Battery life is quickly becoming the most important smartphone specification and now Galaxy S5 owners can buy a new accessory that will give their favorite phone twice the juice. Per SamMobile, the new Mugen Power 5900mAh Extended Battery will double your Galaxy S5’s battery life, although it will also cost you $90 as well.
The extended battery will allow for wireless charging on your Galaxy S5, however Mugen warns us that it won’t have a waterproof casing, which means that you won’t be able to dunk your Galaxy S5 in the water with the Mugen battery installed. The company does say that it’s working on a water resistant battery that will let you get your Galaxy S5 wet just like you can with its standard battery, but SamMobile points out that this battery will not support wireless charging.
All the same, if you’re the sort of person who hates waiting around for your smartphone to charge and you have $90 to throw down, this looks like a pretty sweet option.
