Making specific applications exempt from optimization

Power-saving features lower the priority of certain non-essential device functions. If you do not want an application to be affected, you can make it exempt in the Power-saving exceptions menu.
  1. Find and tap [Settings] > [Apps & notifications] > [Advanced] > [Special app access] > [Power-saving feature].
  2. Follow the on-screen instructions, and select the applications to which the power-saving feature is applied.
