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

@DameCENO: I'm talking about 2.0.4

I understood my misconception after installation good tool SystemDataScope. It's indicated on screen battery energy in Wh, not battery capacity in Ah. It's very low consumption(in mA) in Standby mode for me. (v.

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.

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.

I honestly dont know whether what I am doing is helping me last longer (in terms of battery) or it is something else, but you can try the same, maybe it would work.

not using any themes/ icon packs/ fonts not using any homescreen/ lockscreen patches (e.g., pulldown covers, no home carousel, etc.) using a device lock (dont know why but this made my battery last longer) not using animated ambiences using automatic brightness not using sensor based gestures turning google to offline in presence turning automatic time update off using force powersave mode on stopping androiddalvik when not needed not keeping many accounts synced

And that's all. Really a lot but most are one-time tweaks. Hope you get a better battery life after this.

Bad situation, indeed. I am sick turning off my Jolla C in the evening and turning on in the morning, again. Could that 'force powersafe' be integrated with e.g. Situations app to put off and put on , respectively? Yes, it's true that I do not need any syncing while sleeping. I quess some commands are needed, but what they are? Not even just 2 G mode helps anything but - 12 to 16 % usage over night.

N9Sailfish ( 2016-09-08 14:14:39 +0300 )edit

no but you can set a preferred batttery percentage threshold instead of forcing powersave on at all times if you want that. I have switched cpu max to 1.27GhZ and min to 200MhZ and put governor to interactive. Battery drain completely gone now. I literally thought at first that my battery percentage is stuck its draining so slowly. using the same things as I stated still alongside cpufreq tweaks now.

Satvik Chaudhary ( 2016-09-08 15:57:53 +0300 )edit

I think my battery life improved after full rebalancing of the file system. Not sure if it should.

mj ( 2016-09-14 23:27:24 +0300 )edit

Ok so been a few days sin e I posted that. I will tell you what I am currently doing. cpu configs as stated earlier. brightness now almost all day at ~50%. 8 accounts synced. phone switch off at 2:00-3:00am in the night. power on at 6:00am in the morning. auto-ambience and situations both set. sailorgram synced. android dalvik rarely on (1-2 times a day for 5 minutes at most), heavy usage on screen on time, 29 patches installed. sneak peek on. wifi on for 2-3 hours daily. mobile data 24x7 on. weather and calendar sync on. powersave on 24x7.

BATTERY OUTPUT: 30-35hrs. usage on a full charge.

Satvik Chaudhary ( 2016-09-14 23:52:15 +0300 )edit

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 :)

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

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
