It's been nine days since Apple released iOS 16 to the public, bringing major changes to the Lock Screen, Messages, Maps, and more. In the days following the release, some users have encountered several issues on their iPhones, ranging from slow system performance to battery drain.

In the past few days, iPhone 14 Pro users have shared specific bugs related to Apple's latest high-end iPhones, including camera shaking, iMessage and FaceTime activation issues, and more. There are other issues, though, impacting the broader group of iOS 16 users, and we've aggregated two issues based on user reports below.

Abnormal Battery Drain

ios-16-1-beta-2-battery.jpg

After a major iOS update, it's normal for your iPhone to deplete battery life faster as it conducts indexing and background tasks; however, some users across Twitter, the MacRumors Forums (1, 2), and Reddit (1,2) are reporting excessive battery drain days after the update.
Wow, iOS 16 is buggy. Completely wrecked my battery life on my 13 Pro. Now I have a 14 Pro and all seemed well, was getting great battery life, and now have had horrible battery life today. Like estimated 4.5-5 hours of SOT. And now, out of nowhere, my phone started getting really hot. What is going on??? Apple please fix this mess.






Other users are reporting an improvement in battery life compared to iOS 15, so the overall experience is rather mixed. Apple has recently acknowledged that enabling haptic feedback for the keyboard in iOS 16 may deplete battery life, so users experiencing battery drain could try turning that off if they have it enabled. If you're still experiencing battery issues, see our explainer.

Slow Spotlight Search

A more prominent issue facing iOS 16 users is slow performance in Spotlight search. Users are reporting that Spotlight sometimes takes up to 10 seconds to load results on iOS 16 and sometimes doesn't load at all. Users on multiple Reddit (1,2) and MacRumors forum threads (1,2) are sharing their experiences:
I have the same issue. Before iOS 15.6 search was instant, but when I updated to iOS 15.6 it became very slow, taking more than 5 seconds for anything to show up while searching. I was hoping that iOS 16 would fix the issue, but it is just as slow. I even erased the phone and restored it from an iCloud backup, hoping it will fix it. It didn't.
So Apple, please fix this problem in the next update. It's super annoying and I don't want to lose all the network settings because of this.

I use search on the phone to quickly pull up apps I have hidden or are several screens away. When I pull down and type to search, it takes sometimes 10+ seconds for apps to begin to appear in the search. They used to be almost instantaneous. Example, if I start typing M-A-P, Apple Maps, Google Maps, etc. come up as a result. Is anyone else noticing this massive slowdown?
For this specific bug, multiple users have said that resetting all settings significantly improved the performance of Spotlight search, but an official solution and/or bug fix has not been issued by Apple.

New iOS 16 Update Coming Next Week

Apple has confirmed that it's aware of some of the issues being experienced by users, including camera shaking on the latest iPhone 14 Pro, and has promised an iOS 16 update next week. The update, most likely to be iOS 16.0.2, will include a fix for camera issues, an annoying copy and paste prompt, and iMessage and FaceTime activation. The update could also address other issues being felt by users, such as including battery drain and slow Spotlight search.

Maybe because I have a iPhone 14PM that I don’t notice the battery drain. It seems normal to me.

I’ve not noticed battery drain at all. My watch? Sure, the first day or two.

The indexing/slow spotlight I did notice the first few days after installing the GM, but it’s been fine since. While the indexing does take time, I think it is a lower priority process so takes some idle time to finish.

For me it is the stupid "Find My" draining battery (over night) and thus presumably also throughout the day. Funny enough, on my iPad I do not even have Find My activated (it does not leave the house) and all location services turned off but it still shows the Find My in my battery stats 🧐
Same problem here. Rather annoying.

iPhone 12 Pro here, and yes, battery drain is worse. I notice that Apple News was taking a lot of my battery, so I turned off background update on that, and it seems to have mostly solved the issue. So I guess, check your battery drain and see where it's going.

I can confirm slow spotlight and when I close it swiping Home Screen pages is not responsive for a couple of seconds.

Guess we found the 3 people that are having “widespread” issues. Lol

Very glitchy and slow, and battery drain definitely seems much more than usually.

Camera app gets stuck in horizontal or landscape and won't return until I close the app.

Spotlight search was already messed up by one of the iOS 15 updates. But now it's even worse.

Without adding to the hysteria, I struggle to see exactly what has prevented Apple from fixing the biggest of these issues before iOS 16 launch?

Whatever the case, I'm definitely not jumping on iOS 17 before 17.1 or 17.2 drop. No way any improvements to iOS could be worth the.

Here. Actual data:

iOS 16 is using 10%-15% more of the battery vs. iOS 15 on iPhone 11pro.

See attachments.

It’s kinda wild to be reading a MacRumors article and see your own post featured in it lol. Thank you MacRumors team for making these battery and performance issues more known so that Apple can hopefully become aware (if they’re not already) and fix them!
I stressed for a second that is was my own post regarding Spotlight 😅

But yes it is a problem since at least iOS 16 Beta 4. Strangely, this problem also affects my M1 iMac with macOS Monterey 12.5 and 12.6, with Spotlight and Mail. Mail Search can sometimes take up to an entire minute! Does it happen to anyone else?

This is what happens when a manager is not flexible about a release date of something, let it be an OS, a video game, a construction, etc. Common mistake in any company.

This 100%. Project management types refuse to budge on anything and just rush stuff out the door to make themselves look good instead of being flexible when issues arise or problems are discovered. They know everyone will blame the dev teams so it's no sweat off their backs.
