Remote controller battery problem

Hello,

I got a phantom 4 pro in for repair last week and it seems to be working fine except the battery for the remote last for about 10 to 15 minutes until it’s discharged. I figured it would just need a new battery for the remote but somewhere i heard that they have a common problem with some voltage regulator that causes that issues. Any one else ever experienced something like that or have fixed a case like this?

Thank you
