[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I am a huge advocate for setting up new phones as "New Device" rather than copying information from an old phone.

I would recommend doing a factory reset and then setting up the phone fresh.
[Samsung Galaxy S7 Edge Questions and Answers] EDubs11:
I am using package disabler. Even when I had it off I was using a ton of battery while the screen was off. This is the best battery life I have had in a phone in quite some time, but I am getting frustrated that the phone loses so much power while the screen is off. It is taking forever to get into deep sleep and, subsequently taking forever to get into doze.

I have a feeling the culprit may be the WiFi, but I have tried leaving it off the whole day and nothing changed. Here are my GSAM stats from this charge, so far.
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
My battery life has improved it seems. I just installed the latest update so that's a big factor I'm sure. But i also did several factory resets in a row and I'm only installing essential apps for now. I went from discharging 10%/30 minutes to 10%/40-45 minutes. We'll see how it manages once i install my other apps, but battery optimization hasn't kicked in yet too (the auto sleeping apps after 3 days feature). At least now i feel like my device is capable of getting same SOT as others, I'll try and get as much usage as i can today for screen proof. The update for tmo s7 edge sd820 also puts screen on top, though Android system is still pretty close and went back on top at one point. We'll see how this continues. If i can actually install my apps and enable some features, turn settings up and keep over 6 hours SOT I'll begin to love this phone.

I still have something keeping the device awake but standby time was great before, I was able to hit 3 days with 3 hours SOT and 10% remaining so hopefully that stays the same.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Alas, without root, is can be very challenging to find what is keeping the wifi active.

If you've turned WiFi off manually, and successfully configured all background reporting/etc/nearby-device-scanning/etc off, then it should remain off.

It is, alas, easy to accidentally turn it on, indirectly.

Things like the camera asking you to opt-in for putting location on pics will also change the Location settings to be GPS+Bluetoot+WiFi, which indirectly will cause dramatically higher power use by wifi. ;^(

I choose to believe that some of the other automatic background helper stuff (text-2-voice updates, reporting to Google and Samsung, nearby device scanning, location scanning, who know what background process added by the telecom providers, and potentially others, can all contribute to this.

I also believe but have no useful evidence that some of the existing infrastructure (wifi 'stack' ... bluetooth 'stack' ... media sharing component ... whatever *may* be more power consuming than a previous Android edition. {shrug} In some ways that is a drag but in other ways at least I'm only paying the power price for elements I'm asking for.
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
Turn Wifi off when not using it
[Samsung Galaxy S7 Edge Questions and Answers] Monkey Slut:
My wifi is on all the time too. Its a bug I think.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
With you having turned it off?
[Samsung Galaxy S7 Edge Questions and Answers] Monkey Slut:
Yes. I tried both off and turned on only while charging , and in both Gsam showed wifi activity all the time. It was like 20 % of battery usage on Gsam
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
To me that speaks of one of the (few, but not huge-many) background processes which CAN be phoning home and activating wifi without actually changnig the setting.

The OP of this thread has some great pointers for that, but IIRC things like the location settings and nearby-device scanning come immediately to mind.

I would guess that Edge Panel "My Locations" may also trigger it depending upon how you have specific location setup configured. I use that and use either GPS location or Bluetooth connection for location determination.

I think the theory has been advanced but not proven conclusively that any automatic background reporting/updating may also trigger the wifi.

Not necessarily an easy one to diagnose and unwire, alas.
[Samsung Galaxy S7 Edge Questions and Answers] liwei8759:
Think that's a bug in GSAM. There is a fix to that somewhere in the forums that I read the other day, just forgot which thread now... Sorry mate
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Pay no mind to the WiFi numbers on GSAM. I have noticed that when using WiFi the battery doesn't really drain faster or slower compared to mobile data. Also, if you're on WiFi most of the day, you will see that percentage up but the phone radio percentage down.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Well I can happily report it looks like this method was really "temporary".

Just to let those of you know who aren't on T-Mobile there is a light at the end of the tunnel. The update T-Mobile just pushed out today fixed the Android System battery drain. So far in 7 hours Android System is reporting 0% of the battery used.

I still have all diagnostic reporting turned off but I have been running the phone with no packages disabled. Before this update I had turned off the T-Mobile apk packages because they were running in the background but that also is no longer running.

Hopefully those of you who are on other networks get the update soon because it fixed more than just the Android System battery drain. The update also fixed screen sensitivity issues and toned down the haptic feedback. My palm resting against the edge of the display no longer registers as a touch nor does it cause the screen to go unresponsive. The phone just generally feels more responsive and I'm no longer getting lag in some games. It almost feels like the update has killed all of the unneeded background processes/services.

I was thinking about checking out the HTC 10 in a couple weeks but now I think I'm sticking with this phone.

Tonight I will leave the phone off of the charger and use it all day tomorrow so I can post some screen shots for you guys. Hopefully things stay the way they're running now.

Here in Australia, we don't seem to have the problem of Android OS drain, BUT my Screen drains the most, how do you guys keep it down?

I have Edge feeds and lighting off and brightness to a bearable minimum, I'm also using Adaptive display and dark background.
[Samsung Galaxy S7 Edge Questions and Answers] cuezaireekaa:
If you use the phone while the screen is on, its gonna be at top in most cases. That's a good thing. Its always been at the top for all of us until this bug on s7 with android system, but its back to being at top the way its supposed to be.. Its not an issue unless you've not turned on the display much at all and it still reads at the top. But also that just means that your battery is great if screen is on top and you've barely used it.

[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
I am on Verizon and we are also on PB5. Battery life is horrendous. TMO is pushing out build number ending in PC8 that has fixed the battery drain problem on their SD820 variants. Now they love the Phone. International users have had it a while and PC9 has been spotted in China. Good time are coming cause the performance sucks on PB5.
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
Any inkling of when this will be available to Verizon users? I am not sure if I should exchange the phone or not. I'm still within my 14 day window.
[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
Keep it, phone should be awesome once it is optimized. Unless, you wanna root. I kinda regret buying such a locked down phone. Past my 14 days so I am stuck with it. Gear VR makes up for that a bit.
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
Same here, it's such a huge adjustment for me, coming from Nexus and Moto phones. I'm not a huge tinkerer but I am used to being able to troubleshoot issues with things like BBS, and being so blind and unable to fix it is frankly extremely frustrating!
[Samsung Galaxy S7 Edge Questions and Answers] darkmetal:
I posted on the forums before install both Verizon OTA updates (B4 & B5) explaning to you guys I was experiencing battery drainage issue. This is no longer the case. I went into app manger and disabled all the apps that were installed with my phone (Verizon and other misc apps I don't need) after disabling these apps my battery life went back to normal. Depending on the day I can get a day and 6 hrs roughly..I'd recommend if you are having battery life problems on the s7 - edge factory reset,

reinstall apps,

only update apps you need wait to update until they are more stable on Android 6.0

disable any apps you don't need in app manger within android 6.0

turn on auto brightness seems I get better battery life with that enabled.

I did all that and I'm getting at best four hours of screen on time
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Turning off the Google and Samsung diagnostics along with a few other tweaks on top of the new update from Tmobile has turned this phone into a beast.

There isn't another phone on this planet this thin that can get this kind of battery life.

The following screen shots are from today. My usage today has been exactly what a normal person would use a smartphone for. I've browsed Facebook, browsed the Internet, looked at a few different forums through Tapatalk and streamed 2 hours worth of podcast over my cars Bluetooth.

I am on pace for 8 hours of SOT and nearly 2 days with a single charge. The SOT could be even higher if I went without streaming over Bluetooth. I could never pull this off with my iPhone 6S+

Best of all Android System drain is no longer at the top of the list.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Would you please let me know how to turn off the Google diagnostics?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Settings - Privacy and Safety - Turn off Diagnostic Reporting

Settings - Lock Screen and Security - Other Security Settings - Turn off Send Security Reports.

The first one is for Google and the second in is for Samsung.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Great, thank you!
[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
That is the sort of performance I expected from this phone. Meanwhile, Samsung are telling me that 100% -> 79% overnight drain on a stock, out-of-the-box S7 Edge with all of the settings mentioned in this thread set to disabled 'can happen'. I regret buying this thing.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
That's exactly the type of battery drain I got overnight during my first couple days with this phone. Something is definitely wrong if it's losing that much power in standby. 100%-79% overnight is not right.
[Samsung Galaxy S7 Edge Questions and Answers] MArtyChubbs:
What carrier do you have? What is the last two characters of your build number?
[Samsung Galaxy S7 Edge Questions and Answers] Onyok:
After upgrading to PC8, my phone's been off the charger for a good 1d 9h 40m with a SOT of 4h 46m 29s! There's quite a significant boost! Awesome!

[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
Is it the OTA update that sorted it for you?

Would you mind disclosing what build number and kernel version you are running please? Under Settings - About device - Software info

Thanks much.

---------- Post added at 01:47 AM ---------- Previous post was at 01:40 AM ----------

How do you guys 'upgrade to PC8' etc? Do you have to go into your local Samsung store? I've tried to see if there are any updates available by going to Settings - About device and then checking for a software update but there aren't any available. I assume you updated via OTA? Is the update a US only thing or can other carriers around the world choose to push it out too? Is it a Snapdragon variant only update? If so, I'm screwed even if I somehow manage to get hold of the update files.

I'm currently running MMB29K.G935FXXU1APB6. I feel like I'm so close to resolving this thing but just can't identify the final thing I need to do.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
What sorted it out for me was what I went over in my original post in this thread. The update just made it that much better.

The update was only pushed by T-mobile US at this point. Snapdragon version.

Build = PC8

Kernel = 3.18.20-7620454
[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
Thanks, got it. Judging by what others who also have updated to it have written here, that PC8 update really sealed the deal with regards to battery life. It's a shame I can't get it. Stuck with an expensive paperweight here. Sigh.
[Samsung Galaxy S7 Edge Questions and Answers] ionutdicu:
I don't think the PC8 sealed that much battery drain problem; the only significant improvement you get by deactivating AOD, although it was one of the main reasons I bought S7 edge.

They really should improve thea AOD feature (timer for stopping at night and not by replacing with night clock, dimmer light etc)
[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
I agree, ionutdicu, that basic features shouldn't cause such issues. However, I've tried everything outlined by jrwingate6 in his original post and I'm not getting anything close to decent SOT. Never mind the amazing SOT that he's getting, I can't even manage half that!
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I turned of the AOD since day one so I don't know what the battery life is like with it enabled. It got on my nerves more than it helped.

Prior to PC8 I was getting close to 7 hours SOT with a little over 24 hours use. After PC8 I am getting close to 9 hours SOT with close to 2 days use.

The steps I outlined in the original post lowered my Android System battery usage to around 20%, down from 35%. It also lowered the Android OS battery usage by a small percentage however they were both still always at the top of the list when looking at the battery stats.

Now after PC8 they are no longer at the top of the list and usually end up somewhere in the middle. The percentage Android System uses now is below 10% and Android OS is below 5%.

These numbers are without a single package disabled.
[Samsung Galaxy S7 Edge Questions and Answers] Namyep:
Do you have notifications on for Facebook or turned off?

I disabled Facebook with tons of other bloatware with Package Disabler Pro and just used fb on browser but after seeing this picture I thought I'd give it a shot.

This is how usage looks for me so far. I feel that it shows a little bit wrong as I listen to a lot of music (can't be 3%), switching around with 3.5mm headset and sometimes using my PowerBeats2 Bluetooth headset.

Edit: as you can see first picture shows 57%, second shows 56% and by the time I was done posting this I'm at 55%. Is this normal? I'm on my second charge cycle so phone is still new if it is worth knowing to anyone
[Samsung Galaxy S7 Edge Questions and Answers] jpcloudsurf:
Eh I realized it wasn't done right
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Looks like it's been off the charger for nearly 24 hours and your above 50% with 3 hours SOT. Looks decent to me.

Thanks very much jrwingate6. I was actually hoping you could post the section under Settings-Battery-Battery Usage, then tap on Android OS and Android System. Really appreciate all the help. Samsung should be paying you consultancy fees or something.

Just one question about your point 5:

5. Turn off auto update in the pay store.

I assume I need to open the app and there's an option to switch off auto-update somewhere?

Just trying to replicate your steps exactly.

[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
As for turning off Play auto updates...

You will still receive notifications for apps that have been updated. But you will have to open Play Store and choose to update each app (or select Update All).

Personally, I've seen enough issues with this sheep-like acceptance of updates which, sadly, turned out to be buggy, that I prefer to have absolute and granular control over anything being updated. Some might call me paranoid. LOL. But I like to know what I'm installing before I install it.

[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
Thanks TheWu-Wei. Seems I read it incorrectly. I thought jrwingate6 meant the Samsung Pay app lol. My mistake. Yes, I've already turned off Play Store auto updates.

Just waiting on jrwingate6's Android OS and System stay awake times. Mine clearly show that my phone isn't sleeping and therefore isn't dozing.

[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
I agree. Are there any others you'd suggest disabling that haven't been mentioned?
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
Well, any app repository will usually offer the auto update option. I always set them to manual. Play Store, Amazon, Samsung, F-Droid, BlackBerry Manager, etc. I also agree with disabling background reports wherever possible. But realistically, these functions are not the source of this excessive drain. Not in my opinion, at least.

[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
Again, I agree. Definitely something else causing the drain but best to have updates off and subjectively apply them of your own volition.
[Samsung Galaxy S7 Edge Questions and Answers] Machine_Head:
Is it possible that the Android Device Manager is causing the drain?
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
For me, it was the bluetooth sucking up power. I disabled: "Settings - Nearby device scanning"

I also disabled the useless Edge feeds as I read that it keeps the touchscreen on. Who does this magic rubbing to see one line of non-useful information?

I think the battery life could be better, but coming form Galaxy S6, this is so much better. 4.5 hours screen on time, and it easily lasts a full day.

I have a LG G Watch, so I keep bluetooth on all times. Wifi too. And location stuff, and all that too. I did disable software updates, but don't know if that has any effect at all.

[Samsung Galaxy S7 Edge Questions and Answers] Veeshun:
I've been searching for the past hour. Where do I find the option to disable the Samsung background reporting? I have the Verizon version and I do not see the option under Privacy and emergency.

I noticed Knox accounted for 24% of my battery usage yesterday, what can I do about this? I also noticed my Android OS stay awake lists 7 hours 8 minutes, what is going on with my phone?
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
No secrets, I just keep just about everything disabled until I need it. Background sync, auto sync, diagnostics and reporting stuff are all OFF, power save ON, Wifi and BT OFF until needed, etc. Basically all steps which OP described from step 3 onward, step 1 and 2 I never did cause my phone came out of the box flawless, performance wise.
[Samsung Galaxy S7 Edge Questions and Answers] ookubanjo:
Well this part it seems no one can figure out. Mine is the same. In other words, my uptime and my stay awake time match. Really insane.

Good to know, thanks. But won't disabling sync mean you don't get emails immediately etc? That's something I can't do unfortunately.
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
Probably yes, i'm on a laptop all day for work so I only put auto sync on if i'm in a wifi-less place and those places are scarce in my persnickety country ;)
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
Okay guys, I'm gonna share my experience. At first my battery life was good, but then I got the first official update (March) and my battery life went to crap for some reason and I came to this topic...

What I get now: e.g., today, 4h18min screen time of very active use and 44% left. So if we extrapolate - it's ~ 8 hours SoT. White-theme (I hate dark themes), dark wallpaper (but I like dark wallpapers!), Chrome + WhatsApp + Tapatalk + Navigation (NOT! Google Maps), AOD off, WiFi on, BT off, GPS on, Sync on, 4G on. Brightness is always at 40-50% level, automatic.

This is how I greatly improved the battery life (about x2 better than before):

1) turned all bloatware that I could with the native app manager

2) with Package Disabler I killed Smart Manager, com.samsung.android.slinkcloud, Google Maps, Microsoft Word (these 4 apps had active processes for some reason and were draining battery without me using any of them) and some bloatware that I did not need.

Chrome is very high on battery drain. With heavy Chrome browsing expect about 5.5-6.0 SoT as a good result. Without Chrome, but some heavy WhatsApp and so on expect 7-8 hours SoT. With heavy movie viewing expect 8h+ of SoT. If you go further and use dark theme - you can do better. But this is more than enough for me.

And yeah - almost no battery drain when not using the phone. During the weekend I had about 48h on battery, 1h SoT, 70% battery. When the April update comes (the one that some people got already) I will turn everything back on and update (and report here). If the battery life is bad again, I will turn off everything as I did this time.
