I'm not sure which particular of the latest three releases did this, but the feature at
Settings > Battery > Battery usage
This feature is more usable now. Click on a segment in the visual block-type timeline and that segment can be further examined in a second graph with finer grained time segments. Compare hour by hour battery use, switching to 'view by system' now got real utility from having felt somewhat 'crude'.
Together with the, frankly, unreal battery economy improvements recently, my p6a feels refurbished. This has unlocked the healthy habit of enabling Charging optimization limit at 80%, since now I can be sure it'll last all day.
P6a, 720 cycles, mobile network only, 4G only. RethinkDNS always on+block without.
Newpipe all day doing just fine.
