Hi.
My battery loses abot 2-3% per hour in idle. Is it some software or hardware problem? Or Tegra 4 specific issue? (No Wi-Fi, apps closed etc)

Try to give it a cold boot.
Often that helps.

Yeah seems to be a common android problem, some apps have runaway processes, others prevent deep sleep and I have also seen kernels lock CPUs. Shame Google can't put some effort into fixing it.

It's not an Android or a Google problem, it's the fault of the developer of the App which is causing this...

Since 4.3 I lose 0 % over night and I can use the table 1 hour every day for reading magazines, e-mail and angry birds for at least 5 days! Just great

Google / Android should not let an app prevent deep sleep imo. Or runaway with resources. But yes you are right some responsibility has to be with the app developer for sloppy programming as well.

In some cases it could be useful or even wanted. Think of an emergency app with running bluetooth and GPS. You would not want Android to kill the app in the middle of your tour

Cold boot didn't help and no draining app seems to be running(. Is a hardware issue possible? Is there a way to check it?
Here's a screeshot from System Panel (results of this night's battery bleed)
P.S. The back of the device seems a bit warm when I touch it...

You can wathc under "settings" -> "energy management" -> "energy table" which app it is and you can prevent it to wake the device up and to keep the device alive.

A few weeks ago I had a similar but stronger akku draining problem with the google apps but its gone (a pitty that I canīt say what it was: me doing this things in the energy management or google updating its app).

My google play-services still wake the device 869 times in 3 days.

New results. Very strange. No power consuming app seems to be running, but I still got -3%/hour.

Battery statistics shows that 80% most power is consumed by the screen. But it the tablet was in sleep all the time, so the screen was off...

Check in Settings on "Energieverbrauchstabelle" (something like "engery consumption table") from Asus, there you can see the power consumption of the apps without Display. If you click on a specific app you can disable it to keep awake or wake tablet from deep sleep...

If that not helps you you should reset everything and go back to stock. Then you can check without installed additional apps if your "bleeding" still is there. Then install one app after another and wait between every single one to check which is the "bad app"...
