It's a completely different scenario from your phone battery. Your phone battery gets charged to 100% every day (if you're like most people), gets discharged deeply on a regular basis, and has no thermal management. Tesla batteries are typically charged to 90% or less, with the 100% charge level being reserved for long trips, they're typically not using a particularly large fraction of the battery (most people don't drive 200+ miles every day), and there's a sophisticated thermal management system that keeps the batteries at the optimal temperature.
What kills lithium batteries is time, cycle count, heat, and extreme states of charge. A Tesla battery has a massive advantage on three out of those four compared to consumer electronics, which is why comparing to your phone or laptop isn't very informative.
Took me a little bit of searching to actually find the source, and to call it a study is a bit an overstatement, however here are some links:

You should probably link to the study.
>3 and 6 years is probably not very factual.
3 years might be early, but I have a hard time believing that Tesla has hit on some magic as far as batteries are concerned. The drain on anything I have at home is far more than what you state; my phone battery certainly isn't much good after 6 years.. But I have no idea. I guess we'll see as the current Teslas age.
