Pro's - Battery held it's charge until I was ready to use it. Con's - It charged my phone SUPER slow (took 4 hours to charge to full) & I only got 1 charge out of it. I tried a different wire, didn't help. This is the same wire I get a quick charge from normally. Unfortunately I threw out the packaging or I would return. This did not happen with my other battery. Going back to that. :(
