    So I really like my base model gold macbook so far minus one nagging issue that seems to have no resolution. I am open to suggestions and will list below the few things I have tried.

    Issue: rMB looses 40-50% charge overnight (10 hours between use) while off of the charger and in sleep mode. This is odd as while it is under heavy use I can get a solid 8 hours of battery with the screen on. Something odd is happening with the screen off that I can not resolve causing huge battery drains.

    Things I have tried with no success:

    - Day 1 Restore rMB and set up as new
    - Day 2 Close all apps before putting to sleep
    - Day 2 Check activity monitor for apps preventing sleep (none)
    - Day 3 Try the newest beta for El Cap
    - Day 4 Turn off location, bluetooth and wireless before putting to sleep
    - Day 4 Look for "idle wake processes", discovered kernel_task if fairly active however no more so than on my neighbors iMac...
    - Day 5 Restore to Yosemite and set up as new, installing no apps
    - Day 6 Called apple support, explained issue and was instructed to run a hardware diagnostic. No issues found. Checked battery health and all is normal. They asked me to check for updates, there were none. Was told to bring it to store for analysis.
    - Day 7 took to apple store, the suggestion was to allow them to keep it for several days for testing. This is not a viable option at this time as I am wrapping up 2 summer online courses and need the rMB as it is my main computing device.

    Any ideas would be greatly appreciated and thank you in advance.



    RESOLVED:

    Called apple again today to see if I could get a senior advisor. I was very fortunate to speak with a very knowledgeable young lady, Lynn.

    She was able to solve the issue in a matter of moments. System preferences>Users and Groups>Login items

    Here she advised me to select and removedrop box. After 4 hours of sleep my battery is still at 100%. Not an apple issue, a bad dropbox update. Updated dropbox this evening and reenabled it as a start up item. No drain yet.

    Try this in Terminal:

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

    Lets try to narrow it down, run the command after you wake up the Notebook manually from a nights sleep. The Dark wakes are indeed the concern, there is a solution, equally if the root cause can be isolated it`s obviously better.

    Goes on like this forever, I had to shorten the log as it was too long to post. What is perplexing is I am turning the wifi off prior to closing the lid however when I open the lid half the time it is connected again.

    Yes I see your Mac is basically continuously wanting to connect to the network. Set your Notebook not to sleep in preferences and than leave it over night, reset back to default and observe what happens. This one of the worst instances as I have seen with your Mac literally waking up every 10 seconds or so.

    Interesting. I wonder what the conflict was that caused that? I'm running Dropbox with no issues.

    What version of Dropbox? I updated to the newest and have no issues now. That may be the difference.
