Thicker glass, stronger metal couldn’t save Galaxy S9 in SquareTrade’s professional drop tests.

It depends on the stresses in the particular piece of glass and exactly how the phone is dropped. Some of them can break by dropping 2 inches to a feather bed onto the back of a TPU case, others can survive a 3 foot drop onto the screen. If they annealed every screen properly it would cost another $100 or so per phone. That's why bullet-proof glass costs so much more than window glass - the materials are pretty much the same, the process is completely different.
 

Perhaps it may be listed on their website somewhere, but other than the bend test (assuming they used an Instrom machine or equivalent), none of the tests looked like they would actually be able to measure the amount of force required to cause breakage. It's likely they are evaluating how much damage they observe after the fact, which is not really a complete test in my mind (I'm a test engineer). Not saying there is zero value, but that the tests are more of a binary result, which has limited value.

I can't see it costing anywhere close to $100 to anneal the glass. Perhaps if they did it one at a time, but any production process would reduce that cost significantly. Especially since the glass is quite small. A large piece of glass may only allow one piece at a time in a controlled kiln. But small piece like this would either be done as a continuous process (on a belt that runs through a kiln) or in batches. Both of which should make it really cheap to accomplish. That said even if it's not annealed, it's likely the internal stresses would be similar from one screen to the next as the manufacturing process would be the same.
 
Don't drop your phone and don't rely on BGR for unbiased stories. Get a case you're confident in and go on with your life. Also, like someone once said there's no point in having something if you have to baby it and keep it safe. Whether it's the most fragile or most durable, stuff is gonna happen. I haven't put a screen protector on a phone in years, and I'm usually without a case. I love how the phone feels in my hands and if it happens to break then so be it.

Bullet proof glass is higher cost than window glass. Window glass is glass, however Bullet proof glass is usually polycarbonate or a layer of glass mated with an external layer polycabinate.
