I've struggled with battery drain since I got my smartphone. I've tried everything. I turned off my notifications, turned off my sync, dimmed my backlight so low I could barely see my screen, I've purchased applications to save battery. none of those things worked. I felt tethered to my charger! on trips my battery would completely die leaving me without a phone! I had enough! I decided to purchase a "bargain" brand extended battery for about 19 dollars. it did not last any longer than my stock battery! I did some searching and then I found Mugen. Mugen extended batteries. These batteries looked different and I decided to try the 3500 mah battery. it came with a replacement back door for my device http://www.mugen-power-batteries.com/?r=450. I read and followed the conditioning instructions for this battery. I was absolutely amazed that the battery stayed at 100% for three full hours at regular use! this was a great sign! well on the first day I managed to have 42% battery left by the time I went to bed at midnight. that's 16 hours of heavy use and still had 42% left of the battery! the battery wasn't even conditioned yet! The next day by bedtime I had 40% battery left at 19 heavy hours of use .The third day I had 50% battery left at 20 hours of use! now I usually can get 23 hours of use out of the battery leaving about 50% by the time I plug in! it's amazing. I can go for two to three days without charging at heavy use ! I am so happy! finally a solution to the battery drain! the battery is quite large and the extra back that's given to you fits perfectly. there are no gaps or mismatched places . I actually like the way it feels in my hand! the design is such that it looks nice and smooth and not pregnant as some would think. it feels solid in my hands and is nicely built! mugen extended battery with back cover is worth every penny! I am finally free! I no longer worry about loosing battery! so if your tired of the battery drain, I highly recommend buying a mugen battery! it is the solution to the smartphone battery drain! you will love your new mugen battery! I know I do!
