I'm suffering from battery drain and can't figure out what causes it. Drain is constantly about 7-8%/h no matter what I do.
CM v20151012.
BBS and GSam don't really give (me) a clue on what to look at. Android Battery Stats are totally bull cause the percentages don't add up at all...
The battery diagram doesn't really show a degradation. There are no sudden drops at all.
Any idea on what could cause this? Thank you.
Screenshots attached.
Log attached.
no bt issues at optimized cm13 guys.No devs are working on this ROM right now. AFAIK. Sorry guys!
So you guys posting issues are unlikely to get fixed. I'd be happy to be proven wrong and a new nightly is released but I believe most of the s4 cm12.1 devs are now working on CM13.
There are few solutions to these issues, downgrade to CM11, downgrade to stock or modded Samsung, downgrade to a previous nightly which works mostly but has battery drain and BT issues, upgrade to CM13 and live with similar BT,RR, battery life issues to the last official CM12.1 nightly. Unfortunately all the official CM12.1 previous nightlies are not available on the cm site anymore so downgrading isn't really possible unless someone has saved the install zip. I didn't like this idea anyway, and don't consider CM13 stable yet so I won't try it again for a while.
Personally I've switched to Optimized CM12.1 by JDCTeam, fixed my BT issues (99%) and problems with calls on the last official nightly. Battery life is OK for standby but does probably drain a bit more under use than stock (but ROM is fast!) The only major issue apart from strong battery use is my haptic feedback is not working (lol) no vibrate. Rom is version 20160225, there is a 20160226 version but I have not tried it yet.
Optimized CM12.1 is also EOL (End of life) like official so yeah! I'm waiting for Optimized CM13 atm...
There were a couple nightlies during August and October which work better than the last nightly (20151226), the newest one (with least issues) is probably 20151223 from my experience .. I don't have any of these versions from August to October. Most of them had battery drain though.
I also get my Galaxy S7 edge soon so I probably won't visit this sub forum much anymore! Best of luck to you all!
So hyped for CM13 Optimized right now. Cannot wait!!no bt issues at optimized cm13 guys.
tomorrow check the threads at xda
google translate says that ''i feel so hyped'' means "i feel like that new thing will suck" actually
Seems like Google is wrong because it doesn't seem to know what hype meansgoogle translate says that ''i feel so hyped'' means "i feel like that new thing will suck" actually
why do u ask something like that...we got to see random reboot to jdc roms ,long time ago ( maybe 4-5 months)Seems like Google is wrong because it doesn't seem to know what hype means
I assume no random reboots on Optimized CM13?
Never mind maybe it was just me who got rr's on cm13 nightlieswhy do u ask something like that...we got to see random reboot to jdc roms ,long time ago ( maybe 4-5 months)

Refreshing the forum like a mad man waiting for optimized cm 13 to appear
I'm using the lastest CM 12.1 release (20151117). So far so good.
Not sure if 20-30% drain per hour with wifi constantly on when downloading apps is a good thing or not, but I'll report if there are any bugs with the ROM
I'm using the same build & I don't find the same sort of battery drain, even during prolonged heavy wifi use - I only occasionally check my battery stats, I don't consciously log them or anything, so my experience is really only anecdotal - but I don't get anything like that sort of drain - ouch!
After a few hours of using CM 12.1 20151117, I'm quite disappointed though. Battery drain 10% for 20 minutes browsing with UC browser.
And I did everything I could to save power (black theme, black wall paper, underclock...) but still. Downgrade to CM 11 to see if the problem is from my phone or CM
It doesn´t sound good
Pls tell us about your experience and comparison between those roms

you guys need to realize that the handfull of people contributing for jf have moved on from jf. we get no benefit from this. lots of complaining not lots of logs
Be assured that your work and join in discussion is appreciated not only by jf owners.

jactivelte and other Qcomm devices profit when competent people do real coding in Gerrit like you do.
When comparing the commits of (not sure if still maintainer?) AntaresOne:
http://review.cyanogenmod.org/#/q/owner:"Mattia+D'Alleva+%3Cantaresone%40antaresone.eu%3E"
with
dcd:
http://review.cyanogenmod.org/#/q/owner:"dcd+%3Cdcd1182%40gmail.com%3E"
the difference in numbers of merged commits is jaw-dropping [emoji6]
Agree with you that output of logcat is more helpful than words like "X or Y not working".
Please do stay.
ThumbsUp button under every post is free to use in case you're in the mood to show appreciation.
Or started own projects based on CM like "Optimized CyanogenMod 12.1 builds". I still dont get it. Why do we need a optimized Build. Why can't people just contribute those "optimizations" and fixes to the normal CM repo, so that everyone can profit.
