1/3 the price of the phone? An iPhone battery replacement is $49-99 at an Apple Store.

The rest of that was, > about 1/3 the price of the phone by the time you need it replaced So that sounds plausible if iPhones can be purchased for $150-300 at the age you'd replace the battery. (Though that does strike me as a little low, still? Depending on how long the battery lasts...)

How is that logical? Why would you buy a phone for $150-300 that’s the same as the one you have, likely with ann old battery for that price, instead of replacing the battery for <$100.

For a while I had my phone charger plugged into a smart power outlet and a shortcut to turn that smart power outlet off when the phone's battery hit 80%. It would then turn the power outlet back on at 2pm the next day for it to be ready.

I also use the shortcuts app, but since I dont have a smart outlet it just send me a notification (on my apple watch) when battery charge is above 80%. I also have another shortcut to notify when battery is bellow 20%.

Many people charge overnight while sleeping, so that would be really inconvenient.

The Chevy Volt has the perfect handling of this: A new car never charges past 90% or drains below 10% battery. It simply reports 100% when the actual battery isn't quite full and vice versa, extending the battery life significantly. As the battery life degrades over time, it will try to keep the same useful range, and shrink those boundaries until you are using the full battery life each charge. Perhaps this works le…

I've never understood why these companies don't just add a redline: make the battery chargeable to 110%. By default have it stop charging at the recommended 100%, but let the user decide if they need that to go beyond that and are willing to damage their battery health to do so.

> let the user decide

Most users don't know enough about battery chemistry.

WAY too many people don't even understand how USB charging work, their brains are still stuck in the barrel jack charging ages where the charger pushed power and the device just took it (or blew up).
