User level: Level 1 (4 points)Why is my iPhone 17’s battery maximum capacity dropping so quickly? I’ve only had the phone for two months, and it has only 63 battery cycles.

A drop in your iPhone 17 battery capacity after 63 cycles is generally normal, as Apple batteries are designed to lose about 1% for every 50 complete charge cycles and remain above 80% capacity after up to 1,000 cycles.

All batteries age and no two batteries age identically. Charging rates, methods, temperatures and other factors affect the chemical aging at different rates. Batteries are a consumable and don’t last forever. The battery in your device is expected to last 1000 cycles if used and charged under normal conditions.
If you want more specific recommendations please describe in more detail what your battery is doing?

Define "so quickly". What is the Battery Health reading on your phone?
