This component near by the charging port came lose during home repair :( now phone is not charging and stuck at 1%, when touching component phone starts charging. What is the best way to fix it? I'm thinking of conductive glue as the first option before I start thinking of microsodering it.
The size of the metal pin on the video is 0.4mm

This component is a FET and it is on the line that communicates charge state from the battery to the CPU. That’s why you see the charge status stay at 1%.
Given the size of this transistor, I don’t see how you could successfully apply such a small amount of conductive glue and have it work successfully. Additionally, there is a good chance that the actual pad was lifted off the PCB which would render conductive glue useless.
The best way, and proper way, to do this is via a micro-soldering repair. Depending on your skill level, I generally don’t recommend this type of work for a DIY’er. It’s easy for things to go bad really quickly if you don’t know what your doing.

I think it's this transistor http://rohmfs.rohm.com/en/products/datab...
Are you suggesting to remove it completely and reset it back to make sure all pads are soldered?
Yes, that's the right transistor.
If I had this logic board on my bench, I would start by inspecting it under the microscope to see if the pad is lifted. If it looked good (or I couldn't tell), then I would try to reflow it. If that didn't work, then I would remove it, correct any pad damage and then replace it.
