I had ordered a battery replacement for my Iphone 11 pro max. I bought the second most expensive one, not sure what the exact name is called. I had a professional switch my old battery to the new one, however a few days later after my phone fell from my hands the phone turned off and wouldnt turn on. The issue was definetly with the battery because later i switched it back to my original battery and my phone is working fine, just less battery health. Overall disappointment with this purchase because i had heared great reviews and was excited to purchase more parts for my macbook pro as well.
