Hi guys, are someone experiencing the same trouble with battery life since ? When i go to sleep with something like 12/13% life, i wake up and the phone is off, Before update, i wasn't losing any percent of battery.

Am i the only one ? Thanks

EDIT : Still have this problem .. Didn't found the reason but this trouble seems to be more significant in sleep mode, to be honest, when i'm using the phone, the battery consumption doesn't surprise me. I'm using Jolla 1, but the problem seems to affect all devices on

Is there a way to set the min and max cpu freq on Jolla 1 ? I remember on n900, with a higher max cpu freq, and a lower min cpu freq, you was able to win performance & battery life.

EDIT 29/09/16 : I saw a lot of people talking about flight mode, and in the "lost" changelog of 2.0.4 i remember i saw "Issue of battery draining in flight mode fixed" I want to precise that i never uses the flight mode.

actually it feels like the battery life of my Jolla 1 improved since the update, but I didn't take any measurements

nothing negative so far

Had the same problem last night. However during the day I don't feel like my battery life is worse. EDIT: Tonight i put my phone on airplane mode, only dropped 2% overnight.

Battery life is good for me, no special issue with latest update. Maybe even a little bit better, but that's only a vague feeling.

Good battery life here, few calls, two email accouns syncing, internet browsing, some other usage and 1,5 hours video playback, I'm going to bed having battery at 67%.

Has anyone tested the early access release? Does the huge battery drain appear in this version as well?

Negative, it's been fixed. I've tried that this night and my AquaFish lost just about 2% or battery life in flight mode :P

tom.i ( 2016-10-06 11:33:28 +0300 )edit

Good to hear. What are your experiences when not using flight mode? Cause more of us have reported that the battery drains appears even without switching to flight mode.

aleeex87 ( 2016-10-06 11:57:54 +0300 )edit

My AquaFish lost 5% this night, with data disabled but not in flightmode. A lot better than before.

Great news!!! I can now move from and jump pass 2.0.2.x Thanks Jolla, waiting for the release to all users

i am on jolla 1 and before updating to aurajoki my phone lasted at least two days given my pattern of usage. over night it lost two percent at most. now my jolla lasts one day and battery loses nine percent every night (wlan and mobile data off, but not in light mode). with e-mail sync customized, the loss is even 11-12 percent.

suggestion, you go back to the last version, got battery drain bugs !

choo ( 2016-10-01 16:56:13 +0300 )edit

It has been establish that 2.0.2.X has a serious battery drain issue, and nothing seems to work. Till the next update arrives hopefully with a fix to this your options are either to get used to it or to downgrade. I settled for the later since spare batteries aren't forth coming. More complaints about this won't change much am afraid

I had the same troubles with battery drain after the update (max. ~2 days). I also only use 3G for calling and SMS, mobile data or WIFI just on demand.

Last week I played around with another SIM (so I completely switched off the phone (and removed the battery)). After that it looks as the battery life is as usual before updating (~5-6 days).

Jolla 1,

Have switched off for hours as well as removing all components (battery, sim card, sdcard...) nothing worked, downgrade was the only remedy... Am happy it worked for you... Think I'll wait on the next update

The battery drain is annoying as I'm doing everything to save energy (2G, no WLAN active, no mobile Internet) and yet it goes down rapidly during the day. Before the update to the latest version this was not happening.

Try to reboot after flightmode... it helps me a lot :)

As a followup to my own question-answer (but this should be more visible) and that I noticed that in my case it's also messageserver5 that goes crazy - I've installed Battery Log and fully charged the phone on 19.09.2016 20:11. Since then living in a Stone Age without wifi or mobile data ;-))) (except that using my phone as a phone as usual) and I still have 36% of battery and Battery Log tells me that it could last for another 18h and 41 minutes. That's what I would call my normal Jolla (1) usage (sincerely speaking, before 2.0.2.x "going crazy", with my wifi/mobile data usage it was more like 1 full charge in two/two-and-half days).

So for me it looks like 2.0.2.x has (at least for me) broken messageserver5. Without it running the battery drain seems normal. So, disable your mobile data and wifi and feel free from the electronic information chain again! :D

I noticed (using top) that by having two applications (Viber & Telegram) active CPU usage increases to 1.0 and the CPU load of the system is more than 60%, and kswapd made continual use of the CPU. If I stop these two applications and refresh Dalvik, the CPU load drops to 0.01, and kswapd disappears.

Can confirm. Yesterday morning I've had 70%, almost no activity (like 2 SMS, 15 minutes of surfing the web, a short phonecall or two) and today morning it had 4%. Today after 4 hours of usage (some web, some e-mail - but not a lot - and about 40 minutes calls) I'm almost at 60%. At the end of the day it will be dead. On previous build I had to charge it once per 2-3 days of usage. No it looks like I will have to charge it every 12h.

IMHO this should be fixed ASAP.

PS That's my first bigger problem with Jolla in almost two years. Great job btw. I love this phone. :)

I can confirm the unacceptable bug in this, but I thinka fix would come with a feature update which could be a while. I in the mean time had to downgrade , after which I can say with all boldness that the battery drain is nonexistent on Will gladly remain there till this is fixed. Need I remind anybody that jolla's spare batteries aren't available ?

DameCENO ( 2016-09-19 16:42:50 +0300 )edit

Update: 39 minutes of uptime (33% battery) and I noticed in top that messageserver5 eats CPU like crazy. Opened apps: sms, phone. Almost no activity from reboot til now.

And Jolla got a bit hot. How to downgrade? :) ::edit I can see there a topic about messageserver5 going crazy

Piotr ( 2016-09-19 17:09:23 +0300 )edit

To safely downgrade as I did since there were reports of bootloop: First to all apply all patches

Then if you updated powermenu2 uninstall it as it is dependent on 2.0.2

Then run these commands in your terminal app

ssu release

version --dup



With it am back to and free from this silly bug

How does your "CPU sleep, %" graph look like? For me, it is mostly zero which I presume means CPU is not at all sleeping. Even when the phone is not in use, the graph is zero. Not sure if I am reading it wrong.

Well I am sad to say nothing seems to help with this weird battery drain since this update, on standby on overnight I had an impressive 2 % battery drop overnight, yesterday night it dropped from 50% to 38% this morning. Even the little routine that seems to help after each update when I notice battery drain (running as root systemctl stop tohd.service and systemctl mask tohd.service) has zero effect on this alarming battery drain. Since spare batteries aren't forthcoming, this bug is simple unacceptable. I think it is ssu re to downgrade right? Until this is fixed, any addition or improvement in this SFOS release is not worth this insane battery drain

try disabling any xmpp accounts, such as facebookchat. another problem on my jolla is that sometimes msyncd prevents the cpu from entering sleep state. killing msyncd helps in such situations. it restarts automatically after killing it, so no problem with email sync should occur.
