Re: Battery dropped 50% overnight

 

https://bugs.launchpad.net/canonical-devices-system-image/+bug/1471913

This one? It has several Dupes already and a heat of 384.

Please... Where is this being worked on? I am asking so that we as the community can contribute to bringing about a solution to this annoying ongoing issue?

This one? Reported 2015-05-26 and currently sitting in the System Image
backlog queue since it has been put there on 2015-10-09. It has a heat
of 132 as of now.

Cheers, Alexander

/var/log/syslog, there are some similar bug reports you could update

    Last night my bq 5 decided to use up all remaining battery (some
    50%) and die before it could ring my 7 am alarm. That was _really_
    not cool.

    I'm attaching my battery graph. Is there some log I could extract
    from the phone to help with the problem?

Perhaps its time to get to the heart of the apparent CRITICAL power
management issue? Instead there are several bugs that will take months
to get picked up - if at all. (Who wants to touch the hot potatoe?)...

I have observed this phenomenon sporadically overnight in the past and
it now seems to be a (almost) constant state. After the latest OTA the
issue has grown with the addition of taking as long to charge the last 3
percent of the battery as it takes for the 97 percent. So far I have
attributed this to the explanations offered here about aging batteries.
I am no longer convinced it is an issue of aging batteries. Something
within the power management of UT is broken. At least for the vegeta-hd
channel. Another thing I have observed is that the WLAN indicator goes
to the not-connected state after a while, although the phone is
connected to the network. This is also new since the last OTA. Perhaps
the phone is spending all its energy on that? I will try to switch off
W-Lan this night and see what happens.

When going to bed i like to listen to a podcast (PodBird) or sometimes
use a flashlight (U-Torch). I have been attributing the overnight
battery drain to those applications - I have however observed the drain
on several occasions while making sure those applications get swiped
away on the app spread. As far as I understand it should not make a
difference what application was run last, as the OS will suspend
anything to conserve battery when not in use? At least it does for
applications like Oxide - try navigating to some web page and leave the
phone for a while then go back. You are presented with a low res screen
grab of where you where only to be brought back to the start page after
a second or so. Frustrating!

MY REQUEST:
Can we find ONE bug to record this under? I'd be happy to contribute
with logs and tests as much as I can find the time. Since the last
charge my phone only took 18 hours (over night) to get down to 22
percent and most of the time it has been just sitting there supposedly
not doing anything.

Attached: /var/log/syslog; /var/log/repowerd.log; Various beautiful
battery graphs, including the one from tonight :-)
