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

But they also say that most people will get a new phone before their
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?

It just is not practical unless the phone automates it.

Just put the phone on a slow charger when you go to sleep, and forget.

Great answer. Just what I wanted to hear, and from one of the most
reasonable posters I know.

I charge it from the USB port on the computer. I don't think anything
is slower than that. ;-)

Depends on the computer and port. Traditionally, the USB port would
supply "1 load", but some computers can supply way more.

I have a charger with 8 ports. Two are "load 1", four are "load 2", and
the other two are "fast", at the time I bought the thing. The "load 1"
ports are ideal for charging the phone, except that my current phone is
"smart", and when I plug it at night it doesn't charge at all, and waits
till sometime before the wakeup alarm, calculating to be fully charged
when the alarm rings. BUT, the slow charger is then not capable of
giving the load the phone wants :-D

So I had to move the phone to another socket. In any case, I plug in and
forget.

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.

Yup, don't worry about it. It'll only really make a difference if you
are a very heavy user or keep your phones for 5+ years.

Typical usage - i.e. nightly charging - works fine for easily 3-4 years.

I charge to 100% overnight, every night. Been doing it with every phone
I've ever owned. So far I've changed phones before I had any noticeable
problems.

My current phone, a Galaxy S10+, turns 5 years old in a few weeks. So
far no noticeable problems...

However I did make one modification with my current phone. I bought a
wireless phone charger that came with a 10 watt power supply. I then
replaced it with a 3.5 watt power supply. My theory was that the slower
charging would create less phone heat and since I was in no hurry
(overnight) the longer charging time wasn't a problem.

But then I've always been a light phone user so as always YMMV...
