I contacted the business inquiring on price for a battery replacement on my iPhone. ******* one of the owners set me up for 1:00 Upon checking in she checked my phone and agreed that the battery needed replacement as it showed 79%I inquired on why if a battery comes at 100% why would it need replacement at just under 80%. Her and ***** explained that the iPhone batteries are just like that, as I expressed it seems closer to 3/4 full and could understand if it was at 25%, but decided they know what theyre talking about so I paid the fee and waited 2 hours for a new batterys to be installed. ******* handed me my phone and had me sign that I had received my phone. Before exiting the building, I checked the battery status which read 79% battery and service needed. Before I could explain my concern ******* proceeded to tell me that its still going to show 79% because Apple is anti repairs and had just changed something preventing it to be shown as updated to the 100%. I expressed I was not satisfied with that answer and wasnt ok with that. They then said the only way to have it register as a new replaced batterys was to factory reset the phone. She took the phone back, told me the phone was last backed up 5 days ago and asked me if that was ok. I told her that it was fine and go ahead to do what they needed to do in order for it to no longer show battery service needed, and it to show battery is at 100%. I waited another half hour and was handed my phone. left the store. Went home to connect to Wi-Fi and get my phone up and running again. After completed the Apple ID update/ download/ reinstall as told to do. I checked the battery and nothing had changed or updated. immediately contacted her at the place of business and she basically stated that they installed a new battery, that thats just the way it is, its isnt like the battery will die in a month, i expressed mydissatisfaction with the service I paid for. She hung up and my calls are not answered
