All of a sudden: battery drain [not relevant]
All mW measures I'll mention are delivered by 'Hunger Meter'.
After upgrade to Ohijärvi (1.0.4.20) it was fantastic! The battery lasted for almost four days while surfing and doing a few phone-calls. But after four weeks, all of a sudden, the battery drained completely whithing 10 hours. Excessive heat around the camera lens. 'Hunger Meter' showed an average consumption of ~3500 mW - and even more, and the current consumption fluctuated between 2500 mW and 3500 mW. After a reboot, the average consumption leveled off at around 600 mW just to raise up to 3500 mW again after an hour, sometimes after two hours.
The main suspect was 'Mitakuuluu' because this problem occured after upgrading Mitakuuluu to v02-4. But it persisted even after upgading to latest release v02-10 and even after removing Mitakuuluu completely, the battery kept draining off it's power soon after rebooting.
How comes?
Have you tried to look for high CPU usage, e.g. with top in terminal (dev mode) or using the app Lighthouse? Edit: Might be a duplicate of https://together.jolla.com/question/37774/jolla-is-overheating-by-itself/
lenggi ( 2014-04-08 20:41:35 +0200 )editI doubt this has anything to do with Mitakuuluu. I use Mitakuuluu v02-10 and I do not recognize this behaviour. Do you run any other applications in your home screen? Have you checked what services are running with Crest? Did you mod your phone, wireless charging for example?
Jozz ( 2014-04-09 00:05:05 +0200 )editRelated or not, but during the few past software releases, I've witnessed a sudden battery drain occasionally (perhaps ~5 times in last three months). It's been always solved by a reboot (which I've ususally done as soon as I've noticed it) As the event is rare, I've not got any clues of processes causing it. At least once it seemed to be triggered by or during charging the phone. I've suspected that it might be Android subsystem or apps because my Xperia phone does exact same thing sometimes.
jsievikorte ( 2014-04-09 10:40:21 +0200 )editOK, 'top' shows me these processes on top: d.process.acore hits the process table with constantly 58% systemd-journal between 24% and 33% system_server quite constantly using 21% e.process.gapps between 15% and 17% alienlogd between 3% and 4% The rest is negligible...
@Jozz: no, it's definitly not Mitakuuluu eating up the power resource...
steff ( 2014-04-09 15:44:46 +0200 )editHas anybody an idea what causes the processes above, especially d.process.acore to use almost 60% of the resources? After a reboot, not one process is using more than 1.6%!
