So twice in the last few days I've connected my watch to a Bluetooth speaker and played music from the watch directly. The battery drain during this is as expected. The moment i stop playing and disconnect the speaker, the watch battery suddenly starts draining at 6% per 30 minutes, where as previously it would drain at 5% per hour with my normal usage. I've had to reset and restore form a backup both times to resolve the issue. Anyone else seen this problem?
