Battery Life
One of the standout features of the Philips X528 is its exceptional battery life. A removable Li-Ion 1500 mAh battery powers this device, providing users with a remarkable stand-by time of up to 2400 hours and up to 30 hours of talk time. This longevity is particularly appealing to those who prioritize battery life over advanced functionality, making it ideal for environments where charging opportunities are limited.
