Slow charging --- alert, i think needed new charging cable

[lse123]

I have a Samsung Galaxy Tab S4 and charger and cable keep all in new origin condition...

Sometimes getting when charging:
Slow charging --- alert,

i think needed new charging cable, well, when spray compressed air in the plug on the tablet and on the cable, this message, sometimes disappear... well, this device has fast charging ability? Should consider a new charging cable?

When it comes to problem-solving like this, you go with the cheapest and/or easiest solution first. A new cable sounds like a good first step. I would suggest a good quality cable.

I would also suggest a cable.

The compressed air may be a bit of a red herring, but you can try a test. The next time it happens, unplug it and plug it back in without using the air and see if it starts to charge normal again. If so, then that indicates a poor connection (like a broken wire in the cable) that is hit and miss depending on things like the cable positioning.

If that's not it, it could be an issue with the charger or phone itself. I know you said you keep it in new condition, but parts still wear out over time. It looks like that tablet was released in 2018 if I'm looking at the right one. After that much use, the USB ports themselves could also be suspect due to all the connection cycles.

slow charging can be from the adapter too as well, but change the cable firstly
