Battery Drain When Lid Closed

I thought that when I closed my rMB's lid that it would go to sleep, saving battery power. However, it seems like I always see a big drop in battery capacity when I close the lid.

I am running OS X Yosemite, version 10.10.3. Any recommendations?

any adapter connected to it (USB/HDMI/VGA)?
 
When my lid is closed the laptop is still sending and receiving data through wifi. I noticed about 5% drop in battery throughout the day with it's closed.

Check the power nap option on battery mode in the energy saver settings

That's exactly what it is

With power nap, your macbook performs tasks and updates even when the lid is closed

You can disable this if you wish, but I only see a 2% deduction tops overnight

What exactly do you consider a big drop? >5% or something in the 10-20% range?
 
I had the same issue with mine (along with lower than expected battery life). Power nap doesn't change anything (it's not even available for "running on battery" settings). Only way to circumvent that would be to turn off wifi before sleep.

The MB does wake up several times, and is ALWAYS connected to wifi (which is why there's no delay when waking it up), unlike any other Macbooks. My MBA doesn't do that, and I never lose even 1% of battery life over several hours of sleep.

I sure hope Apple solves this with a software upgrade. Some of us would rather save battery life and wait a couple of seconds for the MB to reconnect when waking up.

15%. It's like the computer is running by nothing is being typed.

I've seen in even when wifi is turned off.

Check the settings again. Even when tethered to my iPhone all day (but not using it) I only see a 3-4% drop from a full charge.

On the new MacBook the tethering doesn't sever when you close it, but it doesn't seem to matter because the charge level is barely affected. I also leave WiFi on but that doesn't seem to matter either.
 
I upgraded to 10.10.4 for no reason other than I could.

Last night I charged to100%, unplugged the rMB and closed the lid at 830 pm. This morning at 6am still at 100%.

observed the same problem on 10.10.3 on the new macbook. When I check /var/log/system.log I saw a bunch of these errors. Searching on google only return 1 post regarding this issue, but no solution.

Anyone can try to open terminal and run

cat /var/log/system.log | grep -i "wake reason"

and that should show you why your battery is draining.......

I'm starting to wonder about my battery usage as well - had 70% last night, used it about half an hour web browsing, this morning its down to 35%.. :confused:

Are there any apps that can record battery usage? iOS does this natively so surely there must be something - would give us an indication as to what's going on..

Cheers

Any USB adapter connected during the night?
 
Same issue here, whether or not wifi is disabled. Nothing at all connected to the USB port
Hoping 10.10.4 fixes this
 
I was worried about this as well since people had mentioned it but I had it plugged in, then I closed the lid, unplugged it, left it on overnight and the next day the battery was 100%.

I didn't use any disk migration or anything with my new rMB.

Question for all of the people having this problem, Did you use some kind of migration assistant or time machine back up for your new rMB? Maybe some setting carried over that's causing your computer to wake?
 
I don't see this issue either. There must be some process which is waking the machine up constantly.

My computer stays at the 100% for a long time. Suppose you are at 43% and close the lid.
 
Drain is ridiculous

The drain is ridiculous to the point I have to shut down the laptop instead of just closing the lid. Left it closed for half hour and battery dropped 2% and when overnight it drops about 10-15%. Migrated from previous TM backup. I'm hoping the new version of the OS will fix this. Other than that, love the laptop.

I believe your issue is your TM migration. The way you can test and be certain for yourself, is to boot up with a virgin OS X build (either by doing a clean install of 10.10.3 on the SSD, or the same on an external USB drive that you can then boot from), and let the rMB sleep overnight. Willing to bet that will remedy the issue you are having.

When moving to a new Mac, I always do a clean install and move my apps and data over manually, to both use this as an opportunity clean out the cobwebs from the previous machine, as well as avoid adding problematic crud that can cause issues for the OS. Bottom line: I'm not losing any battery life overnight on my rMB with a clean installed 10.10.3.

Mine is a new setup, and the battery still drain when the lid closed an it's on battery.

Log file /var/log/system.log always show and wifi wake on LAN is already turn off.
