I am not sure if you have gotten an answer yet. But. I can confirm, this IC is the battery charger (if I recall correctly) and the scorched component is a current sense resistor. It's got a R010 on it which denotes a .01 ohm resistor.

The missing component also looks like a resistor. And as I recall, based on the datasheet for that IC, the value should match the correlating resistor on the other side of the current sense one (the one just on the other side of the big burned out component, very near to the battery port). The underlying cause however is more likely that something else downstream is bad though if that had blown out. Could be the charging IC. Could be a bad capacitor somewhere. Coulkd even be the charge port. It might be wise to just probe around with a multimeter and see if anything in that vicinity is shorted to ground.
As I recall. The [post|847798|last person I helped who had an issue in this area, had a bunk charge port|new_window=true]. There may be some relevant information in that post as well. I believe I found the datasheet for that chip which may be helpful.
