Listening to music on the a2dp profile drains how much more battery compared to listening to music on the normal audio profile?
I don't actually use this headphone for calls, but only for streaming a2dp music and audio from my computer.
I believe the a2dp profile send audio at twice the quality/sampling/bit rate (I'm not sure the exact technical term) than that of normal Bluetooth audio. When I'm receiving a2dp audio on my Bluetooth earpiece, is the battery life cut in half?
Because I have a headset that is advertised to have 11 hours talk time, but I'm only getting six hours roughly of a2dp audio time before the battery is depleted. But I can't rely on this data because sometimes the advertise battery life is not reality (due to poor lithium-ion battery storage conditions, manufacturing defects). And I haven't been patient enough to do a non-a2dp battery life test, because the listening quality is so much inferior.
Although various sources on the Internet say that the a2dp profile drains more battery, some say even twice as much, I haven't found the technical specifications for a2dp that detail its battery usage. Does anyone have some insights or technical specs?
