Sitting at 92% as of posting this on my 11 Pro Max and I’m still getting anywhere between 9-11hours SOT, phone still lasts well over a full day, it’s only limitation is me and the fact that I plug in overnight just so that I can wake up to a 100% charged battery in the morning.
The battery health number is simply an estimate, it can sit at the same place for months and then jump down by multiple % at any given time when it self corrects. Yours may self correct at some point as no matter what we do batteries degrade.I do the same thing most of the time. Why is mine still 100% ? I am confused. Sorry.

My suggestion to you is that when it does self correct do not panic, as long as your battery life is good you are fine, don’t put too much stock on that number. Although I am at 92% my battery life is still phenomenal.
Did the same thing. Almost always low power mode and dark mode.100% after a year. 40%-80% charge rule since Day 1.
2 years now, and battery health is still at 93%!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.
I bought a secondhand iphone xs with a genuine apple battery replacement. I use shortcuts to remind me to start charging the phone. Whenever I start charging process it also switches to low battery mode with an automation. I charge it up until 81% from the time I got it. I start charging with a 5V apple charger around 40 - 50% and the battery health keeps dropping at least 1% on a monthly base. It has a cycle count of 250 cycles. I really don't get what I'm doing wrong... This should work right? I've been pretty consistent with the charging times with the occasional spike to 90% but that's it. I bought the phone on 94 percent in october (10-04-21) on 94%. and it's 89% today (12-28-21). It's becoming very frustrating! I really don't know what I'm doing wrong.
Anyone some advice? Thanks!
Maybe it’s a defective battery? See if apple will replace it again. Idk much about apple and replacements but they might?
I’ve had apple support run a remote diagnostic and said that the battery is performing normal. Wow..another percentage down in less than 2 days after my last recharge to 80%. Health is 88% now. I’m letting the 40-80% thing go. It’s not working for me. Degradation has never been this quick with other phones. Very disappointing…thought that I was doing a good thing but I guess not…
Wow. Now you have to tell us more. What is your charging technique? Are you a heavy user, or a light user who charges every couple of days? What's your average screen time on a daily basis? Do you charge to 100%, and/or overnight? Thanks.11 Pro Max from launch...battery still at 100%. Charging methods include a wireless pad, MBP charging brick, MBP itself. Fantastic battery life - I get at least two-three days on a single charge with normal usage.
my iPhone XS, the batter was down to 90% in far less than a year, and after 3 years it was 79% so took it in to get replaced. although I took it to an apple authorised repair centre (but part of a big electronics retailer) they said they didnt have apple batteries in stock but had 3rd party which were just as good except it wouldnt tell me my battery health any more.
3rd party battery is only 3 month old and to be honest it lasts about as long as my old degraded official apple one, wish I hadn't bothered to change it. Coconut battery says it holds 96.6% of its design capacity of 2658 mAh but honestly its low battery after a day at work same as my old 79% one.
I think battery health has less to do with an arbitrary battery charge level (80%, 85%, 96%, 100%, etc.), and more to do with how long the phone is connected to a charger. At least, that my running theory from reading all the anecdotes of various users.My XS dropped another percent to 88% since my last post.(yesterday) f**k it. I’m gonna maximize usage and replace the phone whenever I feel it doesn’t perform to my standards anymore. I’ve been doing the 40-80% thing for about 3 months now and the health dropped exponentially!
I’ll be replacing the battery probably around mid 2022 since if this amount of degradation keeps up. I heard that the XS had poor battery life but this is ridiculous.
The previous owner had the battery replaced on march 2021. I’m so disappointed.
Thanks for the response. What wouldI think battery health has less to do with an arbitrary battery charge level (80%, 85%, 96%, 100%, etc.), and more to do with how long the phone is connected to a charger. At least, that my running theory from reading all the anecdotes of various users.
One has to also remember that charging from 20% to 80% probably takes almost the same amount of time as charging from 80% to 100%. Also, if your iPhone is connected to a charger, it will trickle charge the phone even if it already reached 100%, or even the 80% charge set through battery charge optimization by Apple, thereby increasing the time the battery is spent charging!
I am thinking of purchasing a smart plug and having it schedule charging at night from 1:00am to 2:30am everyday to limit the charge time. I am not going to babysit and set notifications, etc
