Yes this needs to come to exynos unlocked versions I can't deal with this standby drain any longer!
[Samsung Galaxy S7 Guides, News, & Discussion] loth77:
on my not rooted, italian, no brand exynos SM-G930F i have noticed that everytime, after i charge it completely, it doesn't go deep sleep anymore and drain about 3% every hour without even touching it.

i must reboot the device and then it goes again in deep sleep mode.

i had similar problem with my previous devices, but this time i don't want and can't root (at least for a while), so i can't really check wakelocks and so on... what can i check to find what keeps my mobile away from deep sleep?
[Samsung Galaxy S7 Guides, News, & Discussion] hariskks:
Hello to all,

I have the Galaxy S7 (SM-G930F) for a week now and currently on build/PDA/CSC: G930FXXU1APD1.

My main issue with my battery is that cell standby is on the top of my battery usage and way higher than anything else. I am a very moderate user so the mobile network is on 2G (I do not use 4G a lot) which has time without signal 0%, all 'smart' stuff are off, wi-fi scanning is also off and all other toggles off also (bluetooth, location etc).

Is this behavior normal? Is anyone else experiencing the same?

I had in the past both the S4 and the S5 with same usage pattern and always the cell standby was way lower while the phone was in standby mode (around 5-7%) and device idle usually on the top. Now with the same standby times the cell standby is for example on 37% and device idle on 24% (this is with just 1 hour SOT).

Any suggestion would be apreciated
[Samsung Galaxy S7 Guides, News, & Discussion] Kamekazegoldi:
Hello folk,

I am experiencing the same. After updating to G930FXXU1APD1 my battery life has become horrible.

As you can see on the pictures Android System & Android OS are draining like 40%. And then there is this f****** Google Services in addition.

Even with my S6 I had a MUCH better battery life. I am even considering rooting it now :(

Does anyone have an idea how to solve this problem?

Thanks
[Samsung Galaxy S7 Guides, News, & Discussion] fabiok81:
The same for me with PD1 Exynos version. The phone didn't go in deepsleep. I downgraded the Fw in PB9 and now is right. I'm waiting for a new upgrade
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
Would you have a link to the old firmware? I've tried searching for it on sammobile but all I could find was the newer one unless I'm missing something
[Samsung Galaxy S7 Guides, News, & Discussion] fabiok81:
My phone is Italian branded Vodafone. You have to see what is your model and your CSC. Download an apk called phone info.. If you'll have problems I'll try to help you but we need those codes
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
Does this help?
[Samsung Galaxy S7 Guides, News, & Discussion] fabiok81:

Thanks man but one question, doesn't flashing this Rom delete all your data? :/
[Samsung Galaxy S7 Guides, News, & Discussion] fabiok81:
In that firmware you will find all the four files to keep into Odin. You can also choose between two CSC files, a normal one and a home_csc one. Using the normal CSC file you will wipe everything. I read the the other home_csc shouldn't wipe your phone but I'm not sure

1 day and 13 hours off the charger, mostly on wifi with some hours of data, over 6h of screen on time and still 22% battery...

nothing else to say, battery is a beast in this phone.
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
Exynos? Snapdragon? What firmware you on?
[Samsung Galaxy S7 Guides, News, & Discussion] -Ric-:
unlocked Exynos running stock non-rooted MMB29K.G930FXXU1APD1, network mode changed to 3G/2G Auto and location off, other than that, everything turned on and running.
[Samsung Galaxy S7 Guides, News, & Discussion] seanie2322:
Interesting. That's the firmware from the April update that appears to be causing a lot of battery problems with exynos models including mine.
[Samsung Galaxy S7 Guides, News, & Discussion] -Ric-:
Well so far no issues with mine, everything is running far better than I thought it would :D

WiFi draining issue

WiFi drains most of my battery life. Is that normal? I just turned off some settings related to wifi under Location, hope will fix this problem.

Any sugestions what can i do?

Pls help
[Samsung Galaxy S7 Guides, News, & Discussion] SilviuMik:
Pretty happy with battery life. Mixed usage mostly talking in this period. Both SIM on 2G and only when needed 3G . Wifi / location off and when needed started them.
[Samsung Galaxy S7 Guides, News, & Discussion] HuskQi:
Out of nowhere I'm getting awful battery life (1hr 40min SOT consistently).

One day Android Systems will sit at 40% usage, and on other days it will be Google Play Services. No updates done recently, not sure what changed as I was getting 6hr SOT previously.

contemplating a reset -.-

I have APD9 baseband, I was having superb battery life and I don't know why I decided to try package disabler and then I got force closes. I tried Uninstalling and coming back. And now my android system is above 30% and battery got worse. I did a factory reset but that didn't work yet. What can I do?
[Samsung Galaxy S7 Guides, News, & Discussion] Lucoso46:
Install the APD9 firmware by odin
[Samsung Galaxy S7 Guides, News, & Discussion] Facuu:
Don't i already have the apd9 firmware? Wouldn't it be better to install the latest firmware available?
[Samsung Galaxy S7 Guides, News, & Discussion] HuskQi:
Installing official firmware via Odin wouldn't trip Knox would it?
[Samsung Galaxy S7 Guides, News, & Discussion] fauxpax:
It will.

Use Smart Switch recovery to reinstall stock firmware without tripping Knox.
[Samsung Galaxy S7 Guides, News, & Discussion] skivnit:
Lol what??no it does not.
[Samsung Galaxy S7 Guides, News, & Discussion] fauxpax:
Have you tried? I've tried on a couple of Samsungs and it always did.
[Samsung Galaxy S7 Guides, News, & Discussion] Jairus24:
It will not trigger the Knox warranty as long as you are flashing the official and untouched stock firmware (Example: firmwares that are downloaded from Sammobile and flashed through Odin). Knox are only triggered if you change some files in the system partition (Example: rooting or flashing a pre-rooted rom). If you're going to ask me if I have already tried it, yes I already done it and Knox warranty is still valid.
[Samsung Galaxy S7 Guides, News, & Discussion] fauxpax:
I was talking about unmodified stock firmware too.

Since two people claim it doesn't, perhaps I'm not the best Odin flasher.

Please let me know if it remains 0x0 for you after you flash.

And sorry if my advice was wrong.
[Samsung Galaxy S7 Guides, News, & Discussion] HuskQi:
After having so many issues with the S7 at purchase I can't afford to void warranty by tripping Knox even if there's only a small chance of it happening so will take it to a Samsung store and have them do it as they did with my S6.

As a last result, I could always just wait for an update as originally intended.
[Samsung Galaxy S7 Guides, News, & Discussion] fauxpax:
Hope people won't lynch me for scaring you ;).

Samsung's own Smart Switch is a fully safe way of stock software reinstall and it's a no brainer, so you might want to try it in the meantime anyway.
[Samsung Galaxy S7 Guides, News, & Discussion] HuskQi:
haha that's fine~ better safe than sorry.

I'll definitely try Smart Switch when I get the time. I hadn't even thought about that until you mentioned it!
[Samsung Galaxy S7 Guides, News, & Discussion] skivnit:
I am stock and flashed all fw updates through odin it doesn't trip knox. Flashing a custom recovery or rom trips knox
[Samsung Galaxy S7 Guides, News, & Discussion] Facuu:
Hi guys, quick noob question here. I haven an exynos unlocked, no root and with no carrier at all. I bought it from amazon and it just installed the apd9 as soon as i bought it.

I could donwload any firmware from sammobile, expecting the newest to be the latest one, and flash it through odin on my phone?. How do you know which one is the latest one? Will i have problems with my phone's radio or anything like that? as i was looking for people questioning about csc and such. According to what i could find, apd9 is the latest firmware from southafrica?

I'm in Argentina so the phone is not even here yet, so i guess flashing another one is ok with me. Are all the firmwares from sammobile stock and no carrier bloated?

Also i don't understand the way they call them, as i've seen people say they got the last update and it was called APD1, while mine is APD9 and that "should be more updated if i look at the numbers"

Well, i hope someone could give me a little light here, as i'm very used to flash custom roms but no stock roms lol.

Thanks in advance!
[Samsung Galaxy S7 Guides, News, & Discussion] Facuu:
Where can i find the APC8 build, which doesn't have the android system and android OS drain for the s7 flat?

Thanks
[Samsung Galaxy S7 Guides, News, & Discussion] omeryounos:
I have flashed tens of times in Galaxy S5, S6 & S7. Untouched stock rom flashed through Odin never trips Knox. May be you need to check the process steps or the Roms before proceeding...
[Samsung Galaxy S7 Guides, News, & Discussion] HuskQi:
SmartSwitch seems to restore the current FW, so guess I'll have to go via Odin.

The usual process I follow is: Get FW from SamMobile, Odin (F.Reset ticked, Auto Reboot unticked), PDA flash, wipe cache and reboot.

Providing the FW I download is fully stock, I suspect this is the correct method to use so as to not trip Knox?

Sorry I thought you had it just one day.

Can you post a screenshot of your battery screen?

Here it is. 3 days ago the SOT was my top in battery drain. After the update its like this.

Should I be using Package Disabler Pro or EZ Package Disabler?
[Samsung Galaxy S7 Guides, News, & Discussion] Security555:
You are not alone, it is Samsung, think twice about software update if you are satisfied.

The only solution is to turn off google account backup or to restart your phone immediately after unplugging the cable
[Samsung Galaxy S7 Guides, News, & Discussion] Security555:
You don't need any app, just go to the settings-backup and reset and turn off Back up my data, that's it.

If you need backup, restart you phone everytime after recharging/pulling out the cable, but this doesn't work 100%
[Samsung Galaxy S7 Guides, News, & Discussion] Security555:
Your phone seems to have something special.

I would suggest to install Gsam and wakelock detector to monitor all apps activities.

For sure you'll find an app draining your battery
[Samsung Galaxy S7 Guides, News, & Discussion] tampaocongelado:
Gsam already installed, but wakelock detector is only for root. Do you have Any app to detect that?

In gsam i can see Android os in the top of the list.

[Samsung Galaxy S7 Guides, News, & Discussion] filidib:
Hi guys, I'm quite disappointed with the battery life of my S7 Dual Sim G930FD.

It's the best phone I ever owned performance and hardware wise, but it won't go beyond 13 hours of usage with 2.5 SoT!!! I disabled Google Backup, AOD, Smart Scanner, NFC, Bluetooth is OFF, I'm mostly in WiFi or good strength 4g, screen brightness set to auto. Very few apps installed, regular use and no games. I see people getting 5+ hours of SoT and almost 2 days of stand by, there must be something wrong with mine! Had it for 10 days. I've been reading on all forums but nothing seems to work. :(
[Samsung Galaxy S7 Guides, News, & Discussion] Hi-TechUp:
Can you make some Screenshots?
[Samsung Galaxy S7 Guides, News, & Discussion] filidib:
Here they are, and I don't know why the statistics don't match between Gsam and the Settings battery manager... on another screen, not posted, there is a 30 minutes difference in SoT between the 2!

Poor before Update, worse after

Hello folks,

battery life was never the best for me till I got my phone.

Till now I refused to root it because of loosing warranty and having to set everything up again.

But after the latest update the battery life has become insane bad.

Could you please give me any advise how to figure out what is causing this issue and if there is any way to fix it?

Please tell me if you need additional information.

Hello community,

I will show you my battery data in the pictures below. Do you think it's average? Because most of you get up to 7h SOT but I only have around 4 to maybe 5. I hardly make it through the day. Furthermore my standby consumption is OK at night (around 0.5-1% an hour) but when I'm at school (where my S7 is also just in my pocket) it's horrible (4% an hour). I have the Always On Display On but it turns off in my pocket and at night.

Can you help me please?

BTW: I have the exynos version

Thanks in advance !

Battery life

Chipset: Exynos

Battery Life photos attached.

I have no idea whether my battery stats are normal or not, especially given how much Google Play Services is using. I am not rooted, and have disabled bloatware that I am not using. I have only enabled sync on the necessary accounts and have tried my best to adjust settings accordingly. Any ideas? Many thanks from a newbie.
[Samsung Galaxy S7 Guides, News, & Discussion] Maidenx:
Same here! Google play Services is eating my battery!
[Samsung Galaxy S7 Guides, News, & Discussion] falmay:
Uninstalling Google Play Services' latest update and reverting to the stock version has (for now) shown an improvement in battery life.

Not sure what else I can do, but will post results later.
[Samsung Galaxy S7 Guides, News, & Discussion] Maidenx:
but Google Play Services doesn't update automaticaly?
[Samsung Galaxy S7 Guides, News, & Discussion] KoRoZIV:

[Samsung Galaxy S7 Guides, News, & Discussion] falmay:
I am not sure but I found through the Application Manager that it had a version that was not its stock version, and reverted it back. So far sitting on 17 hours 40 minutes with just over 30% battery remaining.
[Samsung Galaxy S7 Guides, News, & Discussion] nashy10:
I have the exynos chipset, and latest version of Google play services. Doesn't even appear in my stats... I think it's mostly dependant on how much you use your GPS, just turn it off when not needed.

Sorry, I can't honestly believe these SOT. 20% battery left and more than 8 hours of sot???

Need much more data and screenshots. Which ROM? Auto brigtness? What kind of use? 4G? Bluetooth?? I see the icon... Greenify? Servicely?.... screenshots of total usage in hours with graphs...

I always see these kind of times, but I am not able to do even 4-5 hours... with no wakelock at all, perfect signal, auto brightness.

[Samsung Galaxy S7 Guides, News, & Discussion] quarintus:
So could someone try this out.

Yesterday I disabled: google services framework, google play store, and google play services. (if i couldn't disable them, I would delete al storage). Then I would activate them again. The apps are now back to their first versions.

Last night, I only lost 2% battery in 8 hours. So I need some other people to try this out en see if their standby drain goes away.

NOTE: android system and android OS are still high, because when not in sleep, they are still draining...
[Samsung Galaxy S7 Guides, News, & Discussion] ccl2003:
Here's a follow up on my previous SOT screenshot. Just look at the apps used watching videos using VLC for more than 5 hours, browsing for about 30 minutes, watching streaming videos on Iflix for about 2 hours, and Youtube for about 30mins with Bluetooth on while connected to my Logitech X50 BT speaker. :)
[Samsung Galaxy S7 Guides, News, & Discussion] Malik828:

[Samsung Galaxy S7 Guides, News, & Discussion] XDevOS:
You can charge the phone halfway and unplug it and it will not reset the screen on time. I did that and I got 9 hours of screen on time.
[Samsung Galaxy S7 Guides, News, & Discussion] ccl2003:
Unfortunately, I never did such as thing. I was very surprised too with my S7's battery life and I don't care if no one believes it or not because it is exactly what I experienced. As they always say, people believe what they want to believe.

Second day, my battery life is doing much better!

Disable google play, google services and google framework. Than enable them again. Mobile standby is now actually in my battery usage, finally it ís sleeping when the screen is off :)
[Samsung Galaxy S7 Guides, News, & Discussion] wow *wink:
Auto Sync?
[Samsung Galaxy S7 Guides, News, & Discussion] falmay:
Yes I am using Auto Sync. So far after reverting to stock Google Play Services. Now up to 1 day 6 hours with 33% Screen use maybe 5 hours or so SOT.

I need Auto Sync for my Gmail/Microsoft Active Exchange mainly, with other accounts turned off (e.g. Whatsapp/Financial Times/Soundcloud etc)
[Samsung Galaxy S7 Guides, News, & Discussion] Silvers91:
I had a pretty bad battery life the first day but this second day is great and I imagine it's only going to get better! Was using the phone constantly without stopping, lots of whatsapp, twitch, some netflix and browsing, some light gaming.. at the end I ended up with almost 7 hours of SOT, this is so crazy (I didn't charge my phone halfway, you can check the time stamps and the graph).

I'm currently satisfied.

PS: Disabled NFC, GPS, Bluetooth, brightness at 50% (sometimes at 100%), disabled all bloatware using Package Disabler Pro.
[Samsung Galaxy S7 Guides, News, & Discussion] wow *wink:
Yeah I had the same thing. And google is downloading a lot of things the first few days. Mine has settled down.
[Samsung Galaxy S7 Guides, News, & Discussion] nashy10:
Tried your recommendation there, was normally averaging 4 and a half hours of SOT. now, even with a reboot halfway through the day I got this, nice tip. Not updating Google play services anytime soon! Sync, and GPS on as well as AOD.
