Terrible Battery Life on Pixel 2
-
Just installed UBT on my old Pixel 2. I too am getting terrible battery life...maybe half if not less than what I had with Android 11 installed

I apologize if this is considered necro-bumping.
Just another data point: I just installed UT on a Pixel 2, which I originally decommissioned because the USB port had become unreliable; the battery was not new when I turned it off for the last time, but not terrible.
I installed the baseline Android, including flashing the radio image (radio-walleye-blah-blah.img), before using the ubports-installer; the installation went without errors. However, after rebooting I apparently have no wifi device. NetworkManager doesn't see one, and neither does rfkill (although, it does see bluetooth devices hc_power and hci0). I wasn't really expecting much anyway, so I set the phone aside, screen off.
I came back a couple of hours later to show my wife Linux on a cell phone (!!!), but the phone was off. Odd, I thought, but it informed me of an empty battery, so I plugged it in and started it up again.
I'd attach a screenshot, except I haven't figured out how to get data onto or off of the phone yet, but I'll use my fantastic art skills to paint what the battery widget showed me:
100% | | | \ | | | \ | | | \ | | | \ 0% | | |-----------------------------------------This is with no WiFi device visible to Ubuntu. Maybe it was on full power madly broadcasting out radiation, and the Linux kernel just couldn't see it; I don't know, but it is funny, mainly because I don't need this device to work. It'd just be nice.
I suppose if I really cared, I'd start a new post asking how I get the wifi working; I probably will, eventually. OTOH, if there's something I missed that I need to do to get the kernel to see the wifi device, I'd be grateful to know. I should probably look at the dmesg logs and see if anything stands out.
I'll repeat that I did successfully flash the radio image from the Android Walleye zip prior to the installation.

Update
The issue for me, at least, is bluebinder. It sits up at the top of top consuming 154% CPU.
I have bluetooth turned off, not that turning it on does anything.
