  • Yes, but to increase longevity energy density goes down substantially. Manufacturers (and many users including myself) would not make this decision for something as weight and size sensitive as a phone. The lithium ion batteries currently used already last for 2 years after all and are relatively small. A single model S battery contains 7104 individual cells for comparison. Further, lithium battery recycling has made substantial progress over the last year and will already need to be done at scale when higher volumes of EV batteries have reached their end of life. The impact of the of life phone batteries even from the entire world will be dwarfed by that of the 26 million EVs already on the roads today with thousands of cells each (or equivalent if using prismatic cells).

    Some cars use LiFePO4 batteries for the superior longevity. But the range is reduced to somewhere between 1/2 and 2/3 their lithium ion counterparts. The industry is moving away from this trend in recent years in favor of traditional lithium ion with a software limited charge/discharge range.



  • The chemistry from holding that last 20% of charge for a while is what causes the degradation. The BMS can tell the system to stop charging before it’s full but it can’t do anything itself to prevent the cell from slowly being degraded by full charging.

    This is is a problem that occurs on the order of years and that’s why the EV companies care but phones historically don’t. More easily replaceable batteries is the real solution here, not software stopping you from fully charging.






  • To be fair to Netflix before other networks took streaming seriously they were charging very little to license their content on Netflix. That’s why it had everything and was so good to be better than piracy. The royalties from Netflix couldn’t be enough to fund these networks. Even Netflix themselves as the studio has struggled substantially promoting these price hikes and the effective recreation of cable TV.

    As they lose more of the licensed content they’re forced to focus on their own. Unfortunately for the just part they can’t compete with constant new mediocre shows and movies. The streaming industry as a whole has lost sight of what made it popular in the first place.

    I assure you it is much, much worse than dominos. It’s like making a pizza with Cheez Wiz instead of real cheese. Considering the ingredients of provel cheese are all nice on their own is quite the feat.

    This is certainly a distinct style of pizza, as much difference as Chicago style is from New York. Unlike with those I have no idea how anyone thought this was a good idea.





  • Anything over $100k is plenty to live, travel, and invest with if you don’t plan on having kids. There’s a point where it’s time and experiences that are more valuable than the money, so I’d prefer fewer working hours or more engaging work than simply just salary increases. I’m certainly happy to receive bonuses and raises, but as an engineer who has never made under $100k/yr the money doesn’t change anything about the way I live and enjoy life (note that I don’t have expensive tastes and carefully watch for lifestyle creep).


  • AA is the last United States based airline to even have one. This move is an industry-wide trend now that lie-flat business class seats are standard. Business class has gotten much nicer in the past 10 years and taken away the customers that previously would have flown in first.

    I’d rather fly Qatar qsuites or many other si-enclosed business class seats than the first class ones remaining on European airlines like British Airways, Lufthansa, of air France. And doing so is a fraction of the price.
