How has everyone’s battery health held up after a year of use with an iPhone 11 Pro. Mine is currently at 89%, and I was wondering where that falls in line with everyone else.

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.

11 Pro Max, owned since launch day. Charged over night every night and often sat in a charging cradle or plugged in various times a day. Now at 96% health

100% after a year. 40%-80% charge rule since Day 1.
That’s hardcore preventative maintenance.

I’ve never gone to those extremes, but I try not to let mine go below 30% too often, which I think helps slow degradation a lot.

My iPhone 7 is now at 81% after 4 years on its original battery. Battery was starting to drain quicker just lately which is one of the reasons I just upgraded to a 12, but the old girl has done well.

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+.

what is the 40 - 80% charge rule?

I believe it’s keeping your battery operating between that range. It will give you more cycles on your battery. I think it’s 30-80.

The kicker is if you do that then you are living as if the battery has lost 50% to keep it from reducing health by 10% in three years or so if you don’t wireless charge and use 5w overnight. I still think one should avoid deep cycling and having it in the charger for long periods of time at 100%.

iPhone X at 94% after 3 years. First year did wireless charge but the health took a hit so I stopped. I use 5w at night with a plug timer to charge to around 90% at night.

I was debating the same thing but I am going to trade it in for the 12 Pro because I have the 11 Pro on the Apple Upgrade Program

If I didn’t trade it in at what level would they replace the battery at on the 11 Pro? I am debating keeping it for someone else too because of the small amount of payments left in comparison to them buying a new phone

Under warranty? 80%< after 1 year I think. You can pay the $30 or whatever it is to get it replaced before then I think. My 11 Pro has had some quirks since day one, with the lightning port acting a bit odd and the wireless performance randomly being bad. It’s the main reason I’m not keeping it and also a small reason why I decided to upgrade.

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.

I’ve had my XS Max for nearly 10 months. I try not to let it go under 30% most of the time and occasionally I’ll let it go down to 25%. I always charge overnight, and I occasionally fast charge. It’s still at 100%??

I wasn’t expecting that, normally I’d be in the mid to low 90s on our 7s.

11PM launch day at 94% now. Haven’t noticed battery life being down because of being a pro max.

90% 11 months for my 11... Wondering how the wireless charging had an effect on this...

98% on my 11 Pro. I've charged overnight every other day with 5W/12W charger and optimized battery charging on. 18W charger is still in the box.

94% on an 11 Pro, mostly just overnight charging (with the included 18w charger) but occasionally during the day too. Still very happy with the battery life.

100% after about 9 months on an 11 Pro. I don't deep discharge unless I have to and I'll generally do a topping charge on a wireless standup dock I have during the middle of the day if I am using the phone a ton. By and far the most consistent battery on any electronic device I have ever purchased.
