A great Tip for my friends. I am a US Cellular Customer and I just recently found they now will exchange your old worn out batter for a new one, FREE of CHARGE!
Here is the message from US Cellular and the link.
Battery Swap, only from U.S. Cellular®, makes it easy to always have a charged phone. Has your battery lost its charge? Just stop into any
U.S. Cellular retail store and swap out your dead battery for a fully charged one for FREE. It’s that easy.
Battery Swap is available on most handsets, Click the link below to find out if your phone is eligible.
