Charging problem after upgrade to IOS 15 (Ipad 6th generation)

I've recently updated my ipad's IOS to 15 but after that it will charge randomly or never when connected to the power. Yesterday I've updated it again to IOS 15.2 but **problem still exist**. I visited many sites for this problem and one of the options was to hard restart ipad. But as you know I must hard restart my ipad every time I want to charge it! I changed cable and cleaned the port but nothing changes. This link shows **I'm not alone** with this problem after IOS 15. Do anyone know **permanent solution** for this problem? I'm sure that my ipad's port or cable have not any problems and the problem is from last update. **UPDATE:** My device’s board was burnt! After the update:) So I changed the board and the problem has been solved
