Disable "Charging slowly" warning When charging my phone, a LG K8 V, I get the message "Charging slowly: Use the charger and cable that were provided with this phone, or check the cable is properly connected." The charge rate is fast enough for my purposes (I haven't noticed an actual slowdown) and everything's plugged in properly so far as I can see. But, the warning is annoying because it pops up every time I plug in the phone and I need to manually dismiss it to do anything with the phone, even to answer a call. How can I disable it permanently?
You will find a good explanation of charging slowly in answers to this question Android phone &quot;charging slowly&quot;: How to make it faster

  ...charge rate is fast enough for my purposes 



It is not what you feel, it depends on the power as you can see from Andrew's answer there. Depending on the power the toast is displayed


Try methods suggested there to improve charging power. If that doesn't help, there is nothing you can do to prevent the notification from showing up


Edit: What finally did work for OP was a thicker Charging cable as was one of the recommendations on the linked answer
