iPhone 12 Pro Max Bluetooth Issues

i had the same problem.

I went to general->reset->reset network connections

Power your headphones off

Then under bluetooth when you switch bluetooth on, aubsiquently press and hold your headphone power on button until they appear and you hear “pairing complete”

How about restoring the iPhone and not loading your backup? (at least for testing purposes) By some of the comments here, it seems that some of the problem is a corruption/artifact in the Bluetooth profile on the iPhone, which erasing and starting from scratch should resolve (if its not a hardware fault). BTW, two 12 Pros in the house here, and no such Bluetooth problems since acquiring them.

I had posted the same problem on this thread a couple months ago. Just recently GJ69hud posted the solution - unpair your blue tooth device. So I followed the instructions to unpair my Sennheiser momentum headphones, then paired to my new iPhone 12 Pro Max and I am back in business. I wonder if I can pair my headphones to two different iPhone generations - something to figure out another day. I also read resetting your device i.e. headphones back to the factory settings.

We have 4 12 Pro Max and about 20 bluetooth devices to unpair and pair from the 4 XR to erase and trade-in. They all didn't work after we transferred data with the new system of laying the max and xr side by side. Unfortunately , this wonderful easy way to transfer also won't automatically tell the bluetooth devices to transfer it's love for the max. The users have to tell the bluetooth devices to forget the XR and accept the Max. Erasing the XR contents including from the iCloud did the trick for some of our devices but not all. Some like Bose, I had to use its app Bose Connect to pair with the Max. The iCloud updating is great but also created this problem.

Success! I have the early model Bose Soundlink and through Bose tech support was able to connect my IPhone 12 pro max today.

There are two methods for resetting the Soundlink

1) Hold down the mute button till you hear a sound - this resets the entire unit (this was unsuccessful)

2) Hold down the Bluetooth button till you hear a sound - this clears connected devices and was successful after a few tries. I had to power down the Soundlink a few times. At first it recognized the Soundlink on my IPhone (which it wasn't doing before) but no sound was transmitted. After the powering down of the Soundlink it began to play. At no time did I have to power down the IPhone. If you play with it you should be able to connect.

Ok folks here’s what finally worked for me! Be sure your old phone is wiped! Whatever device you are trying to connect to your phone hold the power button for 15-20 seconds making sure your phone is searching for Bluetooth connection eventually it will show the device now pair with it. Did this to several devices now all are listed and no issues.

As for connection to my truck I had to go in and add new phone several times before they found one another code matched than I could hit pair and again now this phone automatically connects.

First iPhone I had to do this with other than that hiccup all else is awesome! Thanks Roy for leading me away from the phone and working more on the device to connect to!

Here is what i had to do. Reset my headset. Then in my car i had to add the new phone. Bam Bluetooth worked for everything. It was not the iphone nor the phone service. It was the devices i was trying to add. Reset Your devices not your phone.

A person on this thread said to turn your headset (mine is a Sena snowtalk2) off to reset it. The factory resent on Sena is to click on the right earphone button for 15 seconds. I did that and it worked! Immediately upon turning the Sena back on, the Sena paired with my iPhone 12 max pro phone.

Sending a big “thank you” to the person who said to try this (see Dec 4th post)!

I just changed my phone name from HugoTheConqueror's iPhone 12 Pro Max to HugoTheConqueror's 12iPM. Paired the phone to the BlueTooth device again and problem solved. For some stupid reason (which i have no idea what it is), once i got rid of "iPhone" in my phone's name, the problem just went away. Maybe other BlueTooth device just don't appriciate the power of "the iPhone".

had the same problem, i did two things not sure which fixed it, but its fixed.

1. switched off my old phone
2. renamed my new phone the same name as my old phone

immediately my new phone recognised bluetooth devices.

do you have your 12 pro’s since launch?

I think it’s a hardware issue with the first batch. My second iPhone 12 pro have none of this bluetooth issues, but my launch iPhone 12 pro will have

Yes, a day 1 order for a 12 Pro and then later a day 1 order of a 12 Pro Max, both delivered a week from order.

Some of the comments in here imply that removing the Bluetooth profile of the device from the old iPhone helped, which to me seems to suggest some sort of artifact left in the backup loaded onto the new iPhone. Restoring as new should confirm that, not that that's a pleasant solution.

Following another's advice, I delete bluetooth profiles for my former iPhone XR connections. pairings on my Sennheiser wireless headphone, and then my iPhone 12 was able to find the device. reading some of the posts on this thread brings to memory the song by Conor Oberst - You All Loved Him Once. ;o)

Well ! I turned off and then on my elit ja bra 65 active too during the process when I reset the settings of my iPhone .. so it could be that it only needed to turn off and on the headset ..

I ultimately got a replacement 12pmax and it works fine now. Defective hardware? Maybe they changed something in the Bluetooth hardware ?

I ended up having to reset the BT on all my appliances (for Bose speakers it was pressing the BT button for 15 seconds) and re-connecting. It is now working ok.
