My Android System has not dropped from the top since updating. Would someone please let me know the proper way to clean the cache? Thank you!
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
My battery isn't good. Help.

(I'm just teasing and trying to lighten things up in here. Jeez guys, we're all trying to figure this out. Sounds like a fix is on its way . . . thank goodness).

Sent from my VZW S7 edge
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:
Two ways:

1) Go to Settings > Storage > Cache

This will prompt you to confirm you want to clear the cache.

2) Turn off your phone. After it has completely shut off, hold down Power + Volume Down + Home Button. When the screen turns on, you should be able to let go of the power button, but hold on to Volume Down + Home until you get to a new screen with a menu. Using your volume rocker, select “Clear Cache” and use the power button to confirm selection. After it completes, reboot the phone from the menu.

The 2nd option is regarded as the cleaner method.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
I very much appreciate your help. When I try to use the second method, I'm brought to a screen that says "Warning... A custom OS can cause critical problems in phone and installed applications." Volume up: Continue, Volume down: Cancel

I assume this is not the correct screen. Just to confirm, I held down Volume Down+Power+Home Button to arrive at this screen.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Should be volume up
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Ok, thanks. Will I lose all of the settings for my apps if I do this?
[Samsung Galaxy S7 Edge Questions and Answers] takethebox:
Way better today. Pretty happy so far. High Android System but not sure its actually affecting battery life.

How many days have you had the phone? This is day 2 for me and I'm currently at 24% with 2hrs38min SOT, 14h37min total time on battery. Hoping to get A LOT more SOT
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
It was way better for me today, too (This is day 4 for me). The phone was in my pocket for 2-3 hours, and stayed at 72% the entire time. It "optimized" a bunch of apps for battery usage this morning, because they hadn't been used in 3 days. Perhaps that's all it needed. Either way, I'm happy that it's moving in the right direction.
[Samsung Galaxy S7 Edge Questions and Answers] msage:
I've been curious about that "optimization" feature. Glad to hear it seems to be making a difference! Looking forward to my apps being optimized
[Samsung Galaxy S7 Edge Questions and Answers] takethebox:
This was day 4. Seems to be getting better at managing apps. System is flying.

I am getting an easy 6 hours of screen on time even with the android system being on top. I am impressed but always wonder what it could be if we got that under control.
[Samsung Galaxy S7 Edge Questions and Answers] fernando sor:
It seems even with the battery reading android system as the largest consumer of power you guys are still getting 5 to 6 hours SOT. Not sure what the issue is then.
[Samsung Galaxy S7 Edge Questions and Answers] Pilz:
I'm only managing 2-3hours SOT at best with the same set up as my 6P that gets 4-6hrs SOT
[Samsung Galaxy S7 Edge Questions and Answers] jackdforme:
Just a thought. Since android system is the core of the phone, it just might be that everything you run is more power efficient now and because of that you are seeing the system take a larger percentage than you are used to seeing. Larger percentage doesn't mean larger battery drain. Just possibly more time spent at idle.
[Samsung Galaxy S7 Edge Questions and Answers] cepheid46e2:
The problem is very simply that people are looking at a lump some of app usage, kernel usage and android systems together and freaking out. If people used a proper parser like GSAM this thread wouldn't exist.
[Samsung Galaxy S7 Edge Questions and Answers] Xileforce:
Thats surprising. I'm averaging pretty close to 11% an hour of sot +/- 2% assuming I don't play 3d games.

---------- Post added at 11:40 AM ---------- Previous post was at 11:38 AM ----------

Pretty sure there is some truth to this, as if you check the breakdown in androids battery stats it shows services from qcom among other things.

This could also have some effect, but screen should always be the biggest draw(assuming you used the screen) and considering the screen isn't any more efficient this year than last year's screen(according to displaymate) it should still be the top drainer unless you let it sit idle for many hours.
[Samsung Galaxy S7 Edge Questions and Answers] Pilz:
That's what it is not playing any games. The only game I have on my phone is Alto which I haven't even opened on the S7E yet. I'm not sure why its draining so much, but I did also disable more things to see if that would help
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
How come the exynos version don`t have this problem? that should also be on-top aswell but it isen`t :confused:
[Samsung Galaxy S7 Edge Questions and Answers] cepheid46e2:
There is no problem. Exynoss likely separates the data differently. This is what happens sometimes when coding for different chipsets. The problem lies in everyone's expectations that the phones will be exactly the same.

I don't know why you think they should be the same.
[Samsung Galaxy S7 Edge Questions and Answers] ranova:
I think the s7 goes into Doze mode very rarely. I installed greenify and enabled aggressive doze mode and turned on notifications to let me know when and how long the phone was in doze mode. So far, the past week, I've only gotten ONE notification of such and it was only for ~3 minutes. My battery has been very subpar compared to previous phones...
[Samsung Galaxy S7 Edge Questions and Answers] zathus:
That's kind of were I'm at. It very well could be that everything is so well optimized that's just not using enough power to make sense. We're all so used to seeing the screen as the number one consumption of power. And it could be that they did such a good job with the screen that it just doesn't use that much therefore moving it down the list making other things become more obvious in their consumption. Nonetheless I'm sure there's some optimization some Devs can come up with the true even further improve this
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
this should also be precent in the exynos model but it`s not, so this is out of the question.
[Samsung Galaxy S7 Edge Questions and Answers] FazeRN:
As a power user, I initially get a regular case but toward the end of my phone's life cycle, I always end up with a battery case, irregardless of whatever it is. Maybe I should just go straight for a battery case this time.
[Samsung Galaxy S7 Edge Questions and Answers] zathus:
OK, but is the exynos getting way better battery life? Serious question. I havnt looked.
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
iv only seen 2 battery tests on the exynos but it seems a little better, the screen is on top on those units with 6h SOT over almost 3 days, will get my exynos this week so ill be posting some battery life later.

I think the tmobile update just changed the packages it includes as Android system while calculating the usage. I just upgraded to the latest build and didn't recharge to 100%.

I see android system is 2nd with 20% right after installing the update. Another thing I noticed was the battery usage maH is lower. It was in the 800's before install and now it's around 400
[Samsung Galaxy S7 Edge Questions and Answers] Winpang:
Only T mobile update up to this moment ? Any news for HK version?
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Exactly what I expected. I've had a hunch that this was more of a reporting issue that a drain issue. Looks though like maybe a little optimization was done. Hope to get the update on AT&T soon!
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
I believe this to be the case as well. Seeing as how I get fantastic numbers with Android System being high. There are just a lot of other problems in this thread that I am seeing that are unrelated. Awake time, poor signal, needing FDR, etc.
[Samsung Galaxy S7 Edge Questions and Answers] bOkz:
Hey guys is this good? I disabled some of the google bloatware. Light usage. Wifi on(if wifi is available else mobile data) no bt, nfc, screen brightness 25%, all reporting off.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
It's okay. I wouldn't say it's good. Get rid of Clean Master. It hurts more than it helps.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
You have too many different screenshots but the one I see for GSAm stats is not very good. You have almost an hour SOT for 33% (which would make only 3h SOT, and held awake is 5 hours over 12 hours which is very bad.

Uninstall Clean Master as soon as possible.
[Samsung Galaxy S7 Edge Questions and Answers] bOkz:
Thanks. Ive already uninstalled clean master. Hopefully there's an update coming.
[Samsung Galaxy S7 Edge Questions and Answers] jc83:
Whoever suggested to fully charge battery and test again was spot on. After tmobile update had high 20s to low 30s android system %, now down to very low teens. 4 hour SOT at 50% battery so far.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Edge or no?
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
Don't know what happened, after tmobile update I got great SOT. But then yesterday I got my gear vr, played for it a bit and my phone has been held awake the entire 23 hours off the charger, which was right when I started playing with gear vr. I had really high play services drain, some bull**** went down yesterday.
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:
Hopefully now that root is on the horizon, we can get more details about what exactly is draining battery on our phones.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Can anyone comment on their thoughts on my battery? It isnt bad but still not trending with great SOT. This is 41 min SOT and 32 min voice calls. This is T-Mo S7 (non edge). I have about 100 packages disabled.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I'm gonna go ahead and assume that you used package disabler and used the debloat feature?
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I used package disabler pro, used the debloat feature and then added back some things I use (gear vr, samsung app store things). I then removed a couple other like some of the qualcomm trackers.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Go in, undo the debloat that you did with package Disabler, and uninstall that app. It's garbage and it is possible that it trips Knox. The debloat feature actually harms your battery (I'm not gonna explain why as I have already covered this topic at least 3 times in this thread) and disable them one by one in the application manager in your settings. Then charge to 100% and clear cache a minimum of three times via recovery.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I've seen your explanation and, while I'm not saying it is wrong, do you have any evidence to suggest that? Plenty of people are using PDP with no issues. Also, are you implying my battery is not good? Is there a master list of stuff that can be disabled natively?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
In my experience PDP hurts more than it helps. Unless you know exactly what you're disabling and how it effects the system then I'd stay away from it. 98% of those packages don't even run processes until you open the app anyway. If you want proof just go into the Developer Options and look at the running processes.
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
I think it won't hurt to use it, I have some OCD with my and like to keep it as clean as possible even just freeze it. However, I try to not freeze the app that may constantly communicate with system.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Yes, I do have evidence, however it is in the build.prop and since I am more than likely not going to be rooting my device I will not be able to show you, so you can either take my word for it and do as I said or you can ignore my suggestion and continue to get subpar battery life.
[Samsung Galaxy S7 Edge Questions and Answers] Shuthefrontdoor:
Maybe it's your poor cell signal? It shouldn't be at top of your list IMO my cell standby is only 3%
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I have full signal. Definitely not poor. What is your actual mah on cell standby?

My doze is not kicking on at all. How'd you get yours working?
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Quick note: I have been studying/coding/designing/troubleshooting Android for over 6 years now, starting from a moto backflip and owning at least one phone from damn near every big manufacturer available in the US. From this point going forward in this thread if I give you advice and you respond with a rebuttal or question my logic I am simply going to delete the comment and you can get the info elsewhere. I don't have the time nor the patience to spoon-feed everyone that comes into this forum, and quite frankly, I'm tired of seeing the same question being asked time over time. There is a search function built into this forum, use it.

Edit: I feel like I should clarify that when I say question my logic I mean if I give an explanation and someone replies "well, how do you know that that is what's really going on?" 9/10 times my initial reaction is going to be "because i have already dealt with this 5 f***ing times elsewhere and I tracked it down."
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
+Ghstudent any idea what might be up with my doze?

That's not the same thing. Scroll up. That's using package Disabler which some are saying hurts more than helps. I'm asking natively

I think there is a need to address some of the arrogant behind this post. 6 years of coding does not show that everything you said it's right. If you went to college or ever write a paper to prove something. You need quote where is come from even it's from the paper you wrote three years ago. You can totally throw a link of your old answer. I assume that much easier than he try to dig from thousands of post. I don't get it, so many people in the forum keep such arrogant just because they know something. If you choice to answer a question then be responsible to your answer. Only 6 years of coding, you already think people cannot questioning your authority? How about thousands of engineering working for google still make mistake. He may know plenty of other knowledge that you have no clue about. I don't think when you ask someone question that you don't know about, the answer you want to get is go f...find the answer I already post it several times. That's such irresponsible reply. If you don't want to solve the problem, leave it, someone else will answer it with much better manner. You can only make things worse, and there are many members who has better expertise but still keep low key in this forum.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
This what you're looking for?
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
Natively you can disable any app you don't want to if they give you an option which I think is very limited. I don't think that improve battery or drain battery though.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I could come back with some big long message, but instead I'm just gonna say this: if you don't want my information, don't use it. I promise you I couldn't give any less of a damn what you or anyone else in this thread thinks of me. I like helping people because that's who i am, but I don't like having to explain myself over and over.

[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Yes I'm aware that you can disable any app with the option. That's the point. There are over 200 possible apps so I was hoping someone has a list
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
Hmmm if you click into each app you will see most of system app cannot be disable. I have the t-mobile version so may not has as many bloatware as verizon version. The points, you can scroll through the app list. Choice the app you don't like and see if system allow you to disable it. If you don't understand what that app is for, then you probably won't able to disable it anyway. Like verizon message app, verizon navigation app, the main purpose really just to disable those app that you find annoying to showing on the app draw. Also, you can just directly go to app draw hold the app you don't want to and go into detail to disable it. As long as it doesn't show in the app draw you probably won't bothered by that app.
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
Being totally new to Samsung phones, can anyone tell me what the app called KNOX actually does? I know Knox is related to phone security, and it's also something that can tell Samsung whether you've rooted and/or otherwise tampered with the phone (for warranty purposes).

The reason why I ask is that I'm getting the super high Android OS battery drain, and my phone isn't lasting beyond 14 hours. It looks like the app called KNOX is using 16-20% battery, according to the Application Manager. Would it be safe to disable this with Package Disabler? (So far, I've downloaded the app, but I've been trying to disable unnecessary apps only through the application manager and not through Package Disabler. But Knox is obviously not an app that's meant to be disabled, according to Samsung.)
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
Highly suggest not to disable that app...I never tried it, it will effect samsung and various of stuff.
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
I'm willing to share my XML but I've disabled quite a bit of packages just so you know.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
This is a common misconception. There is no way to see WHICH system package is consuming resources. They all show the same thing.

Not what I'm asking for... The posters above are claiming package disabler pro is causing more problems than not. I was looking for a list of things that can be natively disabled.
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
Sorry for the misunderstanding. Well, if it means anything I've been running with 136 disabled packages without any issues whatsoever.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I happen to agree with your premise. If you scroll up you'll see some saying it makes battery worse. It's worth a shot so I just re installed everything and removed pdp
[Samsung Galaxy S7 Edge Questions and Answers] JosepHFJ:
What's the average battery drain you guys have in an 1hr? While using the phone.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I would highly advise you not to disable Knox, it is a security program. Think of it like anti virus on meth and steroids. Disabling this would probably make Samsung pay, the Sammy app store, and other apps not function properly/at all. But if you do it, be sure and come back what happened. [emoji16]

WeatherBug, messenger, and white pages are more than likely your main culprits, with the main one being messenger. I never install messenger because it constantly searches in the background for new messages. Use chrome and just go to Facebook instead. Weather bug is a waste, just use "okay Google, what's the weather supposed to be like [today, tomorrow, Sunday, tonight, this week, etc.]" Or "okay Google, is it supposed to rain today/tonight?" Try it out, Google has stepped it's game up with weather reporting. And white pages.... I don't have an alternative for them, I just pick up the phone and if it is a telemarketer then I just tell them I'm under 18 (I'm not, but it's illegal for them to call minors in the States) or press 0 to get removed from most call lists. Now, go back to the same place in your dev options, open the menu in the top right, and click show cached processes and screenshot that.

I've been running with no package Disabler pro for an hour now. I know it isn't a long term test but there is nothing magical here. I'm at 20 minutes sot and 92%. That's a trend of 4 hours, pretty bad.
[Samsung Galaxy S7 Edge Questions and Answers] jgodfrey82:
Just FYI, I've been following this thread daily for a month and I've used PDP minimally and am about to ditch it as battery seems much better with update and other suggestions but I did have the knox services disabled and noticed no difference, pay still worked, fingerprint etc.. I did notice when I disabled Qualcomm.location that the trusted places stopped working. I keep missing being able to really test SOT as I often need a full battery for evening activities and end up plugging in around 40% but I think I'm up to 6hours with moderate use all day. If I really download heavily or stream to chromecast, use wifi, it drops dramatically.

I was always under the impression wifi on would save battery life by dozing the cellular connection but I think battery is better leaving wifi off for this device?

Thanks everyone for the input and ideas!
