Im haveing some issues with my phone fastcharging and havent found a permanent fix as of yet. Restarting my phine lets it fast charge for one cycle then it revers to taking 7 hours to charge fully. Iv tried using my main charging setup (apple usbc plug with an anker cable) my powebank and the og samsung setup. The former charges my ipad without any issues.
Ensure fast charging is enabled on your phone. Wipe the cache partition, and try to charge in safe mode.
im still haveing issues with fast charging and unsure how to wipe the cache on my device or enter safe mode on it.
