Coming soon, they will unveil the Huawei xxMatexx XTX Pro X design.

Lol, you literally quoted me, didn't actually read what you quotes, and then did something completely different.

Do you know that battery life ≠ battery capacity? That is not the same measurement as I have already tried to teach you 3 times.

Please state the calculation that you would use to "determine how often you have to recharge" that is valid for Wh and not for Ah.

What is its idle power draw? What is its power draw under load? Playing video? Sleep mode? That source gives nothing which determines battery life. All it gives is a nearly useless capacity number, just like all other manufacturers. So not valid at all. You still have exactly 0 more information about battery life.

If I am wrong, please state your calculations of what the battery life is with that 54Wh battery.

Your entire argument was "Ah is useless and Wh gives consumers the information to determine battery life" So go ahead, determine the battery life.

How is this any different at all if they said that it is a 5.8Ah battery? They don't give any current or power draw.

As an exercise:

can you tell me the battery life difference between an arbitrary Laptop A with a 54Wh battery and Laptop B with a 27Wh battery?

Please explain to me what the difference is between battery life if you have a 5000mAh battery and an 18Wh battery.

Please state the calculation that you would use to "determine how often you have to recharge" that is valid for Wh and not for Ah. I am all for it. If you can cite a single source where the manufacturer gives a specification that would give battery life in Wh, and not in Ah, I will concede the entire argument and say that you were right the whole time in every comment make a note that you were right. Please show your calculation work.

The thing is, it does not matter how much charge the battery holds, it does matter how much energy it holds. Without knowing the Voltage the Ah is useless.

This is patently, objectively misinformation and completely false. That is a direct quote of your words, today. That was your last comment. I have already laid out multiple examples of how Ah is a useful measurement and what you can do with it. Therefore, it is misinformation. It is not disinformation, but stating untrue things as fact is misinformation, even if you have no idea you are wrong.

Sorry, but you are simply wrong. Simple math says that you are wrong.

You can buck or boost convert nearly any voltage to any other voltage.

Then measure the current output of the battery, boom you have battery life.

Also electrical charge can be used in many, many very valuable calculations without involving voltage at all.

Let's take an arbitrary example with an arbitrary battery powered device. Let's say the battery is somewhere between 1V and 10000000V. You can't measure it because you might blow up your multimeter.

You know that the battery is 5000mAh. You can safely measure that all of the circuitry is draining 1000mA because sense resistors or contactless magnetic current measurements don't have anywhere near dangerous voltages. You know that the battery will last about 5 hours. What is the voltage? Doesn't matter.

Yes, charge and the flow of charge is not the entire story, but to say it is useless or does not matter is just a straight lie. It is fine if you don't understand electronics, but then don't spit out misinformation.

Yes Watt-hours would give a more complete picture to slightly tech-inclined consumers (makes 0 difference for 99% of consumers), but then it returns to not mattering because you can do the 5s calculation yourself because single cell lithium batteries are overwhelmingly 1 nominal voltage.

Literally 90% of calculations related to efficiency are JUST as valid using mA as W.

Your device uses 12mA at idle with a 5000mAh battery has the same relevance as your 18.5Wh battery using 45mW at idle.

I believe it actually has to do more with historical conventions in electronics or math. (This is just what I remember from heresay when I was in university as an electronics engineer), but there is also a mathematical reason.

history hearsay theory

The easiest way to measure power draw is by measuring current draw (voltage across a sense resistor) way back before there were affordable, quality ICs to measure voltage and current and pretty much joule count.

To add to this, current sensors are much easier and cheaper than test machines that do the calculations for you.

When lithium batteries and NiCAD batteries became standard compared to the earlier lead-acid (which are measured in Wh), they had an extremely flat voltage curve compared to lead acid. They could be considered to be at a constant voltage.

Now cheaper electronics were being made and if a designer wanted to know how long a battery would last, they could take the nominal battery voltage that the battery would be at a vast majority of the time, and they could just measure the current draw over a short time of the circuit, 10s of calculations, and you have your approximate battery life. There is a joke that engineers approximate π to 3.

Even designing electronics today, everything is specced to current draw, not power draw. ICs take X current in mA during Y operations. Your DCDC converters have Z quiescent currents and from there you can calculate efficiency. It is much easier to work in current for energy running through the circuit.

Math units

Ah is a measure of electrical charge.

Wh is a measure of energy

Batteries and capacitors hold charge so are measured in Ah, generators that power the grid generate energy and use of that energy is measured in Wh (it also isn't a "constant" voltage source like batteries as it is AC)

But piracy is a product of their free market, don't they want their mythical free market to be a free market?

Or maybe that was always just bullshit and they rely on using their money to suppress competition while they deliver a terrible, inferior product.

OK that is fair, though that is not self hosted...

VPS machines are a completely different beast than self hosting. But I guess I only said home use, not specifically self-hosting though we are in a self-hosted community. There are 1000 guides for setting up a VPN on your home network.

To be fair, if something is open by default or very easy to enable without informing about the risks, tons of people will have it exposed without thinking.

It isn't that "tons of people do it so it is normal and perfectly fine" but more "people don't realize." It also uses some nontrivial amount of resources to process and block those attempts, even if they never have a chance of getting in.

There is yet a reason I can find to have it forwarded for home use. Need to ssh into a machine to fix it? VPN.

There are plenty of secure web-based tools to manage your server without a VPN also.

Google keep used to (don't use it anymore) store your notes "backed up" by email. You could view all your notes in gmail.

Maybe it was something like that?

Yes, I agree with you. The argument that "we don't want devices to require internet access" is very strange to me for this update of the standard.

This has absolutely no bearing on whether devices will be enshittified and require online cloud accounts/functionality/etc.. This is not affecting the standard of devices saying they require internet access...

This literally changes nothing except creating a standard path and manner of connecting devices to the internet. Do people know what a standard, regulated path for unwanted features means? A standard one-size-fits-all manner for blocking cloud access for all devices!

He means weeks, not days

Sadly it doesn't work almost at all with the *arr suite even with flaresolverr.

I have had to move mainly to the small private tracker and knaben because torrentgalaxy and 1337x both stopped working in prowlarr because they had to up their bot fighting game...
