I've confirmed that the default powersave patch included in xenial is wrong, as it patches libnm-util which is deprecated, as opposed to patching the new libnm0.
I've update the version of NM in the silo for VPN with an updated patch which restores WiFi powersave by default. https://launchpad.net/~ci-train-ppa- service/+archive/ubuntu/landing-077/+packages -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1579915 Title: network-manager 1.2 uses more power Status in Canonical System Image: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: On krillin and arale, power use went up significantly in new builds starting on May 4. So far, I have results for: * krillin rc-proposed 324 and 325 * arale rc-proposed 316 and 317 When the radios are off, results are unchanged. However, power went up in two common cases -- standby with all radios enabled, and screen-on with radios enabled. * krillin standby: ~8mA -> ~80mA * arale standby: ~35mA -> ~79mA * krillin screen-on: ~177mA -> ~215mA * arale screen-on: ~305mA -> ~353mA Quite a few things landed in that build, but some of the top suspects are: * network-manager got updated to 1.2 * indicator-network got a cell data switch * USS got "fixes to sleep/idle settings" * ubuntu-push got a fix related to network-manager * libhybris got partial support for wireless display * account-polld got a new calendar plugin Full list: http://people.canonical.com/~lzemczak/landing-team/ubuntu-touch/rc-proposed/bq-aquaris.en/krillin/324.commitlog http://people.canonical.com/~lzemczak/landing-team/ubuntu-touch/rc-proposed/meizu.en/arale/316.commitlog This change cuts typical standby time anywhere from 50% to 90%, so it probably should be fixed before release. However, tests suggest that simply turning off wifi returns the phone to a nice low standby power -- about 6mA for both devices.
