Hi Sis65! It seems like you might have a defective part. You can go through my steps below. I included some steps that you said you already tried for people in the future that may have the same problem. Happy iFixing!
=== 1. ***Battery Calibration and Charge State*** ===
-
* ***Pre-Charged Batteries***: Yes, it's possible for a new battery to come with a partial charge, often around 30-50%, to keep it stable during storage.
* ***Battery Calibration***: Sometimes, macOS and Windows need a cycle or two to correctly recognize a new battery's charge capacity and status. Try letting the battery drain completely until the computer shuts down, then charge it back up to 100% to help with calibration.
-
=== 2. ***MagSafe Adapter and Connector*** ===
-
* Check if the ***MagSafe adapter*** is working correctly with another compatible Mac, if you have one, to confirm it’s not the issue.
* Inspect the ***MagSafe port*** on the MacBook for any dust or debris that could be preventing a proper connection. Cleaning this gently can sometimes help restore proper charging.
-
=== 3. ***Battery Cable and Connections*** ===
-
* Double-check the connection of the battery cable inside the MacBook. Ensure it's snug and fully seated in the connector.
* Sometimes, connectors can loosen slightly if there’s any dust, so a secure fit is essential.
* Running Windows might add complications, as it has different power management than macOS.
* Since the report mentioned "Connected Standby Not Supported," it suggests that Windows doesn’t fully recognize the low-power sleep mode found in macOS. While this shouldn’t stop the Mac from charging, it can cause issues with sleep mode, battery reporting, or charging behavior.
-
* Try booting into ***macOS*** to see if the charging issue persists. If macOS recognizes and charges the battery, then the issue might be related to the way Windows interacts with the MacBook hardware.

* Try booting into ***macOS by holding Option (⌥)*** or ***Alt and*** selecting the option that is not Windows 10, to see if the charging issue persists. If macOS recognizes and charges the battery, then the issue might be related to the way Windows interacts with the MacBook hardware.
=== 5. ***Software vs. Hardware Issue*** ===
-
* If macOS also fails to charge the battery, it could be a hardware issue. In that case, here are a few next steps:
** ***Try Another Battery***: Although unlikely, some replacement batteries are defective out of the box. Testing with another battery (if possible) might be worth considering.
** ***Check the Power Controller Board***: In some cases, the power controller circuitry might have failed, especially if the battery was previously causing power issues. This is typically a repair for a technician but can be an underlying cause.

Hope you get this issue resolved! I have quite a lot of knowledge related to Bootcamp, so hit me up if you still need help.
