hi,

after the recent update to SailfishOS 2.1.1 Jämsänjoki my Jolla smartphone (first type) has a serious battery drain. with the previous updates, my Jolla could run several days on one battery load en moderate use.

with 2.1.1 it is below 8% in 17 hours and with no use at all, except one alarm going off. all apps are closed.

is anyone else experiencing this too?

and what works as a solution?

TIA

Did you reboot it after the upgrade?

Maybe balancing? There are old questions regarding battery drain after Updates. As far as i remember reason Was balancing and drain stopped after few days

yes... i install android app Signal. Since this installation the battery is drained by this App :-( For the moment the only way i have found, is to stop the process in Settings. But sometimes, the signal process restarted and the battery is "à nouveau" drained. Do you have this app installed.

I also notice that with 2.1.0 version of sailfish OS too.

Sorry for my poor english

Which phone do you use? Jolla Phone? Then it really could be balancing...just wait some days and it should become less "hungry"

My Jolla1 is also using more power, but not as much as described above. Enough though to call it a drain

If You search for battery and Update You will find se several threads like

https://together.jolla.com/question/84767/update-11-heavy-battery-drain/

So if all is fine now, it was Balance.

If You Do Not Know What balancing means search for btrfs balancer

There is even a nice Tool from schturman in Open repos that can run IT from gui. No terminal knowledge needed

The (indeed) "nice tool" is "BTRFS balance checker 2".

I used the following settings in two system files for power savaing (on JollaC):

echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo 200000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

After each past update, these two files remain unmodified, and the power saving was good.

Most probably the update 2.1.1.26 resets the two files responsible with power saving. Please verify this (I tested on JollaC):

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Probably you will find "interactive" as output.

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Probably you will find "800000" as output.

No, experienced rather the opposite: A slightly lower idle battery drain under SFOS 2.1.1.26 on a Jolla 1 phone with Conversations and K9-Mail (so AlienDalvik is also always up and running).

Supposedly something else is causing your battery to drain more quickly than before.
