iPhone 16 Pro Max battery health dropping rapidly within 3 weeks

Hi everyone,

I bought my iPhone 16 Pro Max (256 GB) on Oct 6, 2025. It was first used in March 2025 with 221 charge cycles and 100% battery health. Now it’s at 228 cycles and already down to 98% within 3 weeks.

My daily screen time is about 3 hours, mostly scrolling reels, no gaming or heavy use. Battery dropped 30% today with light use. I always follow preventive measures — original charger, optimized charging on, low brightness, and charging between 20–85%. Is it normal or something to worry about?!
