Protective Cover and Double Capacity Battery for Samsung Galaxy S4 - Non-Retail Packaging - Pink

In all fairness to my review, my stock battery is very old and I can't remember what the charge was like when it was new. With that being said, this product is awesome. I bought a second one for my girlfriend's phone. With my stock battery, I'd listen to Pandora at work and about 4 hours into my day, my battery would need a refresher. With this battery I can make it through my day with a little over 50% to spare.My rating isn't just for the battery it is also for the case that you are forced to use. I absolutely hate cases. I risk phone damage every day because I hate cases so much. There is always something wrong with phone cases, too bulky, buttons don't work right, they fit too right or too loose. This case, on the other hand is done right. Every cutout is next to perfect. The buttons work great with unnoticeable obtrusion. It fits good and feels good in your hand. I would pay more than the asking price just for the case.Now we all know batteries degrade with every charge and tends to be faster with generic batteries. If I notice any degradation of my battery, I'll be sure to update my review.Until then, I've already got my 10 bucks worth. Great product.

I received this just fine and in good order. Sadly in the three months that I have had this battery it has gone from being amazing and holding a wonderful charge, to draining within 9-10 hours if I don't have wireless or mobile data turned off. For a double life battery, it doesn't hold up much better than the battery that came with my S4. I'm now sad that I didn't get a replacement from Samsung.

I got the battery and it for some reason seems worse than the normal one I had the battery goes down so fast

amazing batteries with coverthe mobile works on for 2 days
