It may or may not be your problem. I could be a faulty charger unit or it may have been subject to something which caused its failure which isn’t the fault of the manufacturer. For example water incursion causing a short, lightning strike or voltage spike frying the circuitry, wires which have been pulled and disconnected internally etc.
This is one of the challenges when products move towards being driven by electrical energy, including batteries for convenience. The cost of battery replacement can be more than buying a new product which creates enormous eWaste.
The other challenge with many products is the batteries can’t be changed (are sealed within the device) or are very difficult to change without specialist tools. When a battery say fails/no longer keeps adequate charge, the whole product becomes eWaste.
With more an more importance on waste minimisation and recyclability to reduce depletion of the world’s finite resources, manufacturers should be required to make products which can be readily serviced and repaired (this is a subject of another thread, the right to repair).
