Ever since I upgraded to Mojave my MacBook Air battery drains extremely quickly while in sleep mode. I saw the one post regarding DropBox, which I don't have installed. Further suggestions would be appreciated!
Thanks,
Jim
MacBook Air (13-inch, Early 2015), macOS Mojave (10.14.1)
Your full charge capacity is starting to get way lower then your Mac’s batteries design capacity. That could be one possible reason why your Mac is starting to loose charge fast. However, let’s start up in safe mode to rule out an application causing the battery drain. Here’s how to boot into safe mode: Use safe mode to isolate issues with your Mac - Apple Support
Let's check the status of your Mac's battery. Download install coconutBattery and upload a screenshot of the main window of coconutBattery here for us to see.

Just let your Mac be in sleep mode for a while and check the battery life every so often. If your battery drains abnormally fast (8-15% per 30min) I would blame the battery. There could be a program running on your Mac that is draining the battery and I don’t want you to spend money on somethign that doesn’t need attention.
I'll be darned. Sounds like Mojave is the issue after all. Let's try downgrading to High Sierra. Use the guide at the website below to downgrade to HS. When on the "backup your files" step be sure to only use Time Machine for backing up your Mac because the other app they suggest you backup your Mac with is sketchy.
Just wanted update anyone following this thread. The latest update to 10.14.2 (18C54) seems to have resolved the problem.

AJ, what do I do after I start up in Safe Mode? Just trying to figure out before I restart!
Thanks,
Jim
AJ, I give it a try but it was NEVER a problem before Mojave!
It’s possible one of your applications pushed update and is now more power consuming then it was before. Just a thought...
AJ, dropped over 40% in 6 hrs while in “Sleep mode.” Battery life is normal whilpe in use. Sleep mode is the issue since the upgrade!

AJ, I think I'll stick w/ Mojave and hope that they offer an update that resolves the issue since I have seen other posts w/ people having the same problem!
