Hello, I have Sailfish on my XA2 4113 installed and it worked with the instructions. What strikes me is that the battery discharges faster than my Xperia X. Lost 35% overnight. I use only one card and have everything from out-of-the-way wireless. No apps installed. What could it be or does someone have the same problems?

I had also 40% for this night

Same problem, Sysmon shows high CPU usage during idle times but I didn't find the culprit.

phgerin ( 2018-11-09 15:09:45 +0200 )edit

Can confirm on H3113 45 % to 15 % over night.

The consumption is the same, it is high, not a day I come out with little use. Very unusual. Often high CPU utilization. I hope this will help

I have the same problem on my XA2. Battery has enough power for 25-26 hours, mostly idle with screen turned off. There has to be something wrong with background processes. I'm hoping that this will fix itself in the upcoming days because in theory there should be enough battery for 4-5 days of idling around... At least that's what I would expect.

I can confirm this behavior

image description image description

Battery lost 15% in 4 hours without significant usage. No Sim cards, only one background app and syncing emails every half hour

The same time my xa2 plus running Android lost 10% with usage, with all background services and 2 Sim cards

What app would that be?

System data scope

I cannot find "System data scope" in the store, could you elaborate?

tkteun ( 2018-11-17 16:57:22 +0200 )edit

It is called SystemDataScope and is in OpenRepos.

I suspect that this issue is not specific to Xperia.

On my Jolla 1 I have drastic battery drain too after update to

On the graphs you can see some very regular peaks.

At about 16:00 I plugged the charger in - and CPU load decreased! I plug it out - CPU consumption up.

No apps were running simce about 11:00, just a couple of calls and several SMS messages.

I see the same battery drain on my brand new XA2 H3113, though I don't see the CPU decrease during charging that you recorded (can't upload the SystemDataScope screenshot because I have no Karma).

Basically my XA2 sits unused on my desk all day signed into cellular and WiFi and after 26 hours (tops) it's empty. Same without SIM card. Doesn't matter which apps are open either or whether email checking is turned on for the two accounts I added.

togato ( 2018-11-23 00:56:27 +0200 )edit

I have noticed a few times reduced batterie drain during charging.

phgerin ( 2018-11-23 08:05:03 +0200 )edit

I'm also losing up to 20% battery overnight on my Jolla1 since updating to Sailfish 3. Wifi and BT on (nothing connected to BT), mobile data off. This is 2-3 times the overnight battery drain on Sailfish 2. -- Edit: After a reboot it was OK the next night, but I'll continue to monitor it.

What happens when you put it in flight mode during the night?

If I looked correctly then there is almost no drainige. Maybe some of you can measure (see, track, etc) to confirm this. It may pinpoint the developers to the part that is not as energy efficient as it is under other os-es.

Else maybe this post on Stackoverflow may help or give clues.


I checked it between 5.30 en 19.00 today, so 13,5 hrs on flight mode, only lost 5% :)

This would mean a fully charged device would survive 270hrs (or 11+ days) in flight mode. Hopefully they are able to fix this in the upcoming 3.0.1 release.

Nice background info regarding this topic. Maybe Jolla can call the Helsinki University ;)

Else the team at Jolla may be able to trace the consumption in the Linux environment:

  • Studying the time the processors spend at different performance states (P states) and different power states (C states) as well as interrupt activity can also help identify if an "idle" machine is actually busier than it should be. Tools such as 'idlestat' can be helpful to identify busy states.

More good research info can be found here:

For me it has become clear that WiFi is the culprit. So much that I tend to use LTE/4G mobile data even at home, which is crazy.

Kopekenscheich ( 2018-11-28 08:45:19 +0200 )edit

I have SystemDataScope running, so I can test the flight mode during the following nigh (I usually charge during the night). I'll give an update at some point tomorrow when I have time to upload the statistics.

Edit:@Kopekenscheich, same for me. I don't use WiFi almost at all now. Doesn't really matter, since I have basically unlimited data plan and don't use the phone much in general for heavy data (down)loading. But I've always had the idea that WiFi would be a lot easier on the battery than mobile, but - seems things can go both ways. :)

raketti ( 2018-11-28 08:48:34 +0200 )edit

I can second @Kopekenscheich's findings. WiFi seems to.drain the battery. I have developed the habit to switch if wifi and reboot my phone when I leave home, as I have the impression that switching wifi of doesn't lower battery consumption. only a reboot send to bring it back to normal .

HI! I had almost same question.

If the WLAN on XA2 is active, it looses above 15% per night (~8 hours), if only mobile data is active - it is about 3-4%

Is it ok?

edit flag offensive delete publish link more


It corresponds with my findings, and no, I don't think this is acceptable.

Kopekenscheich ( 2018-12-03 13:46:51 +0200 )edit

That is it. And I hope that in official release it will be ok.

sistux ( 2018-12-03 15:13:32 +0200 )edit

Last night I made the same finding... Must be WLAN. Bur my phone lost only 2% over night

This has happened in past updates for other Sailfish phones as well. Usually settles after one or two days. Possibly some maintenance routines in the background (for example btrfs-balance) after upgrades. Search for "battery drainage" or the like and you will find some topics about that.

If it still persists in two days, you should check for corrupted background processes. Sometimes "contactsd" or other processes go nuts ;)

that used to be true with btrfs.on.jolla1 but on experia ?

what i do: dont leave browser.running, turn off android support overnight, go into airplane mode

pawel ( 2018-11-09 16:42:42 +0200 )edit

I have noticed that some android processes stay active after closing the app (especially Here), this get the phone rather warm as well...

rgrnetalk ( 2018-11-09 17:29:04 +0200 )edit

I have generally noticed Tracker (the software used for media indexing) to activate after upgrades. It is likely due to Tracker itself being updated (and thus possibly indexing better & more things) and various media indexing policies changing (like new media locations to scan or new metadata that is needed to be stored).

MartinK ( 2018-11-09 17:49:52 +0200 )edit

Same for me, my XA2+ looses around 25% of charge level in 9-10h idle on the desk (display off)

jollajo ( 2018-11-17 14:43:55 +0200 )edit

25% of charge level in 9-10h idle, It does not sound so bad for me it is drained after 13 .

Hi Sailors,

I first tried to set another governor with mcetools, but this doesn't seem to work. No error message, but also no measurable change. Plus powersave governor was not allowed as an option.

I used cpufrequtils from NielDK to set the governor to powersave. This was the only way I found to get a significant impovement on battery time.

To use this, use the following command in the terminal as root: cpufreq-set -g powersave

Remark: the setting doesn't survive a reboot.

Doesn't this affect overall system performance, e.g. in terms of speed?

Kopekenscheich ( 2018-12-04 14:36:19 +0200 )edit

Yes, but I'd consider the performance still as good. Probably because I had a Jolla before.

For me it is important, that I do not have to worry whether the power will last for the day. The powersave governor provides this.
