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 little thing 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” is ready to “energy adapter solely”.
What’s the laptop doing that’s so vital that it must occur all evening, with no one watching it?
pmset -g log reveals two sorts of DarkWake occasions: EC.RTC and EC.ARPT.
The RTC occasions occur often, 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 rationale (packet knowledge dump) given within the pmset log and snooped community site visitors, brought on by incoming packets on an already-established TCP connection on distant port 5223, distant host eu-north-courier-4.push-apple.com.akadns.web or any of a number of comparable domains.
log —present for the time round any of those occasions reveals 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 kind of EC.ARPT bursts, lasting one or two hours, round six o’clock within the morning.
The entire community site 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 just about 50 Mbyte!
The whole pmset log for one ARPT occasion seems a follows. Throughout this era, there was community site visitors with
- eu-north-courier-4.push-apple.com.akadns.web:5223
- get-bx.g.aaplimg.com:443
- api.apple-cloudkit.fe.apple-dns.web:443
(Sure, these knowledge have been captured final November, with an earlier macOS model, however the signs stay the identical immediately.)
