Increased Battery Drain after Jellybean syncing update

I noticed that, after Google pushed out their update to include additional Account syncing options (App Data, People details, etc.) that the auto-sync is much more aggressive. Where I used to be able to get through an entire day, I now find myself at 20% battery after just 10 hours.
At first I thought this may be an issue with my Viper 3.2.7 + ElementalX 6.5 setup, so I did a clean flash and ran the stock kernel for a day, with no change. I flashed CleanROM 6.5 today and it's still exhibiting the same behavior.
To be more specific, "Google Services" shows up as >50% of the battery usage when I look in Settings>Power>Usage.
Anyone else been seeing this?

i've had way worse battery life after updated to a cm10.1 build from a week or two ago
and my google services is much higher up in my battery stats than normal, so you may be onto something

me too
Yes, it started for me yesterday. Android OS taking >50% battery, typical, but Google Services now taking >35% battery. Full battery drain in 12 hrs, normally can last 36 or more. I too noticed the new sync options, and disabled App Data and People details. Hopefully that will help, but I doubt it.
Running CM 9 on an ATT Samsung Galaxy S2 (US version, not skyrocket).

I disabled all new syncing options as well, with only Gmail, Calendar, and Contacts synced. With this configuration, my battery only lasts 12 hours on Clean Rom 6.5, whereas it used to last >20
There isn't really anything we can do from the user end. I guess we'll have to wait for some ROM that uses a less aggressive sync strategy?

[Q] "Android OS" hughe battery drain

Hi everyone,
These days the battery consumption of "Android OS" process has been quite high. Last days it has been around 30-40%, but today, it reaches the awesome figures of 70%.
I have francokernel-r32 (last one) which everyone reports it's a battery friendly kernel. Obviously I notice no difference between francokernel and stock because of the Android OS battery drain. Also I have the CM11s-R44 stock.
Other little details: I use Greenify, cleanmaster and Amplify to save battery and system resources. Localization is fully turned off (I don't need it) and using 2G and WiFi networks (I use 3G just for few minutes/seconds to download or surf the web).
The xposed modules I have installed: amplify, bootmanager, complete action plus, greenify, whatsapp quiet hours and youtube adaway. I think none of these can be suspicious of battery drain.
Any suggest? I have no idea on facing this problem...
Thanks so much :good:
Edit: pictures are in spanish, but I think it's easily understandable (just the figures of Android OS process say everything).

Firstly, you say 'also I have CM11S-r44 stock', but you're not stock if you have Franco installed. Anyway, it could be Google Play Services that's causing the problems, have you tried this?

have you read the thread on r32 its been giving people some issues. May I suggest r31 and as previously mentioned are you running Google Now. I mean the the drain you see could be warranted. Also what the Keep Awake showing you? How bad is that

I'm going to piggy back off this thread. Android OS and Android System are killing my battery as well. I've turned off the Google Location Services keep awake and wake up (etc...as per Timmaa's thread), and I'm still getting a very large keep awake from Android System. Please see the attached screenshot.
Nothing else has been edited. I'm on 44R stock rooted.

Is this drain only when connected to wifi?

I'm not really sure actually. I'm connected to WIFI around 80% of a given day so my guess would be yes.
Do you know of something that could be causing the drain, or is that just what happens when you're connected to WIFI?

I have this issue from time to time when connected to my home Wifi. You could try by turning off Wifi for some time.
Rebooting the Wifi AP or changeing channel helps for me in that case.
Is it a hidden network?

Nope it'd a public password protected network.

Very Slow/Inconsistent Notifications

Hi, so the simplest way of stating my problem is when my device is either unlocked (AKA browsing apps and whatnot with the screen on), or locked (sleeping), notifications are slow to arrive. Right now I've been testing with Skype, and Gmail, both of which are inconsistent. My OPO does not currently have a SIM card (haven't setup the plan yet), and I've tried with both LTE and Radio off (using *#*#4636#*#* on the phone info page)
Info about my OPO/Setup:
Flashed CyanogenMod 12.1 as stated in the Sultan thread before flashing Sultanxda Rom

Using Greenify and Amplify with settings from both of these threads (http://forum.xda-developers.com/android/general/guide-0-0-hour-idle-battery-drain-stock-t2973588 & http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884)
My OPO does not currently have a SIM card (haven't setup the plan yet)
Things I've tried:
With both LTE and Radio off (using *#*#4636#*#* on the phone info page)
Older Skype versions
Push Notification Fixer (https://play.google.com/store/apps/details?id=com.andqlimax.pushfixer&hl=en)
Disabling Amplify by disabling the module in Xposed, and rebooting
Double checked that Greenify isn't touching Skype or anything related
I also have a Samsung Galaxy S3 that is using the stock ROM (Android 4.1.2) with root permission and a custom recovery. That is the device I've been using to test with. If I send a Skype or Gmail message from my OPO to the Galaxy, it takes 2-3 seconds EVERY TIME consistently.
If I send a Skype or Gmail message from the Galaxy to the OPO, sometimes I'll get the message within 3-5 seconds, other times it takes 1 minute+ and even a few messages don't arrive until I unlock the device and open Skype or Gmail.
When I leave Skype open, and lock my OPO, it seems to get the messages very quickly almost every time.
Also, it appears that when my phone sleeps for a certain period of time, seems inconsistent, the WiFi will disconnect - and I DO have keep WiFi on while phone is sleeping.
I've run out of ideas short of trying a full wipe and different rom/kernel/who knows what at this point...=\
Any/all help is greatly appreciated. Thanks.
Edit/Update: Found this post (http://forum.cyanogenmod.org/topic/107023-cm12121-wifi-connectivity-issuesdrops-workaround-included/) on another forum, and that seems to have fixed it for me. Doing further testing, but so far positive results.

The delayed response is most probablye due to the Greenify/Amplify tweaks that you've made. Remove everything related to Gmail, Skype, Google Play Services from Greenify & Amplify and then test. Add back the tweaks one by one and find the culprit.

I've already tried that. Fully disabling Amplify, and double checking that I've touched nothing close to Skype or Gmail or Google Services in Greenify's settings.
As I put in the edit in my first post, I found out going to /system/etc/wifi/WCNSS_qcom_cfg.ini and changing the line
Code:
McastBcastFilter=3
to
Code:
McastBcastFilter=0
appears to have solved the issue for me.
But when I did that, I also noticed something else, and I wish I hadn't unplugged my device (AKA wiping battery data so I could show a clear screenshot of what I mean), because I saw when I was looking at the battery usage chart, all day long while I had McastBcastFilter=3, my WiFi signal was turning on and off CONSTANTLY throughout the day, and sometimes for decently long periods. Now that I've changed McastBcastFilter=0, my WiFi signal shows that it's on 24/7 in my battery screen.
I'm worried that this is going to cost me a fair bit more battery, but at the same time I need my notifications.
I found another setting in that file with this comment:
Code:
# Enable suspend or not
# 1: Enable standby, 2: Enable Deep sleep, 3: Enable Mcast/Bcast Filter
gEnableSuspend=3
Before I made any changes to this file, it was set to 3, which makes sense with the McastBcastFilter changes I made. But attempting to get some more battery life so my WiFi goes into some sort of partial power save mode for battery longevity, I'm going to try my OPO with Enable Deep Sleep on all day. We'll see how the battery fairs and if notifications are still delayed or not.
Edit: I was able to get the data from my secondary battery app so screenshots for all!
This is what my Wifi/Battery was like before I changed McastBcastFilter at all:
Code:
imgur.com/ZXmFYhI
This is after I changed it from 3 to 0:
Code:
imgur.com/H5ZlXc2
And this is what it's been like since I rebooted last night with gEnableSuspend=2 (AKA Deep Sleep):
Code:
imgur.com/2O6GuVE
Obviously when the WiFi is off, I'm not getting my notifications. >=\
(Gave the URLs CODE tags so I could link the images...)

Well so far I haven't seem to have come across any issues with leaving BcastMcast at 0 and using Deep Sleep for WiFi. I'm still getting all my notifications, and as far as I can tell the battery life is give or take about the same. Possibly a little more battery drain than with BcastMcast on, but I haven't done any sleep tests yet, just initial observations with using OPO in a daily setting.

Faulty Battery or Software Issue?

Hi folks,
I scoured through all the battery related discussions and wasn't able to find an issue similar to mine, so I hope it's okay to post a new thread on this topic. I have an AT&T (Snapdragon) Galaxy S7 with stock software and about a month and a half ago I started experiencing horrible battery life. I have been desperately trying to figure out what the issue is. At first I thought it was AT&T WiFi calling because it was forcing my WiFi and data connections to toggle back and forth and disabling that did help. However my battery life was still poor and I could never get more than about 10.5 hours of moderate use (see pictures below). Also the phone gets hot randomly (Above 95 Fahrenheit) even when doing minor tasks like browsing through Chrome. Since then I have made the following changes with no noticeable improvement:
Disabled advanced LTE services
Disabled Always on Display
Disabled WiFi and Bluetooth location scanning
Disabled nearby device scanning
Wiped cache multiple times
Temporarily disabled Bluetooth and WiFi to monitor the difference
Used Greenify Aggressive Dose
Disabled all diagnostic reporting
Uninstalled Oculus when that battery issue came up
Side note: I disabled a bunch of bloatware right when I got the phone, not through Package Disabler but through the standard Android disable method
I kept digging and found that my phone doesn't enter dose unless I use Greenify, and even then I don't notice a difference. I then decided to do a hard reset but no luck. Afterwards I used Safe Mode to see if any 3rd party apps were misbehaving, but again the drain was consistent both while idle and while using the phone. Today I installed Wakelock Detector Lite and found that PowerManagerService is keeping my phone from dosing, but from what I've read online it seems that info doesn't really point to a specific app, and it's hard to identify unless I root the phone which I don't want to do.
I am going crazy trying to figure out if this is a software/settings issue or if I should just replace the phone through AT&T and risk getting a defective refurb. Any help would be much appreciated.

Many people have similar problems. One reason was the buggy oculus app (you might wanna disable that when it came pre installed, depending on your CSC).
However the main reason behind the high "android-system" usage is still unclear. Some people experience it, some dont. Some people have better battery results with the firmware from March.
Personally, I believe that it is firmware related. I tried the N7 rom port and did not have a problem at all.
You might wanna wait for the October update that will hit soon and see if this fixes anything.

I notice you have 'media server' showing in your battery stats. My wife had that showing too and also had terrible battery life. Her fix was disabling the auto streaming in her Facebook app which plays videos while you scroll through posts. Now she has great battery life!

I have the Facebook app disabled on my phone altogether. I've also used safe mode where 3rd party apps are disabled but the battery still drains at around 5% an hour while idle.

WiFi calling was draining one members battery, disabled that and everything returned to normal

I had that issue too but have since disabled WiFi calling

most likely a software issue. my version is G930FXXU1APEQ and i'm been getting 11 hour on batty with around 6- 7 hour of screen on.

Try disabling Google backup. It's a huge battery drainer

Try manually updating Google play services for the lastest ver sion.

Nothing has helped so far so I decided to uninstall my apps in batches until battery life improves. I'll then slowly reinstall them one by one until I find the culprit. I'll report back with my findings. Thanks for all the suggestions.

Galaxy S7 Android System Battery Drain Same As Screen

I have seen this post many times before, but never got a solution to what I am looking for. My Galaxy S7 is about 2 years old now, and no problems with it, have just loved this phone. Recently, I started having a battery drain issue where Android System would use up large amounts of battery. I had this issue on Nougat, and I recently updated to Oreo and the issue isn't fixed. I have deeply looked across the internet on different ways to fix it, and I have tried everything. I have tried wiping cache partition, resetting app preferences, resetting settings, factory reset, clearing data and cache from Google services, turning off background usage for android system, installing Gsam and looking to see what's draining it there, turning off all services I'm not currently using (Location, NFC, Bluetooth, ETC), checking cell signal, turning off backup data for Samsung/Google, not leaving Wifi on in sleep, checking and ending unnecessary running services in developer options, disabling bloatware, and SO much more. Nothing has worked. I get around 3 hours Screen On Time, which I feel is unreasonable. Android system seems OK in the background, but It keeps at the same battery drain speed as the screen. (example: my screen has 13% battery drain, meaning that android system also claims 13%) sometimes it is a couple percent lower, and sometimes higher, but usually close to the same. My sister has a Galaxy S5, and when she uses down from a full charge the android system drain is 3% which is a lot different from what I get. My phone even has a bigger battery than hers, but her's has no problem with battery drain. This is the T-mobile S7, running Android Oreo. Please don't suggest power saving mode, or a lot of limiting options on the phone. What's the point of a SMART phone if I can't use all these neat very useful features? I would be better off with a flip phone if I was going for only calling and texts. Please help me find another solution that will fix my problem.
Thanks in advance!
I could not upload a screenshot, but my battery stats are as follows:
Android System: 14%
Screen: 13%
Android OS: 9%
Youtube: 5%
A game I like to play: 4%
Device Idle: 4%
Cell Standby: 4%
audioserver: 2%
