WARP: Enable Device Information Only mode

I’ve setup Cloudflare Zero Trust successfully with the WARP Client on my Android Device to access my private network. The only problem is, that it drains my battery massively. This makes this solution unusable. I’ve searched for an alternative way and came accross the “Device Information Only mode” where I hope, that this will fix the issue with the battery drain. However, in the device configuration I cannot find an option to switch to this mode although the configuration would be pretty straight forward:

So my questions are:

  • How can I switch on this mode?
  • Has anybody found a solution regarding this battery drain issue with WARP Client on mobile phones?
