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 shut down properly but as usual Apple is tight-lipped, and the cult members that moderate their community forum try to gaslight you into believing the computers are perfect and you're doing something wrong.

Eventually I just gave up and lugged the power adapter everywhere.

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.
