I know the meme format is kinda wrong. It’s also kinda right.

Bluetooth headphones when I want to use them:
Bluetooth headphones when there’s someone calling and I can’t answer because I can’t find them:
Wait, do you just keep your Bluetooth on when you don’t need it? Is that… are people doing that?
Yeah. Why not?
Because it drains your battery like you poked a hole in it?
It shouldn’t be draining like that, at least…
Even if you turn it off the radio is still powered on and scanning in the background (wifi too), unless you specifically disable that as well. The battery drain is negligible
- I did disable the scanning.
- Looked it up. Seems like it’s actually pretty low when not connected.
I never really thought about it because I use Bluetooth about once month at best. Still, leaving it on when I don’t need it seems silly. But maybe it only does when you don’t need it again a few minutes later.
For Android, don’t accept the prompt to let the speaker read your contacts and call history. Seems to stop this nonsense on my speakers.
I wonder if this has anything to do with how the bandwidth is automatically decreased when taking a call vs when you’re just playing audio. Less bandwidth means a slower but more robust connection or something like that?
I don’t think BT devices do frequency hopping. The audio bandwidth is reduced just because the mic signal is added and has to share the connection. There’s no change on the physical connection.
(Now, it would be great if there was some frequency hopping and your phones could reserve a full FM channel instead of messing with digital compression.)
That decreased bandwidth would still help to maintain a digital connection though, wouldn’t it? There’d be a weaker and slower connection as the devices get further apart, so I was thinking less demand on the connection would keep them from dropping it.
I don’t think it’s the same as what you meant exactly, but I looked it up and Bluetooth does hopping between 2.402 and 2.480 GHz.
After you establish a connection, it doesn’t hop anymore.
I have a pair of bluetooth sportbuds i connect to my work laptop for when i go in the office, and to my phone when i go for a jog. When I’m in the garage putting my running shoes on and put the earbuds in they never connect to my phone which is in my pocket. They instead connect to the work laptop…in the upstairs den…on the exact opposite side of the house. Every. Goddamn. Time.
Occasionally my phone will prompt to connect to some random earbuds, WHILE I have my headset actively connected.
Every time I am tempted to connect those and choose on their behalf. My friend, you’re now listening to the WAN show while I watch with subtitles.
Exhibit one: Aussie wanker yells at tech.
I knew who it was before I opened it.
