My galaxy s10 suddenly isn't charging properly. I set it to charge this morning and it reached 85% and did not increase and in fact it started discharging. I tried safe mode, and deleted a few apps but still the issue persisted.
I powered off the phone and then it charged to 100% no problem, that too fast charging.
Thinking this might be a firmware issue, I factory reset the device, but after setting it up again, it still won't fast charge. It has been plugged in for 40-45 minutes and barely increased from 70-76% battery.
They are. I've tried with another Samsung charger as well (included with S9+). If it was a cable problem, it would not charge while switched off, right?
