Wouldn’t the above be a good idea for a native diagnostics app?
The app would measure a full charge cycle, from charge to charge. It would detect which services that were activated (with time graphs), etc. The sensors would add more information.
When a full cycle has been completed the results would be analysed and improvements suggested to the user (with links to suggested adjustments). Optionally the data could be sent anonymously to jolla for further crowd analysis.
Personally i would love to have a tool that helped me save precious battery time.
I think the best tool is the development team, fixing bugs in Sailfish OS and apps which gets the phone to consume too much power. Any reliable user data will surely help them.
My jolla’s battery dies faster than any device i’ve ever had before.
I must admit that same here, and that’s why this tool is pretty important for both users and developers. Please use a lot, fill in good reports with different settings during time. I’m just starting my first overnigh test with everything silenced except for Exchange via WLAN.
I had Motorola Milestone (500 MHz overclocked @ 1 GHz) which could consume battery faster than the AC charger could charge it :D
I had just the same phone earlier and did clock it to 1,2GHz…the same experience :D
Nice Simo – very useful. :-)
Thanks mr.Tides :) After first night there’s already some relevant information, keep up contributing. I’ve deleted few rows of obviously irrelevant information, but by 5 relevant reports it seems that WLAN and Alien Dalvik (Android support) might have something to do with consumption. More data needed! Please use, link, tweet and share, we need reporters!
I would contribute but I have a fatal hardware issue… The phone is yet sill missing!
=:o) But I’m waiting patiently. And I promise to contribute when it is here!
Everyone who is experiencing battery problems should do this: http://talk.maemo.org/showpost.php?p=1395584&postcount=1531
I’ll do it later today and I’ll report my experiences in a day or two. This trick sure did help with my N900.
Thank you for your advice. I should do that today.
Oh, I see I am not alone with this trouble. I am also disappointed with the battery life. My Nokia N9 worked 2.5 days and Jolla barely keeps only one day. I really need the saving eco-mode, that N9 has (when the battery charging level is lower than 10%-20% and all the services like wlan and synchronisation are deactivated).
i told that dual core suck more energy!!!!!!
and the jolla’s battery have more energy than n9’s battery
i told jolla to use 2500mAh battery above all with a dual core!!!!!
and i told to use Li-PO battery that is better than lithium battery
Actually, dual core should consume less power than single core in normal use, because CPU load increases power consuming exponentially.
Can we see the results also? As i dont have my Jolla yet and cant fill out the form with relevant data, to get to the results?
I would be interested to see them as well.
There will be an article of the final results at reviewjolla.blogspot.com when we have enough test data for reliable calculations. Already now, there’s a preview for reports sent so far.
I have to say that Jollas battery last mach longer than XcoverII in same time. Until now when I don’t anymore use that awefull samsung. It’s battery didn’t last a single day at anytime but now after 2 weeks using of Jolla this battery last lot more than one single day. And I use this much more than samsung before.
I calculate a time of 20 hours in standby (100mAh – 5% battery every hour) only without use phone and without internet connections active (WLAN or mobile)
then if jolla make a battery of 3000 mAh for us, we can have a standby of 30 hours
Hi all, just received my new Jolla – delighted with the phone!
While testing it, I noticed that the proximity sensor is not turning off, even when the device is in standby. Fixing this may improve the power consumption by a small margin. What do you think?
Battery life problem is solved, big thanks for everybody here at JollaTides who contributed to the project, both with the reporting tool and comments. Article of the results coming out in few hours at reviewjolla.blogspot.com
I though I would need at least 300 reports before some reliable results, but it seems that 90 was enough after all. Thanks once again!
Many Thanks, Simo, for your initiative and thourough analysis, and to the contributors of the survey!! The results are impressive, as well as Jolla’s and the community’s reactivity!
Note about the proximity sensor behavior described in my previous post: while filming with a camera without IR filter (e.g. mobile phone, webcam) in a dark room, one can see that the IR LED stays constantly on. The consumption of the LED itself is probably negligible. But I could not tell if the the rest of the sensor circuitry also stays on.
Hi,
i made app that measures battery consumption and draws quite nice graphs. Here it is: https://github.com/radekp/jolla-battery-monitor/releases/tag/v1.0
and here is screenshot: http://www.abclinuxu.cz/data/prilohy/2/5/203652-20140212073812-4809591889565946474.jpg
The app is now submited for harbour, so lets see if it will be accepted.
