Deep sleep problem

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...

Mobile Dock Power Saving Mode Not Working

Hi all- Lately I have been getting terrible battery drain when my tablet sleeps while docked. I noticed that even though I have the Asus custom option for Mobiledock power saving mode enabled it does not work. I remember with my T101 I would have to enable, disable, and reenabel but that does not work. If I sleep the tablet and press any key on the dock it wakes. I suspect this is since the last recent update as the problem also seems to have started recently. My tablet is completely stock and not rooted yet.
Anyone else notice this?
Thanks
Moderater- Sorry, I was doing search on this and thought I was still in the question/troubleshooting forum. You might want to move this thread. mm

Wakelock manager is not working properly on my system. When I try to perform any action I just get a message that says "unable to perform requested action at this time, try again later." That said, it did open to the CPU wakelock page that was sorted by duration. The top of the list was Avast Mobile Security with a duration of only 9secs. I'm guessing that does not pose much of a problem.
I previously have BatteryStats Plus installed. It also is no longer working and is constantly crashing but I have been checking it since the battery drain problem started. It has a page for "potentially draining apps" that I am guessing also has to do with wakelocks. It has always reported that there are "no potentially draining apps"
What I also need to do, and should have tried already, is to sleep the tablet without the dock and see how the battery holds up.
I do know that the Asus Custom Setting for Mobiledock Battery Saving Mode is not working. Any key on the dock will still wake the tablet with this enabled. I suspect this is the problem. I should mention that I also have the tablet in Ultra Battery Saving Mode.
Can anyone with the latest update installed tell me if the Mobiledock Battery Saving Mode in setting under the Asus Custom Settings is working for them?
Thanks

Sounds like your device is not sleeping at all so you need to find out why - which wake lock detector or better battery stats would do - so you need to get a logcat of why they are not working
Sounds like you have major issues to me....

Well I know from the reviews that Better Battery Stats has been crashing for a lot of folks. A logcat is a good idea. Maybe it's time to finally root and flash a new rom as well. Thanks

I have no significant drain with tablet sleeping when not docked. This is similiar to early problems with the TF101.
Is anyone else having dock draining issues? Is the dock power saving mode working for anyone?

f-kernel 1.5.1 phone constantly waking up from deep sleep

since i flahsed this kernel, the phone works, but it wakes up from sleep mode all the time, causing the battery to discharge very fast. Is there a solution for this?

Exynos Note 9 screen off battery drain (not entering deep sleep)

Hello!
I've owned a N960F for about 2 months now and recently I'm dealing with extremely high screen off battery drain. Looking at the stats offered by the battery tab in device care I am unable to pinpoint the cause.
Furthermore, accubattery shows very low deep sleep time. Last night it managed to achieve an incredible amount of deep sleep of 0 minutes and drain 12% in just 5h 20 minutes of screen off time.
Screen on time is not a problem, while using the phone the battery usage is normal and I am pleased by it's performance, but it is greatly affected by the screen of consumption.
Does anyone have an idea what might be causing the device to not enter deep sleep mode? Or how to find out what the problem could be that makes it use up so much juice?
Thanks in advance!
Screenshots (the accubattery is from yesterday, while the device care one I screenshot just now):

Difficult to tell, possibility is an app in the background preventing deep sleep.
When you use device care and then select battery, followed by settings you get a further screen of options, you may be aware of this.
I have used these settings, it might help.
An alternative approach is to uninstall an app to see if the phone then goes into deep sleep

i found a wierd bug recently. If you're google account has a sync error, like gmail, contacts, messages, ECT.. it will not enter deep sleep.
go to settings>accounts&backup>accounts> Google account>sync account>
Do you see anything with a circle formed by two arrows? those items can't snyc in the background for some reason. usually because the phone has put the app to sleep, optimized it, or restricted background data access. turns out my contacts arent syncing right now, glad i checked.
use this to try and help troubleshoot if you need help.

this might actually have been it, I found a weird Office account that was not syncing (I don't even remember adding it) and I removed it, I'll update if it has fixed the issue

for me, the problem was that my Contacts app was set to non-optimized ect ect... but the googlecontactsbackup app was set to optimized. I didn't even know that apps could have dependencies that show up as other apps. (i installed google contacts to replace samsung's people app).
i went from 1%-1.5% drain per hour, too .5% drain. significant change for me since im already heavily debloated.. thanks for making me look that deep lol. this is why people prefer iphones i suppose.

Are you debloat with adb and console?
Which apps disabled?
I think that Note 9 exynos have problem with consumming battery in sleep mode.
My N9 always "drain" 3-4 % in night after little debloat but A5 without debloat and with more apps consumming only 1-0% per night.

I use EMUI 9.1's own App Launch panel to prevent apps from running in the background or starting up on their own, I get around 3-4% drain overnight on the P30
Settings > Battery > App Launch > Set the apps to manual and turn off the background / auto start switches for any apps using a lot of battery

20%？！？ definitely not normal. Mine like 3-4%

I leave mine connected to WiFi, it uses way less battery than LTE/4G
Also disabled BT and WiFi location scanning in Location Access > Advanced Settings
Disable any apps you don't use that may be running in the background
And weirdly, my battery life improved best when I set the phone battery settings to "Performance mode" which goes against everything it's meant to do, but that's what happened, worth a try with yours for 24/48 hours to test

Going to give this a try and report back love everything bout this phone but the standby drain is driving me nuts...

!!!!!
I had S10 plus and I went to sleep it was 99% when I woke up it was around 64% sold it 2 day ago and got the P30 pro , today is my 4th day with it and when I wake up it’s always above 90% leaving bluetooth WiFi all running normal so don’t know what’s happening with you....

Went to bed at 100%, woke up and it was at 99% this morning (11 hours on battery)

Try to find the cause in Settings - Battery - Usage and detail of batteryusage. This can sometimes indentify an app causing this.
Sometimes problems are solved by wiping the chache partition. Youtube movie how to wipe cache

Do you have aod (always in disolay) on during the night?
That will drain a few percent also. I personaloy turn off aod between 11pm and 7am.

I was getting quite a bit of drain when I had AOD enabled, so I disabled it and chose to use Double tap to wake instead, however I also debloated through ADB around the same time so could have been a rogue package that I removed..

Double tap to wake will use power keeping the screen's digitizer panel active waiting for your taps
I always disable everything to do with keeping any part of the phone awake during sleep, AOD, gestures, taps etc, and with DND enabled until 9am that will kill any notifications waking it up too
Looking at the battery usage overnight, the phone logs only 3-4 very short wake events, one I know is it checking for firmware updates and could be disabled, others will likely be whatsapp/outlook

Although this is true, it's extremely minimal in my opinion, I go to sleep with my phone on 100% & consistently wake up on 99-98% also I don't have DND on at night so the odd text message or email may come through and wake up the screen

Good to know, yea I managed to get mine down to 1% drain overnight too, as good as their battery management is for that side of things, it has ruined WhatsApp, no matter what I set to exclude it from power saving options I still only get messages when I wake the phone up myself, sometimes only when I actually open WhatsApp, it's gotten so bad now my gf texts me to tell me she's sent me something on WhatsApp, she can even text me while I am using the phone to tell me that and I still never received anything until I open whatsapp
Seems this problem goes back many years with many previous Huawei devices unfortunately which means there is likely never going to be a fix

I removed a lot of Huawei's preinstalled apps to as I don't really use them, I also had the exact same issue with WhatsApp & Twitter, the way I "solved it" strangely enough was disabling them from settings > battery > app launch & restarting my device, then re-enabling them & restarting again, it's been fine ever since could have just been a fluke but it worked so..

Yea I've changed that App Launch setting many times without any luck, I found a post from way back in 2012 I think it was saying there were 3 different settings that needed changing to fix the exact same problem that still happens today, needless to say this will be my last Huawei phone, not difficult to whitelist something as widely used as WhatsApp, I mean normal messages works fine and that's a Google app not a Huawei app so no reason another 3rd party app couldn't do the same if they wanted it to
