With APC8 or lower, the stand-by time is more than double what you obtained. You could get 48-50 hours stand-by with 6h SOT.
[Samsung Galaxy S7 Edge Questions and Answers] overgonas:
Well, I guess it depends on usage. I can't obtain that sot you mentioned on APB4.

I realised enabling wifi is somehow keeping the phone awake. And its a little warm near the top, where the camera module is. I cant determine which apps are causing it to stay awake without root and BBS. Any ideas?
[Samsung Galaxy S7 Edge Questions and Answers] Cholek3:
[MENTION=5473034]Cst79[/MENTION]

Disabling Samsung Payment Framework did not help much. I can get 6h of SOT if I use phone a lot. But something is stopping my phone going doze. When screen is off, I loose ~2% of battery and hour, regardless if it is on WiFi or lte/4G.

You don't need root anymore to get wakelock data. Both wakelock detector light & BBS can give you wakelock stats after you give them appropriate permissions through adb.

For BBS, install the app, start adb, then type in:

adb -d shell pm grant com.asksven.betterbatterystats_xdaedition android.permission.DUMP

adb -d shell pm grant com.asksven.betterbatterystats_xdaedition android.permission.BATTERY_STATS

For Wakelock Detector Light, start adb and type:

adb tcpip 5555

Better way for WLD is to install the WLD Chrome extension in Chrome and give it permanent permissions that can survive reboots.
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
Try Samsung Broswer 4.0, clear chrome and disable it. Try that. And see if any apps have permissions enabled or hiddem sync. Also try downloading the free version or greenify and enable agressive doze. Kind hard to pin point without physically seeing the phone or know what's going on. Maybe screen shot apps? Also, go into developer mode and see what services are running.

I strongly encourage you to, as a test, change your Preferred network type from LTE(preferred)/WCDMA/GSM to WCDMA(preferred)/GSM. It fixed my battery drain. You don't need to keep that setting but it would be interesting to see if it does fix your drain as it did mine.

The

[Samsung Galaxy S7 Edge Questions and Answers] mrnovanova:
I know you said this a while ago but I wanted to say thank you for validating this. I finally know I'm not crazy. Since I changed phones quite often in the last few years I noticed that some phones, like the LG G3 and G4 and especially the iphone 6s displayed bettery information in a completely different way.. With the LG phones I would stay on 100% for at least 30 minutes of light usage. The iphone 6s you sit at 100% for almost 2hrs. I mentioned that on the phones' respective forums but I got flamed. Other phones I've had have a regular depletion of the battery like the oneplus one, nexus 6p, note 4 and 5, s6e and s7e. It seems to me like the same behavior I get from my mazda 3 where I can get 200+KM out of the 1st 1/4 tank to only get 500 KM in total where as if I were to judge by the 1st 1/4 tank I would expect to get 800 KM. I wonder why that kind of practice is even legal. Anyway just wanted to thank you for bringing this up. Loving the battery life on the S7E BTW in spite of the 18%+ battery drain.
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
Something else to keep in mind is that 100% charge indication may not really be 100% charge. See :

http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/

If your battery was really at, say, 97% charge when you took it off the charger, you might actually have lost only 3% in an hour. Still not great, but if there were a bunch of background operations going on not unreasonable.
[Samsung Galaxy S7 Edge Questions and Answers] optimummind:

Yes, that was it. I had the play store edition. Thanks.

However, the second line doesn't work.

I looked up permission for android.BATTERY_STATS and it looks like since Kitkat it was removed. Do you know whether this came back in some other form? Because of this I can only do the first command.
[Samsung Galaxy S7 Edge Questions and Answers] optimummind:
Then just go to the first post and download & install the xdaedition apk. With the xdaedition one, both adb commands work and you'll get full access to all the stats. :good:
[Samsung Galaxy S7 Edge Questions and Answers] antt00:
You have an error in the second line. It should be

android.permission.BATTERY_STATS
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
Got it.. Thanks! That worked.

So to summarize, the correct code to run Better Battery Stats from Playstore without root is:

adb -d shell pm grant com.asksven.betterbatterystats android.permission.DUMP
adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS

According to the battery information page in Settings, something called 10387 is the leading battery drainer on my Verizon Galaxy S7 Edge. This is followed by per-usual operations and apps like Screen, Android System, Snapchat, then Android OS in that order.

What is 10387?

I have a few side-loaded apps like BlackBerry keyboard and Showbox. Could it be adware/malware and how do I fix it?
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Since the last T-Mobile update, I've been generally getting a very good battery drain rate when my screen is turned off. However, every once in a while the rate jumps to the same rate that occurs when I'm using my phone. Each time this happens, Wakelock Dectector Lite shows something called "radio-interface" causing extend kernel wakes. If I restart my phone, the problem goes away and the radio-interface item disappears in Wakelock Detector list. I think this might be caused by some package I have disabled. I'm going to do some testing tomorrow as time allows, but does anyone happen to know what function radio-interface performs?

Guys the last few days I am facing a draining issue of my battery, I have the note 4 910c, the problem is coming from android system, kernel and Google services where they have 35.6% of the draining. Especially android system has 23.3%.What can I do to fix the problem? Why this is happening? I am still waiting for the MM. I have Hungarian CSC.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
You do realize this thread is specifically about the Galaxy S7 Edge, right?

Different hardware could have wildly different behaviors, and since we're already on MM with the GS7E any reasons here for power usage probably won't match what you are experiencing.

I noticed that if I removed the phone from the charger without turning the screen on, I will have some wakelock that won't put my phone to sleep. I recall this with my note 2 years ago. This happened after the latest update I received OTA. This didn't happen before the update.

*update

so after turning off google app data sync...nothing changed really, although the process does not appear Android System is high as usual.

Tried a factory reset from the recovery, wiping cache also.

First cycle of usage, Android System stayed steady at 13%, with 4H of SOT.

Second cycle and Android System is at 61% ! I have the phone unplugged for 1 hour now and already lost 10% and the phone is just sitting there.

This is really hopeless :(
[Samsung Galaxy S7 Edge Questions and Answers] seanie2322:
I also had this problem. id charge my phone fully before going to bed and when i wake up with would be at 85-88%. Android system using 62% everytime and the phone was not going into deep sleep. I downgraded to the previous firmware and it solved the issue. only have around 3% drain overnight now with the phone in deep sleep for 7-8 hours.

Still i believe we should not have to do this to solve an issue samsung need to fix it. Ive tweeted samsung on twitter but no response. It seems to be exynos users suffering the most.
[Samsung Galaxy S7 Edge Questions and Answers] sicutero:

My phone's screen turns on by itself when I remove it from the charger.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
Had you used the phone for anything else? If not then that's why it's so high. That percentage is relative to what uses how much power from what's been used so far. If you didn't use it for anything else then android system is the only one using battery so that number would be higher. If you started using other apps that number would drop.
[Samsung Galaxy S7 Edge Questions and Answers] ref1ux:
I seem to have fixed this by deactivating location history and smart alert. Before the max SOT I could get was 4h 38m, but today I managed 5h 21m with 18% left. So looks like on course for 6hrs, which is what I used to get on my first S7E.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
The Android System drain affects standby time much more than the SOT. How much drain percentage do you have now from the Android System ? If over 10-12%, the problem is not likely to have been fixed.
[Samsung Galaxy S7 Edge Questions and Answers] ref1ux:
It's around 22%, which is still higher than I'd like. But if I can hit 6hrs SOT (which is more than 1h 30m longer than my 6P) that's a decent improvement anyway. Maybe the rest can be fixed with another software update.

There is a Beacon ble wakelock under Google services and I see it sometimes when I use Bluetooth. After searching some more I learnt that this service scans for Bluetooth beacons used in stores to get the location of customers. But I had disabled Bluetooth scanning. I am on tmobile with APD7 update.

Also under android system my major drainer is ims service which could be related to wifi calling
[Samsung Galaxy S7 Edge Questions and Answers] sicutero:
It doesn't really matter if you use the phone or not.

I tried this today, unplugged the phone and checked FB, emails etc, something to occupy the phone with, again Android System spiked at 62%.

I have to restart the phone every time I unplug it from the charger in order Android System to fall at 13%, then also the phone will finally Deep Sleep.

Now during the day Android System will remain very low and never spike above 20%.

Any solution so we dont have to reatart our phones after charging
[Samsung Galaxy S7 Edge Questions and Answers] Jaqen H'ghar 86:
For the majority of people having Android System battery drain (started with April's update), the cause is the *backup* android system wakelock, which is directly related to Google Backup and it prevents the phone from dozing and entering a deep sleep state..

The *backup* wakelock is activated once you plug your device into the charger and it continues to manifest no matter what you do because it's stuck in a buggy loop, only reboot will fix it temporarily until you charge the phone again.

Through many trial and error experimentation I finally found an easier fix than rebooting every day.

1- Reboot the phone (just once to fix the wakelock, or the next steps won't work if it's already activated)

2- Before charging the phone, turn off WI-Fi & Google Backup

3- Fully charge the phone

4- Unplug the phone

5- Turn Wi-Fi & Google Backup on again

6- ???

7- Profit!

The culprit is Google Backup, and the bug is activated once the device is plugged into the charger and on Wi-Fi, but if it's turned off before and during charging with Wi-Fi off it'll not be activated.

But if the wakelock is already activated, it won't go away even if you turned backup off.

The Wi-Fi is a strange case, I once rebooted the phone, turned backup off and charged the phone with Wi-Fi on and I had the wakelock. My guess is even with backup off, some logs will still try to backup when Wi-Fi is on (Wi-Fi passwords maybe)

4th day without the Android System battery drain and both my Nexus 6P and Galaxy S7 Edge doze properly now.

Hope It'll help you as it helped me.

I would give the Gservicefix app a try.

That is, you can uninstall the app after applying the fix.

[Samsung Galaxy S7 Edge Questions and Answers] Idan73:
Don't want to jinks it, but for me the issue with wakelocks that show after charging, is solved by simply disabling google backup, restarting phone and enabling backup again.

Found the post on Internet. No apps, and no repeated clicking of options back and forth. Especially like my wifi on all the time, now that my data package is much less than it used to be.

Tested by repeatedly plugging to charge then reseting cpu spy and checking for deep sleep. Hope it never shows again. This was a stressful month especially having wife's phone without issues while I could feel mine always slightly warm in the pocket.

I suspect I have this Google backup wakelock, although I don't know for sure since I've not been able to get the Wakelock Detector no-root workaround working. A few times I've noticed Android System keeping my S7E (Exynos) awake fresh off a full charge, although last night it happened overnight when the phone wasn't fully charged, not sure if that's the same issue.

Does the Google Backup actually do anything that useful anyway? I suppose it backs up things like wifi passwords and installed apps list, but I can live without those. Any other repercussions to just turning it off permanently?
