I suppose, if you typed some more, you should see it stops rendering.

BasicDreams.apk, BasicDreams.odex, BoyueImage.apk, BoyueImage.odex, BoyueLock.apk, BoyueLock.odex, Calculator.odex, Calendar.apk, Calendar.odex, ComicReader.apk, Contacts.odex, DeskClock.odex, DeviceTest.apk, DeviceTest.odex, Dict.apk, Email.apk, Email.odex, Exchange2.apk, Exchange2.odex, Galaxy4.odex, Gallery.odex, Gmail.apk, GmsCore.apk, GoogleContactsSyncAdapter.apk, GoogleLoginService.apk, GoogleServicesFramework.apk, HoloSpiralWallpaper.odex, LiveWallpapers.odex, LiveWallpapersPicker.odex, MagicSmokeWallpapers.odex, Music.apk, Music.odex, MusicFX.odex, NoiseField.odex, NotePad.apk, OSenseUpdate.apk, OSenseUpdate.odex, OfficeReader.apk, OpenWnn.apk, OpenWnn.odex, PhaseBeam.odex, Phone.odex, Phonesky.apk, PhotoTable.odex, PicoTts.odex, PinyinIME.apk, PinyinIME.odex, QuickSearchBox.apk, QuickSearchBox.odex, RKUpdateService.apk, RKUpdateService.odex, SoundRecorder.odex, UserManual.apk, UserManual.odex, VideoEditor.odex, WifiTransfer.apk, WifiTransfer.odex, com.android.vending.apk
and I don't really know how the device works with those app installed.

Later I removed:
AdobeReader.apk, BackupRestoreConfirmation.apk, BackupRestoreConfirmation.odex, Bluetooth.apk, Bluetooth.odex, BoyueBooks.apk, BoyueBooks.odex, Browser.apk, Browser.odex, Cover.apk, FBReader.apk, FileManager.apk, FontManager.apk, FontManager.odex, HTMLViewer.apk, HTMLViewer.odex, Launcher2.apk, Launcher2.odex, SharedStorageBackup.apk, SharedStorageBackup.odex, TelephonyProvider.odex, UserDictionaryProvider.odex, VpnDialogs.apk, VpnDialogs.odex, WAPPushManager.odex, bicp.apk
but I haven't noticed, and wasn't able to measure significant increase in the battery life so they're back.

Better battery life can be noticed after removing:
Settings.apk, Settings.odex
so now settings app is gone.

In top I've limited number of processes with the parameter. There are more processes running.
In dumpsys there are more processes, but for all others there is around 0% usage, so I didn't show those.

Probably I should have mentioned before. Of course those 0% were taken when the device wasn't doing very much. And probably the screen was off. (those 1% in dumpsys when it should be 0% was for sure taken with the screen off).
But a few minutes ago, with the screen on, top was showing that irq/171-rk818 was using 3%. Now, like for all other processes, top is again showing 0% (screen still is on).

Touch on the screen, and your past bangs will be rendered in a burst.

I need the device to work on interactive applications: I need the way and the option to inhibit that it falls asleep.
I don't use the device that way, so I didn't test it, but I think that there are some solutions for your problem. For example you could write an app that uses wake lock. Or easier use Automate (https://play.google.com/store/apps/d...malab.automate) - you can create a graph that keeps wake lock when the bluetooth in on, and releases the lock when bluetooth is off.

Having the same experience: Page turns with bluetooth register but don't always actually turn the page. Sometimes they will turn the page in 3 to 5 seconds, other times not at all until a page turn is made with a touch and then two pages will turn. Or, click the remote three times, not rapidly, and eventually all of them will turn. And the touch is extremely odd. Only the tiniest of touches or using a stylus seem to work some of the time.

The information you posted is excellent, and I will check it thoroughly as soon as I will be at my desk.

I rememered the Wake Lock differently, but it could be it: I will take the Kingsoft (and TextMaker) apk and test injecting the different flags of the wake lock mechanism, maybe starting already with the "full wake lock".

That of Automate is an excellent tip!

But that it is not the only limiter they put: try a VNC (or TeamViewer, or other) session; on other devices, the mouse cursor is updated continuously, on the Icarus it is updated much less frequently. I have not taken stats, but I can say that you have to look for where it "randomly" went at every wrist move - you cannot see any cursor movement.
