MacBook Slow After Battery Replacement

Block Image

So I just replaced the battery of my MacBook Pro 15 Inch Retina 2015 version.

Since then the computer is REALLY slow.

Right after I replaced the battery, I did an SMC reset....

The Battery I bought is definitely original, I bought it through special connections in Shenzhen so its not a cheap crap battery.

Does someone have a solution to this or does someone had this problem before?

Please help <3

I think you need to look at the battery charging logic. Download this gem of an app: CoconutBattery lets see what it tells us. Adding images to an existing question

Your system is in safe mode which is when the CPU's clocking is reduced to prevent it from overheating. This is controlled by the SMC and if one or more sensors are failing this can cause this. CoconutBattery will allow us to see if the battery sensor is failing as well as SMC.

Looks like we'll need to look deeper ;-{

OK, down load this app: TG Pro Lets see what it tells us. Post a screenshot of the main window (you may need to resize it so all of the sensors are visible)
