The problem is that 6000 cycles in laboratory are not the same than 6000 cycles in real life scenarios. It would be interesting to put that battery out in the field and to see how it perform in real life conditions (assuming that they are cheap enough to be produced in large volumes) If they are really that good you are right, but there are always a lot of revolutionary advance in lab that never leave it.

Indeed: electric vehicle batteries are lasting even longer than estimated. All the constant breaks from use that the batteries get has been interestingly improving their durability (which makes me think that shutting off our phones for 1 whole day per week or even month could improve their lifespan, even for the 40-80% lithium-ion boundary keepers).

It really depends on the charge/discharge conditions that the particular test is using. You can do testing in the lab that is way harsher than typical usage or you can make it easier. In terms of this cycle testing for Li-ion I would say that typically the lab testing would be harsher than real world primarily because lab testing is done between 0% and 100% depth of discharge constantly where most people are charging their batteries much before then and only cycling them at high rates periodically.
