[Samsung Galaxy S7 Real Life Review] balag59:
Hi,

I'm on the samsung galaxy s7 T-Mobile model on tmobile network and I've been having pathetic battery life to say the least.I barely get 12 hours total time on battery with 2.5 hours screen on time. This is without using always on display or a lot of 4g.i don't play any games or have Facebook Instagram etc installed on the phone. I have good signal strength most of the time so no problems with that either. Is the battery life on this phone really that bad or am I just facing issues? Funny thing is android system takes 15% and android os takes 9% of the battery and the screen takes up just 8%. It also seems to be awake for a very long time like 3hr in 12 hours total time. Unfortunately I'm not rooted and was looking to avoid that.i have disabled everything I could without root and tried factory reset a few times. Attached are some screenshots. Any help would be much appreciated!

Thanks!

I faced this in my previous phones. A hard reset will be appreciated. It'll solve your problem.
[Samsung Galaxy S7 Real Life Review] jerusalem.boy:
you described my problem maybe we need to buy a new battery even my phone age is less than 10 months :(:(
[Samsung Galaxy S7 Real Life Review] jerusalem.boy:
I put all app in save mode and I get 12h on battery and 3.5 hour and I'm on WiFi all the time :(

I'm going to make backup of my data so maybe I can make factory reset... and I thought I face the problem since android 7 update :(
[Samsung Galaxy S7 Real Life Review] AngelxCasas:
Quick question...

I'm about to purchase a second hand phone (I'm on iPhone 7 rnow) and I don't know if I want the lg G5 or galaxy s7 FLAT, I used to love the s7 because it bestiality battery life, but now I see that everyone get only 3-4 SOT... the problem is android N? If I bought the S7 and downgrade to Marshmallow can I have better battery life?
[Samsung Galaxy S7 Real Life Review] DSF:
I do not recommend the s7. Especially if you're gonna use it on mobile data. This beast heat up so hard!

Actually i got better battery life on nougat than on marshmallow.

I even got near 6-7h sot. But rarely and only on wifi and stationary.

If a dynamic day (work, walk, 95% wifi, 5% data 4g), in about 21-26 hours i can get about 3-4 hours of sot 99% wifi, 1% data). Also it tends to heat to basic stuff like youtube, chrome (don't blame javascript!), Facebook, etc. Not to mention that i feel it warm when on my pocket and data enabled...

I leave wifi always on, data always on, location on (tried with this off, same results because the location is triggered rarely or when using google maps/navigation), accounts sync always on. No nfc, no Bluetooth.

Deactivated location history.

Maybe look elsewhere, for eg, the OnePlus 5? As far as i read, rhat one doesn't heat so much that you can fry eggs on it and also it has better battery life (but yeah, you lose the compact form of the s7). I know i will switch soon :). Started to hate also the back glass too! I will happily ditch the wireless charging for a metal back. (I've used the wireless charger only few times)
[Samsung Galaxy S7 Real Life Review] fracarol:
After all g5 should have less battery life than s7 and probably with android o the s7 will improve again (I hope)
[Samsung Galaxy S7 Real Life Review] lumikin:
would it be too much hassle to shed some light on what you may have done to achieve this? i am quite familiar with synapse tuning, any input would be great! hopefully you are not suffering any UV issues/crashing.
[Samsung Galaxy S7 Real Life Review] josanmpole:
i have a S7 on Nougat but my battery drains fast. at 100/100 it shows 11h left. is it normal. now at 68/100 it shows 7h2min. is it normal ? please respond me

at 57/100 i have 6h remaining . SOT is 1h36min since 100/100

1/100 with only 3hr15min SOT. i must admit that my s7 battery drains fast
[Samsung Galaxy S7 Real Life Review] DSF:
I fixed the s7 weak SOT by switching to another phone ;) :eek:

Gaining easily 9 SOT in same conditions. :laugh:
[Samsung Galaxy S7 Real Life Review] zeldaxlove64:
10 mins sot 94% left is this normal?
[Samsung Galaxy S7 Real Life Review] roniebranco:
S7 edge exynos with stock nougat rom

14h of usage and 5h of SOT with 50% battery left

Moderate usage: wifi only, Facebook, YouTube, WhatsApp, Clash Royale, browser, etc...

How to get this SOT: package disabler + greenify + Agressive doze + power saving + HD resolution + location disabled

3 hrs SOT 26% what the hell happened on my battery?
[Samsung Galaxy S7 Real Life Review] Hidden Username:
all i do is use reddit on my phone but never get more than 3 hrs
[Samsung Galaxy S7 Real Life Review] borg17a:
I think 3 hours SOT is normal (S7 - Exynos).
[Samsung Galaxy S7 Real Life Review] *Detection*:
I average 6 hour SoT using mainly WhatsApp, texts and camera
[Samsung Galaxy S7 Real Life Review] borg17a:
And we still don't know what's "normal"...
[Samsung Galaxy S7 Real Life Review] *Detection*:
5-6 hours has been the average people get with the S7 flat, there are exceptions where people get way less, and some who get more, but generally 5-6 hours is what you should be getting
[Samsung Galaxy S7 Real Life Review] MikeSome1:
AccuBattery says I should get 5 hrs sot with moderate usage, but in my experience, my s7 gets around 3-3.5 hours when browsing web, gaming (around 1-1.5 hour), using maps

Probrably gaming is the main reason for not getting those 5 hrs

Let's be honest these days You have to be able to charge a phone, days of old Nokias lasting weeks are gone ;)
[Samsung Galaxy S7 Real Life Review] DSF:
Mike, trust me i was so frustrated because of the ****ty SOT i got with my usage and also how easy and hot this thing get!!!

So my only solution was to get rid of my phone.

And now with the OP5 i can get even 9h of SOT (with not too much idle, about in 20h in total), and in average about 2x-3x battery life of the s7 exynos. Not to mention that the device has much much better perceivedvtemperature. Again, with my usage.

Sorry for mentioning other devices, but after owning multiple Samsung galaxy s devices i got tired and ditch the brand. And boy i am not regretting.
[Samsung Galaxy S7 Real Life Review] MikeSome1:
My s7 with Exynos also gets very hot sometimes. Maybe You are right that it's just galaxy s phones line problem... maybe with the next "upgrade" I will choose something else than samsung
[Samsung Galaxy S7 Real Life Review] fracarol:
My s7 too gets very hot, I asked a OP3 owner and his phone does not heat up as the s7. And heat is just energy (from the battery) that goes away instead of being used by the CPU. Samsung has great functions that other don't but the software is everything but efficient. So bye-bye SOT
[Samsung Galaxy S7 Real Life Review] Us3rNam3d:
1 year later i am still getting around 5-6 h of SOT daily , i am using the Batman s8 port, with Notorious kernel. Mixed lte and wifi. location on. aod off. bt and nfc off.
[Samsung Galaxy S7 Real Life Review] arturocs14:
only 4 SoT, why ? this is normal?
[Samsung Galaxy S7 Real Life Review] nicocastellarin:
Im getting 2 hs SOT I think there's something wrong with my battery as i have already cleaned cache and restored from default and it didn't solve the problem. In 3 minutes of use 5% of my battery drains
[Samsung Galaxy S7 Real Life Review] borg17a:
2h SOT - bad signal reception?!

Same here!

I even got a NEW BATTERY - no changes at all. I think it has something to do with bad signal reception. to me it seems like the S7 needs a lot of power for keeping Signal.
[Samsung Galaxy S7 Real Life Review] fracarol:
I thought the same thing, and it starts heating after a while I'm even just playing music (and heat is battery juice)
[Samsung Galaxy S7 Real Life Review] borg17a:
So you think overheating is related to bad signal reception? I would agree. I often feel the S7 gets warmer when I'm in a train where you hardly get a Signal.
[Samsung Galaxy S7 Real Life Review] fracarol:
I suppose it causes a part of overheating, generally maybe the software could be more optimised, or even the CPU running for nothing. Actually I notice something of overheating also in offline mode with light usage so I just suppose :p (now I'm trying to use the 3G only mode and we'll see)
[Samsung Galaxy S7 Real Life Review] DSF:
Mine overheated even with light usage (simple chrome browsing, youtube) with full bars signal. I guess that's why they did mount a passive thermal "pipe".. exynos is a hot beast.. literally :)
[Samsung Galaxy S7 Real Life Review] fracarol:
When I bought it I though that the thermal pipe was causing me to feel more heat as it pushes out heat, anyway the 14nm should be efficient. I try to keep the energy saving on so it should run at 70% of max frequency (and that should help to cool down) but that's the same. There's something wrong with that heat because the exynos is a "hot beast" (XD) when working hard but I don't think that chrome or music is that heavy usage
[Samsung Galaxy S7 Real Life Review] rand0m_insanity:
I get around 2-3 hours SOT for my S7 when at home. At first I thought it was software, but after a wipe and installing minimal apps, I still get similar results. However, when at work or elsewhere, I get like 4-6 hours SOT.

I noticed at home that I barely get any reception at all. At best, I get 3 bars. Most of the time, a steady 2 bars.
[Samsung Galaxy S7 Real Life Review] *Detection*:
On WiFi ?

4G uses way more battery for me than WiFi, but yea if it's constantly searching for a signal it will use more power
[Samsung Galaxy S7 Real Life Review] waingro808:
Correct. You will not get 5-6hrs SOT with gaming. If you want to game, get an Nvidia Shield tablet, lol just kidding.
[Samsung Galaxy S7 Real Life Review] stefanmaximum2:
How much on avarege can i expect from galaxy s7 edge exynos on optimized settings i am thinking about buying s7 edge? Would you recommend me s7 edge for about 460 euros brand new? Thanks :)
[Samsung Galaxy S7 Real Life Review] fracarol:
One thing is that it heats a bit too much (now), but some say that the august security patches will help fix this and battery life too. S7 edge will for sure receive android Oreo so it should improve in battery life and performance. Then it has an up-to-date design and good functionalities (and a quite big battery) so I think that's very good to buy
[Samsung Galaxy S7 Real Life Review] clemson.agr:
I must have a lemon or something. I've had this phone for about a month and can't make a single day without charging. I used it very little today and here are the stats:

Battery On time: 9h 37m

SOT: 1h 19m

15% battery remaining

Mid power saving mode on, wifi off, BT off, 2-3 bars, forced 2g-3g, App power monitor on, etc.

It has a Snapdragon processor. I changed the ROM from AT&T to a "U" on Nougat to try and help, but it didn't help. No bloatware. I'm thinking I have a bad battery and need it replaced?
[Samsung Galaxy S7 Real Life Review] *Detection*:
Yep, something isn't right, tried a factory reset I'm guessing?

And you factory reset after upgrading from MM > Nougat? Battery drain from major OS upgrades is common, reset is needed
[Samsung Galaxy S7 Real Life Review] clemson.agr:
I did not try a reset. I thought since it was a new upgrade to Nougat that it didn't need a reset. I will definitely try it soon and report back on the battery consumption. Thanks!
[Samsung Galaxy S7 Real Life Review] omer7:
Has anyone tried going back to MM? Did it improve battery time?

Because I m getting worse battery time on nougat, and thinking to go back to MM.

Any suggestions?
[Samsung Galaxy S7 Real Life Review] *Detection*:
I get better life with Nougat, well at least I did before the last couple of updates but I'm sure they'll fix that at some point

I did try going back to MM one time and battery life was no better, worse in fact
[Samsung Galaxy S7 Real Life Review] omer7:
Thank you for the response. But my phone's battery time has become worse on nougat. "Android OS" and "Android System" usage goes very high. Even higher than screen usage (if phone remains idle).

I did factory reset after updating to nougat. But now i m thinking before going to MM again, i will factory reset my phone once again to see if it improves battery time. Because no doubt nougat is better and apps UI, esp samsung stock apps UI looks good in nougat.
[Samsung Galaxy S7 Real Life Review] Klaudas:
1 year+ old and still getting 4-5h SOT easy. FB, snapchat, instagram, youtube all day. :highfive:

Superman v2.6, superstock kernel
[Samsung Galaxy S7 Real Life Review] fracarol:
That's cute

Anyway also here on g930f stock nougat I'm having very high battery usage by android operative system and android system (that is linked to all the Samsung services etc)
[Samsung Galaxy S7 Real Life Review] JustinNg93:
Did you use Wifi or mobile data? Did you make any configurations such as using kernel adiutor, greenify...? Thanks
[Samsung Galaxy S7 Real Life Review] omegahusky:
Hi guys I want to know if this is standard or if my phone is defunct.

I have a Sprint Galaxy S7 and using Gsam my battery life on average is 15h 10m (4h 16m Active), and Screen on: 2h 16m (2h 47m Max). I have Wifi on, Location on, AoD on, Bluetooth off, Sync on.

Is this normal considering I leave Wifi and location and AoD on or is this still worse than it should be? Thanks.
[Samsung Galaxy S7 Real Life Review] Klaudas:
No. 80% wifi :victory:
[Samsung Galaxy S7 Real Life Review] Levan_i:
I can hardly get more than 4 hours. Bluetooth, location, Auto sinc, NFC, AOD are always off, Facebook app disabled (and several bloatware also, using Package Disabler), only messenger and Instagram with light or normal usage. 4G is always on or wifi if at home. Was expecting at least 5 hours SOT before I got the phone and have no fckin idea how to get that result
[Samsung Galaxy S7 Real Life Review] waingro808:
Clear system cache. With phone off, hold volume up + home + power and follow instructions. That helped with my wife's phone after the latest update seemed to harm battery life.

---------- Post added at 04:47 PM ---------- Previous post was at 04:39 PM ----------

I would say that is below normal unless you are gaming.
[Samsung Galaxy S7 Real Life Review] zigmuntfavello:
on my wife's phone we have 6.5 hours with 9% left. 3G/4G connection all the time ;)
[Samsung Galaxy S7 Real Life Review] thevibas:
10 Hour 16 Minute with SOT 4Hour 10 minute' at 16% Wi-Fi on all the time. Stand by 3-4% every hour. GPS Off, Bluetooth Off, NFC Off, Auto Sync Off, Display Brightness Minimum all the time. Running Nogut 7.0 (Out of Box).

---------- Post added at 10:06 PM ---------- Previous post was at 09:55 PM ----------

Just moved to S7 from J7(2016). I've getting same back up on S7 as you are, Thinking to get back to J7(2016), Last full charged J7(2016) 3 day's 19 Hour's ago it still has 71% with 2 hour 13 minutes SOT, WI-FI on all the time.

Both phones are running Nogut 7.0.
[Samsung Galaxy S7 Real Life Review] Soufiansky:
Back to J7 2016 ? Just for a 20% increase in battery life ? There is no comparaison between the 2, s7 is a high end and still currently one of the best phones in the market.
[Samsung Galaxy S7 Real Life Review] salada2k:
Would be great if everyone could include:

SoT

Computer power use

Brightness setting

Thanks:)
[Samsung Galaxy S7 Real Life Review] barondebxl:
Looks like the Exynos version is kicking butt!!!
[Samsung Galaxy S7 Real Life Review] Occidental:
4 hours 25 seconds SOT 50% left

Easy 7-8 hours SOT with snapdragon 820

Snapdragon kicks ass, too. :)
[Samsung Galaxy S7 Real Life Review] jarayn:
The sad thing about society (or maybe it's just me) is that despite the fact I have no reason to think you might be lying or in fact that you would have any reason to do so. I still am assuming you are lying or at least fudging the figures by leaving the phone on the desk with the screen on lowest setting and otherwise not using it.

For every phone I have ever owned there's always a small group of people who report essentially double the battery life of every one else including tech review sites.

which means there's either a lot of real weirdos out there trying to get their jollies by lying about their phone battery life. (Unlikely) or there's some other factor I have never identified.
[Samsung Galaxy S7 Real Life Review] robertkoa:
That is encouraging.

Are you on LTE ?

I am hoping I could get SOT like this on Tmo Network ( Metro PCS ) on LTE at about 25% brightness with Sync OFF and Location mostly OFF ...

WiFi Screen On Times are not important to me because - if you have WiFi - you usually have Power Outlet nearby.

So please Post Brightness/ LTE

or WiFi /Sync On-Off/ Location On-Off / Exynos or Qualcomm

Thanks.
[Samsung Galaxy S7 Real Life Review] :
Yea, probably on LTE 30-40% of the day, rest on wifi.

I also used "package disabler pro" to disable anything I don't need. I keep screen on auto brightness unless I'm in a dark area then I manually turn it down. Fairly satisfied with battery life so far!

Sent from my Samsung GALAXY S7 Edge
[Samsung Galaxy S7 Real Life Review] daffie:
What factor...that you may be entirely wrong with your broad assumptions (...which is the mother of all.....well, you know) ? :p

Personally I'm on Exynos and get +7 hours of SoT. See my earlier post, with pics. A lot of other users have the same experience with their S7 (Exynos).
[Samsung Galaxy S7 Real Life Review] robertkoa:
Yes. Here is a copied excerpt from the Ars Technica Battery Stats on Exynos vs. Qualcomm 820 S7 and S7 Edge:

.

The surprise is that*the Exynos version does much better in our battery test, with both Exynos models having about 14 percent longer times in the browser test and a whopping 46 percent longer time in the more GPU-heavy WebGL test.*The caveat with these numbers is that we got the Exynos numbers from the team over at Ars UK, meaning the tests were run in different locations. So while the screen brightnesses were the same, these scores could be affected by external factors like ambient temperature, Wi-Fi, LTE signal strength, and more. On the surface, however,*it seems like the Exynos has the edge when it comes to power consumption.
[Samsung Galaxy S7 Real Life Review] beezar:
That caveat is a HUGE caveat which makes this comparison pretty much invalid. Signal strength is a big deal when it comes to battery life. I'm not saying that the Snapdragon version is not worse (which it probably is), but that this test is invalid.
[Samsung Galaxy S7 Real Life Review] vhc:
I noticed you posted a list of bloatware to remove using package disabler, do you think this would have a similar effect?

http://xdaforums.com/galaxy-s7/how-to/touchwiz-bloatware-save-to-remove-list-t3330241
[Samsung Galaxy S7 Real Life Review] xMinistro:
S7 flat.

SOT: 5hours with LTE sometimes on. 3-4hours with LTE all the time. We have crappy LTE here though so I guess it will get better if I just switch over to 3G only.

Currently disabled the Smart Alert right now. Let's see how it goes.
[Samsung Galaxy S7 Real Life Review] Lucoso46:
So guys: S7 Flat Exynos version is better?
[Samsung Galaxy S7 Real Life Review] robertkoa:
[MENTION=4318935]beezar[/MENTION] - yes true thanks for pointing out that the Snapdragon versus Exynos Battery Life Report on Ars Technica is not scientifically valid due to different Networks/Locations of each CPU/ Phone.

Are they on a tight budget and can not get both Versions in the same location at the same time ?

Apparently..

Maybe someone who has an International Unlocked S7 and a Carrier S7 USA will pop a SIM in the Exynos and give us some info .

Again - Tmobile has WiFi Calling and VoLTE so those can be turned off and will probably increase Battery Life ( also scanning for WiFi- OFF) - an International Unlocked Phone will probably not have these features and could skew the comparison results even on the same Network.

I am wild guessing on the same Network same usage a 10% or longer Battery Life with Exynos...

Battery Life is hard to compare BUT" Pro Reviewers" from large Sites who do phone giveaways so

have a few dollars often do full Reviews but don't quote screen on times...

Ideally a Site would have two Accounts on the same Carrier and

an Exynos and a Snapdragon and

Publish GSam Stats for a week...or some LTE Video and Browsing Tests on both Devices...

I am not impressed when a "Pro Reviewer" says

' I was able to make it through a full day at the office until 7 PM before needing the Charger and we ate Pizza'...lol.
[Samsung Galaxy S7 Real Life Review] Lucoso46:
Guys i think i will buy the s7 flat in the summer, hope give much better battery than s6.

S6 is average, better than my old nexus 5 but not too much.
[Samsung Galaxy S7 Real Life Review] Cryosx:
GSMArena also reporting similar results.
[Samsung Galaxy S7 Real Life Review] beezar:
Thanks for the heads up. Good comparison. It would be nice to know how the regular S7 Exynos vs. Snapdragon stack up as well, and if the Snapdragon S7 (not edge) would even have any sort of decent battery life.
[Samsung Galaxy S7 Real Life Review] _alex74_:
i don't understand your thoughts..... why someone will be lying or fudging? nothing to win or show off..... there's no price or smthg else.... we are here to show facts.... so you are free to believe or not..... but if you have some experience there are some apps that simply kills your battery..... even more on amoled displays white means pixels always on......

Regarding this, you can chat on inverted whatsapp twice more time than normal one using same battery.... but you will get twice display on time.....

then depends how you use your phone, if u connect phone to pc for a small amount of time, if u turn all off or use power saving or UPSM during night...

Now my third battery cycle:

- Exynos

- bluetooth always on and connected to my gear fit and sametime 3 hours a day on car audio

- data always on....wifi when i need to dl updates(then i forget it on ahahah)

- lot of chatting on inverted wapp and telegram,

- reading mails on inverted mail app

- half hours phone call

- small tasks you can do with your phone

- completely stock rom(not even debloated)

now, i never achieve those results on my S5 with new battery, completely inverted rom, totally debloated.

Who wins? not even one of us, but only our S7 which is the best upgrade i have ever thought...even from S5 which was perfect device.
[Samsung Galaxy S7 Real Life Review] Travis Bickle:
How did they get 13:32 hours SOT of web browsing with the s7 Edge? I don't think that's even possible.
[Samsung Galaxy S7 Real Life Review] soonpark:
So far so good

Pass 6hour sot
[Samsung Galaxy S7 Real Life Review] robertkoa:
They used a medium screen brightness all Remote Communications were OFF only on a WiFi Signal right next to the WiFi Source...

And probably a 'Web Script' which [ guessing here ] is less data intensive than typing and thousands of screen touches etc. which would occur in 13 hours of Web Browsing.

However IF you use low brightness and Airplane Mode or Wifi Only...you can browse a long time with a very strong WiFi signal especially with few background Apps etc.

Some People post Screen On Time and Battery Stats like it's a Contest...lol.

So they go 36 hours without a charge.

Since I am not a Vampire I sleep every night and can put my phone on a Charger...so I am more concerned with SOT during a 8 to 16 hour day( then charging) rather than going 36 hours to 40 hours with no charge.

And as I said- before I get a ' fixed battery' device I want to know what I will get..generally.

Also glass on BOTH sides of a Phone sounds fragile to me and the Edge sounds even more Fragile due to larger size and more exposed glass edges.

I prefer a small case like Casemate Naked on S7 with heavy glass screen protector IF I get S7...

But even S7 will be much more fragile than Alpha.
[Samsung Galaxy S7 Real Life Review] DSF:
Just 20%? Also, you missed the fact he said the phone was in standby for more than 3 days.

S7 has a pathetic battery life. Period.

But i have to recon that it's good for this winter, a perfect heating machine :)
