Hi everyone....

I have recently faced the battery drain on my phone.... it is tok much even if i dont use my phone... it is an exynos version. 935fd... in first two weeks it was just stunning but now it has starting to get low faster than usual. The main things eating battery are android and screen. Tried wiping cache partition but no use.... also tried to reset it... nothing happened... overnight drain is 10%.... am confused... also tried usi g greenify.... but it increased...

Ps: am not rooted.

Any suggestions plz!

Hi everyone,

When looking in app wakelocks (using gsm battery monitor or wakelock detector), I notice the facebook app (com.facebook.katana) is waking my device a few times. It would appear normal if i had not disabled it, but i did... I tried disabling it with package pro disabler, but still some wakelocks, then i enabled it, went to the app setting and disabled it from there. I still have wakelocks.

Does anyone have any idea why and how to definitely get rid of it ?

(stock 7.0 rom, unrooted)
[Samsung Galaxy S7 Edge Real Life Review] xenonpro88:
August Patch destroyed my battery, Google Play services and Android System average wakelocks jumped from two digits to nearly 4 digits in half a day. Tried everything but nothing helped...
[Samsung Galaxy S7 Edge Real Life Review] chrisclaytonnz:
I thought this was just me.

I've changed from Facebook to Facebook Lite, Messenger to Messenger Lite, turned off Wifi and Bluetooth scanning. I lost 12% from 10pm to 6am last night and about 3% per hour sitting idle on my desk today.

Only since August (and September) patches.
[Samsung Galaxy S7 Edge Real Life Review] xenonpro88:
My device used to easily last over 48 hours, now it's barely staying alive after 30 hours :(

I don't even use Facebook/Lite. I have never enabled Bluetooth, no Location services, no scanning, no NFC, Brightness always less than 30%, I have literally nothing running other than my good ol' Adhell2 + Substratum that had been serving me fine since previous patches. I don't even use mobile data and always on full signal set to 3G. Location history disabled, No OK Google Detection, no smart-sensor nonsense (smart stay smart lock etc)

On idle it drains 2.5-3% per hour (same as you) with extremely high wake locks and held awake, after deeper investigation the Google Search/Now App is the cause of the wake locks and everything. I've cleared its data and whatnot, though nothing improved.

Anybody has information on "ConnectivityService" & WiFiWatchDog wakelocks? I couldn't find the source of it, it used to be under a minute over days of use but now it's way over 10 minutes within a day. My WiFi is working fine and there's no scanning, dropped signals, etc. Smart switch is disabled, all apps in "Always Sleeping".

Disable Location history in Google app. Go to the app, swipe from the left to reveal the navigation drawer, go to Settings/Account/Activities and then disable location history.

Hi everyone,

I just have one quick question please : is it normal/okay to have Android system as first battery sucker at about 16% (Kernel - Android OS comes 2nd, with 11-12%) ? It's what i get in GSam Battery monitor for a few days, i'm not sure it's what i should be getting, and i'm not sure if the device ever goes in deep sleep either.

Thanks in advance

Better battery stats (there is a free version on XDA) or GSAM battery monitor
[Samsung Galaxy S7 Edge Real Life Review] KLit75:
I was getting about 12% drain overnight. So last night I turned off location, sync, Bluetooth, nfc, disabled wifi direct and made sure I quit all apps before going to bed. Somehow this made it go from a 12% drain to a 16% drain!

The battery life is really frustrating overall. I have mid range phones from 4 or 5 years ago that I can leave on for a week and still have a 20% charge. Obviously I don't expect that here but I think even 4% in 8 hours standby is pretty close to unacceptable. BTW I had already factory reset this phone 5 days ago.

Anyone have suggestions?

A little off topic-sometimes twice a day, sometimes once a day this phone comes to a complete stall. It gets really laggy. If I press the home to turn off the screen it can take 30 to 45 seconds to wake it up again. I usually reboot, wait a few minutes and its back to normal.

Im running stock u firmware from September unrooted. I bought this phone in late July.
[Samsung Galaxy S7 Edge Real Life Review] KLit75:
Last night I put it in extreme power saving mode (customized to allow AOD). The phone dropped 8%(100-92) from 12:30am to 8:00am.

Something is definitely wrong here. Awhile back someone told me doze is not working on ufirmware, then someone else told me it was absolutely working. It seems like it's working. When I check there are no apps waking themselves up except for the ones I allow. Regardless, I don't think that matters because before I go to bed I force stop every app under battery>save power

What are the odds I have a defective battery?
[Samsung Galaxy S7 Edge Real Life Review] naveed1321:
Bro which Rom and kernel do you use To get such better results.
[Samsung Galaxy S7 Edge Real Life Review] bodomfan:
My battery drained 21% overnight that's really bad,should I factory reset?
[Samsung Galaxy S7 Edge Real Life Review] Eggleston11:
I dont know when this thread became a "help me! my standby drain is awful" thread. But anyways, always happy to help (yes, I am bored lol).

That may work, it MAY be system. However, there may be other culprits. e.g. an app that keeps waking up your phone. even if you factory reset and reinstall that app, you will still lose heaps of battery. my advice - find the cause and see what the biggest drainer of battery is. Use BBS, Gsam or even the one on device maintenance, although crude (cough crap cough) is enough for me most of the time.

If it does happen to be an app, greenify/ icebox/ uninstall/ whatever the app and you should save juice.

I personally suspect it's either BS or they did not do a real life test e.g. airplane mode, standby. Just by having LTE on would use ~1% overnight.

The fact that they provide no evidence or detail and has never replied to anyone asking for proof/ "how tos" also compounds my suspicion.

I will stand corrected if I can have proof and hopefully a guide though.

Li ion battery drains quite fast from 100-90%. I'd try starting from 80 or 70 if I want a drain that more accurately represents my average loss. No idea about doze not working on your firmware, I don't even know what firmware you are referring to lol. Force stop is ineffective because most of the time, the apps that want to restart will restart again anyways. Device maintenance is also useless and I use if for nothing else besides a way of measuring my power usage (and frankly it does that pretty crap compared to BBS, GSAM, it just looks pretty cos it matches theme so i keep it haha) . If you are rooted, try greenify (also works on non-root, but I found it a bit less effective) and/or force doze (also non-root support, but I've never tried without root). These may help. And again, like I've mentioned above, look for a possible culprit.

Hope that helps and clears things up guys. Hope I'm not being too basic or condescending, I just reckon ensuring understanding is important. Any questions, fire away, I'm pretty bored these days lol, finishing the chillest year of degree ever.

Source: I lose 1-3% (but usually 1-2%) overnight (6-8hrs) with android wear/BT, LTE, Location all on. WIFI off (I have plenty of data) and NFC off (don't trust people bumping in to me, probably irrational, I heard NFC is off when phone is locked anyways haha)
[Samsung Galaxy S7 Edge Real Life Review] bodomfan:
I'm not rooted so which app would be best to use to check for battery drain
[Samsung Galaxy S7 Edge Real Life Review] waterdaan:
Better battery stats

Give permissions via adb
[Samsung Galaxy S7 Edge Real Life Review] bodomfan:
Is that on computer?
[Samsung Galaxy S7 Edge Real Life Review] waterdaan:
Yes, you need to install adb, connect the phone via USB and then you can give the necessary permissions which you can find in the better battery stats thread.

Guides for installing and using adb are also on xda

[Samsung Galaxy S7 Edge Real Life Review] Extreemator:
Battery is new. I have around 1.3% or worse drain on ALL roms i used. Airplane mode is always on, it's not used for calls or any of that useless things lul. But i get this mob signal radio drain if to trust it. How.........
[Samsung Galaxy S7 Edge Real Life Review] RXT00:
I'm on nougat with root and greenify aggressive doze. Drains 4-5% overnight 8hrs.
[Samsung Galaxy S7 Edge Real Life Review] Theking haha:
I am new to this, i use aod and my standby drain is about 1-2% per hour, is this normal? When i am using the phone, my battery drain by 10% in 40 minutes,sometimes in only 30min, is this normal? Last time when i use it it drain 10% in one hour which is longer than my usage drain now. What apps did u disable? Sorry for asking because i am new to all this apps and dont dare to disable apps because i might accidentally disable an important app that system is using.

Thank you.
[Samsung Galaxy S7 Edge Real Life Review] :re:
exactly the same problem. i dont know what to do anymore
[Samsung Galaxy S7 Edge Real Life Review] Theking haha:
Help, deep doze mode 0% ? What to do?
[Samsung Galaxy S7 Edge Real Life Review] :re:
What a coincidence.Sudden battery drain and all the problems a month or less before Samsung releases the S9 and S9+.Great.I always used Android and I loved it but I think I will now move on and do the iSwitch.
[Samsung Galaxy S7 Edge Real Life Review] Theking haha:
Iphone is the same mate, if they din slow down the phone the battery life will be crap.
[Samsung Galaxy S7 Edge Real Life Review] :re:
they fixed it in the beta
[Samsung Galaxy S7 Edge Real Life Review] Theking haha:
Ya they let u choose whether if u want throttle or not, not throttling has the chance to cause unexpected shutdown if i remember correctly what they say. Anyway, both android and iphone battery life will decrease as time goes by i guess. From what i have read battery life will decrease because battery start to degrade.

Which rom you are using for s7e
[Samsung Galaxy S7 Edge Real Life Review] waingro808:
AOD causes 1% per hour drop in a brand new phone, so yes, that is normal.
[Samsung Galaxy S7 Edge Real Life Review] Xial Xahab:
This does not seem to be normal at all...

Screenshot attached....

Am running oreo for s7 edge leaked...

Have done trying reset etc but no noticeable difference...am rooted and trued greenify and firce doze but no effect... i live in an area wd low signals and the kee varying... is that the thing causing this issue??

Help required
[Samsung Galaxy S7 Edge Real Life Review] dollarpapa:
I can't think of better cause than the leaked oreo rom is eating your battery. Probably not optimized. I'd return to a stock Nougat firmware. I'm on stock (after trying out a few custom roms) with everything on max and after 2 days (imo it takes some time until everything settles in) my phone standby is like 1% /hr with AOD and max resolution only ATT bloatware disabled.

[Samsung Galaxy S7 Edge Real Life Review] jaredalcantro:
I had an issue with the "Pocket" app. This awful crap drained almost 10% of my battery and I did not even used it (I did not setup the app and did not opened it.. not even once..). All good after I uninstalled it.
[Samsung Galaxy S7 Edge Real Life Review] orioldev:
Normal use, how much does the battery lasts?
[Samsung Galaxy S7 Edge Real Life Review] Lord_Byron:
Guys, I have tremendous amount of battery drain on my Exynos 7E. Tried with new battery, it's the same. My NFC is always on regardless of firmware (tried lineage without gapps) it shows semi transparent on, I'm thinking the motherboard may have been shorted. I disabled NFC service to save power (settings show it's not on anymore) but it's all the same. 10% drain every hour, screen off in airplane mode.

Any of you experienced the same problem? Is it the mobo?
[Samsung Galaxy S7 Edge Real Life Review] suljo94:
in nfc does it say on or turning on? I had this with wifi, needed to do fac reset and flash via odin.That was with wifi your problem might be different . try flashing modem(via odin) and boot and formating /data but do a twrp backup first.
[Samsung Galaxy S7 Edge Real Life Review] dawidk750i:

Hey people,

An S7 Edge user for a long time. The phone just had the January Security Update but now the battery is worse than ever. The phone used to last about 1.5 day before the update but now cant even last a day.

Running the stock kernel and that the Kernel (Android OS) is the leading Power Consumer app in GSAM.

Any advices? The phone is not rooted, G935FD model and running the latest update.

Btw, if samsung leaves the S7s with this update, they are saying "f*** the customers, lets force them to buy the new devices". I tried cleaning the cache, updating all the apps, device maintenance... but no result.

[Samsung Galaxy S7 Edge Real Life Review] Alex JC:
Try installing a custom rom!
[Samsung Galaxy S7 Edge Real Life Review] Rob900:
I'm on the same problem, my phone lasts half a day with 3, 3.5 hour of screen (I changed the battery in January). Is annoying, i'm at 8 bootloader version so I can't do anything to solve the problem. I'm really thinking about changing my phone this month, tand for the experiencie, i doubt buying a Samsung phone
[Samsung Galaxy S7 Edge Real Life Review] St0rmAngel:
My S7 edge stock rom 8.0 march security patch,dark theme

Wakelock detector Pro
[Samsung Galaxy S7 Edge Real Life Review] Mischka20:
I already saw that post. But it doesn´t help.

10 minutes standby and I get 2 minutes SSP and 1 minute sensorhub wakelocks. Thats pretty much...
[Samsung Galaxy S7 Edge Real Life Review] skivnit:
Yes don't blame Samsung for installing crappie on ur phone. I lose 0.4%/h with 4g only and Gmail syncing. It's not the phone get over it
[Samsung Galaxy S7 Edge Real Life Review] Sebastiansm:
Well yes, thats too much. In 2 days and 2 hours since I unplugged my phone, I got 48 minutes of sensorhub wakelock and 38 minutes of ssp wakelock.

Seriously. I have the SD820 variant and went to sleep with 21% and woke up 6 hours later with 20%... Doze is working like a charm for me.
[Samsung Galaxy S7 Edge Real Life Review] riyatch:
Is this with AOD on?
[Samsung Galaxy S7 Edge Real Life Review] rytzard:
I had problems with standby drain too. GSam Battery Monitor helped me a lot. Mainly I had problem with WiFi and doze. Ater some research I found out that Viber doesn't allow WiFi to turn off while the screen was off, and doze only activated very few times. I had to change WiFi policy in Viber settings. Also I installed Greenify and turned on 'Agressive Doze'. Before those, I made a factory reset and reinstalled all apps one by one. Before those, my S7E went from 100% to 87-93 in 8 hours, now it only drains 1-2% (AOD off).
[Samsung Galaxy S7 Edge Real Life Review] elpindian:
No, i found that with AOD doze wasn't kicking jn and i would see a 5-15% drain instead
[Samsung Galaxy S7 Edge Real Life Review] mali019:
With everything turned on with the AOD my battery drain overnight is between 0.8%-1%. With AOD turned off its between 0.4%-0.5%. Compared to my S6 the S7 edge has a much better batterylife. I still have between 45-50% battery left at the end of the day when the S6 died in the same period with the same usage pattern
[Samsung Galaxy S7 Edge Real Life Review] Juuls:
Is that per hour drain or per whole night. If it is the last I would love to pick your brain for all phone settings :laugh: My minimum is 2% per 8 hours with data ON and rest off also power save ON and aggressive Doze thru Greenify.
[Samsung Galaxy S7 Edge Real Life Review] mali019:
It's per hour drain. Roughly 1% with AOD and 0.5% without the AOD. I dont turn anything off. Everthing is kept as standart. I'm really happy with the drain so far

Battery drain overnight:

- 3G and Wifi off ( my country doesn't have a LTE) - 2-3%

- 3G on - ~5%

- 3G and Wifi on ~11%

Battery is great if I use it constantly. But if i don't, battery sucks. (two days of continuous use with 4h10p SOT, 3G only, Chicken Invader 4, Skype, Facebook, SBrowser)

I have no idea why
[Samsung Galaxy S7 Edge Real Life Review] ahmoda:
I have a strange problem,

There is something make my mobile stay awake, even when I'm not using for 6 hours? I checked what is eating the battery is showing android system , especially ( stay awake)

I tried to reset the settings , and it worked , 7 hours with 2 % , stay awake in (android system) is almost ZERO ( WIFI:eek:N - 4G:eek:N - Bluetooth:eek:N - Auto Sync: ON - AOD: OFF)

Today I found that the problem is returned back and the mobile can't go sleep and stay awake still is the problem

Now my conclusion is

This problem is happening when I charge the mobile to 100% , after I unplug my cable , the mobile will no go for sleep.

Anybody can help me for this problem

Battery - 90% at 12.30 am. Wake-up at 7 am - battery level 67%. Horrendous drain. AOD off, Edge clock on, Location restricted to Wifi and Cellular and no GPS.

No background downloads or apps running. Android system and display consumed major resources.

Compared to my iPhone 6. this is disastrous. The battery down on iOS was just 1% and at max 2% for the entire night. Yes not per hour but entire night.

Have tweaked some more settings and will do another test run tonight. Its strange that the standby drain is as bad or worse the SoT drain.

drains about 6 to 10% in just 3 hours time while in sleep.

Try switching off Google backup (Settings -> Backup and Reset -> Google Account -> Bakup my data). I was having similar symptoms to you, but since doing this my Android System awake time is down to a few minutes a day not hours on end. I've not rebooted this phone in a week whereas before I was having to reboot almost daily to get rid of this Android System wakelock.
