[Q] Deep sleep?

Hi i am just curious my battery only lasts a day, I installed cpu spy and I noticed that deep sleep is not being used. Is that normal or is that the reason why my battery drains so fast? I have read somewhere that even stock uses deep sleep I am not sure so please help. How do you get deep sleep to work?
I am using chobits digitalis v2reloaded and merruk kernel 2.0
sorry if this is a repost or something but i tried using the search box but no guides available only mentions of deep sleep that we newbies don't know about. Thanks

To get deep sleep working flash a custom kernel like savies or kuros or flash a custom rom that already has a custom kernel
For best battery life try kuros kernel it is really good for battery and has good performance too

im using merruk kernel 2.0 and i've read that it works but I don't know why mine does not. Do i have to do anything specific to make it work?

if you have a2sd installed that is the reason why deep sleep is not activated,
use savie's or kuro's kernel,
if it still does not work,
install "better battery stats"
and check what apps are keeping the CPU awake

I've been using Kuros kernel for the past couple of days.
I last restarted my phone 24 hours ago and its spent 11.5 hours in deep sleep

first i'll try fixing the deep sleep issue first. I dont want to adjust to another new ROM im too stubborn lol.
in my understanding deep sleep is a state that activates when your phone's screen is off which should conserve battery. Try googling it for more info.

you are correct,
get a kernel that supports deep sleep,
kuro's or savie's would be appropriate

so merruk kernel does not support deep sleep? or is it just because of my "alarms" which is "android" and "com.gau.go.launcherex"? if its the alarms how do i fix it? thanks

i use merruk 2.0 pre final.. deep sleep is working.. btw im on stock rom.. and its perfect it last my 2 to 3 days just normal uses..

can you install better battery stats and see your "alarms" so that i could comapre it with mine? thanks

Try switching off background data activity in setting.. it might be culprit if you have too many syncs going on.. also disable notifications in all apps.. like hourly checks etc . Then see.. it might or might not help.. just a suggestion.

Install terminal emulator or any terminal from play store..
Type this command in it..
logcat -v long *:W*:S > /sdcard/filename.txt
You will find a file in SD card.. try that.. after running the command. Press power button to screen off.. then keep it for few minutes.. then screen on and end the command to get the file..

have you been fully charging and fully discharging your phone?

What app did you install? Did you install a new rom? what rom are you on? My guess would be a rouge app. Have a look in the battery usage graph or get spareparts and look at the things that are keeping the phone awake.

I would suggest you download CPU Spy to see if an application is preventing your phone from entering deep sleep mode, for example. You may have a lot of widgets refreshing way too often, as well.

The only widget that refreshs at my home screen is SetCPU, in order to monitor the Temperature, but i will try that app in order to check whats going on thanks.

Ok finally I've managed to see what was the problem that was causing such battery drain/loss... The problem is that i wasnt full charging/discharging, now the battery seems to be working fine. Also I've check cpuspy and nothing is interferindo with the deep sleep.. Thanks for the help

Never fully discharge Li-ion batteries.

But is not fully discharging, under %15 damages battery? And also i put from batter over %95 because after %100, it waits until it drops and again charges if i forget there.

Xxls8 battery backup!

New official jb is giving horrible battery backup..
Post your screenshot please...
update:continuous usage time:3.5 hours.

Dude your phone was awake all the time also your mobile network is really bad its better you flash some other modem !

Even if the phone was awake the whole time atleast it should give min 4 hours of backup which we currently get from ics.

Try turning of Google Now and "report my location" in Google Maps. Most sources of battery drain on LSJ consisted of Google Maps automatically checking you into places.

For this we were waiting for such a long time...

I don't get it what the use of this rom when we can't switch on Google now motions etc.. Means battery will blow away in few hours....

I've everything on, flashing a couple of things in recovery, 86% to 26% , tottal backup 11h with screentime 2h5m. Pretty okay, considering the stuff going on in stock kernel.

I have changed modem to xxlph seem mobile network improved allot. Thanks for your advice.

I dunno for myself i've always have problems with deep sleep on Samsung stock roms.

deep sleep is working fine here...without deep sleep i think no one can even think of using this rom..

Official JB is good at sleeping very bad while the screen is on, compare to jelly bam.

My Razr M softbank never deep sleeps

As I am running a stock xt905 rom with xt902 radio on my xt902 and I have many times flashed a new rom and many times reset the fone via recovery
Betterbattery stats show kernal wakelock of suspend_backoff
I searched it and did the settings in chrome but still no help.
The processor keeps running at 384mhz as indicated by cpu spy even when the screen is off
And I have also tried stick Verizon xt907 rom and it still shows the same battery drain!

To my knowledge, the processor in these phones can only go as low as 384 MHz. With certain governors it will turn off one of the cores but that's about it. How much battery life do you get before a recharge?

Wow that's strange... I'm afraid I wouldn't know. Check your battery stats and see if the phone is awake while the screen is off. Also, try changing governors to something like msm-dvsc. That should put your phone into deep sleep properly.

Obviously, a wake lock.
Check the battery stats.
For more in depth data, install the app betterbatterystats.
