Mojave: HUGE battery drain during sleep

It's quite frustrating!

I did as B3N14M1N suggested and opened a bug report.

I'm still making more tests to see if I can find a better solution for the time being.

Tonight I'll test Handoff off with Power Nap disabled and Allow Bluetooth devices to interrupt sleep disabled.

My notifications are off when the lid is closed (I don't see any reason to enabled them when the lid is closed).

I'll post here the effects of these options on my battery life overnight.

I've been having this issue too for a while. Maybe since upgrading to Mojave.

Closed my MacBook Pro (Retina, 15-inch, Mid 2015) yesterday at the end of the day, disconnected it from the charger, stored it in a closet. Came back this morning and my battery was fully drained.

Please report this as bug to Apple. The more of us, is better.

Did anyone installed macOS Catalina Beta? Maybe in Catalina it is fixed. I reported a bug with huge battery drain but they did not respond.

Ehh...I am going to ping them until they will fix it.

A 8-hour test. The battery went from 99% to 96%.

For some reason, Handoff was not preventing sleep. It was enabled, but pmset -g assertions showed no problems.

Power Nap and Allow Bluetooth devices to interrupt sleep were disabled.

It's better, but not as good as my Macbook Air 2013.

Tonight I'll test with hibernate mode 25 to see the effects.

Today 67% in the morning . Now it is 44%.

Also I noticed that when you close the lid e.g with 67% after few hours you open it, and do not login it shows 67% in the task bar.

When you login to account then it refreshes the battery % and updates for example to 44%.... Apple i call you for action.

BT OFF. WiFi ON.

Does anyone from the Apple's technician can reply to our needs?

Are there any commands to track down the reason of this issue?

I looked at /var/log/system.log and found nothing interesting.

I contributed early in this thread but unfortunately I don't have time to read all of the recent posts.

If someone has an external drive housing, or possibly even a good quality fast read/write usb stick or SD card, they could try the following and report back. (You know, one of those blazing fast SD cards that cost a hundred bucks!)

1, Install mojave on the drive but do not migrate or install any of your personal files or Applications, or set up any iCloud or email or any other kind of internet account.

2, Restart while holding down option key and select the new drive as the startup disk.

3, Go to utilities, disk utility and eject (unmount) the internal drive.

4, Go to the App store and install any updates to Mojave.

5, Test the battery drain.

And report back here. Forgive me if this has already been suggested.

A 16-hour test.

Using hibernate mode 25 I was able to keep the battery at 100%.

Handoff on - Power Nap off - Notifications off with lid closed - Allow Bluetooth devices to interrupt sleep disabled.

Try this and tell if it works with you guys.

Yesterday evening I closed all application windows, then shutdown my MacBook Pro 15" Mid 2015 with Mojave. Started it up, closed the lid, disconnected the power. Came back this morning and found out the battery percentage dropped by 5%.

Using pmset -g log I found the following: Total Sleep/Wakes since boot at 2019-06-13 21:58:33 +0200 :9

So it woke up 9 times while I expect the MacBook to just stay asleep when not on battery power.

Digging through the log from previous times my battery drained fully, I noticed this in the log:

2019-06-13 11:08:15 +0200 WakeTime WakeTime: 142956.065 sec

Usually WakeTime is just a couple of seconds but it seems that it woke and stayed awake until the battery was completely drained. This is not good.

Last night the drain was just 5%, but I think that's because I closed all other programs.

In the logs there's also a lot of entries for Carbon Copy Cloner and Time Machine backup. So I have the feeling they somehow wake up the MacBook even though I've disabled "Back up while on battery power" and also in CCC I've enabled to "Start scheduled tasks only when computer is running on AC power", which is the default.

Charged fully: 100% (00:50:00)

Morning 85% ( 09:25 )

No apps running.

For me there is nothing in the log which is suspicious. Maybe someone can see more.

Thanks for any help

I tried with sudo pmset hibernatemode 25 but the MacBook still wakes up from sleep. Last night it woke 10 times over a 16 hour period. So for me it's not solved by setting hibernatemode to 25 and it seems to influence how connected USB drives are handled when going to sleep. Before hibernatemode 25 I didn't have any issues closing my MacBook with a connected USB drive. But now when I open the MacBook I get the "Disk not ejected properly" warning.

I'll try also with sudo pmset -b tcpkeepalive 0 but I don't think it's going to solve my issue. I just want the MacBook to stay asleep as long as the lid is closed.

Last night the battery stayed at 100% using the suggested workaround:

sudo pmset -b tcpkeepalive 0

sudo pmset hibernatemode 25

I'm seeing a pattern in my wake events. Carbon Copy Cloner is definitely waking the MacBook every 2 hours. I've got a backup task scheduled to run every 2 hours, but only when the system is running on AC power. So I guess CCC wakes the MacBook to check if it's on AC and then go back to sleep. Which is fine I guess, now that it won't stay awake for long and not drain super quickly.

I'm going to try also without sudo pmset hibernatemode 25 to see if that's enough. Strangely I didn't yet encounter any "Disk Not Ejected Properly" warnings, which I was getting yesterday. So if that doesn't show up again, I'm fine with the workaround for now.

Turns out I didn't set "Run this task when the system next wakes" in the CCC schedule configuration (unique to each task, not global via preferences). Had it set to "Wake the system" before, so with this change I expect the MacBook will stay asleep.

Over a 21,5 hour period I lost just 1% of battery, a big improvement. Over this time the MacBook woke up 3 times due to MaintenanceWake. Also CCC didn't wake the MacBook any longer. I didn't use hibernatemode 25 (it's back to the default, 3) but I still use pmset -b tcpkeepalive 0.

I've noticed my macbook is logging several "DarkWake from Standby [CDN] due to ARPT/Network: Using BATT" activities. I'm also getting several logs of "driver is slow".

Does anyone have any ideas?

I had exactly the same problem on my MBP 2015

Would ordinarily get 9-11 hours use out of it on high Sierra and wouldn't drop percentage overnight if I left it on sleep. On Mojave it would drop down to 40% regularly overnight and I would be lucky to get 3 hours out of it.

Downgraded back to high Sierra and battery life was restored to what it was pre upgrade.

Pretty obvious its Mojave that was causing my problem and I have no intention to upgrade back to it because its just a bit crap really
