Detailed Reviews
1. Amazfit Bip 5 - Best Overall Smartwatch Under £50 (£44.99)
The Amazfit Bip 5 is the best budget smartwatch you can buy in the UK right now. It packs a large 1.91-inch AMOLED display, built-in GPS with support for four satellite systems, and over 120 sport modes into a lightweight design that weighs just 26 grams. The 10-day battery life means you charge it roughly three times a month.
Health tracking is comprehensive for the price. You get 24/7 heart rate monitoring, blood oxygen (SpO2) spot checks, stress level tracking, and detailed sleep analysis through the Zepp app. The app itself is polished and provides clear, actionable health insights without overwhelming you with data.
The Bip 5 also supports Alexa voice assistant, phone call answering via the built-in speaker and microphone, and quick replies to messages on Android. At £44.99, it delivers more features than some watches costing twice the price.
Pros: Built-in GPS (4 satellite systems), large AMOLED display, Alexa support, phone call answering, lightweight
Cons: SpO2 accuracy is approximate, no NFC payments, speaker quality is tinny for calls
2. Xiaomi Redmi Watch 4 - Best Display (£44.99)
The Xiaomi Redmi Watch 4 has the largest screen on this list at 1.97 inches, making it the easiest to read at a glance. The AMOLED display is bright and vibrant with an always-on display option, though using it reduces the 12-day battery life to around 6 days. Build quality is impressive, with an aluminium alloy frame that feels more premium than its price suggests.
GPS tracking supports five satellite systems, giving it slightly better outdoor accuracy than the Amazfit Bip 5 in testing. The Mi Fitness app provides detailed workout analysis, and the watch supports over 150 sport modes. Health features include heart rate, SpO2, stress, and sleep tracking.
The main downside is that the larger display makes it slightly bulkier on slimmer wrists. If that does not bother you, the Redmi Watch 4 is an excellent alternative to the Amazfit Bip 5.
Pros: Largest and brightest display, premium aluminium build, 5-system GPS, 12-day battery, always-on display
Cons: Slightly bulky, always-on display halves battery life, Mi Fitness app less polished than Zepp
3. Huawei Band 9 - Best for Fitness Tracking (£29.99)
The Huawei Band 9 is technically a fitness band rather than a smartwatch, but it outperforms most budget smartwatches for fitness and health tracking accuracy. Huawei's TruSeen heart rate sensor is widely regarded as the most accurate at this price point, as noted by Wareable in their detailed testing.
The slim, lightweight design (14 grams without strap) makes it the most comfortable option for 24/7 wear, including sleep. Battery life is an outstanding 14 days with typical use, and the 1.47-inch AMOLED display is bright and responsive despite the compact size.
The trade-off is the smaller screen and the lack of built-in GPS. You will need to carry your phone for GPS-tracked outdoor activities. If you primarily exercise indoors or do not need precise route mapping, this will not matter.
Pros: Most accurate heart rate at this price, 14-day battery, ultra-lightweight, excellent sleep tracking, very affordable
Cons: No built-in GPS (connected GPS only), smaller display, limited smart features compared to watches
4. Samsung Galaxy Fit 3 - Best for Samsung Phone Users (£39.99)
If you own a Samsung Galaxy phone, the Galaxy Fit 3 integrates seamlessly with Samsung Health, SmartThings Find (for locating lost devices), and Samsung's notification system. The 1.6-inch AMOLED display is bright and easy to read, and the 13-day battery life is among the best in this comparison.
Samsung Health is one of the most mature fitness apps available, offering detailed workout analysis, body composition estimates (when paired with a Samsung phone), and integration with other Samsung health devices. The Galaxy Fit 3 also supports Samsung Wallet for contactless payments on select models, a rare feature at this price.
For non-Samsung users, the value proposition weakens. Some features are Samsung-exclusive, and the companion app experience is better with a Galaxy phone. In that case, the Amazfit Bip 5 or Xiaomi Redmi Watch 4 offer more standalone value.
Pros: Excellent Samsung ecosystem integration, 13-day battery, Samsung Health app, potential NFC payments, slim design
Cons: Best features require Samsung phone, no built-in GPS, fewer sport modes than competitors
5. Fitbit Inspire 3 - Best for Sleep Tracking (£49.99)
Fitbit pioneered consumer fitness tracking, and the Inspire 3 benefits from years of algorithm refinement. Sleep tracking is where Fitbit genuinely excels. The Sleep Score feature provides a single number (1-100) summarising your sleep quality, while detailed breakdowns show time in each sleep stage, restlessness, and oxygen variation. The Fitbit app's sleep insights are the most actionable of any tracker at this price.
Active Zone Minutes is another standout feature, rewarding you for time spent in fat-burn, cardio, and peak heart rate zones based on your personal fitness level. This is more motivating than raw step counts for many users. The 10-day battery life and comfortable slim design make it easy to wear around the clock.
At £49.99, the Inspire 3 is the most expensive option here, and some Fitbit Premium features are locked behind a subscription after a trial period. The free tier still provides excellent value, but it is worth noting.
Pros: Best sleep tracking available, Active Zone Minutes, excellent app with health insights, comfortable 24/7 wear
Cons: Most expensive on this list, some features require Premium subscription, no built-in GPS, smaller display
6. Amazfit Band 7 - Best Value and Battery Life (£27.99)
The Amazfit Band 7 is the best budget option for anyone who wants maximum battery life and core tracking features at the lowest possible price. An 18-day battery life means you charge it roughly twice a month, which is the longest here by a comfortable margin. The 1.47-inch AMOLED display is identical in size to the Huawei Band 9 and perfectly usable for notifications and workout data.
For under £28, you get 120 sport modes, 24/7 heart rate and SpO2 monitoring, sleep tracking, stress tracking, and smartphone notifications. The Zepp app provides clear health summaries and trend analysis. It lacks built-in GPS and the heart rate sensor is a step below Huawei's TruSeen technology, but at this price, those are reasonable trade-offs.
Pros: 18-day battery life, very affordable, 120 sport modes, good Zepp app, AMOLED display
Cons: No built-in GPS, heart rate less accurate during intense exercise, basic notification support
What Features Matter Most Under £50?
Battery Life
Budget smartwatches range from 10 to 18 days of battery life in this guide. If you hate charging devices, prioritise this. The Amazfit Band 7 (18 days) and Huawei Band 9 (14 days) lead the pack. Using features like always-on display, continuous GPS tracking, or frequent SpO2 checks will reduce battery life significantly.
GPS: Built-in vs Connected
Built-in GPS means the watch tracks your route and distance without your phone. Connected GPS uses your phone's GPS through a Bluetooth connection. If you run, cycle, or walk outdoors and want accurate distance and route data, built-in GPS (Amazfit Bip 5 or Xiaomi Redmi Watch 4) is worth paying slightly more for.
Heart Rate Accuracy
All six options offer 24/7 heart rate monitoring, but accuracy varies. The Huawei Band 9 and Fitbit Inspire 3 produce the most consistent readings during exercise. For casual health tracking, all options are adequate. For heart rate zone training, accuracy matters more.
Display Size
Larger displays (Amazfit Bip 5 at 1.91", Xiaomi Redmi Watch 4 at 1.97") are easier to read and show more information per screen. Smaller fitness band displays (Huawei Band 9, Amazfit Band 7 at 1.47") are more discreet and comfortable but require more scrolling.
Honest Limitations of Budget Smartwatches
It is important to set realistic expectations. Budget smartwatches under £50 will not:
- Replace a dedicated running watch for serious training (GPS accuracy and advanced metrics are limited)
- Provide medical-grade health data (SpO2 and heart rate readings are estimates, not diagnostics)
- Offer the app ecosystem of an Apple Watch or Wear OS device (no third-party apps)
- Support standalone music playback or offline Spotify (you need your phone)
- Last as long as premium watches in terms of build durability (2-3 years vs 4-5 years)
If any of these are dealbreakers, you will need to increase your budget to the £100-200 range for watches like the Amazfit GTR 4 or Samsung Galaxy Watch FE. For the full breakdown, read our guide to whether cheap smartwatches are worth it.
