Battery drain problems with my Verizon galaxy s7 edge

So I recently bought an s7 edge from Verizon and it has horrible battery life compared to other people with the same phone. I went to Verizon with this issue and all they did was give me another phone in exchange for the previous one but that did not help. Sometimes the battery drops 12 percent on standby overnight. I have found a few apps which have been draining my battery but I unfortunately cannot disable them: gear vr service, help, and knox use over 12 percent of battery each. I wish I could root the phone but no roots are out for the snapdragon version. Help would be greatly appreciated.

Can't you just use disabler pro to disable those apps

Im really amazed how people just go to lets say phone provider and say that they dont like the phone and they get a new one . In Poland I think this kind of thing just wouldnt work. Especially that at the moment this phone is sold out and i was luck to get mine so fast.

I'll try that

Factory reset?
Yea try as mentioned above to disable them otherwise boot in to recovery and factory reset the phone, or perhaps to start out you can try to wipe dalvik and cache in recovery

I don't think using location is what is causing my battery drain because like I stated before my friend also has the same phone but on a different carrier and even with heavy usage his phone battery life is amazing. But I will see which apps do use location a lot.

Yah I saw it before

Do you have AOD on at night? That will burn through some battery.
Those three apps are interesting. How did you determine they're using a lot of battery?
When I look at them in the application manager each one says it's used 17% of battery since the phone was fully charged (24 hours ago). But that can't be accurate. Added together, they'd use more than 50% of my battery capacity, but they don't show up as individual apps in my battery stats, and the largest user (Android System) only used 30%.
Can you post some screen captures of the battery usage screen showing the apps using data? You might also try force charging to 100%, then force closing those apps, and see if there's any impact on battery life. If not, then it might be worth trying Package Disabler Pro. But most Edge owners seem to be getting good battery life, so I don't think that should be necessary.

I am getting the same drain (S7 edge verizon). It only drains my battery at my dorm wifi and when I go home it's fine. I don't think it's a Samsung issue since my LG G3 with a 6500mah battery can't even last two days on standby.

Debating to factory reset due to sub-par battery life after updating to 7.0

I've been debating if I should do a factory reset because since updating to 7.0 the battery life hasn't been as good as it should be. So I'm wondering what the community thinks I should do and getting everything back is a pain in the ass. Battery life hasn't been the best since 6.0 when it was using the february security patch and I can't even go back down to that.
Has anyone had better battery life after factory resetting?

Much better. With a few disabled bloatware and only a few installed app I got 8+ hours SOT, and I have a flat S7 with 3000 mAh battery.

I prefer BK Disabler, the color codes used by PDP for the different types of packages is not as good as the tabbed view used by BK Disabler. At least for me.
Edit: another advantage of BKD is you can disable unnecessary services too.

This probably doesn't make a difference, but is it better to factory reset from recovery than in settings?

I did it from recovery. Somehow I feel uncomfortable to do a factory reset from a running system.
But probably there isn't any difference.

What software version is everyone on my battery life has gone terrible,should I factory reset to improve it ??
Sent from my SM-G935F using Tapatalk 2

I did a factory reset with wiping all cash twice and it didn't help. The battery life stayed as horrible as it was after the update.
Want to mention that i didn't disable any app when using my phone on Android 6.0.1. I had AOT turned on and my battery could handle up to 1.5 - 2 days. Now it's less than a day :/
Also, I wonder, if Samsung reduced the phone's battery life after the Note 7 problems (I've read couple of articles that they were planning to reduce it from 3600mAh to 3000mAh). Does anyone have any correct information about that ?
Thanks.

dalvik cache

Good day people,
Anyone tried the dalvik cache wipe to fix the battery drain in B580 and actually worked?

The. Drain is an app oriented + a setting causing this....

Actually not only me who has the same issue dude it's global with the last update. And the exact same apps and settings were there in B560 and i didn't face any battery issues.

I found that its timely + the usage differs
Check ur apps again
And the best solution to turn of network communication while screen is off

Fixed bluetooth
Probably won't fix it, but hey, it DID fix the glitch I had.
I use bluetooth 100%...phone, streaming...
I'm on 560, and if the phone were turned off/on, and bluetooth was on at the time of
reboot, I had to manually turn the bluetooth back on. After wiping the Dalvik cache,
now, when I power off/reboot the phone, I do not have to manually enable bluetooth.

It could be your physical battery breaking down. Have you seen if any apps are the culprit?

I think this is some massive issue. Many people have the same problem including me. Before the Nougat update my phone battery could live for 2 days, now I have to charge it at least once a day (sometimes twice). Tried to reset the phone couple of times. Nothing helps.

kernel keeping phone awake?

Recently I started experiencing bad battery drain (13% over night) and I noticed my kernel has been keeping my phone awake. I did a factory reset without restoring a back up and still the same thing.
Can anyone take a look at my screen shot and help me figure out a solution?

Try using CPU spy and check if the drain is due to the phone not going deep sleep ?

Yeah it works , try updating to latest firmware as they have improved battery drain , you could turn off AOD , put some apps to sleep in the settings that you don't use and optimize battery usage for them. i was told Mobile Data consumes alot of battery , I'm getting 2% drain for the night unless I leave some downloads.

I am on the latest firmware and I have done everything in the original battery optimization guide by corvo who is now gone. I also have tweaked all my settings for max battery and turned off mobile data. Forgot to mention these issues are with all battery saving tweaks in mind.

I have not. I have literally no idea why the phone is acting this way. I also don't know why my battery stats are not working on the app.
Also idk if this information will help my phone is a snap dragon 855 US variant.
I might try another factory reset. Could you give me a safe to disable list? Perhaps I could try just disabling little pieces at a time and see what happens. Maybe I uninstalled an important service or something.
For example I completely removed wellbeing from my device. Idk if it is important etc or had a role in certain services.

Sure, I have the exynos so that might explain why cpu spy works for me.
Google battery historian (there is a good reddit sub that explains how to use it) which might help identify some issues
