Hey @kennyroy! After a long time...
Samsung seems to be producing next-gen batteries, however, this is one of the most dangerous things as of now, battery explosions! Samsung Galaxy Note 7 was banned from everywhere and returned. We can overclock things even you can increase the charge rate of your phone. The battery isn't a smart thing it is still just a battery.bin file which keeps info about your phone battery. Tweaking such files can give you a lot better idea of how things work. Another thing is I do overclock the charging limits but in winter season only. If the phone is operating beyond 60' Celsius, then the phone is about to explode or will enter in safe mode by turning off itself. We have nothing smart with battery we just understand the capacity and manipulate it automatically to give a saving sense.
