Phone not charging like it used to after latest updates.

My phone is at "OG7" and now when I plugin my IQ anker car charger, the phone display a message that I should use the changer that came with it. Didn't see this with the older OS. Also it doesn't charge as fast as it used to with the IQ anker charger.

So did samsung or version set the phone not to charge faster with non smaung chargers?

Any thoughts?
