Editorial report
LG K31 technical sheet
The LG K31 may suit anyone looking for a compact, light phone, provided a 3,000 mAh battery—among the weakest capacities of its time—is an acceptable trade-off. It weighs 146 g, putting it among the lightest phones of its time, and has a 5.7-inch IPS LCD display. The size is modest, but its 295 ppi is below average and resolution is 720 × 1,520 pixels.
The configuration shown has 2 GB of RAM and 32 GB of storage. Its RAM capacity is among the lowest of its time, while storage is lower than on most phones launched around the same time. Its AnTuTu result is also worse than most. The 13 MP main camera uses a 1/3.1″ sensor, among the smallest of its time, and a 5 MP ultrawide camera offers a wider-angle option. Video recording reaches 1080p at 30 fps.
Connectivity includes LTE, a dual Nano-SIM option, Bluetooth 5.0 and a 3.5 mm audio jack. Android 10 and Google Services are included. Connectivity is worse than on most phones of its time. Overall, the LG K31 is among the weakest phones of its time, with a NeoScore of 3.3. It is a basic, lightweight choice for buyers who prioritize compact dimensions over battery capacity, memory and performance.
