Hi guys,
after several days of research on google and in this forum I still couldn't find out what's the issue with my new Galaxy S7 device so I'm posting it here and hope for you to help me out.
I also had the same issue on my Galaxy S6 before but it was way worse because of the smaller battery.
The phone is not even a week old and I have issues with it to go into deep sleep mode since day one. I even installed BBS and Wakelock Detector with granted rights for the battery stats but I wasn't able to find out what causes the problem (it's the exynos model by the way).
The Kernel Wakelock stats in the Wakelock Detector App don't show unusual usage anyway, those who are always on top (also with my Galaxy S6) are the "PowerManagerService.Display", "13960000.decon_f" and "PowerManagerService.WakeLocks" followed by "mmc0_detect" and "bbd_wake_lock" (I will post a photo later, I am currently at work in my break) which hold the phone awake around 20-25% so it isn't always in deep sleep or doze mode.
All the google research said that the decon_f thing is connected to the DOT/SOT which I cannot confirm in my case. I still don't understand what the problem could cause because I didn't even use it for a week. When I set up the phone I did it clean without copying apps or using the backup from my Google account so I don't think that could be a reason for it.
I appreciate your help guys, thanks!
I don't really now much about your problem (sorry for that), but if you're rooted i can really recommend you the app ForceDoze. It activates the Doze Mode right after you turn off your screen and lets you black-/whitelist apps, which are/aren't allowed to make wakelocks. It also gives you the ability to control other doze related settings.
It's not rooted and I don't want to trigger the Knox counter so I think I will stay with the stock configuration. I'm really wondering what could cause it, never had those issues on my Redmi Note 4

ok, im fed up with the shocking battery its terrible i cannot last from morning to bed before charging, things ive done
running cataclys and franco kernel, downclocked to 1.2-1.5ghz, runs same to me i only do daily tasks of texting ect, 2.2 seems to only
take affect on higher needing apps
and also using smart 3g to have on 2g when screens off, what do you guys do?
first things first, make sure your phone is deep sleeping and a app isnt causing the phone not to deep sleep.
use betterbatterystats (search for it) and look under partial wakelock after using the phone for a good hour or two.
if a partial wakelock exists, then google search about that wakelock and debug your phone.
also turn off google location reporting & history.
I thought I'd share this information in case others are experiencing similar problems.
The short version: Does your phone refuse to enter deep sleep, and do you have a Pebble smartwatch? Try uninstalling any new watchfaces you have added, it might resolve the issue.
The long version:
Lately I noticed heavier than usual battery drain on my phone - I'm using a Samsung Galaxy Not 2 with Paranoid Android 4.6 (KitKat). I noticed in the built in battery stats that the phone was awake 100% of the time. After some extensive searching and using BetterBatteryStats I thought I had narrowed down the cause to wakelocks caused by Google Play Services. I went ahead and attempted to resolve the problem by limiting said wakelocks using Amplify, and also by attempting to block certain Keep Awake permissions with AppOpsXposed.
This approach did give me an improvement in battery life, but the phone would still not enter deep sleep.
I kept searching for any information about possible culprits, and came across an older thread about Pebble and it's associated app causing abnormal battery drain. I did not think this could apply to my situation because a) I have been using Pebble for a year without these issues, and b) I was not seeing any statistics in BBS that related to Bluetooth (though probably it was there, and I just failed to realize it).
I proceeded to simply disabling Bluetooth, just to see if it would make a difference. It did. Immediately my phone started deep sleeping again. Next I thought that since I had used the Pebble with no issue for a long time, something had to have changed, and then I remembered that I recently changed to a new watchface. So I reenabled Bluetooth, allowing the Pebble to connect again, and unloaded all custom watchfaces from the Pebble. And now it works like it should - Pebble is connected all the time, and my phone still deep sleeps.
The last thing I have done is to attempt loading a new custom watchface, and so far it seems to be trouble free. One difference is that this one does not display weather, which seems to indicate that pulling weather updates from the phone may have caused the watch to keep the phone awake, but I can't say whether this is a general issue with weather updates on the Pebble, or a specific issue with the coding of the specific watchface.
So in conclusion, if you experience similar issues, I recommend trying the above solution.
Hopefully this information can be of use to someone
Dear all,
I am writing this post to hopefully get some help or directions regarding my issue, because I have already spent hours and hours looking on the internet trying fixes on my phone without anything working for me so far.. So I am getting a bit hopeless....
I recently got a Samsung Galaxy S6 (SM-920I model), and since the beginning i have been shocked by how CRAPPY the battery life was. To give you some ideas, my phone loses around 3-5% of battery per hour when idling and screen off, meaning I am not doing anything at all with my phone. Overnight, I lose about 15-20% battery with my phone on airplane mode, power saving, or whatever else you want, when it is not doing anything at all..
I know that my problem is a deep sleep problem, quite easy to identify i guess, so I have spent a lot of time reading and trying to fix it by myself but so far nothing worked.
To give you some background, after unpacking the phone I quickly upgraded Android from 5.0 to 5.1.1, so I cannot tell how it was working at 5.0. It is only after that I saw that a lot of people have issues on 5.1, but it is strange because just before having my S6, I was having a OnePlus One on 5.1 and I didn't have such battery problems and everything worked fine except turning off the "keep awake" setting option for GooglePlayServices.
What I can say though, is that since I upgraded I never had so much difficulties trying to fix a problem on any Android phone than before. Basically, since day 1, my phone never went a single time into deep sleep mode.
So far, to fix this, I tried all the following:
- Reflash the stock firmware (Samsung 5.1.1) --> many times, with full Cache/davik wipe and factory resets
- Root my phone using UniKernel
- Install custom ROM (I am running XtreStoLite version 2.2) + all kinds of wipe/factory reset
- Flash different kernel that are shipped with the ROM (there are 5 different ones if I remember)
- Use my phone with only stock apps (to see if the problem comes from one of my apps)
- Cold reboots
- The "DeepSleepFix" using the Android terminal as described on some forums (cannot post the link for now since I'm new..)
- And desperately, try to use my phone normally for now
Overall, I would say that my battery would last roughly 15 -20h in total with normal usage, not even heavy, which quite sucks..
I can show the no deep sleep issue easily to you with some screenshots (will put a link to the screenshots here when I have 10 posts... for now I can't..) , I have tried many applications to try to find the root cause such as:
- WLD
- 3C CPU
- BetterBatteryStats
- GSAM
etc.
I am monitoring my phone closely for the past 1-2 weeks and so far I have never seen it being in deep sleep at all (ah yes... 0.2s in total max all the time..). Also, when I check on the default Battery menu of Android, after a full day I would usually see "Android OS" on top and using 20-30% of the battery at least.
The problem seems to boil down to a process called "LHD" in the kernel wakelock. This is keeping my phone awake 100% of the time, whether I am using the phone or if I am not. However, even with this info I tried to search online and I cannot find anything about "LHD", so I am really stuck right now.. Do anybody knows what it is and why it is a problem for me?
If any of you have a solution or can give me some guidelines to help me fix this issue, I would really appreciate any help. If you need more information from me also let me know.
Thank you for taking the time to read me,
Best regards.

This thread is closed.
I am running into a Wakelock issue and I am completely stumped. For some reason, my phone refuses to go into deep sleep for hours on end. Better Battery Stats shows that the phone spends the majority of its time with the CPU at its lowest frequency, but refuses to go into deep sleep. The issue started when I clean flashed LinageOS back when I tried 14.1. Since 15.1 has recently released, I tried to have another go, yet the problem remains. I am using a Oneplus 5.
The very weird thing about these Wakelocks is, is that they are completely invisible. Wakelock Detector isn't showing any specific wakelocks (Advanced mode enabled), but does show that the phone isn't entering the deep sleep state. Not even for a single second. Better Battery Stats shows the same thing, with zero seconds spent in Screen off (deep sleep) and all the time spent in Screen off (Awake). No application is listed anywhere that's causing these wakelocks. They aren't visible under partial wakelocks nor kernel wakelocks.
Now this is where things get bizarre. I tried removing all my applications and reinstalling them one by one to find out if it was an app that was causing the issues. Each time I installed an app, I would check whether the phone would go into deep sleep when I wasn't using it. It turns out that the phone stopped going into deep as soon as Whatsapp was installed. Yet Whatsapp would never register more than a few seconds of wakelocks each passing hour.
I'm not sure where to even begin to try and solve this issue. Has anyone else ever experienced these kind of invisible / hidden wakelocks, and if so, how did you manage to fix these issues? Thank you very much in advance for helping me out
Nobody with a similar problem to mine? It's really killing battery life for me

I think I may have something similar happening with WhatsApp. My stats show lots of time spent with CPU on and screen off. Wakelock detector shows WhatsApp at the top of the list. But I don't really understand how to solve it other than deleting WhatsApp, which I don't want to do. Did you get anywhere with it?

No, I still have the same issue unfortunately. Though my issue seems to be slightly different than yours in the sense that Whatsapp is very low in the list. The total minutes of Wakelock is far below the total minutes of awake (screen off). But uninstalling Whatsapp instantly solves the wakelock issue. Out of interest, what phone are you using and what rom?

Redmi Note 4, Pixel Experience Oreo 8.1
I got here through a google search. I am not sure it's whatsapp causing this (haven't removed it yet) but on a Moto G3 with LOS 15.1 unofficial by Rahul I have the same symptoms.
Hello all,
many of you probably have no idea, that there's a small issue with our phones regarding tmd4906 proximity sensor. But first things first. Since I switched to oreo, I've noticed that something's eating up the battery and its sth related to system process. So I installed gsam battery monitor and started checking the lists. I came across that in android system, there's an entry regarding proximity sensor which is taking battery like crazy. Then, I was searching for the cause of it. And i found that's pretty easy to reproduce for us all. So I ask you to check something:
switch on your mobile data, find a dark place, turn on, i.e Spotify and start listening to music (mobile data has to be in use), turn off the screen, and point any other's phone camera to your phone where proximity sensor is (left to the speaker, up.). You should be able to see that proximity sensor is constantly working when mobile data is in use.
Another question - is there any other way to get rid of this? I have switched off everything which may make use of this sensor - no go. Since I'm unrooted, I cant do nothing about it. It's keeping making wakelocks like crazy and draining a lot of juice. My Samsung A5 2016 uses half less juice when i keep mobile data on.
Yes, I've tried many clean flashes from scratch - nothing. I came across that similar issue was found in s7.
Have you tried disabling "Block accidental touches" in Settings / Display ?
I my S7 Edge i had that too. Made my "Android System" wake like crazy. Only working solution was install different ROM (official)
