Both Vivo V30 and V40 run on the Snapdragon 7 Gen 3 chip, but users are very much likely to feel far more pronounced boosts in performance on V40. It feels pretty airy while handling multitasking; the switchover of resource-heavy apps is seamless and with no noticeable lags. By the benchmark tests, V40 seems to have better graphics performance compared to its predecessor and hence is expected to be suitable for gamers who fancy playing Genshin Impact and Call of Duty Mobile. It is said to handle such games smoothly even at high settings without heating up.

The display of Vivo V40 is sleek. With its AMOLED technology, colors are really bright, while with the resolution, they look quite realistic. Increased peak brightness from 2800 nits in the V30 to 4500 nits in V40 finally brings much better outdoor visibility. Its curved design is just the cherry on top-the last stroke, which gives it a note of elegance and an immersive effect for the viewer in case of video playback or hardcore gaming sessions.

Regarding the camera, Vivo V40 is where it gets real. It comes with a dual setup on the back, housing two 50MP sensors for versatile photography. The ultra-wide-angle lens offers wide views with less distortion, while the primary sensor fares great in low-light conditions due to OIS. Moreover, there is also a flicker sensor to suppress flickering when snapping under artificial lights.

On the front, it does not disappoint either. High-resolution means each selfie photo will be clear. With Zeiss optics, it gets even better; that is why this phone should make it on the list of best options for users who take quality photos.

The huge 5500mAh easily lasts through a day, even in power-intensive use cases, such as streaming videos and social media browsing, let alone gaming. And once it comes time to finally charge, users will appreciate the ultra-fast charging thanks to the included 80W charger that would get the device fully charged in a little over an hour.

Another area where Vivo V40 nails the design is its modern design language on the back with a glass back and nearly negligible bezels adding more premium feel to the smartphone. The IP68 rating for dust and water protection makes it hard enough to handle daily without any fear of accidental splashes and dust contact.

Some disadvantages do exist, however. Many users complain about the pre-installed applications that are not easy to remove. This may eventually take a greater amount of storage. Though improvements have been made in the performance optimization department, some users might feel a little disappointed with chipset performance since it did not change from its forerunner. Lack of a microSD card slot limits choices for users who need more storage for applications or media files.

Generally speaking, minor flaws exist, but those are not going to take away the good stuff that makes Vivo V40 one of the best smartphones within this price bracket. In other words, powerful performance, display quality, an advanced camera system, and robust battery life make it one of the finest mid-range smartphones up for grabs today.
