What is the risk of using the EV mode continuously in Kia Niro?

I have recently purchased a Kia Niro and I am curious about the EV mode. I have been using it constantly, but I am concerned if there are any negative consequences to doing so. Can someone please explain the risk of using the EV mode continuously in Kia Niro?

Constant use of the EV mode may potentially decrease the lifespan of the battery and result in higher maintenance costs in the long run.

It is recommended to use the EV mode only when necessary, as continuous use can lead to faster battery degradation.

Using the EV mode continuously may also impact the car's performance and reduce its overall efficiency.
