Can you tell me in detail how many apps you installed, dual sim? Power saving mode? AOD?

And using S health?

Attaching screen shots of battery stats, this is using power savings mode, everything is same as yesterday and surprisingly backup is same as yesterday, I hoped I would see good difference but no.
[Samsung Galaxy S7 Guides, News, & Discussion] Levan_i:
Not dual sim and not using S health. I am using debloated stock rom, have power saving on but with background network usage allowed and no speed limiter (I think this still saves some energy and also I don't like when navigation buttons light up). I don't use AOD, Bluetooth, NFC, Location, Nearby services etc. From the connections I only use WIFI/LTE (they are almost always on) with heavy or medium usage of web bowsing, FB messaging, Instagram and Youtube, and I got rid of Facebook app long time ago:)
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
I guess you have made many changes like debloated rom, Not using AOD, that's why you are getting pretty good backup. I don't use fb app either, but I use s-health, synch on so that must be it. If we limit these featured app, and they are kind of important for me then what's the use of advertising these features? We should get good battery life with all features.
[Samsung Galaxy S7 Guides, News, & Discussion] boydsc331:
is it possible that the phone and battery are getting older as time goes on and don't last quite as long as when it was new ?
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Offcourse it's possible, but it should not be drastical change. It happens because lack of optimization. My wife uses 2 n half year old Xiaomi Mi4, and it gives great battery backup and compared to that my s7 gives half of battery backup. Even previously I had Note 5 and it was the same issue. Samsung doesn't pay attention to these things once they release the new model.
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Or Samsung pays a lot of attention to these things when they release a new model so that you feel you need a new phone

Coincidence that ours phones suddenly lose 30% battery life when a new model arrives? Not really
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Yep, you are right. They do it deliberately, so people can buy their new release.but apple never do this, even after their new release, they pay lot of attention to their previous ones.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
I don't know how good is the fast charging for battery life. That makes the phone ultra hot.. and heat is not good for battery.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
It's normal getting phone hot while charging.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
Well, the s7 and s6 were the hottest phones while charging. And now i am using the oneplus 5 for a couple of months and i'm surprised how "cool" it is in comparison with my prev s7. It gets only a little warm while charging, even if you use the phone and abuse it (eg: download from playstore, update, etc). But it use different technique for fast charging, and you cannot quick charge with non proprietary QC chargers..

And Actually even while gaming this thing remain cool. :)

I've dumped my s7 because of mediocre battery life, heat even in simple tasks (i could fry eggs sometimes), bad ram management, glass back. This was the single solution i've found to "fix" the battery life.. oh well :rolleyes:
[Samsung Galaxy S7 Guides, News, & Discussion] difto:
Of course because Oneplus use dash charging which makes the final voltage conversion inside the charger instead of inside the phone thus less heat. Fast charging is not fast on the S7 and it slows down as soon as the battery reaches 35C which is pretty low.

The S7 has a lot of bloatware which makes the battery life quite poor. Once those are disabled battery life is good. I usually get 6-7h of SOT
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
Yeah, but the s7 gets hot even when using it normally (i had the exynos for 1+ year). I couldn't stand this issue. But in winter this may be a good thing :D
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
I don't find my s7 that much hot, and like frying egg hot, not at all. Ram management is good after updates, but I agree it's still laggy and can't compare with one plus. The reason I cannot choose one plus or another phone is display & camera. No display comes close to samsung's display & aufocus like s7!
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Only heat I get from my S7 is from fast charging and from GearVR use, stays cool for everything else
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
Well mine got hot extremely easy (exynos variant again), but back then it was sunmer (so the ambient temperature matters too).

I was very frustrated about losing my apps state after using for eg Facebook a bit.

Overall, the camera on one plus is not that bad too, but still not great. But i've been impressed with some portrait shoots. Anyway i was not too impressed about s7 camera too, most of my shoots were out of focus ans blurry when the light was not perfect. The autofocus is top notch on s7 dou', the fastest i ever seen!

And about the display, for me it's a no issue, since i've already been using full hd on the s7.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Yes same here. Well as I mentioned earlier I get very bad battery backup but I use s health and and many apps too, maybe thats the issue. Have you used debloater? If yes can you or anyone else tell me which system apps would I debloat other than s health?
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
I don't debloat, not rooted, I use a package disabler to disable any system apps I don't use
[Samsung Galaxy S7 Guides, News, & Discussion] fracarol:
My s7 does not heat up only now (in winter) when at home I have +/- 20°C and outside it's below 10. When it's hotter outside (so that heat can't dissipate from the phone to environment) it clearly needs a fan to keep decent temperatures.

Anyway (also probably because of note7) Samsung extended the life of its batteries with S8 so they should last longer in years, so no more conspiration theories about batteries at least on S8. The more you use android the more what you keep on your device will absorb energy, if android is not optimized (actually since more or less lollipop touchwiz ROMs I guess). 7.1.1 and Oreo should change things about optimization on touchwiz so we'll wait some ages for the update then we'll see
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Samsung doesn't learn, they only showoff in device launch and spend millions in marketing. But battery optimization is not their concern, even brands like xiaomi and one plus does way better in this area. It it wasn't for camera I'd never buy samsung.

Any specific system apps are there which will crash system if I disable them?
[Samsung Galaxy S7 Guides, News, & Discussion] Levan_i:
Which version do you have, US or exinos? And what firmware are you using? 6-7h is almost twice as much as my SOT despite of the fact that I have custom stock rom with 120 apps removed and 20+ apps disabled manually by package disabler pro.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Disabled many system apps, but draining battery as usual. Let's see, will update stats.

*within one hr lost 20%.attaching usage stats, can anyone tell me which of these services can I disable?
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Here are the usage stats
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
** just noticed, many of these services, I disabled them, still they are running. Why??
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Where does it say they are running? That list just shows included services inside the Android System
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
LOL, I thought they are running.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Here you can see android system consumed battery and if I expand android system then it showed all those services, so those services are running or not?
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Not if you disabled them and rebooted no.

You'd need some sort of task manager to view what was running in real time
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
No task manager gives in detail unless we have root. Any way to disable backlight of back /multi-tasking button?

Edit: nevermind, installed app to disable backlight.

[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
I am also facing same issue, you can see my battery stats post above yours. Battery has a warranty of 6 months only, so if it's passed 6 months then samsung won't replace battery for few. You cannot use s8's battery to s7, even if it fits its not calibrated for s7. I am also trying to figure out why I am getting so bad battery backup. I'll post here if I find the problem. Don't trust on accu battery. Post your battery stats here, from 100% to 5%.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
No, it's because new software updates, and apps. My wife has old mi4 and it's giving same backup as it was in beginning. Samsung sucks.
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
100% a software issue, nearly everyone lost around 30% capacity from the May security patch onwards, and it's never got any better with any updates since
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
How is ur mobile network? If your network is not good then also you face battery drain issue. If device is rooted then we can know what's exactly causing battery drains by using betterbatterystats, but I cannot root as I love using Samsung pay.

Bad battery life on s7 g930f

Hey guys, i got the galaxy s7 two weeks ago, and i'm experiencing a really bad battery life.

I dont play much with the phone, but damn its bad. I had the lg g3 before this phone, and my 3 years old g3 beats it all day in the battery territory.

Can you help me out with this? What should i do? The device is 1 year old. Got all the updates, i even disabled samsung health and some other apps to gain battery life, but no help there. On 15% i get max 3hrs of SOT, and that happens if i dont play games, use too much of facebook, viber and other stuff, but whats the point of having a smartphone of this kind and not using all those apps? Im desperate, help me!
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
You got 11 hrs of standby with 50% remaining & 1.5hrs sot, I'll say it's a great battery backup you are getting. Most of people here including me get 8 hrs of standby and 3-4 hrs of sot.

Check how is your mobile phone network. Install betterbatterystats with adb, find instructions in above posts, then you will know what exactly hogging your battery.

** fb app consumes lot of data, hence battery.
[Samsung Galaxy S7 Guides, News, & Discussion] tomykc:
When im at work 3g network is on, when im at home i turn off 3g and put wifi on.

What do you mean with great battery backup?

[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Something is preventing the phone going into deep sleep, and that call recorder looks like it's got quite a lot to do with it

The phone says it is staying awake even with the screen off, apps are generally the cause

You need to troubleshoot this with a clean flash / factory reset, not with an old install full of dodgy apps where anything could be doing it
[Samsung Galaxy S7 Guides, News, & Discussion] fracarol:
Just go to settings - developer options - running services

There you can find what you really have to deactivate, no need of root task manager etc I think

Maybe you can try "force doze" app on play store (requires some simple ADB lines but worth it)
[Samsung Galaxy S7 Guides, News, & Discussion] audianer:
For all with battery problems:

Check your battery health!

Download an file explorer like "es file explorer" and go to /sys/class/power-supply/battery. There is a file named "fg_asoc" the value is your battery health in prozent.

The health of my battery after an year was only 68%. New battery and my phone gots DOT 5h again.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
I guess you need root access to check this. Coz I cannot find the folder you mentioned.
[Samsung Galaxy S7 Guides, News, & Discussion] insang-droid:
Well I ended the night at 1am with 7hours SOT and 14% left. It's definitely better than any phone as far as SOT goes, but I hope the update fixes the Google service drain. It's absolutely crazy that it's draining more than 6 hours of screen.
[Samsung Galaxy S7 Guides, News, & Discussion] johanbiff:
that is really bad acctualy, my S6 with 1year old battery looses 2% over 8h sleep with wifi on..and it only have a 2550mAh battery..something is deff wrong here..
[Samsung Galaxy S7 Guides, News, & Discussion] hung2900:
Which variant do you have? It seems that the Exynos version has superior battery life.

Btw, there is a source said the S820 version throttled.

[Samsung Galaxy S7 Guides, News, & Discussion] jamesskinner97:
Left it overnight on 48% at 11PM, woke up at 8AM with 33%. I left it on Always on Screen. It has drained more than expected, I thought Android Doze would have helped, but it is just as bad as my S6. Hope update fixes
[Samsung Galaxy S7 Guides, News, & Discussion] stierney:
Got mine direct from Samsung UK. 2 days use. No battery drain issues here. This must be carrier branded firmware or bloat causing issues?

Weird '10239' draining my battery

I have experienced very poor battery life so far, generally it has been the Android system that is the culprit but today something weird... something called 10239 is draining my battery more than the Android system, any ideas what 10239 is (I definitely dont have an App installed called that)?
[Samsung Galaxy S7 Guides, News, & Discussion] Synyster06Gates:
Android System is eating up about 50% of my battery on a daily basis. Hopefully there's an explanation/fix soon.
[Samsung Galaxy S7 Guides, News, & Discussion] iamnotkurtcobain:
Guys just some thoughts.

You say the Europe Exynos models have not the Android System drain.

What if the reason for this is that they DON'T have the Verizon, At&t, Sprint, Tmobile bloat on it??

Could be the reason.

There is drain on my Exynos only on mobile data though. Android OS is always on top of the list. Standby time is bad too, down 3% every hour. On WiFi, it's under 1%
[Samsung Galaxy S7 Guides, News, & Discussion] iamnotkurtcobain:
I have that drain on my S5 with cm13 and on my S4 with cm13 too.

It's still the old bug from Lollipop.

Guess we have to wait for Android N....

That sounds too good to be true :p . Can you tell us how you were using your phone ? (Games, browsing, movies WiFi/LTE etc.) Also it would be great if you could post screenshots when it goes down to 15%.

They don't work, they cannot accurately measure a batteries capacity, it has been discussed many times on XDA in the past

And 68% capacity remaining after 1 year of use is a joke, I'd expect that after 3-4 years, maybe longer

I've got a new battery from Samsung for warranty because the battery performance had dropped significantly.

The value auf the file before was 68 and now 96. Before about 3h DOT and now 4-5h DOT.
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
If those values are correct then how come your brand new battery shows 96?

Anyway I tried, mine showing 83.Though I don't trust these values.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
[MENTION=5504716]nvrmndryo[/MENTION] that excelliance multiple accounts app seems to wakeup the phone a lot. Also the recording app. If you can uninstall those apps and see how it goes.

Ps: i am using ACR for recording, and i find it very good.
[Samsung Galaxy S7 Guides, News, & Discussion] audianer:
My battery is now about 8 weeks old. On the first day it shows 98.

I know that the values are not accurate, but it is a clue.

I only want to help people how dont know why there drive only got 2-3h DOT.

If the values is under 70, you know that your battery is bad....
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
So 2 months = 2% drop, which means 12 months = 12% drop, yet your old battery lost 32% in 12 months.... and you think those capacity apps work?

They don't
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Yes, my recording app is always on in background, but I don't think ACR will make any difference, call recorder I m using has 100 million downloads.

btw have u checked in betterbatterystats if ur ACR is awake all the time?

---------- Post added at 06:19 PM ---------- Previous post was at 06:16 PM ----------

Yes, it's got nothing to do with battery, it's our apps, those are draining battery because doze is not working as it should. With same apps installed on other phones like moto g5+, mi4 give good battery backup. Blame is to samsung. But we have to figure out solution. I am using greenify now, but didn't see much improvement. Will share stats later.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
[MENTION=5504716]nvrmndryo[/MENTION] just checked and i haven't seen ACR in partial wakelocks. (22h since unplugged)
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Cool, i might give a try then. Btw wt are ur 100 - 0% stats?
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
No problem. Sorry, but i don't have the s7 anymore, but i think i had about 2 SOT in about 24h, ~95% wifi 5% mobile data. And about 4-6h SOT "almost straight" only wifi and no commute.

I solved this issue by switching to oneplus 5 heheh.

(Ss are for no commute, wifi always on)
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
You are getting 8hr sot on op5? Wow! How many apps you have installed?
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
I can get more if i use it more than leaving it in standby :D. But again, this is wih no commute.

If commute/in move i get maybe about 5-6h SOT in 24h, 95% wifi 5% mobile data (i have google fit and google maps timeline enabled)
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
That's Gr8 sot if it includes gaming, watching movies, YouTube usually gives more sot.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
I rarely game. Most of the stuff is chrome browsing, YouTube, facebook, instagram, twitter.

Anyway, I don't wanna hijack this thread, but trust me i was so frustrated with the battery life and the heat of the s7 (also s6 edge, both exynos).. and now i can say there is no comparison regarding those! And also the pure android look is a big bonus for me.

But i can understand that for others things like water resistance or microsd support are dealbreakers.

Sorry for going offtopic :D, but sometimes you solve a problem by switching/looking to something else!
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
Yes I know how frustrating this is, I thought many times of switching to other brands, but I cannot let go of samsung camera. But good to know.

** I forgot to mention this,

Last night I slept while watching YouTube on my phone, I must have got up after few hours, I touched my phone it was still running YouTube, and it was literally boiling hot, previously I had note 5 & I used to watch YouTube all night but phone never got this hot.

This is the second time my s7 got this hot, anyone facing same issue? Or what could be the issue? How can I find out if my phone is faulty or not?
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
You can check via betterbatterystats which process took the most. Maybe something went crazy. However mine was getting hot even when watching youtube videos (1080p), so it may be normal to heat up to some degree. Mine was hot most of the times, literally :)

(Chrome, YouTube, whatever i've used.. on wifi

Because on data, i could fry eggs all the time.)
[Samsung Galaxy S7 Guides, News, & Discussion] fracarol:
Maybe it's just because of the surface where you left your phone, I noticed that if you leave it on a sofa or on a pillow it won't dissipate heat and get much hotter than if you keep with your hands or on a wooden table etc (so more airy conditions or colder materials). S7 gets easily hot
[Samsung Galaxy S7 Guides, News, & Discussion] nvrmndryo:
It's was on my bed.
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
bed = insulation (Designed to keep a person warm)

Keep phones off things like that or they will overheat (If being used heavily, like watching video or playing games or being charged, anything that causes the phone to heat up)

IIRC someone set fire to their bed charging an iPhone overnight while the phone was on the pillow or bed
