Just an update.

In the last 10 months i had no problem at all at night on flight mode after installing the november 2018 patch from Samsung with a new modem. So seems it was a modem software problem.

Now battery drain is 1-2% every night (8-9 hours in flight mode). Like when the phone was new.

Anyway now the battery life is good again.

Sorry i still can't post pictures due lack of comments . At 20% i plugged to charge it was 6:20 sot. All the time it was one wi-fi , it's my second day then i have it so i was downloading couple of apps that i forgot to download yesterday. I was chatting on messenger allmost all the time also played for 45min( not for straight for about 10-15min one time , then another ) asphault 8 . Also i left always on display on. And brightness was set on auto. Tommorow i'm going for whole day trip so then i could tell more .

It's an uninstalled app
[Samsung Galaxy S7 Guides, News, & Discussion] conquereddroiduser:
My first full day of use yesterday with the S7 (SD820) and I'm pleased with the results: 4:30SOT, 18 hours off charger. Mix of Wifi/LTE. Had bursts of heavy use when I was playing with the camera, installing apps, and running speed tests, but mostly was web browsing & social media. I left on auto brightness the whole time, location was off mostly.

My one concern was that the phone wasn't dozing so I unplugged it halfway through the night and thankfully it dozed just fine according to gsam, losing 2% over 6 hours. I guess I just didn't leave it sitting long enough to doze during the day.

Awesome better than my sd820 gs7

Getting amazing battery. Sprint version.
[Samsung Galaxy S7 Guides, News, & Discussion] PlatinumNick:
I would like to also remind people that this is a regular s7 battery thread not s7 edge we dont want no confusions, These numbers are looking so great, and also if you can possible put which version phone you have also exynos or snapdragon, thanks all
[Samsung Galaxy S7 Guides, News, & Discussion] insang-droid:
There is definitely some off screen, background battery drain that's not as good as a Nexus phone. If Sammy can resolve this with a patch, I think this phone will last 2 days. Again reminds me of the LG g2 when it first came out
[Samsung Galaxy S7 Guides, News, & Discussion] WebsGhost:
Hi guys,

I got the Exynos version and the regular SGS 7, wanted to know, how much the battery supposed to hold? i dont play games. most of the time using: LTE\WIFI mixed, gmail and Inbox. some weather widget (beautiful widgets), exchange email, some youtubing,internet surfing, facebook, Whatsapp.using the "Auto brightness"

I have to admit that i feel, it's "dying" to fast for a 3000Mha battery

thanks alot for your help

[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
Unless you post screen-on time, it doesn;t make much sense.

Disable AOD if you want good standby.

Check your display brightness.

Allow 4/5 days for usage to settle before you judge anything

Stock Facebook app is probably the biggest battery drain in entire universe, use some third party clients.

Probably disable some bloatware if you could/want

Use GPS only when required

Use black theme with AMOLED

Bad network will affect your batterylife pretty bad.

Typical points which are applicable for any phone

I have the Phone for about one week, and for now I am pretty impressed. Easy one Day, even with alot usage.
[Samsung Galaxy S7 Guides, News, & Discussion] cc999:
Not good

My nephew works for Verizon, he has the S7 as well as he is selling them.

According to him the battery life stinks. He cannot get through the day without

charging and thats with minimal use. Seems to be complaints of people who

are purchasing the phone also.

The Edge version is the only version with acceptable battery life.

[Samsung Galaxy S7 Guides, News, & Discussion] PlatinumNick:
out of that whole article the only thing you got out of it was its not a big improvement lol, if you look at the overal score between the two phones its a huge improvement.

Your getting A whole day of battery life off your phone theres nothing wrong with it, just be patient
[Samsung Galaxy S7 Guides, News, & Discussion] dzemik:
So after my trip i got this :

Allmost whole day on LTE (4g) mostly chatting on messenger , looking threw facebook , played a bit of asphault 8 and listening spotify ( not for very long about 30min) i got 13h32min on battery 3h10min sot , auto brightness and still left 33% .
[Samsung Galaxy S7 Guides, News, & Discussion] Kenshin11212:
I've been getting about 4 hours SOT. I just uninstalled the Facebook app and will test just browsing through the web browser rather than the app itself. Let's see if that helps me achieve these amazing battery stats I keep seeing on here. I've been getting better battery life on this phone than I have on most of my previous phones, but it's still disappointing when it's dying faster than I expected, especially when people are posting how they're getting over 50% more battery life than me. =/
[Samsung Galaxy S7 Guides, News, & Discussion] WebsGhost:
Thanks for your help,

what's AOD stands for?

Probably disable some bloatware if you could/want - did that

Use black theme with AMOLED using a black one

here is the screen on time
[Samsung Galaxy S7 Guides, News, & Discussion] PunishedSnake:
Been looking at gs6 with 6.0 and it seems to have massively improved it to near gs7 levels. Seen 6 hr sot with no android os or system drain. On at 2500mah battery

I've hit 7.5to 8 hr sot on my gs7 imagine what we could get without that 1000mah android os usage after 20 hr
[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
6hr 42min screen-on time is very good. If this is in a day's of activity, I don't think you can find a phone with better batterylife.

AOD - Always ON Display.
[Samsung Galaxy S7 Guides, News, & Discussion] WebsGhost:
i've disabled it..

ok then, thanks alot for your help dude :)
[Samsung Galaxy S7 Guides, News, & Discussion] kind3r:
SM-G930F (European Exynos version)

25h42m with 6h29 SOT (mostly playing some games over the weekend) still at 14% left.

- Google Now disabled

- All other sync enabled

- Mostly on WiFi

- Connected to Gear S2 Classic

- AOD off

This is not my typical usage so I'm assuming 2 days with 3h SOT is most definitely not a problem.
[Samsung Galaxy S7 Guides, News, & Discussion] PlatinumNick:
its very hard to compare battery life on phones because theres a million factors, like apps installed on phone and the main factor is where you life and cellphone reception, you have to take those into consideration
[Samsung Galaxy S7 Guides, News, & Discussion] Kenshin11212:
Fully charged my phone last night, uninstalled the FB app, and used the phone a bit before going to bed. Phone dropped to 88% by the time I went to bed. Just woke up 6 hours later to my battery being at 74%. 33 minutes SOT. Chrome, Android System, Android OS, and Cell Standby are all showing higher battery usage than the Screen. What the hell, guys?

PlatinumNick, I downloaded 2 or three apps that I use to clock into work and check work emails. Besides that, my phone has pretty much just has stock apps. I disabled the useless ones. The ones I once in a while use, I disable anything in the app settings that would have it running in the background and draining battery. And just in case there's anything I miss, I set the permissions accordingly so they definitely don't do anything in the background that I don't manually have them do. So basically the only app I was using on a regular basis was Facebook and FB Messenger and those were the only apps showing in the battery usage. I disabled them last night and have just been using chrome for that. I have a 4G LTE Cell Spot in my house so I always have full bars except for the 5-10 minutes I'm underground in the subway going to and from work. And now I'm sitting at 68% with 40 minutes SOT. Seems like it's only gotten worse since I disabled the only two apps I use. lol

It's just disappointing because I use this phone for work. I do have an LG V10 as my personal phone that I use for calling and texting and yada yada. But prior to upgrading my work phone to S7, I was using an iPhone 6s. I've always been and Android guy since day one, but I was just so blown away by how good the battery life was on the 6s. I started using it for basically everything short of making phone calls because i knew I could do everything on it and not have to worry about charging my phone until the next day. I was using FB, texting, doing work stuff, streaming video and music, and playing graphic intense games on it no problem and wouldn't have to charge the phone til the following night.
[Samsung Galaxy S7 Guides, News, & Discussion] Alpione:
Good comparison, with the Always On screen being most interesting part. Samsung and GSM Arena both say that it takes about 1% per hour, but keeping it on drops their overall battery life rating from 80 hours to 49, almost 50%. That seems to suggest a lot more than just 1%/hour.

I like it, but since it doesn't work well with notifications from non-Samsung apps I don't feel like I'm missing much turning it off. I wear a watch anyway. Just turned it off and will see how it compares for my use.

[Samsung Galaxy S7 Guides, News, & Discussion] NisseGurra:
1% /hour, 40 hours = 40%... So the Gsmarena seems correct.
[Samsung Galaxy S7 Guides, News, & Discussion] Alpione:
Ok - you're right I was looking at the methodology incorrectly. Thanks.
[Samsung Galaxy S7 Guides, News, & Discussion] NisseGurra:
S7 Exynos rooted and debloated.

Very happy with the battery on the S7, even better than the mighty Lg G2
[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
4hr SOT, and 64% left! Amazing :good:

I think that i've got a problem, what do you think please ? :cowboy:

I can't post screen because i'm new, actually in normal S7 :

- 28%

- 13h 11m 32s on battery

- Screen on since 2h 8m

Ty man
[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
Snapdragon or Exynos?

Find out what's the worst culprit. Mnitor how much you lose during sleep, would tell you something about standby drain.

Your network strength could play a big role in batterylife, bad network sucks battery.

Do a factory reset, remove apps which are not must and disable bloat. If nothing else works, maybe a bad piece.

---------- Post added at 01:19 AM ---------- Previous post was at 01:12 AM ----------

Posted it on Edge forum as well. Exynos have better batterylife.
[Samsung Galaxy S7 Guides, News, & Discussion] Burns2k13:
Thank you for your reply.

I turned off every bloatware that i don't use. Have no less than medium network..

I come from iOS with the cable directly on S7, could that be the problem ? :confused:

[Samsung Galaxy S7 Guides, News, & Discussion] garyd9:
Has anyone loaded something like 'cpu spy' to determine if the device is going into deep sleep and how often?

Some of the numbers that people are posting almost sound as if the device isn't actually sleeping (even if the screen is off.)

I've NEVER seen a new device released that doesn't cause a massive "battery life" thread here on XDA. Don't panic, don't over-react, and things will settle in.

Things to consider (that I haven't seen yet in this thread):

Every new device (or newly reset device) usually has a period of a few days while location services eats entirely too much battery. My opinion (no proof) on this is that Google's location services (even if turned off) will cache data for those first few days. (Without root, it'd be difficult to isolate the specific cause of why the device is chewing through battery.)

Carrier specific devices might have carrier specific crud on them chewing battery. (Yes, even TMO.) That might better explain the huge differences between the SD820 and Exynos. Are there any non-carrier SD820 devices out there?

Sometimes, disabling packages can actually cause more harm than good. If package "A" depends on package "B" existing, and you disable package "B", package "A" might keep the device awake while trying to talk to package "B". I've found that these inter-dependencies are especially prevalent with TouchWiz devices. Finding them can usually only be accomplished with trial and error. (Often, these packages won't give enough, or any, log information that's useful.)

[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
It takes few days for battery life to settle down (say 4-5 days). You'll need to find what's causing the drain.

Perform a factory reset and disable bloat. Don't install many apps immedietaly, just have a few which are must for you.

Turn off location when not required. Turn off Always On Display option

Check your battery consumption while you sleep, shouldn't be more than 4-5% for a normal phone.

You can use this app to check consumption: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en

Snapdragon 820

On my first charge to 100% out of box and subsequent discharge to 6% I got over 5hrs SOT and the device lasted over 2 days lol

Not sure what's going on with these other Snapdragon 820 devices but you should definitely be getting that battery life. First night while I was sleeping in a 6hr period I lost 0%. That was a definite first for a non-rooted Samsung device for me.

Maybe you have some rogue apps installed.

On a S7 or S7 edge...

Edge models are getting that all the time. I haven't seen a S7 get anywhere near that. I have an AT&T model. Get 3 hrs max screen time to 15% over 11 hours. Most of the time it's like 2 1/2 SOT over 11 hours and the phone needs a charger...battery life is no better than a S6.
[Samsung Galaxy S7 Guides, News, & Discussion] s3icc0:
I hope my battery is not settle yet (at least i hope), but with all S features ON I am able to stay like for 24hours with approx 3,5hrs screen on time. (wifi on, gps on, step counter in shealth on, aod on - like I said everything on).

Cannot say it is dissapointing resoult - I was kinda expecting the phone to stay live from 6am-10pm every day - that is what I need.

Anyway if you fast charge your phone and take it off the charger when on 100% then the first 20% disappears very quickly - I recommend to really leave it on charger at least 1:20-1:30hrs.

mine is exynos model - standard s7

Well my s7 exynos is getting bad tI message. I'm on 8:45 battery and 3:45 sot . As well as my phone is fairly warm to the touch when browsing it's 30 to 34 degrees and playing a graphic intense game it sits at 38 to 41 degrees. Not sure if the heat means more battery drain. As some people say their s7's doesn't get warm at all.

Does your s7 get warm everytime you use it? Or are you using a cover and you don't notice?

really starting to think its the AOD thats causing the drain. I turned off the AOD this morning and I can finally see the doze feature doing its thing!

SM-G930F (Exynos)

40h38 total with 3h26 SOT left me with 19% before going to bed so I'm assuming 2d with 4h SOT is doable for me.

My regular usage (Facebook, Hangouts, Chrome, Maps, Uber).

Location always on with history and location sharing enabled.

AOD off.

NFC on (forgot to turn it off).

Sync on (gmail + exchange).

I would say it's 30-40% longer lasting than my S6 Edge.
[Samsung Galaxy S7 Guides, News, & Discussion] skiddingus:
It appears that the S7 has the same problem that my S6 had. The bluetooth just being enabled kills the battery. I have a seperate work phone so my personal S7 spends all day collecting dust on my desk while I am working. I noticed the battery seemed to be dropping rapidly even when I am not using the phone. I did an experiment today. I was at 100% battery and I did not touch my phone for 4 hours with the bluetooth enabled. The battery fell 13%. I then disabled bluetooth and didn't touch the phone for 4 more hours. This time the battery only fell 3%! My S6's bluetooth did the same thing. The S6 did not have this issue when it was new but started eating battery after an update about 6 months ago. My wife's S6 has the same issue. Is anyone else seeing your battery drop quickly with bluetooth enabled?

SM-G930FD (Exynos)

I managed to get 41h48m with 2h11m SOT with 52% battery remaining. Very moderate usage: Facebook, Gmail, some Camera snaps, Instagram, some file transfers via WiFi (SendAnywhere) and Twitter (no music and game activities yet). WiFi, NFC and Location were always on, mobile data is off (didn't tried it yet), Bluetooth off, disabled AOD, Sync is on and no power saving mode. Pretty satisfied so far with the efficiency of Exynos in terms of battery usage.

Couldn't attach image link since I'm new here and still need 8 post to do so. :p hahaha

I have the att variant... Slept for 10 hours last night and my deep sleep for the whole day including last night was only 5 hours, so there's obviously something keeping my device from going into deep sleep quite often.
[Samsung Galaxy S7 Guides, News, & Discussion] mrvirginia:
yes, this is correct. on my second night on the same first discharge of the phone, i accidentally left BT on and it sucked 8% of the battery over a 6hr period compared to the previous night when i had it disabled and the battery lost 0%. that was the only difference between the two nights.

so, when i'm not streaming music in my car, i turn it off. there is a low power BT setting that i saw that you could turn on and still keep BT off. i haven't tried it but that could be an alternative. settings -> more connection settings -> nearby device scanning
