[Guide] Removing System Apps to Gain Speed-Battery Life-Free Ram / APP LIST HERE !!!

---

Dear Friends,

Here, u can find the list of apps which can be deleted from system/app of ThiaiZ ROM v1.5.3 ( other roms aswell ). After that process, the phone is still usable as normal,has more ram, better battery life and more faster... No critical side effect regarding to my use... You can try to choose the system apps which are not usable for u and delete them with root explorer... Use at your own risk !!!

The below list is done regarding to my phone use behaviour, so if u find any side effects please let me know to update the list...

Hope all these help...

----------------------------------------------------------------

*** Do a CWM BACKUP First!!!

*** Some apks may give temporary infinite FC just after deleted by root explorer and u cant go back to system since they are already running in the memory; Do this : Just lock the phone and then press power button again but dont unlock ; while u r at lock screen hold the power button untill power menu comes and choose close phone to close and restart manually...

*** Deleting some apps which are used as services give u more free ram and free system space...

*** U may get some temporary FC if u enter the settings menu of the deleted app and this is normal...

------------------------------------------------------------------

The /system/app List :

KEEP : System app and shouldnt be deleted.
DELETABLE: app can be deleted regarding to ur phone use behaviour - Some side effects may occur - decide urself whether to delete or not...

Dear nic85,

After a fresh flash of ThiaiZ v1.5.3 and removing the apps mentioned above gives me around 300 mb free RAM after boot and phone is really more faster since many services is not running now like fonts,OTA etc... Of course Free RAM is getting lower after installing some of my apps like beautiful widgets,twitcaster,friendcaster etc but RAM is much more than before...

Kind Regards,

Well done Protochip.

300 Mb Free !!! Wow! That's a massive amount of RAM :) I'll try this. Thanks. This is a must have step.

I still have around 200 mb left..
Using thiaiz rom, V6 supercharger with the 7th setting and nothing really special installed on the phone..
Any advice?

Dear nucleardwarf,

Not with the scripts... After fresh flash of rom and removing all these gives u around 300 mb... With scripts and amany installed apps, i get around 270 mb after close all... whats app, my data manager, messaging is running in the background and some system services... I use go launcher and use its feature to close all running...

P.s. Have u removed all the apps from /system/app/ regarding to my list in the second post?

Kind regards.

Dear nucleardwarf,

It is so weird... Since most of the removed apks are system services which are eating many RAM so absolutely u r supposed to have much more free RAM... i have all three scripts running and mostly i get around 270 mb free ram after close all command... Just stop scripts running and do unsupercharge then check the available memory... i also use startup manager to disable some app running after boot... Many apps is running hidden after boot those we cant see them with standart task manager...


Edit: i have removed scripts and unsupercharge; now i get around 260 mb free ram... Scripts helps some i guess but worse battery life so i dont use scripts...
