TCL 20B Battery and Charging

Battery and Charging

A 4000 mAh non-removable Li-Po battery powers the TCL 20B, which is fairly standard in this segment. The battery life is sufficient for a full day of moderate use, including browsing, social media, and video playback. Charging is facilitated via an 18W wired charger, providing a reasonable charging speed for users in a hurry, though not as fast as higher-end counterparts.
