LG K31 Connectivity and Battery

Connectivity and Battery

The device supports basic connectivity options, including Wi-Fi 802.11 b/g/n, and Bluetooth 5.0, but omits NFC and radio features, which could be a downside for some users. The microUSB 2.0 port is somewhat dated, making charging slower compared to newer models with USB-C. On the positive side, it includes a reliable fingerprint sensor on the back for convenient unlocking and security.

A Li-Ion 3000 mAh non-removable battery powers the phone, providing enough juice for a full day under typical usage scenarios. For moderate users, this capacity ensures that the phone performs adequately without frequent charging needs.
