Battery health in iphone 14
I bought my new phone from currys, in April 2023. It always was at 100% but now (november) that i checked it it has gone to 98%. I have read some other people with similar questions and i cant help but worry that 98 may be too fast before I even close a year with my phone.
One extra question, if i ever need/want to change the battery, do I do this for free and if not, how much would it usually cost?
