Google services eating battery. Anyone else?

One thing I noticed is that when I take my sim out and use it in another phone, then battery lasts forever. I'm not sure if that makes any sense.

What battery lasts forever? Pixel without sim card? Or other phone using pixel sim card?

Makes sense. As 18T said -- mobile radios are one of the biggest drains on battery.
 
Noticed that after the most recent update, battery performance is not as stellar. Still lasts me a day, but just so.
 
As of now, in Android after 2.3.1, I have no idea what's happening and what to turn on or shut down.

Phones eat battery like no tomorrow.
