Put my machine to sleep last night with 41% reading on the battery. Didn't use it at all, up this morning and it's reading 0%. In fact it initially refused to switch on, though I'm typing using my allegedly 0% battery right now.
It definitely went to sleep - I had the pulsing LED on the front. Any idea what could be causing that kind of drain?
(if it's accurate of course - 0% detected but it's still going fine at the moment and has been for about ten minutes now)
Cheers, Ian

Did it wake up again during the night? The console might show something.

There's that too. What does CocoaBattery tell you about the state of the battery?

It does sound as though the battery has developed a fault- after all, all it takes is one cell of many to gat an internal short circuit. Not a dead short, but a drain...
Which, given that it's a MBP, sounds like a warranty job to me.

If so, it's easily testable - do the same thing again.
I've had my MacBook wake up in its bag once, and stay awake long enough (at least three hours) to drain the battery. Only once though, so it was surely a software fault, and it didn't do any apparent damage.

A good question, apparently my searching skills are weak today because I can't actually find a download location and versiontracker, my normal finger of things, isn't listing it. Where is Cocoa Battery please?

Was it not Coconut Battery?

Well I've got a similar MBP battery symptoms - goes to sleep with 30 - 40 percent. In the morning it has zero and it does seem to be close to zero because it soon runs out altogether. Downloaded Coconut Battery just now and the interesting stats are Current battery capacity or 4861 mAh compared with stated original capacity of 5500, or 88 percent. Interestingly, it thinks my battery charge cycles is 4 when it is actually 164. I checked my MBP and battery serial numbers on the MBP battery exchange page and it doesn't qualify - it's not showing any signs of swelling or the like. You probably know that the calibration instructions for newer laptops is to charge 'em fully and leave 'em on power fully charged for a couple of hours before running them down till sleep and leave in sleep for at least 5 hours (or until they shut down completely) and then charge 'em fully again. Gonna try that as I've not been that systematic about it lately. Might give Applecare a bell if no improvement. What does Coconut Battery say about your numbers?
Cheers D

OK, well now then it says this:

...which I must be honest I don't know how to read. Seems to have two current sections - what's that saying?

To make it more confusing, does current mean amps, or "now" :-)
I think what it says is that your battery is at 64% of its actual maximum, but its actual maximum is only 44% of its original maximum. In other words, it is at 28% (1570/5500) of the original maximum, and it is buggered.
But it is worth doing a full charge/discharge cycle just to see if it just needs re-calibrating.
Cheers,
Chris

At 2426 mAh capacity compared with original cap of 5500 it looks like it's wearing out before it's time. Have you tried the prescribed callibration that I am doing at the mo'

... and check carefully the apple site, because they have a return policy that extends the warranty in quite a lot of cases for MBP batteries. I got mine replaced for free 2 years after buying it, because it indeed respected the criteria (less than n discharge cycles, turning thicker than its nominal size...)

Yes, there's more than one route to a battery replacement if you've got an iffy battery. See the latter part of this: http://www.apple.com/support/macbook_macbookpro/batteryupdate/
I am going to go this route if the by-the-book calibration I am doing doesn't work.
