    I've noticed my battery has been draining more quickly on my MBP 2015. Anyone else seeing this? Even when the lid is closed.

    So you are saying it was fine before upgrading to mojave?

    First night with Mojave and not a good result. Wth Sierra I seemed to lose 3% - 6% if I left my MBPro sleeping from 6pm until 8am. Wth High Sierra that went to 6% to 10%. So at 8am I might be at 94% - 90%.

    With Mojave it's down to 70%.


    Very significant power drain.

    Ouch. I thought HS was bad on battery drain. Mojave is even worse.

    I just reset my SMC and then left it closed for three hours. Lost 7%. Doesn't appear that this made a difference.

    I have the exact same issue with my MBP 2018, did you clean install?

    Same problem here. Mine was upgraded from High Sierra.

    Might be worth an SMC reset. Did nothing for me from a quick 3 hour test, but I'll give it another chance overnight tonight and see.

    One thing that helps when in sleep mode is quitting Safari. Activity monitor shows its the most hog on the system.

    No difference after the NVRAM reset. Slept for 6 hours, lost 10%.

    Well done Mojave.
