No, it does not matter how you charge your phone. What matters is the capacity of your battery and how you use it. 3 A battery will still be 3 A battery regardless your method of charging. Also, my fast charger is not working anymore and for about 3-4 months I have been using a normal charger and i saw no improvements in battery life.

As for my experience with this device, battery life is very weak. Android System is always first in consumption list, then on 2nd, 3rd and 4th place are Screen, Android OS and Cell standby/Device Idle (not always in this particular order). I have tried everything to increase battery life (Greenify, PackageDisabler Pro, Truned off AOD, Truned off Mobiled Data -> only used it when i needed it, disabled Facebook and Facebook Messenger), nothing works. On a single charge I get ~3h of SOT.

Overall i am satisfied with this phone, build quality is very good ( minus build quality of the home button, which for gold model the color is peeling), performance is top notch, the display is gorgeous, but battery life sucks big time.

my phone get 2 hour max sot in android 7 (BTU) im think some thing in backgeran eating my battery how to fix it ?
[Samsung Galaxy S7 Real Life Review] kahush:
When using the first Nougat beta firmware I could achieve 4+ hours of SOT. Moving on to BTU or PHN firmwares nothing. Such dismal performance, S7 can barely hit 3 hours. Thinking of going back to MM.
[Samsung Galaxy S7 Real Life Review] :
People, you must be dumb or something.. because you still compare stupid SOT when there is uncountable number variables..

Like for example.. today I am at 43% battery and only 2h10m SOT.. I should be crying here as you all do right ?

But no, I have weak reception where I live, I am using fitbit charge 2 with constant sync, handsfree in car, company VPN app with emails and so on, and this is after 2 days and 7 hours standby.

Screw your SOT comparison and get some real data instead.

If you want to compare, all of you just restore factory defaults, do not install anything, start up chrome and run a video on youtube while on wifi and then tell us how long until battery dies.

Or run the same benchmark, there are some for battery life out there.

There are so many variables like programs installed with push notifications and background sync, reception of your network, wifi or no wifi, bluetooth or no bluetooth devices, gps usage, brightness level, screen resolution, games or no games, GPU/CPU intensive apps or not, google location history enabled or disabled, etc. etc.

Exynos s7, 1 day of heavy usage on superman rom with superstock kernel . Love this phone even after 10 months !

Edit: full screen on time with 5 % left was about 7 hours.
[Samsung Galaxy S7 Real Life Review] turikos:
I achieved this on SuperMan ROM with SuperStock Kernel and a few apps frozen with LuckyPatcher
[Samsung Galaxy S7 Real Life Review] Redeemed222:
Factory reset, cache wipe, reset app preferences, then added my apps back one by one, turned off all location settings on the device, turned off all WiFi connections when not in use, turned on medium battery saving mode, data saver. I then let the phone settle like that for a few days. Then put my netguard back on with all system apps blocked when not in use (that's just my preference paid version). Then added BK package disabler to disable unnecessary running apps and last I use the donation package of Greenify to handle some system apps. I'm still getting 8 hours screen on time and if I use my phone casually I'll get 48 hours of use. And it's not magic :)

Decided to take this session to 1%. I played Words practically the whole time. Played Mario Run and browsed the web a little in between. This is a non rooted T-mobile S7 with 9.5 hours SOT after constant gaming. It took me 3 weeks to configure this phone after installing Nougat and for some sick reason I enjoyed every minute of it.
[Samsung Galaxy S7 Real Life Review] egps2:
On Exynos G930F on Nougat I can easily get 7+ hours screen-on time and I am extremely happy with the phone and the battery life since moving from an S5 this week. This is with CPU powersaving on (background data enabled), WQHD resolution and a dark (not black) theme called "Material Dark". The dark grey background helps prevent the ghosting amoled artefact seen with black background and low brightness.

I have disabled a few apps I never use like Google Play Movies but otherwise have not rooted to disable anything and no longer need ForceDoze as was necessary on my S5!

EDIT: The stock battery screen usually suggests that "Screen" uses the most battery whilst "Android System" is a close second at 2/3 to 3/4 of whatever screen uses. Also note that you need to set custom profiles in the GSam Battery Monitor app for wifi and calls or they will both look artificially inflated. With these corrections GSam reports screen using about 25% whilst "App Usage" is about 70%.

Cheers
[Samsung Galaxy S7 Real Life Review] Redeemed222:
Not sure sure if you're referring to my stock battery screen. I use NetGuard so all my usage from my apps gets attributed to it. That makes it show higher than screen.

Nowadays i barely get 4h SOT in a span of 20h-26h. And this with FHD.

When i first installed the beta I got near 6:30-7h of SOT.

I love android battery life! Inconsistent as its ram management ?

Approx 4h SOT in approx 20h... Resolution set on HD. Most of the time on wifi. No Bluetooth, no nfc.

No issues with WiFi battery drain here, 4G drains way faster
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Yup exactly.

On wifi i can get 6 - 7 hours while on 4g i get max 4 hours if not even less.
[Samsung Galaxy S7 Real Life Review] robertkoa:
You Guys with the 6 to 7 hour SOTs are usually on the Exynos version- right ?

Please tell me that you are NOT mixing in WIFI TIME to the SOT Statistic.

WiFi obviously uses far less battery because there is no transmit / receive to the Tower on WiFi.
[Samsung Galaxy S7 Real Life Review] Djuganight:
I have one exynos and my wifi drains battery much faster than data connection. Much more!!!

Is this on 4G or on WIFI ?

Exynos or Qualcomm ?

---------- Post added at 08:36 PM ---------- Previous post was at 08:18 PM ----------

I never use a phone at Full Brightness unless I am in the Desert with my Camel - and I don't have a Camel and have never been to the Desert.

SOT with Video Use OR Web Browsing ON a 4G Network (*NOT WIFI ) at a fairly low brightness 20 to 30% is a reasonable way to Compare...

Why NOT on WIFI - Because IF you have WIFI you probably have POWER and access to a charger.

And WIFI uses less Battery by far.

So is this a CONTEST ?

No - if someone with a removable battery Device for example wants to' Upgrade' to a fixed battery Device- possibly- like me I want to know if I can Web Browse and Do other things with no Charger Access for 5 to 7 hours SOT - if not Device might not be worth it.

Agree that it's difficult to assess everyone's usage but you can get some idea and see how they are getting larger SOTs if you sort differences and average them...possibly.

Sure Playing YOUTUBE at %30 brightness on 4G Continually would be interesting but few will actually do it...I think.

---------- Post added at 08:48 PM ---------- Previous post was at 08:36 PM ----------

Thanks for the Reply- IF on WIFI the phone is not directly transmitting and receiving to the Towers -

SO THAT is THE BIG VARIABLE in these Reported SOTs along with Screen Brightness.

IF you are on 4G all day - your SOT would be far lower.

---------- Post added at 08:57 PM ---------- Previous post was at 08:48 PM ----------

They are probably on WIFI Network which uses far less Battery....
[Samsung Galaxy S7 Real Life Review] olafsand:
For me wifi takes more battery than Lte. Router is in same room with me.
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Nope and if i mix it i probably use it a little, like going out for 30 40 minutes. On mixed usage i get an average of 5 hours. Yes i am on the exynos version.

EDIT: Why are you so sceptical? I have posted multiple screenshots on this thread all the way back from summer 2016 when i got this phone. Since then i have moved and my usage is quite a bit different and i have also changed a lot of roms . The only thing which really makes a big impact on battery for me is gps + a lot of brightness . What i have noticed is that whatever usage i had , i never got below 2 hours of sot at 50 %. No matter the brightness or gps , aod , nfc ,bluetooth and whatever. So my point is that the minimum for ths phone is 4 hours on exynos.

Once i also had my phone marathon through 3 days of usage since i was on a vacation and didnt have to use it. 72 hours of standby and 3.5 h of sot in the end.

[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Snap/ exynos?
[Samsung Galaxy S7 Real Life Review] DSF:
Exynos.

Aprox 95% on wifi, 5% on 4g with data.

Bt off, nfc off, location on (this is not the culprit anyway)

The device gets hot randomly when using (facebook, skype messages only, facebook, youtube) Always hot on 4g. Same issue as on s6 edge.
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Skype was giving me issues too. Try to live without it for a couple of days and see if there is any difference. Also download gsam battery monitor to see what is draining your battery.
[Samsung Galaxy S7 Real Life Review] DSF:
I logged out from skype for 1 day, no usage at all. The same crappy battery life..
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Have you tried a factory reset?
[Samsung Galaxy S7 Real Life Review] DSF:
I've just cleared the cache via recovery mode. I will see if this helps or not.

Factory reset is a no solution.

Even after i've flashed the nougat beta i didn't hard reset and got got better battery life (sometimes i nearly hit the 7hr SoT).. but the inconsistency was there since i owned the brand new s7 :).

Who is to blame? Samsung? Google?
[Samsung Galaxy S7 Real Life Review] *Detection*:
Should always factory reset after a major OS upgrade

User is to blame if you don't
[Samsung Galaxy S7 Real Life Review] DSF:
That's a misleading advice highly promoted here :).

You simply don't need. Nor this will solve the issue.

Unless you turn off internet and don't install apps after the reset. But you can do this even with no reset.

But this can be properly solved by switching to a dumbphone, such as a nokia 3310 :)
[Samsung Galaxy S7 Real Life Review] *Detection*:
You must be new here, it is always advised to factory reset after a major OS upgrade, otherwise you end up with problems like battery drain

Been the case for as long as I can remember
[Samsung Galaxy S7 Real Life Review] DSF:
If you have read my message completely, you would see that after i've updated to nougat beta (with HOME_CSC) I got better battery life than android M. No hard reset, nothing.

And, this is a general issue I have with android. It's not limited to s7. I had battery life problem with s6 edge too. Out of the box. That one I factory reset, and helped with completely nothing. :)

(in this case) Factory reset is a poor solution for solving something temporary <till you complete your setup: apps, actually USE apps, accounts, etc> :).
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Try a different google account ... maybe something is wrong with your settings ..how old is your phone?
[Samsung Galaxy S7 Real Life Review] dmf77:
I was having same issues since upgrading to nougat, 2 hours screen on time, no matter what, getting hot all the time... Finally broke down and factory reset, everything is perfect now, 6 hours screen on time minimum, no overheating at all...
[Samsung Galaxy S7 Real Life Review] *Detection*:
He doesn't think it is necessary, nor thinks it will solve the problem, even though hundreds of people throughout multiple devices and Android versions over the years have proven otherwise

He's knows best obviously so let him enjoy his crappy SoT / Battery life
[Samsung Galaxy S7 Real Life Review] DSF:
Lol. Factory reset is the easy solution and temporary for some. If it's app related: If you install and use the same apps before, factory reset in vain.

Anyway, it seems the overheating problem is gone after a wipe cache :). That's something what a factory reset also do but with everything else gone :))

And Detection, no need to be sarcastic. I just say that factory reset is actually not a solution for every problem. Of course it will fix stuff but you can make it without losing everything. It's like you broke something in your car and the service advice to change all the parts instead analysing and fixing the source problem.

Personally i had enough of reading people recommending to factory reset for EVERYTHING. Old xda is gone.
[Samsung Galaxy S7 Real Life Review] DSF:
My phone is 1y+ old.

I have to rekon that i am using google now launcher with google now activated, location history enabled (but this shouldn't affect battery life when stationary), Samsung health stepcounter, and so on. Mostly on wifi. But no: bt, nfc, device scaning, nearby devices, AOD.

I have plenty of apps installed too.
[Samsung Galaxy S7 Real Life Review] *Detection*:
Actually you actively broadcast this fact about factory resetting to fix battery life problem (And I quote you with) "You simply don't need. Nor this will solve the issue."

When in fact you are completely wrong, you do sometimes need to, and it does generally solve the problem, otherwise no-one would do it or recommend it.

Backtracking now won't change what you said, I did not say it would solve every problem, as everyone can plainly see, I said it is recommended to solve battery drain problems and other issues after a major Android OS upgrade.

As for 'The old XDA' whatever that means, why spend days/weeks troubleshooting something you know you can solve with a reset, and have your phone back up and running problem free in a few hours or less?

Especially when there is a good chance you can not solve it without a reset because the problem lies with rubbish files left over from the upgrade

If you have ever upgraded a Windows PC, you should know a clean install is 100% of the time the better option, same goes for Android
[Samsung Galaxy S7 Real Life Review] DSF:
If x drink too much and goes to hospital, then after he exit from there he continue to drink a lot.. will his issue be fixed?

Fix the root of the problem.

Factory reset may be a temporary fix if you're installing all your stuff over again.

And for me a hard reset it's definitely NOT a solution. Maybe when android reach the level of ios backups, to restore everything (including fingerprints, credentials, app data) with one click and no fuss
[Samsung Galaxy S7 Real Life Review] *Detection*:
Your comparisons are terrible, the problem comes from the upgrade, the fix is a reset, end of story

Sometimes you are just wrong, this is one of those times for you, as you have just been shown by other members, if I was you I'd quit your pointless charade as it is just making you look dumb.

Enjoy your terrible battery life, you are now on ignore, conversation over.
[Samsung Galaxy S7 Real Life Review] DSF:
Lol, the problem comes from update? And that says everything about it.

Actually i've got better battery life after upgrading to nougat from marshmallow. Even with home csc flashing and no factoey reset. But hey, you know everything.

I am stopping this pointless discussion. And btw, you look like acting smart (and i don't think it's the case).
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
You have 244 apps installed?
[Samsung Galaxy S7 Real Life Review] DSF:
Something like that :D
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
Well if i were you , i would ve tried a reset. But since you dont want to and/or that is not an option i suggest you try something different. Are you using fast charging?
[Samsung Galaxy S7 Real Life Review] DSF:
Well, even after a reset i would still have the same amount of apps cause i would opt in for google play auto installing previous apps.

I am using fast charging.

Anyway, after wiping the cache, the phone doesn't overheat like before. Got about 4.30h SoT while also updating the software (which consumed about 10%).

People who reports 7-8h SOT may be using the device lightly. Browsing with chrome (i tried to like samaung browser but cannot) and on facebook consumes more battery. And unfortunately Facebook feels so unoptimized.
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
I get 6.5 hours regularly. Its not light usage , its just constant usage. What i mean by that is for example over a 15h period i use the phone 3 h non stop and then use it for 3.5 h again without letting it go. 4.5 - 5.5 is normal over a day of usage for this phone. This has been proved many times and i have also done it myself. 7 h or more is again constant usage but with a lot of videos and/or browsing the web. I have also achieved this. Anyway try to drain it to around 5% and turn fast charging off and let it charge and see if that makes a difference. How is your signal coverage?
[Samsung Galaxy S7 Real Life Review] DSF:
My signal is most of the time 4 bars, but right now strangely 3 bars. I am using 3g/2g since lte signal is weak.

Can you please check thr battery temperature after about 30min-1h of continue usage (on wifi)?

Mine is 35.4 C. 27-28 C ambiental temperature.

Chrome, facebook, youtube, skype (im only)

Factory reset, full charge, keep apps to minimum, then test. Post battery screenshot after doing so and we can all work from there. :cool: Otherwise, not enough information to really advise. :silly:

You could have background apps, bloat apps, third-party apps, or something else sucking your battery away. :confused:

That being said, your battery could be older or more used than others. Maybe replace the battery, or root the device for comparison :fingers-crossed:
