TLDW; No

Basically the video is testing phones with varying charging speeds and how much battery degrades after 500 charging cycles. Also, the affects on performance after battery degradation at 5:37

Timestamps of some tests:

  • Test results for different charging speeds at 3:06
  • Storing batteries at 1%, 50%, 100% at 3:43
  • Battery performance at 4:42

After 6 mins he talks about why the tests took 2yrs and how they did it 3 times.

But is there an advantage on artificially limiting your battery to 60% rather than charging to 100% and having 40% degradation at the end of the lifetime? In the second scenario I start at 100% capacity that slowly gets lower and lower whereas in the first scenario I have only 60% from the start and still some (although much less) degradation.

    The advantage is that I can occasionally charge it to 80% or 100% if the situation demands it.

    And if it can run a 6 hours with 60% then I would like to preserve its ability to hold on for an entire day at 90% if the situation demands it. I often deal with this at school. A half day of back-to-back classes? 40% is game. But a schedule that has more than a 6 hour gap that I'd likely fill with studying from PDFs and gaming? Then a good 90% is needed.
