I experienced some huge issues with the battery of my S9 today. I was in a videocall and my phone was charging normally at around 75%. Then suddenly the phone rebooted itself out of nowhere and showed a 0% battery status. Once rebooted, the phone immediately shutdown itself again, I guess as a reaction to the reported low battery status.
Once connected to power again, it is now charging up normally without any issues so far.
Is this a possible software issue? Has anybody expierenced something like this before?
