Battery indicator percentage error iOS14

I did factory reset as well - didn't help at all. Yesterday I turned off the Optimised Battery Charging and left the phone for the whole night plugged into the charger. Today battery indicator seems to be much stable... Also weird thing, optimised battery charging is being turned on automatically - I'm turning it off permanently and after some time it's on again. Anyone experiencing anything similar?

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.

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.

I have had this—definitely the battery meter is inaccurate or failing to update. I had a 1-hour call and the battery % only dropped 10% and that is simply not possible given the typical drain from a phone call.

It was reading 84% which simply wasn't possible, so I rebooted the phone to try to force it to update. It didn't change at all. I let it sit for a few minutes, then had another call. The service kept cutting out and I noticed it suddenly dropped from 84% to 44%, then another sharp drop to 25%. Then it stayed the same for the rest of the call, even though in reality it must have been getting close to 15% or even 10%.

I was on the phone with support a couple weeks ago explaining that I was seeing instantaneous drops of 50% or more and that clearly the battery indicator wasn't working. They stated it had to be a hardware issue, not software, but there was no explanation of why this issue didn't appear until iOS 14.

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...

I am on an original iPhone SE, but it was purchased brand new and activated around April 2018. So it is only about 2.75 years old.

I use minimal data/app traffic and have kept it charged religiously, so the battery health was still at 100% when iOS 14 dropped. Then, I started having a huge drain of 10% per hour or more. I did a factory reset which did nothing, then removed all Amazon apps which eliminated most of the massive drain, but it is still upredicable and draining faster than before.

One month after iOS 14, the battery health had gone from 100% to 95%. Since then, I have kept it in low power mode at all times using a script, and keep it plugged in almost all the time. That seems to have slowed the degradation of the health %. But the battery indicator simply isn't accurate and clearly there are problems.

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.

I have the same issue, now on iOs 14.3. Battery down at a low % and when you reboot the phone it shows the real level. Just done that and jumped from 27% to 97% and it was fully charged an hours ago. Definitely a bug, only started happening to me following a iOS upgrade. At first I thought it was the usual background work the phone does following an upgrade chewing up the battery but it isn't. Also seems a but random. I first noticed it weeks ago, then it went away and has been fine for weeks but has just started happening again.

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.

Aren't these the guys who got caught slowing down iOS on older phones so you users would upgrade? I think a $1000+ device should last more than 2 years. Heck, they even glue the phone together so you can't change the battery! This may be my first and last Apple product.

If I ever questioned whether this issue was real, no more:

Woke today with 1% battery showing and even had a pop-up recommending "low battery" mode.

Immediately powered off.

Upon power-on, battery shows as 63%.

Hello everyone, I need help with something.

I’ve got an iPhone 6s updated to the latest iOS version (14.3). Although the battery’s maximum capacity is 69%, it keeps giving me false readings.

Onetime the battery level was at 8% so I switched it off. When the power came on, I plugged it, it turned on and read 40% charging. Hope it’s not a serious problem.

I have the same problem with a 6S which is 30 months old, it can still charge to 100%. when around 80% it can rapidly drop to nothing within minutes and go blank, when resetting with on and home buttons it can shoot back up to 80%. I have had support from apple who says the battery requires replacing which I have put in motion. I will post on this forum with the results.
