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.

    Summary:

    1. When your phone’s battery health drops to about 85%, battery life shortens noticeably.

    2. When your phone’s battery health falls to around 80%, a battery replacement is recommended.

    3. When your phone’s battery health is above 80%, performance is basically unaffected.

      Yeah, just get right on that, it’s basically a trivial process.

      Not related to the video. But, this guy only has 37 videos yet somehow has 1.5Million subscribers. He also knows geekerwan. Wonder if there’s anything sus…

        Apparently this is a well-established channel in China, and they’ve just recently started translating their backlog of videos to English for YouTube.

        If you hit it right with shorts that’s not that weird, shorts are huge for driving up subscriber numbers.

        Considering the views of some of that channels shorts, it’s probably it.

      Was there nothing about how fast charging impacted how quickly it reached 80% SoH?

        He only checked battery health loss. Not the speed of capacity loss until 80%.

        The end result, it does not matter. Use and charge your phone how you would like to. A few percentage for keeping the battery at 20-80% only to have a reduced capacity from the very start does not make sense.

          Well. I mean that’s like THE most important thing. Charging at a higher C rate is going to cause increased wear on the battery and less life. That’s why most phones are limited in that way.

            He did test Iqoo phones charging at 120W. And the wear was less than slow charging. So, that should answer your question. But, he did ask to comment any other tests people wanted.

            You can drop one on this video if you want to.

          It makes sense to me IF it actually works.

          Having extra capacity when a device is brand-new isn’t a huge boon, but having stable capacity over the long term would be. At least for me.

          Of course this will depend on your habits. If you replace your phone every year, then it doesn’t matter. If you’re a light user and only go through a couple charge cycles per week, it’ll matter less than if you go through 1-2 cycles per day.

          Personally I’m at around 1 cycle per day on my current phone, and after nearly 3 years (over 1000 charge cycles now) the battery life is shit — much worse than just 80% of its original battery life. Performance also suffers. With my last phone, I replaced the battery after 3 years and I was amazed at how much faster it was. I didn’t realize throttling was such a big problem.

          I might replace my current battery, but it’s such a pain, and it costs more than my phone is realistically worth.
