Hardware Charging problem-- over heating

Hi,

i have got a problem in the charging circuitry of my LG G2 LS980. The problem started as i left the phone on charging over-night and it was super hot in the morning. Also it was not charged to 100 %.

Since then its temperature is too high when ever i plug in the phone for charging. also the rate of charging is decreased significantly. it takes upto 12 hours to charge. I opened it up and i found that the component highlighted in the picture gets very hot. i want to change this component (which appears to me as a capacitor), but nothing is written on the component (no rating or part number).

Can anyone please comment what it is ?

It is in the charging path so it must be a current limiting diode, capacitor or something.

Please advise something for it......
