    This is my usage right now. I'm at 44% now after 16 hours, with another projected 14 hours to empty. Today was a near normal day of usage -- some texts, a few voice calls, some BBM, some browsing, music, Words with Friends, a few app updates from the Play Store, and seven email accounts. Oh, and I lost a bunch of power when I got the September security update from Big Red.

    I use the typical power-saving tricks like WiFi shutting down as I leave home, location set to just GPS unless I need Maps, display brightness to auto with 30-second timeout, AOD and Edge tools are off, etc. I've disabled most of the bloat by either disabling the app in the Application Manager or with Package Disabler Pro (paid app -- root not required). My BT is always on and connected to my earbud and my Fitbit.

    I thought these 'smart phones' had really poor battery usage, but I have been amazed with my S7 edge. She is running a dual SIM system and I can easily get 3 days on standby and bit of web/email browsing. That said I think the biggest saving to be had is to run the screen at about 50% after 5 minutes I bet you won't notice you've done so either!

    Has anyone reverted back to a previous security patch? Seems like August Security Patch is horrible on battery life.

    blessedred - not likely!, I've found no issues with battery life and literally minutes after that patch arriving my two sims actually started to work, which they hadn't done since I first got the phone 2 month previously - that patch actually saved my sanity

    Oh. For me it's Android System usage is ridiculous and I'm getting like 70% of the battery life that I used to. I think some others in the August post agreed.

    I bought the S7 Edge because of the large battery capacity, but have suddenly suffered a severe battery drain issue so searched high and low for a solution.

    Everywhere you look there are examples of people having issues and endless advice as to how to maximise life, usually in the form of 'turn your excellent smart phone into a very poor dumb one'. However, I have had a thought which I'd like to share.

    Perhaps this apparent fast running, battery draining phone and the variation in peoples' experience has the one root cause and it is nothing other than poor battery manufacture. The capacity should be 3600mAh, but how do we know? How do we know when we buy it and how do we know six months later? We only have the spec to go from. If the battery is of a poor quality it may well be that only a proportion are genuinely the full capacity and many will fail too soon.
    Maybe the Note 7 debacle is just a more obvious consequence!

    Clearly, there is something wrong when you have a battery read out which shows a combined use of about 360mAh and a gauge that indicates 56% left, which is where mine is at now. Mathematically, I've used 10%, or I've only got a maximum capacity of about 650mAh. Hmmm....

    Are so many of these threads that suggest battery saving routines simply missing the point that Samsung (and other companies too) are skimping in the battery?

    1. No, because people have noticed that battery drain problem only after certain updates, with those having the phone before that update seeing the great battery life that was promised, pointing it to a software issue.

    2. Samsung knows people will randomly buy the phone for tests, tear downs and other things. Not all reviewers get the phone free. If they do something of the sort that you mention, they'll gonna be found out easily.

    3. People who suggest battery saving routines are missing the point sometimes. There will be a root cause for sudden change in battery life. Of course, addition of an app that eats a lot of battery will necessitate changing that app's behavior to maintain previous battery life, but it should also be pointed out that the user expecting the phone to maintain optimal battery life when they set up a lot of apps to run in the background is also erroneous.

    Perhaps, in some instances, the updates affect the capacity monitor, but I'm not aware of how that might interact with the operation which I would've thought only depended on available voltage.

    That said, I just have a niggling feeling that for so many people to suffer such a wide variety of issues it seems unlikely to be down to the OS. If it was then you would see a good number of successful solutions.

    Ever took the phone to a corporate carrier. Let them hook it up and see what may be causing the problem.
    They have a lot of equiptment for this kind of testing.

    It's not the capacity monitor, but the power usage itself. A previous update caused a Google Backup battery leak. After the May or June update for example, my battery life dropped to almost half of what I used to reach. Turning off Google back up returned it to previous levels. That points to a simple OS battery bug.

    Currently, since the June to the latest update, I noticed that mobile data and WiFi is eating more battery than they used to, with either of them on causing a battery standby drain of 4% per hour, in contrast to having them off where I go to down to 1% per hour. That's a 4x increase in usage, which simple turning on of the data should cause. I could accept that on a 4G connection in a bad signal area, but the phone on standby with WiFi should not cause that much drain IMO. Since it was working correctly before an update, that again points to a software coding error on battery usage. At this point that is the more likely explanation compared to some conspiracy theory on the manufacturers are paying up the FCC to screw the customers over, especially in this day and age where customer satisfaction is paramount to sucess. It doesn't cut it anymore to just release a good product, like Sony does every year (but they still fall flat despite devices that can arguably be said to be superior to the S7 or HTC 10 in a number if ways). Customer satisfaction and brand loyalty ate big factors, and doing a battery job like you suggest is a bad way to cultivate those.

    I would take the phone to a corporate carrier, and take the charger and cord.
    Let them look at everything.
    You have 2 weeks that you can return the phone.
    I turned everything off that I did not want notifications from.
    Disabled all the apps that I could that I don't want to use.
    I went into Device maintenance and put a lot of apps to sleep.
    And did the battery and ram work in the app.
    My note 7 has been working great.
    How many apps do you have open in your internet app.
    Or in your google app.
    How many pages do you have open if you hit the button on the bottom left ?
    How often do you cut your phone off and back on.

    Wished I could help.

    I have no problems with usage. Even after a restart I see this usage. It's not a big deal when I get 18hrs of usage and over 4hrs screen time. I've been with Android long enough to know that it's just the setup I have. And maybe Facebook. Lol.

    You could well be right and I wasn't sugesting a conspiracy regarding the battery performance, but rather just poor quality overall.

    The aspect that has me puzzled is that there seems to be an almost random presentation of the issue, other than short battery life, and everyone seems fixated on percentage of use in the monitor. The percentage is, to a large extent, meaningless, whereas the power use is the important number. If everyone with a probem totals the power use and divides by 36 the result should match the percentage of battery used. If not, it means either a faulty battery, a faulty guage, or faulty monitor, or am I missing something?

    To go back to the faulty code, again it seems very odd that Samsung would keep introducing badly written code that would cause random items to go into meltdown and none of them show up in the battery monitor. If they did show, most of the threads would be asking why this item was misbehaving, rather than why is battery life short, followed by myriad suggestions as to what to app to turn off, or what setting to reduce.

    You still might be right, but I do think that most of the 'diagnostic' suggestions are wide of the mark and just confuse the issue for people like me who suffer such a problem and come looking for solutions.

    Mine has been using the battery really well since I got it in July, and my displayed power level seems to be accurate. I just checked it for the first time using my advanced math skills (Windows calculator). I have used 1606 mA today. Divided by 3600, that works out to 44% of my battery used. The value on my battery meters, both the native battery indicator and GSam Battery Monitor, both indicate 56%. Looks to be dead on. I have no reason to believe that Samsung built my phone with anything but 3.6A battery.

    I was able to achieve this by turning off the following toggles & activating Power Saving mode only when the screen is turned off: data, and WiFi.

    The screen brightness is set to Auto, location is only turned on when I need it, and sync is always turned on.

    I use Greenify and use its Aggressive Doze & Doze on the Go functions.

    My GS7E is a Sprint 935P flashed with the 935U ROM.

    It looks like your google play was doing an auto update of some apps while you were sleeping. You can disable auto updates from the google play app menu.

    6hrs of SOT with 42% left? What brightness? And what version Snapdragon or Exynos? That sounds much better than what I'm getting. I can max out at 7 1/2hrs of SOT but it sounds like you can get almost 9.

    I was getting bad battery after the september update. Then it fixed itself. Although android system was draining 15% now its draining around 30%. Seems like my battery life is good. Nearly 6 hours and 23 mins on screen time and 17 hours of battery usage. If it doesnt settle down within a week prolly should take it in to get looked at.

    You think if your having battery problems, you could try Greenify Battery app from the app Store ?
    It will put some of the app programs and all to sleep. Giving you better battery life.
    you got something using the power.
    Might be a few apps using power.
    have to gone in and turned notifications for Samsung Pay off >
