Mugen Power 4000mAh Extended Battery for Samsung Galaxy Nexus (GT-i9250) with Battery Door

Product Review (submitted on April 13, 2012):

This battery and cover is well made, although I probably could have done without the stand at the back, as it pops down when it's not wanted sometimes.

It's transformed how I use the phone. It's pretty much impossible for me to flatten in a single day.
