The vast majority of cell phones use a single-cell Li-Ion battery, so their capacities can be directly compared using mAh. Laptops almost always contain multi-cell Li-Ion batteries, so their capacity cannot be directly compared using mAh (e.g. a 4S battery rated for 2500mAh has more energy than a 3S battery rated for 3000mAh).

So why don't we use Wh for phones too? Simply because manufacturers would rather advertise a battery size of five thousand mAh (wow, so much capacity!) instead of 19 Wh.

The same issue happens with portable USB battery packs - they're all advertised in mAh even though they use a wide variety of chemistries and cell configurations internally. What manufacturers do is take the total Wh of the pack and convert it back to the equivalent mAh of a single-cell Li-Ion. It's annoying, and I really wish they would just use Wh directly.

Can I subscribe to more badger facts?

You might be lactose intolerant, in which case taking lactase enzyme pills immediately before eating may relieve your discomfort.

idk why, but I dug around YouTube for an hour or so to try and find that alarm for you. I stumbled across one that's so close to your description, though it's from a BlackBerry, not a Samsung:

Is this the one?

I wish people would learn and use the ISO 3166 codes for their area. For example, US-DC, GB-LND, AU-ACT, etc. Unambiguous, easy to look up, short to write, etc. Just takes a super quick search. I know it'll never happen, but standards are great!

The problem is that international travel simply doesn't make sense for many Americans. The U.S. only has two international borders - Mexico and Canada. Any other international destination is going to be a flight across an ocean (South America isn't, obviously, but the distances/costs are similar), which can be $400-$1200 per person. The cost/duration of flights and need to adjust to a dramatically different timezone means that it really only makes sense to travel internationally when you can go for at least a week at a time. However, Americans tend to have very limited paid time off - usually only 10-20 days or so per year - and that is often a combined pool for vacation, sick time, etc. This means that a single international trip can chew up over half of the PTO for the entire year. So even if you can afford to travel, you don't have enough time off anyway. Most of the time it makes much more sense to travel domestically and just take Thu/Fri off for a long weekend.

(This is speaking from experience, if you couldn't tell, lol)

Can someone explain to me why they might have gone with this strange pricing model instead of the very simple revenue sharing model that Epic uses?

Could you give a brief overview (or detailed if you want, I'm curious!) of what you think makes a good process? More specifically, what makes a good process and what makes good documentation for said process?

That would be ideal, but I think at this point there's just too much marketing momentum using mAh, and switching to mWh would be too confusing to consumers. But yeah, I agree, mWh is definitely the most appropriate unit to use.

The main problem with lithium ion battery fires is that the reaction is self-oxidizing, so you can't put it out by just smothering it. You actually need to cool them down enough so that they don't re-ignite. Plus, once they're damaged, even if you do cool them down enough they're much more likely to short and re-ignite themselves again anyway.

Consider the "fire triangle" - fire needs three things: fuel, oxygen, and heat. With, for example, gasoline fires you can take away either oxygen OR heat to extinguish them, but with lithium-ion battery fires you have to take away the heat to extinguish them.

Batteries often have a rating like 3250mAh, which is arguably clearer than 3.25Ah, especially on a datasheet.

Police have to detain someone to breathalyze them. Detainment simply means that the individual is legally required to stay there, that's it. If you get pulled over, you're implictly being detained.

"Based" is typically used to describe someone who says/does something without caring if they'll be judged for it. Most commonly, it's shorthand for "That's a controversial opinion and you are bold for saying it, but I agree with you." It turns the previous sentence into an adjective, which is a little weird but it makes sense eventually.

So if I had to choose a single word as a synonym, I would say "Bold".

Nah, but now I have a new artist to check out, thanks!

Well, FWIW, ISO 3166's full name is Codes for the representation of names of countries and their subdivisions. "ISO 3166" is just easier to type and refer to.

Though GUAC would be a great acronym, lol.

Sorry, I basically combined two separate thoughts in a weird way. First, I meant that the raw battery cells themselves are usually rated in mAh on their datasheets, so manufacturers simply kept using that unit on their marketing material. Second, I meant that datasheets usually use mAh because it is a more appropriate unit than Ah for comparing cells of that approximate size. This is somewhat common in engineering documents - you will often see measurements written as 20.0mm instead of 2.0cm (usually because it is more consistent with the rest of the documentation). In this case it's because many of the Li-Ion cells used in phones will have their charge/discharge ratings in mA, so it makes sense to have the capacities in the corresponding mAh.

But I do agree, on marketing material it makes much more sense to just write the capacity in Ah (or better, Wh). Using mAh just because it's a bigger number is plain silly.

I'm probably going to end up back on Reddit to some extent, but I think Lemmy will stay in my rotation of stuff I open when I'm bored. Or until they inevitably kill old.reddit.com, then I'll be outta there for good...

I dunno, I didn't put much thought into it, sorry ¯_(ツ)_/¯
