It's already updated, it does that automatically, I just think there goes something wrong with the initial update :).

EDIT: made a seperate thread for this fix for people to try it out.

http://xdaforums.com/galaxy-s7/how-to/standby-drain-2-8-hours-wifi-bit-4g-t3416864/

It really seems to solve the drain in standby, because it does doze. android system drain stays when phone is awake. But since most of the time the phone is on standby, people experience much bettery battery life.
[Samsung Galaxy S7 Guides, News, & Discussion] Theandroidfan:
Did you restart your phone after doing that or did you just re-enable them straight away?
[Samsung Galaxy S7 Guides, News, & Discussion] quarintus:
You can reenable them straight away. A restart after that is recommended I guess, probably gets the apps updated faster. But it's not really needed. Certainly not in between.
[Samsung Galaxy S7 Guides, News, & Discussion] DSF:
Lately I've found that the phone is preety warm when using, even lightly.. and i found a new process that eats cpu (and battery life). spi1.. do anyone of you have this issue?

I am so tired of android inconsistencies.. inconsistent memory management, inconsistent battery life.. core apps going crazy, etc.

Update: after a reboot, the spi1 process doesn't appear in the top list. It seems that this is related to gps/location, as soon as i use something that needs gps the process shows up. After i close the app the process goes away from the top. But i cannot understand what made the process hang there, since no location was triggered at that point, even with location disabled the spi1 process consumed cpu. So...

battery lasts all day at work for me watching movies and playing games etc
[Samsung Galaxy S7 Guides, News, & Discussion] superleeds27:
Long story short, I had an issue with my smartwatch 3 not syncing certain apps all of a sudden.

Backed up my apps with smart switch and did a factory reset. Cures the watch issue and battery life seems better than before. The thing is, my battery life before wasn't that bad either.

The issue with the touchacreen, far bottom right hand corner being temperamental seems to have been cured too!

Strange one but.... Yeah!

I am now on APG3 software and my phone is struggling to get 2 and half hours SOT on full charge ?
[Samsung Galaxy S7 Guides, News, & Discussion] Silvers91:
Ok I can't believe this too, but I'm getting some amazing battery life here! I've never imagined that this phone could last this longer, gonna reach 7 hours of SOT with more than 30 hours off the charger, I'm so freaking amazed and satisfied :svetius:

Usage: 20% on 4G and the rest on wifi, heavy usage including lots of youtube, netflix and browsing.. some gaming on clash royale, some calls.. gps turned off, nfc as well, I have sync turned on for gmail, brightness between 40% and 80% depends on the situation.

I'm on latest stock ROM, rooted and I don't use any app like greenify or powernap.
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
That's incredible I have no idea what's going on with my phone
[Samsung Galaxy S7 Guides, News, & Discussion] quarintus:
I updated the fix I suggested in another thread. I totally forgot about two other settings I changed.

Maybe that's why it only worked for some people until now.

Someone care to try it?

Please no reactions like: this doesn't work, it cannot work. Becasue it worked already for SOME people. Just try it and then report back if it worked for you or not, and if you are using exynos or snapdragon. If you are not experiencing drain, then it's no use to try this.

My battery has been ok I think so far. Can't complain. 14 hours since unplugged. 53 percent left. One hour and 45 minutes screen on time.

Always on display on. Auto brightness on. Google now cards on and all syncing of Google services. One thing I never have on though is location. I always turn it off in all forms unless I'm using maps to navigate. It's what drives Google play services and search apps to drain a lot of battery I find. Well it's one of the factors anyway.

If I were to use the phone more I can get 3 or 4 hours screen on time depending on usage. Can't complain at that.

Managed to get solid battery by:

1. Greenify Aggressive Doze

2. Using Game Tuner from Galaxy Apps to limit Snapchat's resource usage (one of the worst offenders ever in terms of battery use)

3. Turning off Always On Display

I've downgraded to March apc8 firmware. Will give it a few days to see if I get an improvement
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
Slight improvment on apc8 would still like to be getting over 4 hours SOT though with longer battery life overall. Currently on 26% with over 9 hours on the battery.

---------- Post added at 04:53 PM ---------- Previous post was at 04:52 PM ----------

Can you elaborate on that fix for snap chat? Seems my snap chat is using quite a bit of battery too it might help me as well
[Samsung Galaxy S7 Guides, News, & Discussion] AB__CD:
Go to Galaxy Apps, download Game Tuner, swipe in from the drawer on the side and from here you have two options: 1. Mark Snapchat as a non game app and be able to limit its resolution to a certain percent, or 2. Mark Snapchat as a game app and have finer control over the texture and refresh rate and all that.

Which rom
[Samsung Galaxy S7 Guides, News, & Discussion] theo5388:
stock

just changed some settings, turned off things I don't need, uninstalled and/or disabled bloatware.

Went into recovery, wiped cache. Did factory reset. Wiped cache again

Removed/disabled bloatware and other unnecessary apps. The ones that are disabled, I removed all access permissions, and also turned off notifications

Went back into recovery and wiped cache once more

AOD is off

Wifi stays on during sleep

Bluetooth is always on (as it's connected to my Gear S2)

Mobile networks changed to 3g/2g

NFC off

Nearby device scanning off

Smart Stay on

Keep screen turned off

Advanced features : all on

Location is on and on high accuracy (but turned off bluetooth and wifi scanning)

Everything to do with Google Now turned off

App power saving, all apps set to Always

Turned off Google and Samsung backups

Removed Facebook (using Folio instead)

Applied Android N theme

Judging by the mAh your screen used, I guess it was pretty dim most of the time, right?

Still insane SoT
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
I can happily confirm that disabling the built in Facebook app and using Facebook through chrome has significantly improved battery life.
[Samsung Galaxy S7 Guides, News, & Discussion] quarintus:
Yes a lot of people have found this. Thanks for sharing. Some people say it won't help, but it's important to fully switch it off. Depending on the firmware (country/provider) facebook comes baked in with multiple processes. Just disabling the main program sometime doesn't work. I had 3 processes running: facebook, facebook app instaler, facebook app manager. Just disabling facebook kept the other too still running....
[Samsung Galaxy S7 Guides, News, & Discussion] theo5388:
yup, I don't have it any brighter than what I need. I guess that's the great thing about a screen with such a high contrast ratio, can still see perfectly fine even at low brightness levels.

I've now installed the Superman ROM and Superkernel. Now I'm messing around with voltages and doze settings to see what kind of stamina can be squeezed from the S7
[Samsung Galaxy S7 Guides, News, & Discussion] deereper:
Awesome, make sure to share your results
[Samsung Galaxy S7 Guides, News, & Discussion] KevinB88:
Using Superman Rom, brightness around 75%, WiFi, some browsing and gaming. Still 10% battery.

Hello everyone, well I have to day that I'm disappointed with the phone, I mean battery life. I own it for 2 weeks, and I can say that until now if I get 3,5/4 hours is a lot. That is not what I expected, comparing to my OPO.

I'm really thinking about selling it, any solution at the moment? My usage is Facebook and 2 email accounts and the normal playing and 9gag, but nothing extreme, I would say 20 min of gaming max. Guys if you can pass me some feedback. Thanks

[Samsung Galaxy S7 Guides, News, & Discussion] gsmyth:
Which model do you have, exynos or snapdragon? Have you done all the standard stuff? Uninstalling/disabling anything you don't need, switching off things you aren't using (nfc/bluetooth/4g/uneeded account or app syncs). Im not a very active Facebook person but do check it to keep up to date with friends, I disabled the official built in app and use tinfoil for Facebook, it's on the play store and is more or less the browser version so it won't sync/update/use resources in the background. I also set the screen brightness manually and usually keep it around 30% brightness where possible.
[Samsung Galaxy S7 Guides, News, & Discussion] vlc_marcos:
Hi, I have the exynos model. Well I did disable all bootloader that there is with the application Samsung administrator. Well about the Facebook application, is like I said, I give the same usage in the OPO and Samsung with same applications, so I count that what is influencing is the phone it self abs not the applications. I'm really disapointed .
[Samsung Galaxy S7 Guides, News, & Discussion] gsmyth:
I also had the OPO and can agree it had great battery life, I think on the S7 the high resolution screen chews up more power, obviously the OPO had a 1080p screen, along with the snapdragon 801 it was very efficient. I also think kitkat was the most battery friendly Android version to date, they had to bring in doze to help things in Marshmallow and it hasn't been that great especially compared to how good it was back in the 4.4.4 days. As always battery life is going to vary from device to device and user to user. Many users say there is a significant increase on the S7 edge, although the comprises is the bigger screen (if you're not into big screens). Its really up to you if you can live with the change and hope an update improves things, or go down the custom rom root to take things a step further.
[Samsung Galaxy S7 Guides, News, & Discussion] beankid:
Has anyone gotten worse battery life since the new security update on AT&T? On a flat S7 with the extra apps disabled, I barely get 2hrs SOT. I leave bluetooth on and turn wifi off when I am not at home. The rest of the items I leave off and the device syncs as needed. I'm honestly shocked that in 2016 I can't get a device that I can just leave all this stuff on and not worry about it draining out the window when I don't have a clear shot of a tower. This is crazy, makes me think I've got a lemon and I should be looking for a new device already. I really do enjoy the phone and would keep it if I didn't get such bad battery life. I can't go a day without having to plug the device in before I get home. This is the same situation I had on my old G2 when the battery was dying and had to be replaced.

[Samsung Galaxy S7 Guides, News, & Discussion] makhoder:
Hello, i noticed that after the last update Samsung Push Service is draining battery, it is the second charge is happening after the update.

I still did not restart the phone after the update, gonna try now.
[Samsung Galaxy S7 Guides, News, & Discussion] id.goPLAY:
Try this:

Go to Settings > Privacy and safety > Location > Improve accuracy and turn OFF WiFi Scanning und Bluetooth Scanning Options.

(The WiFi Scanning Option will be enabled every time after Firmware update.)

Second think, go to Settings > Lock screen and security > Other security settings > Device administrator and set it OFF.

Use NFC, Additional device scanning, Location and Nearby scanning device when you need it.

I hope it will help.
[Samsung Galaxy S7 Guides, News, & Discussion] Ionut Ciprian:
This was the best SOT ever for my S7.

No root, greenify, package disabler or anything else.

My CSC is BTU, and this result was obtained before the update installed this morning.

Mostly used while connected on wi-fi.

Do you have any issues with spi1 process taking battery life?

The device gets uncomfortable warm even with light usagw (no gaming, simple sites browsing).

Sometime the issue is fixed with a reboot, but the spi1 process start to be on top of usages again and again.

Any idea?

spi1 consumes more with gpsd (when location is queried)

Hi guys,

I'm really happy with my S7 which is better than my G3 for battery life but when i compare with you guys, my battery is awful

I got 3h (sometimes 2h30) SOT before "battery low", i just use my phone for snapchat, messenger and sms, auto brightness on, location enabled when i need it, 4G enabled, BT off, wifi off (don't have it)

I had 5h SOT one time but i don't know how i did it. I have gsam battery monitor, i check my battery usage, nothing wrong

screen first, snapchat and facebook after, etc
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
You have a 3000mAh battery, have a look what is using the most mAh in the apps and work it out from there
[Samsung Galaxy S7 Guides, News, & Discussion] MisterIchiban:
Snapchat and Messenger, after the screen

But i "need" snapchat and messenger so ... i can't delete them
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
Then you'll have to accept poor SoT

Some apps drain the battery more than others, nothing you can do about it other than report them to the dev and hope for an update fix
[Samsung Galaxy S7 Guides, News, & Discussion] MisterIchiban:
Well ... Snapchat and Messenger improving battery usage ? let me laugh hahaha

Everybody is asking for this since a looooong time

I reduced fps in Snapchat, i will do it for Messenger and see if there is any improvements
[Samsung Galaxy S7 Guides, News, & Discussion] *Detection*:
I've got an app that lets me view my CCTV, that app could drain a full S7 battery in about 30 mins

Set snapchat to always power save in smart manager battery settings if you don't need it to run in the background, messenger will need to for notifications though

Most satisfied with my G930F battery life

G930F (Exynos 8890)

- official firmware

- rooted (CF autoroot)

- debloated

- Android security patch level - Aug 1, 2016

- lots of "App power saving" ticking

- no Facebook or PokemonGO at all

- frozen (via Link2SD):

. ANT related services

. KNOX related services

. All Samsung apps (store, billing, etc)

I don't know why my Antutu score is about as low as 117k, but I'm fine with that and quite satisfied with overall battery behaviour.

Cheers

Is SOT a good juice consumption metric?

I make lots of voice calls during a working day, using both carrier service and Whatsapp voice, only RIL sucking down the juice, as I wear earbuds and keep my G930F facing down my desk (screen off). As I see it, SOT doesn't directly equate to reliable batt drain measuring. All in all, global amps consumption is the metric I trust most; others' mileage may vary.

[Samsung Galaxy S7 Guides, News, & Discussion] jioleight:
so yesterday (09/22/16) I was charging it with stock charger and fast charging on. and unplugged it after 100%. I played with it for about 30 mins while charging (usually just browsing). I woke up around 6am to check what time it was on my phone and went back to sleep. around 10am I was woken up because my s7 got hot. (was holding it while asleep). so i just checked what was going on. but when I pressed the power then home button the screen didn't turn on, tried the power + vol+ +home or power + vol- +home and it didnt work. the device was really heating up. maybe around 40-50C, sorry dont have a thermometer cant give an exact measure. fearing that it might explode if it heats up more. I hurriedly went to samsung service center. when I got there the temperature was slowly decreasing. but still the phone wont turn on. by the time i handed the phone it was no longer hot. the juice might have run out already by that time. I turned it in around 1pm. and got it the today (next day 09/23/16) around 4pm.

they said that the board got short circuit. i dont know how or why it got short circuit. :/ I charged it twice on tronsmart with qc v2 charger few weeks back but that was it. charged it once with a silvertee @2.1A charger too.

[MENTION=4228669]RGold55[/MENTION] didnt mean to quote you
[Samsung Galaxy S7 Guides, News, & Discussion] RGold55:
My experience using Samsung original charger shows me that

- fast charge set: heat, 1h10min remaining, from 17%-100%

- no fast charge set: no heat at all, 1h24min remaining, from 17%-100%

Being so, the extra heating gives me no big advantage besides the 14min shorter charging time. On the other hand, the shortening of batt life time should be considered.

Cheers

I followed the debloat your s7 device in the how to section and I've been happy so far. One graph pic is from ~9pm before going to sleep the other is at 7am when I woke up.

I forgot to mention it's a 930F non-rooted. The only mod is disabler package pro and a CSC file for SPay. Also anyone know why my mobile carrier doesn't show up in the top left? It only shows on the lockscreen (of course this is when airplane mode is off).
[Samsung Galaxy S7 Guides, News, & Discussion] beankid:
For those of you who are getting 24hrs on a charge, what's your normal usage like? Are you being delicate with your phone and not using it, only using wired headphones at a certain volume or are you using it normally, ie gaming, syncing email, enjoying the phone taking pictures not worrying or careing about battery life and that is what you end up with?
[Samsung Galaxy S7 Guides, News, & Discussion] crazyjurich:
May be my experience helps someone. Recently noticed that my battery life dramaticly decreased. I charge overnight and it usually had 30-40 percents left when I plugged it in. But now it even didn't last till I want to plug it in, it cries for power few hours before. And battery usage shows Android System on top. Always. It used about 5-7% in an hour, even if not used.

BTW I'm stock.

I tried all sorts of monitor, analyzer, disabler apps. Nothing helped. Then I went to inspect system settings and came to Samsung Cloud page. It said it was unable to sync. It looked suspicious and I removed samsung account (it's useless junk anyway). And the problem was gone!

And now I'm home in the evening with 60% left, victory!
