[Q] Note Battery life with Bluetooth Headset(Music playback)

please share your experience regarding Note's Battery life with Bluetooth Headset, for music playback
Is it good going for a blue tooth headset for listening music?
or wired headset is better?
Good sound quality... Good battery life... Go for Wired headset.
I have not found any issues. Battery use is obviously higher, but not so bad that I would not use it. I only use the wired phones when I am going somewhere with no bag and need a 'pocket' solution, as I find the wires irritating.
I have found BT to be choppy on every single device when the set is on the opposite side to my body. I think it is mainly me, and may be because I need to lose some weight (all that fat is getting in the way of the signal ). I have my phone on my left hip and every BT headset has the receiver on the right.
Interestingly, after rooting, removing bloatware and flashing the abyss kernel, I have no more of these issues. Unfortunately I do not know which of these made it better, but I suspect the kernel.
I use Bluetooth to listen to music during commute, I don't think you need to worry about Bluetooth usage affect the Note's battery life too much. The Bluetooth device will run out of battery long before the Note does.
Music quality through Bluetooth is not as good as through wire, but it is more than acceptable for use out and about in noisy enlivenment. Beside to be able to change volume and skip track without touch the Note is so convenient.
Hi, The bluetooth is always activated on my GN and the battery life stays great! I use a2dp bluetooth everyday to listen to my music in the car and with my bluetooth headset and i was surprised because it's the first Samsung battery that doesn't gets out of power until i get back home (I had galaxy Mini, Galaxy Ace, Galaxy S and S2...) So go for bluetooth headset, don't worry about the battery life you will be surprised about it
Finally, sorry about my english, it's not my native language
As a long time user of my mw600 Bluetooth and testing over months i can say that after listening to music for 10 hours straight my Bluetooth was only responsible for 2% of my battery drain. After listening to music for that long my battery was at 50%.

Battery life seems unchanged, I have two Bluetooth stereo headsets a cheaper generic and the Jaybird Freedom. I use them mainly for audio books and music listening for two or three hours at a time. Occasionally I will also use the data connection and I think the battery drain is almost the same as if I'd not be using the headsets.

Wakelock question

I've read a bunch of stuff on wakelocks but one thing is still confusing me. Do the wakelocks I see on my phone through GSAM battery monitor always indicate a problem?
Reason I ask is at the moment I have 22minutes of AudioOut_4 wakelock. I've read that specific wakelock is the music player but I have been listening to music, which I would assume causes the phone to stay awake.
So is that 22 minutes an issue that I should be investigating or is it a "valid" wakelock that has been caused simply by me listening to music so I can happily ignore it?
It's perfectly normal. Whenever there is an audio output.

Anyway to disable Bluetooth notification?

Just got My Gear 2 neo and the battery seems to be draining rather quickly today and i think its because of the constant Connect/Disconnect with my phone.
Im a Propane delivery driver, so im constantly getting in and out of my vehicle. Ive noticed my screen keeps coming on to notify me of the bluetooth connection status.
Anyway to disable this?

wifi/data shuts off when using music apps

When i'm listening to google play music, radio.com or siriusxm app either on wifi or cell data after about 15 min the radios turn off. When i wake the phone, it restores the radios and all is well, at least for the next 15 minutes. Is there a setting or an app that rectifies this issue? Thanks.

Bluetooth constantly disconnection when idle

Is anyone else having issues with Bluetooth disconnecting while the phone is idle. I've been finding that my aeropex aftershocks keep disconnecting while my phone is idle although if I'm actively listening, they stay connected the whole time. I've been able to duplicate the issue with my pixel buds as well
