MacBook Pro late 2016 battery discharging when shut down

I am not sure if this is possible, but make sure it is not connected to a power source via the USB C charger. It may be causing it to come on after you shut it off. I am having the same issue. My MacBook Pro 2016 with touchbar was at 86 percent after about two or three days. Maybe try turning off the wifi and the bluetooth before turning it off. That is what I am going to try tonight. I am only at a battery cycle of six and I am planning on keeping it as low as possible. Hopefully that will help!

Thank you, please keep us posted. So far I have done SMC reset, turned off Fast Startup in Windows 10 (I have bootcamp installed), turned off bluetooth which sometimes turns back on after restart. I havent tried turning wifi off before shutdown yet. I have also calibrated battery by doing full charge/discharge cycle. On average I lose 2-3% every 48 hrs or 1-2% every 24 hours. Batteries self-discharge on averge 1-2% per month but after several days of reading through similar threads I am slowly starting to believe that self discharge of 1% per 24 hours while off could be normal just not enough user feedback to confirm that.

I have had the same issue with my 2016 MacBook Pro non-touchbar. I shut down the computer and within 18 hours I lose 2-3% battery per the meter and 100-150 maH between uses. I took it to the Apple Store today and they ran diagnostics. Everything came back normal and the Genius Bar rep said this was normal. I told him my girlfriend's 2013 MacBook Pro doesn't drain 1 percentage point under the same conditions. They sent my computer away at my request for further evaluation. I'll see what happens next week.

Hi,

I,have the same problem.

My MacBook Pro (13" late 2016 with Touch Bar, 17 charging cycles) is draining about 6% battery per 24 hours when completely switched off using shutdown (in standby mode with lid closed, the battery drains is about 15% per 24 hours).

I had many MacBooks by the past but it's the first time I encounter this behavior.

After several tests, the Apple Store Genius said my battery health is OK and then asked Apple engineering. The answer was: normal behaviour with the new hardware generation.

Not convinced (I have a Surface Pro with "new hardware" and no battery draining problem when switched off), I asked for a second set of tests in comparative mode (with other machines).

Battery drain when switched off has been confirmed with a machine identical to mine (6%) and a MacBook without Touch Bar (4-5%).

I am very surprised about the results. How a machine can stay "up to 30 days in standby time" if it lots 6% per day when switched off (and then completely discharged in 17 days), and two or thee times more in standby mode?

I don't understand their explanation either. If the battery should last 30 days in standby mode, it should not drain that much while shut down. The Apple rep at the Genius Bar said that's it normal because the battery loses capacity over usage. I get that it will not last as long with usage but that doesn't mean it should lose 2-3% while off. It just means it won't last as long while on and being used. My girlfriends 2013 MacBook Pro has approximately 260 cycles and doesn't lose one percentage point while off after 24 hours.

Did Apple send your laptop away for further testing and give you the response that your experience is normal? I am waiting for mine to come back to see what they say but I think it'll be along the same lines as what you heard.

I tried turning the Bluetooth and Wi-Fi off before I shut the MacBook down and it had no difference. I lose easily six to seven percent of my battery charge per day or twenty four hour period. I now keep it plugged in all the time, even when it is turned off. This need a to be fixed, because my fear is within a few years, the MacBook battery will be useless anyways.

No, and they gave me back my computer saying they could not do anything because, for them, the situation is normal comparing to other machines of the same generation.

They can change my battery but I have to pay because no hardware problem has been detected (and thus not covered by warranty).

The genius technician thinks that some hardware is not shudown properly (like touch bar components), and perhaps requires a firmware update, but not available for the moment.

I ran several clean OS installation, many configuration changes and I always note the same problem. Otherwise, the terminal command 'pmset -g log' shows that there is no activity when my computer is switched off... And to finish, my battery has less than 20 charging cycles...

All of these sound very strange. Please, keep me informed about your situation.

Hello everyone,

I just want to report that I am facing the exact same issue. My 2016 touch-bar MBP15 discharges by about 2%-5% per 24 hour period when it is in shutdown. Looking at the logs I can't see any activity between shutdowns, so it seems unlikely that the computer is waking up for some reason and hence consuming power. I have tried resetting the SMC as well as turning off the boot-up on opening the lid feature and neither has solved my issue. An interesting thing that happens when you disable the boot-up on lid open is that as soon as you open the lid you get a battery icon on the screen with the percentage that you have remaining. It looks like this is a feature meant to give you a quick battery reading reminiscent of the LED indicators on the side of older MBPs. The reading appears for a few seconds and then the computer goes back to "shutdown".

As mentioned by others in this forum I haven't seen similar issues with older MBPs. My work computer is a Mid 2015 MBP15 and I don't lose any battery in shutdown. In fact while I was on vacation for 14 days the computer was still at 100% when I came back. My older, personal mac is a 2015 MBP13 and for the same 14 days period it had lost only 3%, while the 2016 touch bar MBP15 had lost nearly 50%.

The only other device where I have seen a similar problem is a 12'' Macbook first generation. BTW, all of these devices are updated to the latest version of macOS Sierra (10.12.6).

Hi,

I carried out some tests in sleep mode (by closing the lid) with the smallest possible energy footprint.

I disabled :
- Wake for Wi-Fi network access
- Power Nap
- iCloud Drive
- Find My Mac
- TCPKeepAlive (sudo pmset -b tcpkeepalive 0)

I enabled :
- Turn on Do Not Disturb when the display is sleeping

Within a 24-hour period, I observed (with pmset -g log) only one darkware, three hours after closing the lid, to turn the mac in hibernate mode.

After these 24 hours, the battery was discharged about 6% (1% for the first three hours)... So the result is identical as completely shutting down the Mac...

So, I'm sure that something, like a hardware component, is draining the battery when the Mac is completely off.

Please, share your experience on these MacRumors thread to share you experience:

I really hope Apple will catch onto this issue, but being that it is a hardware issue and not software issue (an simple over the air update fix), they probably will not want to deal with a recall to rectify the issue. If enough people bring this issue to light, then hopefully the problem will be resolved...

It is not a firmware problem. This is a hardware issue that is happening to people with and without the touchbar. Something is not right here. I have had multiple MacBooks. I have an older 2008 MBP 15 inch that does not discharge anywhere near six percent in a 24 hour period and it has nearly a 400 on the battery count cycle! My 2016 MBP with touchbar goes through at least that when shut down, if not more, and it is only at seven on the battery cycle. I keep it now constantly connected to a charger. That is sad....

I ran a very similar test last night, in my case putting the machine in sleep mode and disabling only the WiFi. I got pretty much the same battery drain as in full shutdown, so I second the opinion that this is some hardware component that is not shutting down properly. I really hope Apple looks into this!

I got my MacBook Pro back from Apple repair and they ended up replacing my top case with battery. The issue unfortunately still remains. I am still losing 2-3% a day even with a new battery.

Not sure at this point what to do. I don't think there's anything they can do if I take it back. Also do not want to be without computer again for a week.

One thing to note. I don't remember this being an issue the entire time I've had computer. This has become a problem since the last two sierra updates I feel. Hopefully someone here finds a solution and can post about it.

Hi,

After several calls with Apple Care, the engineering answer was always the same: the 5% / 24h discharge when the computer is completely off is the expected behaviour !

But good news...

After updating to High Sierra this monday, my MacBook Pro didn't discharge when off since 3 days ! 0% / 24 h !

Contrary to what Apple says, there was indeed a bug with Sierra.

I'm going to do some test in sleep mode now.

I have different results. I upgraded to High Sierra, and the issue is somewhat addressed, but certainly not fixed to the point of 0% / 24h. My losses were anywhere from 3-5% per day shut down in Sierra.

with High Sierra:

65% on shutdown (8:09 pm)

64% on boot next day (1:58 pm) ... 62% by 2:01 pm (3 minutes later!)

... so, that's a 3% loss, just slightly disguised.

next day:

61% on boot (6:31 pm) ... 59% (6:32 pm, 1 minute later)

... another 3% loss (62% shutdown, 59% 1 minute after boot)

I haven't yet done a 2 or 3 day test, but as far as I'm concerned, it's still failing the overnight test. The only difference is that High Sierra seems to overestimate on boot, then settle to the real number within two minutes.

Mine is a late 2016 13" MacBook Pro with Touch Bar. Arrived from manufacturer with 0% charge. 8 battery cycles total, so far. All tests normal. SMC reset. High Sierra installed.
