[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
My last observations about 'Running Processes' and 'Processes in Cache':

'Running Processes'

- After installing Oculus and Gear VR stuff (got the thing yesterday) Peoples Edge and Briefing feeds (clip board) got re-enabled (incl. notifications) and Oculus got added to the list. I was able to stop all notifications but the main process Briefing-feeds (Clip board) I could not stop from running. Not in 'running processes' and not in the App manager (in setting > applications).

'Processes in Cache' [tab more in top right corner of 'running processes']

- The Cache contains processes and services from apps that I haven't used yet [e.g. Maps, Facebook, Weather] and which are also not disabled. Removing these processes from Cache does not work unless you disable the app in App manager/Pack. Disable. But, Weather is a system apps and does not allow to be disabled thru App manager so I left it as is (something is holding me back from installing Package Disable). Facebook & Maps I intend to use in any foreseeable future.

So to conclude, processes kan be viewed in better detail in 'Running Processes' and 'Processes in Cache' to determine what service is running under what process. Stuff can be killed or disabled but you need a more aggressive App Manager to actually do so without root.

I installed Greenify last night before bed. I Greenified a few running apps but got a lot of FCs so I deGrenified them and only enabled aggressive doze mode. Look at the difference!

sorry to be a newb, great article I've been experiencing not so great battery life also on my s7 edge.. could you walk me thru how to do all of these things. Sorry to be a newb some i know how to and others i just want to make sure I'm doing the right thing? thanks
[Samsung Galaxy S7 Edge Questions and Answers] robstunner:
Im about to return my Samdung today because of this terrible battery life. I dont understand how there is such a massive difference here.

AOD: off

Google Location: off

Google Now: Off

Location: High Accuracy

Debloat: All att and some samsung (not package disabler)

Social media: G+ and Twitter only, notifications and sync disabled.

NO gaming

Samsung pay enabled

100% of my apps I turn off notifications and all that, ZERO apps.

How the hell does someone get 4hrs with 50% left after 13 hours while im at 38 MINUTES at 85%?
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
What a drag.

Semi-Random questions you probably don't want to ask since you already sound very frustrated, and have declared your intent to return the device.

- which phone network are you on (as in country and provider)?

- which specific device variant are you using (SM-G935???) - if you don't know you can find it printed on the back in small text

- how did you setup your phone (copy from previous or clean setup)?

- did you allow Google to restore from previous backup of apps installed, or manually install one by one?

- what is the system reporting as consuming the power?

- have you used a tool like gsam to help target power consumption more?

- do you have an SD card installed or not, if installed did you enable encryption on the SD card?

There's (at least) two other large discussion threads with lots of free advice ... some help some don't. They cover a LOT of ground though, so wading through them and their setup tuning advice can take a while. My intuition tells me you don't have the remaining patience for it, and that's okay.

It's crap that it is so easy to configure the phone to destroy battery life, and that it can be triggered that way with very little end user activity, but that's apparently the reality.

It is however very possible to get very decent battery life from the device.

We've seen enough anecdotal posts from different regions in the world and multiple network providers (even in same regions) to lead me to believe it is possible.

It's just too dang easy to go the other way too.

I also side with the belief that there are definite programming issues which too easily can be triggered to destroy battery endurance. Some on Google's part, some not.
[Samsung Galaxy S7 Edge Questions and Answers] belloni:
What does enabling encryption on the SD card do? I have one but have not done anything to it.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Other than the obvious? I don't know for sure.

But, I highly doubt that the SD card would have full-drive-encryption hardware built in which Andriod could leverage, so I will continue to assume that any read or write to the SD would at minimum be more processing intensive and thus use more power. Since I typically listen to music off my SD card for 4-6 hours a day this is a factor, to me.

Personally, I had first enabled it on the SD card I have in my device and a week later had the card filesystem "implode" - came up corrupted and not fixable.

I reformatted it and reinstalled WITHOUT allowing encryption of the SD card and it's been fine for going on 2 weeks now. {shrug}

Note that I never pull the SD card out, my intent is to leave it there until it is exhausted, I absolutely MUST replace it with a larger card (current card is 128Gb), or I upgrade to a new device. I mostly manage card content using an FTP server on my phone (staging content via Downloads), otherwise via USB connection and MTP transfer directly from my PC.

I know there isn't a lot of screen on time here but I think this showcases the batteries standby ability.

All syncs are on including 3 emails, location and Bluetooth are on as well. Nothing is gimped here. Also, I had the Edge Clock on for 7 hours overnight.

This is inline with what I'm seeing.
[Samsung Galaxy S7 Edge Questions and Answers] TIGGAH:
I wanted to drop in my 2cents here. I was having terrible battery life like lots of people here. I was about to return my phone when I decided to stop at the Samsung kiosk in Best Buy. I figured they might be able to help. They ended up reflashing my phone. It doesn't wipe out data it just reinstalls all the system files.

After they did that my battery is much better. Not perfect but better. I only lose 1-2% at night and can make it all day with fairly heavy usage. My iPhone 6+ still has a way better battery but hopefully with some updates the S7 will be on par with it.

edit.. wow I need to update my sig... It's been a while since I've been here.
[Samsung Galaxy S7 Edge Questions and Answers] vecchiae:
I followed the instructions on the first post of this thread but I am still surprised that the WIFI and phone radio shown on the main screen of GSM Battery Monitor are showing 14h 17m as active, the same amount the phone has been off charger. The GSM Battery Monitor "Other" chart also shows WIFI on all the time, a continuous line (BTW, the Keep WIFI during sleep is set as Never, and the phone has been on my desk near the router). Unfortunately I do not have the ability to attach screenshots, I suppose because I am a new member on the forum, I do not see any 'attach files' icon.

Thus, is it normal that WIFI would be reported as always on, or do I need to research what it is keeping it active?
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
This is from my other phone which i dont use much. I reset it and configured wifi to be only on while charging but gsam reports wifi was on the entire time. I dont see that in yours
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
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. Unfortunately, the Fingerprint app starts up again everytime I use my fingerprint to login, for obvious reasons.

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
When I woke up to go to work, I turned WiFi off. Had I not it would have reported staying awake the whole time. Even though I have WIFI set to turn off unless it's charging it will still report as running. Even when it's reporting to run I still don't notice an quicker discharge rate.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
That's funny you say that because I thought this for days which is why I didn't enable it for 3 days. When I enabled it I didn't see any difference in battery life.
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
According to GSAM, my WiFi stays on all the time even though set to Never during sleep. Here's my screen shot with GSAM. On a good note, I only lost 2% overnight while sleeping.

Tomorrow I'll manually set WiFi off prior to bed and see what GSAM records.
[Samsung Galaxy S7 Edge Questions and Answers] Monkey Slut:
I have Wifi set to Never during sleep as well, and I have the same problem as You - the apps shows that Wifi is active all the time
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
There's likely something keeping it awake, or awakening it. Location checking. "Nearby device" detection. Other things are possible, but I believe these are known to turn on wifi (temporarily) to do their work. If there's an issue with them shutting it back down I guess it could come up as using power constantly.

I had been manually turning it off when appropriate but thanks to a hint from someone else on the forum I am using the "My Places" Edge Panel to automatically enable/disable WiFi (basically, I only have WiFi at home so the default otherwise is off, and I have it explicitly off both "at work" (based on location) and "in the car" (based on bluetooth connection to my car).
[Samsung Galaxy S7 Edge Questions and Answers] exconvictriddick:
Do what I've always done with new phones. Setup the new phone, sync your google stuff (I disable some like google music, photo and drive) and don't download any apps for the first cycle (3 at most). Then slowly add the apps you mostly use.

I found 2 app weren't playing nice on my phone so I stopped using it. That might help you.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I was worried about this same issue in the beginning but it seemed like every time my WiFi percentage was up, my Phone Radio was down. If I kept WiFi turned off then my WiFi would be way down but the phone radio would be way up in regards to percentages.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Something is using data in the background that you are not aware of or intending?

For example, background data usage I don't want (even with basically everything notification-wise turned off) is one of the reasons I refuse to use the Facebook app or messenger. They abused the privilege of being on my phone so don't get to play any more (at least until 2017 when I will revisit to see if their behavior improved).

Did anyone install the new Samsung wifi fix update yet if so please report back if this update fixed the battery life and Wifi (MMB29M.G935VVRU2APB5). I am on verizon Samsung S7 Edge and my battery life lasted almost two days easily, but after i installed the first OTA update my battery life was split into half (12hr or so). I followed OP's instructions in this post sadly backup and resetting my phone did not fix the battery life which is little disappointing. I am hoping this new update fixes my battery life. Anyone know how to disable OTA updates?

Thanks!

As of right now i have OTA update waiting to be install on my phone (MMB29M.G935VVRU2APB5) that fixes the Wifi issue. I am little scared to install this, since the first OTA update (MMB29M.G935VVRS2APB4) killed my battery life.

Mine does, about 1 Mb per day unwanted data usage by:

- Google Account manager,

- Samsung Push Service,

- OS Service,

- Facebook (this is new today, I now disabled the whole App),

- Google Play Services

- and something I would call 'upgraded amenities' if I had to translate it to English (bottom of screenshot).

My Data is on but i disabled all background syncing for these apps and set every settings of these apps to not sync, send or retrieve data. They sometimes wake up the device from doze but mostly the data is send after DnD ends in the morning and just before it starts in the evening. My battery does not seem to suffer much from it, the drain is always between 2% and 4% per night.
[Samsung Galaxy S7 Edge Questions and Answers] darkmetal:
What application are you using to display that? Also my post has been edited to show the update build numbers. I have tried to disable everything yes. I am thinking it is probably a unstable android app that is killing my battery life.

Click on held awake in gsam. It'll show deep sleep and doze information.
[Samsung Galaxy S7 Edge Questions and Answers] Willyman:
Mine only dozes when I leave it alone for a long time and even then quite sporadically. Is this normal? How quickly should the phone go in "doze" mode after turning off the screen?
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
Without any modifications through apps the doze mode is supposed to kick in after the phone has not moved for about an hour. So if the phone is in your pocket and you're walking or doing something else then it won't kick in.

If you use an app like Greenify, it has an aggressive doze mode that puts the phone into doze mode within minutes rather than an hour.

i have found that disabling chrome and using the samsung browser has dropped my android system percentage by about 10-15%
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
Can anyone confirm that this works?
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
With both my regular S7 and the Edge I have found the opposite to be true ( tests by reviewers also confirm this). The Samsung browser sucks up more battery than Chrome while browsing .
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
chrome was giving me bad android system drain, this is just my experience
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
If Chrome does the same on Android as it does on windows (opening multiple processes for fast internet experience) than this doesn't surprise me. Chrome sucks the battery of my windows 10 tablet dry in a matter of a few hours.

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.

It did the same for me as I used it for Facebook and had notifications enabled. I installed the Samsung browser, but it also was at the top of my list instead of Chrome, so it doesn't seem to make much difference. I went back to Chrome for the syncing.
[Samsung Galaxy S7 Edge Questions and Answers] Hellspire:
Quick question for everyone. Have you guys tried turning wifi completely off? I'm doing it this morning and the phone is running so much better for battery stand by time. I think something with the wifi is what is causing the phone to be kept awake.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
I have my phone setup to turn off the wifi automatically most of the time actually.

I use the Edge Panel "My Places" to turn ON the WiFi when I am at home (determined by location), OFF when in my car (determined by bluetooth connection to my car being live), OFF when solo bicycling (determined by bluetooth connection to my headphone receiver which I tend to listen to music over). And the default state is off (for Out and About).

Since I have very few places where i use wifi, this works for me. if I had wifi at work I'd have it on there to save mobile data/radio usage (which would also probably be lower power consumption).
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
What app do you use to shut off WiFi automatically?
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
That might be true on the sd820 model but definitely not on the international one!
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
Ill upload screenshots tomorrow when i have a proper day for battery testing. Personally my battery has been much better after I disabled chrome, and im not getting the high Samsung browser battery usage that you all are talking about.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
The "My Places" Edge Panel, it's part of the base system on the GS7E.

Enable "My Places" panel and then setup accordingly. IIRC by default it has "Out and About", "At Work", and "At Home".

You can use the latter two,and any custom "places" you create to set a small variety of settings, and also define a few apps to have on the panel unique to each place.

I think of that last bit as augmenting the "apps" and "shortcuts" panel with location specific apps (like I have the Kodi Kore app at home for controlling the Kodi media player on our Mac Mini).

[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
I think this is true. I, too, have disabled chrome and used the samsung browser. I think I did notice Android Systems going down. It would be around 30 or so, but after disabling chrome it went down below 20 or something (forgive me if I'm not giving accurate measurements). I prefer the Samsung Browser anyways, it's much faster than Chrome

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.

You're not alone. I have a co-worker who gets 2-3 days on standby and a little usage. If I keep my edge on standby and use it here and there it will barely get to a days worth
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
Standby is surprisingly decent (3 days with 3 hours SOT and 10% left) but I haven't been able to get over 5 hrs 30~ minutes SOT total.

At the most, I can maybe squeeze 6 hours SOT. That's with or without packages disabled, after factory reset and cache wipe, all diagnostics turned off, background data turned off on most apps, most usage being feedly, reddit sync and chrome using night theme for 2 of those, brightness at like 10%, wifi all day, location disabled, google now hotword disabled, AOD disabled, email sync disabled. If I enable most of these and use my phone like regular, I get 4 hours SOT. I just got a 4G LTE CellSpot so hopefully that improves it a bit as that's the only factory I can imagine. This is with SD820. If I could hit 7 hours SOT I could finally be at ease though I'd like to be able to hit 6 hours SOT consistently without having to disable and turn down everything.
