I feel like the battery capacity reporting could be a bug in iOS 16.

I've been using Coconut Battery for close to a decade, and it's been very accurate for me with every device I've used.

Coconut Battery shows me my battery is closer to 94-95%, while iOS 16 shows me 92%.

Launch day 14PM. I'm at 90% according to the phone but I haven't run coconut in a while. Up until a few weeks ago, I charged only through the apple magsafe puck. Now i'm using a modrn dock. Seems really high deg compared to previous models.
 
My 14 pro is at 90%. Magsafe most of the time, but plug in car for Car Play. Does seem like I'm charging during the day more often. I am on 17 beta tho....
Was a launch day phone.

TBH, it could be a lot of factors and some combination of...

- Battery degradation from heat from charging (+ with a case on)
- Battery degradation from environmental heat (leaving out in the sun, etc.)
- Battery component quality - I heard Apple sourced batteries for the 14 line from two separate sources 🤷🏻‍♂️
- Software-related bugs that result in battery drain, causing us to charge more and more = putting more cycles
- iOS 16 bug that shows the wrong battery health %-age

We will never know until Apple publicly addresses this or calls for a recall. I think the latter will be the case here!
 
Battery manufacturer: Desay Corp.
Battery manufacture date: 22/10/17

Most of times Im not full charging or using always on display and i use Shortcuts automations..
And charging only by slow charger

Mine just went from 100% to 99% a few days ago.

Weird.


Always wireless charge mostly.
 
theory:
- iPhone chips get hotter every year
- iPhone 12/13 were primarily used indoors due to covid, away from sun
- now with travel booming again, iPhone 14s are being used outdoors
- heat from sun + hotter chips = seemingly degrading iPhone 14 battery faster than previous models

Interesting.

My job is an essential position, so I was still at work outdoors. My 12PM battery still deteriorated on iOS 14.1.
 
yikes!! mine is also at 91% and I don’t do anything weird either.

My phone frequently overheats and has to pause charging in my car. I have a feeling that contributed to it.
I had never seen the charging on hold message until I got a 14 Pro. And I was just setting up the phone for the first day in an office with AC... That phone got really hot when using it in the sun while hiking...

Despite the 14 Pro Max supposedly having better thermal offloading of the processor, the phone itself seems to get significantly hotter than I ever remember the 13 Pro Max getting.
 
Launch day 14 Pro at 95%.

Charges on a Nomad Stand One MagSafe charger if I need it during the day and plugs into an Apple 20W charger at night with optimized battery charging on.

Thought I'd revisit this. I'm now at 91% less than two months later. This is pretty atrocious.

Foremost, the health percentage reported by iOS (in Settings) is a calculation, could simply be an average of logged full capacity readings and/or even the highest. Either way, Apple’s official battery health gauge is going to have higher accuracy than coconutBattery’s at this moment reporting.

Next, and possibly most important to understand, neither is absolutely accurate (especially with common charge habits).

Well mines been “stuck” on 87%, launch 14 Pro, for about 7 weeks now strangely.

I’ve just checked coconut and it states 425 cycles, seems a lot higher than some on here.

Also just checked a trade in site and they’ve said 80% battery and less than 500 charge cycles, first I’ve heard that, so I’m close!

I wasn’t particularly going to upgrade this year, but unsure because of battery this year, it’s been poor (not that next year be better!?!?)

I have AC+ presume if it goes less than 80% even in month 20 say, they swap it?
 
Everyone comes up with the same reasons for battery degradation. But how about cheapening of the manufacturing to save some bucks and was reported on last year. What about the manufacturer. We were doing that in another thread. I’m Desay and still at 100% one week after launch day and manufactured in August.

That's my understanding - re your question at the end there. The moment it drops to 79% you can ask for a battery replacement with AppleCare+.
