About the Xiaomi Watch S5 46mm
The Xiaomi Watch S5 46mm is the traditional-looking end of Xiaomi's wearable range: a 316L stainless steel round watch that runs Xiaomi's own HyperOS 3 rather than Wear OS, and trades app breadth for endurance. That trade pays off, because Xiaomi quotes up to 21 days in light use and around nine days with the always-on display running, which puts it in a different league to most Wear OS watches you can pair with an Android phone. The 1.48-inch AMOLED panel peaks at 2,500 nits, so it stays legible on a bright day, and the case is slimmer than the aluminium Watch S4 it replaces despite the heavier steel construction. Fitness tracking is the other focus, with dual-frequency five-system GNSS, offline colour maps with route and back-tracking navigation, a genuinely useful cycling mode that can pair with Bluetooth power meters, and a four-LED heart rate sensor. It works with both Android and iPhone, which the Wear OS models cannot claim. Independent long-term testing of the sleep and heart rate accuracy claims is still limited, so treat Xiaomi's own lab figures as a guide rather than gospel.

Frequently asked questions
Is the Xiaomi Watch S5 46mm worth buying?
It is worth buying if battery life and outdoor tracking matter more to you than apps. You get up to 21 days of light use, dual-frequency GNSS with offline maps and a stainless steel case, but HyperOS 3 has nothing like the Google Play app library found on Wear OS watches.
How long does the Xiaomi Watch S5 46mm battery last?
Xiaomi rates the 815mAh battery at up to 21 days in a light usage scenario, 14 days in normal use and around nine days with the always-on display enabled. Those are lab figures, so heavy GNSS workouts and frequent Bluetooth calls will shorten them.
Does the Xiaomi Watch S5 46mm work with an iPhone?
Yes. It supports phones running Android 8.0 or later and iOS 14.0 or later through the Mi Fitness app. Some features, such as the sports vlog remote recording mode, only work with Xiaomi, Redmi and Poco handsets.
Can you swim with the Xiaomi Watch S5 46mm?
Yes, it carries a 5ATM water resistance rating, equivalent to 50 metres, so pool and near-shore swimming are fine. Xiaomi advises against hot showers, saunas and diving, and notes that water resistance degrades over time.
Does the Xiaomi Watch S5 46mm have contactless payments and GPS?
It has NFC contactless payments supporting Mastercard and Visa, subject to regional availability, plus built-in dual-frequency GNSS covering GPS, Galileo, GLONASS, BeiDou and QZSS. It also stores full-colour offline maps for route navigation without your phone.
Should I get the Xiaomi Watch S5 46mm or the Xiaomi Watch 5?
Choose the Watch S5 46mm for battery life and iPhone support, since it runs HyperOS 3 and lasts weeks rather than days. Choose the Xiaomi Watch 5 if you want Wear OS by Google, Gemini, Google Wallet and Maps on your wrist, and can live with roughly six days per charge and Android-only pairing.
