Hi - Samsung Note 4 (few years old now - bought on launch day!).
About a year ago the Fast Charging stopped working.
'Normal' charging from the Samsung Fast Charger with Samsung cable is very very slow - same is also true of charging from PC USB ports or any other high power AC USB charger (Anker).
Battery % will drop while plugged into the charger if I am browsing the web etc...
Strange thing is if I plug it into my car charger it charges realy fast - many times fater than any AC power supply I have tried.
I have replaced the battery with one from a Samsung service centre - twice - and used a known working Samsung FastCharger and cable from another Samsung phone that is charging fine and used other cables and chargers that work fine Fast Charging other Samsung phones we have.
I have tried it with both the Fast Charging enabled and disabled in teh Battery settings and Ac charging performance is terrible no matter what.
Also around the same time I lost USB connection to PCs.
When I connect via USB the PC pops up a message "USB Device not recognised".
I've tried this on a few different PC's & laptops - same issue.
I've enabled developer mode and checked the USB config - switched it from MTP to Charging and back again - no different.
I have also tried a full factory reset of the phone and stripped off all but essential apps.
This has made no difference - still terrible charging performance from AC chargers (but good from car chargers) and still no USB connectivity to PC's.
Any ideas???
