I get the lacking Linux support, but what about Windows? Most serious work happens on Windows and their SoCs seem to have much better support there.

Apple's hardware+software design combo is nice for things like power efficiency, but so in my experience so far, a Macbook and a similarly priced Windows laptop seems to be about equal in terms of weird OS bugs and actually getting work done.

I’m getting about 2 hours with current macos on an arm macbook pro. I used to get 4-5 last year.

This is out of the box. With obvious fixes like ripping busted background services out, it gets more than a day. There’s no way normal users are going to fire up console.app and start copy pasting “nuke random apple service” commands from “is this a virus?” forums into their terminal.

Apple needs to fix their QA. I’ve never seen power management this bad under Linux.

It’s roughly on par with noughties windows laptops loaded with corporate crapware.

That's unfortunate, perhaps your particular macbook is having a hardware problem?

As a point of comparison, I daily two ARM macs (work M4 14 + personal M3 14), and I get far better battery life than that (at least 8 hours of "normal" active use on both). Also, antidotally, the legion of engineers at my office with macs are not seeing battery life issues either.

That said, I have yet to encounter anyone who is in love with macOS Tahoe and it's version of Liquid Glass.

The current issue is iOS 26.1’s wallpaper renderer crashes in a tight loop if the default wallpaper isn’t installed. It isn’t under Xcode.

I have macos crash reporting turned off, but crashreport pins the CPU for a few minutes on each ios wallpaper renderer crash. I always have the iOS simulator open, so two hours battery, max.

I killed crashreport and it spun the cpu on some other thing.

In macos 25, there’s no throttle for mds (spotlight), and running builds at a normal developer pace produces about 10x more indexing churn than the Apple silicon can handle.

On my iPhone, even though I'm not on the latest "upgrade" (I made sure to avoid the Liquid Glass crap), the widgets just refuse to update most of the time. I have to tap them to get an update. Which completely defeat the purpose of having widgets in the first place. I am tempted to do a full reinstall from scratch but I think I'll just wait and bite the bullet for some Android in the near future. Apple software just isn't reliable at all, it makes the expensive hardware largely pointless.

I run an old T480 with FreeBSD and get about 17 hours of battery out of it. Sure, it’s a bit thicker but gets the job done as a daily driver.

[speakspokespok]

There is literally no way. Spill the beans!

[rootnod3]

Sorry, thought I had posted, but didn't get through. It's a T480 with the 72Wh and the 24Wh battery running on FreeBSD. Screen has also been replaced with a low power usage screen which helps a lot in saving battery while still giving good brightness.

Most of the time I am running StumpWM with Emacs on one workspace and Nyxt in another. So just browsing and coding mostly.

OpenBSD gets close, but FreeBSD got a slight edge battery wise. To be fair, that is on an old CPU that still has homogenous cores. More modern CPUs can probably benefit from a more heterogenous scheduler.

[rjsteixeira]

Probably has the extra big battery. Thinkpads have options for different sized batteries.

Or they just got one of the 'good' models and tuned linux a bit. I have a couple lenovo's and its hit/miss, but my 'good' machine has an AMD which after a bit of tuning idles with the screen on at 2-3W, and with light editing/browsing/etc is about 5W. With the 72Wh battery that is >14h, maybe over 20 if I was just reading documentation. Of course its only 4-5 if i'm running a lot of heavy compile/VMs unless I throttle them, in which case its easy over 8h.

One of my 'bad' machines is more like 10-100W and i'm lucky to get two hours.

Smaller efficient CPU + low power sleep + not a lot of background activity + big battery = very long run times.

[KerbalNo15]

!!! I can get my laptop to 7.5W under web browsing with powertop tuning, but not 5. What did you do?

[rootnod3]

72Wh + 24Wh battery (one swappable one internal) and running FreeBSD Current.
