What's your harmless/low-stakes conspiracy theory?
What's your harmless/low-stakes conspiracy theory?
I’m surprised as fuck those guys are standing out there again. I didn’t see them in Denver much for like 10 years but now they are back. Brave young men or men who are very confident in their running speed.
More power to them, I asked a group how much they usually got and they said $25/hr but I think they were padding it in case I was actually going to hire them so I’d figure the going rate is probably $20.
Corn meal, egg, salt+pepper. Add water until self-supporting balls can be formed. Drop 30mm balls into hot grease.
Like that?
1375.99 Pesos
¡¡¡LLAME AHORA!!!
Tooth fish doesn’t sound very appetizing, does it?
If we turned all of global beef demand into grass-fed, we’d literally decimate our output because there’s not enough grazable land.
Even land categorized as agriculturally grazable is often not realistically grazable (think mountains, etc)
Fun fact: the Native Americans that originally created the various and sundry types of corn that we have called themselves, “Walking Maize People.” We’ve analyzed their bones and found that the specific type of carbon that corn “tags” as its own ion, made up about 30-40% of the carbon in their bones, and presumably their bodies.
Due to the fact that corn is added to almost everything that is in the US food chain, when similar analysis has been done to average US citizens, more like 60-70% of the carbon in our bodies comes from corn. We “paint” fruits and veggies with corn, we add corn as sugar to all soda, we add corn to some breads for no reason. We, the citizens of the US, are walking corn.
The battery has a capacity reading down to the milivolts and the phone knows how much power it is using, which changes dynamically to meet the usage. The remaining battery level is determined by the voltage available at the current consumption. There is some averaging involved based on your usage profile.
So your battery level is accurate at a given time, but changes based on what you are doing and what you have running. So your battery will drain faster if you are playing an intensive game, but will last far longer if you have nothing unessential running and the screen is in sleep mode.
Apps like Facebook, chew through battery in the background because of how often it has to use resources to check for notifications, when when you don’t actually have the app open or in the recent apps list. So your battery will lose charge faster than you would expect when you haven’t been on your phone.
so, naw lil bro.
The remaining battery level is determined by the voltage available at the current consumption
Gets all condescending about how it works
Isn’t aware of the difference between V and mAh or the extremely horizontal (for most of the range) curve defining the relationship between them for Li-ion batteries
I got irritated enough by people spouting off at me to look up how it actually works, it’s not at all how you are describing, although describing it as “bullshit” is probably a stretch
So naw big bro
The battery has a driver, which is written in software that indicates level based on an underlying profile of how the battery drains.
Hence why Pixel4a users were suddenly shocked by an upgrade that halved their battery life because Google made a whoopsie on the battery profile.
We are saying the same thing, I was oversimplifying though.
The profile is based on the voltage of the battery, the capacity, and the permissible amp draw. The actual voltage reading informs the device of the real remaining capacity because the device can’t read capacity and can only infer it based on historic data compared against the profile. Battery temperature is also a throttling factor, but we don’t need to get that far into the battery management weeds.
I don’t think I am going to take confident proclamations about how it works from someone who thinks “voltage” translates to “how much energy is left in the battery”.

I don’t really know how this stuff works, that’s why it is my conspiracy theory instead of me just giving fun facts. But, I don’t think you know how this stuff works either.
It sounds like coulomb counting (current sensors, as you said) is often the method. Personally, I suspect there’s a decent amount of bullshit inserted into that to make it look “normal” when people are looking at how the number behaves, at the expense of accuracy. You might move your phone from cold to warm for example, and the usable energy in the battery might increase when that happens (or something) but it’s definitely not going to show your battery percent going up, even if it could detect it properly which I don’t think it can. Whether to say that means it’s “bullshit” is I guess a matter of opinion.
Phones don’t use lead acid batteries, genius. I don’t know why you think that study is relevant.
Also, your phone knows what the temperature of the battery is, and almost certainly takes that into account, although this affects the output voltage but not the amount of energy stored.
Li-ion is worse. I looked up a few different articles, I just kind of picked that one at random because I didn’t want to spend more time on it. This one is pretty succinct about it:
pcbway.com/…/Important_Techniques_for_Determining…
“This method is not suitable for some other cell chemistries like lithium-ion, which has a negligible change in its voltage throughout most of its charge/discharge cycle.”
My new conspiracy theory is that a gang of people have teamed up to try to wind me up on this particular topic in what was supposed to be a lighthearted nonsense-question to which I gave an appropriate nonsense-answer.
You’re the only one who actually did arrive at something which is pretty much the actual answer (“coulomb counting”), although you keep mucking it up by saying things like you “can get a voltage sensor” to get the energy left in the battery, or “current through the battery” when the battery is the only part current does not flow through during discharge, or by making up wild random guesses that something is “almost certainly” taken into account. Just take all that extra stuff away and stick with “the phone monitors discharge” and you’ll be pretty much right.
Hopefully we can put this whole endeavor behind us now, and go back to talking about Chipotle and chemtrails.
Preach sibling
Idk how multiple super assertive people all got the idea that “voltage = battery percent” and all wanted to yell it at me the same time lol
It tries but the value is floating until it actually has a full charge cycle. There is no way to know what the entire voltage range is. You’re getting into how efficient the chemistry is over time and that is impossible to measure. It can be estimated, but that is all theoretical and not real. When the battery is fully discharged, the time, temperature, and current can be used to determine Coulombs and that is the actual energy capacity.
I’m not an expert, but I have built many circuits. My main experience here is in reverse engineering some gaming hardware that had an advanced battery management chip from Diode Semiconductors. That had such a Coulomb battery meter. The board was a 3 layer PCB and I took that as a challenge. The batman chip was also a small ball grid array (pins are inaccessible on the back side. I didn’t have xrays when I did the first trace of all pins, so I had to fully understand the chip to trace all connections only using the vias. I think I have a chip or two in parts drawers that do the same thing, but I never built anything with them, or at least haven’t yet.
