Macbook pro 13 inch 2017 W/ touch bar – battery drain during sleep

batteryhigh sierramacbook prosleep-wake

OS Version I'm on is High Sierra 10.13.2

My battery seems to drain way too much on my new MacBook Pro 13 w/ Touch bar 2017 when it's supposed to be sleeping. Things I've done after reading other posts on the issue:

Turned off power nap on battery in the settings
Turned on Do Not Disturb whilst sleeping

After a test yesterday, at the end of a day the battery went from 100% to 84%, I didn't open the lid once in that time.

I don't recall ever having this issue with my MacBook Air mid 2012.

Is this a software, hardware issue or both?

Thanks

UPDATE 01/01/2018 – Happy new year! So I did as suggested in reply. Nothing was open preventing sleep. 20hrs this time on sleep and down to 78%. This can't be right!

If you open Activity Monitor there is an Energy tab that will display what is consuming the most energy. One of the columns is "Preventing Sleep", which will allow you to see if any apps are preventing your Mac from sleeping. It could be that it isn't sleeping when you think it is.

If you leave Activity Monitor open for a while it will gather data and you can look through and see what the biggest culprits are for energy usage. You could have a program that hangs and uses more power than it's supposed to.

To help debug sleeping issues, try the pmset command in the terminal:

$ pmset -g assertions

Assertion status system-wide:
   ChargeInhibit                           0
   PreventUserIdleDisplaySleep             0
   PreventUserIdleSystemSleep              1
   NoRealPowerSources_debug                0
   CPUBoundAssertion                       0
   EnableIdleSleep                         1
   PreventSystemSleep                      0
   DisableInflow                           0
   DisableLowPowerBatteryWarnings          0
   ExternalMedia                           0

Listed by owning process:
  pid 2520: [0x0000012c000009d8] PreventUserIdleSystemSleep named: "com.apple.audio.'AppleHDAEngineOutput:1B,0,1,2:0'.noidlesleep"

In this case, it's the process 2520 messing up. Check it out in activity monitor and kill it (/usr/sbin/coreaudiod started by iTunes).

After that, run the command again:

Assertion status system-wide:
   ChargeInhibit                           0
   PreventUserIdleDisplaySleep             0
   PreventUserIdleSystemSleep              0
   NoRealPowerSources_debug                0
   CPUBoundAssertion                       0
   EnableIdleSleep                         1
   PreventSystemSleep                      0
   DisableInflow                           0
   DisableLowPowerBatteryWarnings          0

2016 Touch Bar MBP drains battery in sleep

I don't know much on deciphering console.log messages but if your machine is physically warm and losing that much battery it has not actually been asleep. It is normal for OS X to wake up every few hours & perform some background tasks but under typical use it should be asleep again within minutes. Yours is definitely doing more than the average machine while asleep.

I wonder what the results would be if you created a new (completely blank) user in System Preferences > Users & Groups, logged out of yours, logged into that user & then put it to sleep for another day or so. If you see that the machine is no longer waking up & for whatever reason not going back to sleep than you can be sure it's something installed on your profile. If it continues to happen it's possible that the operating system is having an issue and may need reinstalled or that there is some kind of crazy hardware issue causing this. It's a lengthy troubleshooting process but it's the only one I know for an issue like this - please update here and I can help out more with this if you do decide to go this route.
