Both Redmi K40 Pro and Vivo iQOO 7 come with a great design. They feature a non-invasive camera module, a high screen-to-body ratio, and a punch-hole display with narrow bezels. But the BMW edition of the iQOO 7 is simply outstanding. The BMW Edition features a unique design including a stripe with the colors of the brand. The Vivo iQOO 7 has a more compact body than the Redmi K40 Pro, but the latter is thinner and lighter, despite featuring a bigger battery. Further, with the K40 Pro, you get the IP53 certification which proves that the phone is splash resistant and dust resistant.


The displays of the Redmi K40 Pro and the Vivo iQOO 7 have similar specifications. We are talking about two AMOLED panels with a Full HD+ resolution, a 120 Hz refresh rate, and the HDR10+ certification, as well as a high brightness. In both cases, we are talking about high-end displays, but not flagship-class panels. The phones feature an in-display fingerprint reader. Besides its good display, the K40 Pro features stereo speakers, while Vivo iQOO 7 does not.

Specs & Software

Vivo iQOO 7 and Redmi K40 Pro are equipped with the best processor you can get in 2021: the Snapdragon 888 mobile platform by Qualcomm. On the Redmi K40 Pro, it is paired with up to 8 GB of RAM and up to 256 GB of internal storage (UFS 3.1), while the Vivo iQOO 7 has up to 12 GB of RAM and up to 256 GB of UFS 3.1 storage. If we only consider the hardware, the Vivo iQOO 7 wins in its higher-end configuration. The handsets run Android 11 with a highly-customized user interface.



On the camera side, the Vivo iQOO 7 is superior. It packs a triple camera including a 48 MP main sensor with OIS, a 13 MP telephoto sensor with 2x optical zoom, and a 13 MP ultrawide camera. With the Redmi K40 Pro, you do not get a telephoto sensor, neither OIS. That is why the iQOO 7 is able to provide a better photo quality. But the Redmi K40 Pro and its 64 MP triple camera have an interesting advantage: they can record videos in 8K resolution.


The Redmi K40 Pro surely offers a longer battery life in all of the scenarios simply because it features a bigger 4520 mAh battery. The Vivo iQOO 7 has just 4000 mAh, but as mentioned in the intro, it supports the fastest charging technology in the market: with a power of 120W, the phone is able to charge from 0 to 100 percent in just 15 minutes! Do you prefer having a bigger battery or faster charging?


The base variants of the Redmi K40 Pro and iQOO 7 are priced at about €480/$580 in China. We are unable to pick a definitive winner for this comparison because it depends on your actual needs. I would personally choose the Vivo iQOO 7 due to its 120W fast charging technology and better cameras: it is a more innovative phone and I believe it offers a higher value for money, especially because of its cameras. On the other hand, the Redmi K40 Pro offers a more satisfying battery life, stereo speakers, and the IP53 certification which makes it splash and dust resistant. In each case, you will get a perfect flagship for gaming and advanced usage patterns.
