Light bar stays on?

I have a ps4 days of play edition with the matching remote, I checked the model number and based on the fact it has the two light bars I know it’s a newer model remote (I also found out with a fix I tried), I was charging it on a portable charger, which I’d done before with my gen 1 remote, and after a few days of doing that I noticed the remote would tweak. First it started with the ps4 constantly showing it charging even when it wasn’t, then when I unplug it it’ll stay connected normally but if I turn the remote off it thinks that it’s still charging as the orange light on the light bars turns on. If I try to reconnect the controller to the ps4 without a cable the white light will blink once or twice and go back to orange and after repeated tries the light will freeze white. When I plug it in the light goes away and turns orange again and if I turn on the remote it turns on normally and pairs and works fine. At first I thought it could be a battery issue, I haven’t had it very long (6 months max) but I thought maybe the portable fried the battery so I bought two replacements and replacing the battery only fixed the problem that it didn’t have any charge and wasn’t accepting it anymore. I’ve tried pressing the reset button on the back, unpairing and repairing it, I’ve tried everything and nothing works. Help?
