Horrible battery life while sleeping with Mojave

My 2014 MacBook Pro only has 161 cycles on the battery. Before Mojave I only had 99 cycles. It stays plugged in a lot to a monitor, but now if its off the charger and asleep I lose about 40% of the battery over night. Since Mojave just using Brave for 30 minutes to web browse it drops about 45-47% of the battery.

I'm probably going to downgrade at this point as its not worth it.

 

Use MacPilot software to enable "Standby delay"

 

Sleep is totally broken in Mojave. High Sierra was bad but Mojave had a few too many and went all in.
You can force it to hibernate and I think you lose Find My Mac.

I just shut it down and don't bother with sleep if I'm away from my charger for an extended period. That way at least Find My Mac will work when it's turned on again (hopefully).

EDIT: It is worth going through all the settings anyway, there are things you can optimize. The Bluetooth Wake options, enable Do Not Disturb, disable Power Nap. Those won't fix the issue but they might mitigate it somewhat.

 

Issue is caused by 3 hour default until sleep turns to hibernate. I changed this setting to 30 mins and now battery behaves normally. (something in standard sleep is causing too much drain).....
sudo pmset -b standbydelay 1800

 

Noticed that too. Standby time is just trash now on Mojave.. Its sooo bad now im turning off my notebook instead of putting it on standby.

 

I did a clean install of Mojave and somehow mine was set for 24 hours. Craziness.

 

My MBP on Mojave 10.14.3 has a standbydelaylow? of 3 hours and standbydelayhigh? of 24 hours by default.

Code:

bash-3.2$ pmset -g | grep standby
 standby              1
 standbydelaylow      10800
 standbydelayhigh     86400
 highstandbythreshold 50

 

I had this issue as well. I solved it by enabling deep sleep (hibernate mode 25) and lowering the standby time to 3 minutes.

You can do this by running the following terminal commands:

Code:

sudo pmset -a hibernatemode 25
sudo pmset -a standby 1
sudo pmset -a standbydelaylow 180
sudo pmset -a standbydelayhigh 180

Battery drain overnight has gone down to (almost) zero. Wake time from sleep is a bit longer though (about 5 seconds more in my case), so there is a small trade off there.

 

Has this issue been resolved in 10.14.4? It certainly appears much better for me now. I left my MacBook Pro sleeping for several hours yesterday and it only lost 1% whereas before it was losing 5% or so in just an hour.
