Sorry, but you are absolutely wrong this time. My iPhone 15 Pro Max is 99%. I got it day one. 289 cycle count.

I’ve been doing this since the 12 Pro Max. Each year, 100% health.

I decided to try it and I can say conclusively that charging to 80 works.

@davidhmccoy When do you enjoy this 99% health?

@gruber @davidhmccoy I am in a similar boat, 100% health/Day 1/233 cycles/15PM. I use maybe 60% of battery a day. So even if I charged to 100%, I wouldn’t “enjoy” it. My wife now gets the phone and she upgraded from a 13 mini. 80% for her is like triple the battery life.

@gruber @davidhmccoy the things that don’t seem to be talked about is how heavy of usage the phone is under. Light use all day might be easier on the battery than heavy usage for a couple hours. 🤷🏻‍♂️

True. I also run a bright screen. I turn off the auto-brightness. I want that thing blazing so I can enjoy my many lock screens(check my posts).

I treat 80% as my 100%, that is, I keep it topped off at 80%. Originally with the 12 Pro Max, I would check it constantly and unplug it. I saw that worked, but man! It as labor intensive.

I have automations that turn off my iPhone charges at 80% and that alert me to when it hits 80 or hits 65%. The charger turn on at 74% /1
