100% after a year. 40%-80% charge rule since Day 1.
That’s hardcore preventative maintenance.100% after a year. 40%-80% charge rule since Day 1.
what is the 40 - 80% charge rule?
89% here as well. Wireless charge every night (Samsung Duo charger I got for free with my Note 9), with a bit of car charging and fast charging a couple times. This year I will probably avoid wireless charging overnight, I'll stick with the 5W adapter. I might get a wireless charging pad for my car though.
I also have had to charge throughout the day for the past few weeks and most days I would end with <20%, often less than 10%. Definitely pretty heavy usage. If I were keeping it I would get the battery replaced with AppleCare+.
I used to do this and I am SO glad to have gotten over it. It definitely works, but I realized what’s the point? Even the most hardcore users can get 18 months from a battery. A new battery is about $80 or so. That means that in order to use your phone from 0-100 and charge at any time, it’ll cost you about $4.50 per month. My wife is on her phone all day long and her launch pro is at 92%. Not great for sure, but it’s still manageable. Next fall I will either get her the 13 pro or a new battery. My 1 year old 8+ is still showing 100%, and I don’t baby it either.100% after a year. 40%-80% charge rule since Day 1.
My XS Max was at 92 when the 11 came out.
Taking it in for replacement today at 86% for the next 2 years of life.
