I have the 2020 13" M1 MBP. Currently the battery is 94% so not the biggest issue but how low do you let it go before you replace it? What's the cost and process?
 
I don't replace it, because by the time the capacity decreased to an unusable level, Apple had already stopped the software support for the product.

The only time I replace the battery is due to a problem that caused spontaneous shutdowns. By referring to a guide on iFixit website, I spend 30 minutes of my time. Your cost may vary because of purchasing power.

I haven't replaced my battery yet, but it's getting close to that point—I'm at 87% battery health at 390 cycles. Generally, Apple advises you to replace the battery when it his 1000 cycles or 80% health. But probably by that point, I'll have gotten a new MacBook—because it's going to be at least another year or so till that happens, at least that's my prediction.
 
I’ve replaced a (swelling) battery on a 2015 MacBook Pro. Short of that (swelling & 8 years old) it’s very uncommon to need to replace a battery at all.

I had apple replace my iphone 13 mini once under warranty. Once it dropped to about 90-92% the rate at which the battery died greatly accelerated. I'm just wondering if that was a fluke or how things happen here. I honestly haven't seen anything that makes me want to upgrade. Performance gains are minimal and I don't do anything outside of web surfing and playing Civ V or something when on flights with mine. I'd basically gotten it as a media consumption machine because I travel for work and wanted something that had great battery, good screen, great speakers. Maybe a m3 macbook pro will change that but this is the first time in a long time I've held onto a machine for more than a year. I normally just buy another and sell the current one. But when 10% battery is 2hrs of runtime lost that starts to add up.

Egads !!

There's nothing wrong with a battery that's at 94% of original capacity.
It's a process called "aging". Happens to all things.

When the capacity drops below 80%, then you can avail yourself of Apple's battery replacement program, which costs $249. You get a new Apple-labeled battery, installation, and a short warranty.

"Apple labeled" can make a big difference. Seems like 3rd-party batteries are a crapshoot. As Forrest Gump said, like a box of chocolates: "you never know what you're going to get" ...
