Apologize if the question seems silly, searched for the answers on google but couldn't get an answer, so please manage to help. I am studying detailed charging process of a smartphone battery,(software and hardware also). need to know in detail how the usb charging and TA charging works. would be grateful if anyone can explain. In Li-ion "TA/USB Battery charging", what does "TA" signifies? Is there any difference between charging using wall adapter and USB charging except the amount of charging current?if yes, what is that?
Also i asked question related to battery charging on Physics and stackoverflow, they recommended StackExchange.
