Battery Maximum Capacity dropping too fast.

Hello!

I have an iPhone 12 which is almost one year old and I know that a Maximum Capacity drop is very normal. A short backstory: I have been taking very good care of my phone since I got it, means that I always put my phone on low power mode, background activity is off and so on. Basically after I immediately got my phone i did everything to preserve my battery as soon as possible. I had my maximum capacity at 100% for a very very long time as i barely needed to charge it (full charging cycle).

Now my problem which is concerning me:

Of course I knew that the 100% are never going to stay forever ,obviously but I didn’t expect the maximum capacity to instantly drop to 98%. As that wasn’t too drastic yet, I didn’t think too much about it but now it’s very very concerning. 2 months ago m maximum capacity showed 96% which was very acceptable and understandable. BUT before yesterday when I checked, it showed 94%, yesterday i instantly jumped to 92% and today it dropped to 91%.

To me it is very weird to see 3% of maximum capacity drop in 2 days, as I know that it mostly depends on the charge cycles. I could never have had so many charging cycles in 2 days to make the percentage drop so fast.

I already contacted Apple Support but even with my guarantee (with is going to end this month) I can’t get a battery replacement (i was thinking because of a maybe defective battery).

My Phone is running the latest version iOS 15.4.1

Maybe you have experienced the same/ a similar issue as I? If yes then I’d be happy to hear about it!
