How do I fix persistent Bluetooth dropouts on iPhone 16 running iOS 26.3?

Hello! I have an iPhone 16, and have been having trouble with Bluetooth over the past few months, since October 2025. From time to time, and with no obvious reason as to the cause, Bluetooth will drop out and refuse to connect to any device. It won't connect to my Apple Watch, it won't connect to my car, nothing. The odd part though is that the Bluetooth toggle in the settings reads as On all along. I have toggled it off and back on again, which does not make a difference. Seemingly the only way to fix the problem is to fully shut down my iPhone and reboot it.

I'm running on iOS 26.3 (23D127).

Does anyone have any recommendations for what I could do to fix things?

Thank you!

If multiple devices are dropping out, the issue likely lies with the iPhone's communication stack. You'd better resetting the network settings.

Go to Settings > General > Transfer or Reset iPhone.
Tap Reset.
Select Reset Network Settings.
Your iPhone will restart. This clears out the cache for Bluetooth, Wi-Fi, and Cellular.

Maybe set your forum default sort order to "Oldest" in your user preferences to follow the thread as it was posted.

The iphone in question failed on hardware.

Wanted to follow up with you, I was trying to put the phone in diagnostic mode, and the phone stopped turning on altogether. I took it in to my local Apple Store, where they told me the motherboard had failed, which also explained the Bluetooth issue. Thanks for your advice!

Without removing teams for a while and trying again it couldn't be assigned to it specifically.

Before the reboot option, next time, try force closing all apps in the background, i.e. swipe an app halfway up and swipe up all other apps.

I must say in the last 3 years my Watch has never disconnected from my iphone.

Others may come in with more suggestions once USA has woken up.

Any thoughts on what software may interfere? I mainly just use Pocket Casts, Spotify, and Apple Music over bluetooth, but I do have Microsoft Teams on the phone as well for occasional work stuff. I have seen a bit about Teams causing some Bluetooth issues but haven't been able to figure out if that's related. I do not have any VPN on the iPhone.

Thanks for your response!

Intermittent connectivity problems are difficult to diagnose but unless you have VPN or other interfering software, it suggests failing, not yet failed, hardware.

I'll try the force close option, thanks!

And I'm fairly sure the issue isn't with the watch, it's with the phone, because it won't connect to other things, such as my car with CarPlay either.
