    That's not true because I have used my phone for a couple hours straight screen on time and the android system was still higher. And also I've seen people with 15+ total hours and 4 hours screen on with lower android system usage. I've used this phone like I've used all the ones before and never has android system consistently been higher than my screen
    I didn't suggest that there is a -1.0000 correlation between screen on time and android system. I suggested that all of the percentages are meaningless when taken alone. The overall usage profile matters, and that includes screen on time, signal strength, scanning settings (which you might want to look at, see if your wifi and/or BT are always scanning), idle, whether or not doze is happening, etc. Given what we can see of your stats (which is only %, the next screen is more important where it shows what was going on while various states of drain were occurring), your stats look perfectly reasonable. We can't pick any two stats and say, "this is higher and this is lower". You have to look at the entire context, which (again from what we can see) looks completely normal.

    motivr's screenshot is a good example. 9 hours of what is basically straight idle. Nothing happened, from what we can see, except idling. But only 83% or so (estimated) of the total 33% that's been used (estimated) is accounted for, so there's still about 1/6 of the battery that's been used thus far accounted for somewhere else.

    There is no set value that the OS should be using. It is relative to the other usage of the device. If you use your screen a lot more, then the OS usage as a % of total will be lower. If you're one who idles a lot and has a lower screen time, then OS will be higher as a % of total. Jason Stroud1's screenshots are perfectly normal because the phone is idling a lot of the time and the screen is barely being used. Mrrikki's screenshot is perfectly normal because the screen is being used over twice as much. Signal strength, type of connection (WiFi, LTE, HSPA, etc), screen on time, GPS activity, wake activity, etc. all have huge impacts on battery life.
    Go look a mrrikki's screen shots earlier in the thread. Over 12 hours and around 2 and a half hours screen on time and his android system usage is only around 5 %

    And it is a different device in a different location, with different towers, different apps installed and being used for differing volumes of time and has different settings. And 2.5 hours of SOT is still double the SOT your GSAM stats indicated. I mentioned that it's double in my first post.

    I understand that. But I am very conservative with my battery life as far as keeping battery draining features off and such. I just don't see why other people would have twice the battery life as me. And as far as the 2.5 screen on time from the other post I was using that as an example of the android system percent being low even though most of his time was spent at idle with only 2.5 hours screen on time.

    Nobody should compare their battery life to anyone else's. There are too many variables for that to be accurate. Nor is it fair to compare S7 battery life as reported by the phone to any other device besides the S7.

    So, to really compare battery you would need to have two of the exact same device and use them in exactly the same way to actually be able to tell if an app or something else is misbehaving.

    Signal strength alone makes even very similar usage profiles very hard to compare. I'd agree with you on this. I think we could get two devices to be similar enough to make general comparisons, but definitely not comparisons that would help with troubleshooting.

    Fair enough, just not getting the battery life I had expected. Oh well

    Does Samsung still have the second screen when you tap on the graph that shows details of the graph? That'd help quite a bit. Also, I know you said that you disable battery draining features, but they moved WiFi and BT scanning to location, so just double checking that you disabled those (unless you need them of course).

    I had those disabled already, and when I click the graph is does nothing, so I guess they removed that.

    mumble, grumble. :s That's disappointing.

    I suspect that you have a wakelock somewhere, because your WiFi is on 100% of the time on the GSAM shot and the stats show that the device is active for 3 hr 12 minutes out of 5 hr 47 minutes but the screen was only on for 1 hr 12 minutes. So that two hours could perhaps account for streaming pandora with the screen off, but if that's not the case then that's where I'm suspecting a wakelock.

    Your stats are trending for 3 hours SOT out of 14 hours total usage compared to another user who is trending for 5 hours of SOT over a 24 hour period - so there's definitely room for improvement, we just can't do an apples to apples and say that 5 hours over 24 hours is the goal, because it might be too aggressive or not aggressive enough.

    When I'm asleep it usually loses over 15% last night it dropped for 91 to 74 overnight.

    I think the better question to ask about this is how much CPU time is the system taking up? My android system use is high as well.

    For example - today so far my phone has been on for 5 hours. Screen on time of 55 minutes, battery is at 80%. Android system has used the CPU total for 55 minutes as well.

    The first couple of days, I was seeing near 3 hours by the end of the day of CPU usage by the Android system. What do people with 7 hours screen time get?

    Looks like I am having the same issue with my new S7 Edge on Verizon. I went to bed last nite and the phone was at 76% charge, yes I do have the AOD on but when i woke up it was at 55%. With Doze and AOD supposedly only taking 1% per hour then the phone should have been a lot higher. Today I fully charged to 100% right before 11am and now at a bit more than 3 hours later I am at 85%, that's over 5% an hour drop and according to the prediction I wont even make it until 8am. Android System is using 55% on mine and notice my screen time is low at 8%, my SOT right at the time of this screenshot was only 23 minutes. Something is up with the new Android OS in my opinion. Also my cell signal per is between 60 - 80db during the whole time , My iPhone 6 was able to go two full days with a lot more use than I have been giving my S7E and I I haven't even made many calls with this one, I was on my iPhone all day long.

    This is mine, and has constantly been like this. I have had nothing but issues with this phone, I even had to factory reset my device the day after I got the phone.I even downloaded package disabler pro and disabled bloatware only. It still hasn't made a difference. This is my usage for today, and my phones been in my pocket all morning. I even had power saver on! I really want to like this phone, but I am having a hard time with this battery crap. So after speaking with a rep for AT&T, they suggested going in and exchanging it for another phone since I am within my 14 days. So now I have to spend more money on another screen protector. Such a headache, reminds me of my old iPhone 4 that was glitchy as heck.

    your battery stat is just like mine except mine is S7 flat.
    I noticed that my battery doesn't drain at work as much as when i'm at home.
    I suspect it might have problem with certain Wi-fi router (I have AC2600 TP link router at home. Motorola N router at work). or maybe 4G/3G siginal level.

    My understanding is that AOD does not allow Doze to fire. I have not confirmed that myself though, since I don't want to use AOD.

    The graph shows Doze is coming online and doing what it's supposed to do. I'm not sure if Samsung "weights" the battery indicator, letting it sit at 100% longer than the battery is actually at 100%. If they are that could be artificially inflating numbers from other people that charge to full and then unplug and let it sit overnight.

    I know that iPhone behaves that way so it's not out of the realm of possibility that Samsung is doing the same thing.

    I don't think it's is. It only sits at 100 for a couple minutes for me.

    Mine only drops about 1% an hour over night.

    So I looked in app manager and there were a few apps the had high usage. Knox , settings, gear very, and help all said it used 22% of the battery . They all are rolled into the same service package run in think , they say the exact same thing for battery use and mah usage .
