Hi Andy,

This won't help you much (I don't think), but I post it to "possibly" help
you obtain the battery statistics that you "might" be able to make use of.

I don't have a pixel and for whatever reason I don't see the original post,
at the moment (I added a lot of people to my killfiles recently though),
but just as an additional set of datapoints, I've been running these three
battery-analysis apps, which I admit I don't really need but here's what
they seem to show after a few days of running in the background (I guess).

Note that the Better Battery Stats options "appear" to be comprehensive:

<https://i.postimg.cc/RCyNnMyM/battery15.jpg> More BBS settings options
<https://i.postimg.cc/fLW05BfD/battery16.jpg> Even more BBS options

Those are in addition to the "normal" battery stats on Android (AFAIK):

<https://i.postimg.cc/SsZYPCg8/battery09.jpg> BatteryBotPro options

My only point in posting this is that "maybe" the BBS apps I tested above
will provide you the options you need to obtain the debug data you want...

It was about a month ago, it took me a few days after the november upgrade to
realise things were worse, and then report it here.

Very, and you probably mentioned it at the time. My slight worry when throwing
that amount of background logging at a battery-eating issue is how much the
logging itself eats extra battery?

Anyway, I managed for a month, by disabling a couple of features I didn't
particularly need, that made the battery life live-with-able.

> Android 12 battery stats

Until Android 12, pixels displayed a battery graph similar to your "normal" one,
and could stretch back in time longer than 24 hours in a single graph (I could
get 14 days out of an old phone with all radios off, but that's not much of a
phone) since Android 13, it would only go back a maximum of 24 hours.

I guess Google found this wasn't long enough to debug whatever the power-hungry
problem was, so the built-in history got improved ... the top graph is granular
to a day, and the bottom graph is granular to 2 hour windows within the selected
day, for each time window, you can drill down and see which apps or phone
features (wifi, 3/4/5G-data, calls, screen, bluetooth, etc) were eating what
percentage of battery.

Light usage before/after new year, proved the standby battery life is at least
as good as before, the phone ran for 128 hours straight on a full charge, which
took it down to 5% remaining, estimated as 4 hours, that was with a mere 20
minutes of calls.
