Short sleep times

[Eallan]

I have a late 2010 core i7 macbook pro.

It seems that it burns through battery pretty fast while in sleep mode.

Last night I took it off the charger at 4pm. This morning at 7am it was at 79%.

21% in one night seems terrible for sleep mode.

Thats unusual. It would usually drain about 1% per hour.. whats your cycle?

15 hours is a pretty long night, isn't it?

21 % drain after 15 hours is about 1 % per hour (exactly 1,4 %).

21 % drain after 15 hours is about 1 % per hour (exactly 1,4 %).

So this is to be expected? I had a 2008 MBP and i swear it was much more conservative in sleep mode.

Perhaps my iPad ruined expectations haha

- No, I would say that 21 % after 15 hours is a bit much.

If it bothers you, have a look at the different settings for the laptop's sleep mode, here: http://www.macworld.com/article/53471/2006/10/sleepmode.html
If your computer needs to sleep for a long time, you could set it to mode 1, which will not drain any power at all.

I have mine set to mode 0, which means it goes to sleep faster than with the default setting.

It sounds like your Mac didn't stay in sleep mode all night.

Thanks for those. The syslog shows that it only woke up when I opened the lid so it seems it stayed asleep all night...

Did you have any device plugged into any port?

Nope, zipped up in a bag. It's kinda been an ongoing thing. I'm usually pretty surprised at how low it is.

It's consuming a bit more power than normal during sleep, but not significantly so. Around 1% per hour of sleep is normal, and you're at 1.4%. You might try resetting the SMC. Instructions are in the Battery FAQ I posted, under CHARGING.

I think i'll do that. Never have on this machine but i recall doing it to my old one. Thanks.

Just for reference: My machine has used 8 % since I put it to sleep yesterday - that was 10 hours ago.

Thank you, good to have comparisons.
