NeoTeo's verdict
Which of the two is the better buy
LG Q92 5G is the most complete choice for performance, connectivity, and a large display; LG Q31 makes more sense when a light, compact phone matters most. LG Q61 sits between them and stands out mainly for its main camera.
Q92 5G pairs 6 GB of RAM with UFS 2.1 storage and 128 GB, versus 3 GB, eMMC 5.1, and 32 GB on Q31 and 4 GB, eMMC 5.1, and 64 GB on Q61. It also has a 6.67-inch display with 2,400 vertical pixels, compared with 5.7 inches and 1,520 pixels on Q31 and 6.53 inches and 2,340 pixels on Q61. 5G, dual SIM support, and stereo speakers add to its practical lead.
LG Q61 is the alternative for camera-focused buyers: it shares Q92 5G’s 48 MP main camera, 1/2-inch sensor, and 8 MP ultrawide. Q92 5G is stronger for rear video, with 4K at 30 fps, and has a 32 MP front camera versus 16 MP on Q61 and 5 MP on Q31. Q61 and Q92 5G both use 4,000 mAh batteries, while Q31 drops to 3,000 mAh; Q31 is lighter at 145 g versus 193 g for Q92 5G.
