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.



This is literally what a bunch of companies already do. In a Samsung flagship, if you measure the “full” unloaded battery voltage on day 1 vs day 1000 it will be about 0.2v higher after three years. This is a reserve capacity which they slowly give back over time to keep the perception of “day 1 capacity” through the first 5-10% of batter degradation.
Pixels do the opposite. They slowly reduce capacity and charging speeds as you go past 200 charge cycles.
