Alternatives to Apple iPhone 4 battery?

After nearly 3 years, my iPhone battery has started to show it's age. I consulted a few sources, including answers here, bought a kit on Ebay (same kit is being sold everywhere for as low as $6.99), replaced the battery (10 minutes at most), and it dies even faster than my old original one… I called Apple, they offered to install a new Apple battery for only $80 (!), which seems to be a waste for a 3 year-old phone. They said it would last much longer than the after-market c… P. So before I go and get a new phone and contract - are there any alternatives?

If thats your decision on getting a new phone and contract since your 3 year iphone isn't working like it should be and plus maybe its time for a new phone it has been 3 years literally so you should go to your carrier look around see what phones you like and suits your need
