description |
I'm seeing weird and buggy power behavior on krillin ever since rc-proposed 196 (and thus also in rc 38, the OTA8.5 release candidate). The root cause isn't determined yet, but there's a high probability it's related to the landing for bug 1480877.
This issue only occurs on krillin (not arale), and only when wifi is connected. Arale might be a red herring though, since it never really "sleeps" properly with wifi connected and has always had highly erratic results for this case.
Before: ~9 mA
http://people.canonical.com/~platform-qa/power-results/2015-12-08_03:19:30-krillin-195-power_usage_idle/graph.png
After: ~35 mA
http://people.canonical.com/~platform-qa/power-results/2015-12-08_07:36:16-krillin-196-power_usage_idle/graph.png
Here's the commit log for 196:
http://people.canonical.com/~lzemczak/landing-team/ubuntu-touch/rc-proposed/196.commitlog
Something appears to be waking up the phone and keeping it awake about half the time, causing the power graph to look like a square wave instead of a flat line. I don't see additional forks or crashes in the logs, which suggests a long-running process (like dbus) is responsible. |

This issue only occurs on krillin (not arale), and only when a SIM is installed and enabled.
