With 12 hours of screen on time I'd say your usage makes the screen "always on" :p ...get it....cause your SoT is 12 hours....so its....always....on ....:silly:

Everyone can get 12 hours of screen on time, it just depends on how you use your phone. I'm on Verizon and I can get close to 6 hrs on heavy usage cycles with most services on but normal for this phone seems to fluctuate between 4.5 - 6 hours in between charging cycles for me, a working professional with a wife and kid where that SoT happens over the course of two days. During that time Android system will be guaranteed to suck up 15-20% of my battery according to my phone's stats. I think this is just how resources are reported on our SD820 and that's it.

Then we have people that cripple their phones, turn brightness down and run on wifi the whole time, and stream a season of something on netflix and absolutely they're going to get 12 SoT. With my usage pattern of around 2-3 hrs/day of screen on time and about two days total usage...to acheive 12 hrs would be 4-5 days off charge...now THAT would be something to brag about, unfortunately that's not happening for me nor for anyone else that uses their phone and is a regular member of society :laugh:. Would be glad to be proven wrong with some GSAM stats though....

Well, I meant the really bad battery drain people have been dealing with. Of course it will use some battery. But, now that I have my battery life under control, I can say with certainty that AOD is not what is causing the real problem here. I think even some of the steps I did take likely have nothing to do with it. Disabling the send security reports is what sent my battery life up to what it's at now. The other things did help improve it though.

Hi all,

Have Verizon S7 Edge.

"Samsung Internet for Android" just became available for download from the Play Store for me. If not in Play Store, search google for it, and install from there.

I installed it, set it as the default browser, make sure not to sign into Samsung accounts when first opening.

Disabled Chrome in Application Manager (had to uninstall updates first)

Re-enabled Chrome, and downloaded the latest update for Chrome from Play Store.

Did not sign into my Google account after I launched Chrome, and did not sign into my google account from Google homepage.

Been using Samsung's Browser ..

Android System around 18%, OS around 10% (down from 31%/18%) and dropping by the minute..

Worth a shot?

If anyone on Verizon does decide to remove the Google account, factory reset and wipe cache from recovery, let me know if you DO see a send Samsung diagnostics and usage checkbox during setup. I also wonder if removing my Samsung account then re-adding it would show me that option. I just want to be sure that one is unchecked too, but, obviously if it does exist on Verizon phones, it's been hidden very well...

Go to settings, language and input, text to speech, google text to speech settings, then settings for Google text to speech, turn off anonymous reports. It helped my battery I think, because I use Google search a lot. Hope it helps someone who missed it.

Anyone have an idea why after about a day my phone stops going into deep sleep? Here's the scenario...I cleared cache from recovery after charging to 100%. Phone goes into deep sleep and doze often. Once I get to 15-20% battery it stays awake longer and I notice the phone doesn't go to deep sleep. I've tested this theory twice already with same results. I have power save mode off as well.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
I've never seen this problem. Perhaps power saving mode is kicking on and messing up the Doze?
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
I can attest that around 20% battery left my phone starts becoming a bit sluggish. I wonder if Samsung kicks some power saving mode at 20%. Can anyone confirm?
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
I still have abnormally high battery drain on Android OS and Android System.

But, I can't complain about battery stats.

I'm at 50% battery:

- Off charger over 14 hours

- SOT over 3 hours

- BT on over 2 hrs and 39 mins.

- Phone calls for 2 hrs and 27 mins

- Location on (GPS, WiFi and mobile)

- Google Now launcher and OK Google On

-Sync On

- Always On Display Off

- I used Google Maps for 28 min drive to work.

No Facebook app but use Google Plus, Twitter and Instagram heavily.

I do not use Package Disabler Pro. I disable whatever available under Applications.

I did wipe cache, factory reset through recovery and started device as new.

I opted out of Samsung and Google diagnostics and feedback.

WiFi on during sleep set as Never.

I use Google Now heavily so location history on.

I hope this helps others.

Comparing to 3 other S7's in the office and I'm the only one that has high Android System and Android OS usage. I'm also the only one that has a microSD installed. I removed it today and I've been running for a few hours now. It looks like usage on these two is now significantly decreased.

When I first received my edge, android system would hover around 30-40%. Did a factory reset and now it never goes past 6%.
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Did you follow all the steps from another thread when you did the factory reset? How's your Android system percentage now?
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Just wanted to report back and say that I finally got the opportunity to factory reset last night and since doing so I have had phenomenal battery life (currently sitting at 85% with 1 hr sot and 5 hours off the charger) However, I also do not have my micro SD card installed, I will put it back in tomorrow and see if effects anything.
[Samsung Galaxy S7 Edge Questions and Answers] dmrnhs:
how? did you disable anything? also, what carrier are you on? It seems like many people have tried a factory reset but android system just drops a little, if any. might just be a placebo effect.

I just disabled the preloaded Facebook and Onedrive apps and turned off the voice activated google now function. Using the exynos edge on AT&T network.

I think my battery could be a lot better if my WiFi and phone radio wouldn't take 50%+ of my battery all the time. Help?
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
Yea I'm not sure. I've gone into the settings and don't see it turned on so wondering if it's something encoded by Samsung/Google?

I will try to recharge once I get down to 20% and see if my deep sleep is affected any.

Edit: I just check my deep sleep and notice it is still the same as when I got to work this morning so I'll keep messing around I guess.

[Samsung Galaxy S7 Edge Questions and Answers] RnGJesus:
GearVR

Has anyone tried disabling gear VR, just looked at it and it says that it's drained 13% of my battery (currently at 52%) so far. Maybe that's where the Android System drain is coming from.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
I've disabled a lot. Not sure how some people are getting Android System to 6% because mine never goes below 18%. But I can get 8 hours SOT with serious usage on auto brightness so I don't really care at this point.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
This is confusing a lot of people. All Android System apps show the exact same usage since they are bundled all together.
[Samsung Galaxy S7 Edge Questions and Answers] nyt:
This will report the same amount as android system I believe.

Yeah, if you're getting 8 hrs SOT, it doesn't really matter what % android system is using.

For me, I'm pretty sure the "Android System" battery drain issue is related to the fingerprint login option. My wife mentioned that her battery began to drain much more quickly once she switched over to using her fingerprint to login to her phone (we both have S7s). I tested whether this might explain the battery drain on my phone using Greenify, and I found that the battery drain on my phone drops dramatically when I stop the two apps that appear to be related to using one's fingerprint to login.

Like I said in another thread. I don't think the finger print sensor has anything to do with battery drain. I went 3 days without using it and then enabled it without noticing any increase in discharge rate.
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
Bluetooth and wifi definitely has some issue. My battery life just inconsistent. Some day can be good, like android system only drain 800 for whole day but some day it will drain 1600. Also, Bluetooth sometimes will joining and suddenly drain like 300 to 400.

What was your SOT for this? I would like to see, as your Android System is double mine but it looks like your total time on battery is quite long.
[Samsung Galaxy S7 Edge Questions and Answers] dmrnhs:
just chatted with samsung support and apparently they are aware of the problem and it will be fixed in the next software update for the phone. Hopefully thats true and hopefully that update comes quick. Not that my battery life is terrible, but its definitely annoying considering how excellent this phone is supposed to be.
[Samsung Galaxy S7 Edge Questions and Answers] Will.1:
Could it possibly be the "ok google" always listening on every screen that is the culprit ?
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Mine's on, and I'm getting around 35-40 hours of battery life. For me, it was the Google reporting and the Samsung send security reports. Once I flipped those off, my battery life went up a ton.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
The android system looks so high in comparison because I wasn't using the phone for anything else really. Therefore out of the total use, the android system used the most. The only reason my numbers look so good is because I had mobile data turned off for fear of going over my allotment.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
I never said your numbers look good, but I wanted some more information as people often post the screen you did with no other facts and it doesn't really help anyone.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
I realize that they don't look good, but you have to realize that number is just a comparison to other apps and I hadn't run any others and that is why that number looked high. It is usually much lower because there are other apps being run. Those numbers can be very deceiving and I don't like going by them.
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
Does anyone know how Samsung optimize battery usage setting work? See top right of image.

Any comments on actual results?
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
I believe that's where you select which apps you don't want to go into doze.

As far as results, I don't know for sure. I'm having to use package disabled pro to try and get my phone to sleep and doze.

Yes, this is the Doze whitelist.

I have plenty of bloat disabled and have taken two OTA updates already with no issues. My battery life has improved slightly since disabling bloat, but my Held Awake times have improved greatly.

Actually, it's not a PITA to just export your list, re-enable everything, take OTA, import list back. It takes like 3 minutes.

After factory resetting and clearing cache from recovery

After factory resetting and clearing cache from recovery about 3 times each back to back( just to make sure it's dead).

I have the Galaxy S7 Edge from Tmobile. All diagnostics report are disabled. Google is syncing everything except google fit and photos. Disabled automatic updates in the play store and did not update tmobile voicemail, nor the tmobile app. I havent even opened it as of yet.

As you can see, Nearby Service was on, I disabled it after I saw this. Even though Android System is holding my phone through the balls, it still came out a champ.

My location settings are GPS/WIFI/mobile networks all enabled. I do have Google Now open, but not any screen enabled.

During this time period, I did facebook, reddit, instagram browsing. Watched an episode of a 40 minute show during work, then streamed 2 more hours when I got home onto my tv. NFC always on. Listened to an hour's worth of music using bluetooth while driving. Texted all day. Mix of wifi and mobile, I'd say 50/50. wifi while at work and streaming to my tv, and the rest on mobile. About an hour on phonecall.

Do not have Package Disabler Pro.

I disabled the following applications through application settings:

1. Amazon

2. Android Pay

3. Device Unlock

4. Facebook(I use the browser instead)

5. Google play movies & tv

6. Lookout

7. S Health

8. S Voice App

9. Samsung Gear

10. Samsung Milk Music

11. Samsung+

12. Tmobile Name ID

13. Tmobile TV

After installing the new Samsung update (MMB29M.G935VVRU2APB5) I have about the same battery life. Right now i am only getting 22 hr battery life. Before any OTA updates i could make 1 days and 8 hour battery life. Samsung or Verizon definitely screw up something in one of these updates to kill my battery life. I am not sure why a 3600 mAh battery can't last more than a day of use?

I have backed up and restored my whole device to try and fix my battery life after the first OTA update (MMB29M.G935VVRU2APB4). After the update i went ahead and installed all of my apps while restoring my contacts and sms. Then used my phone for a day or two which i was notified to update my phone onces more which was wifi fix. After installing the update (MMB29M.G935VVRU2APB5) yesterday hopping my battery life would go back to normal which i experienced the same battery life of 22 hrs. Reading through this forum some of you guys are experiencing wifi issue which i was one of the lucky few that did not have this issue.

Anyone else know what i can do. I really wish i could revert all these OTA updates and go back to my orginal battery life i had on day one of use.

Here is before battery screenshot of the battery life I originally had before install any OTA updates..

Here is screenshot of my battery life I am currently getting after install the Ota updates I previously mentioned.

---------------------------------------------------------------------------------------------------

So guys I checked my phone today and have been battling battery life, since I updated the first OTA update from Verizon. Now the Android system is running at 100% there is definitely something wrong here. I have looked at posts on battery life from the s7 users are getting at least 2 days worth. The S7 has 3000 mah battery and the edge has 3600 mah. What is going on here. Do you guys think my phone is defective? I am trying understand why my phone can only get through a full day. I am literally missing over 24 hours of battery life I use to have when I first received my s7 edge. Are you guys also experiencing this? Is this only happening to Verizon customers? ... My last phone was LG G2 which could easily get 24 hrs battery life, but after a OTA update I could only get 8 hrs which why I updated to the edge.

Hmm weird, i dont get the "android system" issue but in my case its the "android os" which eats up battery and possibly leaks data (hopefully im wrong with this)

Anybody knows why "android os" data sent via wifi is so high?

Appreciate the insight
[Samsung Galaxy S7 Edge Questions and Answers] waternut13134:
Mine does that as well and I think it's normal,you only had your phone off the charger for 10 minutes,that's the only thing your phone is seeing that is using a good amount of battery,give it an hour then check back you should see a few more processes and android system usage go down.
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:
Not really an issue in your case. It’s barely visible and it’s been discussed that it doesn’t affect the Exynos version. Just the Snapdragon.

However, your battery life is quite poor, I would look into seeing if anything is preventing your phone from going into deep sleep with GSAM.
[Samsung Galaxy S7 Edge Questions and Answers] bOkz:
Thanks for your input however its still somewhat odd that there's a huge data going out. Referring to the data sent via wifi...
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:
Agreed. I would do the most basic thing first a just reboot it first to see if it’s just a rogue process trying to send something. Then I would check to make sure diagnostics are turned off as that could be the data your phone is trying to send.

Other than that, it will be pretty hard to pinpoint without root.
