Audio and Battery
The phone was equipped with a loudspeaker, though it lacked a 3.5mm audio jack – somewhat unconventional for its time. The sound quality measured with noise levels of -88.0dB and crosstalk at -82.3dB, suggesting decent performance for a device in its category. Powering the S5230 Star was a removable Li-Ion 1000 mAh battery, delivering impressive standby times of up to 800 hours and talk times of up to 10 hours, a testament to the energy efficiency of simpler phones.
