Some iPhone 11 Users Seeing Increased Battery Health Percentages After iOS 14.5 Recalibration Process

[MacRumors]

In the sixth beta of iOS 14.5, Apple introduced a recalibration process for the battery health reporting system on the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate battery health estimates for some users.

Apple said this process might take a few weeks to be completed, and now that two weeks have passed since the sixth beta of iOS 14.5 was released, some users are beginning to see revised battery health percentages. 9to5Mac writer Benjamin Mayo tweeted that his iPhone 11 Pro's maximum battery capacity relative to when it was new increased from 86% to 90%, for example, and tech website The 8-Bit has compiled other users' results.

In a support document, Apple said this bug with inaccurate battery health reporting does not reflect an issue with an iPhone's actual battery health, and the recalibration process should resolve the issue. Symptoms of the bug include unexpected battery drain or, in a small number of instances, reduced peak performance capability, according to Apple.

While the battery health reporting system is recalibrating, users will see an "Important Battery Message" in Settings > Battery > Battery Health, but the displayed maximum capacity percentage will not change during recalibration. When the process is complete, the new percentage will appear and the message will be removed.

In a small number of instances, recalibration might not be successful and a new battery service message will appear. If this occurs, an Apple Authorized Service Provider can replace the battery free of charge to restore full performance and capacity, according to Apple, but the company ensures there is no safety risk posed to customers.

iOS 14.5 has been in beta testing for over two months and could be released next week. Apple will be hosting a virtual event on Tuesday, April 10 at 10 a.m. Pacific Time, with a new iPad Pro and other announcements expected.

I can vouch for this. My 11PM went from 88% to 93%. Good stuff!

 

[Maclver]

How long until someone sues.....?

 

[otternonsense]

Shouldn't we wait until it's actually released to the public first?

 

[pcd213]

While my calibration is not yet complete, I immediately went from 100% to 98% the moment when 14.5 was installed.

 

[FocusAndEarnIt]

I went from 87% to 88%. Big whoop. I definitely notice a difference from when I got it originally, which at this point was almost 18 months so it makes sense. Miss that first month battery life though.

 

[NorthernSkyLights]

The recalibration done nothing for my iPhone 11 Pro Max same reading it had before battery still at 91% overall health. Oh well.

 

[Ikertxo40]

My recalibration went from 88% to 100%, day 1 iphone 11 pro, so this feature is clearly not working, at least in my case. I was hoping recalibration would not work, and ask for a battery change, as even 88% was too much drop compared to my iphone X from the past, same usage, still at 86% used by my partner, 2x age of this iphone 11 pro at this point...


It is impossible my battery is at 100% health. Coconut battery shows today 90%, way more credible.

Why does this sound like the last battery fiasco. Apple hiding something again.

Same feeling here, and my iphone 11 pro lately is very warm, on top of erroneous recalibration above posted

This is just an educated guess based on looking at how long it charges, drains and then charge again.

It doesn't actually mean anything. Just because it was 80% and now 90% after this, it does not mean you got 10% more battery. It just means they haven't figured out how to accurately display the health of a chemical reaction based fuel.

In other words, a battery with the 90% "guess" can and will die as fast as a battery with 50% guess.

All of this is for support only, they have incentives to keep it high as much as possible to avoid people replacing under warranty until warranty expires and they can charge you more for out of warranty replacements.

Bingo. Trying to not have to replace battery under warranty. Seems like Apple has used some inferior battery’s again. Now it’s time to hide the fact again.

 

[travis64]

They’re obviously doing this so they don’t have to replace the batteries below 80%

 

[DougieS]

Mine went from 84% to 87% after calibration but then to 100% as apple broke a screw repairing my screen and replaced my phone!

 

[div12]

its April 20 not April 10 should be updated on the page.

 

[szw-mapple fan]

If that’s the case, then there would be no reason to replace the battery anyways, since it means that the holds the same amount of charge.

 

[Gudi]

Uh, my XR is at 83%. I could need a recalibration!

 

[Stunning_Sense4712]

I am concerned that Apple might be yet again covering up another design flaw or product defect since they have a history of doing this and getting sued years later.

 

[Nordichund]

I would say that I'm an average user. i have had my pro since November 2019 and the battery capacity has remained at 100%. Though I have noticed it doesn't seem to last as long as it first did. Whether that is a battery fail or due to IOS upgrades I really don't know. I would have been a bit worried if it said 105%

I intend to keep this phone until at least the 2022 upgrade ? It is a great phone.

 

[JCCL]

No changes for mine. Stayed at 88%

 

[Td1970]

I’m definitely gonna get my battery replaced with Apple care. Gonna get another 2 years out of my 11PM.
My phone is still recalibrating. Been doing it for 2 weeks.

 

[Td1970]

Ok. So it finished while I was typing. Went from 92 to 93. Still being throttled according to the peak performance section.

kinda sad that a battery at 93% capacity can fully power the phone

Maybe, maybe not. There’s a bunch of “stuff” that happens between the battery and the device receiving its power, and it could be that “stuff” is being influenced by this miscalculation and not actually sending the full duration of charge to the device.

My guess is probably a little less educated than yours but I wouldn’t be surprised if there were some truth to it.

 

[gbf]

Does anyone else find it weird that the word optimized is spelt wrong in the OP?

 

[Eso]

Yikes, this is just a scam to avoid having to replace devices for battery service (which they refuse to do until the battery drops below 80% capacity). Just like when the iPhone 4 came out and suddenly Apple discovered a "bug" in how the bars were being displayed (after 3 years). Then they patched the software to show more bars, and made the bars taller in the UI to boot!
