So per the suggestions earlier, I brought back all the bloat and removed pdp. With pdp heavily debloating on my last cycle, I was off the charger for 13 hours, had 40 minutes of SOT and 30 minutes of voice calls and I was at 75% roughly. Right now, I'm off the charger for a little over 2 hours with 50 minutes sot and no voice calls and I'm at 82%. Not really seeing the magic of putting the bloat back on the phone. Here is my current usage. Android system is 140mah. I'm open to ideas but right now I've never been able to get to more than 4 hours sot

If you're looking for a nice full feature weather app that doesn't east battery or run in the background then check out 1 Weather. It also has the nicest looking interface out of all the weather apps.

Has anyone noticed a difference using or not using greenify? Just wondering if there is any reason it could be hurting things?
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I can't read that list, resolution is too low
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
Better?
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I recommend disabling internet through the system and using chrome, that's one that is sticking out a lot to me.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
That was my fault. I pulled that info with a ton of stuff open.
[Samsung Galaxy S7 Edge Questions and Answers] @soka:
My findings,

Main culprit for excessive battery drain is :

Google Play Services

com.samsung.imagecompress

com.andriod.bluetooth

com.android.vending

i am now using amplify & greenify to prevent these wakelocks, and hibernate Google Play Services.

Will share my full SOT time once battery is down to under 10%

Right now i am on 34% with 4h 18m SOT.
[Samsung Galaxy S7 Edge Questions and Answers] NemesisHunter:
Measuring today's battery, I'm at 5.6%/hour, drained 89% over a 16hr period.

According to GSAM, my most active tasks are:

SOT: 4:06 at 41% (753mAh)

Wifi Active: 16hr at 16%

I have Location fully enabled, AOD Off, Bluetooth On, Wifi On, Data On, Sync On, Auto Medium Brightness.

Phone spends 95% of its time on WiFi connection.

It seems to be a high drain to me, and this is after a factory reset (PDP has not been used).

However, I also play a lot of Clash Royale (which used up around 2h18m of CPU foreground time)

Might this be what results in my low SOT?
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
How do you know these are the drains without root
[Samsung Galaxy S7 Edge Questions and Answers] optimummind:
After taking the March security update from Sprint (PB5), my battery life is still very unusual. I went from getting 6 to 7 hrs of SOT with my usage habits to under 5 hrs.

Like many affected people, my number 1 battery drain source is Android System, even after disabling bloat with PDP and using Aggressive Doze with Greenify.

But what's really weird is when my drainage is the most severe. I take the phone off the charger at 6am. I use my phone to read some news with my morning coffee and when I put it inside my pocket to get ready for work, I'm usually at 96%.

I use my phone again to do some reading before I head in to work and battery is at 93 or 94%.

While working, my phone is just in my pocket.

I come out for a break around 10:30am and my battery is drained to 75%! Before the update, battery would be at 90 or 91%.

And this weird drain only happens in the morning. Not when I'm out to lunch and not during the rest of my shift.

If I turn off GPS before heading in to work in the morning, then it's back to normal.

Any guesses?
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Even though the latest update has helped, there is no reason for Android system and Android OS to be using 800mah over a day
[Samsung Galaxy S7 Edge Questions and Answers] @soka:
Cause i am rooted, only way to run amplify and greenify is with xposed. :confused:
[Samsung Galaxy S7 Edge Questions and Answers] givmedew:
So I'm coming from an iPhone 6P and have not had Android since Verizon launched the iPhone.

I've successfully converted many of my customers over to Galaxy S7 and S7 Edge. Told plenty of them that the edge battery is only 20% larger so not a deal breaker so the ones that didn't need the bigger screen got the normal s7 well ALL of them came back because they think the battery is crap... Had to explain to them what I learned.

The iPhone battery isn't anything special... But if your not using your iPhone and it's at 80% and you leave it at home and come back 12 hours later it's at like 67-73% if no one was blowing you phone up!

I leave my Samsung Galaxy S7 Edge alone for 4 hours and I might come back to 80% after waking up going to work and not using my phone at all by the time I am out of work I'm at 50-60%.

This is unacceptable! Battery saver mode barely changed this except for the ultra battery saver mode.

The bottom line is this I went from a phone that wasn't that cool and didn't do nearly as much and had me locked out of a ton of stuff but the battery would last 2.5-3 days and the messaging was amazing (iMessage and continuity) to a phone that won't last me the entire day. I'm at 50% and I charged it to 100% less than 12 hours ago! I can deal with the lack of iMessage and since I have sprint and they do something special with Google voice (my sprint number is also a fully fledged Google voice number) I basically have continuity anyways since I can sit and text or call from anything using my main number and not having to deal with a secondary Google voice number.

Anyways I love this phone and my only beef is the battery!

That's it!!!

Fix the battery I'm good! Till then I'm not converting any more people from iPhone to Samsung.

Also Motorola does not seem to have this issue as badly! I mean it doesn't last as long as an iPhone 6 Plus on standby but the Turbo 2 and Maxx 2 are good phones!
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Thats what I thought... Most of the battery issues are on the SD device which isnt rootable thats why I asked
[Samsung Galaxy S7 Edge Questions and Answers] @soka:
My apologies, assumed it was for both variants.

Really hoping you guys get root soon. :fingers-crossed:
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Ok so I'm pretty sure I know that our battery issues are related to something in the OS hitting the internet a lot. In a couple of these threads, around 2 weeks ago I showed that my Android System/OS under data usage mobile and wifi were using a lot of data and way more than they should have been. Last night, after not getting great battery life by adding back the bloat and removing disabler pro, i turned on the regular battery saver just to see what would happen. One of the things it does is restricts background data. Now, my battery life is the best ive ever seen on any device.

12h on battery

5h 28m sot (within this is a couple hours of netflix streaming)

I still have 35% left

The first 20% though with 4 hours off the charger and 1 hour sot were without the battery saver turned on.

This to me seems to indicate something in the background (mail sync, backup or something) is constantly chewing our battery.
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
OK, so I didn't disable Knox, but I did use Package Disabler to disable Help and a couple other apps that also exhibited what appeared to be similarly high battery use. I will let everyone know if it helps.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
You're right. That is totally unacceptable. I would download GSAM if you haven't already and see if your phone is failing to go into Deep Sleep or Doze. I can leave my S7 Edge sit for 9 hours and only lose 3-4%.

Mind you I am on T-Mobile and just got the first major update for the US version. If timing holds true, Verizon should be getting the update in a few weeks. You would think as much as you pay for a Verizon mobile plan, they would be the first to get updates out.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Can anyone else try and confirm this?
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
I tried power saving mode few days ago and didn't like it. Lot of stuttering while browsing websites and buffering while steaming over lte
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Im not really experiencing this. I guess what I'm trying to figure out is if it is really a background data thing going on like i initially thought
[Samsung Galaxy S7 Edge Questions and Answers] guaneet:
You must have disabled something you shouldn't have with PDP. Try gsam battery monitor and see if your phone is being "held awake"
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
So things are going really good now. After the update (and factory reset without reinstalling a ton of my usual apps) I got 8 hours SOT and then I had insane held awake time when I got my Gear VR. So now I'm reinstalling most of my apps back and I got Greenify to disable Oculus app from being listed as running service. I noticed the Oculus app reenabled automatic updates even though I disabled that, but even with it disabled it was popping up under running services.

So now I tested my SOT and with brightness at 10% it discharged from 100-95% in 30 minutes. This was an improvement from right after the update when it was 20-25 minutes, and before the update I only got 15 minutes. So battery life has doubled since before the update. Even more exciting, I tested it on autobrightness from 95-90% and I'm at 57 minutes SOT. So lowering brightness was only a negligible difference and keeping it at auto-brightness, I could still conceivably hit 9-10 hours SOT. Also the app battery saver just kicked in once I hit 90% so there are some additional savings there. I also just enabled Smart Lock before this and it was still an improvement over last time somehow, did Greenify really help this much? I've had location on high accuracy as well.

With further testing I'm going to see how big of a hit Messenger and Screenwise take on my battery. They're installed but not logged in or set up currently and I suspect they'll take a little chunk but I'm curious how much. I'll be glad to be over with constantly keeping an eye on my battery and just being able to use my device.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
What are you referring to? Please see my post above. I'm talking about the fact that I'm getting good battery now and I believe the reason I don't get this great battery normally is some system app constantly doing something in the background which could explain the battery problems for everyone
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
In my case Google play store, Android os, whatsapp, Google photos and Google services use the most background data. BUt I get 7 hrs sot so not really worried for now. I set the power saving mode to be turned on at 20%
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Thats my point, you cannot tell what is behind android OS without root. So by goign to power saving mode, the background data is cutoff
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
Yes that's true. I would have thought by disabling diagnostic reports this will reduce but it looks like something built into android that sends data out.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Yea so here is my battery on the non edge t-mobile. Not using PDP. The magic for me seems to be power saver which kills the background data solving the issues on this device.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
You should be able to restrict background data of individual applications, WITHOUT using power saving mode, by leveraging the "Optimize battery usage" feature

On my SM-G935A it is at: Settings -> Battery -> More -> Optimize battery usage

According to my phone this restricts background data usage, implicitly similar to Power Saving mode which does it for everything.

On my device there are four apps listed which can NOT be set that way, Google Play Services, Messages Backup & Sync, Samsung Push Service, and Visual Voicemail.

I suppose I could use package disabler to turn off the middle two, but I use Visual Voicemail and don't believe it would be safe to disable Play Services. Since I don't use their stock Messaging app and have backup/sync turned off I don't see that process as being very active. I haven't noticed Samsung Push doing anything either, so again I won't waste time on that.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
1) Optimize battery usage doesnt work on Android OS/System stuff

2) Same thing as restrict mobile data

This is the issue.
[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
Why would package disabler be harmful for disabling apps? Please explain. Also, why do you need to wipe the cache 3 times. Seems like voodoo..?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Because you may disable a package that causes TouchWiz or the Android OS to keep pinging it. When it pings it and doesn't get an answer it will just keep trying to ping it.

I don't know about clearing the cache 3 times though.
[Samsung Galaxy S7 Edge Questions and Answers] guaneet:
If I remember correctly he thinks the app has too much authority, only being usable with device administrator enabled. If you disable the wrong files it causes issues like random reboots, if you know what you're freezing then it's worth it. Many people including I have used it with no issues

Wiping cache is to believed to delete short term files that the system builds up, it'll get rebuilt as you use the phone. I didn't even wipe cache/dalvik when I flashed a kernel. A reboot usually does the trick for me.

[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
PB5 is crap. It's killing my battery on Verizon... Waiting for the update TMO got...
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
This guy has been paying attention, cookie for you. And the wiping cache thing, there were rumors years ago that Android recovery wasn't the most well built recovery in the world and most developers back then advised you to wipe your cache numerous times instead of just once just to be safe. It's just what I've practiced for years and it hasn't let me down and since it only takes a few extra seconds I advise everyone to do it.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
If you disable package A, and an app that is not disabled depends upon it, or a system process depends upon it, then you can cause your device at best to have application problems, but at worst render your application or device inoperative. In-between states where "resilient" processes keep re-trying against error conditions could effect greatly increased power consumption owing to processing activity.
[Samsung Galaxy S7 Edge Questions and Answers] nyt:
After the update, my android system is lower than cell standby, and just above device idle.
[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
So, package disabler works great to disable bloat like slacker or amazon kindle and you only need to wipe the cache once. Three times if you are stuck in the past. Correct?

respect...

booyakasha!
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I still do not recommend package disabler because as someone said earlier in the forums, there is a slight possibility that it could be picked up as a hacking attempt and trip KNOX, and since I haven't read a lot into Knox and what trips it, I'm just going to play it safe and not take the risk. However, if you choose to ignore that slight possibility and use it anyways, use it to hand pick apps instead of using the debloat feature as the developers (for whatever reason) have set it up to disable a lot of packages that the system relies on, which makes the system ping for that package time and time again. And the cache thing is like I said, back around the S2 era there was a lot of rumors/stories concerning wipes not completely wiping, I actually experienced that issue myself while going back to stock one time and ever since then I have always double-triple wiped whenever I need to. There actually used to be a joke amongst users about how you don't just wipe your ass one time after using the bathroom.
[Samsung Galaxy S7 Edge Questions and Answers] JosepHFJ:
After doing a factory reset an wiping cache this are the results.

There is no question in my mind this is the root cause of these issues. It is only confirmed by my test yesterday that I mentioned about turning on power saving mode which restricts background data

are there no new ways to improve battery life on the sd820 variants?
[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
[MENTION=5465516]JosepHFJ[/MENTION] - am I missing something here? That looks like amazing battery life, 4h5m and you've only dropped 17%?! That's amazing. Unless I'm reading GSam incorrectly?

Oh, and if it makes you feel any better, I have the same luck with smartphones.

Is there anyone here who has rooted their S7E in order to be able to see what specifically behind the Android OS service is causing the drain and is willing to share their findings? My Android OS and System are also the ones causing issues. Apologies if someone has already shared this info somewhere in the preceding 88 pages. Would appreciate being pointed in the right direction if such a post exists.
[Samsung Galaxy S7 Edge Questions and Answers] JosepHFJ:
When I did the initial set up of this phone is was getting 8hrs SOT but now I'm down to 5-6, but I have to take into consideration that I'm a heavy user.
[Samsung Galaxy S7 Edge Questions and Answers] Krautmaster86:
my solution 4 high drain

http://xdaforums.com/showpost.php?p=66247134&postcount=24

The last Samsung Push Service update which comes automatically increased the standby drain by ~200%. Uninstalling means downgrade fixed that issue.
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Thanks but won't that essentially turn off the ability to get carrier updates too?
[Samsung Galaxy S7 Edge Questions and Answers] Krautmaster86:
well, it only "downgrades" to the version before that update (think it is a system app which can't be uninstalled without root). As it seems to affect other devices (eg S6) too it might be fixed from samsung soon. Therefore, i didn't notice any change in usability. It simply pops up as ready to be updated in playstore again. I'd post a link but im kinda marked as noob from XDA until i have 10 posts ^^

(worked ...)

U can clearly see when I downgraded the Samsung Push Service in Playstore. Last night (yesterday) I wondered abt a constant drain of android system, uncommon and I checked my latest updated apps.
[Samsung Galaxy S7 Edge Questions and Answers] Shaylin:
Im having the same issues with my S6 Edge Plus after MM and then a 16mb update for MM made the battery drain even worse.
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Damn. Wish it worked for me.
[Samsung Galaxy S7 Edge Questions and Answers] Krautmaster86:
did u find the Samsung Push Service in Playstore "My Apps" ? Was it updated? Can u select Uninstall? Is it available for Update after that?

I rebooted my device after a single time after i selected "uninstall" .
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Yeah I uninstalled it and have auto updates off (rebooted as well). With that said I almost have an hour of SOT already and I'm at 89%. But Android System continues to run high.
[Samsung Galaxy S7 Edge Questions and Answers] Krautmaster86:
hmmmmmmmmm okay ill install it again and compare / verify

Edit: Since when so u face that issue in general?
[Samsung Galaxy S7 Edge Questions and Answers] lazard:
would probably have better battery stats if I didn't get such crappy reception at home
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Yeah, it's been going on since I had the phone. I really even hate to complain because this is by far the best battery life I've ever had on an Android phone. Guessing once AT&T's carrier update is released, it'll be fixed just like T-Mobile customers have had. And I still have a hunch that it's more how the battery is being reported than actual drain.
[Samsung Galaxy S7 Edge Questions and Answers] optimummind:
For me on the Sprint GS7E, I had to change from GPS Only to Wifi & Data to prevent high battery drain during idle. My Android System drain dropped significantly.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
I feel so frustrated at this point. Nothing I've done seems to make any difference. I feel like I've tried every permutation of options discussed across multiple discussion boards and the best battery life I've been able to pull off is about 10-11 hours with relatively light use. I even have the latest T-mobile update installed, which made pretty much no difference. Meanwhile, my wife is able to get over 35 hours of usage with her S7 and she uses her phone way more than I do. Android System just keeps chugging along at over 60% battery usage on my phone.
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
Something is not right with your phone. I would try to exchange it.
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
"Sleep" doesn't mean screen off. It means when the phone enters deep sleep. That option won't, and isn't designed to, turn WiFi off whenever the screen is off.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
This is actually my second phone. I returned the first due to the same problem. Hence, I'm pretty sure this has to do with one of the apps I have installed or one of my settings. I just haven't been able to figure out which one.
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
I've got no problem with people complaining about their phones. But complaining that someone isn't helping you when you haven't provided any information to help them actually do that is pretty childish. "How do I make it better?" is pretty hard to answer without any information about what's wrong.

---------- Post added at 03:17 PM ---------- Previous post was at 02:56 PM ----------

https://en.wikipedia.org/wiki/Samsung_Knox

As others have stated, the battery percentages for every system app (as shown in the app manager) are the same, because the battery app only tracks at that level. So seeing 15% for Knox doesn't mean it's really using 15%, only that all system apps in total are using 15%.
[Samsung Galaxy S7 Edge Questions and Answers] Willyman:
For those worried about the battery drain coming from Android System and OS, be patient, the April update fixes it for the most part.

Before this update, Android System was always on top with 25-40% depending on how much screen time I had. Now, it's way down the list.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
What's your SOT? I'm coming to terms with the fact I won't ever get more than 4 hours SOT.
[Samsung Galaxy S7 Edge Questions and Answers] Willyman:
Typically can get just shy of 6 hours. I'm a pretty heavy user though, BT connected smartwatch, 4 push email accounts, Facebook WhatsApp etc...

If you spend more time consecutively with the display on you'll get higher SOT. What I mean is that you'll get much higher SOT during a day browsing on the couch than during a regular workday.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Yup. I can't get more than 4 regardless though
