10.3.7 - indirect battery improvements?

Apparently, the updated graphics drivers require less CPU power, and the effect is an increase in battery life.

I just unplugged my power cord from the fully charged, mains-connected Powerbook sitting beside me and checked what it said - it claimed I'd get 3 hours 40 from it (867Mhz 12"), whereas before it would normally claim 2 hours 30.

Veracity of all this hasn't been checked by me, but it's worth passing on I thought. Slashdot thread is here: http://apple.slashdot.org/article.pl?sid=04/12/15/2227250

Does it, all the 15" PBs are still showing 2:30 of battery time and the USB 2.0 ports are still not powering up host powered hard drives.

1 year old 12" PBook I'm currently running the battery down to see what it will really do. So far it has been running 1.5 hours and claims it has another 50 minutes to go. This is a slight improvement over when I last tried this, and now I am running airport.

When I first tore the charger out, it claimed 1:50, then after fifteen minutes or so, it was offering 2 hours.

(Interrupted by phone calls.) It is now two hours in use with 40 minutes (26%) to go.

I think its an improvement then.

As an aside - I often get caught out by the battery suddenly becoming empty and the machine shutting down. The visual indicater on the task bar is is i is just not enough for me, it being so small and my eyes being so crap.

Is there a third party proggie that will audiably yell at me when the battery gets low ? I'm pretty sure there is no built in option for this in the system preferences.

does it not pop up a your on your on resurve battery life now? i get a warning then if i ingnore it it then sleeps when it gets to zero.

only time i get caught out is when the battery is nearly dead i sleep the powerbook, then wake it few hours later and it wakes and then promply sleeps till a give it some power.

A short furtle on versiontracker.com got me this SlimBatteryMonitor developer site: http://www.orange-carb.org/SBM/ I'm trying it out now. One of the options is a warning at x% battery left. In combo with spoken alerts, it will do as you ask.

1.5GHz 15" PBs are fine, they are showing between 3:30 to 4:00 with 8 cells batteries, but the 1.3GHz 15" PBs have very inconstant QA check, some came with 8 cells, some have 6 cells, in our case the last order of 15" PBs were all 6 cells and have half neutered USB 2.0 ports which Apple UK still insist they never hear this problem when on their own forum board you can find people's complains about this.

Mine slept at 2:30

After I posted that and it went to sleep for a while as it does on battery juice, it then woke up and informed me it had 5 and a half hours of life in it. Then as soon as I started using it it said only two and a half hours. It then fluctuated madly.

It's all a mystery to me - and obviously to it too !

Well my 3 year old 15" TiBook, which was last battery calibrated maybe six months ago, is saying 2:40, running 10.2.6, screen fully bright. It's counting down about a minute each minute which looks good. But I reckon I'd be lucky if it actually made 1:40. The usual trick is to reach around 1:50 while indicating 50 minutes to go, and then to dive south and need charging within 5 minutes.

I don't mean that this is relevant to 10.3.7 except in that time-to-run is always a bit of a lottery.

I didn't expect better battery performance from this powerbook, compared to the Titanium 550, as this one has a faster/ larger capacity HDD and the 128MB graphics card. I used to get 4+ hours from the Titanium. I might unbox and give it a full charge to see how good/ bad the battery is now.

I'm too wary to upgrade. I've been stung by batery management issues before (once, completely destroying the battery) so I'm not upgrading until it looks like the battery management is just whacky, rather than actually dangerous.

I couldn't say which of those it really was - wacky is what I'd call it but I'm not planning to be far from a power outlet in the immediate future so I can afford to take it less seriously than some.

10.2.6, I think, had a whacky power manager that reported the battery as having lower and lower charge; eventually it lasted about 20 minutes (whether the battery had charge or not is still unknown, but the manager thoiught it was near-empty). Apple replaced this as a "good will gesture" after much badgering [1] and it lasted a few months. A subsequent update (10.3.1? - Nov '03ish) did the same but screwed the new battery so badly that it eventually didn't even recognise the battery was present. This time Apple weren't interested - "batteries only have a 3 month warranty, sorry".

Both issues were widely reported on t'internet, and a google here will have me whinging and complaining. The first time, Apple released the update, pulled it the next day, and realesed a 'fixed' update a day or two later; I was too quick off the mark and picked up the dodgy update. The second time around, I sent a letter to Apple but they told me to go screw myself.

Wild fluctuations in estimated time left seem to be an issue that is making itself apparent ATM. More than that we will just have to wait and see.
