@furkanonder said in Significant Battery Drain with Wi-Fi Enabled on Pixel 3a: 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"): https://forums.ubports.com/topic/10475/call-for-testing-ubuntu-touch-20-04-ota-6/ Another thing that bothers: @furkanonder said in Significant Battery Drain with Wi-Fi Enabled on Pixel 3a: Device build description: lineage_sargo-userdebug 9 PQ3A.190801.002545 test-keys 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.
