I have the battery version of the Philips 9040 model hearing aids. I’m not having any problems with pairing my hearing aids to my Google Pixel 6a.
You might want to try this to see if it helps. I believe these are the instructions for Samsung products.
Navigate to and open Settings, and then tap Battery and device care. Tap Battery, and then tap Background usage limits. The following settings will be available:
Never sleeping apps: You can add apps that will never turn off or sleep in the background so you’ll always be able to use them. You can add apps to the list by tapping the + sign, selecting your desired app(s), and then tapping Add. To remove apps, tap More options (the three vertical dots), and then tap Remove apps. Select the app(s) you want to delete, and then tap Remove.
