Replacement 3.7V 3500mAh Rechargeable Lithium-ion Battery with Back Cover for Samsung i9100 Galaxy S2 - Black

Pros:　
Very good for its price

Cons:　
Nothing

Pros:　
Love it. When I took it out, I saw that the battery was twice as thick, which is why there is a new back for the phone included. I installed it, and everything worked fine. I plugged it in, and charged it to full capacity, and now my phone goes for two days with fairly heavy usage. Before sometimes the phone would need a mid-day recharge. Now no problem at all. I may be old-fashioned, but phones are getting too thin nowadays. I keep worrying that I'm going to break them. I LIKE that the phone is thicker -- it feels stronger and heavier and more substantial. It is much easier to hold. Vast improvement.

Cons:　
Nothing so far.

Other Thoughts or Suggestions:
Careful if you use a sticky-mount (contact adhesive that allows you to place your phone and then pick it up again without leaving residue on the phone). A couple of times when I grabbed the phone, the back detached and stayed on the stand. Have to remember to wrap your fingers around the edges and hold the back. It doesn't attach quite as tightly as the original cover due to its increased dimensions. Small learning curve, but easy, once you change your mind-set a bit.
