Does anyone facing increasing the charging time? Initial it was charging around 8 hrs now it is taking almost double. Any tips or suggestions would be much appreciated to improve charging time.
I suggest that you check that you haven't inadvertently reduced the charging current. If you open the 'Energy' app, there is a slider bar at the bottom of the charging menu options. This adjusts the charging current.
My car will charge from around 10% to 90% overnight on an ordinary 230volt supply. It is getting on for two years old/18,000 miles and this hasn't changed. Much quicker of course on a motorway charger, typically 20 to 30 minutes.
If not the reduced rate in car, some home based charge points can reduce the charging rate if the house is getting close to the incoming supply limit (fuse or breaker)
