I don’t understand all the charging to 80%, then only discharging to 20%. You are losing 40% of your battery just by doing that. It makes no sense.
If your battery loses 20% of its capacity in 2 years by charging whenever to 100% you are still better off than not using 40% of the battery capacity from day 1.
I do not mean to disrespect those who have a strict charging code, but I just don’t understand the logic.

I agree, if you spent more than a few hours time thinking about this and letting it effect your schedule, which over the life of the phone you will, you could have just worked a little OT or something instead and got the money to replace the battery.

However to play devils advocate the keeping the battery near its nominal voltage (3.7 volt I believe) there is less stress on the battery. That 40% is probably closer to 75% of the battery wear and tear on the batteries health overall. And if your schedule supports charging in that manor and it doesnt negatively effect you then why not? Besides how other people waste their time is of no concern to me.

My launch day iPhone 11 PM which I abuse the hell out of, charging in hot places, letting it goto 0% because I dont want to get off the couch, then letting it sit on the charger all weekend because I don't want to see the notifications I'm missing, etc is at 85% battery health. And still easily last me all day even on days I consider "heavy" use. And at this point I'm thinking I'll probably get the iPhone 14 and none of that thought process has anything to do with battery, at least outside of this forum...
 
I just charge it when it needs it and don't worry about it.
For more important things in life than eeking a couple of extra months out of a battery.
It's Liion and it's not going to last more than 4 years even if you don't use it at all.
I'll pay the $69 happily every time I need a new one which is usually 3 years.

Its not just about ”couple of extra months” of battery life. Itˋs most importantly about safety and enviroment for most of us. It is about reducing unnecessary battery waste that we create in this planet, which is by the way a really huge deal.

We know by now that charging your phone is pretty safe, but we haven´t still collected the data for more than 10-15 years or so. Scientifically, it is not long enough period to say what is absolutely safe or not. There is also many new variable in the equation like older devices, counter fake parts and so on. These things are actually far more complex than we think.
 
66% for 6 hours? I don’t remember getting that kind of SOT with XR even on launch day for 100%, what iOS version are you running, what’s your battery health & what kind of apps are you running? I’m impressed.

Here’s mine, iOS 15.4.1, mostly use Safari, 84% battery health, my SOT used to be like 4.5-5.5 hours in its prime on an earlier iOS version

I mostly use efficient apps like Apollo (for Reddit) and Tapatalk (various forums), and then Safari and News are my top native apps. BH is 93%. Here’s an SOT comparison after nearly
3years (and a marathon day).

Never charge 80% or above?

Sometimes - when I need it like off-grid backpacking, and perhaps to run a 100-0 battery test/battery meter recalibration every year or two. I look at it like redline on a car motor, it’s there if I need it, but most of the time, I just use the lower RPMs for efficiency, environmental, and mechanical sympathy reasons.

I’ll eventually need to raise the peak charge setting to offset natural battery time decay, but suspect it’ll take >5yrs before requiring >80% to meet my 8-ish average daily SoT usage.

Agreed, people get worked up about this when batteries are easily replaced by Apple at a very modest fee and with full resealing of the waster shield.

I know as soon as you bring up battery you will get battery experts saying the complete opposite of each other but curious how many people put their phone on the charger every night regardless if they have 1% left or 80%

I always place my phone on the wired charger around 10.30pm. I don’t leave mine charged overnight. I leave it plugged from 10.30 to midnight. Usually my 13 PM is around 60-70% before I plug it in.

My 13 Pro max which tbh is hardly used ends up c 56% each day despite having 100% battery condition

When I first got it battery life was awesome , now not so impressive - probably a bug in the os
 
Only charge on Carplay in car which is slower, and on Wireless charging iHome which i believe is 7.5 max. 97% health and got 13PM on launch day.
 
Launch day 13 mini, have never plugged a cable into in, left on a Belkin 3-in-1 wireless charger almost every night and also use a MagSafe puck in the car. Only recently has it dropped to 99% health.

It's a tool I use it however light or heavy when needed, while charging it when I need. Not going to go out of my way with a charging schedule in an attempt to preserve battery health. When it drops to a point I notice the battery not lasting as long as I need, I'll get it replaced.
 
I keep my iPhone 11 charged between 20 and 80%. Not sure if it's true, but I saw that as a recommendation somewhere.

Only time it gets to 100% is if I fall asleep while it's on charge.
