Kernel and Android System battery consumption

[anon(9263092)]

I just got my new One M8 a few days ago and ran into some battery draining issue.
After charging the device (second charge if to be precise), I went to sleep with 99% battery while all apps are closed, Wi-Fi is turned off and Battery Saver wasn't on.
After 6.5~ hours, the battery was at 89%. In my opinion 10% drain overnight, during standby is a lot and that's why I'm a bit concerned.

Based on some recommendations, I installed GSam Battery Monitor, please see below results.
Do the results seem fine to you? I'm not really sure how to read them.
It looks like Kernel and Android System consumes 36% which is a lot.
Do you have any idea how to decrease the consumption and what causes the Kernel and Android System to consume 36%?

On that matter, it seems like the GSam consumes 5.8%. When I close the app, does it stop monitoring and consuming power or it works in the background and keeps sucking the battery?

Thanks.

Same happened today.
10% drain overnight while all apps are closed, Wi-Fi is off.
That's really strange. Any suggestions, please?

Thanks for replying.
I went over the 'Poor battery life - Kernel os sucking battery' thread and couldn't find any solutions for the problem, that's why I opened this thread.
Also, I'd like to know if the GSam results look fine to you because I'm not so sure they're OK.

You just got the phone yesterday and you are already complaining about the battery life? How about you use it for a week and see if you get 5-6 hours of on screen time. If you get that your battery is fine. You haven't even giving it enough time to settle in.

Actually I do get a fair number of hours of on screen time but I'm trying to understand what makes the 10% battery drain in standby.
Putting that aside, it is the best device I have ever had, it's amazing.

That's because there are no solutions yet. Hence why there is already a thread about trying to fix it.

Those gsam results are very similar to mine. The System and Kernel using the most battery.

OP, I don't see any issues. How is everything going? Any improvements?

Let us know how everything is going. Since you just got the device, you are probably still setting things up and that's consuming more battery than normal. That doesn't explain your overnight usage, but that's not too much drain in my opinion.

Aside from that, how is the device running?
