Xiaomi Mi 4s Smartphone Review


High-end phone for a mainstream price. The Mi 4s makes a strong case for spending $300 USD on a new smartphone instead of $600 or $700 for a top-of-the-line model. Find out how the Xiaomi compares to both mainstream and flagship competitors.

high quality display; accurate colors and grayscale ; fast storage performance ; USB Type-C (2.0 speeds) ; thin profile; sleek design ; high capacity battery ; fingerprint reader ; bright backlight ; good camera ; lightweight ; IR remote ; dual SIM

MicroSD slot shared with secondary SIM slot ; slight throttling under extreme stress ; haptic feedback could be stronger ; backlight could be more uniform ; non-removable battery ; very warm under load ; average battery life ; no NFC or MHL ; slippery...

It's hard to find major faults with the Mi 4s. Performance is at the upper echelon of a mainstream smartphone and its design gives an impression that is costlier than its retail price would otherwise suggest. Display quality is excellent and with a...

Xiaomi Mi 4S Review


With the addition of another Mi, Xiaomi has expanded their lineup but does the Mi 4S deliver on its promise like its siblings? Here's our Mi 4S review!

Good design ; Has an IR Blaster ; Great display ; Good performance ; Very good call quality ; Good battery life ; Good camera in ideal conditions ; Great front-facing camera ; Relatively affordable

No U.S. availability ; Lack of U.S. 4G LTE support ; Side-firing speaker sounds distorted ; Disappointing camera in low light ; Ships with outdated version of Android ; MIUI is still missing features found in stock Android ; Bootloader unlocking...

Although the Xiaomi Mi 4S is a great smartphone for the price, its release feels unjustified relative to other products in Xiaomi's own lineup. With remarkably similar Xiaomi smartphones like the only slightly more expensive Mi 5 and the much less...

Xiaomi Mi 4s review: China’s Nexus 5X


The star of the current Xiaomi smartphone lineup is clearly the Mi 5. As this new flagship made headlines at Mobile World Congress 2016, the Chinese manufacturer quietly announced the Xiaomi Mi 4s – a direct competitor to the Nexus 5X. Will this be a...

Good workmanship and high-quality looks ; Solid performance ; Fast and reliable fingerprint sensor ; Good battery life

Slippery, fingerprint magnet back cover ; Average photo quality ; No LTE band 20 (800 MHz)

The Xiaomi Mi 4s is a good and solid smartphone with fantastic battery life. Unfortunately, my overall viewpoint is clouded by an average camera and display, which lacks in brightness.

Xiaomi Mi 4's iPhone-inspired design impresses, as does snappy performance (review)


While the Mi 4's good looks were arguably inspired by Apple, the phone impresses with its own features and capabilities.

The Xiaomi Mi 4 delivers snappy performance, a great camera, and good looks at a low price.

Availability is limited to select markets. The lack of microSD card slot could be a dealbreaker for some.

Xiaomi's Mi 4 offers almost everything you want in a high-end flagship smartphone -- beautiful design and snappy performance at a price that's just too good to pass up.
