Hello, I had the experience of buying two refurbished iPhones, and I was very disappointed with my purchases, in both cases, the battery did not last. Just a few weeks. After extensive research, it turned out that the batteries installed in these iPhones were very cheap and poor quality Chinese batteries.
I no longer have confidence in this type of purchase.
no offense to the ecology, I only buy new, at least we are good for several years and afterwards, it is always possible to replace the battery directly from Apple or Swisscom, and we leave with a battery of origin that will be sustainable.
