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

TNX for the reactions!
now, a day after my Jolla is more at ease with its battery. have to find out about 'balancing' but it seems fine now.

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

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.

Did you reboot it after the upgrade?
Sthocs ( 2017-09-01 17:47:44 +0200 )editMaybe balancing? There are old questions regarding battery drain after Updates. As far as i remember reason Was balancing and drain stopped after few days
pawel ( 2017-09-01 17:49:45 +0200 )edityes... 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
mips_tux ( 2017-09-01 17:49:52 +0200 )editWhich phone do you use? Jolla Phone? Then it really could be balancing...just wait some days and it should become less "hungry"
PatsJolla ( 2017-09-01 22:57:49 +0200 )editMy Jolla1 is also using more power, but not as much as described above. Enough though to call it a drain
