With wifi associated to a fairly "busy" AP that produces regular beacon intervals with CTS protection mode enabled and also phone data enabled I'm seeing ~24+ hours on deep sleep idle.
With wifi enabled, I'm seeing ~7.5 wifi related wakeups per minute. I then disabled wifi and these wakeups disappear. So the bottom line is that wifi in deep sleep is the root cause of extraneous wakeups. Now depending on how busy the AP is and the kinds of packets, it may cause more or less wakeups, hence different drain characteristics. I'll recharge the phone and see how the wifi disabled case changes the battery drain rate. Attached is two-page spreadsheet of my drain results and also stats on wakeups from deep sleep caused by wifi related wakeup events. ** Attachment added: "wifi related battery drain stats" https://bugs.launchpad.net/ubuntu/+source/powerd/+bug/1372413/+attachment/4299973/+files/mako-rtm-battery-drain-12hrs.ods -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1372413 Title: Extensive battery drain on RTM To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1372413/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
