I saw this on infinity for Reddit earlier, I don’t know if there’s a workaround for this or not.

Where is that mentioned? I can’t find that in the article
It’s mentioned in the linked article about Find My Device.
This is what it says
I don’t know that means Bluetooth will be running when the device is off. “Specialized hardware” could mean a full Bluetooth modem on backup power, but more likely it’s means there’s a low power beacon. Would be interesting if anyone does a teardown of the Pixel 8.
For non-Pixel 8 devices, definitely not. I assume “Offline” refers to the case where your device doesn’t have WiFi/LTE, but can still use Bluetooth to communicate with devices that do.
I also couldn’t find a mention, and it definitely does not make sense (and likely isn’t even possible) to run Bluetooth without Android itself running
Maybe this line is being misinterpreted?
It’s definitely possible. It may be using specific hardware to do the powered off tasks. Or it never be truly off, a small os running to managing these powered off tasks.
The second is more likely, it’s cheaper and easier. It can also be applied to older devices and requires less integrated design.
That doesn’t say that. Although the article linked from there does, for Pixels.
even with a dead battery? how? there must be something ‘turned on’ to send bluetooth signals or is this magic?
Not necessarily, there are lots of completely passive beacon technologies. I seem to remember reading a few years ago about beacons powered by Wifi signals.
Obviously you also need other phones to be able to pick up those signals so it might take until phones with Android 15 become commonplace which might take a while. But it’s definitely doable.
I suspect it still draws battery power, but extremely small amounts. Few mah left in the battery could power a BLE beacon for weeks. There would be some limit to this as draining the lithium battery too deeply will damage it.
