Depends on hardware. If it's a iPhone or Google Pixel then yes because of good isolation and stuff like IOMMU.
Of course system needs always be up2date with not more then a week behind Google/ Apple updates.

Also Bluetooth has a low range which make it hard for attacks against safe systems

If @security123 says it’s safe, then it must be!

Disable it along with WiFi when not in use / public space if possible.
Both can be used as for snooping or as a vector and it's pretty dangerous since low access to the baseband chip firmware ( usually requires an exploit)

Only if it's used by Apps. Else you will not see Bluetooth listed in power management (same for GPS)
New devices also use Bluetooth Low Energy stuff.


I only repeat what experts say.

Yeah the Bluetooth low power or whatever it's called has less radius so it's technically a lot safer .

@upnorth Thanks for the video.

In addition it also drains your battery

If on, but not connected, Bluetooth uses less than WiFi?
Also I find 4G Mobile Data to be most draining.

I prefer a constant Internet connection, either WiFi or 4G is enabled at all times.

Yes Bluetooth uses less energy then WiFi and the low energy Bluetooth variety can probably run a few days if not more on today's smart phone batteries(my parents had an iot device using this technology Wich ran weeks on a smaller battery then most smartphones)

I recall another Bluetooth issue called " Bluefrag " as I even mentioned it in my own mobile configuration thread, but I couldn't find a post with the patch. It was released as a Critical update in February and I somehow forgot add it in the thread. CVE-2020-0022.

Huawei EMUI security updates Feb-20|HUAWEI Support Global

We are releasing monthly security updates for flagship models. This security update includes Google patches.This security update includes the CVE announced in the February 2020 Android security bulletin.
consumer.huawei.com consumer.huawei.com
This is what I mean about check/confirm your vendors updates.

Another video about Bluetooth vulnerabilities and more easy to understand, is an issue from 2017 with a Vaultek VT20i handgun safe.
