HTC ONE M8 running Kitkat (4.4.4). ALL versions after 9.0.82 (038) have bug - Play service continously keeps device awake (even when no apps running and screen off). There are continuous wakelocks and phone heating up - battery draining drastically. The issue resolved when I downgraded back to 9.0.82 version. I suspect Google deliberately introduced this bug to force people to upgrade.
