Learning through experience is sometimes time consuming.
Good microscope should be of help in these cases.
Good work!

and not to forget about quality flux. Cheaper flux and soldering paste is the issue of ic's not soldered properly.

ACOK 6V is not good, it should be 3.3. Replace BQ24780S charging IC.
