    This is something I've been doing with all my devices since Marshmallow was released, and because that I had already forgotten that it was like that until today. For some strange reason or maybe a possible Marshmallow bug, there was news that people were having bigger battery drain with Wifi on than off, before that it was commonly known that having Wifi on all the time was better for the battery than having to use LTE all day. Immediately after I got Marshmallow in the device at had at the moment I also noticed that it was also true for me, Wifi was causing issues and a lot more battery drain than usual.

    Fast Forward months and about 4 devices later and since that time I haven't turn Wifi On except for when it's Charging (I'm using MacroDroid for that without my intervention) and my battery has been basically better than most, if I may say it, when I compare to other users of the S7 edge, S7, HTC 10 and Axon 7.

    Today I remembered this, and I decided to do a test for the first time on my Axon 7, that for the past 2 weeks since I got it, has been nothing less than exceptional in battery life, and I left Wifi on since I unplugged it at 5:00am, now it's 1:20pm and with just 55 minutes of SOT I'm at 84%, not bad for many but poor for me, with Wifi off, like I've been always averaging 8-9 hours of SOT (4 hours of SOT when I go to sleep and at or around 50%) and with the same SOT as of today I've always been at this time at around 90%. So what I'm saying is that even when it's still good battery life, today with Wifi on I'm averaging between 5.5-6 hours of SOT, when I normally can get about 8 with Wifi off.

    So for those of you that can give it a try or have unlimited data and really doesn't matter having Wifi on or off, you can try for one or various day with WIFI off to see if it also helps you. I know it's has been simply great for me, if more people confirms this then it's obvious something is still wrong with WIFI settings in general on Marshmallow and it's not just a Samsung thing.
    That's a good idea for those that also have a really good signal. I routinely get 1 or 2 bars and on occasion it'll say 3G not 4G so that works for some but not all.

    I received my phone on the 18th and had random issues with Android system killing the battery so I took the plunge and did FDR 2 days ago. Seemed to work quite well. Then this morning Android system reared its ugly head again. Fortunately I caught it, was able to see that beaming service was the culprit, disabled it, and the rest of the day haven't had an issue.

    So I'd like to believe the hours I spent with the FDR were worth it but now I'm not sure. I'm glad I did it just to know I started fresh but it certainly didn't prevent things from going sideways again. Maybe the chances of it happening have been reduced though.
    Beaming service?

    Not looking good for me so far. 54% left and I've only had 5 hrs on battery and 1h40 of SOT even though I've turned off all location services...pretty sad...

    SOT is very subjective based on use. You are tracking to make it to 10 hours overall and 3.5 SOT...not really terrible but that is just me...that's a normal day for me if I don't charge it for an extra 20-30 minutes to get another 3-4 hours out of it

    Well at least I'm glad to know I'm not the only with a smaller result. But I see so many people with amazing results here that I would have loved to get 14-15 hours and 5 hours SOT. That would guarantee me a full day with no charge. That's my ultimate dream!!

    Let's make a summary here.

    Tell us, have you disabled Bloatware, all or just a few? You mentioned Location will be off, but did you disable Wifi and Bluetooth Scanning and Google Location service on location? What are your brightness settings? How good is your signal? Have you activated and change to Always the App Power Saving features in Battery-App power Savings-Detail? I think you mentioned that you have a dual sim device,do you have both activated at the same time? If so, have you tried using just one at a time to see if one of them is causing the issue? Can you post today's Battery stats screenshots, as much details as possible?

    All the above questions are very important to know trying to find what may be causing your issue, if everything above is as expected or you have already worked on it, then you must have a rogue app, trying to see your battery stats can help.

    I'm not currently using my S7 edge, I'm using my ZTE Axon 7 and it's different on that option, and I don't have a Note 7, but as far as I know, the Note 7 had those same options that began with the S6, S7 and Note 5. I just checked 3 of my co-workers, 1 with a Note 5 other with the S7 and the other with a S6 edge and all of them, had the same option in the same place. Settings-Battery and at the middle you will see a "Detail" button and it belongs to the App power Savings feature.

    That's a totally different menu and setting so now I'm not sure why I was told that all the Battery settings were the same. So what about that App Power monitor option? It sounds similar to what I'm used to with my previous S6 edge and Note 5 and actual S7 edge, have you tried that to see the options it gives and what it does?

    If you go to Battery usage at the top, does it has more options in the menu at the top right?

    For the app power monitor, you just select the apps you want to put to sleep until you use them..

    Well, then it's kind of similar, maybe that's why you can't see the one I'm saying, maybe it was replaced by this new one. But seeing that it's similar I'd activate and use that.

    Ok I'll give as much details as possible.

    1. I used package disabler pro to disable all the bloatware. This means according to them around 95 packages. Noticed an increase in speed but not in battery.

    2. I turned off all of the location services you mentioned above yesterday. Hasn't had any positive influence so far either.

    3. My signal is pretty great throughout most of the day. Maybe sometimes I drive by somewhere with less signal but it should last more than 5 minutes...
    Yes Im using the dual sim version, but I can't turn off one sim because I need both for work every day.

    4. Luminosity is set to auto.

    5. I haven't turned on any power saving mode cause I want to use my phone as fully as possible since other people manage to do it and have good battery.

    6. Turned off all the automatic scanning options like you said!

    Today, my results are very consistent with every other day.

    Around 10 hours on battery and always less than 4 hours of SOT. It's so disappointing. I would love to hit at least 5 hours SOT. Many people here get over 6.
    The last option I can think about is to reset my phone to factory and not use smart switch, but I've read mixed reviews about this. Below screenshot of my battery stats today!

    Any ideas what I can do now? Thanks again for caring about my issues!!

    It's only 530pm and my phone just turned off. NOT OK WITH ME!!
    I didn't even have location on, neither did I turn on my Bluetooth, which I will eventually need to use when I'm back home to connect my phone to my car.
    Can't believe I have to charge my phone so soon in the day. Now I'm wondering if it's normal than I can't even reach 4hrs SOT, or if I'm suffering from some kind of battery drainage that I need to identify.

    I dont know if its been mentioned or if you can but if I were you Id exchange it immediately. Ive been off the charger for 10 hours and Im at 72% with 2 hours screen on time...

    Ok side note. 2 days in a row my phone erases all my battery usage stats like screen on time and just shows android usage.


    Edit: nm, rebooted and theyre back

    About your brightness, it's in Auto but what percentage?

    Besides what I've told you and you've already done, brightness may affect, you should leave it in auto but not recommended in auto plus full brightness because that's the combo that triggers the most nits (over 1040) on the phone and that's Battery killer by itself. I'm used to not having brightness too high but with Auto I'd say to leave it at about 50%, it will be more than enough to basically all situations.

    Last resort, clear apps cache in Systems - Storage and wipe cache partition in Recovery mode before a full system restore, preferably in Recovery mode also.

    So this is the FIRST time I've been able to go two days without charging! Granted,these past two days haven't been the most heavy usage, just normal usage, but it includes streaming two 45 minute Late Show with Stephen Colbert episodes while driving home from work (mobile signal).

    I really like the Doze in Marshmallow. Except for my 3rd party alarm clock app that hasn't gone off the past two days... I think I've got the battery optimizing for the app off now, so hopefully no more being late for work!
