As more leaks and rumors flow forth on upcoming "Always on" screen of Galaxy S7, it's easy to become prematurely concerned about what it all might mean for the battery life. Let's wait and see.
[Samsung Galaxy S7 Guides, News, & Discussion] PlatinumNick:
I dont believe the report about the battery being 2800mah in this article which was written today says its confirmed 3000mah

How does that link in the OP prove anything about the size of the battery?
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
This is the only info I could find. You are welcome to add in any new information you have.

GSMArena is one of the most trusted sources out there!

http://www.gsmarena.com/samsung_gal...re_reveals_all_march_11_launch-news-16735.php

It's settled, 3,000mah for the S7 and 3,600mah for the S7 edge.
[Samsung Galaxy S7 Guides, News, & Discussion] thekoRngear:
next thing I wanna know will the batteries be removable?
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
Don't think so, look at the leaked video and pictures. The design is very similar to Galaxy S6.
[Samsung Galaxy S7 Guides, News, & Discussion] kingoanklebreakn:
Nope!
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
Now LG has upped their game with G5 on removable / expandable battery. Fingers crossed for how Sammy plays it.
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
So it's official that 3000 mAh for GS7 and 3600 mAh for S7 edge.
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
The screen features an Always-On function, which will draw 1% battery charge per hour.
[Samsung Galaxy S7 Guides, News, & Discussion] TikiThePug:
I've read that it's actually 0.5% per hour (thanks to AMOLED), and it will actually turn off if proximity sensor is covered (i.e. if it's in a bag or pocket).

How can I improve battery life without root? I'm on the Snapdragon 820 version so root is unlikely :/
[Samsung Galaxy S7 Guides, News, & Discussion] Doublear:
Today I got my S7, after unpacked I put it in charge. Start with 45%, after 3 hours still 45%. I tried with a factory reset, it shows 98% and 5 minutes after 66%. I tried with other charger and cables but it stays always on 66%.

Any suggestion? It's defective?

Thanks

Some times Google services just goes nuts. I lost about 10% overnight, 55% use Google services. This happends an all phones and it's random.

Here is my first charge:

S7 exynos , 4g, high accuracy location, no nfc no Bluetooth mostly Wi-Fi use brightness auto no apps disabled.

[Samsung Galaxy S7 Guides, News, & Discussion] sychen79:
Sorry no tricks.. Turned off always on display.. Rooted as well.

Did do a factory reset.. As I screwed up messing up my titanium backup restore at my first go.. Forgetting Samsung's don't like all of asop crap. Second go I let play store download all the apps first and restored data only.

This was usage that day.. Didn't get more details. Sorry. Close to 2hrs of clash, some gps, calls, Web, tapatalk.. And plenty of kindle reading.. The usual.

I don't always get get 7 hrs daily... Between 5 to 7..lots of Spotify drops it to 5hrs sot.

I was getting about 4-4.5 hours screen on time. Always on Display is off, and brightness is set to auto.

I think i hit 5 hours yesterday because I used WiFi in the morning. I guess the S7 battery life takes a much bigger hit from using the cellular network than other phones? But I'm experimenting with it. I'm off today so I'm just going to be home all day only using WiFi to see how big of a difference it makes. So far I'm at 3h 6m screen on time with 51% battery left.
[Samsung Galaxy S7 Guides, News, & Discussion] thafz:
Use gsam app from playstore
[Samsung Galaxy S7 Guides, News, & Discussion] Kenshin11212:
Yeah seems like going off the cellular service really does a number to the battery on the S7. Been connected to WiFi all day since it's my day off and I had a lazy day. Screen on Time is on point. Getting two hours more than I usually was getting.
[Samsung Galaxy S7 Guides, News, & Discussion] redeye25:
My first S7 had amazing battery life. Didn't get a screenshot as I had to send it back the same week for random reboots, but it lasted me almost 2 full days with my general use.

My replacement S7 sadly is only achieving about 4 hrs SOT like some others reporting here.

Same exact apps installed and very similar usage, or rather less as I've been working and it's just sat there on my table for the main part of the day.

The battery on this one dropped from 100% to 97% in literally a min of googling. And it seems to lose 1% every 20 or so mins when sitting idle which is rather fast for AOD off.

Am in the process of trying to fully let the battery run out and then charging to 100 without fast charge and seeing if that's gonna help at all.
[Samsung Galaxy S7 Guides, News, & Discussion] sychen79:
Another 7hr SOT day.. 3hrs of clash but on number 4 in usage.
[Samsung Galaxy S7 Guides, News, & Discussion] Kemby13:
Nice sot you got there. I get a bit less sot but i do play a more demanding game... Wifi on all the time, 4g for only couple of hours, auto brightness on...

Here are some screenshots from yesterday:
[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
Yea i still barely get 4hrs SOT with AOD off and greenify. Screen off drain is insane, not sure why
[Samsung Galaxy S7 Guides, News, & Discussion] KoRoZIV:
No AOD, I just don't like it. That's the only thing I stopped, and that briefing page from the launcher. Mostly Wi-Fi use, browsing, tapatalk, some music over Bluetooth, tried about 6 music apps (install/uninstall) some YouTube videos.

The YouTube app is not in the list, no ideea why.

Edit : exynos s7
[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
That's pure bonkers. How much is the screen brightness?
[Samsung Galaxy S7 Guides, News, & Discussion] KoRoZIV:
Auto until 15% battery. After that I un ticked auto and and lowered a little as it was dark then.

4 am here so still dark here. There is very little difference from auto to my value.

Edit

I used location on high accuracy, probably disabled it when swiping the screen for screenshot.
[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
Does the exynos variant just have much better battery? I've never gotten more than 4 hours SOT with my Verizon S7 and I don't even game. Usage is mostly text, social media, emails, some YouTube
[Samsung Galaxy S7 Guides, News, & Discussion] KoRoZIV:
I'm inclined to believe that the GSM signal has a big role in battery usage. I had excelent / decent 4g coverage until now. But the battery is great, I was getting around 4h sot with an lg g4, and that on 3g (no b38 band on g4)
[Samsung Galaxy S7 Guides, News, & Discussion] xMinistro:
S7 Exynos here. I got 5-6hours standard SoT. Games, social media, youtube, etc. The power saving is almost always on though. Try to disable more of the advance features/smart features there as it uses your sensors even when you're not holding your phone. It also avoids your phone to doze.
[Samsung Galaxy S7 Guides, News, & Discussion] redeye25:
Exynos here. As per previous post, I only get about 4hrs SOT. No games, AOD or other fancy features turned on. Do have WIFI (or 4G), Location and Bluetooth on 24/7 for my watch, emails etc

Not a social media person either but am constantly sending / receiving emails for work so I suppose 4hr SOT isn't so bad, but some of the figures you guys are getting are crazy :o
[Samsung Galaxy S7 Guides, News, & Discussion] Rlin5741:
Knock on wood, but my initial testing for me (on Verizon, snapdragon processor) shows much better battery life after the latest firmware update (2nd since launch, this one's says there are wifi optimizations and security patches) that was released today.

1.4% per hour on idle, as measured by gsam. According to gsam, this was before doze kicked in...

AOD is off, pretty much everything else (OK Google, location, wifi, Bluetooth, etc, is on)
[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
Is that Verizon OTA the March security update?

Edit: Just checked and got the update, looks like it includes the March security update. I'm hoping this update improves battery... would love to get 5-6 hrs SOT.

My standby drain is pretty decent. I usually leave it unplugged overnight and lose about 4-5% which is ok but not great.
[Samsung Galaxy S7 Guides, News, & Discussion] Rlin5741:
It does have the update. My usage is naturally less during the weekend, but standby time is vastly improved. If they fixed wifi, this makes sense since I had noticed wifi jumping on and off the access point. Oddly enough the battery drain is higher (compared to before the patch) when the screen is on, 10% to 20% per hour rate.

Before and after is attached in order. You can see is the "before" pic that you can barely distinguish between sceen time and standby.
[Samsung Galaxy S7 Guides, News, & Discussion] chungdae:
Mine after a very heavy use of clash of clans and chrome. Deleted chrome and going to try the native Internet browser. Also at 75% to max screen brightness
[Samsung Galaxy S7 Guides, News, & Discussion] PaulB007:
I've been getting a lot of mixed reviews reading the threads about the S7 and the S7 Edge when it comes to its battery life and memory management, apparantly the Exynos is better (typical that we get the shaft here AGAIN) than the S820 chip.

I currently have the S6 and I remember that everyone and their brother was promising that it would be the next best thing since Christ walked the earth in terms of battery, speed, ect and I was sad I gave up my M8 for it. I have owned every Galaxy flagship except for the S1 and the S7 and I have to ask, why can't Samsung get it right across all of their phones instead of only some getting good life and some getting horrible battery life? The last time I ever got five or six hours of screen on time on ANY PHONE was with the Galaxy S2, to me it almost feels like we have taken many steps backwards instead of forward with battery life. How the hell can a 6 year old phone out perform a new one in terms of battery? I get it, the screens are better, processors more intense, ect, but still. I just wish we could get some consistency, I feel like it is a total crap shoot as to whether or not I am going to buy a phone with good battery life and that just shouldn't be the case with how advanced the tech is now.
[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
I feel like the S7 would be able to easily hit 5-6 hrs SOT if we had root and custom ROMs and kernels. Without root, I get 4 hrs SOT pretty consistently which is just meh
[Samsung Galaxy S7 Guides, News, & Discussion] Rlin5741:
I think in this case, the Exynos SoC didnt support CDMA, which is impt in thr US market. Also, Samsung probably needs to "man up," so to speak, and start flexing it's muscles with the carriers. Different versions for different regions can be driven by carrier contracts and carrier desire to block their customers from easily taking their phone and switching. Each carrier want their custom software and lock the phones from accessing other carrier LTE bands. In this respect, Apple has it right, force carriers to accept your phone as-is, the same version sold around the world.

Of course, once people can easily switch, carriers will stop subsidizing phones, either through the traditional method of service contracts or the current iteration of 0% interest payment plans. Which means people will start needing to pay full price or finance with real interest rates...so there is a cost to the consumer.

Of course, not flex so much they decide to ditch Google Android altogether :)

[Samsung Galaxy S7 Guides, News, & Discussion] Rlin5741:
First full day post the Verizon firmware update with the wifi fix. On SD820, previously got about 2.5 hrs SOT with 18 off battery, minimal voice calls. Today am at about 2.5hrs SOT, 2hrs voice, 16 unplugged. Note that voice took 14% while screen only took 11%.

I do continue to notice that idle drain is far better than before, but drain while in use appears to be a bit worse (about 1% for 4-5 min active use)
[Samsung Galaxy S7 Guides, News, & Discussion] ZeroCGTI:
Here's mine: http://i.imgur.com/VSaXh07.png

Summary:

55 hours total

Total time on screen: 7 hours & 40 minutes

Playing games: 3 hours & 30 minutes (AB: 2h 10m & AB: Space 1h 20m)

Wi-Fi: Always On

Mobile Data: Always On

Always-on-Display is off, I never used "Power Saver" but have "Limit background mobile data" and "App Optimizations" manually set to target all apps except for messengers (Facebook, What'sApp, Viber, Skype)

Pretty good, I think.
[Samsung Galaxy S7 Guides, News, & Discussion] jagman96:
I get pretty mediocre battery life compared to some of you guys. 4-5 SOT per day. SD820 on T-mobile. There seemed to be limited time in Doze and excessive screen off battery loss. I installed Greenify late last night. I Greenified a few apps and got lots of FCs so I deGreenified them. Once they were deGreenified the only thing I had the app do was use aggressive Doze. Look at the difference! Screen off battery drain levelled off nicely when I went to bed last night...
[Samsung Galaxy S7 Guides, News, & Discussion] jagman96:
Here's today as a follow up to the last post. Much better idle battery drain...

[Samsung Galaxy S7 Guides, News, & Discussion] lunzi88:
I'm constantly amazed by the battery life on this thing.

Pretty light usage i guess, since mostly reading and spotify for most of the day. but still 10hours of SOT is nothing to sniff at.

Dang, exynos version gets such better battery life than SD820 version. What tweaks have you done?
[Samsung Galaxy S7 Guides, News, & Discussion] sprog123:
SD820 version has a software bug where AndroidSystem easily consumes more mAh than even screen on does. It appears most people's screen on drain is very roughly around 100-150mAh/hour. On SD820 versions where AndroidSystem is draining say 800mAh and using up 40% compared to Exynos AndroidSystem only burning 10% and using up 200mAh, the SD820 version could have gotten another 600mAh, or roughly 5 hours more screen on time if the software bug wasn't present. That's equivalent of nearly 10 hrs SOT when you consider most SD820 versions are getting about 5 hrs SOT at 500mAh with an 800mAh Android System drain. I really hope Samsung fixes the software bug in Android System! Android System has so many components though (many of which are put on there by Samsung), it's hard to know which one is the culprit.
[Samsung Galaxy S7 Guides, News, & Discussion] km8j:
Gotta post to social media or this wont be fixed
[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
I just tweeted the issue to Samsung's US support twitter page, everyone else should do the same to get their attention
[Samsung Galaxy S7 Guides, News, & Discussion] beezar:
Good observation; seems like on the SD820 versions, the Android System consumes more energy than the screen and vice versa on the Exynos version when you look at stats posted on this thread.

Could be a bug, but I think it has to do more with the inefficiencies of the SD820 vs. the Exynos processor which would be a hardware rather than software issue. But you never know....
[Samsung Galaxy S7 Guides, News, & Discussion] dachao:
I think that it is a software issue. My GS7 is having other software related issues. Push notifications are delayed by 10-15 minutes on some occasions, sometimes apps freeze and over wifi or LTE it take a few seconds for data to star loading. I had similar issues with previous Xperia and most of it got fixed with an software update.
[Samsung Galaxy S7 Guides, News, & Discussion] insomnia:
i think its the subpar Qualcomm SD820 chip at fault. Company got too greedy after the rise to fame and has been doing a ****ty job since then.
[Samsung Galaxy S7 Guides, News, & Discussion] Kenshin11212:

[Samsung Galaxy S7 Guides, News, & Discussion] gleggie:
Awesome, I guess just let them know that it's a universal issue and that it's making idle drain really bad lol
[Samsung Galaxy S7 Guides, News, & Discussion] KoRoZIV:
Next thing: Samsung releases an update that cuts battery life in half for exynos, to satisfy sd820 clients and stop the complaints.

PS. All sarcasm in there; just in case someone missed it :)

I really hope all issues get fixed soon.

[Samsung Galaxy S7 Guides, News, & Discussion] rogerchew:
it's so hilariously glaring...exynos users post battery usage and screen is #1 by far, at 30+% with upwards of 7 hours SOT. SDS820 user posts and #1 is always Android System and most SOT of only 4hrs. There's 2 phones out there and one is clearly better by far. Sucks to be in the US.

Exynos SoC on Duos Variant (SM-G930FD)

My battery is pretty consistent and I'm satisfied so far, I got 5h 2m SOT with 39% remaining and I could easily pull 6 hours plus several minutes of SOT with 20% remaining with my current usage pattern: 4 hours of mixed usage of Facebook, Twitter, Instagram, 9Gag, Gmail and 12 camera shots (no video recording). The remaining 1 hour is from music listening using Bluetooth headset with APTX (local flacs/mp3 + Spotify over WiFi). Settings: WiFi is always on, Mobile Data is off, Location is always on, NFC is off, Bluetooth is only on during music listening, Power Saving is off and AoD is off. Screen brightness is around 25-40% depending on the lighting. :o
