I've been monitoring my new iPad 2018 battery health with free Battery Life app from App Store. It shows that battery health has dropped from 100% to 95-96% within few days in very light use after second charge cycle. It does not look normal to me that it deteriorates so fast. Should I have it replaced with new one? Anyone else having the same problem with their new iPad 2018? Please post your results in this thread and/or vote.
