No I still don’t understand the Apple Watch battery issue.

I have a xaiomi mi band 9. The body to screen ratio is roughly the same as the Apple Watch. It does HR tracking, workouts, has excellent 1000 night brightness, weather, notifications etc. I get about 15 days from a charge. They say I can get 21. But either way. I understand the Apple Watch is running better hardware and more things in the background, but there’s also significantly more space in the watch for battery. It might be doing more but a factor of 15x is a crazy differential.

Comparing Apple Watch to Mi Band makes no sense. Apple Watch is more of a microcomputer than a cheap smart band. It would be better to compare it to something like Garmin Fenix 7X that lasts you almost 40 days with 120 hours in GPS mode and does much more than a Mi Band.

Calling it a "microcomputer" is meaningless.

What is it doing? Monitoring some sensors, communicating with a phone via bluetooth, running a screen.

Mi bands are low powered, low-feature and fairly miserable experiences if you interact much with the screen. They are great at no-effort tracking of fitness metrics and providing basic information.

Apple Watches are designed for much more interaction and variety of capability.

It can be hard to understand this if you haven’t used an Apple Watch.

You’re misinformed about the space for substantial additional battery. Look at any teardown to see the compact component fitting.

Your mi band is a great device; just be realistic about the tradeoffs. Other devices don’t have to suck for yours to be good.

(I’ve owned multiple Xiaomi and Apple devices.)
