  1. Fascinating take. I didn’t realize it was an industry goal and after having learned a lot more about car batteries and how EVs are outlasting what was expected (often <5% degradation in 5-10 years) my takeaway is that the industry standard for phones is where I need to direct my anger.

    20% loss after 2 years in a day and age when phones themselves remain useful for 5-7 years at a time easily is just unacceptably bad, especially when they are mostly designed for only one day of battery life in the first place. Worse, no one seems to measure failure rates and there seems to be no measure or goal for 100% -> full failure. I have had batteries fail on me, usually after a rapid degradation from something like 60-70% health to, well, zero (sometimes with a “revival” then working for some time at like 20-30% health). With some phones, I’d be willing to keep them for longer if it simply continued in a linear degradation pattern after that 80%, but that’s not always the case.
