I've used 40% of my battery, with 15 apps open. But, the screen doesn't show any of those apps. I mean, Android OS isn't even there!
This weird lack of battery usage happens every once in a while, but I don't know exactly what causes it. Usually, it's has a dozen or so entries. Any ideas?

Hello.
Sometimes my phone works normally about 25hours, sometimes it works twice shorter ~10 hours. I've analyzed battery usage and found out that only difference in Android OS process.
25 hours battery usage
Display - 60%
...
Android OS - 4%
10 hours battery usage
Android OS - 60%
Display - 15%
This definitely looks like a bug. OS should not use more than a display.
Is there any way to found out what is Android OS in details?
Why it takes to many power?
P.S. I guess that bug is triggered by programs like Google maps,
but can't definitely confirm it.
Is there a way to shut off maps till needed?
Get spare parts and you can check what is using what. It could also be useful to get watchdog or similar app to check if you have any apps gone crazy. It isn't unusual though that the screen usage is lower if you just haven't actually used the phone that much as the percentage is always 100% and is divided among the things that used the battery, thus the usage percent doesn't imply mA usage.
Sent from my Desire HD using XDA App
I have still pretty high "Android OS".
Display 31%
Android OS 21%
I've tryed Spare parts (Battery history), but it doesn't help.
It just doesn't display such name.
Is there any other way to find out whois is lurking
behind this mysterious title?
I'm betting you have a "suspend process" issue.
What does Battery history from spare parts say? Choose CPU usage, Since last unplugged. Is "suspend" close to the top? What CPU usage details does it have (if you select it)? Obviously look at this data at the end of your phone's battery life, before you plug in.
Also what rom are you using? With cm7 it seems that the battery stats are quite crazy and don't seem to add up to the actual usage, it's been discussed a bit in the nightly thread. The inaccurate stats don't explain the changes in actual battery drain though...
just to be sure, you have usb debugging enabled right?
I'm on official ROM (no root) with USB debugging enabled (I confirm init issue).
My last guess that "Android os" caused by "Location -> Wireless networks".
Now have ~2 days uptime without ever running "Google Maps" and with "Location -> Wireless networks" constantly unchecked.
P.S. Spare parts constantly eats about ~3% CPU at top. Too many for battery monitor. Removed it.

Hey, since you're worried about slight additional CPU-usage and overall performance, you really should consider S-OFFing and getting a different Radio and a custom ROM like ARHD. Or at the very least flash a new kernel, Buzz' kernel did wonders for me.
Ok, I have a problem. Something, and I have no idea what, is launching Gallery periodically. About five or six times I've noticed my battery being very low, and when I check the battery stats, Gallery will have used 50% or more of the battery. When I look at the stats, it might show it's been open for 8 hours or longer (I don't remember the exact breakdown of wake time, etc.) and I restarted my phone last night, so it's gone.
Last night, I finally got fed up and disabled the gallery app, but that means I lose the gallery app for those times I actually wanted to use it (versus when it's getting launched by a program, or maybe I inadvertently launch it and then launch something else and Gallery is sitting in the background chewing up battery).
Before disabling it, I tried installing advanced task killer, and I could never get it to kill any apps automatically, which included it not killing Gallery. I tried both safe and aggressive (or whatever the next setting is) and tried setting the kill frequency to screen off and every 30 minutes (or maybe it was an hour) and it never auto-killed any app.
So, any suggestions on what I can do to re-enable Gallery, but not have it periodically sitting in the background, burning battery like crazy?
I figured that even in standby the Tab S does consume too much battery (5-10% per hour). And a times gets unresponsive and warm. Seamingly there are some processes producing background load. Probably media indexing, syncing, etc. Probably WhatsApp, Facebook, google+
I would like to check, which processes/apps are responsible and in case change configuration or deinstall.
So which is the best tool to track suspicious processes/apps?
Or is there a list of apps that are known to be resource hogs?
I got the impression that the build in monitor (via settings/battery) does not report correctly. I get 60-65% Display, plus 10-20% Android System, all the rest is rather minor. But battery capacity runs down rather quickly even when display is off, so these numbers seem to be not plausible.
Just fresh reboot and youll see touchwiz consumes 2GB of ram
Theres some power consuming background process. Mine idles at 3 hours and will still be the same percentage. I used to have 1.2gig of used RAM on idle time. You may want to install 'quick system info' to monitor app activities
When I go to battery usage, at the bottom only Android System is listed with 100% usage which is impossible. I want to check screen on time but I cant because it won't show Screen in there.
Also, Android System shows a HUGE number like 374738472819486937163 mAg usage.....
Been like this since i got it 2 days ago even when I tried reboots.
I tried 1 more reboot and it fixed itself. Odd....
Since I upgraded to Pie, my battery life is horrible. I go down 10+20% per hour on stand-by. It is about the same as when I've got the screen on. None of the apps I've tried, or the battery settings, show what is causing it. Or, more accurately, they all show different things that don't make any sense. They show apps that I never use, and so I delete them and another one takes its place that wasn't even on the list before. Or they show something like the XDA app, but then show only a couple of wake locks and lots of deep sleep. Any ideas?
