where the android system and os are among the highest on the battery usage
That's my sd820 equipped s7
The Galaxy 7 battery screen shows the same kind of percentages. Two thoughts:
1. Remember that the total of these percentages must add up to 100%. The less you use your phone for other things, the greater the percentage that's going to show up in Android, since it's always running. Put your phone in a desk drawer and let it sit for 3 or 4 days doing nothing, and System and OS are likely to total somewhere near 80%.
2. Marshmallow seems to lump any battery use not directly attributable to an app or the screen to Android System. My Galaxy is currently showing 30% of battery to system, and another 15% to the OS. That sounds like a lot, but I'm at 20 hours on battery with 3 hours SOT and 45% of battery left. With battery life like that, I don't really care where Android is allocating usage.
So don't worry about the percentage going to System and OS. See how the battery actually lasts in normal use after a few days.
G4 on mm shows android is system at 9% while s7 shows 40% at times

Guys can anyone help me with battery life? I'm running cm7 nightly 9 and I've wiped battery stats. Also reduced friendcaster polling to 1hr after seeing the betterbatterystats screen

Everything looks normal to me, and the wakelock didn't show any program that's drainging the battery bad...The Wifi didn't use that much battery too according to your pic. Display didn't use that much also(17%). So I say it might be your weak 3G/GSM signal that's draining the battery.
Thanks man! anyone else?
I was doing some browsing and downloading for a good 2hours or so before leaving it at 30% for about 8 hours with wifi turned on. Woke up to 3% battery
If that's a 2h period you have a display-on time for those 17%, and the rest of the drain is due to a severe case of the Android OS bug. 25% drain over 8 hours idle is horrible. Sadly, no real solution to it other than just trying around wiping the phone and playing with the configurations. **** percentages in the battery screen and look at actual uptime of the different things.
Just curious, do the blue bars beneath the graph correlate with the time axis above it?
Would I be right in thinking that my battery life plummeted as soon as I turned off wifi?

Yes. Probably more likely to be related to screen on, and possibly mobile data. Depending on the brightness, it seems like 4-6 hours of screen on will eat the battery.
Yes it does correlate.
The thing is you just had WiFi on for some period, but you didn't do much in that specific time, it was just on. But just after you had turned it off some apps or processes kept running and you also used the device.
That graph looks pretty fine to me.
Regards.

That's not true screen by itself will not eat battery so fast , review site did media playback test of SD material and battery lasted little over 9 hours.
Only combination of radio+CPU+display will get you 4 hour mark, that's worst case scenario.
Cool, thanks for the replies. Makes sense now
This dont usually happen. In fact, it only happen once.
All this while, the display always use the most battery life, about 50%
followed by android OS, about 10-15%.
my phone was fully charged before i sleep.
but i woke up with 5% battery left, the battery info says android OS used 60%!!
here is screenshot as proof.
i'm really confused, the phone state is appear to be NOT awake,
but the CPU usage is 1000MHz constantly while i sleep.
all this while i've been using rom tool box CPU slider to underclock it to 1000MHz, so thats the maximum my phone can go. i prefer it that way so its much less warm.
any idea whats causing this? as i mention before, this only happen once.
Even so, i'm very curious about this. any one experience this before? or know whats goin on?

Better Battery Stats thread and partial wake locks is your start point .

After a single day of use, my phone was reporting less than 10% remaining, a little strange as I've not used it much, but maybe a run-away app so I plugged it in (Samsung mains charger), then this happened:

Specs: Samsung Galaxy S3 GT-I9300, not locked to any carrier, factory unlocked, no carrier logos or apps. Not rooted, standard OS, Android 4.3, Kernel 3.0.31-2788594, JSS15J.I9300XXUGNJ2.
So I'm now wondering either:
Super-powerful charger,
Phone thought battery was lower than it actually was,
Phone now thinks battery is a lot higher than it actually is,
Battery is on way out,
Something else?
wifi Seems on all the time. remember it's also the one that cause battery to drain.. some user/system apps running in the background..
Thanks, but I was more wondering about how the phone managed to go from 7% battery to 64% battery in less than a minute, and slowly increase from there until I unplugged it. It's at 54% now so appears to be stable.
So far, this phone has the best battery life of any phone I've ever owned. By far. Part of that appears to be incredible standby efficiency, which isn't shown in the standard battery life tests the various blog sites run. I waited for several days to give things a chance to settle in, and on the 5th day charged the phone to 100% before going to bed. Nine hours later, it had used only 5% of battery. No other phone I've owned has come close to that. (Another night, I turned AOD on, and after about 8 1/2 hours battery was down 11%. Not too shabby.)

22 hours, and 5 hours SOT later, I was at 38% battery. I've never gotten close to 5 hrs SOT before. If I got 4 hours, I was down to 10% battery or less. (My eyes ain't great, so I probably turn the screen up brighter than a lot of people do.)
So far I'm pretty impressed with this phone.
