Comment on BYD’s Second-Generation Blade Battery Makes Western EV Tech Look Ancient

  Do I understand correctly - you charge to 80%, have zero degradation, but also only use 80% of your battery at most, because of that.

  Your fast-charging friend, meanwhile, has been using all 100% down to 93% battery for these 1.5 years. Maybe, in a bad scenario his battery will degrade to 80% in 1-2 years and he’ll start using only 80% of his like you?

  Where’s the upside in this, unless you’re both planing to use dame phone in e.g. 5 years and you might get ahead in battery capacity finally?

    There are many upsides.

    One is my phone survives longer and whem I sell it second hand to a less fortunate person, they get a phone with a battery in perfect condition.

    Another is that my phone holds more value.

    Another is that I remove a worry from my head. I’m no longer questioning whether I am destroying my battery.

    Though I don’t see the upside of charging to 100%. I literally dont need to. An 80% charge lasts me like 3 days so I usually charge every 2 days in case I need my phone.

    Where’s the upside in this, unless you’re both planing to use same phone in e.g. 5 years and you might get ahead in battery capacity finally?

    Not EVERYTHING is about having something better than someone else, jesus, I’m so tired of this mentality of “I gotta have just a little more than that other guy”. Why should I try to get more if I literally don’t need it?

    Why would I want my phone to charge in 5 minutes if I spend 6-8 hours sleeping myself???

    Why would I want to charge to 100% if 80% lasts me 3 damn days? (And that’s if I use my phone a decent amount)

    If you need 100% charge daily by all means charge to 100% at full fast charging speed but I literally don’t need it.

  Every time I’ve seen someone test this hypothesis - as in doing a long-term experiment with the specific purpose of testing whether fast charging harms battery health - the result has come back that it doesn’t make much deference at all

  It’s also worth pointing out that every battery is different and apps like Accubattery are imprecise. It’s entirely possible that your 100% and your friend’s 93% are actually exactly the same. It’s also possible that their battery would have displayed 93% when brand new

    I crossreferenced my testing a lot though I cant 100% guarantee what I found is accurate.

    Though I can say this: I don’t think built-in health monitors in phones are worth a damn. My gran’s phone was showing at 100% health when accubattery was at a whopping 73%. Testing the old and new battery, the new battery held up just about 30% more time than the old one on youtube playback.

    I did other things that I wont get into

    This is why I chose to trust accubattery and pretty much invalidate other testing in my head. I know it’s one single test and sample but this is my information and I trust it at lleast for now.

  93% after 1.5 years works just fine for most users who do not prioritize longevity or sustainability over convenience.

    It’s not even about convenience. They just have fast charging on by default and they never bother to check if they need it and what are the ups and downs

  Some phones get over 70° while fast charging, which is not helathy for the battery first.

    Yea the temperature change is what kills afaik.
