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.
