Yesterday I went to the apple store to try and fix an issue with my apple watch series 4. It has the 100% battery issue, shuts off randomly, drains quickly, and slowly charges. I already called support and they couldn't find an issue so I made an appointment to see an apple genius bar. I took it in and they ran diagnostics but came back to tell me there were no issues. I tried my best to convince them something is indeed wrong with my watch but they wouldn't listen. They said I couldn't get a repair or a replacement since no issue was found. I found a thread where others are having the same issue but I doubt apple support will care. Is there anything I can do? There is an issue with it I promise
