Sensors and Battery
The suite of sensors in the vivo Xplay7 encompassed the essentials: a front-mounted fingerprint sensor for security, along with an accelerometer, gyro, proximity sensor, and compass for various functionalities. The phone was planned to be backed by a Li-Ion battery, non-removable, with 10W wired charging, which was reasonably efficient at the time of its conception, though lacking the fast-charging innovations seen in more recent devices.
