Any ideas on managing the wakelocks on Android and specifically on the Infinity?
I've checked the option of switching off WiFi with screen-off, but in my battery usage stats I still see that over 10% of battery is consumed by Google Services with 672 wake locks & device waked 77 times (WiFi drain itself is 13,5%, so quite OK). This is what GSam Battery Monitor shows. Android stock battery management (in Settings) shows 51% drain by Google Services and 26% by WiFi (but I believe these stats are wrong most of the time or just measure a different thing, as they show tablet inactive with 2% bar and it has been inactive most of the time actually).
I have google auto-sync on and I need it, but I still think this is too high a number. I don't get 672 e-mails daily, so these shouldn't be PUSH notifications etc.
I'm not sure if I'm the only one seeing these high numbers there?
Have you tried CPUspy for finding out how much time in deep sleep you have?
Better Battery Stats is also a needed tool to find more about wakelocks

Yes, I'm looking at it from time to time, but thanks for this. I had some issues when I started this thread, after wipe and re-flashing new firmware it seems OK in the stats: Deep Sleep 44%, 102MHZ 16%, 1500MHz 24% (running on balanced mode, interactive governor).
I'm still curious to get to know how to manage wakelocks under Android from (low) system level however.
Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Maps, Google Fit, Google Now, among other things.
CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

From what I read on the Play Store description, Kitkat and above requires root?

Try clear cache+dalvic cache in recovery
Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.
Hello all, I recently noticed that my OPO was not going into deep sleep. So I installed wakelock detector and to my surprise, nothing out of the ordinary was going on. I proceeded to wipe the dalvik and cache, still nothing, won't deep sleep. Last night I flashed franco kernel in the hopes that it would solve the problem, guess what, nothing, still won't deep sleep. The phone just drops to 300mhz and stays there for the minimum frequency.
I'm running liquid smooth 3.2 (4.4.4) with the recently flashed franco kernel.
Do you guys have any other suggestions on what to do?, I was just about to flash an entirely new rom and keep it barebones till the end of the week when cm 12s and oxygen os are released.
I'm experiencing exactly the same issue..

Maybe the PlayServices are the Problem somewhere here is a guid to prevent them to keep your phone awake
Actually play services did not come up in the battery stats to indicate it was indeed active. I ran through anything, there is nothing causing unnecessary wakelocks. So that's why I'm confused.

Play Services doesn't always show up as Play Services in the battery stats page in your settings menu, it quite often will show up as Android OS.

Not even that, as I said there was nothing android related nor was there any app in wakelock detector that was showing signs of a wakelock. For good measure I did follow the many guides on stopping google services etc. and none of them worked. Phone still won't go into deep sleep. Strangely enough it was wasn't affecting my battery life that much, was still getting about 6hrs on screen time with 14% battery left.

Sounds to me like your battery stats might just be screwy.

So now I'm wondering, as well. What would an example of good/excellent deep sleep look like? % drop over time?
My battery stats show cell standby at 1%, phone idle at 1%, and over over eight hours go from 100% to about 86%. Would that drain be considered deep sleep, or good deep sleep?
I had a similar issue and able troubleshoot successfully.
Device:
- POCO F1
- MIUI 12.0.3.0, Android 10
- Magisk 21
What tried but didn't help
- There is no wake-locks active
- Tried Battery Saver and Ultra Battery Saver
- Tried Airplane mode
- Tried rebooting
- There is no significant battery drain (only 1.6% per hour)
- Tried disabling Proximity sensor
- Tried wiping dalvik-cache
I have followed the guide by Intel at https://software.intel.com/content/...-no-sleep-issues-in-android-applications.html
As I mentioned earlier, there is no active wakelock, that is why the troubleshooting was much difficult.
I have digged into `/sys/kernel/debug/wakeup_sources` and sorted processes based on the column `prevent_suspend_time`. The process `qtidataservice` was on the top. Not sure what it is, but it's probably from Qualcomm and running under the `radio` user.
The `strace` was showing nothing. I have simply killed that process. It's eventually re-created with a new PID. Interestingly the device began to go Deep-sleep while in idle.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------What I have right now out of Doze are "Bluetooth MIDI Service", "Bluetooth Share", the "Clock" app and two other Clock apps.
I am not sure how effective is the method listed below after the last update. Stay tuned.
Also I think the current version of Facebook Messenger is draining too much battery.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Hello everyone,
when I bought my Zenfone 3 ZE520KL, I was amazed by it's battery life. I could easily get around 8 hours of SOT in a single charge with moderate usage. My device was running Android Marshmallow 6.0 out of the box, but performance wasn't as good. On Nougat, performance is much better and faster, also I used to get some lags and frozen screen, the capacitive keys also sometimes froze when I was charging my phone, but now I don't get issues like that as often as before. Interface is so much more appealing and I love it.
But what about battery life? I started getting around 5 hours of SOT.. which is still good, but not really close to 8 hours. I thought a lot about these 3 hours that were missing so I decided to start investigating. I wanted to share my findings with you so maybe you would know something that could help.
It's been two weeks since I have been testing out different things. The apps I used to do my research are:
Carat. What I love about this app is the process list. It shows exactly which apps and system processes are running in the background, so I can control them very easily.
Greenify. Thanks to the Carat app, I can see which apps continue running in the background, so I can use Greenify to hibernate them after I'm done using them. (Examples: Youtube, Snapchat etc.). Also I bought the Donation Package, and unlocked the other modes using adb commands (my device is not rooted).
BetterBatteryStats. This app is usually used to detect wakelocks. I limited the Google Calendar App from syncing so it doesn't use too much battery in the background. This app is paid in Google Play but you can get it for free from here.
What I did to get better battery life:
I excluded the services, that were always running in the process list from the Carat App from Doze. Apparently, the new Doze in Nougat gives us permission to optimize more system processes and services than before, which can backfire - Doze starts trying to kill processes that can't be killed, and this results in consuming more battery juice than saving it.
How to enter Doze settings and make the following changes:
Go to "Settings" > Select "Battery" > Tap on the three dots at the upper-right corner > Select "Battery Optimization" > Select "All Apps" > Find and tap on the Apps/Services/Processes I have listed below > Select "Do not optimize". The other apps and services should stay optimized.
The apps, processes and services that I removed from Doze are:
Android Services Library
Android System
ASUS Calling Screen
Bluetooth MIDI Service
Bluetooth Share
Camera
Clock
com.android.smspush
com.asus.keyboard
com.asus.shim
com.qti.qualcomm.datastatusnotification
com.qualcomm.qti.tetherservice
org.codeaurora.bluetooth
org.codeaurora.ims
com.qualcomm.qcrilsgtunnel
ICESound Service
Mobile Manager
MobileManagerService
System UI
Telecom Service
Telephony Service
ZenUI Keyboard
ZenUI Launcher
Some other apps that I'm using: Do It Later, Greenify, Messages, Nova Launcher, Timely, Weather.
Please do a full charge to 100% afterwards and check if the battery still drains as quickly as before. Your feedback will be greatly appreciated.
I am already starting to see improvement in my battery life. I was losing around 2% on Stand By and battery was draining fast when I was using the phone, but now I lost 0% on Stand By overnight and 10% for 1 hour of SOT (before this I was losing 10% for 30 min. of SOT). I am still trying to figure out which services exactly are causing the drain, when they are being optimized. Maybe the services, included in the Android System? (Check them from Settings > Battery > Android System > Included Packages). I deleted Facebook and Twitter apps and started using them from Chrome (almost the same thing, I quickly got used to that). Please check the updates below for more info and share your opinion or advice in the comments so we can all reach a better experience with this amazing smartphone.
Thank you for reading!
Update1: 6h30min SOT with 30% left (917mAh, 35%), but I will have to charge now. I have been messing with Doze a lot, maybe I'll get more clean results later. Progress has been made though, at least with my device.
Update2: Something interesting - my J-Score with the Carat app before and after starting this experiment: http://i.imgur.com/Q8u6HBD.jpg
Update3: There is a battery drain when making voice calls - 226mAh (7%) were lost because of 43 minutes long talk time.
Results were worse after testing with the second list removed, although there wasn't much draining with the screen on: SOT - 5h20min for 70% of battery (752mAh, 20%).
Update4: com.android.phone appears as a wakelock at BBS (Wakeups:8). Also 2h30 SOT for 30% used battery (100-70%~408 mAh). I'm updating the list and trying again.
Please note that my phone is updated to the latest firmware WW_Phone-14.2020.1703.28-20170410.
Update5: com.android.phone is still an active wakelock (Wakeups:14), but SOT is 2h34min for 30% used battery (100-70%~343mAh). At 30% battery left, SOT is almost 6hrs(28%~787mAh), Device Idle is at 10% (291mAh). The MobileManagerService is causing way too many wakelocks and is probably the reason for the high Device Idle battery usage.
Update6: MobileManagerService is no longer showing as a frequent wakelock. com.android.phone (Telephony Service - Wakeups:9) and com.google.android.apps.messaging are the most persistent wakelocks, other than that battery life is amazing at the moment. SOT is 2h45min for 30% used battery (100-70%~366mAh). I also had 27 min of talk time (4%~145mAh). At 30% left, I have 6h33min of SOT (32%~912mAh). Device Idle is again at 10% (292mAh). We are ready for the final test.
Update7: The results are quite interesting. After removing com.qti.qualcomm.telephonyservice from Doze, com.android.phone stopped appearing as a frequent wakelock at first, but now, at 70% it has 16 wakeups. SOT is 2h22min (100-70%~318mAh), so it's not better. I'm going to try a few more changes.
Update 8: I posted it as a reply here.
Update 9: I shouldn't have put Task Manager out of Doze, I get so much better battery life now. The update is ready, check it here.
Good post, thank you for investigating this, please let us know if you find more stuff or what exactly is responsible for it and an easy way of fixing.

Hello! Thank you for your reply. I'm so happy I could help others and myself with this thread, but I also need to know if you are also seeing any difference. Please check here regularly!
Also, I'm guessing that when you put your system processes and services in Doze, you also decrease their performance, which causes battery draining, as they try to run normally and do their work. Doze is trying to prevent them from doing that. This is my conclusion, but only results will show if I'm correct. If you own yourself a Zenfone 3, please feel free to report if you experience any changes using my method.
Thank you and have a nice day!
Hi, thank you for the post. I have a zenfone 3 here and will try your method.
I'm trying it on ze520kl with marschmallow, it seems working fine. :highfive:
Do you remove the first and second list from doze ? or ate testing with only the second list now?
Nice findings btw

Too early to say, also I got a weird wakelock, and lost 2% overnight. I lost the results (100-90%) after a restart. Now I'm going to update my phone and start again.
I had 8% used up on 43 minutes of SOT, and 2% lost on voice calls (100 and something mAh). I went to bed with 92%, I guess the other 2% were lost on that wakelock and the clock wakelock. These 2% were lost on equal intervals.
It's going to take a while, I'm just using my device normally. I don't have time to be on my phone all the time, also the battery is harder to drain now. At this point, I'm just trying to get better results.
Cheers!

I don't think it is a good ideea to change Doze settings for system services like com.qualcomm.* or telephony*.
In theory, these services should be compatible with operating system and they should work as designed. I would focus on third-party apps who doesn't work well on Nougat.
Anyway, is just an opinion and i'm looking forward for updates

Hello ci6i, I also agree with you, and that's why I excluded all of them from Doze when I first tried this out. At the moment, I removed only those system services, that run in the background all the time. My goal is to find the least amount of system services and processes, that are causing battery drain when the phone is in use.
I am not saying that you should do exactly what I did. It's best if you try out yourself on your own device what works and what doesn't.
I also have only excluded from Doze apps that I use daily. But everyone is using different apps and it depends only on the developers to update them.
You can download Carat for free from Google Play and check the process list, it's very useful. The app itself doesn't use any battery.
Good luck!

I agree with you and i really appreciate your work Yesterday I've installed Carat after i read your first post and today i did new OTA update and cleared cache partition. Let's see how it works in the next few days.
What should I do next, guys? Remove other com.qualcomm/com.android/com.asus services or remove just MobileManagerService from Doze? I'm thinking about the second one, I'm curious to see if ti makes any difference. I think the results from the first test were the best, and the MobileManagerService was out of Doze as far as I remember. Might as well try and see what happens.
It's a bit hard to drain the battery these days, so updates might not be fast. Patience is key!
Yeahh final test!! Looking forward to the result
OneUI built-in Device Care app doesn't show full details of what is draining battery. It fortunately shows the Screen ON Time (SOT) though.
My phone's battery drains badly on standby. It drains anywhere between 1.5% to 2% per hour on standby if I leave all radios ON. If I turn OFF WiFi, Mobile Data, Bluetooth, Location, etc. then the battery drain reduces to 0.5% per hour. There is no unusual drain when I'm using the phone. If I'm continuously using the phone, I can get 6 to 7 hours SOT.
The built-in battery stats doesn't provide full information on what is draining battery, and how much. For example, it doesn't show system functions like Android System, Android OS, Display, Wakelocks, etc. It only shows 3rd party apps installed.
If I add the % consumption of each app shown in the list, it won't even add up to 50% of actual consumption. If you see the attachment, the sum of the individual consumption adds up to about 20% only. My battery is at 59%. So I have no idea about what used the remaining 21% (standby drain).
Assuming that all details are available in the system, is there an app that can simply read this info and show it on screen? I don't want battery 'monitor' apps that run in the background.
I'm interested to know if there is an app that would simply read this information and display it when launched, and won't run in the background when closed.
Thanks.
Gsam battery monitor, better battery stats or Battery guru. But i think that they all need to keep a background service, which doesn't cause any noticeable battery drain though

I seriously doubt this. It is just that they don't show up in the stats.
From my experience, there was no difference in idle drain battery usage with and without any of these apps. Checked for some days, not only a few hours.
