iPhone Battery capacity down to 99% on iPhone 11?

31 cycle is high considering you have your phone for just over a month.

Yeah I'm now starting to be a little concerned as its now up to 34 cycles. It's not been fully drained or anything since I last tested a couple of days ago on Coconut.

My typical charging cycle is overnight from 2200-0600 which optimised charging is working for, and on Mondays and Thursdays I use the phone most of the day as a sat nav so its on the wireless charger in my van most of the day, and for the little short journeys I do in the car its connected via a wire to CarPlay.

I wonder if wireless charging whilst using could be causing the excess cycles as from what I recall when wireless charging the iPhone uses battery and the charger tops it up constantly, whereas when wired the iPhone draws its power from the wire bypassing the battery entirely. Although my XR was used in the same way and was still reporting 100% capacity after 9 months usage, but it did seem to have excess capacity over 100% to begin which my 11 does not however.

I have also lost around 12-18mAH in capacity in the last couple of days according to coconut, however this could be due to environmental factors and I could plug it in again tomorrow and the mAH comes back. Battery life is a finicky beast I have noticed, some days you have more than others.
 
and now its back up to 3115mAH so over 100% capacity, I'll keep an eye on the cycles as that stat is worrying but the capacity is up and down like a yoyo by a few mAH so I'm not too worried there. That few mAH fluctuation would be why iOS drops its health percentage quickly when in all reality the battery is still likely still at a higher capacity.
 
My 11 Pro Max is still at 100% after 16 charge cycle. Got mine on launch Day.

My Iphone X, around 625 days old and 640cycles.. coconut shows 88% and the same shows in battery settings .

I think its really good stats for so many cycles!
 
Mine dropped to 97% after four weeks, Apple swapped it out no problem for me after I had some severe overheating issues.
 
I think I might have a dodgy battery in my 11. Its just dropped to 98% after 45 Cycles and that is with this supposed "Optimised Charging" which I have checked is working correctly.

By comparison my wife's XR still has 99.6% after 160 Cycles, at this rate when I get to 160 mine will be lucky to be 95%

Is this bad enough for Apple to switch the battery yet?
 
Well just spoke to Apple over the phone and they are claiming the capacity drop is normal, but they’ve still booked me into a Genius Bar appointment to see if the store will exchange it, although they’ve said the won’t guarantee they will though.

Hopefully I get a nice Genius who will swap it out for me, I mean 2% drop after 45 charge cycles vs a 1% drop over 160 cycles that my wife’s XR has is a significant drop.

Just my opinion, but I think you’re obsessing a little too much over the battery health.

Its a brand new phone which isn't performing as well as a 9 month old phone, I don't want to have the battery go into throttling mode the week after the warranty runs out forcing me to shell out for a repair.

Given the fact that Apple's adverts are pushing the battery life of this thing as a selling point, this is the worst performing iPhone I've had in terms of battery health.

If the battery continues to deteriorate at this rate by the time my 18 month contract ends I'd be lucky to make it to the end of the day without a charge in between.

I get that there is the potential for it to now hold at 98% for ages and deteriorate no further, but on the flip side it could fail prematurely too and all signs are pointing to premature failure, especially when you compare it to my X that I traded in after a year which was still on 98% and my XR which I sold to my friend after 9 months which was still on 100%. My charging habits haven't changed hell even the equipment I use to charge is the same.

You can see why I am concerned about this when you look deeper into it.
 
Well I've cancelled the Genius appointment as I am now busy with work, what I will do is monitor it for a bit longer and if I loose more capacity by the end of the year I will try and get a replacement. I may be lucky now and the battery will stay at 98% health for the foreseeable future or it may continue to plummet I guess time will tell.
 
So did a DFU restore as was having some software gremlins and wanted a clean start, battery has dropped to 96% health now.

The battery definitely seems screwed, maybe I should've kept the Genius appointment.

Wonder if its screwed enough for Apple to replace it yet, as Online Support did their remote diagnostics and said it was ok still but that was Wednesday when it was still at 98% health
