So, this has been an ongoing issue with my iPhone 15 Pro Max for a while now. Initially, I didn’t encounter many Bluetooth problems when I first bought the phone. However, after updating it to iOS 18, the Bluetooth issues became more frequent.
I use an Apple Watch, AirPods Pro, and also CarPlay. My Apple Watch would constantly give out notifications about “iPhone not found” every 10 minutes. Additionally, my AirPods Pro wouldn’t connect. I had to put one AirPod in, play music, and then put the other AirPod in for it to work. Sometimes, the Watch or AirPods would appear connected in the Bluetooth settings but wouldn’t function properly. (For example, the AirPods wouldn’t play music through them, and the phone would play music through the speaker even though the AirPods were connected. The Watch also wouldn’t send pings to the phone, and so on.) Even the iPhone Mirroring feature on my Mac wouldn’t work.
I’ve spoken to Apple Support multiple times (recently in 2025), and they’ve suggested the following solutions:
1. The first time I spoke to them, they advised me to remove VPNs, disconnect all Bluetooth devices, and reset the connection settings. Then, I should reconnect all devices one by one. For instance, I connected the Apple Watch and waited for 1-2 days to see if the connection dropped. Then, I connected CarPlay and then the AirPods Pro. Everything worked fine until the AirPods Pro were connected on the last day. Before that, everything worked fine (except for minor issues with CarPlay), but then after connecting the AirPods Pro, the problems started again.
2. The second time I spoke to them, they suggested resetting the entire phone and then reconnecting the devices one by one again. However, this didn’t resolve the issue.
3. The third time I spoke to them, they advised me to try resetting the phone without loading the iCloud backup, which would give me a fresh start. Unfortunately, the same issue persisted after connecting the AirPods Pro.
4. The fourth time I spoke to them, they suggested that I go to the Apple Store for service.
So, either the 15 Pro Max has a connectivity issue where multiple devices randomly disrupt the connection, rendering it useless, or the AirPods Pro are interfering with the other connections. That’s my experience with this issue.
TL;DR: iPhone 15 Pro Max experiences frequent Bluetooth connectivity issues after iOS 18 update, affecting Apple Watch, AirPods Pro, and CarPlay. Apple Support suggests various troubleshooting steps, including device resets and reconnections, but the problem persists.
