It would be 90% and then in about 20 mins it would go down to 0. This just started happening. I have no heavy use. Just Uber driver, doordash and grubhub chrome redditt and sometimes Youtube. That's it. no games no continues streaming nothing that would justify a rapid drainage. I have followed Youtube to get answers and have done everything like apps in deep sleep, always on turned off, adaptative bigness turned off. refresh rate down to low. When I run a Care check everything looks good. Not sure what's happening. I though I might need a OS upgrade because I had a version 7 and so I upgraded and still same thing. Anyone have this issue? Will battery replacement help?
