Anyhow, we didn't solve our problem, we just changed the sleep mode. It depends on you, hibernatemode 3 and 25 should be the most power-saver. You need to replace hmnumber with 0, 1, 3 or 25 to make it work. We're able to change the sleep mode in use just by typing a specific command: sudo pmset -a hibernatemode hmnumber lastly, hibernatemode 25 is the same as hibernate mode, but is the setting used for newer (post 2005) MacBooks.hibernatemode 3 means safe sleep and is the default for MacBooks made after 2005.hibernatemode 1 means hibernate mode and is the default for older MacBooks (pre 2005).hibernatemode 0 means normal sleep and is the default for iMacs.There isn't just one hibernatemode available, in fact there are four of them: hibernatemode 0, hibernatemode 1, hibernatemode 3, hibernatemode 25. This short command will let you check which sleep mode your computer is currently using, as you can tell by the image I attached below. Then, type the following: pmset -g | grep hibernatemode Let's head to /Application/Utilities/ and open up the Terminal app.

Now it is time to find out which sleep mode your Mac is using. Since 2005, the default sleep mode for portables has been Safe Sleep, but not all Apple portables are capable of supporting this mode. Writing the RAM's contents to the startup drive is a safeguard: whether something bad happens, such as a battery failure, you can still recover your data. Wake time is very fast because the RAM still contains the necessary info.
Apple products, mainly iMacs and MacBooks, have different sleep modes that have been modified over the years. The battery draining issue is particularly visible during standby or sleep mode. I'd like to thank /u/Bananaramaman098 that helped me retrieving more information. Hi everyone, as promised I kept looking for possible solutions and more information about this topic.

I still don't know whether or not Apple has officially addressed this issue, anyhow we should let them know about it.

The issue, as reported in the post on the Apple support website linked below, mostly concern old MacBooks.Īs for me, I bought the 2018 15" MacBook Pro a month ago and since I've updated to Mojave I noticed a slightly worse battery life, especially during standby.
Apple released macOS Mojave about 20 days ago and some users are experiencing dramatic battery life draining.
