Hello! I've been lurking around trying to solve my battery drain issue for two days without success. I have a d2att with severe battery drain, where battery would last for around 2 hrs MAX before shutting down at 40%. This was apparently an issue before (my brother was using it) when it was on stock unrooted 4.3. I installed Carbon 4.4.4 to look for improvements.
Symptoms:
Rapid battery decrease during use
Shutoff at 40% (when rebooting it would show 0%, when charging it will start at 40%)
Constant wake (I believe from the systemupdate wakelock that is unstoppable)
Feels warm during short times of use, cool when standby
Attempts to fix:
Using GSAM to monitor battery drain (just installed Betterbatterystats, will update with that info later)
Installed MyAndroid Tools and Disable service to stop systemupdate and checkin services
Autoruns to stop all systemupdateservice receivers
Dalvik cache wipe to try to fix the 40% shutoff
Privacy guard to turn off keep awake for Google play services and Android system
Privacy guard to turn off location for GNow
Have not done:
Replace battery (just ordered one that's coming in two days)
Clearing batt stats, as apparently that doesn't help
Factory reset, as it's a pain to setup again (Should this be next?)
Greenify
Xposed
I am just generally confused at this point at whether systemupdate service is turned on or off, or how to solve that, or if that is even the main problem, and what my next steps should be. I'm not an expert and can only understand half of what's going on, so any advice is greatly appreciated!
*Update: It seems that the phone is able to go to deep sleep (~50% of the time). When I use it just 5 minutes for texting, the battery can drop 5%. After reading from another thread, I re-enabled systemupdate services from Disable Services/My Android tools to see if that would solve the problem, and it looks like it is not hogging wakelock anymore; however it does revert on boot, similar to this: forum.cyanogenmod(.)org/topic/96459-systemupdateservice-wakelock-on-cm11-m7-massive-battery-drain/
Update 2: I flashed Liquidsmooth 3.1 stable instead. This time I used autoruns manager and wakelock blocker (included in liquidsmooth settings) to disable the services, but systemupdate service still manages to run, so I have to disable the block to somehow make it stop with every boot. Once that is fixed, deep sleep functions normally, but now the new problem is that Chrome browser app seems to be stuck in an AudioMix wakelock. I uninstalled Chrome updates and this seems to have fixed that issue, however battery drain is still severe (5%/2min) during active phone use. No application stands out in constant wakelock anymore, so I'm suspecting it may be the battery itself? I will switch to a new battery tomorrow to verify.
Update 3: Well since no one bothered to help, I will just post this for future reference as a log, since I solved the last part by the battery switch to an Anker battery. The phone still gets hot, and I still have to manually deactivate systemupdate service on every reboot, but now it runs for "normal" times 5-6hrs (heavy use).
To be honest, it sounds like you had a failing battery. It happens.

theres an xposed app called amplify that helps to block some wakelocks , startups and alarms. it might help.
"all i can really do , is stay out of my own way and let the will of heaven be done"
First of all i have tried factory reset. Im using elementalx kernel on android 4.4.4. I don't remember my custom rom's name but it was cleaner version of stock. No im not going to update to 5.0. I have tried disable some wakelocks from google play services and disabled all possible syncs. But Google keeps enabling sync for location reporting and History reporting even though i have disabled it many times! Evert single time im connected to wifi or any other way to net it soon gets enabled and massively drains battery! 70% of battery had drained in 3 hours! I hadn't even touched my device on that time. I'm sure there is way to fix this but i don't know how. I have searched everywhere but nothing worked.
Edit:
Used Wakelock Detector and found out systemupdateservice and some alarm thing are on top of list. Appereantly there is some sort of bug with systemupdateservice so its always disabled. I enabled it because thats supposed to fix it so now let's wait if its the cause of problems.
Hello everyone,
I have a Nexus 5x with android Marshmallow 6.0.1, and for a long time now I'm having problems with Doze feature overnight. On a regular basis when I'm going to sleep - I turn off wifi and mobile data. Some mornings I wake up to see that battery was drain by almost 10% even though doze was active some of the time.
I attached the graphs of "Battery Historian" for last night. Though the battery drain is not horrible in this case, there are two things that I don't understand why they occur:
1. between doze periods, GPS is turned on. On my device "Location" is off and also "WiFi scanning". When I checked which app used GPS during this log, it says "com.waze", which is the domain of the Waze navigation app. However, even if one of its services does come to life between dozes, I don't understand how it is able to turn on GPS location without my active permission. I should say that some night another app will do that, like Tinder.
2. One wakelock that governs the wakelock charts is RILJ, which I understand is connected to location approximation using cellular networks. While the first problem I mentioned happens to me for several months now, this wakelock appears in the logs only recently. I think it relates to an app I recently installed called "Smart Wifi Toggler" which is supposed to automatically turn WiFi on/off depending on approximated location triggers. I uninstalled the app the same day I installed it, however since then RILJ wakelock always appears in the logs.
Last, I wonder if I should upgrade to Nougat. I understand Doze is better utilized with it, but I heard many users desire to downgrade back to marshmallow. In the case I do upgrade, I will perform cache and memory wipe so I don't know what will happen to these bugs. And the researcher in me still wants to know the sources of these errors.
Any help with these matters will be greatly appreciated.
I don't want to go through the whole process of wiping the phone and changing rom or permroot, is there a way for me to troubleshoot the problem of bluetooth drain screen off? Ive uninstalled every app I can and had wakelock detector working at one point... is there a way to get root temporarily so I can use betterbatterystats and figure out what is draining the battery screen off?
yesterday I removed and readded the google account since wakelock dectector said google services was waking a lot, so far today no bluetooth in battery use list and seems better will monitor.
The wakelock is called "BSS_InDisplaySensorHelper", it just appears since few days ago and drain lots of my battery. It's found under Android System in better battery stat. Does anyone know what it is and can I stop it?
Thx a lot
I have discovered that the wakelock comes from process to show the fingerprint icon on the Always On Display. In fingerprint options, if you disable "show on AOD", that wakelock will never raise again.
