Samsung also pulled the removable battery from the Galaxy S6 and Galaxy S6 Edge designs. As you might have guessed, the Galaxy Note 4 design features a removable battery and there are a few reasons why you might love this.
First, it means that you can swap in an extended battery for more juice. The Galaxy Note 4 already features some of the best battery life you can find and you can improve it with a massive extended battery. Just be prepared to spend.
It also will come in handy if something happens to the stock battery. Instead of having to bring it in for repairs, you can order a stock battery (or an extended battery) online and repair the device yourself. That cuts down on time and headaches that often pop up in the shipping/repair process.
