Comment on Realme’s 320W fast charging can fully charge a smartphone in four and a half minutes

assuming the phone has a way to dissipate the heat generated.

Yeah that’s a big assumption. My phone gets hot charging at 20w, don’t you think there will be heat dissipation issues at those speeds?

Chemistry has improved, but even a Tesla will not let you super charge all the time- I’d need to see some real data before I believe that a battery charged 100 times fast has exactly the same health as one charged 100x slow.

OnePlus mitigates a bunch with tech separating the battery into multiple batteries. I’m charging at 100w rn, but it’s 2 cells, each charging at 50w. It barely gets warm. -no fap.

There are many speculations that fast charging hurts the battery, but preliminary results in regard to 240W charging shows that the cooling technologies and management systems are able to handle it and doesn’t impose additional wear on the battery. There are no comprehensive independent studies on this as far as I know, and Chinese companies are improving the tech all the time, as evidenced by 300W tech recently and now 320W.

And the phones don’t charge at full speed all the time, management systems regulate it and the last few % are always delivered at low W.
