can you explain why my s5 neo after flashed turn off charger when i got 95% and i see is battery used 10sec and now fully charged, in the night i dont unplug, maybe the usb cable bad? the cable i used for a5 2016 before november 2018 same issue , stopped charging when reach 52% doesnt matter, but in the phone usb plugged in and dont unpluged m and yeah when i turning on with power supply to the phone when phone was off, i put charger and turning on all time without plugged sound when phone booted up , but the one day i heard sound when booted up from usb cable to connected the charger via phone. maybe the usb cable bad? sometimes charged without problem. and when i got 29% percent the phone still does charger sound when i plugged in 20% but i dont plugged in 29% i heard sound
