Charge your phone in less time than it takes to find your charger.
And you can even fry an egg on the battery at the same time!

Charge your phone in less time than it takes to find your charger.

Just make a phone with user replaceable, commodity batteries. Then if the battery wears out after 1 year of daily charging, $5 gets you a new one.
What am I going to do with a fully-charged fireball?

i feel like that’s bad for your phone

That’s a 13C charge rate, a normal lithium battery would get very hot and puff up, possibly even catching on fire.
To safely charge at that rate, you need a battery that is specifically designed for it. High speed charging will probably be a lot more common when phones start using solid state batteries though.

i’m hoping for super-capacitors, personally

Not really. Current phone batteries has limited life cycles based on full charge and discharge, that’s why it’s recommended to not go to 0% or 100% if you want to prolong the life of the battery. The speed doesn’t really impact the health, 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.

everything impacts the lifespan and thermal load will be a big one, as well as charge rate. those recommendatiuns take a very complex set of variables and simplify it into a balance of memorable and useful.
