You’re fine but if you let your battery die every time it will slowly degrade and then you will definitely need a new battery over time. I had every Iphone model from the original SE until today and all of them had 100% battery health within 1,5 years of use. The secret? I never let my phone drop less than 50% and i definitely never let it die. Don’t let your phones battery go to 0%. One time is fine. Too many times and you will see your battery health go down fast. And for last , my wife’s Iphone 13 pro max that’s about six months old has a battery health of 93% because she’s too lazy to charge it and always lets it die until she puts it on charge. So 🤷…
