This article guides you through the methods of limiting the battery charging of Samsung Knox devices.

How can I prevent a device from charging a battery to 100% capacity?

To use this battery protection feature, ensure that your device has Knox 3.4.1 and above. You may enable this policy in the following Knox products:

Knox Configure - during profile creation

  2. Select Extend battery life by limiting the maximum charge when connected to a power source.

  3. Submit your profile.

This feature will only work for tablets. It will charge up to a maximum of 85% when connected to a power source. Note that after you restart the tablet, the battery will show 100% when it is charged to 85%.

Knox Service Plugin - application configuration

  1. Set Device-wide policies > Enable device policy controls to Enable.

  2. Set Device-wide policies > Device customization controls > Enable device customization to Enable.
