Why does the battery cover of the Xiaomi 17 Ultra peel and swell after being wiped with alcohol of concentration greater than 75%?
If the battery cover of the Xiaomi 17 Ultra peels and swells after being wiped with alcohol of concentration greater than 75%, please refer to the following explanation:
1. PU leather materials are sensitive to high-concentration alcohol solutions, especially those exceeding 75%.
2. When exposed to strong alcohol, the surface coating can react chemically, which can lead to swelling, discoloration, or peeling.
3. To maintain the appearance and durability of the phone surface, it is recommended to clean the device using a soft cloth with mild cleaning solutions instead of high-concentration alcohol.
4. If noticeable surface damage occurs, please contact the local after-sales service center for further inspection and assistance.
