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.
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.
School seems like a good use case for a powerbank since most people carry backpacks to school.
