One of the biggest favours that Samsung have done for us modders is to build a phone and have a battery that can handle not just the Android stuff but also all the Samsung bloatware. This is because that when that bloatware is removed, as in DjeMBeY's Modified Rom's
, there is a lot of battery to be had.

Also, by removing some of that bloatware it frees up some space on your phone. All my 86 apps are on Internal memory. See #1.5
