Is it “normal”? I don’t know. Is it fine, or more than fine? Yes.
Battery integrity, endurance, etc depends on a lot of factors. A few of my own examples:
iPhone X: Made it beyond 1000 cycles before dropping below 80% — by the way, coconutBattery and iOS reported nearly the same percentage.
iPad 2: Reached ~1300 cycles before dropping below 80%.
iPad (6th generation): This one hasn’t faired well in cycles to capacity (i.e., health) percentage, dropping below 80% at ~700 cycles. However, at that point the battery was at least two-and-a-half years old. As of January, coconutBattery reported ~51% battery health with 830 cycles. Is that because the iPad was an Apple refurb? Maybe, but I’m guessing more of a coincidence.
P.S. Remember to occasionally calibrate:
All newly-installed smart batteries should be calibrated as soon as possible. This helps your system get an accurate reading on the battery’s state of charge. W
