uConsole charged very slow and can’t update

I charge my uConsole yesterday for 6 hours and it has only charge to about 13%. When I try to update raspberry pi, I got this error message: “Error Updating Package Data: Cannot refresh cache whilst offline” but my wifi is already connected.

UPDATE: I figure out the charging issues but I still can’t update my raspberry. Is this normal?

More information, please. Logs, screenshots and etc.
