Gustav_ASUSYes, using the original charger and the cable
@chintulakkimsetty Are you using the original charger and cable that came with your phone? You can troubleshoot by testing another charger and cable and see if charging rate stays the same. Also, see if it's the same for both ports if you haven't already. Finally, try charging another phone with your charger/cable and see if the second device also charges slowly.
