Why does my iPhone disconnect with my hearing aids after successfully pairing?

What you’re running into is actually pretty common with Made-for-iPhone (MFi) hearing aids like TruHearing, especially when paired with compact devices like an iPhone. The pairing itself is usually stable, but the connection can be dropped by iOS when the phone tries to manage power, switch between Bluetooth audio profiles, or handle background audio apps. Cutting the grass adds another wrinkle—interference from small engines, Bluetooth congestion, or even the hearing aids trying to switch back into their default “hearing mode” if they think you’ve stopped streaming. That explains why a reboot temporarily resets things: it clears out the Bluetooth stack and forces a clean handshake.

There are a few things you can try that usually help with this behavior:

• First, make sure your hearing aid firmware is fully up to date. TruHearing often pushes updates through their app. On the iPhone side, go into Settings > Accessibility > Hearing Devices and forget/re-pair your hearing aids.
• Also, turn off “Background App Refresh” for apps you don’t need, since resource juggling sometimes disrupts streaming stability.
• If you’re just listening to the radio while mowing, I’d suggest toggling Low Power Mode OFF—it sounds counterintuitive, but iOS will aggressively pause Bluetooth audio streams to save battery when Low Power is on.

If the disconnects continue, a good workaround is to force-restart Bluetooth instead of rebooting the whole phone (just toggle Bluetooth off, wait 10–15 seconds, and turn it back on). That often restores streaming immediately.
