Unfortunately, I couldn't figure out how to give a lower rating. Avoid this product and the seller CellStar. As most are finding, this product works for about the first 3 - 6 months and then dies. After 7 months my phone would die at 50% charge. Plugging it back in showed it starting to re-charge at 0% and in about 15 minutes it's at 65% and in another 15 - 30 minutes at 100%. Phone would work only for about an hour then before dying again - whole procedure repeat - over and over. Another thing that you can find no where in the description or information is that the warranty is 30 days. By time you have the problem it is out of warranty and contacting the seller - CellStar - they deny any responsibility. Luckily.. Amazon stepped in and made it right... Thank you amazon.An Update: Two days after writing this, I received my new battery - different product, different reseller. When I went to swap the batteries, after removing the protective case, I noticed the back of my phone was not tight. Upon opening the phone, I saw that this "GOLD" battery was swollen. As an RC hobbiest who uses all types and sizes of batteries in R/C planes and helicopters - I know when a battery swells - it's defective - it's dangerous. Continued use can result in spontaneous combustion - FIRE and INJURY. If you own one of these - check it NOW. Dispose of it immediately in a safe manner.

High capacity does not describe it. This battery barely lasts longer than the battery I bought it to replace, which is the original battery in my phone, over three years old at this point. I expected it to last most of the day, instead I'm lucky if it lasts 8 hours.The size tolerances are exact. It barely fits in the battery compartment.

Unimpressive, less longevity than a stock OEM battery, had to replace it within a couple weeks. The first week of use was promising, but after that it was useless.

good product

Working great so far..They look great as well. No complaints so far.

Not happy with it at all. DOES NOT hold a longer charge then a normal battery. Any time it gets bellow 50% phone will randomly shut down and will not work till I plug it in. NOT HAPPY, NOT WORTH THE MONEY

Bought this for my wife's phone, looking for more life. it is has a greater MaH than oen and still preformance is not as good as or not much better at all. I will not buy another one.

Arrived ahead of time, works perfect, thank you...
