Battery drain by bluetooth in Android 6?

Hello. I tried to use Garmin watch (Tactix Delta) on older phone with Android 6. It does not seem to have BLE, so I would expect higher battery consumption by the bluetooth. However, the battery drain is huge, like there is nonstop communication between the phone and the watch. Is that normal? Are there any bluetooth optimization settings for non-BLE devices? Would turning notifications off help?

Thanks, Jan

  • Huge battery drain on iOS as well, started around January.  Nothing has been done to fix it yet.  You need to contact Garmin customer support by phone and file your case.  They are aware of the issue, but more complaints and more diagnostics will help escalate the matter.
