Slow charging after replacing charge controller

My phone was having what I assumed was a thermistor issue. Stated that it would charge when temperature returned to normal. I replaced the charging board with authentic part from ifixit. Replacement was accomplished without issue and phone worked normally afterwards. It only worked for about a week or so and is back to doing the same thing. Wired or wireless it's charging slowly or not at all stating temperature too low. Multiple chargers cables all same result. These same chargers cables are used on another s21 without issue.

@adambell9015 there are a few more thermistors on your phone. Besides the one in the charging port, you also want to change the battery. After that, there is one (or possibly two, I'd have to check the schematic once I am off work) on the main board.
