the settings for juice.

Just finished speaking to AppleCare. My battery life dropped from 3:30 to 1:30 after the update. They tell me to

http://docs.info.apple.com/article.html?artnum=14449

- reset the power manager

And if that doesn't work, recalibrate the battery.

To recalibrate the battery though is a bit dangerous if you don't have a backup. If you don't plug the power in in time, your directory may be hosed the next time you boot up. To recalibrate the battery:

1. Let the battery drain until the screen goes dark with Energy saver turned off.
2. Immediately plug in the power and let it recharge overnight.

I just got my powerbook back from repair. The main reason was to have the white spots repaired. I also complained about the battery and had it replace, it was only holding about 2.4 ah. The new one holds 4.4. I just did the batter update and am in the middle of calibrating the battery. While doing this, I burned a DVD, watch about 40 minutes of a dvd I copied to my hard drive. Surfed the net, the whole time I had my airport card on. So far, I have gotten about 2+ hours. Clearly it is calibrating, since it was stuck on six minutes for about 15 minutes. And, then it jumped to 2:08. Now it is about at :13.

Anyway, I would definetely calibrate your batteries before coming to a conclusion about this update. It also should not be too risky. Just run it down while having the adapter ready to plug in. Even if it does go to sleep for a while, it should not cause any problems.

What I did was install the update while plugged in, let it go full. After that I unplugged it and it gave me 2:40. I wasn't worried, installed the 10.3.2 update, restarted that, now on still on my way to re-calibration but I'm at 87% and my meter reads 4:10 left. Don't rely on the battery meter to tell you how long you have to go. Right now it's changing from 3:50 to 4:05, back and forth. I wouldn't worry too much just because it gave you wacky numbers. Most battery timers have to learn how fast your system sucks juice. BTW I'm on an iBook G4 12"

I have a G4PB 1.25ghz w/FW800. My battery life stunk since day one with this thing. Generally I never get even 2 hrs, even with minimal powerdraw. This was beginning to make me actually complain about my laptop. I installed the update and after a VERY long restart, it said I needed to charge for 4 hours!!!

I put the laptop to sleep for about 15 minutes and when I opened it back up it had a full charge. Now I am running it on battery and it is telling me 3 hours remaining. This is VERY MUCH BETTER than it was before by at least an hour. To any PB users with the new laptops, this IS A MUST HAVE!!!

Enjoy.

The battery capacity is still what it was before installing Apple's battery update and recharging. I might have to go through another iteration of this later, letting the battery charge overnight while I'm not using the system. I'd be glad to get 2.5-3 hours from this battery again, which was possible earlier this year after recalibration but it's gone downhill fast the last couple months.

Too bad we TiBook users can't get this update. But then again I'm already getting 3hrs and 45 mins normally out of my PB thats already just over a yr old used everyday. The most I've gotten has been 3hrs and 54 mins. I guess I could get more if I turn the screen down and kill my modem and external mouse. Then I would probably be able to do 4 hr or just over that.

Nobody should be posting or comparing times unless they have actually timed it with a CLOCK before and after the update. How much time do you REALLY get?

The number in the menu bar is just an estimate, affected greatly by moment-to-moment changes in use, and by calibration. The estimate given at first will often turn out to be wrong based on your actual usage of the machine. That's normal, as long as you get your warning when the juice is low.

Now, it's interesting to know how often that estimate tends, over time and many charges, to be close to the actual life. But compared to actual battery life... it's trivial.

In other words, looking at the number in the meter just after the update is pretty meaningless. See what happens in the real world instead.

Counterfit
Dec 17, 2003, 11:17 PM
That's what he meant. It doesn't shut down, but goes to sleep to protect the contents of the RAM. You'd better be near power though, because the internal reserve lasts three minutes at most, but I'm not sure about the reserve held in the main battery. I think I've read 15-20 minutes for that.

I guess we discovered who the fastest gun in the west is. ;)

On the subject, it is taking forever and a day for my battery to charge back up after draining it. I checked about a half hour ago and it said 54 minutes until charged and now it says an hour and 34 minutes until charged. It never took this long to charge before and I've always had decent battery life so I'm sure it's charged up pretty fully in the past.

My battery was fully charged after downloading; after restarting, it needed 15% more charge.

I downloaded the entire X.2.3 upgrade on about 60% of a full charge with a 40kbps dial-up connection. Discharging to 3% after restart...

It seems to recharging faster, too.

BINGO.... my time estimates on my iBook have never been anywhere close to the actual times I get.

The estimate tends to be about 1:30, but I usually get closer to 2:00 or 2:30.

It seems to work great for me. Of course, the experiment is tainted by the fact that this update came on the day I got my powerbook (15 1.25ghz) back from applecare to have the white spot ridden screen and battery replaced. So, I defintely got a boost from having a battery that holds 4.4ah compared to the original one what was down to holding 2.4. Regardless, I got over two hours this morning while surfing the web (wirelessly), and writing some email and what not, and after 2+ hours the meter was still saying I had anywhere between 1:30 and 1:15 left. Oh yeah, I calibrated the battery too. While running it down, I noticed that the meter was really eradict. but, before I downloaded the fix, and calibrated the battery, it was only showing about 3 hours with a full charge. Now it shows almost 4.

But, as someone noted above, that meter fluctuates with use, so it is really only a guide. If you want to know, I suggest collecting some data by running the battery down and couple of times, and marking down the times.

I think that the 8 hour time was just a quick jump while Energy Saver was calculating its actual estimated time. I don't see anything being able to make the battery last that long, although the 4 1/2 to 5 hour time does seem highly likely. I usually got 3-4 easily before the update and even before I upgraded to Panther, so if this update does improve mine, then my 15" will hopefully be in the 4 to 4 1/2 hour range, which would be awesome considering its larger screen, higher processor clock speed and 5400 rpm HD.

After installing the update and doing the calibration thing,

I've got 2hrs 40mins out of it with another 50mins showing on the meter which should mean something around 3hrs 15 - 3hrs 30.

This is with Airport ON
screen brightness on 2 bars
and just mildy surfing the net
a couple of things running in the background but the only active ones are msn and safari.

All in all, i think that represents a significant improvement over before, it did take a while to charge it up the first time though so maybe its like a bug fix whereby the battery used to report 100% charged but it was still not quite at the max level.

BTW: which app can tell you the actual power in the battery and stuff like the charge stored in it? and what are the expected levels for the 15 FW800 battery?

15" ALPB (FW800)

The update caused my reported capacity to jump from 3800 Ah to 4200.

Based on these settings;

Screen brightness 1 bar
All networking turned off
Bluetooth turned off

(iow my "airplane" configuration)

Battery life before was ~ 3:15
Battery life now is reported as 4:00

This was with iTunes playing to simulate a lightly loaded environment.

I haven't tried running it down all the way, but the time remaining before was acurate on mine, so assuming the new reported capacity is there I would expect to hit 4:00
