My wonderful Note isn't going into Deep Sleep mode which is sure to be one of the big battery drain issues i face. Can someone tell me how to get it to go into Deep Sleep mode?

One issue with the Note and batterydrain is that it dont turn off the WiFi when the phone is asleep. But you can fix this by go to setting for WiFi and set it to turn off WiFi when the screen is off.
When I did this my Note went from using 50% of the battery overnight, and to about 2%
At the same time I turned off the autoupdate feature for Weather, Googlemail and so on..
look at the apps that uses battery if you see samsung push service the it is your problem. i solved this issue by freezing it via titanium backup

Hi
Im running rooted note with darky rom 3.3 and franco's test kernal with no probs up to about two days ago. Now for no reason I can see battery life has dropped drastically and some of my installed apps either do not open at all or some open then just fc. I haven"t installed any new apps in past several days. Checking batt stats it tells me the note is nearly constantly awake with with wifi awake aswell but shows no app or process including wakelocks running that can account for this. Has anyone have any idea what could be causing this and hopefuly a fix.
Thanks
Ingott

BetterBatteryStats or Badass Battery Monitor will help you pinpoint the app/process causing wakelocks and thus preventing your Note from going to sleep.
Have checked with betterbattstats and no app is running causing this problem. I have wifi set to on only when screen is on but wifi is constantly awake this is causlng batt drain I believe. Also my installed apps no longer work they fc and some dont even start. Since my last post I have reinstalled darky rom and franco kernal but still getting the same problems.

I have the same wifi problem !
I have rocket rom V23 and abyss kernel 4.2
BBS shows no wake lock and kernel wake lock but when the wifi is connected the phone wont go to sleep and its awake and drain battery !
if I turn off the wifi it will sleep and battery drain will decrease to 0.4-0.5 % per hour.
my wifi policy is set to sleep when screen is off but when i turn off screen the wifi is still awake and i can see it connected in my router lan page and also I can ping it too.
any one has any idea ?
I have found the 'sleep while screen is off' to be very poor. I now use Llama to turn the WiFi off 1 minute after the screen turns off (in case I forget something and go back), and turn it on when the screen comes on, but only if I am at the Home or Work locations. It now works exactly as I want.

thanks for your suggestion.
I just found Batteryfu very useful for NOW !!!
it has good options for wifi and mobile data, also has options for night mode, screen on, screen lock/unlock, while charging ,...
will test it for a day or 2 and will post my observations .
Thanks for all the replies..
I have found what works for me. I wiped kernal using jBroid then installed a different kernal to what I had installed rebooted a couple of times. I then wiped again using jBroid then re-installed my originall kernal again. This solved my problems. Suspect kernal got corrupted somehow then the wipe and overwrite sorted it out. Thanks to darky rom dev robbie hood for the heads up on this.

And my problem went away just by restarting my note.

I have encountered a problem and need some help pls...
I recently flashed to 4.0.3 official rom German version (not leaked version), unrooted. I downloaded the firmware from samsung-updates.com, upgraded the phone, everything worked fine.
However, i found out recently that sometime if i left phone idle, the battery drains really quickly. say if i charged it up to 100% and left it over night, next morning, it will only have 60% left.
firstly, i went to Settings, then Battery, i found out even when the screen is OFF, the is still keep on "awake" -ing, i then downloaded CPU spy, i can see that when the battery drains quickly, CPU was constantly operating in 200MHz, something must be running in the background all the time.
I also downloaded betterbatterystatus, i have checked the wakelocks, everything worked fine.
I wonder if any of you guys have the same problem.
This does not happen often, and i believe restart the phone can "cure" it temporarily, but it will come back you dont know when...
btw, i have turned off google+ services.
please help and excuse my English.
Thanks

You have Wifi on? Or added a new app recently? I usually reboot my phone when I install a new app since last time I installed a new app there was battery drain issue.
This helped making my phone deep sleep and decreasing battery drain
0.go to settings > sound and turn off touch sounds and screen lock sounds
These steps stop the kernel wakelock 100% problem:
1.turn on aeroplane mode
2.turn off device
3.take out battery for 10 seconds
4.turn on device
5.wait for everything to load
6.turn off aeroplane mode
Take a look at this blog article

I had the same issue and solved it by doing the following steps:
1. Allow a charge to 100% to occur
2. Before you unplug the charger, unlock your phone to the homescreen
3. Restart your phone
After doing this, I noticed my phone goes into deep sleep and my battery lasts longer throughout a day.

Mine did that, but I did the charge up, airplane mode, shutdown trick and it
fixed it.
Got a friend on an older galaxy captive, he finally got around to upgrading to GB,
and his was rooted before the update and he forgot to unroot before the update.
After the update, part of the old root program was running all the time sucking his battery down. After he figured out a way to get rid of it, the problem with battery drain stopped.
If the charge, airplane, shutdown trick doesn't work, download something like CPU Spy and see what's taking up the battery. Could be something left over from GB still running.

I was having a heating problem when charging the device (Battery temperature above 46C) and huge battery drain.
This was fixed after following the above steps.
Hello world,
I just noticed this disturbing issue. I lost about 16% battery in one night. When I looked at battery state I noticed alot of tiny little wake moments during the night.
What kind of application can cause this? Or are there any known bugged apps that cause this?
Wakker is dutch for Wake

. THE Galaxy Notes when goes into standby (screen off) should go into deep sleep mode is a mode that allows you to keep to a minimum processor frequency to conserve the battery. Unfortunately, between the various firmware updates that we do and the various programs that we install (some of these work in backround without noticing it) can happen that the Note is no longer able to enter deep sleep mode remains fixed at 200mhz even while on table with display off.
To find out if our notes go into deep sleep, just install the free CPU Spy download here: https://play.google.com/store/apps/...wsMSwyLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ..--- If your notes do not enter into deep sleep the greater the percentage occupied by the item above, or 200mhz. The fact that it is a 200mhz is quite useless to us since we're not doing anything with the device as it should be on standby at that time. It happens so that at night, leaving the device on but without the latter is used, however, so battery consumption (having remained fixed at 200mhz) and the following morning surprise that we find the percentage of low power.
To overcome this problem needs to be done in the following way: Deep Sleep Guide
- Go into settings and remove the following tones: sound freezes the screen and sound selection - Set the device in flight mode - Turn off the device - Remove the battery for 10 seconds - Power on the device - Wait until everything is loaded - Remove Airplane mode
And that's it. The Notes should regularly go into deep sleep after doing this guide. To check everything just to keep notes on standby for about ten minutes and see if The candidates and the percentage of deep sleep increases.
Hi
Even I face this battery issue....it is severe in my case. I hardly get 14 HRS of battery life even after about 30 charging cycles
I've installed CPU spy, I found that the CPU stays in 200Mhz, for testing purpose I had kept my cell phone untouched in flight mode for about 12hrs but still I lost more 50% of battery.
I had tested the battery by completely charging it, it just drains before my eyes . . .
I don't know if this is deep sleep issue. please help me.

1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others. 2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html 3. Set Brightness to low value, disable autobrightness 4. Disable or scale down vibration and haptic feedback 5. Automatic syncing of your accounts is battery consuming. Sync manually if you can 6. Set screen timeout to 15 seconds 7. Disable fast dormancy (dial *#9900# and do it from there) 8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state 9. Disable location services via wireless networks - are you travelling that fast that you need those? 10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.
Download BetterBatteryStats and look for wakelocks (partial and kernel). Google them if you don't know what they do. Then uninstall them or fix them somehow.

Am happy to say that the deep sleep issue haS been resolved.
I downloaded better battery stats, found that the process l2_hsic was stopping my phone from going to deep sleep mode. I tweaked the wifi settings and the battery life increased exponentially.
Thanks better battery stats

What do you mean "tweaked the wifi settings"?

My galaxy note 2 battery is draining fast and the "android os" is at about 65% at end of day and now my battery last about 10 hours. I was trying to follow your instructions above but got lost trying to find the settings to remove some tones you mentioned. Which tones are you speaking of.
Thanks...

Note 2? Wrong forum..However, to answer your question, he is talking about the tones under Settings> Sound> System.
Hi,
I changed the setting to turn off Wi-Fi when the tablet is in sleep mode. However, when I check my battery usage, it indicates that Wi-Fi is on almost 100% of the time.
Can I do anything to fix this?
Try better battery stats available here at XDA. Although it's designed to help you find out what's using your battery, the info the app produces will show you what programs are running the most. Odds are one of those uses wifi and that's what's keeping it on during sleep. Just remember that you'll need to be on battery and not plugged in or docked to gather the app usage info.

Definitely an app keeping wi-fi awake. I have mine set to never turn off during sleep and I only lose 3-4% overnight. Wakelock Detector is another app that can identify which apps are keeping wi-fi active.
Thanks, I'll try to see if these apps can diagnose the problem.
Hi All,
Facing a problem with my Galaxy Note on 4.1.2 (rooted). Phone shuts down in night, most probably when android tries to go deep sleep. Actually by checking the apps log like system panel / Battery monitor widget, it looks like android struggles to go deep sleep and shuts down. I tried to reformat the SD card (32GB class 10) to over come this issue. But no avail. Still facing this issue. In day time it goes to deep sleep rarely.
Please help.
Regards,
Karthi
It could be wakelock apps.. download wakelock detector from google play and deactivate any app causing wakelock
Who do you mean? Phone goes automatically off in the night? Due to battery discharge or sleep of death?

Tried wakelock app also. No abnormal activity.

Automatically shuts down at night. Not due to low battery ( but considerable amount of drain will be there).
Thanks.
Try a clean install of JB ROM and retest. If still the same there could be some motherboard issues.

Issue solved!
Hi All,
Thanks for the suggestion/help. It seems like the issue is with MicroSD (even though it is just 3 months old). So bought a branded one and replaced it with that. Now no more sleep of death or frequent shutdown.
Thanks.:victory::good:
