Now Samsung Galaxy Note is in for a treat with some extra battery power! With a big screen the Galaxy Note will be getting you hooked with browsing and a lot of streaming video. Now the Mugen Power new extended battery will have 4500mAh of power inside. The battery is the HLI-N7000XL.
The stock battery has 2500mAh of power making the Mugen version 80% higher capacity. Naturally, the downside will be a thicker and heavier device than with the normal battery inside. A bit of extra heft is better than the device going dead on you though.
