Mojave: HUGE battery drain during sleep

I have 3 laptops: Macbook Air 2015, Macbook Air 2018, Macbook Pro 2015.


Both Macbook air 2015 and 2018 have Mojave updated to the latest version, the Macbook Pro has High Sierra.


If I full charge them and let them sleep over the night, in the morning I have:


Macbook Air 2015: 12-15% of battery gone

Macbook Air 2018: 5-10 % of battery gone

Macbook Pro 2015: 0% of battery gone


So, it's clear that the problem was introduced by Mojave.


I tried everything: SMC reset, NVRAM reset, clean install of Mojave, disabled useless background services. NOTHING.


The only thing that has worked was the "hibernatemode 25" setting. BUT that's just an "expedient", not a solution.


I want to have back the possibility to let the mac sleep for one week and having almost the same battery charge when i use it again, like it should be for a 1500 € laptop.


Does anyoner if Apple is aware of this problem?


I don't want to use

sudo pmset -b tcpkeepalive 0

sudo pmset hibernatemode 25


because it's not how it should work.


MacBook Air (2018 or later)

I tried most of those steps, but the problem is that I'm not the only one who noticed it, a great % of users that updated to mojave have this issue and seems that Mojave is the reason


I went to genius bar and they said: "everything is normal".


No it's not, because the laptop now loses 15% of charge over the night.

I have the same problem. What made me look for a solution was a warming up on the Mac while sleeping.

macOS Mojave 10.14.5, MacBook Pro (Retina 13-inch, Mid 2014).

Stop working on my mac yesterday at 13:30 PM, battery charged 100%, returned today near 08:30 AM, battery 46%.

This is what i get when running “pmset -g log”:

I will keep the wi-fi turned off while this problem is not resolved.
