Your plant looks perfectly normal. This time of year most figs lose all their leaves. Your mild climate may allow the plant to keep it's new leaves all winter. Either way it should be fine.

This time of year, or any time for that matter, a fig needs lots of sun. I'd put it back in full sun. You'll need a plant that can take full sun or nearly full sun in order to get good fruit.

If it won't take full sun there is another issue. Too small pot or wrong mix. Just take care that the pot doesn't overheat next summer.

It's hard to tell from your pictures, but if you're sure you're not over-watering, it looks as though there might be a high level of solubles in play. Also, no plant likes to be root bound. The unwanted effects of tight roots include shorter internodes & loss of branch extension, smaller leaves, lower vitality, shedding of older foliage so that most growth is concentrated near meristematic regions (near branch tips), and often the inability to water properly.

I would do a complete repot, which includes bare-rooting, root-pruning, and a change of soil. Repotting and root pruning has a SIGNIFICANT rejuvenating effect on plants. Plants repotted can be counted on to exhibit greater biomass by the end of the growth cycle than their counterparts that may not have been so fortunate as to be as well cared for.

If you're interested in how to take care of trees in containers, I would suggest you read and become familiar with the information in the thread I'll link you too. I've have been growing trees in containers for more than 25 years, and teaching gardeners in my own and surrounding communities, how to improve their skillset relative to container culture. I currently have somewhere between 250-300 old woody plants, covering many dozen species, in containers - all perfectly healthy.

Your in CA. I'd plant it in the ground where it gets lots of sun. 1-3 hours of sun ain't enough.
