After I updated my note 9, I started having charging issues. I would wake up in the morning with my phone at 20 percent or less and check my battery usage and it shows that I either have a very small charge over the night or none at all. I have to always replug it in. I wake up some days to my phone near 80 (after replugging it in...) and it's already plugged in but it doesnt say its charging. I've done all the small things to check. New charger, different outlet, safe mode and even factory reset. All have done nothing for me. Does anyone have any idea for what this could be? I would replace my phone with warranty but I dont want a refurbished phone that i have no idea what the previous owner did to it. Thanks.
