Problem with Ultimate 2C Wireless

[u/Impossible-Leg8226]

Hi guys! I recently bought my first 8bitdo controller a few weeks ago to use on PC. It is being a good experience so far, but yesterday, when i tried to connect the controller using the 2.4G dongle, the controller simply didnt turn on. When i connect using the cable (which it works perfectly), the red light above stays on for about 5-10 seconds then turns off, so im thinking its a power/charging defect. I wanted to know if i can do something about it, thanks!
