While setting out to clean up my ROM install, I was curious how small I could make it. I usually delete a ton of these after install, but that's getting old. So I wanted to see out of the 400 apks that come on the phone, how many could I axe? Between my experience in uninstalling these, and googling around, and realizing that for some reason a huge chunk of these cannot be found via googling... I decided to make to this list.

If you can identify any of the blue ones, or confirm whether some of those with unconfirmed status can safely be axed or not...I'd appreciate it.

Disclaimer
As is always the case, while I am not out to lie to you, I am not responsible for your removal of any of these apps from your phone. If it causes you to need to restore from backup, or re-install a ROM, that is tragic, but your responsibility. If you do find due to an update or another app you install/use you should not have deleted one... please let me know, and I will update this list accordingly.

I have removed just about every single file on this entire list, including all the ones you have in red marked as not safe to delete... and no ill effects on my device at all.

There are also a few htc/sense related files in /system/lib that I have removed, but I can't remember the file names off the top of my head. I'll see if I can figure it out and I'll post which of those I removed as well.

The DFPI.apk stands for Demoflo package installer.
I beleive is there so you can install some sort of demonstration recovery for the phone.
Which I think is obviously useless for us.
I always remove it before flashing.

This is a great post for all to use and try. May I suggest this be Stickied/Pinned as this is could ba a project for just anyone who isn't afraid to reflash a ROM to determine what can and cannot be removed.

:D

I have frozen EPST with Titanium before. I didn't know exactly what it did... but it always seemed to be running, and I could never see any benefit. I was told by Scott not to remove it... and he knows way more than I do.

The other ones in Red are really if you still want sense. You can remove virtually all HTC files if you desense it... but that really isn't the point of this, because there's scripts and tools if you want to de-sense it... this is really about trimming down while still keeping using sense.

Thanks everyone so far, I'm updating these per your posts now.

Trim it is used to make ringtones from the mp3's loaded into the HTC media player.

Nice list though, might be removing some of the extra apks in the de sense util when I get a chance

I also think this should be Pinned. I was looking for the old list of freezable apps we used back when we had temp root to clean out some of the bloat in the current rom. This is exactly what I was looking for. Thanks OP.

Guys,
Have any of you deleted or frozen the majority of these apk's and seen a substantial battery life increase?

Sent from my ADR6425LVW using XDA App

Only freezing or deleteing the ones actually running could gain you battery life. Otherwise they just sit on your phone taking up space. Also, I've never not removed the majority of these since I rooted my Incredible. I've never ran fully stock Rezound (maybe for a few hours the day I got it, lol).

Once I get somewhat farther (I've gotten a list of all the stock ones too I'll add later today) I may start marking some of them as background processes that disabling would free up memory (and theoretically gain battery life).

In the mean time, just check in a process explorer for running ones and if you don't use those and they're safe to delete, go for it.

Is the HTC Sync apk named differently in ICS? I'm on ineffabilis and it's not named HTCSync.apk - it's something different.

I see a few options here:
AccountSyncManager.apk,com.htc.settings.accountsync,Accounts & Sync
com.htc.Sync3DWidget.apk,com.htc.Sync3DWidget,Sync Widget
CSPeopleSyncService.apk,com.htc.cspeoplesync,CSPeopleSyncService
GoogleCalendarSyncAdapter.apk,com.google.android.syncadapters.calendar,Google Calendar Sync
GoogleContactsSyncAdapter.apk,com.google.android.syncadapters.contacts,Google Contacts Sync
HtcBackgroundDataWidget.apk,com.htc.rosiewidgetsbackgrounddata,Auto-sync
WeatherSyncProvider.apk,com.htc.sync.provider.weather,HTC weather sync provider

I have yet to actually walk through this list I got, but it could be one of those.

    Disclaimer
    As is always the case, while I am not out to lie to you, I am not responsible for your removal of any of these apps from your phone. If it causes you to need to restore from backup, or re-install a ROM, that is tragic, but your responsibility. If you do find due to an update or another app you install/use you should not have deleted one... please let me know, and I will update this list accordingly.

    I am attaching screenshots of what I have left in my /system/app folder of the ROM I use. There are .apk's in there that are safe to remove, but I use them, so I left them. There are no issues what so ever when flashing the ROM or setting up.

    I have removed. Although I removed Rosie.apk and HTC_IME.apk, there are two other .apk's that replace those.

    Rosie.apk is replaced by the Go Launcher EX .apk in the /data/app. (as long as you have a third party launcher, and you do not use Rosie, its safe to delete)
    HTC_IME.apk ...this ROM actually has an ICS style keyboard too. grey with red keypresses. I like it because its look BEATS. its called Latin.apk

    as long as you have the .apk you can through them in the /data/app folder and it will install it when you flash the ROM. The filenames cannot have any spaces.

    Hope this helps anyone.

      I'll do a full list of everything I've been deleting since having my Rezound, which includes the above, among many others.

    I have removed just about every single file on this entire list, including all the ones you have in red marked as not safe to delete... and no ill effects on my device at all.

    There are also a few htc/sense related files in /system/lib that I have removed, but I can't remember the file names off the top of my head. I'll see if I can figure it out and I'll post which of those I removed as well.

    I've added a recommendation about removing Smith.apk.

    Updated other files in the list for HTC One ports.
