As promised here are the observations I have made over the last week or so, as sent to Gary at Waterfield just now.
My summary of the observations below is:
1. I had initially postulated that the problem might be conflicts between connected devices if the APMs were put into the case (butterfly up) when I had not manually verified that only the iPhone (and no other device) was connected to the APMs. But that doesn’t appear to be the case—and it shouldn’t be because AFIK the magnets should force the APMs to disconnect from all devices anyway.
2. Duration of storage with the butterfly up does not seem to correlate with having problems connecting. See incident on 4/27 where the problem occurred after only brief storage in the case with butterfly up.
3. Happens whether charge on APM is at 100% or not.
4. No problems encountered when the APMs are stored in the case with the butterfly down.
--------------------
4/25
In case overnight with butterfly down. No problem
Didn’t use (100% charge) but put back in case (failed to note position of butterfly-shame on me!—while walking using Beats headphones to listen to Audible. When tried to use APMs they allegedly connected but I got no sound. Actively disconnected Beats from iPhone but still no sound—even though allegedly still connected. Disconnected APM, reconnected-No sound. Plugged into power caused APM to disconnect. Reconnect attempt- connection unsuccessful. Plugged in then attempted to reconnect. Finally successful
Ran APM connected to Gym iPad for 2 hrs then switched to iPhone without problem. 92% charged. Placed in case with butterfly up and plugged in. Idea was to leave APMs this way all night and then be sure nothing else is connected to iPhone before pairing in AM
4/26
Left APMs overnight in case w butterfly up and APM plugged into power. Checked to see that no other headset was connected to iPhone, then unplugged APMs and connected without issue to iPhone.
1PM Put in case w butterfly up but not charging
4:50 PM Connected immediately w iPhone
6:50 PM Put back in case w butterfly up (power at 79%) and plugged APMs in.
4/27
Unplugged and APM immediately connected to iPhone.
Transiently placed back on butterfly at 8:15 while connected to iPad in gym
9AM took off butterfly and CLAIMED it connected fine. However, when I tried to switch APMs to iPad, I got no sound despite the iPad saying the APMs were connected. Had to plug the APMs back in to power briefly in order to get proper connection.
10:10 switched to iPhone. After verifying that APM not connected to iPad, put APM onto butterfly (at 93% power)
11AM Appeared to connect to iPhone in that battery widget gave proper battery reading. However there was no sound. (YES, I checked that proper output was selected for audio). Tried reconnecting to power—no joy. Finally had to reboot APM
The point here was that the butterfly was up and the APMs were not at 100% and were not plugged into power. Also duration of contact with magnets was very short—not overnight as others had reported. Also there was no issue of conflict between iPad and iPhone for connection with APMs as I had postulated on 4/25.
Used APM for an hour or so (listening to Gov Scott’s presser) then put them down in case with butterfly down while I ran errands, was out and about.
9 PM Put APM on and they connected just fine. Battery at 81%
At this point I decided to test whether there were problems if I simply did not use the butterfly. If there was, then that would suggest a problem with the APMs and not the magnets in the case. These are the results of that testing:
9 PM Put APM in case with butterfly down and plugged into power, starting at 81%
4/28 - 5/2
Basically there were no problems connecting when the APMs were stored long- or short-term in the case with the butterfly down. Details follow
4/28
Connected immediately w iPhone the next morning after being stored overnight with butterfly down and APM plugged in. Charge went from 81% to 100%
Put APMs in case with butterfly down several times during the day without problem connecting once taken out of case
9:30 PM Plugged in overnight with butterfly down, starting with charge of 74%
4/29
Connected immediately. Charge at 100% after overnight storage w butterfly down and plugged in
10:50 Back in case with butterfly down
12:10 PM switched to Beats, APMs in case w butterfly down
4/30
730 AM Connected immediately. Charge 88%
Switched back and forth between iPhone and iPad (Gym) without incident
2:50 PM Put APMs in case with butterfly down, plugged in for the night
5/1
Paired fine with iPhone and Gym iPad. Switched back and forth and even to MacBook Pro, then back to iPhone - all without problems
8:45 PM Put into case with butterfly down and plugged in, starting at 79%
5/2
Connected fine, used for 1-2 hours with iPhone. When went to use with iPad had to actively disconnect iPhone from APM before iPad could connect with APMs (usually switches when APM selected in Settings on iPad and system automatically switches from iPhone to iPad without requiring manual disconnect of APMs from iPhone).
Listened on iPad for 1-2 hrs
Switched to iPhone, verified iPad not connected to APM then put APM in case with butterfly UP and APMs plugged in, starting at 91% charge/
At this point, having seen for 3-4 days that there are no problems when the magnets are not engaged by the APMs, I am going back to testing the case with the butterfly up.
