Come on, really ? What can you tell from a screenshot taken at 98% battery, with firmware just installed ? Talk about impatience...:)
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
I flash clean flash, factory reset before and after. I had 50% battery when I flash it, but my settings right, then put it charging, then 100 reboot.

Turn on wifi a little bit before leave home and show android system. But i reboot again after the screenshot and im on 4g doesn't show yet. Only android OS, because android system is higher with wifi.

Edit.

Android System could be a little better but android OS is much worse.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
So Android System drain is minimal, doesn't even show up, just as expected. Android OS is high because the phone has not stabilized after reflash (still downloads software updates, etc.).
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Android System is on 4% now, and is low because im on 4G.

And in my phone is nothing downloading.

I have all settings right.

Android System could be better in APC8 but Android OS is Better in APF2.

Battery is the same.

Later updating again to APF2.

You could keep with ACP8.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
It would be great if you would have enough patience to really wait at least one full charge...as you have seen, APC8 solves the issues.

If you update again, at least use the new APF8 firmware and tell us how it works...but again, if you post hunderds of screenshots and don't wait at least one day before drawing conclusions you will just fill this thread with useless information.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
I see only you post good information, not other.

I join here to learn and help from what i know.

And i know how test my phone, i have always all days the same usage with my phone, and i can see the differences from firmware to firmware, i know every people usage is different.

But let's keep the calm here.

I will leave ACP8 until weekend and try new APF8.
[Samsung Galaxy S7 Edge Questions and Answers] koziakauzu:
From what I understand, Android os needs time to calibrate, optimize, etc. After reset, purchase new phone, you always need to wait few charge cycles and 2-3 days to see everything settle down. Or maybe that's an urban legend? If not, all these 1h tests are indeed pointless.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
After you have set your settings and charge the first time, there's nothing to calibrate, start using, start draining.
[Samsung Galaxy S7 Edge Questions and Answers] hasher22:
Hello,

When I first purchased my phone, 1 month and it's all good. Battery was amazing. Now android system is killing my battery.

Though, I fixed the solution temporarly which is clearing the System Cache (Through boot menu, hold down volume up, home and power on buttons when the phone is off). For about 3 days, android system was at the bottom of my battery usage. Now it has creeped back to the top at 40%+ usage battery!!!!!!

Before I used to go to sleep, just turn off my screen and approx 10% battery would drain. Now 60%+ battery would drain when I sleep when "android system" is effecting my phone.

Yes, I tried all the methods and apps you all can think off.

I even factory resetted my phone, clear the system cache then factory resetted it again through boot menu.... still no luck.

android system is a biach!!!!! Google needs to fix this.....
[Samsung Galaxy S7 Edge Questions and Answers] sahil sharma:
60 % overnight drain is a lot. I believe there is some other issue.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Definitely something going on there if you have 60% drain at night. This phone has pretty ****ty battery life (SOT anyway) compared to it's competition stock, and does okay compared to other stock flagship phones if you tweak the hell out of things and do all you can to save battery but 60% is definitely not normal over the course of a night. I'd get it looked at. That even seems too extreme to be an app.
[Samsung Galaxy S7 Edge Questions and Answers] theJSN:
I think we need to keep our sights set on the fact that its always showing a total of 100% of the usage to the point that you checked your battery status. So If you check it shortly after taking it off the charger and its done nothing but background processes because you haven't look at it much then sure its going to show majority usage to the android system. As you pick it up and use it, your screen time will start to log more usage. If you were to boot up an intensive game and play for a while, you will quickly see the android system percentage go down, with the game and screen percentages go up. Keep this in mind when you are looking at the percentages. a report 60% of android system isn't that its going to consume 60% of your battery for the whole day, its going to balance out as you launch other apps and use the phone.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
He's not saying 60% of usage was android system. He's saying his battery drains 60% overnight. "Before I used to go to sleep, just turn off my screen and approx 10% battery would drain. Now 60%+ battery would drain"

So say he goes to bed at 100%, that means he wakes with 40%. You're right on the android system though. Those measurements are made by the majority of use. The more you use it, the lower system falls on the scale.
[Samsung Galaxy S7 Edge Questions and Answers] theJSN:
Oh yes I agree there is a problem with the user with the drain, I was more talking more about the thread. Honestly I didn't think i was having a problem until I saw the forum title then checked my android system and got alarmed when I checked and saw my android system high as well. I didn't want others to fall into the same misunderstanding i had, now that i can see its a sliding scale and always adds to 100% I can see my phone is operating normally, if I don't use my phone much, my android system is way high at the end of the day. If I play a game for hours, the game and screen become the highest with android system extremely low in comparison.
[Samsung Galaxy S7 Edge Questions and Answers] hasher22:
yes this is correct, I downloaded battery monitor apps, greenify etc and "android system" is always #1 in high battery consumption.

Update: I think I have fixed the problem. Since I was getting more than 60% battery drainage when I sleep (approx 8 hours of phone standby). Now my phone seems ok, 3h 22m on battery and I'm @ 78%. Usually my battery would be at about 60% by now or less

Here's what I did;

1 - backed up my phone through samsung smartswitch, PC version

2 - factory reset my phone through settings

3 - DID NOT go through the start up wizard, instead I went into the boot menu and cleared the system cache

4 - In the boot menu again, factory reset the phone again that way

5 - In the boot menu again, cleared system cache

6 - In the boot menu, reboot the phone

7 - Went through the startup wizard as normal as a NEW PHONE, did not restore my stuff through my gmail account

8 - restored my phone through samsung smart switch

All seems well now..... just a waiting game to see if my battery will drain again fast.... :(
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
I would recommend factory reset and do NOT install any applications but do enter your Google account, test the drain without any app installed first. There is no way any firmware release would produce 40% drain over night, (unless your Wi-Fi router and phone are not compatible somehow. Also test with GSM only, Wi-Fi off).
[Samsung Galaxy S7 Edge Questions and Answers] hasher22:
My phone seems ok now. Just ok :D after all that factory resetting I've done

In the next couple of days, if my phone drains more than 40% - 60% with the screen turned off when I sleep (I don't charge my phone overnight), then I will do this! :D
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Though keep in mind with cellular data, if you live in an area with a poor signal it will melt battery life away rapidly. Wifi is better in that case. When at home, we have very poor signal strength. My phone will do good to get through half a day idling at home. Not even touching it. Putting it on wifi and turning off cellular data resolves this. When at work or in the city running errands where signal strength is good, battery life is improved even over wifi when on cellular data. Whether it's wifi or cellular data, a bad connection will murder your phone's battery in a hurry. Always use the one with the best connection unless both are top notch, in that case, us cellular data.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
This is why I use the My Places edge feature

- force WiFi ON when at home (based upon geographic location) where phone has weak signal

- elsewhere force WiFi OFF since I do not regularly have any WiFi access *anywhere* outside home (life in the digital backwater...)

Luckily I have terrific signal at work.

This at least automates dealing with signal strength variation.

Hi,

I am having an issue since I tried to downgrade my firmware. I had battery drain as well after I installed the latest firmware, so I installed the old firmware (April) through FlashFire and my phone now got stuck in recovery mode with 'dw-verity verification failed'... Odin does not recognice the phone and any re-boot ends up in recovery mode with the failure message. I also tried 'wipe data/factory reset' but nothing changed. Can anyone help please?

<Edit>

I forgot to mention, I have a TWRP backup on my SD card but as soon as I try to access sd card in recovery mode it says 'update from external storage is disabled'.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
What odin version are you using?

Coud be corrupted the file.

Try to download again or from sammobile.
[Samsung Galaxy S7 Edge Questions and Answers] scrato:
I am using Odin 3.11.1 but the phone is not beeing recognized at all. It even says 'update from external storage is disabled'. The firmware must be fine cause it was my previous version which worked until I updated to the latest version. I dont know how to get back to TWRP or at least reinstall regulare firmware as I cant access the phone. Not via sd card and not via ODIN or KIES.

On top of 'dw-verity verification failed' it says 'Supported API: 3'. Any idea what that means?
[Samsung Galaxy S7 Edge Questions and Answers] crystal13282:
I also have os android battery drain.

Thanks
[Samsung Galaxy S7 Edge Questions and Answers] kitch9:
Has anyone tested the effect of NFC, I've turned it off and rebooted this morning. Android System is now at 15% instead of the usual 25-30%

Early days, but I'll keep an eye on it.
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
I tested it, no real improvement.

I have from one person that his phone finally sleeps with de APF5 update. Haven't tried it myself, but curious now. Is anyone on that update?

How

How do i downgrade it? Is any tutorial available for the same. Also please post a download link and necessary software
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
As expected my test only prove my theory,

In ACP8 in 4G have the android system very low but the android OS consume for both

I had at 50%battery Android OS 530mAh Android System 70mAh,

Now im testing APF5 android system is 13% 260mAh and Android OS 14% with 270mAh.

With better sot.

Only need to know in wifi only.
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
Interesting info, you reached 50%battery with the same standby time?
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Cell standby is around 15 minutes 200mAh

Usage time is around 10h on battery.

Now i have cell standby 10 minutes 90mAH
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
How much SoT until 50%? (only 4G right?)
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
ACP8 normal until 50 around 3hsot in 4G.

Today i have now 4h.30m, but to be honest like i said in other post first 2 3 charges after factory reset is always better.

I will test until end of the week.

ACP8 could be better for wifi but not to 4G.

And newest updates are more smoother.
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
Guys my Android system is stable now. It's at 14-15% instead of 35-50%.

I tried to flash the S7 Edge with odin with the firmware of a S7 not Edge.

So i got a fail in downloadmode for flashing.

The S7 Edge was booted several times from download mode.

Since then android system is 14-15% for 2 days now with the newest update that i got in June (Belgium).
[Samsung Galaxy S7 Edge Questions and Answers] julien32:
I was on KING_ROM_S7_EDGE_V8 [apf2] last week and my battery life was not good, the phone was getting really warm for no reason just browsing around.

I am now on BasicPlus 1.1.1 [PC8] since 3 days I can tell there is a huge difference, the phone doesn't get warm and the battery life is just amazing, without any tweaks I can get 9h SOT.

here is my comparison between KING_ROM_S7_EDGE_V8 vs BasicPlus 1.1.1
[Samsung Galaxy S7 Edge Questions and Answers] crystal13282:
I just done official update APEQ on my S7 brand TIM (Italy).

System Android is about 13-17% now (instead of 17-25-30%).

But I noted major consume in 4G now!

Someone knows if APEQ update is before or after ACP8?

I read that ACP8 is the only one with System Android down 7%.

Thank you.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
APF5 android OS higher too.

APF2 XEF still the best so far for me.
[Samsung Galaxy S7 Edge Questions and Answers] suvasishngn:

How is it poor if it's lasted me the whole day?
[Samsung Galaxy S7 Edge Questions and Answers] drummerman:
Whilst I appreciate that every individual installation has differences I find it difficult to explain the vast differences in Battery time folks experience with stated similar usage and applications ... .

I don't mean to gloat but for me battery life has been outstanding on this (non-rooted) phone as I have published a few days ago.

I hope you guys can sort your battery issues out.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Well, this phone lasts two whole days (48h) usually, with 5-6h SOT, look at some previous posts. There is no reason to have "one day" expectations in 2016.

Brazilian apf8 is pretty good

Im using that with australia unbranded (xsa) csc and so far not much difference to apc8 (battery life or any other services drain)

[Samsung Galaxy S7 Edge Questions and Answers] Galactus:
APC8

4G Only - 1 bar signal 90% of the time - 13 hours on - 3 Hours SOT

Auto Brightness - Mainly between 20% - 50%

Android OS - 9% -157mAh

Android System - Not even on the battery list

60% battery remaining

With WiFi, basically 7-9 Hours SOT, close to two days on (typically 40 - 45 hours on)
[Samsung Galaxy S7 Edge Questions and Answers] aksyong:
How do you guys get 48 hours with 5-6 hours SOT? My S7 Edge (Singapore SM-G935FD, Firmware G935FXXU1APEQ) barely lasts 18 hours with only 3 hours SOT. I have Location, WIFI, 4G, Sync always on.

If it matters,

Google location is off

Google Now is off

Google Backup is on

Google Photo backup is on only when charging

Samsung backup is on

I have Facebook and Instagram pre-installed

Auto-brightness is on, I don't tweak any of the brightness value

Display mode is set to Basic

The only three commonly use apps is Reddit is Fun, Spotify (offline) and Tiny Tower.

Isn't android system using up your battery?
[Samsung Galaxy S7 Edge Questions and Answers] aksyong:
Android system consumes 17% while android OS consumes 10% . I don't know the difference between those two, how do I reduce those consumptions?
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Sadly, by turning off most of those backup and sync features that you shouldn't have to turn off if things were done properly with regards to this phone. But since either Google or Samsung or both can't sort their jobs out, you have to. Or deal with the battery life being abysmal. To start, turn off location unless you absolutely require it. Many people do it anyway for privacy reasons, and apps like the weather can have your location manually put in. If you can't turn it off, people have reported success with changing it from wifi, bluetooth and GPS to just GPS. Also turn off wifi and bluetooth scanning in the location menu. They scan constantly whether you have the antennas on or not.

Next, turn off either wifi or 4G. If you have a poor 4G signal it uses less battery to use wifi. If you have a great 4G signal, that uses less battery than wifi. Not much less, but it does use less battery. Pick your connection accordingly. Generally you want one or the other but not both. The reason you pick the one with the stronger signal is that if your service is weak, your phone will constantly be searching for a better connection. Also, in the data menu under 4G, turn off Enhanced LTE services if your phone has that option. This uses more battery than just your basic 4G/LTE connection. Next, turn off Google backup, all reporting (for Samsung and Google), turn off all auto updates (Play Store and Samsung apps), and photos. It sucks that you should have to turn off any of the critical things mentioned here. That kind of had me annoyed as with the phone I had previously (iPhone 6s Plus) I had a smaller battery, had to turn NOTHING off and was getting 10-11 hours SOT and a couple days standby if used lighter (around 7-8 hours SOT). It seems at the very least with all features on the S7 Edge should be able to crack more than 3 or 4 hours. Also using Greenify (the paid version if that matters) for aggressive doze and disabling almost everything except messages, Whatsapp, and Telegram.

Doing all the above as well as turning off all advanced features (Pop up gesture, Smart Capture, palm swipe, direct call, smart alert, easy mute, smart stay, edge features, basically everything that was beneficial in buying the edge except the camera) has given me between 6 and 7 hours SOT depending how I use it. It's enough to get comfortably through a day, but it's pretty frustrating that doing so requires disabling damn near everything overall, and absolutely everything unique about the Edge itself.
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
Lol whut? I only have google back up turned off and got 41 hours stand by and 5 hours screen time on 1 battery charge.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Here's a cookie! Not everyone is so lucky, a massive number of people have to follow the above steps collected from several posts across this site (posted so often by so many people specifically because the battery life is so ****ty without it). And 5 hours SOT is pretty bad given the size of the battery in this thing.,..
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
5 hours since the new update. The first stock firmware was the best firmware there i got 7-8hours screentime.

So if you wan't those features flash your phone to original firmware and you are set.

For me the stand-by is more important then screen time.

That way i don't have to worry oh no i have to charge the phone soon...

I don't konw about an ACP update. Its:

APB(F)

APD

APE(Q)

APF

The third letter follows the alfabet :) So next one will be APG. I you mean APC, it probably is before APEQ then :)

Well most people are getting great batterylife. Only some of us don't. What I find strange is why those people post here. Maybe some are trolling, or just happy to post that they are really happy with their phones.

By coincidence I just met the samsung representative for belgium :P. So I discusses the problem. She called the head of their tech division (belgium one) and the problem isn't known there. She would report the problem when she would be back @ headquarters. She adviced: wait for the next BIG update. She said that there was comming one soon. If that doesn't fix the problem, go back to the store with the phone.
