How to get the current (in mA) laptop battery is draining from the charger?

I bought a new battery and a new charger recently, and since then the charger has been constantly overheating. I wonder if there is a way to figure out the current battery is trying to get from the charger. I know that the "Details" section of the battery menu shows "Rate" in watts, but I guess this is the rate at which laptop is draining battery, right?

See askubuntu.com/a/801635/295286 I've written that a while ago, and the indicator shows current usage, but that may have been added in newer version, which is on github. github.com/SergKolo/power-flow-indicator Le me know if that helps

Ah, I see. You're asking the current flow from charger to battery. That I'm afraid is impossible to measure, unless there's internal circuitry for that between power supply and battery. So, I guesa the answer to the question is "not possible".

@SergiyKolodyazhnyy ok, but still, thank you for finding time to reply!

@SergiyKolodyazhnyy You can jerry-rig an amperage meter between the wall outlet and the charger plug I guess. Also my UPS shows current drain and estimated life span. I could plug my laptops charger into the UPS and get real-time stats via USB interface. Minner--Is the laptop running whilst the battery is charging? That should be good for ~60-100 watts. Then the battery charge rate itself can be set to trickle or fast charge depending on BIOS. That adds varying amount of watts.

@WinEunuuchs2Unix Yeah, that's kinda what I was saying before, it requires having something in between the battery and charger.
