Apple needs to fix it on XR as well. My phone say 95% in iOS but 98% in iMazing. I’m sure they are calculating it differently, but the iOS measure seems oddly static. It also doesn’t show that many new devices these days are actually around 103% when new.

My 11 Pro is down to 88% after a year and a half, which is shocking to me because I've never gotten below 95% on any previous phone after two years. I haven't changed my use or charging habits at all. Maybe this explains it.

Same here! My iPhone 11 pro, bought day 1, is at 88%. It was 92% before a couple of last updates, and dropped 4% in one shot!

My iphone x has 3 years and is at 86% using it the same way as the current 11 pro. I have warranty until september so if this continues dropping I hope I am at 80% before warranty is over, to ask for a free battery replacement!

I checked the cycles and the iphone x duplicates the 11 pro more or less, so i think my battery is deffective or so. Both iphones charged wirelessly at night with mophie 7,5w charger, sold by Apple.

So this is only for iPhone 11 and not 11 Pro models?

You didn't even read the first line of the article. Did you?

Same. I just installed the beta and while it hasn’t recalibrated it shows 88% on my iPhone 11 Pro. 😑

Wonder how many of us are on 88% battery health? Seems common.

 

[Rochy Bay]

Apple's iOS 14.5 beta that's currently in testing introduces a new process for recalibrating the battery health reporting on the iPhone 11, 11 Pro, and 11 Pro Max.

As outlined in a support document, Apple says that the update will recalibrate the maximum battery capacity and peak performance capacity on the iPhone 11 models to address inaccurate estimates of battery health reporting that some users have encountered.

Symptoms of this bug include unexpected battery drain behavior or in some cases, reduced peak performance capability. Apple says that the inaccurate battery health reporting does not reflect an issue with actual battery health.

Once the update is installed, iPhone 11 users will see a message in Settings > Battery > Battery Health about the recalibration process, which Apple says might take a few weeks.When the recalibration is complete, the maximum capacity percentage and peak performance capability information will be updated. If the recalibration indicates that battery health has indeed significantly declined, users will see a battery service message.

In some cases, recalibration may not be successful and a battery service message will pop up. Apple says that it will replace these affected batteries free of charge to restore full performance and capacity.

“battery health bug” LMAO. Good one Apple....

Same for me! My iphone 11 is just barely 14 months old and it’s at 88% too. I never used to charge my phone more than once a day until a week or so ago when my battery just started draining with light usage and now i am having to charge twice a day. I hope this update really fixes whatever bug is causing this

 

[NorthernSkyLights]

Interesting to see this. I’ve had my iPhone 11 Pro Max since June last year. And the few updates my battery health went from 100% for so long then ios14 came along then battery health went to 98% then few months down to 94%. Now my battery health at 92%. I guess I’m playing to many games.

 

[Ikertxo40]

Same. I just installed the beta and while it hasn’t recalibrated it shows 88% on my iPhone 11 Pro. 😑

same here, recalibrating.

sometimes i open imessage or camera app and the iphone 11 pro takes a while to show msgs or so, something that never happened when new. i wonder if they know the batteries are not ok and this is making it softer to digest for us.

I read in the read more option that we might get a message to change battery for free after recalibrating…

 

[RalfTheDog]

My 12 Pro Max now shows 200%. I guess that is why it slowly charges itself up every time I use it.

LOL! Mine is sitting at 94%.

 

[zipster]

Interesting. My 11's battery health dropped to 88% around 3 months after I bought it.

A year later it's still at 88%.

 

[xmacvicar]

This is very interesting. I just had a genius appointment 2 days ago regarding my 11’s huge drop in max capacity. It went from 100 to 94 percent, seemingly overnight. At the genius appointment, we watched it drop to 93%. They ran diagnostics and said it was fine.

I just got this phone at the end of December; its still very new.

My 11 Pro is at 90%, which isn’t terrible because I’ve used it a ton and it’s been a year and a half. But my iPhone 12 Mini is at 94% in less than 5 months.

 

[JonaM]

Just checked my 11 Pro and 88% as well. Now could be coincidence, but 88% does seem to occur a lot!

 

[BaltimoreMediaBlog]

The latest IOS 14.5 beta wrecks notifications to the ground, so Apple better get their priorities in line.

Because under Timmy, it's always 1 step forward, 2 steps back to fix what we broke!

 

[PhillyGuy72]

Sheeh, how about a recalibration of 12's (and Pro, Pro Max)??

My Health is draining much, much faster than my XS Max did - 2 years, 2 month of that and it was 94%, (12 PM now at 96%, loss of 2% in 4 weeks - just 4 months of use...and I'm a light user. 37 cycles now, that's it.)

*I brought this up in another thread, many report 100% or 99%...few at 95%, 96% on the 12's
Like I said in the other post, something seems off with this battery in my phone.

 

[CJ Dorschel]

Just checked my 11 Pro and 88% as well. Now could be coincidence, but 88% does seem to occur a lot!

i’m wondering if that’s the baseline for newly installed devices and that percentage changes over the weeks of recalibration. Almost everyone I know with an iPhone 11 Pro who installed this recent beta - including myself - shows 88%. 🤔

I don't have the beta. I've been on 88% for about a month, and am currently on the latest standard public release.

 

[Derek87]

i'll be interested to see how this helps people.

as a different vantage point, i'm still at 99% according to the Battery Setting page on my iPhone 11 pro. Coconut Battery on the Mac, however shows i am still about 101% design capacity. this is after 1 year of ownership and 150 cycles.

my wife's more heavily used iPhone 11 (bought Sept 2019) is at 91% and i haven't had the chance to connect it up to a Mac and try it against Coconut battery.

i'm wondering if the glitch is that the number shown doesn't dynamically adjust like it does with Coconut battery...ie, if for some reason, it reads low at one point, it will never go back up even if the capacity is estimated as greater at another point in time.

 

[Dave_]

When the iPhone 11 was new my employer changed everyone's work phone to an iPhone 11. I'm slightly surprised by some here saying they charge theirs once or twice a day: I charge mine once a week whether it needs it or not!

 

[Acronyc]

This is interesting and it makes me wonder if my battery is affected. I got my 11 I’m November 2019. So just about 2.5 years. My battery is at 91% capacity, but it dropped from 98% to this in about two months. I haven’t changed my use patterns and was surprised to see it drop so much in such a short time.

 

[Charlesrfinal]

My launch day 12 pro max is still 100!

This is strange as I bought my 11 Pro on 1st October 2019 and battery health is 96%, whereas my 12 Pro is less than 4 months old and battery health is 98% and my work SE (v2) also 4 months old is 96%. In my book the 11 Pro battery health seems to be OK. It will be interesting to see how a recalibration affects it.
