The Sony Xperia line, especially the Compact models, is known for good battery life. My wife and I routinely get 48 hours on a charge on the Z3 Compact and X Compact models and that's without disabling any features such as Bluetooth or GPS, etc.

As for the bloatware, that could be the fault of your carrier rather than Samsung. Android has a "Disable" option in the App Info dialogue that allowed me to disable almost all the pre-installed apps on my phone. Those apps are effectively removed in that they're not running or available in the app drawer. They still exist on disk, but that's a relatively minor burden.
