I've bought the international version of the S7 (the only one available here in Portugal) which is the SM-930F on the last tuestday (2016-09-16).
During the wednesday, I've noticed that the battery drained really fast, but I thought that it was because of the whole first-day configuration / installing 50 apps thing.
On thursday (yesterday), I removed it from the charger at 8h30, barely used it, and at around 13h00 it had 44% battery. I don't have a lot of background syncing or anything like that, just the normal I've used on other phones before the S7.
I've read somewhere from people that had similar problems and they said a factory reset solved. I did a factory reset but the battery kept draining at the same rate.
So, at around 20h30 I went to the store and asked for a replacement. Exactly the same model and color.
I went home, installed all apps and updated everything so I could test it today without updates and downloads. I didn't restore any settings from previous installations.
Today I took it off from the charger again at around 9h00, it's 14h30 and it has 64% and I barely touched it! I've checked some stuff at lunch time for like 10min, that's all.
What can possibly be wrong here? Everyone on the internet says that this phone's battery life is one of the best out there, but it's draining faster than any of my previous phones!
Both the original and replacement phones were sealed in the box.
Any ideas?

Hi
Most of times battery consumption is due to settings , WIFI , e-mail sync , location , rogue app , facebook..... review them......maybe do a factory reset , install nothing and see how it behaves , install app in smaller lots to see if there an increase on battery drainage , if you where root there is an app that is great to see exactly who is the culprit

If it was a rogue app, wouldn't that show up in battery usage?
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
The only thing I didn't have in those phones was the "screen always on" of the S7 that shows the time, which reviewers say that it's so optimized that it barely makes a difference.
I wouldn't be complaining if it were draining a bit faster than the Note 4 or the old LG G2, but it's actually draining like 4-5 times faster!
Yesterday I had both the G2 and the S7 with me, with all the same apps, with a SIM card from the same network/account.
When I reached the store, the S7 had almost critical battery, while the G2 had around 80%...
The S7 didn't get hot or anything.
I will wait a couple days to see if it improves, but it's extremely disappointing, after spending 730€ on a new phone (around $820).

Battery drainage is a Bit** , some time is hard to find out what is going on and you need to be patient and methodical
to your questions
If it was a rogue app, wouldn't that show up in battery usage?
Not necessary , may be is a process and do not show in there , most times you need a better app (BBS the link i gave you) and be root to see those process , or by discarding apps to find out
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Different phones , not necessarily the apps behave the same in different phones
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
Try different settings and see if they make a difference , see what apps are using location , do not have wifi on all the time during sleep......
In my case i do not have even half of that drainage , of course we all use the phone in different ways and have different apps......as i said is a royal pain in the a** and need to be patient and methodical to find out if is a real hardware problem or a configuration problem
After reading this,
https://www.reddit.com/r/GalaxyS7/c..._s7_edge_battery_drains_20_overnight_8_hours/
I've decided to wait for a few days to see if it improves. The poster seemed to have the same problem I have and he said it stabilized after a few days.
If he problem persists, I will try the things you said.
Thank you.
Maybe you can install Better Battery Stats and wait for it to give you some answers.
I would suspect that the phone has trouble connecting to network, WiFi or mobile network or tries to constantly fix to gps signals. A constant search for better connection results problems like yours. If you can, try another operator sim for a day, or try another location.
Perhaps do not use wifi for a day to rule out bad compatibility with your routers settings.
My S7 SM-930F do not lose ever one percent per hour if left unused with everything on and no powersaving.
Did you use Memory card ? I had similar issue on S4. There was damaged file and phone tried read it whole time.
I had the similar problem which was caused by Email App. Try to install Wakelock Detector Lite and see which app drains the battery most. In my case, Email app was preventing phone to enter deep sleep mode and it can not be seen in Android battery statistics.
Wakelock Detector does not need root but you need to enable developer mode and use adb shell. Code is below, you can Google it for how to.
Code:
"adb -d shell pm grant com.uzumapps.wakelockdetector.noroot android.permission.BATTERY_STATS"
Here's an update:
So I've waited a couple days and the battery seems perfect now. I've unplugged it yesterday at around 12h30, used 9gag, browser, facebook, youtube, gmail (a bit of everything, actually) and now it's almost 10h00 and it still has 44%.
I've installed that GSam app and it seems that the phone was transferring lots of stuff through WiFi in the first 2 days, I assume that was the cause.
Thanks everyone for the tips!

Thank you for reporting back on how this went for you! Not everyone is so good at doing us this favour!
A lot is going on with a newly initiated mobile and perhaps it was a new firmware too that was downloading in the first days and together with everything else the battery life seems terrible to start with. My S7 downloaded a new firmware and flashed it in my first few hours with the phone and I didn’t notice before it wanted to reboot to flash. Together with all other updating going on if you reinstall apps and set things up it takes a while for the poor thing to settle!
The switching of phones did of course make the whole process start from scratch again and this made the problem seem even worse to you!
Well, Samsung should put some kind of warning in the box or something, I was getting extremely disappointed. I'm very happy now though, the phone seems to be amazing.

Hi,
I've got an HTC One S since a few weeks (got it with the 1.57 FW I think). It's a stock one, not from a carrier. No branding.
The battery life was great, 2 to 3 days with normal use.
But yesterday evening I proceeded to the OTA update and since then, trouble began
Battery life is much, much lower. After 12 hours standing on my desk in the office, I got 10% remaining!
Anytime I switch the screen ON, I see there is some data being sent (or received) because the "arrows" are full. If I check in system panel lite, there's always 1 or 2 kb/s of traffic.
Also, the phone is a bit warm, quite often.
Has anyone else noticed this? That's rather annoying :/
Could be faulty? I have the same phone with no carrier or branding and not had any problems at all.
Like faulty hardware? Seems unlikely to me since it worked well with 1.57. Also, sending data isn't hardware related
Here are some details.
In Mobile usage, just for today (less than 24h)
"Media" has used 13MB of background data
"Android OS" has used 5MB, also background
Android OS gives no more details. Media is told to include "Download manager" "DRM protected content storage" "Media storage" and "Downloads"
This sounds like a lot of background data :/
Try an app called Badass Battery monitor. It should tell you what's eating your battery.

I have to say, this phone, at least mines, seems to have a pretty bi polar battery. It's got a case of ADHD.
For example, just the other day, I had the phone fully charged when I awoke at 9am, after playing Temple Run, surfing the web, using GPS, streaming and listening to music, playing more Temple Run, fiddling around with the OS, checking emails, sending texts, talking on the phone a bit, downloading apps, with about 25-30% brightness, I ended up with 18% battery remaining after a good 11 hours of very heavy use. I was quite pleased, considering the inordinate amount of usage I had with the phone all day.
(BTW, I use Juice Defender, which has helped tons in reducing battery drainage for almost every phone I've owned in the past 3 months, including the One S)
Yesterday, I had the phone charged at 100% when I awoke at 9am, with a little bit of use, by 12am, I had 63% remaining, same brightness, but with much much less use then the day prior. By the time 3pm hit, I was at about 30%, and by 5pm, it was drained to 18%, mostly on standby. By my estimation, that's 8 hours of usage, same brightness levels as the day before, using Juice Defender, but with much much less fiddling around with pretty much everything on the device.
I went ahead and disabled Juice Defender today to see if it would make a difference, and the battery actually got a bit worse, so I went ahead and re-enabled it and it immediately improved.
So I'm a bit perplexed, I haven't gotten any official updates, still running on the original stock build, but ultimately, I guess this is what is too be expected with an early build. Hopefully future updates WILL fix these issues and not hinder them more. Granted it's still much better then my HTC Amaze and Galaxy Nexus, which drained 4% the moment I took them off charger.
Thanks for your input, I'll check again today how the phone goes.
I played with all the settings and menus yesterday, and found something strange. In the "downloads" app, there was a "system update" download. That's quite normal since I downloaded and applied the OTA the day before. But it was referred as "ongoing", like it was still downloading a part of the OTA zip file AFTER I applied it (and rebooted a couple of times)
In phone settings, about, updates, it was also written "ongoing"
Now this is over (I don't know why and how) and the network usage seems back to normal. I'll try today to see how the battery drain is
Anyway, it's s strange the phone was still downloading the update zip file after having applied it. AND that it was downloading it on the 3G at a very lowered bitrate (like background) while I downloaded it on the wifi the day before
Anyway...
The battery life of my One S seems to have declined as well since the update. Before the update my battery lasted 2 days easily with moderate usage. Now I have 20-30% left at the end of the day from a full charge since 9am. This is with very light usage (mostly on standby from 9 to 5).
I did turn on best wifi performance recently so I just to turned that off to see if it helps but I really doubt that.
Hello guys, I have same problem, but my phone wasting energy on "phone radio" process, just look at screens below. I tried using stock Rom with last update, trickdroid, and now it happend on leedroid v.2 . Btw I changed 4 micro sim cards with several providers, but no result. I really need help with this issue, because my battery draining very very
fast...
Thank you

I had a similar problem a few days ago, using Lee´s ROM.
I noticed that the drain had something to do with autosync. As soon as I turned off autosync (leaving mobile internet on) drainage went back to normal.
I still don´t know what caused this since I only had the google account, weather and dropbox installed.
Anyway, after doing a fresh install, the problems seem to have gone.
Of course I can´t be completely certain of it until some more days of testing/usage.
I also noticed quite a few problems since the latest OTA update.
Not only does the battery drain fast, the phone also feels extremely hot when browsing on 3G.
The phone does cool down pretty quickly when turning off 3G but it feels like I burned my hands
Here are a few screenshots.

I also experienced weird things when connected to EDGE (2.75G).
3G (HSPA) coverage on BASE (KPN) sucks in Belgium
Look at the video below for more details.
Has anyone else experienced this yet?
http://youtu.be/3g8FLpWDAYM
I also contacted HTC about this issue and they recommended a hard reset.
Unfortunately this doesn't help at all, I still get these weird glitches
mattionline, can you get a logcat when the phone's doing this weird stuff? It looks like the Home button is being pressed repeatedly and if logcat confirms it then it's probably a hardware problem.

Do you need root to make a logcat ? My phone is not rooted and I'm not planning to do it. How can this be a hardware problem ? I never had this problem before. I'm sure that it's a software bug.

I just fixed someone else phone that had the exact same symptoms. In the end I narrowed down the problem to one of his weather apps.
He had a live wallpaper that reflected the current weather, weather on his lock screen and a beautiful widgets weather thing. I never did figure out exactly which one it was I just turned off all there and told him he was crazy.
I don't know if it's something "weather" related for you but it maybe it will help.

you don't need root, just enable usb debugging in development options and connect the phone to your pc. You need to have the android sdk installed.
Sup guys , some of you don't seem to realize that there are many reasons why your battery drains, what you might think is, "quickly". A few tips to keep minimal battery out put...1 keep brightness down, the screen itself sucks juice probably the most. 2 check your apps, some apps send and receive data and/or are kept running in the background. You might have to enable/disable setting on shove apps. 3 widgets, widgets like battery meters, CPU meters, things like this constantly refresh to keep real time info. That also eats up alot of juice . 4 Turn off WiFi or any other thing like that when your not using it. WiFi continually sucks nice. Lastly, invest in some app that will help you close apps. Basically, tweek everything you might think that the os can run without. The less your CPU has to do, the more juce you save.

This made me lol hard.
Best advice ever.
But yeah, on the 1.0 version of Leedroid I had quite some drain, too.
When I turned off autosync it went back to normale. I only had my google account, dropbox (with syncing off) and the weather thingy set up and never figured out which one was resposible.
After installing Lee´s 2.0 ROM everything is fine.
I suppose there really is something wrong with the autosync and maybe with the weather stuff in particular.
My problem didn't go away with stopping auto sync, even without it, I had a constant data flow
Anyway, I rebooted the phone twice and the issue was gone.
It happened again a few days later, after the phone did shut down because of low battery. I put it on charger and turned it on, then, I noticed the 3G arrows were always on. After I unplugged it from the charger the battery went down in 10 hours. After a reboot, problem gone...
Since then, nothing...
And please note than when the problem is here, it's media and android os using a lot of data
I have been having one S problems too - I am on my second phone after the first one became reliably unresponsive every time I turned on mobile data. More relevant to this discussion, my battery died shockingly last night. Normally it drains at a few percent an hour when I am not using it (i.e. when asleep!) but I woke this morning to find it totally dead - that is 30% plus gone in 5 hours without it being in use.
Ok so i've seen a few threads between here and other websites regarding the Note 3s battery issues but felt the need to make my own as I still haven't found any kind of solution.
I purchased my Note 3 N9005 (I live in the UK) around a month ago and ever since my battery has been terrible ever since. I am basing this on the fact that I have owned a Note 3 twice previously (I managed to get one just after they came out for a reasonable price second hand and also owned one around 6 months ago for a while) and battery life on those two devices were fantastic.
Around a week and a half ago I decided to root and try a couple of roms to see if it would make any difference after making sure it wasn't my SD card causing the problem and couldn't really try anything else. After going from the CMRemix, CM11 and Echoe 5.0 not a great deal changed on each after using each one for a couple of days, every day my battery gets hammered by 'android system' and 'android os'. After seeing a post about it I have gone back to stock touchwiz using the 4.4.2 Nordic firmware. This made no difference either.
I have posted some pictures of my battery life since getting up this morning. I always have sync turned off and my screen is always just above the minimum brightness. Im on Wifi a lot between work and home which in theory should use less power. I've been playing contest of champions quite a bit recently which I would expect to be a battery drainer but it is still beaten by my screen and this android system and OS combo. I also don't get why battery dropped around 18% (30 something to the 15% warning) in around 20 minutes which is the red line on the battery graph. Last Friday I went to sleep with my battery on around 78%, when I woke up it had dropped to 42% with no apps left running.
I'm literally out of ideas. I've tried everything i've seen on forums and it hasn't worked. I've owned an S5, m8 and z2 but ended up coming back to a note because they are simply fantastic phones. I am however seriously considering selling this and getting a different phone if I don't figure this out soon though. Can anyone help or is this simply an unsolvable problem caused by horrendous software implementation, or am I being stupid and should be content with 13 hours irregular battery life???

Thats just not normal, try to use app wakelock detector (from playstore) to see what apps are currently running, you can also go to the device app manager and then go to "running apps" and then see what apps are running on backround, that would give you a general idea of where are the battery draining apps. Then all you have to do is to disable/freeze them , using the inbuilt disable option under the app settings or using a third party program like app quarantine (from playstore). Note that i also recommend you disabling apps you dont use , like for example samsung apps etc.

Thanks for the advice. I even ordered a new battery from samsung which arrived this morning but that doesn't seem to have made much difference either. If I hadn't seen similar cases to mine i'd think my phone was broken but honestly I'm starting to think that is down to samsung software and won't ever be fixed. It's a shame because the Note 3 is the best phone i've owned but ill be steering clear of samsung devices in the future

Use Greenify to hibernate apps..it will save ur battery..
Greenify is a big help. Also use Titanium Backup to freeze or uninstall anything with the word 'Samsung' in it that you don't need (they're terrible, in my experience).
Some other things that can help are turning off GPS and Bluetooth when you don't need them, raising your wi-fi scan interval if you typically leave wi-fi on in areas you're not connected, using an app like AutoStarts to control what apps wake up when, and you should check what apps you have auto-syncing, and how often. If you don't need gmail and facebook to sync every 5 minutes (just an example), then change the interval. And unless you spent a good bit of time playing it before you took those screenshots, I would highly recommend ditching that Champions game.
Aside from that, another thing you might want to consider is trying a different kernel. Some kernels are just bad on battery life.
I'm on my original, stock battery, and I get 22-26 hours typically, with moderate usage, and anywhere from 6-10+ hours of screen on time. Right now I'm sitting at 18h5m29s with 5h26m3s screen on, with 27% battery left.

Trying a custom kernel is something else I'd though about. It's crazy that you've got those battery stats. My brightness is always near minimum and I only get 4 hours on a good day. Judging from posts I've read those android os and system percentages are accurate for the note 3 nowadays. I never have sync turned on so that can't be the issue. I've got this phone on ebay now so if I don't sort this out in the next couple of days I'll be moving on unfortunately, bit sad as this is the best phone I've owned

I'm in the same boat. Stock 4.3 with tons of apps frozen, greenify doing its thing and Google Play Services tamed as it was draining the battery. To me everything looks ok in WLD but I have noticed that something called 1013 which is always at the top with most amount of wakes, is that system audio? I also have screen brightness on minimum, powersaving mode on, bluetooth and gps off, sync on and most of the time usually on wifi networks.
I have managed 6hrs screen on before but when using device moderately over 2 days I get 4 hrs screen on time at best, usually 3 or 2.5 hrs.
The 6 hrs was managed when I watched 3 movies in a row, it seems sleep takes more than it should? Wake ups are a problem?

Yeah something has definitely gone wrong at the core of the phones software, especially when different roms and stock firmware builds are making no difference at all. I flashed AEL kernel yesterday so i'm seeing how that goes today. I'll post screenshots when i get home from work, so far my batteries only dropped 10% in 3 hours but thats with 30mins screen on time.
Had similar battery draining issues, I froze Unified Daemon (EUR) this appears to have fixed it.
I have faced this issue after my phone got the last update.
Even the android system was consuming more than the screen.
I removed Google account and put it back again but this time i limited the Google features that do the sync to the required only, gave a full recharge, the second day the android system consumption decrease a bit.
I gave it a full recharge cycle each day for the next 3 days and later it came back to normal.
I hope that helps.

I had the same problem. for months and no solution anywhere. what I did was to downgrade back to jellybean. this is the only thing that seemed to stop the drain. though I still believe my battery was much better on the initial jellybean.

Hi guys. I just created an account to these forums. I've used them before when rooting a previous phone. I have a problem with my new S6. I got it about three weeks ago, and I love it. The only problem I have is the incredibly short battery life. There has to be a problem with my phone, because I'll have a battery life of about 5 hours on a good day, but usually 2 or 3. The phone will get mildly hot, and all battery will drain rapidly. I will regularly lose ~40-50% in an hour after it starts heating up. I've been simply dealing with it for a while, after a failed attempt to find a solution on Google. I regularly close my apps, and I even have powersaver on at all times now. Last night, I closed all apps, then restarted my phone. It was at 98 when I fell asleep. I woke up 9 hours later and it was dead. I have checked the battery info a couple times, but I don't ever see anything rapidly draining battery. Could this be a hardware problem?
I have a Verizon S6 regular. Model number SM-G920V
Try to calibrate your battery first.
I suggest reinstalling the software using Samsung's smart manager and updating to 5.1.1, I never had your issues but noticed a big improvement with battery life. I'm sure you have a rogue app somewhere running havoc. There's also a lot of things you can do to improve battery life after reset, like disabling background data on certain apps that you need need constantly connecting and using data like Facebook when it's not even in use. Just play around with your phone to know the ins and outs

Thanks for the suggestion. Where is the Smart Manager? I Googled it, and found a thread saying
It is included on the phone, however there is no way to access it that I've found. You can find it under Application Manager - ALL. Scroll down to Smart Manager and select it, you will find that the app is running but we are cannot access it and the DISABLE button is grayed out. My guess is that Verizon wants us to use their My Verizon Mobile app instead of Smart Manager. I heard that AT&T did the same thing.

I suggest wiping the cache. I was experiencing a similar issue. After wiping the cache, consumption return to normal.

98% gone during 9 hours of sleeping? wow...
1) Do the factory reset, full wipe and see if its gonna get any better.
2) If still the same problem, then download latest firmware for your model from sammobile.com http://www.sammobile.com/firmwares/database/SM-G920V/ and flash it via Odin / Download mode
If still the same issue, then contact samsung for the warranty :X

You might try a Sprint fix since your Verizon S6 has CDMA too. Since you've got a Verizon phone, this setting may be somewhat different. On my Sprint S6, I changed the setting under 'Mobile Network', then 'Network Mode' to LTE/CDMA' instead of 'Automatic'. That made my battery life much better. I think I remember a friend with a Verizon S6 and it had 'Global' instead of 'Automatic'. So change it out of 'Global' mode and see what happens.
Before anyone asks I have searched, Googled, looked on reddit, and gone through these guides on xda:

I have a Galaxy S6 fro Rogers in Canada (no root) and I recently updated from 5.0.2 to 5.1.1 and my battery life has gone to crap, my usage patterns and apps remain the same as before. Previously I would get about 4 hours SoT, 5 on a good day. Now I can barely get 2.5 hours SoT. I have no other problems with this phone, none of the RAM issues, lagging, or over heating other people have mentioned, my only problem is the poor battery life.
The apps are primarily use are Facebook, Puzzle and Dragons, Messenger, and Chrome, I realise that these are battery guzzlers but 2.5 hours is ridiculous and I used to get more using the same apps. I typically start using my phone around 8am from 100%, and by 5pm after 2.5 hours SoT it is around 20% battery life, previously it would hit 20% around 11pm with about 4 hours SoT. No apps are draining a particularly large amount according to GSAM.
To reiterate the things I have done to improve my battery life are:
1. disabling unused apps in application manager
2. setting brightness to lowest setting on auto
3. restarting phone
4. restarting phone in safemode
5. clearing cache
6. performing a factory reset after updating to 5.1.1
7. leaving wifi gps off when not in use (but I'm not constantly turning it on and off either)
8. Greenifying apps I use less than once a day (but anything with push notifications is not Greenified)
Additionally I have not moved or anything and reception in my area has always been decent. Any suggestions for what else I should do? My phone is still under warranty, should I send it to a service centre? Or should I try rooting it an actually deleting bloatware and having an ad blocker (though this would void the warranty...).
Please advise! I am very frustrated with this battery life.
Im having the same issue after updating the GS6 on Wind (Canada) to 5.1.1. Terrible battery life and Android OS draining battery as well. I barely get 2.5 SoT.
I'll join this unfortunate crew. I have to charge everyday before leaving work in order to get through the day.
Take off the charger at home when I leave and by the time I get to work(30-40 min drive) I'm at ~95%. By lunch I'm down to around 50%.
Hoping Android M fixes some issues
Clear cache in storage option and reboot! It will very slightly improve!

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Android/thread-id/31962/page/32 Read through the last 6 or 8 pages over there. A lot of unhappy people with Rogers right now using the S6. I'm in the same boat. Crappy cell service, times it will show bars of 4G but then tell me there is no network connection. Try to make a call with full bars at 4G and it will say not registered on network. Text messages being sent and received twice automatically. No connection at all in places my HTC used to have 4G if not LTE. I had to send my S6 away for camera repair for a week so I pulled back out my old HTC M8 for that time and my connection was stable and awesome everywhere just like I thought it should be. Now that I'm back on my S6 it's barely hanging onto EDGE in places I had full 4G bars on the HTC like at my desk at work. Places I spend a lot of time at.
I suggest you call Rogers and talk to the tech support. Tell them your issues. The more complaints the faster the issue will be resolved. It sounds wide spread so don't waste your time trying to fix it yourself.

Thanks for the link, I didn't think to check the Rogers forums, I'll call their tech support to let them know of my issues and hope they are working on something.
I also have this issue. I was able to make it through an 8hr work day before the update. Now it's down to 10% or to completely dead. My usage at work did not change. Sucks that I have to plug my phone into my car just to get enough juice to make the drive home.
Just to confirm are you guys all now on 5.1.1 and is battery life the only issue you are experiencing?
I talked to a rep with my carrier (Rogers) and he said that the known issues were to do with connectivity (calls, data), but not with battery. He said battery issues that could not be resolved by a reset should sent in for service.

There was some discussion in various places about cell standby being a HUGE drain on the battery when connected to WIFI.
My issues are data and call related. I've never been one to care that much about battery but it does seem off from what I'm used too and I'm seeing some long times on the mobile radio being active.
I think it's safe to say that all of this stems for the 5.1.1 update. Cell reception "problems" can lead to big battery drains and if our phones are having issues staying in tune with the towers, it could cause big battery drain.
Keep an eye on what might be causing your battery drain though. It might be something silly like an app trying to do something.
I have also noticed a sharp drop in battery life now that I'm on 5.1.1.
USA AT&T.
I'm really at a loss. GSAM says "Android System" under apps as well as "Phone Radio" are the highest drain.
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine
