I am.
It is not.
Which part of it's not £79 are you failing to understand?
Apple never stated it was a two hour job. They gave me a two hour window while I did my Christmas shopping. It's a customer service convention. We did the same at PC World when performing in store upgrades and repairs when I worked there 20+ years ago. Let the customer go do something else, so they're not stood there getting impatient.
It was £79.
Just because apple got busted and have reduced it to £25 as a bribe, doesn't mean apple were never selling this overpriced battery for at least 8 times more than its value.
Not when you posted that. Price dropped on 28th December.

That is correct. But it doesn't refute anything. The fact remains it was £79 up until the media hoohar. It's only been reduced to £25 as a bribe because people didn't like their iphone being slowed down.
Funny you should say that. I'm on the phone to Apple now and they're refunding the difference.
The repair infrastructure, technicians & bricks and mortar stores all cost £0?

It’s a bit like giving away bumpers and cases with the iPhone 4. It shuts the whiners up.
You can still get your iphone battery replaced at a brick and mortar independent phone shop for £25 for the past decade, Not just since the hoohar. You're just coming up with strawmen now.
Ah yes, I forgot, slapping the apple logo on some chemically indistinguishable lithium-ions suddenly increases the value of them by £54.
I totally forgot. Sorry.

The dual-batteries in the iPhone X haven't changed the voltage; it's 3.81v (compared to 3.82v in the 6S, 3.82v in the 7 and for reference, 3.85v in the Galaxy S8, 3.85v in the Pixel 2 XL, 3.82v in the Mate 10 Pro).
The problem is that most people don't know what goes on with batteries, how they work, when happens when they are degraded and basic principles of electronics.
The issue is not the battery is not at the correct voltage it really isn't that simple, its they can't supply enough power when they are degraded. On a DC circuit power (W) = Volts x Amps.
The voltage on a battery isn't constant and it will vary depending on how charged it is. A fully charged 3.85V Li-ion battery will probally actually read closer to 4.4V, a fully discharged one will be around 3V. Battery life % use a measure of the voltage to determine how much capacity is left.
Also the amount of current (Amps) a cell can supply isn't constant through the entire capacity of the battery. The amount of Amps it can supply gets lower as the state of charge gets lower.
Same thing with charging, the lower the state of charge the more Amps it can take, the higher the state of charge the less it can take. This is why you often see quick charge figures for 0-80% not 0-100, that last 20% takes a long time.
Just because the battery is degraded doesn't mean it's not at the correct voltage. The voltage is probably is fine as the phone is reading say 30% and will measure 100%-0% correctly.
What happens when a phone shuts of at 30% is:
The phone has 30% of its battery left, but at 30% the amount of power a degraded cell can supply is less than the phone can draw. As soon as you put a big load on the degraded cell, it can't supply the power and the phone turns off. If the load was reduced the phone would stay on until the battery got to 0% which is what Apple have done.
The reason they turn off is because of the inbuilt protection circuits that are there for your safety so it basically doesn't self combust in you're hand.
Same thing happens when your PSU can't supply enough power for your PC, it will probably gets you into windows fine but as soon as you run anything demanding like a benchmark it turns off.

So how do you get a battery to maintain that power?
And how do other smart phone manufacturers manage it without shutting off at 30%?

From what I've seen even a throttled iPhone 6S benchmarks higher in single threaded performance than a snapdragon 835, so I wonder if it's simply because other manufacturers use slower, less power hungry CPUs?
They don't, even a quick google confirms that. Old phones shutting off at 30% isn't new not an exclusive to Apple thing, especially with powerful modern SOC's. They are great at sipping the watts at idle but peek power draw is very high compared to yesteryear. Its not just the SOC's, screens, cameras flashes and big stereo speakers etc. are all more power hungry. Battery tech hasn't moved on much at all.
You have to minimise degradation by having:
A smaller usable capacity (bigger buffer at the top and bottom)
Bigger Battery to compensate for the above
Slower charging
Slower discharging
Proper thermal management.
None of the above the mass market will tolerate. Joe blogs doesn't want a think phone, they want something with a sleek design and looks cool for example the Motorola Razor. It was a rubbish phone compared to the competition and enthusiasts shunned it but sold by the bucket load because it looked cool. Everyone wants their phone to charge in a few minutes, hence things like Qualcomm quick charge, what they don't tell you is they increase degradation. Everyone wants phones with big bright screens, big bright camera flashes and a powerful processor so the last one is out. You can't do proper thermal management on something the size of a phone like you can an EV.
Look how many sales the Galaxy S Active model gets compared to the regular. It's a thicker phone with a huge battery and doesn't break when you drop it yet I have never actually seen one in person because no one wants it....
Many don't. A google search for "phone switches off at 30% battery" produces many results and when I did that a couple of days ago, the only result on the first two pages mentioning iPhones was the announcement from Apple.
This symptom isn't exclusive to Apple, it's just that they appear to be the only ones we who have addressed it in this way. My problem is the way they've handled it without actually telling anyone what they've done. I understand battery technology and how it works and b0rn2sk8 has described it very well above.
Apple should have announced this previously and iOS should have told people what it was doing.
This.
I will defend Apple against comments that are just incorrect, the solution they put in place is elegant but the way they went about it was 100% wrong.
