/system is normally mounted as read-only filesystem.

Remount with "mount -o rw,remount -t yaffs2 /dev/mtdblock0 /system" before editing.

After reboot or "mount -o r,remount -t yaffs2 /dev/mtdblock0 /system" it will be read-only again.

The following APKs I uninstalled without issues. At least I didn't recognize any. Running without that APKs for a few days or maybe a week.

games:

edge.apk, peggle.apk, rollercoaster.apk

social network crap:

Facebook.apk, VZNet.apk

timescape:

Timescape.apk, TimescapePluginManager.apk, TimeScapeProvider.apk, SnsContactImageCacheProvider.apk, uWlopProvider.apk

text to speech:

PicoTts.apk, TtsService.apk

google services:

Gmail.apk, GmailProvider.apk, Talk.apk, Maps.apk, Street.apk, GoogleSearch.apk, EnhancedGoogleSearchProvider.apk

also google stuff?:

GlobalSearch.apk, SearchWidget.apk

maybe self explaining:

EManual.apk, user-support.apk, PcCompanion.apk, Wisepilot.apk, roadsync.apk, playnowclient.apk, TrackId.apk, geotag.apk, VoiceDialer.apk, YouTube.apk, DigitalClockWidget.apk

digital rights management (still have /system/bin/DxDrmServerIpc running):

DrmProvider.apk

replaced with K-9:

Email.apk

runs after first boot after changing SIM:

ReadyToRun.apk

SIM tool kit:

Stk.apk

Someone in this thread recommended uninstalling APKs instead of simply removing them. I second that.

To do so move the APKs from /system/app to /data/app. After reboot you'll be able to uninstall them like with any third party app (Settings->Applications->...).

Some questions I have:

How to get rid of DRM? Simply removing /system/bin/DxDrmServerIpc and related folders under /data and /system?

Is there some information out there about the other pre-installed APKs? Like what they're for?

(74 APKs still left :))

Are some of the following apps known for high energy consumption? I was loosing 31% of battery capacity per 7 hours last night; with 3G and mobile network connection enabled, but with phone in standby. That's not enormous, but had been better some time.

org.connectbot.apk, com.google.zxing.client.android.apk, com.theonion.onn.apk, jqsoft.apps.mysettings.apk, 1org.freecoder.android.cmplayer.v61.apk, jp.co.telemarks.ledlightx10.apk, lysesoft.andftp.apk, lysesoft.andexplorer.apk, com.ichi2.anki.apk, com.fsck.k9.apk, com.wetter.androidclient.apk, com.helixproject.launcher.apk, com.bonfiremedia.android_wikimobile.apk, com.noshufou.android.su.apk, it.medieval.blueftp.apk, com.xelacorp.android.batsnaps.apk, jackpal.androidterm.apk, jp.co.telemarks.taskcontrol.apk, vcard.io.apk, org.kman.WifiManager.apk

Or is there a way to find out, why "Phone idle" is the highest energy consumer or rather which function/module/app is causing it to be?

Thanks,

micha.

P.S.:

I attach my simple APK-moving script. Neat after SE-repair or for handling several APKs at once. Modify it, get it to /sdcard and use it like "sh /sdcard/expose-apps". And don't bother trying to move non-existing APKs, i.e. you can add to your initial list, if you prefer to uninstall the apps in several passes. After reboot that apps are "uninstall-able". When uninstalling, deleting cache and files at first might make a difference. I haven't kept an eye on it. (Calls /system/bin/busybox = requirement)
