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:
Repair your electronics yourself. iFixit is the repair manual you can edit. We sell tools, parts and upgrades for Apple Mac, iPod, iPhone, iPad, and MacBook as well as game consoles.
