Anyone else's "Power-Saving Function" not really working as expected? I left my headphones turned on, then went to work. Needless to say, the Bluetooth definitely disconnected since I took my phone with me, and I was definitely at work for more than 15 minutes. Anyway, when I got back to them, the battery was completely dead.
I tested my other model by turning it on (with Bluetooth also on), and nothing paired to it. I used the timer on my phone to count 17minutes, and when I put them on my head, the ANC was obviously still on (although touch controls were not responding).
I tried turning it on but with Bluetooth off - same result.
I turned it on, and paired it, but didn't play a signal - same result.
I have a feeling that the "Power-Saving Function" doesn't apply to the ANC.
Conclusion: Leaving your headphones on with ANC also on, will result in a dead battery the next day. Leaving your headphones on and paired (even with no audio transmitted) will also result in a dead battery the next day.
