I have the Galaxy Note 5 and have had it for a year, this month. Last week my phone started doing the same thing that yours is doing. I had to buy a wireless charger, which cost $70.00 and when I try to charge from the wireless, it just keeps beeping repeatedly, and say Fast Wireless Charging, then 2 seconds later is says, Wireless charging paused. Sprint told me that the USB port was bad, but I have gotten it to charge with other cords, but it will not stay charging for more that 10 or 15 minutes. Then it stops. Through out the day, my phone thinks it is charging while I am talking on the phone, sending an email, texting, the screen keeps going back to the charging screen, and it isn't even near a charger. The dam Gear VR program keeps trying to install, and I deleted all of it from my phone at least 4 or 5 times. I can't get anything done on my phone anymore because, the screen won't stay in texting, email or what ever software I am in, it is constantly making that beeping noise it makes when you first start to charge it, and even when it says it is fast charging wireless, an hour will pass and I will check it, and it will show it is charging, but it will still be at the same percentage it was when I put on the charger. Can someone please help me stop all this chaos.
