Android Pie Has a Battery Life Problem (venturebeat.com)
Emil Protalinski, writing for VentureBeat: After upgrading to Android Pie, most users have either seen a slight improvement in battery life or reported no perceivable difference. But soon after we published our story, some users told us that they are experiencing the opposite: significantly higher battery drain after upgrading to Pie. We've been tracking this issue for the past few months, during which the Pixel 3 and Pixel 3 XL launched with Android Pie out-of-the-box and new device owners reported similar problems. Some Android Pie users simply don't expect their phones to make it through the day.
Users on Reddit, the Pixel forums, and Google's issue tracker have been discussing battery life issues on existing devices after upgrading to Android Pie, and some even on new devices (although there are naturally fewer of those cases). VentureBeat was able to independently confirm the issue on a Pixel 2 XL and a Pixel 3 -- we sent the details to Google. Given that Adaptive Battery is the main feature highlight when it comes to battery improvement in Android Pie, many suspected it could be the culprit. Users have reported, however, that turning it off didn't help the situation much, if at all. We were also able to independently verify that Adaptive Battery is not the cause. Adaptive Battery is only available in Pie, but in our tests battery life only drained faster with the feature off. We did, however, confirm that the problem is unique to Android Pie. Users have reported significant battery drain when their phones are idle, anywhere between 10 percent to 20 percent drained in an hour.

From one of the links:
"Phones sometimes shut down abruptly when Android reports 5 percent battery life left."
Hmm, doesn't it sound awfully a lot like Android users could benefit from the optional Processor Throttling feature also posted on Slashdot today? Maybe having that around as an option is not a bad idea after all.
I wonder if there's anything on Android like a battery capacity check? Maybe it's simpler failing batteries with lower capacity that are seeing lower life under Android Pie for some reason...
