What do you mean RC?

RC is for "release candidate".
It defines a pre stable testing channel available on any device that has stable channel.

@furkanonder said in Significant Battery Drain with Wi-Fi Enabled on Pixel 3a:

OS update channel: 20.04/arm64/android9plus/stable
OS build number: OTA-4

Here is something not normal.
Actually a device running 20.04 stable channel should be on OTA5.

See here, the last RC version is testing pre stable OTA6 (A.K.A. OTA6 "RC"):

Another thing that bothers:

Your device should have this android version installed before installing Ubuntu Touch on it :

Make sure to revert to factory image PQ3B.190801.002 before continuing.
