Re: 80% battery charge

Everyone says that the phone's battery should not be charged more than
80%, to maximize battery life.

battery wears out.
 I don't like charging only to 80%.  Then when I've used it a while, it's
only 60% or 40%.  I don't like discharging below 30 or 40%.  Isn't that
bad for it too?
 Even if not, the closer I get to 10% the more I worry I won't have
enough battery for the whole day.  Starting at 100 instead of 80 greatly
lowers the risk of discharging below 20.
 So isn't that reason enough that I can just charge to 100 every night
and not worry about my battery wearing out?
 Also, it's a pain to have to pay attention to how much it has charged.
If I forget to disconnect it, it goes to 100.  So shouldn't I just stop
thinking about it?

I use a 25 Watt-Charger for my iPhone and it takes less than 45 minutes to charge from 30% to 80% SOC. Then a loud voice I programmed informs me of the fact and asks me to disconnect from the charger. Same at 90% with a clear instruction to unplug.
Newer phones give the possibility to automate the charging process. They learn when you go to bed and you get up usually and they charge to 80% at the beginning and charge to 100% short before you get up.
iPhones are able to manage the charging process for many years and my Pixel 7 has a similar capability.
BTW: From time to time mobile device batteries should be charged to 100% to recalibrate the electronics. Do not discharge the battery to a point where the device shuts itself down. Especially do not store a phone with a LiIon-battery completely discharged for a longer period of time.
