T-Mobile Sidekick LX Audio and Battery

Audio and Battery

Audio functionalities include a loudspeaker and a standard MP3/WMA audio player, catering to users who enjoyed music on the go. Notably, the phone lacks a 3.5-mm headphone jack, which was not uncommon for the time but could present a limitation for personal audio use. Powering the device is a removable Li-Ion 1540 mAh battery, offering up to 96 hours of standby time and nearly 7 hours of talk time, which was fairly decent under moderate use conditions.
