Here are lists of system apps you can safely freeze, and an explanation of what each app does. Freezing system apps can help eek a little more performance and battery life out of a stock setup without too much hassle. The first link is a list for an EU Razr, but a lot of the apps are the same for the Bionic. The second link has a list of apps for ICS and JB 4.1 for the RAZR HD. Here is the process I used:
1.) Running rooted pure stock JB in the stock slot of SafeStrap
2.) Made a backup of stock slot
3.) Created Rom-Slot 1
4.) Restored the backup to Rom-Slot 1
5.) Boot Rom-Slot 1
6.) There is no current root exploit for JB, so do your homework before doing anything!
7.) You are now "safe" or should I say "safer" to tinker without losing our precious, precious root
8.) Use Titanium Backup, Rom Toolbox, or the system app manager to freeze or disable what you please
9.) Reboot and profit
I froze the majority of the apps in the two threads and haven't had any issues over the last few days.
HOWEVER, make sure you know what you are freezing before you do it! You could brick if you freeze something vital!
If you screw up:
1.) Boot back into SafeStrap
2.) Wipe Rom-Slot 1
3.) Restore your rooted stock backup to Rom-Slot 1 and try again.
4.) Worst come to worst, use Samuri's House of Bionic to restore
I had to do some trial and error to get it just right.
I also used Better Battery Stats to keep track of partial wake locks and the like to make sure there weren't any rogue processes.
Keep an eye out for any weird behavior or laggy apps.
I can also post the full list of apps I froze, if anyone wants it.
