Our device's batteries have a shorten lifespan as battery cycle count increases.

This was a problem with a small phones with tiny batteries.

Now, imagine a new Phone 13 Pro Max SKU that is 1" thick due to a 18,000mAh battery

As this battery is more than 4.13x larger then the 7 days of battery life I'm getting now can stretch out to 29 days.

Apple stipulated that after 500 cycles the battery will retail about 80% of its original capacity.

If this were to occur then the phone's battery would be good for nearly 40 years.

I'd personally be happy with a 9,000mAh so I'd only need to charge every half month

Most consumers would rather replace the battery once or twice over the typical 2-4 year smartphone replacement cycle.

Apple could double the number of battery cycles to 1,000 by limiting the charge capacity to 85%.

But consumers simply want the highest capacity in the smallest volume.

How does doubling battery capacity work if one only charged to 85%? ?

It would have a similar result - increased available cycles. That's why so many manufacturers recommend charging to 80 or 90%.
Just trying to understand the logic behind it. If charging to 85% doubled battery lifespan (not to be confused with daily use), why not set 85% as the new 100%?

Most consumers would prefer 500 cycles and replacing batteries every 2-3 years. The alternative would be 1,000 cycles and battery replacement every 3-4 years. Many consumers replace their smartphone every 2-3 years regardless.

Apple advertising 15 hours of video playback is also much more attractive than 12.75 hours.

Perhaps a lot of customers in the US upgrade early because of carrier deals, but not elsewhere. You really can’t expect one to upgrade their almost thousand dollar phone just because the ~$50 battery is not holding charge properly, right? Besides, there’s not much difference between iPhone X and iPhone 13, at least not from my standpoint. If I were to buy, I would buy newer model, but only to futureproof. It’s all diminishing returns at this point.

Brands would warn you that you have 10-20% charge left. Its either a subtle way of charge now to keep battery healthy or a more obvious warning that you better finish up whatever you're doing now before you get no more battery.

For me I'd love to to be able to charge every 1 or 2 weeks so a nearly 9,000mAh battery at 2x thickness to 15mm but under 350g would be awesome.

At the start of the phablet trend Apple was obsessed with ever thinner phones that resulted in the bendgate

The iPhone would be twice as heavy as it is now. People are already complaining the 13 Pro Max is too heavy as it is.

The answer is not necessary a bigger battery but rather better battery tech. Solid state batteries have 2.5x the density of Lithium Ion batteries, lighter, charge 4-6x faster and are safer as there is nothing in them that that is flammable.

Slightly bigger wouldn't be terrible in my opinion. Tooo big is an issue though.

Keep the battery in a overcharged state the majority of the time which 4.1-4.2 vdc (which is 100%) is not only harder on the battery it becomes more susceptible to damage from heat like leaving it in a vehicle. And most people charge their phone every night so it would be overcharged the majority of the time. Enough of this and it can wear faster than normal cycling in optimal conditions.

Reducing the max charge voltage isn't a solution to that because it would massively reduce capacity, you would have a large phone for no reason.

Another minor issue is drops. When an smartphone is drop tested the 3 main variables are height, how it lands (screen down, corner, etc) and weight. The battery being 3-4 times heavier "could" guarantee every uncased phone that slips out of someones hand will break.

Charging an 18,000 mah battery phone would be the deal breaker. Thats ~68wH @ 3.8 nominal volts DC. Standard USB wouldn't be able to charge it at all even if it could your looking at 18-20 hours minimum charge time accounting for efficiency losses. Even a 20w fast charger with same efficiency is 4-5 hours. So it would be to use a very inconvenient and not widespread MacBook charger. You wouldn't be able to charge it in a vehicle without a power inverter. And wireless charging is out of the question. A battery that size would cause people to go from charger to charger to charger throughout their day trying to get it to 100%. And while that isn't necessary its hard to ignore low battery even if it technically has more than a fully charged battery we have today....

This is what a 18,000 mAh Android phone would look like vs 3 stacked iPhones

I was filtering for phones with the highest mAh batteries and saw that 7,000mAh & 10,000mAh were the most popular capacity for a commercially available model.

So say an iPhone with more than 8,700mAh is very much possible at nearly 2x the thickness of 13 Pro Max?

I'd love to have nearly 2 weeks of battery.

Apple makes a ton of cash replacing worn out batteries and worn out batteries are the number one reason many people decide to buy a new iPhone instead of replacing the battery (stupid).
That being so - AplInc has zero incentive to put big long living batteries in iPhones (even though they’d be too heavy and thick anyway)

I don't think they do a lot of battery replacements. It's mostly the latter: making tons of money selling new phones to folks whose iPhones have worn-out batteries.

Mind, back in the 2-year contract days, replacing the phone for $199 made much more sense than trying to cajole Apple to replace the battery (which internal diagnostics still show 80+% despite dying pretty quickly) for $99.

Apple has a better margin selling more iPhones than replacement batteries.

Another benefit of thickening the iPhone for 2x more battery mAh would be more space for a larger image sensor & larger lens for better image quality.

A nearly 1.3cm iPhone would be awesome!

This may necessitate a new iPhone line called the iPhone Ultra that has a 7.2" display, is 13mm thick, has a 8,700mAh battery for nearly half month battery life. Fast charges at more than 30W to reach 0-50% charge in 29 mins and 0-100% charge in 119 mins.

Couple of years ago I was one of those who wanted an iPhone with all the latest and greatest hardware in the iPhone universe while still maintaining an insanely long battery life.

Today it is already a reality, namely the iPhone 13 Pro Max, which on a personal note, I am unable to drain out in a day, in spite of excessive usage.

I doubt many would want a thicker, heavier and more costly iPhone Max, purely for more standby time, especially when you consider that batteries do experience degradation over time even when they are not in use.
