NeoTeo's verdict
Which of the two is the better buy
The LG Q70 is the choice for higher performance, a sharper display, and broader connectivity; the LG Q51 suits buyers who prioritize camera and audio. The LG Q61 sits between them: it has the 48 MP main camera, but trails the Q70 in performance and the Q51 in audio.
The Q70 leads performance with a Snapdragon 675 and Geekbench results of 652 and 1,609, versus 233 and 723 for the Q51; the Q61 uses a MediaTek Helio P35. The Q61 and Q70 share 1,080 px horizontal resolution, while the Q51 has 720 px; their densities are 395 ppi, 398 ppi, and 259 ppi, respectively.
For photography, the Q61 has a 48 MP main camera, the Q70 a 32 MP unit, and the Q51 a 13 MP unit, but the Q70 adds 4K video at 30 fps and a 13 MP ultrawide camera. The Q51 brings Android 10 instead of Android 9 and stereo speakers; all three share a 4,000 mAh battery and 15 W charging.
LG Q51
The LG Q51 is the better buy for camera and audio priorities, with stereo speakers and Android 10.
LG Q70
The LG Q70 is the better buy for performance and 4K video, with its Snapdragon 675 and 30 fps recording.
