Isn’t that rather a lot of current for what it is?
I didn’t read the datasheet but I imagine it has to have a lower power mode than that. Much larger MCUs can manage an average power consumption far lower and power off the same battery for periods measured in years, not days.
This is simple enough you’d think you’d be able to power it off an EM field directly!
I can't be bothered running the datasheet through a translator but there seem to be sleep modes at 2.5uA and 200nA.
On my end, having never really cooked, everything is an effort. I have no inspiration on what to buy, no inspiration on what to cook from what I bought, and whenever I actually do the cooking, everything has to be a mental focus. I can't just "bake" stuff, because I have to focus on checking it's baking okay, turning it, shaking it.
Now I have no doubt all of this can be much smoother and enjoyable, but only if you invest enough time that each step is no requiring you to spend hours checking recipes ideas, baking tutorials, etc.
I was lucky(?) to grow up with a great cook and gardener for a mum, so I'm not even really sure how you exist without doing this at least. Pardon my naivety, but what do you eat...? Is everything unwrapped from plastic or from the local takeaway joint?
