Hey all,

I went to the Apple store yesterday and had another go on a 15" macbook pro.

I really like that you can just press sleep, close it, and then come back to it and it practically comes back on immediately.

Firstly...
How long can the battery last when it is in Sleep Mode?

And Secondly... I think I've heard somewhere that shutting the lid is just as good as pressing sleep - Is this true?

THANKS,

Marky :)
 
After a week or so it'd probably have 10% or something, you couldn't do loads with it before you had to plug it in again. After 10 days or more you'd probably have to plug it in pretty much straight off the bat. I didn't used to do it much with my own machine (I was usually using it it was my main one at the time) and at work they never got left very long, or if they did I didn't know how long they'd been left so hard for me to say personally.

I will say though that I would expect after 7 days sleep from a pretty full battery, you'd be able to use it a little while before plugging in again, but not much.

After it runs out of proper battery, it'll safely save all your stuff and die. Once you plug it in and open it, it comes up as a low-res screenshot of what was there and a little wheel goes round then it all comes back after about 30 seconds.

Is that 10 days and it's dead, or 10 days and it can still be used?

It came up with the "running on reserve battery power" when it woke, so I plugged it straight in.

So after 10 days it's as near as dead as makes no difference. It was, however, still sleeping. The battery power had not got so low that it hibernated.
 
Left my 17" MBP on sleep for ~9/10 hours and it dropped 4% battery, seems reasonable to me.

I've read somewhere that if you're using it until the last drop of battery it wont just shut off it'll go to sleep and use a backup reservoir of battery to sustain the sleep for x amount of hours and then when this runs out it'll turn off completely.

Still new to Mac so not 100% sure where I read this or if it's right :D

It goes into hibernate mode which is different to sleep. The contents of the memory are written out to a disk file, the system state is stored and it shuts down.

When power is reapplied, the system resumes, you see a bar drawing along the screen as it recovers and it comes back in the same state as when it was put to sleep.

The whole sleep/hibernate thing in OS X really is superb.
 
i got my macbook 13" on the 21st of dec, ive done a full charge when i got it and thats it.

i use it for maybe an hour a day tho, before i go to sleep in bed for browsing web.
 
I never shut down my MBP. Only restart it if any updates require it :) Love the fact that I can close the lid, it sleeps, then open the lid...it instantly resumes from where I left off! :-D

Ah, thanks for clarifying and yeah my experience so far is that it's a lot better than Windows, the main attraction is that everything is so pretty.
