I started my Galaxy S6 920I battery issues a long time ago and couldn't find any help without rooting or tripping knox, so here's how I went back to a normal state. I want to share my experience with you guys and maybe help someone who's desperate like me.
UPDATE: 5.1.1 India OTA came 2 days ago and my problem is solved now. No more deep sleep isues.
device: 920I on Stock 5.1.1 India (G920IDVU2COF8), Brazil on VIVO network.
problem: "Android OS" process show up eating almost 50% of my battery, even on idle. I couldn't even get through the day. If I went to sleep and just left my phone alone with wifi, data, gps off and all apps closed, I would wake up with a dead phone.
conditions: I didn't want to void Knox since I think I can still use my warranty for something, even though Samsung offers a pretty lame service here in Brazil.
background: I've read basically everything regarding this subject and nothing seemed to work for me. Wiping cache, factory resetting, nothing.
method:
STEP 1: ERASING IT ALL
My phone came with stock 5.0.2 and I updated to 5.1.1 (Trinidad and Tobago) via Odin hoping it would solve my problems. It didn't, at all.
I decided to do a full wipe and flash 5.1.1 India just to see if the problem was relying on the ROM itself
When my phone started, I added my google account, normal setup, and then started disabling the useless Samsung features like motion gestures and Wifi always scanning
I DID NOT download any app from the play store, I decided to get them back gradually in order to try to find the problem.
I started disabling every app I though it was safe to to so. Here's the list: ANTT Radio Service, ANT + Plugins Service, Brefing, Dictionary, Drive, Dropbox, Facebook, Galaxy Apps, Galaxy Apps Widget, Google Play Books, Google Play Games, Google Play Movies & TV, Google Play Newsstand, Google +, Hancom Office Viewer, Instagram, Live Weather, Memo, Messages, Messenger, OneDrive, OneNote, Peel Smart Remote, S Beam, S Health, S Planner, S Voice, Samsung Galaxy, Samsung Push Service, Skype, Hangouts
I Kept basically Whatsapp, Hangouts, Play Music, Gmail and updated them through Play Store
Downloaded Google Keyboard since I hate the samsung one
Then I went to sleep with 15% battery. Woke up with 15% battery. Good job.
STEP 2: PUTTING INTO TEST
I woke up and charged the phone until 100%. Got our of home, wifi and data off.
I commuted for 60 minutes while listening to cached Play Music songs. Made some calls. Turned data on, used some whatsapp. Battery still on 94% at the end. Seemed ok.
When I arrived at work, I decided to enable instagram and Hangouts back and check on it again. My battery was on 92%.
1 hour later, my battery was 80% and "Android OS" was at the top of draining list again. Nightmare.
Uninstalled instagram. 1 hour later I had a drop of 3% without touching the phone. Android OS still on the top.
Uninstalled Hangouts and enabled default samsung Messages app. Answered some whatsapp chats and left the phone sleeping, didn't touch it. 1 hour later, battery dropped by 2% with Android OS on top.
Restarted and wiped cache. Things went back to normal.
NEXT STEPS
It seems like there's some serious bug with the apps, but somehow there's s System bug that needs to be sweeped with a cache wiping. That's the continuous process I need to be doing on regular basis.
I wonder, would it be that simple? A simple app making continuous requests to Android System and putting it on top of the draining list, hogging all of my battery on idle for nothing?
Anyone had the same problem?
Most likely a defective battery. Return your S6 back to Samsung telling them of your extensive tests as supporting evidence and request for a warranty repair/replacement.

Does anyone have a list of apps safe to disable on stock S6 Android 5.0.2? I've found some on the internet and on the forum, but nothing specifically for Samsung/TouchWiz and nothing for Android 5.
Thanks
I disabled loads when I first got my S6. After having problems when trying to call people, the first time I press call it went straight back to dialer, I factory reset and declined to disable anything barring the google apps I don't want, and my phone has the same RAM and battery life as it did when I disabled everything.
I would recommend leaving it stock as it doesn't affect battery or performance or RAM.
I disabled email, music, and internet without any issues. There might be a couple more but I don't remember.
I disabled these because I use gmail, Google music, and chrome, respectively.
Hi! I just bought the note 5 and everything's been great. I just started having a leaky battery though. It started after I restored my apps with an app from the Play store. Additionally, I downloaded previous problem apps like Skype. I wanted to confirm that restoring apps instead of downloading them still causes battery problems with the battery and if Skype is still a problem. Additionally, I had modified the sync settings of my social media apps, news feed, etc but I saw no significant change.
I just uninstalled all of my apps, drained the battery all the way, and charged it up fully. I do still notice a rapid decline though. I wanted to upload a pic but it said it was an invalid file Any comments are greatly appreciated and if you need more info, just ask, thanks!
Hello.
For several months, on my Galaxy S8 +, I suffered slowdowns on several levels:
update badges indicating the number of unread messages is only long after having passed a message or other read / unread
check for system updates with a result return after several minutes, see tens of minutes
calls of certain applications on click of the notification (google Play, system update ...) does not display the application immediately
installing apps via Google Play is long after download, 100% OK download but install after several mintues
This only happens from my home, so may be related to geolocation.
I tried lots of actions but nothing works, among other things erase all the data and caches of several Google applications:
Google locks framework
Google play store
Goolge
Google Play services for instant apps
Google Play Services
Badge Provider
etc ...
I also tried other solutions like:
Reset the S8 +
Delete and re create my Google Account
Delete Samsung account
Disable Smart Lock function
Switch to airplane mode, correct the problem for updating badges but obviously, can not check Gogle Play updates or System because no network
Disable WiFi only, problem persists
Disable GPS only, problem persists
Disable mobile data only, problem persists
Disable the IP V6 of my Box (BBox)
Call Google and Samsung without success
The only 2 actions that have a positive result are:
To uninstall all Google updates. It worked fine initially but unfortunately recently, after the update is done, in beta mode or not, the problem appears again.
Disable Bluetooth only, and the magic, after a few minutes, it works again and it is in time. Concern, more access to connected objects
For information, I use a Samsung Gear S3 Frontier connected watch with apk Samsung Gear and Samsung Health.
I did not push the tests beyond due to lack of time. For example, uninstalling some applications.
This post is a bit long, but it is the result of several months of investigation.
While navigating, on various forums, I note that I am not an isolated case and that several people are concerned of loan or by far. I tried to do a synthesizer.
Would you already know of such a problem and if so, do you have a solution, tracks, suggestions?
In advance, thank you to all those who will take some of their time to help me solve this problem.
Hello, I own a Galaxy S6 G920F, I bought it new 2 yeas ago.
Everything started like 2 months ago, I let it charge overnight and next day when I unpluged it, the red led was on even when I unpluged it and the screen wasn't turning on. Ok, I force restarted it and every was good. After that I get crashes from youtube, google play services, olx.ro (like ebay for romania), zedge.
When I want to add an account on youtube I get Google Play Services has crashed. If I want to watch a video on youtube app, it plays like 2-4 minutes and after I get Youtube has stopped working. If I wanna add a google account in settings or playstore, same Google Play Services has stopped working error.
In games is not crashing, in facebook, instagram, browser, waze and other apps is working just fine, i don't get it
Once a day (or often) it just freezes completly and autorestart after 1 minute.
I tried many custom roms like Ultimate nougat s8 rom, miui port, lineageos and all of them crashed apps and some of them even restarting after 2-3 minutes of usage
I just wanna know if I can fix this or is my motherboard bad or something. I was planning to buy a motherboard for like 50 euros and swap it but maybe you guys can help me fix it :good:
Sorry for my bad english and ty for your time!
disconnect all the cables from the mother board and reconnect them
I haven't had any sleep data since July except for some incorrect nap readings for full night's sleep. The watch shows I have slept but the phone app doesn't show anything. I have the latest version and I don't want to do a factory reset. Any suggestions?
Same here. I tried with factory reset, reinstalling Health app, updating HMS, uninstalling HMS and installing Wear OS, uninstalling both, unlinking Google Fit, linking the watch to two other phones, erasing all cloud data associated to the account.
The watch itself shows sleep data. Recently it started syncing no data at all, except hearthbeats.
Sent it to Huawei support, they returned it as "cannot reproduce".
Same here. Huawei Health version 10.1.1610. Device Huawei Watch GT 2e version 1.0.3.20. Still having problem sync data at least once every week.
Most of the days they work, some day failed. Not so consistent and reliable communication between device & gsm.
