With the latest update (DQIC) it's not heating too much anymore. Maybe it's that outside it's not 35°C hot or it's the lego-mounted fan I use when I charge the phone, anyway I see the temperature with Gsam battery monitor and now it doesn't get hotter than 33 degrees. S7's software for sure is still the old touchwiz we know (it's not hardware fault for sure) so we have to hope in Oreo (or UX 8.5 maybe).. as usual we have to wait :silly:

SoT has dropped significantly the second half of this year, S7 flat were averaging 5-6 hours SoT with MM and early Nougat, S7E were averaging 7-8 hours SoT

Samsung have killed battery life by about 20% with all updates since around May iirc
[Samsung Galaxy S7 Real Life Review] fracarol:
Just when I bought the phone hahaha

I think the only way to fix that will be Oreo unfortunately
[Samsung Galaxy S7 Real Life Review] fracarol:
Yesterday evening I got the October security patches.I updated then fully charged, deleted cache and this is the result.

WiFi always on (but offline mode during night), always on display on, mid battery saver (background data off, speed limiter on, HD resolution) and all the apps in the screenshots. Nothing disabled in Adhell. Autobrightness on.

Not that bad, even updated and installed some apps

S7 flat exynos
[Samsung Galaxy S7 Real Life Review] *Detection*:
That's more like it, I just got that update today so will see if it has fixed battery life

That's about what I used to get for SoT
[Samsung Galaxy S7 Real Life Review] fracarol:
I have the feeling that it could be better, sometimes I noticed some 1% randomly going away but who knows
[Samsung Galaxy S7 Real Life Review] thevibas:
I,m still on 1st August Security patch, After disabling Wi-Fi Scan for location service averagely i get about 4:50 to 5:20 hours of sot, it doesn't matter wifi/data is on or not you'll get only 10-15 minutes of difference. If i use continuously i get more 20-30 minutes of sot like 5:40 hours which is kinda weired. and i've notice i lose battery so fast from 100-85% like lightning and when it drops down 30% it gives me very goo sot, with only 30% i can use 2+ of sot on normal usage like YouTube, Instagram, Facebook through UC Browser.

Wifi/Data on all the time

GPS Off, NFC Off, AOD Off , Bluetooth Off, Auto Sync Off.

Let me know if October Security Patch update is worth to update or not. Or avoid by turning auto update via Wi-Fi Off.

[Samsung Galaxy S7 Real Life Review] *Detection*:
5-6 hours was the average SoT people got during MM and early Nougat, some got a little more some less but mostly 5-6 hours, you can get more by leaving the screen on without using the phone much etc but for normal usage that's about normal
[Samsung Galaxy S7 Real Life Review] DeeStyles:
It was almost unthinkable a month ago. My phone is the Galaxy S7 Edge model SM-G935W8 in Canada. Recently rooted and flashed latest Superman ROM. I remove all the system apps I do not use.

-Modified Pixel Launcher with dark theme

-No major battery saving apps or settings with screen brightness of around 50%

-mostly WiFi with some LTE usage, an hour worth of phone calls, plenty of Facebook, FB Messenger, texting and YouTube along with a few games

I just got a little over 8 hours screen on time. Before flashing Superman ROM and removing system apps I don't use, I was barely getting 5.5 hours. Latest reading was 8 hours 2 minutes of SOT with 15 minutes remaining at 2%.
[Samsung Galaxy S7 Real Life Review] ashiskar:
I m on august security patch on my S7.. getting a screen on time of 3 to 4 hrs on mobile data.. 4 to 5 hrs on wifi.. on mobile data i m using 2 sims.. it dries up pretty easy. 2nd sim has 2G only. May i know what can increase the SoT.

NFC and sync auto was on. Screen on FHD.
[Samsung Galaxy S7 Real Life Review] stefanmaximum2:
thats about avarage sot i got with my s7 exynos i am pretty happy with that.. when on wifi about 5h i get 80% time, on mobile data 3h to 4h i think i 70% ~ 3:30h on 4g :) (i play few round of clash royale, into dead 2 , clash of clans, youtube, facebook, reddit, few calls)
[Samsung Galaxy S7 Real Life Review] Soufiansky:
Getting same too with bunch of apps installed, AOD sometimes and music, very happy with battery life it get me a full day of usage everytime, sometimes i get back home with +50% ( August firmware)
[Samsung Galaxy S7 Real Life Review] ashiskar:
Anybody got the october security patch update in india...yesterday it came? I accidentally pressed cancel.. now its not showing..
[Samsung Galaxy S7 Real Life Review] thevibas:
Just a Pop-up

It must be just a pop-up, to remind you to check on software updates. Try to check manually once if there is any you'll get it. Even i'am looking for updates but they didn't release it for India yet. Let me know if you get?
[Samsung Galaxy S7 Real Life Review] Levan_i:
Disabled Facebook app and Facebook messenger, installed lite messenger instead, and Metal for facebook. My screen on time increased from 3.5 hours (avarage) to 4.5 hours if using 4G and to 5.5 hours if on wifi.
[Samsung Galaxy S7 Real Life Review] ashiskar:
Got the october security patch update today. 490mb update. I eill update on device performance.. no lag or no crash till now..
[Samsung Galaxy S7 Real Life Review] thevibas:
Thank you for letting me know, i just got mine it's 414 MB, gonna update in a while, i'll post if there is any changes in SOT.
[Samsung Galaxy S7 Real Life Review] Levan_i:
Got November security patch yesterday, I guess nothing has changed...
[Samsung Galaxy S7 Real Life Review] ashiskar:
SOT is almost same.. no issue with network reception..the SOT is almost same around 4 hours with mobile data with heavy usage... The typing is now fast.. i face a typical issue with Asphalt 8..while playing any ad.. the app freezes and becomes blank sometimes.. i thought this update will improve that..but it does not ..it seems the Gameloft issue..anyone else facing such issue...
[Samsung Galaxy S7 Real Life Review] Levan_i:
And also tried factory reset, but still the same, 4.5-5 hours SOT is the max I can get (with FB and some useless bloatware disabled using Package disabler and lite messenger installed, no autosinc/NFC/Bluetooth/location/AOD. WIFI and LTE mixed).

Anyone still getting 6+ hours of SOT after last few month's security updates? If yes, please share, that would be highly appreciated.
[Samsung Galaxy S7 Real Life Review] enjoylife1788:
It has been released for India. I am sure you would have received it as well. Don't find anything new but for a size of 400 plus mb there has to be something more. No detailed changeling available anywhere.
[Samsung Galaxy S7 Real Life Review] Colday96:
I'm getting about 5 hours of screen on time
[Samsung Galaxy S7 Real Life Review] artaniss11k:
I get 7h SOT but to achieve this i set gpu frequency to max 260mhz, big cpu governor to relaxed and little cpu governor to conservative.
[Samsung Galaxy S7 Real Life Review] DarkerJava:
Getting 7-8 hrs SOT, phone is still kinda new though...
[Samsung Galaxy S7 Real Life Review] FcukBloat:
hi guys sorry but I just bought a second hand s7 (no edge) and I am very disappointed with battery life and charging speed.. even with quickcharge 2.0 I had at home it took more than 2.5 hours yesterday to charge completely. and today from 93% this morning I am already with almost no more juice (31% battery left... after lunch!!) and I barely used the phone today (46 minutes sot...)

that's damn bad, never seen such bad battery performances in any phone I owned

it is not a problem of apps or syncs etc, I use the exact same apps and usage as my previous phone (mi5) that used to last a complete day without any problems. no gps, no syncs, not bt etc etc

maybe I have a bad battery? but in cpu-z it says battery is good...

also the phone warms up pretty easily even with very low usage or phone in idle.. I think the exynos in these phones is a very ****ty cpu.. what you think? any suggestions? maybe I really have a bad unit... tia!

ps. the stock charge that comes with the s7 is 5V 1A? because this is what they gave me... but seems strange to me just a 1A charger with such a phone?

pps. and almost all time I was on wifi!
[Samsung Galaxy S7 Real Life Review] fracarol:
Exynos is not a bad CPU at all, the normal charger is 2A 5v, Samsung's "adaptive fast charging" etc works at 9V 1.67A for exynos

For battery life check signal strength and make sure you have nothing wrong running, you can easily monitor temperature and battery usage (and even signal strength I think) with Gsam battery monitor (and a simple ADB command)
[Samsung Galaxy S7 Real Life Review] FcukBloat:
thanks for the answer sir, so will try with a 2A charger and see if it will be faster (I will keep fast charging disabled though as someone reported that when usually fast charging the next charge cycle will last much shorter).

as said I am having same usage, sim and apps as my previous phone, and I always use the phone the same way, and the battery completely su*ks only with this phone... plus I even tried booting in safe mode (so with no third apps activated at all) and phone heats and discharge quickly even there... :confused: will do some more tests and report btw thanks in the meantime!
[Samsung Galaxy S7 Real Life Review] fracarol:
No problem? I have an old S3 neo charger that comes out at 1A and it's considerably slower than "normal" charging at 2A, that is quite fast (but fast charging is definitely faster) so I think that you don't have any charging problem

The overheating issue is really strange.. the fact that they did not sell you the original charger is strange aswell; hope you'll find a fix, maybe reinstall software with smartswitch or something like that
[Samsung Galaxy S7 Real Life Review] DSF:
Actually s7 is well known to heat up while using (or charging) chrome, facebook, heck, even YouTube can make the phone annoyingly hot. I've used the s7 exynos for more than 1 year and i can confirm that the device is far away from being cool (as temperature). Also the battery life was..meh.

And that happened on s7 edge too, a friend of mine had the exynos variant.
[Samsung Galaxy S7 Real Life Review] FcukBloat:
thanks guys for the answers!

ok so after a few days I can confirm that:

- using a 5V 2A charger, charging time is pretty good at last!

- it may be a case, but not using the above mentioned apps the phone is not heating too much anymore (was using only chrome of that list though, now I am using firefox)

- charging normally (not rapidly) seems the battery is much better: I can achieve about 24 hours and 3 hours sot now with my regular usage (not so good, my previous phone-mi5 was much better, but well could leave with that!)

if the phone settles like this, I can stay with it some time I think. I have to still test camera performances deeply.. but so far it is pretty disappointing as well for me :crying: (I expected especially low light pictures to be better than what I used to get with my mi5, but actually they look pretty the same to me :crying: )

thanks again guys for the suggestions!
[Samsung Galaxy S7 Real Life Review] fracarol:
That sounds good mate :)

Anyway more or less in one month and a half samsung should roll out oreo and I think it will be worth the wait so be confident (and patient too because Sammy isn't that fast in rolling out things lol)
[Samsung Galaxy S7 Real Life Review] FcukBloat:
yeas for sure! and maybe it will also improve battery life as seen in other phones? hope so! :o:p
[Samsung Galaxy S7 Real Life Review] Sportfreunde:
It's not bad but I'll be honest, it's not any better than the Moto G I got in 2013 when it was on Kitkat lol. Now of course this phone has a more powerful processor and the screen is 5.1" instead of 4.5" and it has a higher resolution but out of the box, I could get that Moto G to around 5-8 hours and it's pretty much the same as this and it will probably decline under 4 after an year or two :(

I am gonna avoid using FastCharge unless I have to though, might as well try to preserve the battery a bit.
[Samsung Galaxy S7 Real Life Review] ajebulon:
If you buy a 2nd-hand one, you should check your current battery capacity, because the battery will deteriorate after 1-2 years of usage. I checked the capacity using this app. In my case, after about 1.5 years, only 50% of its original capacity was left. Even when I tried normal charging, the phone would fill up to 100% in less than 1 hour of charging. If your current battery capacity has already dropped like mine, you should consider to change your battery. I just changed it to the service center, and it took only 20 minutes to change it, and it cost 35k KRW, around 32 USD, and now it's as good as new.
[Samsung Galaxy S7 Real Life Review] Soufiansky:
Not my case,it nevers gets hot even while gaming. (S7 flat,exynos)
[Samsung Galaxy S7 Real Life Review] *Detection*:
Same, only gets hot when fast charging on using it in the Gear VR, nothing else
[Samsung Galaxy S7 Real Life Review] fracarol:
My S7 gets hot all the time (talking about battery temperature detected by Gsam battery monitor) in summer with high temperatures outside so it can't dissipate heat to the environment. Now during winter it's doing fine

*Hi sir,I am a redmi note 4 snapdragon(mido) user,my mother just got galaxy S7 I don't know whether exynos or snapdragon but it's model No.is

SM-G930FD,I used it for a while and thought that the battery was draining,but thought I was over thinking because I am used to using my phone and maybe experiencing high drain.I came back home today after college and I still think battery is draining quite fast.I want to attach the screenshots and if possible clear my views about whether battery is good or not.Had disabled AOD yesterday only and reduced screen resolution from fHD to just hd.I can give the battery stats after full battery use or maybe till 10% or 5%!

Please help and guide me

The phone is dual sim and got around 4 hrs 15 minutes of SOT!
[Samsung Galaxy S7 Real Life Review] fracarol:
Hi, that SoT is pretty normal I think, maybe go to settings - apps and disable everything you do not need
[Samsung Galaxy S7 Real Life Review] Krashtan:

How do you reach 8 hours?

Would you mind tell your setup please?
[Samsung Galaxy S7 Real Life Review] Djuganight:
that is a lie.

If you put it to charge in between and without restarting the timers don't reset.

That time is not correct and impossible even only with just normal usage.

It's superman rom

[Samsung Galaxy S7 Real Life Review] justinchao740:
IDK how u guys getting over 3hrs sot on ur galaxy s7. i have an AT&T galaxy s7 SM-G930A with an engineered boot image for root and i get around 2-2:30hrs of sot during the day with android system always on top of battery usage at 25-30% by the end of the day.
[Samsung Galaxy S7 Real Life Review] SIGMAxB:
I was also disappointed by the battery life on my newly acquired s7 until I tried the Oreo leak for att granted I have no root but feel like I don't miss it....
[Samsung Galaxy S7 Real Life Review] SIGMAxB:
So far one change I've made is not using fast charging it just seems to make my phone discharge faster
[Samsung Galaxy S7 Real Life Review] fracarol:
I never use fast charging and I get relatively decent discharging rate, I don't think the two things are related anyway I don't know what could interfere. It's the only thing you changed?
[Samsung Galaxy S7 Real Life Review] Krashtan:
It is not a lie. I was using my phone for 10 hours straight. That's why such a good Sot. Plus I have uninstalled bunch of apps and slightly tuned super man rom.
[Samsung Galaxy S7 Real Life Review] *Detection*:
It's easy to get 8+ hour SoT if that's all you do with the phone, leave the screen on and nothing else

I've reached higher than 8 hours SoT easily by doing nothing else, but that's cheating, it is not normal usage

If you look at the list of apps used during that time the screen will be at the top, then probably system and OS etc, no apps that use much battery will be there in that list

Version ROM makes no difference, you can't get 5 hours SoT with stock then 8 hours + with another custom ROM, impossible unless you cheat as I said above and just leave the phone sitting with the screen on doing nothing all day
[Samsung Galaxy S7 Real Life Review] Bleak3993:
What kernel and ROM are you on? How's the usage performance?

Any of you have tried greenify, L speed or HEBF?

I'm really looking a way to improve battery performance
[Samsung Galaxy S7 Real Life Review] waingro808:
Snapdragon S7 Verizon from June 2016: I can get 5.0 hours SOT over 24 hours or 3.5 hours SOT over 48 hours. Data, wifi, bluetooth on all the time. Location off when not in use. AOD disabled of course.

Love it.

---------- Post added at 09:52 AM ---------- Previous post was at 09:45 AM ----------

Engineer kernel sucks. Go back to stock or G930U firmware and use Package Disabler or SABS to disable bloat.
[Samsung Galaxy S7 Real Life Review] justinchao740:
i currently have the g930U firmware with basically no bloat and im still not getting your battery performance
[Samsung Galaxy S7 Real Life Review] waingro808:
Try turning Location off when not in use. Also, in Settings->Battery->Always Sleeping Apps add all the stuff you rarely use (works like Greenify, but not as aggressive). I have never used fast charging, which may have kept my battery healthier in the long run.
[Samsung Galaxy S7 Real Life Review] justinchao740:
already did all of that...
[Samsung Galaxy S7 Real Life Review] waingro808:
Your battery is dying then if you still can't get 3 hours SOT.
[Samsung Galaxy S7 Real Life Review] thienquang07:
I had got 7 hours SOT with 5% battery left, and it happened only once, no twice. Normally, I got 4 hours SOT before, and just 3 hours now. I know the phone can get over 5 hours SOT, in some specific condition, but I don't know how to set that.
[Samsung Galaxy S7 Real Life Review] Jino Eg:
Too less

I hardly get 3:30 to 4 hours
[Samsung Galaxy S7 Real Life Review] waingro808:

amazing battery life with ultimate nougat 2.5 .. debloated i have the S7 exynos 5 months old
[Samsung Galaxy S7 Real Life Review] Soufiansky:
Android system sucks too much battery, but the funny thing is that this is still a pretty nice endurance..Do you guys too have AS using that much battery ?
[Samsung Galaxy S7 Real Life Review] fracarol:
Me too, that's why Sony or other phones last longer than Samsung with same CPU and battery (Sony actually uses smaller batteries and still lasts longer), bad optimization
[Samsung Galaxy S7 Real Life Review] Soufiansky:
Happy to know i'm not the only one...and this always happen 1.5-2years after the phone is released somehow, had the exact same problem with 2 previous S6's. Guess it's time to flash a custom rom.
[Samsung Galaxy S7 Real Life Review] fracarol:
I bought it when S8 was already out so I can't tell, anyway personally I'll wait Oreo then I'll have a look to some custom kernel. Custom ROM on Sammy is always to be considered yeeppp

[Samsung Galaxy S7 Real Life Review] grigo1008:
Just got the Oreo update a few days ago, hoping that my SOT and overall battery life will increase. Still only getting about 1.5h - 2.5h of SOT on my Exynos G930f... Other users dont charge their phones for up to 2 days and get 3-4h of SOT. Some even get 5-6h of SOT daily. I disabled all bloatware packages using Package disabler Pro, have a black theme, AOD off and mostly on 4G with data saver on when im not home. Any other users having the same problems? I know this thread is pretty old but I still hope to get some help or hear about other users having the same problem. I will try to provide some screenshots of my battery usage but the problem is that I always plug my phone in when it is possible...
[Samsung Galaxy S7 Real Life Review] fracarol:
What apps do you have installed? If you have any, uninstall things like Avast etc. You may try forcedoze or something like that. Sot depends on what you use your phone for but 1.5h seems too little to me. Look after Google services too, you can monitor battery usage with Gsam battery monitor (you need to give adb permission to both forcedoze and Gsam but nothing to worry about)
[Samsung Galaxy S7 Real Life Review] grigo1008:
Thanks for your quick reply! I already monitor my phone with accubattery and Gsam but there arent any noticeable apps that take a lot of battery. Accubattery shows me that I have about 85% of my battery. Could that be the problem? Also I have quite a lot of apps installed (I blocked notifications in most of them) and actually installed forcedoze a few days ago. Im going to try and give adb permission to those apps. Also I turned background activity from google services off but that doesnt make a lot of difference.
[Samsung Galaxy S7 Real Life Review] fracarol:
You're welcome ;) 85% of your battery is not bad anyway I don't think those estimates are really precise. If you really need all those apps maybe you can try to erase all data for every app. Anyway there must be something that drains your battery so at least battery statistics in settlings should show it. You can give malwarebites a run too (but after that uninstall it heheh). It'd be nice if you could post some battery statistics anyway :)
