I just got my iphone 13pro max 7months before and just woke up to see that my battery percentage health is 99%, is it normal to have 99% battery health only after 7 months of owning it? And how can i get to 100% again without replacing battery?

Battery Health & Performance
Your battery health is fine and is undergoing normal usage. iPhone batteries, like all rechargeable batteries, are consumable components that become less effective as they age. You should change out the battery once your Battery Health reaches below 80% which will take over 2 years to reach under normal usage. Until then enjoy your iPhone.

You cannot return the Battery Health to 100% without replacing the battery.

After 7 months, it would be normal to expect that the Maximum Capacity would be about 93-94%. That is because the capacity drops on average about 1% a month.
If your battery really is at 99%, that is amazingly good performance. Your battery is exceptional, much better than average.
