Some iOS 16 Users Continue to Face Unaddressed Bugs and Battery Drain Two Weeks After Launch

14 Pro. Only issue I have is some occasional screen jitter when scrolling and camera not focusing in certain app.
Battery life is good and no other issues.
My wife”s 14 Pro has issues with autofocus in the camera app. 16.02 update didn’t resolve. Might be a hardware issue. We’ll see after the 16.1 update is officially released.

I unplugged my 14 Pro with 100% battery and went on a two hour walk while listening to a podcast and no other apps running. In two hours, it went from 100% to 62% battery. It's abysmal.

The podcast app has always been a battery hog. Kills my wife’s phone all the time. Did it with her 11 Pro, 12 Pro, and now her 14 Pro. Her phone gets extremely hot too.

2020 SE 2. Running 16.0.2. Battery life has never been good. Its now much worse. I go to bed at 100%, wake up at 80% or so. Phone on standby during the day uses battery much more than IOS 15. Running stock apps (no facebook, instagram, etc...).

Turn off all things under Siri (Before Searching, Content from Apple, Suggestions from Apple). Also check your Analytics and Privacy Reports (they tend to "reset" and turn them back on after a major update I noticed), turn off all Background App Refreshes (just leave it "On" on the top, but uncheck everything, it will still come in just fine); Remove notifications for Apple things that you don't use (like Screen Time, App Store, I turn them off); Under Location Services, check that all of them are "While Using" or "Never", and not "All the time", and try not to use Precise Location; Under System Services, turn off "Product Improvement". Under "Privacy and Security", turn off "Research Sensor & Sensor Data" if you don't use. Under "App Store", don't use Automatic Downloads. Turn off "Exposure Notifications" under Settings. Turn off "Tracking" under "Privacy and Security" too.

These are some of the things I did and battery life holds out pretty good.

My iPhone 14 Pro Max (16.0.2) drained the entire battery while I slept last night. Caused my wake-up alarm not to go off, made me late to work. This screen shot shows that it was the Exposure Notification app going wild! No other app ran all night, but that one chewed the battery down to zero.

I always put the phone screen side down, by the way.

No, it really isn't. This is what happens when you have extremely complex systems and users expect no bugs from a .0 release.

what's so extremely complex about these very incremental updates and UI changes just for the sake of change?

i'm downloading 15.7 as we speak and won't update back to 16 ever. 1 year old phone that had 90% of battery at the end of the day because I barely used it now has 60%

No problems on my 14 Pro, but on my girlfriends 12 battery is drained by late afternoon. Yesterday it was the weather app (!) which supposedly ate about 30% battery. Something seems wrong but it doesn’t seem to be a general problem.

I’m glad if that helps you, but we shouldn’t have to disable a ton of on-by-default settings to get back to the battery life we had on the last OS version. Workarounds are fine, but apple needs to fix this for real.

I see roughly 10% battery drain per hour on my M1 iPad Pro when not in use and the display is off. It drains faster when being used, too—in other words significantly faster than it used to drain when being used.

They never have and they never will. They just keep adding and not fixing the old ones. I'm just showing what can be turned off to increase battery (quite a bit in some cases too like having everything under Background Refresh on).

I've run into a couple bugs with Messages and Music. Sometimes in Messages, the app simply stops responding. I have to terminate and restart it.

Yesterday, Music stopped outputting audio any time it moved to the next track in my playlist. I could see that the song was playing by the progress indicator, but no sound was coming out.

Interesting. I had to restart my phone to get my music to play yesterday 👎

Well, the first thing to adjust is your view of "very incremental updates and UI changes". I bet you might be surprised to do a deep dive into what was changed.

Don't update to iOS .0 releases would be my suggestion to you, wait for the .1 and you likely will be much happier.

They’re listening to your mic and using your camera in the background even if you’ve denied permissions. Nobody believes me, but they do this and I’m sure of it.

I’ve talked to coworkers about things, for instance one day in the breakroom we were discussing sparkling water, a specific brand. I wasn’t in Facebook while I was using my phone. I never Googled the water brand, I have never purchased the water brand.

Later that day, that evening, I was getting ads in my FB feed of the exact brand we had discussed - and it isn’t popular or a major known brand. There is absolutely no other way unless they were listening through the mic.
Click to expand...
Did any of your co-workers search for the water brand? Or interact with the brand in any other way? (like clicking an ad they saw, visit the website with a FB tracker on it, etc)

FB's systems are quite good at making connections between things. If you've all used the FB app once (or it ran in the background) at the same place, it'll connect the dots even if you're not friends on FB itself. The system might say, "Bawstun's co-worker looked at this water brand, maybe he'll be interested too?" and show you the ad.

Years ago, I had the app installed on an Android phone. I'd take it to work, etc. FB would often suggest "people I may know" who were customers I'd seen recently! Complete strangers!

Having said all that, it would not surprise me at all if FB did manage to exploit around the permissions system somehow, but on the whole IOS does keep apps out of things they shouldn't.

No issues for me. Previous iPhone 12 would be totally tapped out at the end of the day (using it 4-6 hours). iPhone 14 Pro under the same usage gets down to maybe 35-40%.

I had to turn off "Always on" (Ironically) for my battery to not drain tremendously. With minimal use battery would drop 20% by my second cup of coffee

With that kind of huge drop it sounds like some process is stuck. you might want to reboot your phone to see if it is better after. Even though a #.0 version like this often has less efficiency it should not be that bad.

My 14 pro drains more or less 15% overnight while on standby. This is with the always on display off.
i check the battery app and all it says is Find My app.
Click to expand...
Put it in Airplane Mode or power it off overnight,That's what I've always done.
 
Please add the TruTone bug to that list.
TrueTone doesn't work after unlocking the phone and then abruptly adjusts itself to the correct color temperature about 5-10 seconds after unlocking.

I overall think that iOS 16 is OK with some nice additions but I've noticed shorter battery life and GPS issues on my iPhone 12 (as well as on Apple Watch OS 9.0 - Apple Watch OS and Apple Watch battery life have always been very mediocre anyway)

Before iOS16 update, I can usually charge my iPhone 13 Pro Max once every 2 days. Now at the end of the day I'm always left with around 20% battery which won't be enough for the next day. 99% battery health and no change to my usage habit. The drain is real.

This is with every new iOS release and previous gen phones. Just a way to make people upgrade faster. Just weird how battery drains faster every iOS release.
