Macbook PRO 15"(late2016) draining battery on Sleep

[MrGuder]

^^That post was from July and for some reason I'm no longer losing any % overnight. In fact for the past several weeks or more I'm not losing any %. Last week I charged overnight and disconnected the next morning and I got so busy that I didn't get the chance to open my laptop for 2 full days and noticed it was still at 100% on the 3rd day. This is with wifi kept on and I never power down just close the lid. I have a 2017 15" MBP running Sierra 10.12.5

Battery life is excellent for me and I really love this laptop so glad I waited for this refresh model.

This seems to be fixed in High Sierra.
my MBP has been sitting since yesterday afternoon (some 28h), wifi enabled - and hurray just saw I still have 100% charge.
This has NEVER happened before

The fix mentioned in this link has always worked for me but unfortunately the changes are overwritten anytime there is an OSX update. I might do the changes on more time and hope that when High Sierra comes out it is permanently fixed...

I have the same issue and hope that HighSierra will fix this I love my MacBook but the battery draining really sucks.

I was getting minor drain of around 2% per night but since turning off notifications whilst the screen is off and/or the machine is in night mode the battery is keeping its charge.

In case you didn't notice WhiteWhaleHolyGrail's post a few pages back, this solution actually works; there's no need to change power management settings (pmset) nor everything. Simply go to System Preferences / Notifications and check "While the display is sleeping" in the "Turn on Do Not Disturb" section.



Verified on 10.12.6 with the Wi-Fi left on.

Same issue here!

MBP nTB 2017 (base model, 256gb storage)

Battery drains from 100% to 75-80% in sleep mode in less than 24 hours!!! Been testing it out for the past week (I've only gotten it less than 2 weeks ago) with different settings/variations and apps opened/closed but the results are more or less the same, averaging about 20% battery loss during sleep mode in 24 hours.

Called Apple Support and the guy told me there's no issue with my battery?!

Going to go down to the Apple Store tomorrow. Hopefully someone there will be able to solve this issue. 20% battery drain during sleep over 24 hours is a big problem!

Hi

Just wondering if you've updated to 10.12.6? If yes, do you still get 100% battery life after leaving it in sleep mode for a day with the wifi on?

Hope this works. I'm experiencing the same drain as everyone else, Macbook Pro 15" is closed for the night and burns through 100% of power in about 3-4 days while "sleeping." Yuck.

This is not working for everyone. I tried that last night (on my MBP 15" Late 2016 macOS 10.13.1) and battery level dropped from 44% to 33% in just 12 hours, even with all apps closed. I'm experiencing this annoying issue since the first day with this machine, and the only thing that works is that terminal trick. Unfortunatelly almost every macOS update requires us to do the trick again.

Link for the trick: https://forums.macrumors.com/thread...drain-while-sleeping-here-is-the-fix.2026702/

UPDATE:


Mixolyd's trick does not work anymore. I tried that on macOS 10.13.1 and as he said, it even makes things worse. I'm gonna contact apple again and see if they can solve the issue. Since not everyone suffers from this issue, I think it can be a hardware fault. I suspect that because as in another forum topic that I opened last year, I have some serious bluetooth reability issues on windows 10 via bootcamp, something that also seems uncommon.

sudo pmset -b tcpkeepalive 0 fixed it for me, and I'm running High Sierra 10.13.3

sudo pmset -b tcpkeepalive 0 fixed it for me, and I'm running High Sierra 10.13.3

can confirm, same version, this parameter fixed my battery drain.

don't know why apple get this problem done out of the box.

Curious, when you run this command you get the warning about FindMyMac not functioning properly, which is fine, but I would think it would be follow by a proceed Y/N? I assume it set to 0 regardless of the warning? Also, I assume on is "1" if this doesn't work for me on my 7-8% overnight drain and I want to change it back ?

What is the terminal command to check to see if tcpkeepalive is set to 0 (off).

I know this is an older post, but I just wanted to say thank you for recapping this. I changed this setting on my 2017 MBP w/Touchbar, and it fixed the drain issue. Went from losing 15% battery usage over 24 hours with the MacBook sleeping, down to 3% battery usage over 24 hours with the MacBook sleeping. Thanks!

Not sure if this applied but we have a older style MacBook Pro retina bought just 6 months ago, the one with the older connection ports and NO USB-C. It at times has also suffered abnormal power drain when shut and sleeping. I've checked the settings and can't see any issues.

Will look again with some of the suggestions posted here.

We also have an older 2010 MBP 13" which at times is doing much better when it cones to power drain. Got it 2nd hand so not sure how old the battery is, by an app I installed says its only done 314 battery cycles so it maybe be a lot newer or life its previous life hooked up to mains power 24/7.

BTW we have been traveling over the last week and frequently out of cell and WiFi coverage. We do have a mobile WiFi hot spot and iPhone to link to when needed if this makes a difference?

For those that are still losing overnight try changing hibernation to disk only mode:

sudo pmset -b hibernatemode 25

Only lost 0.x overnight

Can you explain how to do this? I'm relatively new to using "command" instructions, but may be able to figure it out with a detailed explanation.
- Thank you!

LarryJoe33, I was following your efforts on another thread. Did you find that this turn off notifications in Sleep Mode worked?
- Thank you

Hi there, sorry for the late reply. It did not work. I am just living with a battery that dies overnight if not plugged in.
