No free UPS on that RPi Zero though... Whereas the android phone will happily run a day without power.

That's very true, I forgot about that.
I think I have an APC Back-UPS 425VA (or 600VA) that takes care of that for a sprinkle of RPis, a firewall, an access point and the ONT outside. I like to keep my connectivity during the very brief power outages (underground power).
I've been meaning to try using an Anker portable battery as an extended-run UPS, but haven't tried it, and I don't know if it'll keep the USB port powered on continuously.
None of Anker's batteries charge and provide power at the same time so they cannot be used as cheap UPSs.
I think you'd be better off looking at some of the DIY electronic battery things - eg WiMos battery shield or adafruit powerboost (https://www.adafruit.com/product/2465) and a LiPo battery, but they will only provide ~1 Amp.
Yes, but there's an off the shelf solution for Raspberry Pi battery http://lifepo4wered.com
I love that it's open source hardware: https://hackaday.io/project/9461-lifepo4weredpi
5.5 Watts:
My Dell XPS13 with a bunch of browser/slack/java processes on Linux. (it's below 4W at idle)
40 Watts:
My 6-year old Xeon E3-1230 (v1) with 14TiB usable ZFS and 32GB of ECC RAM.
Also, if you're really going for very low power, I'd suggest an RPi Zero W instead of some Android phone. $10 @ MicroCenter and you can install pretty much anything your heart desires from standard Raspbian repos. I can't even measure it's wattage at the outlet with my power meter.
