How's the battery life on these Casios with fancy features?

My ideal smart (dumb) watch has step/heart/sleep tracking synced to my phone, no other connected features (especially no notifications), and a ~month of battery life. Currently that only satisfied by a Withings Scan Watch or a few Garmin models with the notifications disabled...

Amazfit Bip has you covered, you can disable notifications, you can buy used one for <20USD and they still last one month + they are perfectly readable in sunlight thanks to MIP display, I'm on my 3rd now

there is nothing better since Amazfit Bip, Casio came close, but they are too bulky

My ideal watch also has: mobile voice & data connection (via eSim), speaker and microphone, camera.

Those in addition to what it already has: 1 month battery life, HR and SpO2 tracking, flashlight.

Also, blood glocose and BHB monitoring would be nice.

And I didn't mention the software..

Garmin Instinct 3 Solar, very close to 30 days for me. YMMV depending on how much sun you get

It seems that the battery lasts 35 hours with heart rate tracking, 1 month with no HR, and 11 months with power saving.

    Run Time

    Using activity functions (heart rate): Approx. 35 hours max. 
    Using in watch mode with heart rate measurement OFF: Approx. 1 month
    Using with power-saving function ON: Approx. 11 months

I'm not sure how well the "solar charging" feature works, though. It's surprising that it does not last longer than Fitbit or Garmin.

Take a look at the Amazfit NEO. I use it with all the notifications off.

Very poor. Hardly lasts a week with step tracking and heart rate enabled. Like someone else mentioned, go for a Garmin instinct 2 or 3 solar. My 2 Solar lasts more than 30 days on a full charge.

36ish hours a charge w/ HR stuff enabled.

Yet, my 10+ years old pebble 2 HR lasts a week, and the new pebble time 2 claims up to a month.

[swiftcoder]

Yeah, 36 hours is honestly pretty disappointing. The old Withings ScanWatch easily ran >2 weeks with HR and notifications enabled, I'd have expected similar performance from the Casio.
