after updating my galaxy a50 to android 10 and oneUI 2 . There is a major charging problem. Charging speed is very slow. 2 % in one hour. My phone was working great before update but after update it become worse.
Since your phone updated to Android 10, neither we can revert the software changes nor can be downgraded to Pie OS due to binary restrictions. You can either perform a factory reset or wait for a bug fixes update.
Please perform the below mentioned steps to resolve the issue:
1. Check your charging cable (USB cable) for physical damage such as wear and tear, bent prongs etc. If it is damaged then kindly visit your nearest service center to get it replaced.
2. Check charging, if rating is 15W or above. Kindly try to charge the device in a non-inverter socket.
Note: Kindly open Device care from Settings > Battery > Please tap on 3 dots(more option) at the top right hand side > please select settings > enable fast cable charging.
