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!

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.
