Deleting some system apps cause battery drain, is that right? - Xperia Z5 Q&A, Help & Troubleshooting

I want to find what is best for me, so tried many combinations for better battery life and performance. I can't write complete list, already mentioned by @LolaPalocz and @GenomeX. Thanks for the list.
List 1 : https://forum.xda-developers.com/xperia-xz/how-to/huge-bloatware-list-xperia-xz-detailes-t3578758
List 2 : https://forum.xda-developers.com/showpost.php?p=67050458&postcount=3
I realized that some Sony's bloatware apps caused battery drain if deleted.

I think they do. Some services work together. When we delete some apps other services get errors again and again, so phone will not deepsleep... I see that on Logcat, so basically they do battery drain.

for me, on MM 6.0.1 uninstalling those system apps doesn't cause battery drain.
Check betterbatterystats and logcat to see if there's a recurrent wakelock / errors

Google play services wakelock after update 6.1.74

After updating to latest version of Google Play Services I have started to notice some sort of partial wakelocks. After 6hrs use I've got 44mins wakelock by google play services. Has anyone else noticed such behaviour? I have tried Purity Rom, Cm and Carbon just incase if there's difference, but I've encountered the same wakelock always. Here's what wakelock detector shows

Edit:thanks!
wakelocks are how your phone works, they are supposed to be. an occasional incident might happen, and a process will get "stuck", which could keep a wakelock active. tell me, your wakelock, is it draining battery faster than usual? a reboot will usually fix these kinds of incidences. but you say you flashed roms since, and still the same.. so my next question is which apps are you using that is using this wakelock?

Afaik I don't use any apps that trigger these wakelocks I've experienced. The only solution I've found so far is to disable services called "Configfetchservice" and "userpresenceservice". I've got these wakelocks no matter what ROM or even if I had disabled all Google stuff (sync, location, device manager and so on). Always after a day I have about an hour of Google play services wakelocks by userpresenceservice and configfetchservice. Never had this before. I'm sure it has something to do with latest google play services versions. I know wakelocks are very important part in smartphones but these kind of wakelocks are everything else but wanted.

so you are saying that these wakelocks exist for you.. one very important question to an answer you havent mentioned at all, are these wakelocks causing battery drain?

Not really shocking drain but noticable it is, which is nothing exceptional. It does these wakes during deepsleep every now and then. And of course when device is not used much and there is google play services on top 3 consuming elements at settings-> battery that's not the way it should be. Now I'm going to enable those services again and look for the logcat if I could find out to which app it is related to.

if its draining some battery, but nothing in large amounts, i wouldnt really worry about it. as sometimes these wakelocks appear, then disappear a week or two later.

I guess you're right. I'll just keep those services enabled for a week or so and see wheter it goes away or gets nasty and drains my battery in couple hours.

a while back, these kinds of things drove me crazy. then one day i just decided not to think about them anymore, and have been better off since. sure, every once in a while(rare, usually location oriented) a wakelock will appear that will drain lots of battery, but ill just use the disable services app to kill that wakelock for a week or two, then ill switch it back and all will be normal.

[Q] Help! Google app is draining my battery!

Hi guys,
In the last few days google app is draining my battery. It is disabled for wake up and keep awake in privacy mode, I tried to calibrate the battery, nothing helps. Even when I put it on flight mode, the draining is insane!
I attached screenshots.
My phone is not rooted, and I cannot root it.
Thank you all in advance!
I uninstalled it. I do not ise the cards and voice assitant plus I am an old fashioned guy, using search function in Chrome. By the way I saw other people having this issue, but don't know if it was resolved.
Yeah same for me, mine has been draining so fast when the phone is idle too! I'm running xnph05q cm11.

For chrome, you can do the same thing as suggested above
Android OS and Android System.. You can't do anything with it.. If you play with them, you'll end up making your system malfunctioning..

So do you suggest to uninstall updates only for a few days and then update it again from Google play?
BTW I have another wiered thing, I am on battery saving, GPS is off, and when I go to battery usage, it shows GPS on...

Hi there,
Until I will have a report regarding your previous suggestion, can you please take a look at my screenshots and tell me why the GPS is always on when I am on battery saving all the time?
Something is draining my battery, I get only 2:30 SOT, in the best case, without games videos music or even phone calls.
Thanks a lot!

As you have not rooted your bacon, only thing I can suggest you is that with the help of Privacy Settings, disable access for wake up and keep awake for the apps which are not oftenly used and also Google Play Services
Battery saver mode disables background services of the apps and lowers done the device performance
Combination of above stuffs can help you increase your battery life to some extend
Your GPS is not always ON as seen from the chart

Battery drain - Facebook?

I have been having battery drain issues lately. Where's the problem and how may I solve it? I believe it is because of the Facebook according to the stats, but I cannot simply uninstall it.
try in phone settings acoount facebook disable sync !
While you cant uninstall the facebook app anymore which I know is frustrating you can disable it completely. This will prevent any of its basic functions from trying to run in the background which are whats causing the battery drain. Whats crazy is that its been reported that facebook wastes up to 17 percent of daily battery usage on our phones. Here is how to disable it completely if thats what your looking to do.
you can also use package disabler pro and disable it. when you want to re enable it it is easy.

Combined App CPU draining battery

I get tired of talking about this issue after updating my S7 to android Nougat.
My screen-off draining too much battery. I've deleted cache partition and reset app preferences but i don't see any changes.
I've checked with GSam and it shows that Comibined App CPU used battery a lot (about 80%).
I wonder if you could help me on this issue

Hi mate
That information is not enough to solve the problem you need an app like BBS to find out who is the culprit....let it run for a few hours and check the logs....from there we can take action
i am also having the same problem. combined app cpu 80-90% also my download manager and mtp host, media manager are draining battery. when i disabled those, it helps but the i cant access Google play or anything on sd card.

Having bad battery life on Nougat? Check this.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​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
