First battery defective? Second a winner

Mi Problema

Wife's battery required too many charges in a day...so time to replace.

Mi Solución

This was my second 3G battery replacement, so had good confidence going in. The new battery, however, did not perform well. IFixIt promptly sent a replacement at NO COST. Second attempt went well and we are good to go! I appreciate the step by step instructions.

Mi Consejo

USE THE INSTRUCTIONS and you pretty much cannot go wrong.
