Editorial report
Oppo F31 8 GB / 128 GB / India technical sheet
The Oppo F31 suits buyers who want a fluid display, a very large battery and fast charging without carrying an especially heavy phone. Its main trade-off is front-space efficiency: the 84% screen-to-body ratio is worse than most phones of its time.
Its 6.57″ AMOLED display combines 120 Hz, 397 ppi and a peak brightness of 1,400 nits. Overall, the display stands better than most phones launched around the same time. The body weighs 185 g and is 8 mm thick, making both figures better than most phones of its time. IP68 and IP69 protect against water and dust, while MIL-STD-810H covers shocks and drops.
The 7,000 mAh battery and 80W charging are better than those of most phones of its time. Reverse charging, a charger in the box and 1,600 charge cycles add practical flexibility. MediaTek Dimensity 6300, 8 GB of RAM and 128 GB describe this version; the phone is sold from 8 GB / 128 GB to 8 GB / 256 GB. Android 15 has 6 years of update support.
The 50MP rear camera with an f/1.8 aperture and optical image stabilization is typical for its time, and there is no optical zoom. NFC, Bluetooth 5.4, 5G and dual SIM complete the essentials. With a NeoScore of 6.5, the Oppo F31 is best suited to buyers prioritizing its display, battery and protection.
