Usually when phone batteries are full they read up to 4.4V, so 4.18V should be around 80%

PLATINUM PHONES, I'm very confused about how Fast Charging Chargers work because most cell phones use 5volts @ 1amp so if you use a 65watt charger it will doesn't charge most cell phones faster, any reasons why? All cell phones have a built in linear charger circuit which I'm not sure what the linear charger circuit is doing which I think is changing the Pulse Width of the current being charged into the battery. The Charging system circuit that is built internally inside the cell phones has to support fast charging? to be able to use a 65watt charger, any reasons why?
@platinumphonesandcomputers
@platinumphonesandcomputers 2 жыл бұрын
Thanks, Gram for this question, Fast charging in phones is actually 2 way, the phone should support fast charging well as the charger and USB cable, The phone should have a switching charging system Ic which uses PWM with an external inductor so as to create different current by adjusting switching frequency. Then most phone fast chargers a rated up to 9V, 2A equivalent to 18watt, well as a normal charger a 5V 1A, a 65W chargers a usually for laptops. You should check if your phone supports fast charging and it's mostly in Type C phones only. Linear chargers use voltage and current drop methods, they do charge faster but produce a lot of heat, are not safe and efficient, they are mostly built-in cheap phones and Tablets.

@@platinumphonesandcomputers If your cell phone doesn't support fast charging that means the cell phone internal charging system IC is a LINEAR charging IC? I'm not sure what the part numbers are for the charging system IC chips or what circuits is inside the charging system IC chips. The theory of operation is the cell phone takes the 5vdc @1 amp and the charging system IC will convert the 5vdc@1amp to a PWM signal to "tickle charge" the battery? I don't know any other things that use those charging system IC chips other than cell phones and tablets but they have LINEAR and SWITCHING charging IC chips. The Type C cell phones is the USB-C cable type which charges the cell phone differently because the USB-C has some type of bi-directional for sensing Heat I think because the more WATTS the heat will adjust the PWM signal to tickle charge the battery. I'm not sure if you can REMOVE the linear charging system IC chip for cell phones that doesn't support fast charging and modify it by installing a Switching fast charging system IC chip? not sure if you have done this before or not these types of modifications to NON-fast charging cell phones to making them Fast charging cell phones.
