The Xiaomi Smart Electric Shaving Razor S302 is the latest entry in Mijia's growing line of connected grooming tools. It pairs a triple-head rotary cutting system with a Bluetooth-connected app that tracks blade life, motor load, and even shaving routine consistency. On paper it competes with the Philips S5000 series and lower Braun Series 5 models. In practice, the price is roughly half. Here is the long-form review based on owner reports, comparison videos, and Xiaomi's published spec data.
What is the Xiaomi Mijia S302?
Mijia is Xiaomi's smart-home and personal-care sub-brand, which has steadily expanded from air purifiers and rice cookers into electric toothbrushes, hair clippers, and now mid-tier electric shavers. The S302 sits in their second tier, above the entry S100 and below the flagship S700 series. It uses a three-head rotary cutting system rather than the foil design used in Braun shavers, which favours a slightly closer cut on flat planes at the cost of being a little slower on neck stubble.
Spec highlights include a 7,500 RPM motor, magnetic charging via USB-C, IPX7 water resistance for full wet-and-dry use, and Bluetooth pairing to the Mijia app. The app is more than a gimmick: it logs cumulative blade hours and prompts head replacement at the right interval rather than guessing. Check the listing for current battery capacity since Xiaomi has revised it across regional variants.
Design and build quality
The shaver measures around 130mm tall by 65mm wide, with a matte black or grey finish and a small chrome accent at the head joint. It feels denser in the hand than its 200-gram weight suggests, which is a sign of decent internal construction rather than empty plastic shells. The triple head pivots in two axes for face contour following, and a small pop-up trimmer extends from the side for sideburns and moustache lines.
The control layout is minimal: a single power button on the front and a charge indicator above it. There is no separate cleaning button or mode selector, which is a deliberate choice for simplicity. The included travel cap is a friction fit that does the job but is easy to lose. The supplied USB-C cable is not the longest at 65cm, but most users charge it on a bathroom counter, so this is rarely a problem.
Performance and key features
In daily use on light to medium beard density, the S302 produces a clean, comfortable shave in around 2 to 3 minutes. The triple-head rotary design glides well across cheeks and chin, and the floating head handles jawline contours without dragging. Closeness is genuinely good for a rotary at this price, landing close to a Philips S5000 on the first pass and within one pass of a Braun Series 5 over a full cycle.
Wet shaving with foam works well thanks to IPX7 sealing. The shaver runs at the same RPM whether the head is clogged with foam or running dry, which speaks to a well-tuned motor controller. Skin irritation is low for users with fine to medium facial hair; coarse, dense beards may still prefer a foil shaver for the first pass. The pop-up trimmer is sharper than the equivalent feature on competing budget shavers and handles sideburn detailing without tearing.
Battery life and durability
A full charge powers approximately 60 to 70 minutes of cutting time, which works out to roughly three weeks of daily 3-minute shaves between charges. USB-C fast charging delivers a 5-minute quick top-up that yields one full shave when the battery is flat, which is a genuinely useful feature for travel. Charging from empty to full takes around 90 minutes.
Durability is generally good but tracks the typical Xiaomi pattern: the device itself is solid for two to four years, while small accessories like the travel cap and the magnetic dock are slightly more disposable. Replacement cutting heads cost around 20 to 30 USD on AliExpress and are recommended every 12 to 18 months depending on usage. The Mijia app prompts you when replacement is due based on accumulated runtime.
Price and value
The S302 typically lists between 55 and 95 USD on AliExpress depending on bundle and sale season. Compare that with a Philips S5000 at around 110 USD, a Braun Series 5 at around 130 USD, and a Panasonic Arc 3 at around 100 USD. The Xiaomi undercuts all three by 20 to 40 percent while delivering performance that owner reports place within 80 to 90 percent of the bigger names.
For users who shave daily and want a reliable, comfortable, low-maintenance tool with a useful app, the value proposition is strong. For users with very dense beards who shave only every few days and crave the absolute closest cut, a Braun foil shaver still has the edge.

Frequently asked questions
Frequently Asked Questions
Yes, the IPX7 rating supports full wet shaving and rinsing under running water. Avoid prolonged submersion beyond 30 minutes.
No, the shaver works fully without the app. Pairing with the app adds blade-life tracking, replacement reminders, and routine logging, but is entirely optional.
Most users replace the cutting heads every 12 to 18 months. The Mijia app prompts you based on cumulative runtime rather than a fixed calendar interval, which is more accurate for occasional users.
It charges via USB-C from any 5V power source, including a phone charger or laptop, which makes it effectively universal for travel without an adapter.
Xiaomi offers a one-year warranty through authorised AliExpress sellers. Buyer Protection adds a standard return window, and Mijia accessories are widely available for self-service replacement.
Final verdict
The Xiaomi Smart Electric Shaving Razor S302 is one of the most well-rounded budget shavers on AliExpress in 2026. It delivers a comfortable, close shave for the majority of users, ships with a genuinely useful app, and undercuts the established Philips and Braun mid-tiers by a meaningful margin. For daily shavers with light to medium beards who want smart features without the smart-feature tax, it earns a confident recommendation.
