I think you’d do much better getting HA’s that allow handsfree calling (possible with Phonak and more recent MFi HA’s and more recent iPhones, 11 and later). The output of the watch speaker is relatively weak and since it’s not a MFi device, the caller’s voice is not going to be routed to your HA’s while you have the ability to speak into the watch mic, AFAIK.
The Apple Watch did rescue me recently when I went outside and locked myself out without my keys. The wife was sitting at the kitchen table with the blinds drawn since it was nighttime. I’d left my iPhone in the house in the kitchen, too. Rather than knock on the kitchen window and try to yell through double-paned insulated glass, I called my wife via the Watch. She said the call quality was excellent via BT through the kitchen window to my iPhone on the table, but I could barely hear her voice through the watch speaker even holding it up to my HA’s (I didn’t try adjusting the speaker volume by twisting the crown).
If Apple offers emergency satellite calling through the watch someday, that will be a game-changer.
Relative to my previous comments on my Apple Watch 6 battery durability, I should have noted that I run my watch on very power-conserving settings. The screen is set to turn on only by touch or crown-click. The apps on the watch are not allowed to run in background. I normally only use a BT connection to my iPhone and don’t usually run Wi-Fi from the watch. And to avoid notifications on the watch, I set it in Do Not Disturb mode (but something about upgrading to the iOS 16 BETA has disturbed this - I’m now getting notifications like crazy on the watch).
I don’t need notifications on the watch as any notification on my iPhone creates some sort of ding in my HA’s. If my watch is within range of my iPhone, so are my HA’s and they probably have as good or better connectivity with my iPhone as the watch. The tones of the different notifications are pretty different so just by the tone, I can usually tell what’s up, i.e., the Meross garage door app has a different sound than my pill minder app than an e-mail notification, etc.
Last I checked, the Smart 3D app didn’t offer a watch complication (widget for a watch time face). To launch the 3D app from a complication on the watch face, one needs to create an Apple Shortcut and install the Shortcut app on the watch along with the 3D Shortcut as a complication.
I’m waiting to see if my problem persists when I get a new iPhone 14. But recently I started having the problem that I can’t always launch the Smart 3D app on my watch either through a Shortcut complication or by directly launching the Smart 3D app on the watch. It sometimes goes to “Connecting…” and hangs at that spot. Other times, the Smart 3D app on the watch loads like gangbusters and is very responsive. If anyone knows what my problem might be, I’d much appreciate some guidance!
