vivo Y91i

The vivo Y91i is suited to basic use for people who want a sizeable battery, but its 10 W charging is slower than that of most phones of its time. The 4030 mAh battery has more capacity than most phones launched around then; charging power, however, is worse than most. Overall, the phone is below average among models from its time.

Its IPS LCD display measures 6.2 inches and has a resolution of 720 × 1520 px. At 163.5 g, the phone weighs less than average, and its screen-to-body ratio is above average; its 271 ppi density is below average. The relatively low weight and large screen share are positives, while pixel density is a compromise. The 13 MP rear camera records 1080p video at 30 fps. Its f/2.2 aperture is among the weakest of its time, and the camera overall is worse than most.

The 2 GB of RAM and 16 GB of storage are below most phones of its time. Storage can be expanded with a memory card up to 256 GB. Dual Nano-SIM, a 3.5 mm audio jack and FM radio are included, though connectivity overall is below average. Android 8 runs on a straightforward configuration, and its overall NeoScore is 3.4. This is a basic phone for buyers who value battery capacity and expandable storage and can accept slow charging and limited built-in space.
