Samsung Galaxy S25 Battery Health Dropped 4% in Just 40 Days

I purchased my Samsung Galaxy S25 approximately 40 days ago. Since the day I bought the device, its battery health has decreased by 4%, despite the phone having completed only 40 battery cycles.

Experiencing this level of battery health degradation in such a short period and with such a low cycle count has seriously shaken my confidence in the battery quality and durability of the product. I have been monitoring the battery health regularly for approximately two weeks, and I believe this decline is abnormal.

I do not consider this level of battery degradation acceptable for a newly purchased, premium smartphone. Therefore, I request a thorough inspection of my device's battery condition and overall hardware. If necessary, I also request that the device be replaced with a brand-new unit.

I expect Samsung to address my concerns, resolve the inconvenience I have experienced, and provide a clear and satisfactory explanation regarding the battery health deterioration.
