alt Hacker News> You're going to use your devices, so you won't control the temperature or, largely, the charge percentage.
> I think good advice is to keep your devices as cool as you can (...), and keep the battery between 20% and 80% as much as possible.
Yeah that's kinda what I meant. Where it's easy or possible to do so (for eg lots of modern laptops & phones allow charge limits), it's better to follow these guidelines.
> Batteries are ultimately consumables, so don't stress too much. Just care for them as much as convenient, and that's it.
Yeah I agree (and that's what I meant by my last sentence), however, a lot of people (including eg my dad!) end up having battery issues while being unaware that they can do things to protect their hardware.
For example, my phone has enough capacity to last the whole day even at 60% of it's capacity. I've set it to stop charging at 80% (the lowest possible SOC) for this reason. On my laptop, I frequently reduce it to 60% as I use it plugged in.
> I don't think this advice is useful.
I'm afraid I don't get what's not helpful? We're probably talking across each other.
It came across to me as "keep your batteries always under 0 C", which obviously almost nobody can do, and it leads to a sense of "eh, I won't go to these lengths, might as well do nothing", which is counterproductive.
I see the same reaction with healthy eating, where people are so put off by extremely militant advice that they think "I can't eat only vegetables all day, fuck it, I'll eat these three cheeseburgers".
I agree with your second comment, the first one just could be misconstrued as very hard-to-follow advice.
