The Oppo F15 is powered by MediaTek’s Helio P70 SoC and it comes only in one 8 GB RAM and 128 GB storage configuration. It’s priced at Rs 19,990 and it will be available in two colour variants including Lightning Black and Unicorn White.

There are several options in this segment where phones from Redmi and Realme have released phones with powerful hardware. While the Redmi K20 is running on the Qualcomm Snapdragon 730, the recently launched Realme X2 (first impressions) uses the slightly upgraded Snapdragon 730G. Hence, the comparison is clear between these three devices. To bring in some more diversity from other manufacturers, we added the Samsung Galaxy M40 and the Vivo Z1Pro in the mix.

When compared to the same RAM and storage configuration, on paper, the Realme X2 offers the best value for money. It goes on to offer more value on the 4 GB variant that goes for Rs 16,999. Whereas for the Oppo F15, it doesn’t really offer anything extra. It will be interesting to test whether the Helio P70 performs better or on par with the Snapdragon 730G on the Realme X2. The quad-camera system on the rear will also be put up for in-depth testing. In our first impressions, it does seem to perform well but we'll reserve our final verdict for later. Stay tuned.
