Help Galaxy Tab Pro Battery Drain Fast and Charge Slow with Flickering Camera Flash

Dear Android Community

I have a Galaxy Tab Pro SM-T520 10.1 inch Android 4.4. Problem:

- The battery runs down very fast and also suddenly according to the standard battery meter on the home screen.

- The battery takes a very long time to charge.

Additional Symptom: the camera flash flickers occasionally when charging.

Does anyone know how I can start to fix this or any experience with this sort of issue. I’d prefer to fix it with the community’s help than send it for repair so any help is much appreciated!
