FWIW, I see the weird new behavior on every test with wifi enabled, even when the screen is on and the phone is actively doing something. For example, while playing music:
http://people.canonical.com/~platform-qa/power- results/2015-12-08_09:19:36-krillin-196-power_usage_music/graph.png ... versus how it looked before: http://people.canonical.com/~platform-qa/power- results/2015-12-08_04:50:02-krillin-195-power_usage_music/graph.png But in flight mode, both graphs are a flat line barely above zero: http://people.canonical.com/~platform-qa/power- results/2015-12-08_11:07:01-krillin-196-power_usage_flight_mode_on/graph.png So, it's not just while sleeping; it's any time wifi is enabled. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices Status in Canonical System Image: Fix Committed Status in Unity 8: New Status in dbus-cpp package in Ubuntu: In Progress Status in network-manager package in Ubuntu: Incomplete Status in qtbase-opensource-src package in Ubuntu: Fix Committed Status in dbus-cpp package in Ubuntu RTM: Fix Released Status in location-service package in Ubuntu RTM: Fix Released Status in network-manager package in Ubuntu RTM: Incomplete Bug description: Krillin, rc-proposed, r83 DESCRIPTION: I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor Here's a log of what's shown in dbus-monitor: http://pastebin.ubuntu.com/11992322/ I'd guess the problem is in the code that actually catches the signals and acts accordingly. HOW TO REPRODUCE: 1) Move to a place where many wifi hotspots are available 2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor" 3) Use the device while keeping an eye on dbus-monitor output To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1480877/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
