BYD’s Second-Generation Blade Battery Makes Western EV Tech Look Ancient (insideevs.com)

The second-generation Blade battery can charge from 10-70% in just about five minutes and from 10-97% in under 10 minutes. More impressively, the company showcased the battery charging flawlessly from 20-97% at -22°F (-30°C) in just about 12 minutes, only around three minutes slower than it charges in normal temperatures.

...

The EV was plugged in at 9% state of charge with 93 kilometers of range (57 miles). In 9 minutes and 51 seconds, it charged up to 97% with the range prediction in their gauge cluster displaying 1,008 kilometers (626 miles). This is likely calibrated for the China Light-Duty Test Cycle (CLTC), which tends to be more optimistic than the Environmental Protection Agency (EPA) test cycle in the U.S.

Still, these charging speeds are way faster than the 20-40 minute charging stops on the latest EVs in the U.S. The new BYD EVs can basically recharge in nearly the same time it takes to refill a gas car. Even the new 1,500 kilowatt (1.5 megawatt) Flash charging stations are arranged like a traditional gas station for cars to quickly drive in and drive out.

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 same 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 when 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.

Though I have no idea how anyone would go through 100% of their battery before they go to sleep for any less than 2-3 hours that it takes to "slow" charge a phone... I guess using the phone as a dash cam would do that as an example.
