Is it just me or is battery life worse on nougat?
[Samsung Galaxy S7 Questions and Answers] Tekkpriest:
Did you do a factory reset after updating?

Back up your data and do it. Use the Recovery Mode (Phone off -> Hold power / Vol Up and Home Key) and wipe Cache/Factory Reset.

If possible install everything fresh and don't use backups (except for messages etc of course). Especially on an Exynos model of the S7 Nougat's battery life should roughly equal or be better than Marshmallows, Snapdragon also, but since i don`t live in the US, i can't verify, since the majority of my friends and myself use the Exynos version.

Also check your apps for wakelocks and the like. Disable/uninstall apps not needed (for example if you don`t use Samsung VR/Gear, deactivate it. It will help improving battery life).

Other than that, enjoy nougat :)
[Samsung Galaxy S7 Questions and Answers] Cusa:
I did a fresh install and battery life is horrible.
[Samsung Galaxy S7 Questions and Answers] billubakra:
I am facing this too on the exynos variant after updating to Nougat via OTA. BTW what does formatting have to do with fast discharge after update? I mean it shouldn't make any difference.
[Samsung Galaxy S7 Questions and Answers] vikasn95:
try changing mode

is it possible that you might be constantly in high performance mode?

as it increases screen resolution and backlight , might be the cause of battery drain.
[Samsung Galaxy S7 Questions and Answers] biffwitch:
I've gone up from 5 to 5.5 hours SOT on MM, to 6 to 6.5 SOT on N. Should definitely be better.

Make sure you turn off all the junk like smart stay and gesture sensor crap.
[Samsung Galaxy S7 Questions and Answers] OrenGazala:
I feel nougat battery life is better either.
[Samsung Galaxy S7 Questions and Answers] gatekpr:
My battery life is a JOKE after the upgrade (via ODIN) to Nougat. I did flash HOME_CSC to keep all my data. I've disabled all the extra settings, knocked the resolution down to 1920x1080 and made sure it's on optimized performance. I've also put every non-essential app to sleep mode. I do use my phone more than average, but I haven't gotten a whole day's battery yet. It also is back to burning 5-10% overnight night on cell standby that it wasn't doing with 6.0.1!!

I love the look and feel, but this isn't worth it for me. I use TrueCaller, so I don't need the advanced call blocking. I use Nova Launcher, so there's that. I haven't found another major advantage yet to outweigh the bogus battery life.

I'm going to wipe the whole phone and restore only text messages and see how that goes this weekend. :crying::eek:
[Samsung Galaxy S7 Questions and Answers] Vcaddy:
try reseting all app permissions by going to :

settings> applications> click on the 3 dots on top right> click reset app preferences.

now restart ur fone and enjoy the awesomness of nougat !

*please not that this trick will only benefit people who are having high android os or system drain by default ( or since the install of nougat), which could be caused by nougat new permissions conflicting MM.

Battery life idle drain had increased for me in nougat. Now get 4.5 hrs earlier never got below 5hrs sot.
[Samsung Galaxy S7 Questions and Answers] VIRGIN KLM:
WOW I just can't believe how bad battery life is on Nougat. It has similar battery life with AOSP based ROMs that are early in their development. I was hoping that either the reports are not true but not only they are true but I wish I could show everybody how bad it is. I will flash Marshmallow back and stay there until this mess gets fixed. This is seriously scary, I can't believe they released the firmware at this state. Even more I hope they will eventually bother to fix it because something tells me they won't.
[Samsung Galaxy S7 Questions and Answers] olafsand:
How bad it is for you? For me its bretty good. Today i put my phone to charge on 1% battery left. Before that i look battery usage. 49h online and 5h31min sot. I only use 4g not wifi
[Samsung Galaxy S7 Questions and Answers] VIRGIN KLM:
I have atleast 6-8% draw per hour with it being in my pocket without any radios on or doing anything at all. This is a disaster. I flashed back MM and Ithink I'm gonna stay here. TBH I didn't like the changes in Nougat. I thought I would but I didn't. There are alot of stuff that make no sense to me but having a terrible battery life on top of that it's a deal breaker.

EDIT: Oh did I mention that this draw is with PSM on? Without it it's even worse!

Also I feel that PSM on Nougat is inferior to MM. It makes no sense.

Even worse is UPSM, the MM equivalent was better.

Ugh, I just really wanted to like Nougat but I'm so dissapointed.
[Samsung Galaxy S7 Questions and Answers] sardor_x_z:
Hi, I have G930T US t mobile variant of gs7, t mobile is pushing update cant turn it off. Last time when i had PG1 update battery life was awesome! at least 2 days of normal usage, after PK1 update phone was getting hot and battery became lasting for only 1 day! It is loosing power when i am not touching the phone average 5 persent in standby. So i am hoping after nougat my 2 day happiness of battery life comes back.....
[Samsung Galaxy S7 Questions and Answers] VIRGIN KLM:
Back on MM and battery life is day and night difference. It can't be on my mind. Went for jogging for a bit over an hour with music playing and it just went 1% down.
[Samsung Galaxy S7 Questions and Answers] sardor_x_z:
G930T. Yesterday updated to Nougat, after PK1 Nougat defenately wins in battery life. Phone is not getting hot, stable battery. After update battery was 70% so i got 23 hours of normal usage calls texting facebook + AOD with 70% battery. Perfect!
[Samsung Galaxy S7 Questions and Answers] obamaforever:
I am terribly disappointed at nougat. The battery drain at MM was 1 procent during 5 hours (!!!) with some tweaks but nougat is totaly crap.

I have 2 procent every hour with nougat at standby and after I have deleted a lot of bloat.

But I have a problem. When I go back to marshmallow by flashing via ODIN I cannot hear sound during calls. Why?
[Samsung Galaxy S7 Questions and Answers] archbishopKL:
Also having battery issues since the Android OS update. My battery usage indicates 'Android System: 21%' and 'Android OS: 15%' which seems abnormally high. Have tried the 'reset app permission' solution that has been suggested and see how it goes.

This is very disappointing as I just got my S7 and had been enjoying great battery life until the Android OS update. Is there a consensus on a solution/any indication from Samsung as to a fix?

Thanks.
[Samsung Galaxy S7 Questions and Answers] gerhard_wa:
If you have battery issues try to disable Chrome and use the Samsung browser or Opera Mini or pretty much any other browser. Chrome is a battery waster of gargantuan proportions under Nougat for me. Only using another browser wasn't enough for me, I had to disable it in the settings.
[Samsung Galaxy S7 Questions and Answers] archbishopKL:
Thanks. Actually Chrome hasn't been giving me problems. It seems that the 'reset app permissions' trick worked (OS and System items in battery usage window are back down to 2-4% which is as it was).

Thanks for help.

Battery life is amazing on nougat at 1080 mode.
[Samsung Galaxy S7 Questions and Answers] peachpuff:
When it comes to battery life, xda provides plenty of laughter. Its horrible, its great, its amazing, it sucks, omg i can't use the phone...
[Samsung Galaxy S7 Questions and Answers] *Detection*:
About the same, maybe slightly better here
[Samsung Galaxy S7 Questions and Answers] RiTCHiE007:
i use to get 1 maybe 2 days of use but now almost 3 and i have the exynos version.
[Samsung Galaxy S7 Questions and Answers] *Detection*:
In many reviews and tests, lowering the resolution has shown to have little to no impact on battery life, I'd be interested to see you switch back to 1440p native resolution and test for a few days / week
[Samsung Galaxy S7 Questions and Answers] RiTCHiE007:
It should have little impact but nougat in general eats less battery so that's why I'm getting nearly 3 days of use with 4+ hours sot
[Samsung Galaxy S7 Questions and Answers] *Detection*:
Why do you run it at 1080 then?

I bought my S7 for the 1440p screen along with other things, I'm not about to purposely downgrade it

1080 doesn't look as sharp as 1440 either, IMO it's a pointless gimmick that reduces the quality of the display, and considering a phone is 99% about the display, I want native 1440p
[Samsung Galaxy S7 Questions and Answers] RiTCHiE007:
Well to eacht its own but i dont even see the quality of the downgrade and i have it set so that video etc still gets the full resolution just the homescreen and some app dont. But ill take the extra battery life any day tho.

[Samsung Galaxy S7 Questions and Answers] lndulgence:
I don't know bout your units but my S7 flat exynos' battery life proved otherwise after upgrading to 7.0. With some debloating and turning off the services I don't really use, I can safely say that the battery life became rock solid.
[Samsung Galaxy S7 Questions and Answers] takerhbk:
Life is same without aod but worse with aod on. And worse in 3g.
[Samsung Galaxy S7 Questions and Answers] Djuganight:
My phone is now charging and I'm happy to say that I unplugged it from charging yesterday morning (22/03 @ 8am).

Lasted up to today, 22/03 @ 3:25pm, so with just 3% remaining I put it to charge.

It will be my second charging cicle since I have the phone and I must say that is holding very nice actually.

For example yesterday evening it was with 26% and this morning ate 8am add 25%., so just 1% overnight, WOW.

I have not made many calls these couple of days but I did a few with and without bluetooth handsfree car system, text messages, facebook, 1 hour to 1:30hours of youtube, emails, foruns, web browsing, installing and uninstalling apps, etc.

With all this more than 24 hours of battery life.

When I have the wi-fi connected the battery drains and I trust if wasn't for this, I would made 2 or 3 days with a full charge.

Here are some printscreens so that you have an idea.

I only installed Gsam after a few hours of unplugging the charger so not fully accurate.

I will try to make a video with some "battery saving" things I have made in my phone.
[Samsung Galaxy S7 Questions and Answers] mausbock:
I also had trouble with nougat. I used BetterBatteryStats from this forum to identify the partial wake locks and then disabled some services and apps beside other bloatware already disabled using Package Disabler pro.

[Samsung Galaxy S7 Questions and Answers] thundastruck:
Personally, I haven't noticed a difference in battery life from MM to N. Flashed through Odin and never once factory reset. I always upgrade the firmware as soon as new ones arrives. My advice is to constantly check for new updates and upgrade as soon as possible. The first Nougat firmware was horrible, the one after that was better, etc.
[Samsung Galaxy S7 Questions and Answers] mausbock:
SOT: 1 h 34 m

But before the device had no deep sleep and max runtime of 30 hours at same usage scenario.
[Samsung Galaxy S7 Questions and Answers] Djuganight:
What is your usage scenario of you don't mind asking?

I'm sure you don't use data nor wifi and with only 7% SOT is because you use your telephone mostly as a paper weight lolol
[Samsung Galaxy S7 Questions and Answers] mausbock:
Sorry, that's not right. It was low usage but I used the phone.

At night the phone was in flight mode, ok. But at day 4G and Wifi was always enabled. I had 40 min phone calls, 3 hours listening MP3 and 1.5 hours screen on time with reading and writing Emails, SMS and Tapatalk.
[Samsung Galaxy S7 Questions and Answers] billubakra:
Is your device rooted? If not then have you disabled few apps or done anything to lower the battery's consumption?
[Samsung Galaxy S7 Questions and Answers] loris100:
Just bought an used s7 edge ( 2 months old phone), coming from an s6 edge and man what a difference...got 8 hours SOT and 24 hours on battery...i cant be happier then this and it was the main reason i swapped the s6 for an s7....other then that they are pretty much similar and barely a sidegrade from the s6 to s7.
[Samsung Galaxy S7 Questions and Answers] Djuganight:
My device is not rooted and I'm not planning to root it, at least for the time being.

Yes, I have been doing a lot, mainly testing options to see what helps reducing the power consuption.

What I have noticed is that no matter what I do, what really drains the battery is turn wi-fi on. This is it and nothing else!!!!

I turn the wi-fi on and battery simply, starts to bye bye.

To be fair didn't even test it thouroughly with data connection to see how it behaves.

So, if I would use the phone just for calls, text messages and photos, I trust I would have battery for 2, 3 or even 4 days, depending on the number of calls. But this is a smartphone and even when I'm sitting in front of a computer I rather see some things directly in the phone. It's like smoking. It's an addiction already :)

But what have I done exactly, well:

- I start using the dark pearl wallpaper from Themes app. Some say that use a black wallpaper saves battery specially on amoled screens. Don't know if its true.

- Some claim that we should reduce the screen brightness to 30% and also turn off automatic brightness. This is a stupidity as you will not be able to see your screen in the daylight. So I had this feature off but quickly I realised that should be on.

- With the app Package Disabler Pro I have disabled lots of bloatware. Particularly the Gear VR crap was consuming a lot of battery. So what I don't use I have disabled. I don't even understand why the brand load the devices with such crap and also don't allow us to safely uninstall.

- Turned off Led Indicator

- turned off Video Improvment (only thing that does is increase the brightenss to the maximum. Even hurts your eyes after few minutes so can't understand what improvment is this after all)

- Scree res set to 1920x1080

- AOD only from 08:30 to 22:00 (why AOD when we are sleeping???)

- Settings > Advanced Functions (mine is in portuguese, but should be then 5th option) the majority of option is set to Off

Etc etc etc. Small things really, nothing that important.

The big issue here is the wi-fi, period!

Anything you need to know, ask ;)

---------- Post added at 04:49 PM ---------- Previous post was at 04:46 PM ----------

8 hours SOT????

Well, you just use the phone for the basics then (call, text messages and not much more...)

Other than that is virtually impossible on a phone with such specs. If you start using internet and apps using connections you would have to have a 4000mah battery at least to achieve such a result and eventhough, wouldn't achieve that easily. You are dreamer eheheh

BTW, you will help others by showing proofs of what you are saying. For example, Please share some battery stats because now I'm curious.

Not many posts before there was another member that was claiming the phone last 4 days, which did, but what he forget to mention is that he uses the phone as a paper weight lolololol

Did you try BetterBatteryStats from this forum? Using this app You can find out the apps / services responsible for the wake locks.
[Samsung Galaxy S7 Questions and Answers] Djuganight:
Better batery stats works well with Root.

Without root is more compex to achieve a good monitoring and even then you won't unlock all features.

I'm using AccuBattery Pro, which is very good indeed and also has an option of dark theme specifically for amoled screens.

Its really nice, but nice might not be as good or as eficient. Give it a try drop your opinnion ;)

Gladly I don't have any problem with wakelocks. My phones sleeps like a baby losing only 1% to 2% overnight.

On standby the battery hardly drops a percent.

My only complain is in fact the battery drain that is caused by wi-fi. I rarely use data so don't know if data drain the battery the same way as wi-fi does, but I believe it might do also...
[Samsung Galaxy S7 Questions and Answers] takerhbk:
Have no root.

Now even gsm batter doesn't work properly after nougat.
[Samsung Galaxy S7 Questions and Answers] mausbock:
Ok you say, You don't have wake locks at night without Wifi. Do You have wake locks if You enable Wifi?

Second suggestion: I had trouble in past with my S5 mini using mobile data. The device did not disconnect any of it's server connections and that also resulted in battery drain. I was able to see this with the app Network Connections from Anti Spy Mobile in PlayStore. Can You try this app and have a look on the processes in its current connections tab? If You see many connections You can easily close the apps by using 'close all' from recent apps (left soft key). Then the number of processes with connections should be less than before.

Here is an example:

1. I use PlayStore, so it has many data connections visible in Network Connections app.

2. Then I close PlayStore from recent apps view and go back to Network Connectios app. After automatic refresh I don't see any established connections from PlayStore.

The more established connections the device has, the more battery drain You will have.

On my S7 I had many connections from Google Backup Transport and Gear VR Shell last week. After disabling them I have no more high battery drain.

---------- Post added at 09:08 PM ---------- Previous post was at 09:03 PM ----------

Simply use the following app and enable the required features like descibed in the thread post #4.

You don't need root. I also don't have root.

BetterBatteryStats is for analyzing wake locks, the Network Connections app is for analyzing draining open network connections using 4G or Wifi. So I suggest the second app for analyzing Your problem.

- I start using the dark pearl wallpaper from Themes app. Some say that use a black wallpaper saves battery specially on amoled screens. Don't know if its true. Already using a dark wallpaper dear.

- Some claim that we should reduce the screen brightness to 30% and also turn off automatic brightness. This is a stupidity as you will not be able to see your screen in the daylight. So I had this feature off but quickly I realised that should be on. I have some issues with my eyes so the brightness is already the lowest.

I don't even understand why the brand load the devices with such crap and also don't allow us to safely uninstall. I have disabled facebook, wa, chrome, instagram via the app manager. What's the difference if we disable them via PDP?

- Turned off Led Indicator Very important for me, can't turn it off.

- turned off Video Improvment (only thing that does is increase the brightenss to the maximum. Even hurts your eyes after few minutes so can't understand what improvment is this after all) Will turn it off.

- Scree res set to 1920x1080 Mine is the same I guess, from where to check it just to be sure?

- AOD only from 08:30 to 22:00 (why AOD when we are sleeping???) Don't use it. Also it is disabled under battery saver.

- Settings > Advanced Functions (mine is in portuguese, but should be then 5th option) the majority of option is set to Off Did not get this point.
