iPhone 12 Series Battery Issues
Recently I found that my iPhone 12 mini's battery lift becomes absymal. Then I checked my battery health, which is abnormally low at 90% after less than 9 months usage. So I talked to my friends who also own a iPhone 12 or iPhone 12 mini, finding out I am not the only one. One of my friends' iPhone 12 mini only has 89% battery health. The other two iPhone 12s have 90% and 91% respectlively. All are purchased when the phone came out, which is around 9 and 10 months ago, depending on the model. As I remembered, my iPhone X has 91% battery health after 3 years usage.
I wonder if this is a wide-spreading issue and if I should contact Apple to replace my battery, since 90% on iPhone 12 mini is anot a good experience. Andis it possible that this issue relates to the heat produced by 5G (though I've never used 5G)?
