iOS Update 15.8.2 Critical Bugs

Actually, after looking around there does appear to be a number of others who are affected as well.

There are 2 billion iPhone users. No matter what problem you have, there are guaranteed to be others with the same problem. So the fact that others are affected, especially for a failing battery symptom, is not really useful information in troubleshooting.

You have done all of the reasonable troubleshooting that you can. Contact Apple support, or make a genius bar appointment, and Apple can run diagnostics and identify the problem. But it is most likely a failing battery. Is this the original battery? If so, I am certain that is the problem. If the battery has been replaced, how long ago? And by Apple or a 3rd party (meaning not with an Apple spec’d battery).

Hello~ What’s your battery health? To check click on below and review. If your battery health is 80% or below have the battery replaced.

Check the iPhone battery health and usage - Apple Support

Genius Bar Reservation and Apple Support Options - Apple

Also try a forced restart…

I had no issues on iOS 15.8.2.

Go to Settings/Battery/Battery Health and read the message about battery condition.

I had very similar issue as you described. When updated from 15.7.x to 15.8.x my both iPhones (SE 1.gen & 7) started to behave strange - shutting down with charged battery (fyi, on SE bat. health was 100% without any issues before update) etc... This was not only issue - battery was draining much faster than before, especially when using wi-fi and during the calls.

Frustrated by this behavior I've decided to revert back to 15.7.x (I still have older blobs stored) but the downgrade didn't helped at all, it was the same. So it is not iOS what is causing this issue, it might be either latest baseband or SEP firmware...

That symptom is usually a battery with a high internal resistance, but usually the battery health message catches that, at least on newer phones. It may not have in your 8 year old design.

6S Plus ios update affecting phone operation

Defiantly appears to be a software issue as the phone acts like it has malicious software installed. Consistently locks up, opens additional pages on search engines without touching screen, unable to answer incoming calls at times, etc. Almost unusable now.

I updated to 15.8.2 three days ago. Since then, on two occasions my 6s has unexpectedly turned off needing charge to turn on. Shows red charge icon when I plug in, meaning very low charge. Soon after that I check, it turns on and there’s way more charge, equating with the charge level before the shut down.

Battery health is 100%. This did not happen before the very recent update.

It is well known that Apple has done updates in the past which, by design and with reported intent, has sped up the decline of battery life and slowed down functionality of older devices.

It's "well-known" but wrong. Apple throttles phones that already have old, failing batteries so that the phone does shutdown suddenly and unexpectedly, leaving someone without a phone. What they got in trouble for was not disclosing this as clearly as it was felt they should have. And, news flash, iPhones still work this way.

I see Apple’s stock declining over the next few years as more people tire of Apple’s tactics and jump ship to Google products.

You should always buy the tool that best meets your needs. However, I suggest you take your investment advice from a professional.

I updated to 15.8.2 recently and my microphone stopped working. I can’t make calls or record audio. Even videos record without sound. There’s a noticeable delay in everything now. Camera delays a lot and stutters when recording and even delays when pressing the capture button for photos.

Just updated to 15.8.2 today. Battery health is fine and normal but everything is delayed, from clicking on a app to starting up the phone. There is a noticeable delay now and it’s extremely disappointing.

Updated my iPhone 7 to iOS 15.8.2 recently and since then my battery loses charge rapidly - losing about 50% overnight while on flight mode. It's an old phone, but battery lasted just fine prior to the update. Would appreciate Apple fixing this issue and sending out a new update!
