To add on to what others have already mentioned, the PDF has more details on bisphenols which paints a less dire picture than the press release.

1. There are no EU-wide regulations restricting on BPA concentrations in electronics devices.

2. The ECHA has proposed for limits is 10mg/kg which is also used for the OEKO-TEX Standard 100.

3. In the study's evaluation criteria, for parts to achieve a green rating for bisphenols, the concentration has be below 0.8mg/kg for parts touching the skin and below 10mg/kg for parts not touching the skin.

4. 69% of the tested samples achieved a green rating for bisphenols.

So while there is a gap in regulations ensuring a safe baseline for electronics, the majority of the tested headphones are doing okay as far as bisphenol exposure even under the proposed guidelines.

The black and silver and white and silver sample photos look like they may be using HASL surface finish (aka, solder).

If you're handing out business cards with a HASL finish, make sure to spend extra for the lead-free version.

Huh, that's quite a bit more than I would expect. You already ruled out the 12V battery in the other thread, but there could be some other factors that would keep your car awake.

Does it only happen when you park in front of the garage at home, or does it also happen if you go out somewhere? For example, it might be struggling to connect to your WiFi at home (if you set it up with your home WiFi credentials) to download updates or upload telemetry, which would keep it awake longer than normal as it tries to make do with kilobits per second of usable bandwidth.

While the idle draw is relatively high on Teslas compared to other EVs (even without sentry mode enabled), 7.5% is quite high. I track my stats with Teslamate and it estimates typical SoC loss of 1% over a day.

What I have seen is that the BMS may update its SoC estimate after driving, and I've seen it adjust the estimated SoC up or down by as much as 5% in some cases.

I get that from a planning perspective, it still stinks to have range than you thought you did an hour ago, but it's not all that different from the variation you might get with an analog dial on the gas tank, just that it's much easier to notice and track when it's digital and showed as a precise number.
