batteries are not charged at a specific voltage
it depends how discharged they are
the more discharged a battery is, the more current it wants to draw and it's limited by lowering the voltage
as it gets charged the voltage climbs to ~4.2V and current drops
yessss
it's still wrong of linus to say you're charging at 14.5V
you're not
its technically correct if you only consider the power going into the *phone* since thats how the quick charge standard works
let me look at the links you posted
the first one has nothing to do with charging
that's a datasheet for a quickcharge controller
it only negotiates power with a quickcharge charger
you could hook it up to fan for all it cares
i did see a variable powersupply build based on it or something like it
but yeah thats what makes it technically correct
the battery seees something different but the phone sees voltages according the quickcharge standard or whatever its using
the phone's charging port sees *
if you take apart the phone and plug it in and poke the charging port pin with a multimeter and it has successfully negotiated a higher voltage from the charger then the meter should show a higher voltage across the d+ and d- pins
the d+ and d- pins are data pins
the standard raises the vbus pin
d+ and d- never go higher than 3.3v
Fuckin nerds
you can keep posting diagrams and shit about power delivery
but i'm not arguing with you on that
that's all correct
the point is that the phone actually gets 5 or 9 or 12 or 20 volts and then the battery does not, but the power is converted to amps and thats what the battery sees
you keep using words that make zero sense
power can't be converted to amps
power is a function of current and voltage
current is measured in amps my droooooog
im using them interchangeably because it doesnt matter
you literally cannot push amps
batteries don't see amps
they pull them as desired
you can only limit them
you could put a 200A power supply on your phone, it won't do shit
ok then damnit im going to let you prove it with sources. once your phone has 7.5w or 15w going into it how does the battery get extra power if you cant increase the voltage or current going to it
the phone cant just start radiating 10watts in heat and the battery magically charges faster based on nothing
