Funeral Time?

Recently my phone began to seem like it was discharging oddly and I noticed it was shutting of when the battery indicator still read around 20% so I calibrated the battery. I cant think of any reason there would be a direct relation between battery calibration and power sharing but coincidently after doing so evrytime I plugged in my charger (Samsung OEM, nothing generic) the phone initially indicated it recognized the charger with a chime and a halo ring above the home button but almost immediately charging stops and the phone gave a warning about power sharing indicating that the phone must be charged above 20%. To clarify, I've never used the power sharing feature and didn't even know about it till this issue arose. From this time on I could only charge the phone after I shut it down completely, simulated a battery removal and then inserted my charger afterwards while the phone remained off. Each of those times I've initiated those steps while some small amount of charge remained. Most recently the phone discharged completely and I cant get the phone to recognize any type of charger or USB. Lastly I began to noticed that thd phone continually mis recognized it's charger as USB and would indicated that USB had been removed even while the charger was still plugged into the wall and connected to the phone. I mention this because this says to me that there might be something which can be corrected which was corrupted or misconfiguration which could cause the phone to recognize the charger as USB. It might ve too late now that I cant get it to charge by a y conventional means though. So what do you think. Is it time to lay my Note 5 to rest already? I hope not. Unfortunately my warranty is void due to root so there won't be any exchanging. Thank God for insurance though right. If I can avoid the 5 for replacement I would love to though. Thanks in advance for your time anyone.
