Worn out batteries don't just have limited capacity, they charge slower and create more heat while charging due to internal resistance. I'd much rather charge to 80% for my typical day, but have the option to 100% charge on those rare occasions when I know I might need it (long day travelling, etc).
Personally, I have a Shortcut to put my phone into "low power mode" once it hits 90% (why not?).
Maybe a Shortcut could do the same and turn off power once it hits 80% on your overnight charging dock and then use a small amount of power while the screen is off.
Isn't low power mode for when your phone has very little battery left? I don't understand why one would put a phone in low power mode when it's charging and hits 90%.
Personally, my 15 pro can do >72 hours on a single charge WITHOUT doing stuff like this, even starting at 80% (note: mostly standby, no always on display, with ~3h screen on time total). The 80% limit is definitely something I'll be using virtually all the time.
For me, I find the performance/lost functionality fine: https://support.apple.com/en-ca/HT205234
Replacing an iPhone battery at an Apple Store costs about 1/3 the price of the phone by the time you need it replaced, so ideally one would want the battery to last as long as the lifetime of the phone.
Case in point I’ve a 6 year old dell laptop that is set to shallow charge to 75% in BIOS and the battery still holds 3 hours of charge (from 75% to forced standby)to this day.
Counterpoint. I have a lenovo thinkpad t480s that I bought second hand and is now 4+ years old. The battery lasts at least 6 hours. I haven't discharged it fully in a while to be more precise. Ubu 22.04 running in power save mode as selected from the default gnome menu.
Dell? Yeah, terrible company making terrible laptops for sure. Used to think differently before owning one.
An iPhone battery replacement is $49-99 at an Apple Store.
> 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...)
Personally i hate the optimized battery charging ios does. It’s awful. I’d rather being able to keep my phone plugged in basically 24/7 and always have it ready to go, but not have to worry about expediting its death.
Technology should be as transparent as possible in my opinion and not bring us back to thinking about said technology, just what we can do with it.
It's tiresome enough to worry about having a charged phone, i couldnt bring myself to look at battery percentage or even phone charger options just because i am calculating how long will my phone last in the long run.
