Just figured id share what i just found. Ok im on rocket rom v3 with latest speedmod kernel. Well this rom and kernel are great especially battery life perfect deep sleep except for when connected to wifi I would get this stupid l2_hsic wakelock. If i disconnect wifi my note goes back to deep sleep when locked. If i reconnect to wifi back comes this stupid wakelock and ni more deep sleep! This was driving me crazy to the point of changing roms, kernels, factory reset, and whatever else I did! Well i obviously knew it had something to do with wifi so 1 by 1 i started deleting all my apps that i thought had to do with wifi and finally figured what was causing this! It was the app droid sheep! As soon as i deleted this app bammm.... No more l2_hsic wakelock. Anyways just thought this might help some of you out there running this app!

Never used droid sheep in my life but still get this wakelock, so you its not sorted unfortunately. Never even heard of this app.
I know but my point is the wakelock could be app related. It just so happens that droid sheep was the app causing it for me, byt maybe a different app for you!

Thank you, the landlord and I have the same problem has been resolved.
Wait a week before declaring it fixed. the big l2_hsic wakelock thread in questions doesn't seem to think there is a definitive solution just yet.

Odd, mine seems to be a lot better battery wise since 4.3... You might want to use BetterBatteryStats to pinpoint the cause (maybe some wakelocks etc.)
Flash a custom kernel.
Yes, me too, battery seems worse than in 4.2.2. Or is it just because that I use it more now i.e. to restore apps etc?
Really? Oh no!!
I'm still waiting on my ota update

Im gonna go back to 4.1.2 because it has the best battery life which 4.2.2 and 4.3 doesnt have
me too. Really hoped android 4.3 fixed this problem ;(
been having this battery drain problem ever since 4.2.2
Do you guys have this drain problem in IDLE mode? because I do..
rough estimate, it drains like 7 to 8% in one hour when my device is in SLEEP mode..
But to all this, what apps or services seems to be draining the battery?
Sent from my Nexus 7 using Tapatalk 2
I don't know what your talk in about, I'm getting better battery life than I ever did before. I'm UV by 25 running faux kernel (u21), and clean ROM. I just removed all the gapps I don't use, and don't run anything that needs background syncing. Did you guys do clean installs(full flash via fastboot)?
I also turned off daydream which I am suspicious of, yet I have no proof that it does anything

Thats the problem, I hard factory resetted several times and leave it alone with no new apps
installed before.. disabled NFC, my mobile connection.. and still it drains like a leaky hose in idle mode..
some friendly ppl here suggested installing greenify and betterbatterystats and stuff..
but it doesnt really help me pinpoint whats doing the draining.. maybe because I am not sure what I am looking at..
end result, i even flashed (nearly bricked my nexus on several occasions too) and still the drain is there..
I thought my battery is dying or something.. but my nexus is barely 6 months old.. and battery status shows it as GOOD..
so yea, I am stumped..
Yeap.
I am having the same problem with the battery, the battery is spent very quickly, I have less applications installed and lately I have not used the phone to see if it was me and nothing. It may be because manually install the OTA?
Does the rule of waiting a few days/recharge cycles to get a true sense of the battery not apply to Nexus devices like it does to Samsung devices?

The initial battery drain after flashing can be attributed to apps conducting their first sync and the kernel "settling." This only takes a matter of hours at best. After that, one can get a fairly accurate idea of how their battery is being tasked.

i used to get horrible battery drain until I disabled google now.
I'm also experiencing severe battery drain after taking the 4.3 update on my stock, unrooted Nexus 7. It's been 3 days and no improvement.

I too face same problem, and the App sucking most of the battery is "Kernel (Android OS)", second one is "Launcher", "Phone" and "Android System".
Any suggestions solutions found for this battery issue?
I'm not sure what's happening. My Nexus 7 remains idle most of the time, yet I get pretty bad battery drain and then when I check the battery history I see this. This happens during every battery drain.
Any ideas guys?

Wow, have never seen that on any device! Install Gsam or better battery stats if you are rooted to see what's going on. My best guess, it's a hardware issue.

Woah... Is your tablet trying to go Super Saiyan?....
Also I'm completely stock and have never rooted it and the Android system usage was close to 70% of the battery usage.

Have you already tried reformatting? Kind of a pain, but that's the only thing I can think of.
Try contacting Google or the seller they might give you a replacement.

That happened to me once or twice. These spikes are only visible on the battery graph in settings app. I use an alternative battery monitor app from Google play and it does not show any spikes. Also battery life seems pretty in line with what other people report. I simply ignore them since they do not seem to affect battery life.
Could it be caused by the wireless charging functionality being triggered by other electronic devices in house?
I saw the same problem in the G+ community there, but it's Gelexy Nexus which updated to Android 4.3 recently

Yes, but the screen shot shows 2 days of battery , and he don't use the tablet
If I have a Light use I have battery to 4 Or 5 days...
I advise you to factory reset with the battery charged

I'll try doing a factory reset I suppose and see if that cures this. I'll keep everyone updated.

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???

You just keep referring to that forum without actually answering my question, even on that forum
So I was just trying to check how good is my battery life with juice defender. And I found out this Wake lock, this is showing that my phone have never been sleeping, does anyone knows if this part from the juice defender or an android system Wake lock?

I think that's the radio, and it might just be there because it has to be. Might also be other apps causing the radio to be active constantly, though.
Although I don't actually know anything about this (besides that RIL stands for Radio Interface Layer), so I'm probably wrong.
I'm having the same issue, and still can't figure out what's causing it. If you figured it out please report back.

I just moved to HD rom and my battery life have been awesome, so i havent check my battery stats but I willcheck them to see if it was juice defender or just google. :highfive:
So it looks like it was Google analytics the reason why the phone stay awake when is connected to wifi

Thats really weird, have you modified the kernel at all? you should try to reinstall the rom fresh.
Nothing modified or tweaking at all, Just complete stock kernel coming from Hyperdrive ROM and I still getting excellent battery life. Weird

Ok i keep it straight..
Its my first Android device (The S4.)
Switching from my nokia c7 i've had this issue of alarm not going off when phone's off..
Actually i faced this problem that day when i had only 4% battery left (obviously it wasnt going to last that night)
So i turned off the phone and thought the ALARM would wake me up the next day..( as my nokia always did )
But to my surprise it didnt...
I did search for some solution on xda but no luck..
But then i saw the link of alarm working WITH PHONE OFF on the Rival HTC ONE..(http://forum.xda-developers.com/showthread.php?t=2406083)
So i was wondering whether the devs would be able to make some app..(Or refer me if theres any as i couldnt find one..)
Thanks for your precious time..
Regards.
Me
EDIT : So i was going though some more stuff on this matter and found something relevent..
Like there is a real time clock running on pc (that keeps time even when its off)..
Maybe HTC does use that to make its ONE power on ..
I think some files in the kernel can be edited for some progress on our s4 ( I am completely a noob and have no idea about kernels n all , i just read it somwhere)..
Maybe some real pro can help us out here, by studying htc one's files.. and try to make it work on some other 'SmartPhones'.
+1 to that plenty of time phone nearly dead and would love to do this if possible

The problem is that some 'smartphones" never really turn off.
My Blackberry Storm was one of those and my guess is that the previous phone you had didn't either.
If the phone is in deep sleep mode, then it can wake up.
If on the other hand, it's off, and I mean really off, there is nothing you can do.
The current crop of Android phones turn off; not go into a deep sleep.
Then how can HTC one do it..
I mean it may go to deep sleep..
But can't our s4 go to deep sleep..?

When your screen is off your phone is in deep sleep. At least should be i dont know how they did it but when you turn off android phone its off. No alarm. Maybe they have modified fly mode and altered frequencies for cpu gpu etc to be just enough to ring alarm with almost zero power consumption. But again its not off. I miss that too. Its like where to **** is my charger or hope my alarm rings
Sent from my GT-I9505 using xda app-developers app
With screen off battery goes down by more than 8-10%
I don't think that's deep sleep.. (in deep sleep battery shouldn't drain more than 2-3%..)
Yup if HTC can do that y cant Samsung.. Or other devs..

It's not a matter of firmware/software (which you clearly don't understand), it's a hardware thing. The hardware isn't capable of it.

You probably didn't read some of the replies on that thread..
It doesn't work on AOSP or other roms but only on SENSE rom..
So it is A MATTER of firmware./software..
So I think it can be achieved..

Check your apps. I have 4% over night data off. Once i broke power button on lg p990 so few days i had to live with no deep sleep to be able to turn screen on with volume buttons and man, drain was over 15%/hour.

Dude only 4%,Thats great for you..
Do you use any battery app.. Or its by default..?
I've removed one phone lock app which did save me about 7% drain but still cant get it below 8%..for ( 8-9 hours of sleep )
But i'd still love this alarm feature..
Just test it and no, it does not work.

Yes. Software-based. The question is that if a 3rd party app have access to the system to create an "auto on" or if is something that needs to be manage on the OS itself. Maybe with root access?
