And yet longer run times equate to fewer cycles

 The problem with you zealots is you don't understand basic math.
Fewer cycles don't matter if the battery can't handle as many cycles.
 There's a reason iPhone batteries need to be replaced more often, JR.
Apple iPhones start with el cheapo laughably puny substandard batteries.
 And there's a reason the EU forced Apple to disclose the battery life too.
Notice how pitifully short that disclosed Apple iPhone battery life is.
 Why do you think Apple's disclosures shows pitifully few charge cycles?
The most critical determinant of overall battery life, is initial capacity.
 How long a battery lasts per day is DIFFERENT than the battery's lifetime
because any given battery has a DIFFERENT number of charge cycles in it.
 None of your zealot arguments takes into account Apple's deplorable lack of
batteries being able to handle the charge cycles that Android batteries do.
 Remember, nobody replaces more batteries yearly than does Apple.
The REASON for Apple's deplorable lack of charge cycles is the capacity.
 What nospam used to claim was Apple's well advertised "vaunted efficiency".
 However, Apple's admirable 1% to 2% increase in efficiency can never make
up for a 200% decrease in battery capacity, no matter what math you use.
 The most critical determinant of overall battery life, is initial capacity.
No amount of slick Apple MARKETING can overcome its lack of charge cycles.

REALLY? Can you support that with facts, not unsupported words. Your words are total bullshit. I'll bet you don't read a word of what follows.
Here are some facts:

Quotes:
"Battery Capacity
The battery capacity, measured in milliamp hours (mAh), gives a basic indicator of how much juice a phone’s battery can hold. However, optimization plays a huge role in translating that raw capacity into real-world usage.
Recent iPhone models have packed in these mAh capacities:
iPhone 14 Pro Max: 4,323 mAh
iPhone 14 Plus: 4,325 mAh
iPhone 14: 3,279 mAh
For Android, flagship capacities include:
Samsung Galaxy S22 Ultra: 5,000 mAh
Google Pixel 7 Pro: 5,000 mAh
OnePlus 10T: 4,800 mAh
On paper, higher-end Android phones edge out iPhones on battery capacities. The iPhone 14 Pro Max packs fairly large batteries given its more compact size. However, Apple’s custom silicon helps enable power efficiency that closes the usage gap despite lower mAh ratings. Still, Android makers continue pushing the envelope on sheer battery size to enable marathon usage times."
"Real-World Battery Life Tests
Lab tests of battery life provide useful comparisons between iPhones and Android phones under controlled conditions. Reviewers like PhoneBuff run battery rundown tests for different use cases. In a web browsing test over 5G networks, the iPhone 14 Pro Max lasted actively for 11 hours 28 minutes, and on standby for 16 hours making it a total of 27 hours 38 minutes. On the other hand, Galaxy S22 Ultra was active for 9 hours 16 minutes, and on standby for 16 hours, making it a total of 25 hours 16 minutes. Clearly, real-world testing indicates iPhones have an advantage for typical daily use, thanks to the platform’s power efficiency along with battery capacity. However, results can vary depending on the individual models tested in each phone generation."
Other tests show iPhones and Android about the same.
Here's the clincher:
"Battery Life Over Time
How well a smartphone battery holds up and maintains its charging capacity over an extended period is an important consideration for long-term owners.
Overall, iPhones tend to experience less severe battery degradation than typical Android phones after 12-24 months of use. Reports indicate most recent iPhone models still have around 80-85% of their original capacity after two years. Though there is no way to determine battery health on Android, but using 3rd party apps like AccuBattery, it has been seen that many Android phones dip below 70% capacity by the same point as repeated fast charging takes a toll.
However, Android variety means experiences vary. Since there are numerous brands, ways to check battery health on Android also varies. Since Android 13, Google started to offer battery health count from settings. Although smartphone brands are offering quality batteries, after a couple of years things like less battery backup and battery swelling happen in Android. On the other hand, there is no record of iPhone battery swelling.
This happens because of the extra fast charging facility. Fast charging the phone every day has an adverse effect on the battery. Currently, brands offering 65-watt, 85-watt, and even 120-watt adapters on Android have a high chance of battery damage. iPhones on the other hand are quite careful with their charging accessories. That’s why they don’t offer anything extra other than suitable charging power."
