Dear All! After updating both Jolla original and Jolla C into version of 2.02.48 Aurajoki, the following problem has arisen:

When both the phones are set into Flight mode(s) overnight (7 hours), the battery drain of in order of magnitudes of 14 - 16 % over night are resulting. Earlier (with Jolla phone) the percentage of only max. 2 % was attained.

Is the previous resulting from bug or something else? Please, could you help. Have you noticed the equal error functions?

My guess: perhaps you didn't re-enable LPM (low power mode) after upgrade? (http://www.jollausers.com/tag/low-power-mode/)

Trimmed the headline a bit for clarity. Fixed the headline too. ...and added some tags. I hope that's OK.

I have the same problem. Over night, my battery drops 15-25%, in flightmode. @objectifnul lpm doesnt make sense on the jolla ips screen. It will drain the Battery even faster.

I'm also with the same problem.

Good morning All again!

The flight mode works now very well with Jolla-1 : 1-2 % battery drain over 16-17 hours with 2.0.4.14.

What comes to Jolla C with 2.0.4.14 update, the flight mode results to battery drain of 10% over 8.5 hours! Do we have any hope for better anymore? Or do we just have to accept that the battery drain still exists ever with the flight mode all the time? It's a pity, Jolla C is however a nice and powerful phone despite the high power consumption. I have now tested Jolla C with 2.0.4.14 for several days. To my sorrow I have to say that the battery drain has the magnitude of 1 % over one hours even with very minor usage of the phone. Still believing for something better.

N9Sailfish! The battery drain is the thing_into_it_self on Jolla C. The battery discharged 6% till 7 hours last night. I didn't turn off MobileData and Dalvik (FlightMode was off). AIDA64, E-mail & WhatsApp worked backgroundly.

Fix for the issue of excessive power consumption released in 2.0.4.

Thank you very much! I assume that this fix will come after earlier 2.0.4.14. Well and fast done.Let's hope that this flight mode issue flies now into history. :)

With the Jolla C running Sailfish Fiskarsinjoki I got a 5% discharge after 7 hours in flight mode last night. To be honest, I'm still not impressed by this energy saving performance... Maybe there is still something wrong with the Jolla C and the latest Flight Mode implementation. This night I will shut down the alien dalvik android support to see if this is the reason for the high battery drain. However, according to SystemDataScope CPU SleepMode is entered properly in FlightMode running Fiskarsinjoki... but this does not help too much apparently.

Exactly, yes. When Jolla C uses Flight mode + Alien Dalvik support off , the battery drain is 7 - 8 % over seven hours. I wonder why Location / Sijainti light is on even with Flight mode? That's why I don't use location after all. As Sailor-John-Doe says, I also think that there has to be some unwanted activity all the time. Or is there some leak of electric power from battery some how all the time? How it is with the electric insulation? I do not know off these things, but there has to be some reason(s) for the excessive power consumption if CPU doesn't show anyting??

Dear Sailor-John-Doe, Hello again. I forgot to wrote earlier that: I use active period for e-mail from 10 am to 20 pm as twice. Silent period from 20 (8 pm) to 10 am.

If I set silent period as manual syncronising, it is possible to reach 7-8 % with flight mode + Dalvik off 7-8 % per 7-7.5 hours, to be correct.

If I set silent period as twice, the battery drain increasases to 10-15 % per 7-7.5 hours.

So, there has to be some problems with Jolla C sleeping state vs syncronising despite the correction algorithm in 2.0.4.14 ... Hopefully the problem is due to weakness or incomplete action of that algorithm or subprogram come.

SFOS update 2.0.5.6

Battery drain 4 % over 7.5 hours in the flight mode with and without email syncronisation allowed over night. Also Alien Dalvik on, because Dalvik Stop doesn't work anymore with 2.0.5.6. I use Situations app all the time.

Thus Jolla C has power consumption 1 % / core as like Jolla-1 1 %/core (2% per two cores). Well done Jolla! So the reduction from (14-16 % for over three months ago) to 4 % today is as average of 73.3% for the battery drain in the flight mode over night.

Thus there exist a lot of optimisation, yet. I should prefer 0.7 - 0.8 % power consumption / core over 7.5 h if possible. Also the power consumption should be lowered totally over one day period (24h) in the near future. So, there is a lot of work still left. Allthough I do not follow this flight more problem anymore, this question will not be closed but be left open.

Let there be Christmas and New Year etc plus peace in the world.

Happy new and ongoing year of 2017!

The battery drain came back to the order of magnitude between 5 to 8 % over 7-8 hours after updates of some apps. Thus, still continuosly waiting for the correction of this battery drain of Jolla C in both the flight mode and also in an idle state. Jolla C is a good smart phone, so we demand this correction asap.

No any good and new news after updating to 2.1.0.9 of Jolla C. This flight mode problem is continuing as earlier. We need public admit from Jolla if all is due to the device but nothing can be done. This takes only 10 minutes. We know that they are living for their big plans, but it doesn't mean that single customers are being forgotten. This does not give any impression of " Communication <3" ; please see Jolla blog as yesterday.

N9Sailfish ( 2017-02-09 08:39:26 +0200 )edit

Nothing new to report. Problem is remaining. I wonder how long the battery of Jolla C can persist?

N9Sailfish ( 2017-03-25 07:12:01 +0200 )edit

SFOS 2.1.0.11. The battery drain of 5 to 6 % over 8.5 h in the flight mode. Thus getting better, but not good in the practice. Now going to loose my hope. Obviously there does not exist any "wonder" app to force the cores to 200 MHz in the idle state instead of 800 MHz at the moment with or without the flight mode with Snabbdragon 210 circuit. Thus not getting in the idle state is really a terrible bug of Jolla C. How does this could be even possible at all?

SFOS 2.1.1.23. The battery drain is remaining (for ever) in Jolla C. No support for it with Jolla C anymore from Jolla. Thus no use to write of it anymore. Pls read also 'No core control' by Asmir. Stopping now.
