iPhone Battery Usage History

So my iPhone 14 Pro Max has suddenly wiped out its battery usage history. I can only see a ‘Last 2 Days’ tab and previously it was the normal ‘Last 10 Days’. Does anyone know the reason for this? I haven’t reset my phone, restored or done anything to it. It is pertinent to note though that I bought my phone this January 2023 and I have a very normal usage pattern where I do everything to follow a ‘healthy’ charging cycle for the phone by using the original wire, original adapter and trying my best not to use any car chargers etc.


In less than a year however, my battery health has fallen 10% and is at 90% as of now. This information is probably irrelevant to my issue but it’s the only thing that might have some correlation maybe?

A1. Restore this from a backup, and it may show up. It is data, so, it might catch up to itself, and appear a little different.


Corellation:

Q2, "In less than a year however, my battery health has fallen 10% and is at 90% as of now. This information is probably irrelevant to my issue but it’s the only thing that might have some correlation maybe?"

A2. Unfortunately, there is no way to determine why, nor when, the Battery Health decreased. In fact, it can even increate at times. It is all just a guestimation on Apple's part. As for the creation, its probably the degrading of the battery,
