How much % does your battery use when in Sleep Mode?

[CSilver]

i left my Alu macbook over night in sleep mode, went from 78% to 16% :/....

Try a Calibration method. Drain it completely and remove it from the Macbook. Let it die for about 8 to 10 hours then recharge. That worked for me to solve the sleep mode battery drain problem. I hope that helps

Well lol If I would of left my macbook sleep overnight mine would of been from 76% to umm... 0% lol Since mine lost 10% or more sometimes less per hour before I fixed* the problem.

sorry to bump up an old thread


i lost about 10% in about 6-7 hours in sleep mode.

not bad , but not the 1% per hour that people are saying is normal.

i also experience the seemingly fast drain that CSsilver is describing. the percentage points seem to be going down every few minutes just surfing the web, even though it still says i have about 3 1/2 hours left (at 72%)

When you put your Mac to sleep over night, doesn't it get annoying when the light at the bottom keeps going on and off, also when I have my mouse attached to my Mac while its sleeping it kind of wakes up with lid down then goes back to sleep... strange, and my battery sucks now lol, ill probably loose 10% of battery in 1 hr...

it sounds like 1-2% per hour (in sleep mode) has been the norm for many unibody macbooks and mbps.

kinda sucks.

the high battery drain under light load is kinda odd also (im even using coolbook to undervolt).


is apple even looking into this or are they saying its 'normal'?

There seems to be a problem with 10.5.6 and the Macbook/MBP and sleep.
The default of sleep/hibernate seems to drain the battery a lot faster than previously.

I have found that the SmartSleep preference pane http://www.jinx.de/SmartSleep.htmlhttp://www.jinx.de/SmartSleep.html
helps prevent thebattery from draining too quickly. I have set the pref to "sleep only" and that seems to have solved the problem for me.

"Sleep only" helps your batterylife in sleep mode?? I thought it would make it worse


also my battery seems to take a long time to charge. i had the battery down to about half and plugged it in, it's been saying ~2 hours to full charge for a wile now and its at 68%

I tried on my Unibody 2.0 this night:

12 hours of sleep
97% starting
89% at wake up

0.67 / hour

Seems pretty good to me.

Health: 100%
Cycles: 13

Apple says that in sleep mode, power is supplied to the RAM.

so i imagine if you open iTunes, Safari, iPhoto, Photoshop, and a few finder windows + be paused in the middle of an HD movie

that your battery life would decrease significantly more than if you put your MacBook to sleep while having nothing open.

I'm not sure you understand. Why would it use more power?

Power is supplied to the ram, yes, but it doesn't use MORE power just because there's more data on the RAM. It's not like it only powers up the "used" parts of the RAM. Data is data no matter if it is a movie or Photoshop.

Just got back from Bali and notice that battery power is a lot worse than before. I seem to be losing about 1%/minute when doing surfing (wireless with 9400M), on sleep it loses about 2%/hour. Help!
