Battery indicator percentage error iOS14

I did the same thing yesterday after reading your note and today the optimized battery charging switch is turned on. When I initially turned it off, there were two options (besides cancel) “turn off until tomorrow“ and “turn off“. I chose “turn off“ but that didn’t hold after 24 hours.

It does appear to be a software issue since, as you say, this began only after I installed iOS 14. My battery health has stayed at 91% since the first time it was shown. I'd love to try a new battery, but doubt it would make a difference. My sister has iPhone XS Max on iOS 14.3 with no issues. I'm using a 7. Perhaps age does play a factor...

Yes, that why I posted it only in response to an iPhone 11 user.

But this may be a first; Apple acknowledging a known problem before the fix is released. I’ve never seen that happen before. And I suspect, based on private information I have, that the the release will not be next week. I hope I’m wrong.

I did not have the 1% issue but it would go from high 80s to switching off, on switching back on would be very high still. In hindsight it was though the software couldn’t’ the evaluate or manage the failing battery output.

Agreed. I have an iPhone Se 1st edition and it will do the following...

Battery goes below 52% (the lowest I've noticed) and I turn the phone off for the night.

Turn the phone on the next day and it says low battery of 1% at the main screen or shows the icon of the cord below an empty battery image and does nothing.

Turn phone off for a few seconds, reboot once or twice, and it will show around 20-30%.

Plug into computer and in very little time it's back up to the percentage it was before all this happened.

This has happened several times and it seems a temporary fix (at least for me) is to not let the battery drop below 55%. If I remember to do this then the issue never comes up.

Did you read any of the posts? The issue is not whether the phone has charge and can be used, the issue is an apparently faulty/randomly-inaccurate battery % indicator.

That battery is over a year older than when it should have been replaced. Do it now or it could destroy the device around it.

Update: I have now spent two separate days with the battery percentage indicator turned off (just so I don’t obsess over it) and battery life, when I do check, is as abysmal as previously seen. In the past 5 minutes of looking at this forum on Safari, my battery indicator went from 98% to 89%. Earlier in the day, the phone went from fully charged to 30% battery in less than three hours with almost no use. Battery health shows 91% and says my battery is currently supporting peak performance.

There’s really no good reason I should be contemplating a new iPhone, but I don’t think there’s any other option. It doesn’t appear this will get any sort of a fix.

believe it or not, I was able to buy a new original iphone 6s 128GB last year in a real store... had Apple's warranty for it which just expired...

instead of having this ridiculous conversation about when 6s was released, can someone please explain why it happens to other users as well? it happened for me just after upgrading iOS to 14.2, my iphone works fine for entire day without charging. Only the battery indicator is not showing correct information!

I agree with you that Low Power Mode shouldn’t be the cause of these issues, but I don’t claim to be a software expert. Your comments makes sense to me regarding sudden bursts of activity, but I would think Apple is already prepared for such actions.

I have, twice now, done a complete reinstall only to find the battery-indicator issue begins to reoccur within 24 hours.

Perhaps our phones and batteries are old. I don’t believe, however, that I should need to replace an iPhone that is only 3 years old just to properly run a new iOS. I guess I might have been happier if they had simply made iPhone 8 the cut-off for running iOS 14.

Still trying to figure this out. Before going to bed, I closed all open applications. For the first time in weeks, my overnight drain was only 10%. However, once I started using the phone, battery percentage dropped rapidly to 60% and then to 45%— all within 10 minutes. Interestingly, it has remained at 44% for the past 30 minutes while visiting various websites.

Great. Earlier this week I bought a new IPhone 11 for my wife because the battery indicator kept dropping rapidly on her 6s. Today my 8s started the same trick. Zero use and 50% battery reading. Now I find it’s a SW error. Am I happy????? I am trying the optimise charging fix switch off referred to above but don’t have much confidence in it.

I am not sure which it is now, display error or drain. Yesterday my 8 dropped fro 35%. A reboot instantly raised it to 46%. Then whilst I watched it and I was doing almost nothing it went from 46% to dead flat in 1 hour, and it really was flat and turned itself off. Crazy to watch the display counting down whilst you watch it!

I have always had app refresh turned off, and yesterday I went through and turned off loads of locations services I did not realise were on, but they were all, bar one, set to "whilst using the app". The exception was Bitdefender set to always on for some reason, so I turned it off. But still the power dropped like stone.

Today the phone has behaved normally, and is currently at 65% at the end of the day. Bizarre behaviour.

The somewhat randomness of the readings is driving me as crazy as the general inaccuracy itself. For the past week, I close all apps on my iPhone before I go to bed. Some mornings (after being unplugged all night) my phone is at 92% or 84% and others it is at 51% or 49%. The only thing that ever shows as having used the phone during that time is Siri; I’m not sure why Siri is even involved overnight.

How many people with this “bug” bought a new iPhone because they thought their phone was old and dying? Sales ploy by Apple? I have been using my phone all day long at 1%. This issue should be easy to fix. But why would they? Hmmm.
