Wasn't sure I should buy this since one of the things I like about my cell phone is its slim profile, but my usage dictated this decision. I was tired of not being able to get through an entire day on the overnight charge. I had to charge my phone overnight and again for an hour or two in the middle of the day. Not anymore. Now I can forget to charge it for several nights in a row and the battery indicator doesn't even read low. For me, the extra battery life is well worth the thicker profile.
