This used to happen to my MacBook Pro, although it was a non Apple Silicon one. The issue was that I had changed the DHCP lease time on my router from the default to a really low value. I believe I had set it to 15 minutes. What I believe was happening was the MBP was waking up to renew its IP address every 15 minutes and by the time it went to sleep again, it was probably waking back up to repeat the process. Changi…

I like low lease times. DHCP server knows what's really on the network, and if something requests lots and lots of the pool you'll be fine in 15-30 minutes.

If things are set to a really long time, >=12 hours, you find out the next day when everything is broken (or you get alerts in the middle of the night). If you set them to a randomized 15-90m span, you get things breaking immediately when you screw up the dhcp server.

Apple's power management isn't as great as everyone claims. I've an older MacBook Air with a severe battery drain problem. The battery will last maybe a day or two when SHUT DOWN (not sleep) before being fully drained and refuses to power on. It's done this since day one. I tried resetting everything possible which could be reset and nothing helped. Allegedly the problem is related to a Bluetooth radio which does not…

I haven't used a MacBook in years but when I did, their power management was actually the worst thing about them - this was before they moved to ARM, so I assume it has improved, but it was common for a MacBook pro to turn into a screaming hot chunk of aluminum which would burn your legs on contact and misrepresent the actual battery life available to it.

My biggest issue with pre-arm macs is that on the highest end models (issued Core i9 from my job), it would thermal throttle to the point it was nearly useless when I needed it the most. It was really locked down, so I couldn't do anything to undervolt/underclock it, which would have made it run much better.

That is so weird. How much mAh can a single “wake and renew lease” possibly take? Like it has to be milliamp-milliseconds (mAmS?). I mean my phone is chattering with the cell network probably all the time even in a fairly deep sleep mode. The laptop is lighting up the WiFi stack to send and receive (and process) like a few packets? Like you said though, it’s pre Apple silicon so who really knows! Maybe it decided to…

It may stay on longer than the amount of time it takes to renew. Perhaps for every wake it stays on for 60 seconds; it is also doing other things like checking mail.

I wonder if some user-space process lights up and throws a wrench in things.

I’m sure both Microsoft and Apple have entire teams with incredibly full backlogs dealing with power management. And I’m sure half their time is spent dealing with “messes” caused by other teams doing wild and crazy (but somehow theoretically useful) shit.

It’s clearly not an easy problem.

Imagine people who are not technical buying a new mac because of this...

What if, hear me out, that’s kind of the goal? It’s not the only trap in the Apple ecosystem that degrades your experience over time. I’m convinced that the main purpose of Podcasts app is to eat up storage.

Hah. Your answer just has more questions. What on earth is requesting so many DHCP leases?

I have been experiencing this issue, I think it's related to bluetooth, which does appear to be flaky

I have the same issue and it's driving me crazy. One bluetooth device is waking up a MBP M4 regularly during the night, lighting up an external screen. Even without any connected devices.

Conversely, I have a joystick that prevents my Windows desktop from sleeping; thankfully it won't wake it up if I manually sleep it.

Badly behaving peripherals suck.

I’ve been facing a similar issue with my MacBook Pro with Apple Silicon.

While sleeping with an SSD connected, it seems to wake up periodically and activate the drive to do something. The result? Both the laptop and the SSD eventually overheat, and the battery quickly drains.

The only way I managed to mitigate this issue is by disconnecting all drives and plugging in the MBP before setting it to sleep. It’s an annoying bug, to say the least. It reeks of insufficient quality control and testing…
