With the lid closed, my Macbook Air (13” 2020 Intel (MacBookAir 9,1), macOS 14.3.1) drains battery, usually at a fee of greater than 10 proportion factors per 24 hours. I’ve tried the same old voodoo of resetting PRAM, SMC and whatnot and have even gone so far as reinstalling the OS. Earlier than that, I had tried turning off every part that appeared associated to background sync, together with logging out from iCloud, with no obvious impact. I turned these issues again on. “Wake for community entry” and “Energy Nap” are set to “energy adapter solely”. Energy financial savings mode is at “when on battery energy”. Battery well being is “regular”. There’s nothing electrically related (USB or 3.5 mm earphone jack) to the pc.
What’s the pc doing that’s so necessary that it must occur all evening, with no one watching it?
pmset -g log exhibits two sorts of DarkWake occasions: EC.RTC and EC.ARPT.
The RTC occasions occur commonly, normally an hour aside, however generally two hours.
The EC.ARPT occasions happen in bursts, with about one occasion per minute, over a interval of an hour or so. These are, judging by the explanation (packet knowledge dump) given within the pmset log and snooped community visitors, attributable to incoming packets on an already-established TCP connection on distant port 5223, distant host eu-north-courier-4.push-apple.com.akadns.internet or any of a number of comparable domains.
log —present for the time round any of those occasions exhibits a number of thousand traces of output!
Pretty usually, the machine sits properly idle, briefly waking up each one or two hours in the course of the evening, however then has a type of EC.ARPT bursts, lasting one or two hours, round six o’clock within the morning.
I attempted turning WiFi off, after which the indicated battery degree increased from 49% to 51% in a single day, regardless of the machine not being plugged in! On this configuration, the pmset log signifies DarkWake occasions each two hours, which appears cheap.
The entire community visitors over a 24h interval is normally round 5 Mbyte, which is already quite a bit for a machine which sitting with its lid closed, byt I’ve seen one excessive of virtually 50 Mbyte!
The whole pmset log for one ARPT occasion appears to be like a follows. Throughout this era, there was community visitors with
- eu-north-courier-4.push-apple.com.akadns.internet:5223
- get-bx.g.aaplimg.com:443
- api.apple-cloudkit.fe.apple-dns.internet:443
(Sure, these knowledge have been captured final November, with an earlier macOS model, however the signs stay the identical at present.)
