Make sure you wipe the cache/dalvik cache after upgrading to Nougat. I did that and it solved the battery drain I was having post upgrade. I have been getting about the same if not marginally better battery performance from Nougat (and I was extremely cautious after hearing about problems), getting about 5.5 hrs SOT. Also using a G930F on UK Vodafone

I'm also facing huge battery drain problems...

I have a flat exynos version running stock 7.0 (security patch from Jan 1st) without any modifications - I'm using a black theme and fhd resolution, only.

After the last updates, my screen on time went from 5h00 to 2h30 maximum... I'm running the same apps as before and have already done this:

- soft reset;

- hard reset;

- tried only basic apps after hard reset;

- cache partition wipe;

- app preferences reset;

- disabled chrome;

- different theme;

- different launcher;

- other less important things I can't remember right now....

Any ideas on what could be happening here?

mine was eating battery like crazy... 20+ % each night even in flight mode... but i can confirm that its some ****ed up app thats draining it. So after removing the last couple of downloaded apps like HQ etc my phones seems back to normal.

Well, i think and ofcourse i cant confirm that samsung slows phones down with updates and make the standby time shorter just so that you gonna upgrade to a new phone.

I have the dreaded Google Play Services battery drain, which absolutely destroys the battery..

A help thread with Google has so far had them suggesting the wiping data and removing accounts "fix" which stops it for a week, and now it's started again.

I can second that. If you don't have great mobile data reception drain is awful. But this is true for all phones.

I have a month using the s7, and I'm not happy with the performance of the battery, those 3000 mAh do not seem real, the battery drain is too random

use wifi or data, bluetooth for pebble and headphones

Prefect has fast charge, if I go out without the charger I'm in trouble

my old Galaxy J5 Prime has better battery performance, ok is a device with less power

really sad:(

hello, I have got a battery problem too because my phone says " 27%" and 5 minutes after the phone been reboted, so.. our phone has 2 years, i thinks is momento to change but personally, Im waiting for the next galaxy´s generation (s10) or pixel 3 or .......iphone

Wich rom are you using? 7.0 or 8.0?

Thanks
[Samsung Galaxy S7 Real Life Review] frankzero:
Hello

7.0 at that time, now it is updated to 8.0 (sm-930u) now it does not heat up as much as before and some notes of the update 8.0 said that they turned off some background functions to save battery

i only have 3 or 4 days in 8.0

accubattery time estimates

screen on

3h 22m

screen off

36h 9m

17h 5m

70%
[Samsung Galaxy S7 Real Life Review] mcmorariu:
Updated to G930AUCUACSF1 (latest Oreo) a few days ago, and I have huge standby battery drain, but only on LTE!!

Per Accubattery here are my stats (85% battery health) tested over the last 2 nights:

On 4G LTE - 07/07/19

:

Screen OFF: 47% drop @ 5.9%/hr

In Deep Sleep for 7h 26m or 93% of screen off time !!??!!

On 3G (WCDMA) or ATT's "4G" - 07/08/19

:

Screen Off: 6% drop @ 0.6%/hr

In Deep Sleep for 8h 58m or 94% of screen off time

The LTE & 3G tower appears to be the same per Network Cell Info map, but signal strength is approx -100dB on LTE and -90%dB on 3G (LTE & 3G connection is stable as far as I can determine).

I am very certain the Radio firmware is causing this huge drain especially since 3G is so frugal in comparison.

Also, I don't have 3G comparison data to previous Oreo, but LTE drain has been consistent at ~6%/hr.
[Samsung Galaxy S7 Real Life Review] magiin:
Likely for anyone else who recently got forced to the upgrade 3 days ago, standby battery drain is even crazier than it was before for Oreo. At the point where I'll likely wipe the phone and revert to Nougat if I can, or even earlier. Runs very hot standby now, on top of the google play drain. What a mess.
[Samsung Galaxy S7 Real Life Review] kabelgleichung:
Tried with my recent G930FXXS6ESI8 (releases 09/2019):

Drain in flight mode: 0.3-0.4%/h

WiFi & LTE enabled: 0.6%/h

LTE only: 0.8%/h

Hope this helps.
[Samsung Galaxy S7 Real Life Review] magiin:
I never did revert back to nougat, still running Oreo.

G930VVRUACSH1

Phone in general just drains rather quickly, I've felt this way since day 1 with it, and the Samsung force updates that they push I'm not seeing much benefit from.

Still considering reverting to an older version, I just dont know if it's worth the trouble or if I'll see a benefit, other than maybe google play drain being less.

Buongiorno a tutti sentire ho un problema col mio nuovo Samsung s7 edge l’ho comprato da un signore che sfortunatamente dopo aver ripristinato il telefono non sa più il suo account Google come posso bypassare il sistema? Ho visto qualche tutorial su YouTube ... ma non capisco il motivo perché quelli che fanno il tutorial funziona , invece io , non riesco e lo faccio passo passo qualcuno potrebbe darmi una mano??
[Samsung Galaxy S7 Real Life Review] sitnamzug132:
My battery drain was fairly minimal at first-- maybe 1%/hour at most with all background services enabled plus Always On Display. Lately however it's gotten a lot worse. For instance I've barely used my phone today and after about 6 hours I'm down to 75% remaining. Not sure what changed, but I was really enjoying the battery life before and now it kinda sucks. I haven't rooted my phone or attempted to uninstall any bloat, so I'm not sure what could've caused the change.

As a long time Android user quite frankly I find it ridiculous that every device and Android revision ALWAYS suffers from poor battery life.
[Samsung Galaxy S7 Real Life Review] Steffe89:
Most likely the famous radio active bug. I lost 50% today with less than one hour display activity
[Samsung Galaxy S7 Real Life Review] zuke24:
Mine has been draining way too fast in standby.

Always On Display, DND on, I drain at 2.48% per hour.

AOD off, DND on, I drain at 2.22% per hour.

There's no way Doze is working for me.
[Samsung Galaxy S7 Real Life Review] Krautmaster86:
The problem was the Samsung Push Service Update.

(came as auto app update these days, may vary few days and some might not have installed yet, check ur playstore apps)

Go to apps, uninstall (will downgrade the app) -> fine standby drain again. Maybe do a reboot afterwards. I already reported to samsung + rated the app and u can update Post 1 ;)

ur all welcome

Now I'm on my third S7. Still same problem with batterydrain. Yesterday I started this one and right away I got an 73 mb update. I did a factory reset after update and only installed my Gmail, Nova launcher, tesla unread, tapatalk and dolphin. It consumed 60% over night on WiFi. Did a factory reset again this morning and will not install anything now to see if there is batterydrain when my phone is clean.
[Samsung Galaxy S7 Real Life Review] koec12:
Can somebody explain to me what is going on?

This only seems to happen when I am at home. At work I get nearly no drain.

(WiFi & Mobile data are both on, but the phone was connected to a WiFi network during my test)

[Samsung Galaxy S7 Real Life Review] DSC05:
No doubt, it's your wifi settings or something in your wifi network that keeps your device awake. I have the same issue on my LG GPad since cm 13. I searched weeks for the reason. Then I found out that my multiroom wireless speaker system (something similar to Sonos but cheaper) caused this drain and prevents my tablet from deep sleep. It happens only on my tablet (and only since marshmallow), not on my galaxy s5 and as I can say now not on my galaxy s7 too.

So I would recommend that you disconnect any other device from your wifi and test again. I would also use an app like cpu spy so you can check quickly if your device is going to deep sleep while screen off.

[Samsung Galaxy S7 Real Life Review] koec12:
I'm on my own private router. The only thing other than my phone connected to it is my computet via an Ethernet cable. There is nothing (like a Sonos or Chromecast) that could be keeping my device from sleeping.

Could it be my network coverage? At home I only get Edge coverage, so could my phone just be scanning for a better signal all the time? If so, how can I fix this?

And I guess deep sleep is the same thing as doze? If so, I checked yesterday with that GSAM app, and it said it was asleep most of the time. It only woke once for a minute or so.
[Samsung Galaxy S7 Real Life Review] Steffe89:
Could also be your router. I have seen multiple issues mentioned in an Asus router forum related to battery drain. Can you update your router..

Also I have just found out that clearing most recent list every time I leave my phone helps a lot. Flash etc I chrome actually keeps running if you jump out of it.
[Samsung Galaxy S7 Real Life Review] koec12:
I use the router my ISP gave me. It's a Zyxel router, and can not update it (nor flash any custom firmware).

I had every app closed when I tested my idle drain, but on a normal day, I usually don't have that much open anyways.
[Samsung Galaxy S7 Real Life Review] Truth6199:
Try going to <Settings>---<Wi-Fi>----<Upper right corner - MORE>---<Advanced>---<Keep Wi-Fi on during sleep - Select never>. Should help during Wi-Fi consumption and battery life. Curious, Snapdragon or Exynos?
[Samsung Galaxy S7 Real Life Review] koec12:
Does this mean that I won't be able to receive notifications from apps that require a network connection when I lock the screen/it goes into doze? I'd rather let my phone drain som battery then give up notifications. Too bad there isn't some sort of simple fix.

It's an Exynos S7.
[Samsung Galaxy S7 Real Life Review] Truth6199:
You should still receive notifications but it will allow your device to 'Doze' when your phone is not being used. I would def. try it out to see if it helps with the drain. But I can say, my S7 (Snapdragon) seems to do better with draining per hour off Wi-Fi V on it. Not sure why, but the drain isn't hugely different.

Let me know your results.
[Samsung Galaxy S7 Real Life Review] koec12:
I'll guess I'll give it a shot.
[Samsung Galaxy S7 Real Life Review] koec12:
I tested it for an hour this time, and got a much better result. With wifi on during sleep i got a drain of 5.7% pr hour, and with wifi off I got a 2% drain. I might test it again later today and let it sit for a while longer.

On the second picture is shows that WiFi was on during the test, but I think it just didn't update, since WiFi clearly was off when I unlocked the screen. It also says that it didn't doze at all. I don't know if I am supposed to believe this.

Is a 2% drain normal, or is it still quite high?
[Samsung Galaxy S7 Real Life Review] sxtester:
You're misinterpreting the graph. What it means is that your phone did not consume any (noticeable) battery while being in doze mode.

Whether or not a 2% drain is normal depends on what all you have running.

Try turning off Wi-Fi and (that's new with Android 6) Bluetooth background location scanning (both are ON by default even though you have Wi-Fi and BT turned off). You'll find the setting under Locations -> Scanning.
[Samsung Galaxy S7 Real Life Review] waingro808:
First 3 days, my phone was sleeping like a baby. Last night it drained 12% in Airplane mode. Battery info showed Android OS kept the phone awake the entire night. The only thing extra I installed was a widget. Guess I'll uninstall that and see what happens.
[Samsung Galaxy S7 Real Life Review] HeartKiller:
Is there away to schedule phone to turn off over night and turn on in the morning at particular time?
[Samsung Galaxy S7 Real Life Review] koec12:
You can schedule it to restart at a specific time, but I don't think you can make it turn off and then make it turn on again a couple of hours later.

---------- Post added at 07:48 AM ---------- Previous post was at 07:38 AM ----------

You're talking about the second graph right? You're saying that a bar besides the doze tab only appears when the phone uses battery while dozing, and not just shows WHEN it dozes? Are you absolutely sure about that?

I had nothing running when i tested my idle drain. Was a fresh restart as well. WiFi and Bluetooth background scanning were disabled as well.

---------- Post added at 08:05 AM ---------- Previous post was at 07:48 AM ----------

Here is my second 3,5 hour test. This time with WiFi off when the phone sleeps (Second screenshot shows that WiFi is enabled, but it really was not). I definitely got a better result, but I don't know if it is worth giving up WiFi.
[Samsung Galaxy S7 Real Life Review] sxtester:
Looking at it again... think you're right, the graph should be showing WHEN doze is in affect. Sorry, by bad.

What I realize though, in your first screenshot of Battery Stats your mobile signal seems very poor (just 1 bar) where as in the second at least it shows 3 bars. Could this be your eater? Did you try setting the mobile to 3G or 2G only and check what happens then?
[Samsung Galaxy S7 Real Life Review] koec12:
No problem :)

My reception is indeed very bad. I thought I had written this on one of my previous posts. I usually only get 2G, or if I get lucky, HSPDA. It is also very unstable (it drops all the time), so I am almost certain this is my problem, but I came here to see if anyone had any other suggestions, since I can do nothing about my network coverage.

I really don't want to disable LTE and 3G. I only have bad coverage at my house, so turning it on when I go to work every day is a little too much work.
[Samsung Galaxy S7 Real Life Review] sxtester:
Then you have it. If your network coverage is really that bad and 2G is all you get in your house your phone will constantly scan and try to connect to 3G and up. This indeed drains A LOT.
[Samsung Galaxy S7 Real Life Review] koec12:
I am aware of this, but I secretly hoped that someone had come up with some other solution, since getting better reception is a lot more complicated.

I looked into some solutions to my reception problem, but reception boosters are banned in my country (for some reason), so there is not much else I can do.

If one of you guys come up with any good ideas, then I'd like to hear them. If not, thank you for your support.

Battery Drain after inserting Micro-sd card

Hi

My S7 (not the edge version) worked perfectly with about 2 days of battery and mid use for few weeks.

I've noticed that after using it with sd-card, battery started draining faster, but i'm not sure it's the reason.

Can this probably be the cause to that ?

anyone faced this problem ?

Getting about 2 days battery life.

I am using phone just as normal. Also I am not playing games or watching videos on my phone and I am always taking care of switching on 4G, WiFi, Location and Sync only when required:

4G/WiFi - browsing, checking emails, messengers, etc. 4G+Location - gmaps, running with S Health, etc. Sync when want everything to sync - doing that 1-2 times per day. I have "Always on screen" - OFF. Also am using Greenify to force stop some apps when I do not need them running.

So by doing this rituals I am getting my battery staying on for 2 days and two nights:

22:00 fully Charged.

Night+Day

Night+Day

20:00 still some percentage of the battery left.

Charging again for the next cycle.

So basically my top battery consumers are:

Screen: 26%

Android OS 20%

Cell standby 16%

Google services 10%

Device idle 6%

Android System 5%

Browser 5%

All the rest 2% and 1% each.

So I am pretty happy with my battery but still wondering what services/packages would you disable with Package Disabler Pro to save battery life? Are you really disabling all the pink ones?
[Samsung Galaxy S7 Real Life Review] pai.pradeep:
I saw the update, but didn't install it as it was "beta".

[Samsung Galaxy S7 Real Life Review] fredriks:
Don't think they will rollback a software version.

You have to find out what's draining your battery. What do battery information say? You could download gsam battery monitor and see what's draining your battery.

When does it drain?

Standby on WiFi or standby on mobile data?
[Samsung Galaxy S7 Real Life Review] WebsGhost:
until the update my standby was perfect without any drain at all, it took around 1% each hour, now it's taking 2% per hour, i've installed the Gsam only today and there is nothing unusual actually.

I didn't tested on Data yet, untill now the drain is on WIFI

by the way, why you think that they wont rollback the software version?
[Samsung Galaxy S7 Real Life Review] fredriks:
Okej, do some more tests so you can narrow it down a bit. If it's standby on WiFi there are some tips to try in this thread and others.

I really don't think they rollback I software version. There are safety bugs fixed and so on in every update and I don't think there policy is to do rollbacks
