Amazfit Bip U Pro: Design & build

1.43-inch HD màu sắc screen5ATM water resistance with swim tracking24/7 HR monitoringBlood oxygen monitor


The Amazfit Bip U comes with a number of features that, on paper, defy its price point.

A vivid 1.43-inch HD color screen, 5ATM water resistance with swim tracking, 24/7 HR monitoring and even a blood oxygen monitor.

The Bip U Pro also promises 60 dedicated sports modes, along with sleep and stress monitoring plus a custom health evaluation system based upon a number of biometric recordings.

Beyond the fitness realm, there’s an excellent nine-day battery life and some decent điện thoại cảm ứng thông minh connectivity options.

If the feature các mục disregards the price tag, the design and build doesn’t. The silicone strap with plastic fastening is flimsy và doesn’t feel like it will hold up lớn abuse. The strap can also get really clammy.

The plastic body toàn thân construction has large bezels surrounding the 1.43-inch display và there’s a Digital Crown-style button on the right side. It twizzles, but that doesn’t carry any functionality.


At just 31g, you can easily forget you’re wearing this device. But the design lacks an identity and, overall, looks like an táo khuyết Watch knock-off, so be ready khổng lồ field the “oh is that an táo Watch?” The Bip U Pro comes in black, pink and a rather fetching green.

The digital TFT display has a 302 x 302 resolution, is coated by Gorilla Glass 3 and, like the Bip U, drops the transflective display we saw on the Bip S series. It’s a big boost in quality, but clearly it’s weaker than the punchy AMOLED found on the Amazfit GTS 2 Mini.

The cảm biến response is decent, but it can seem a little fiddly at times given the lack of room to operate.

You can also freshen up the look & feel of the watch face from within the watch or download loads of others from the companion Zepp app. It’s also possible khổng lồ create a personalised face using your own photos.

Amazfit Bip U Pro: Activity và sports tracking

GPSPAI score of activity Advanced sleep tracking


Amazfit smartwatches are geared towards activity và fitness tracking, & the Bip U và Bip U Pro have a wide phối of features.

Step tracking is handled with aplomb & accuracy was indistinguishable from that of rivals.

Your activity tracking feeds into the physiological activity indicator, which encourages you lớn hit a PAI score of 100 each week through heart rate-based training.

As you get fitter, it’ll be harder to lớn earn points & you’ll need to lớn train harder to keep your score over 100. It’s a good, generic system for beginners, albeit not as motivating as the táo bị cắn Watch activity rings.


Of course, the 5ATM water resistance makes swim tracking possible at depths of up to lớn 50m. It feels lượt thích Casio had this figured out 30 years ago with $20 digital watches, so we won’t go overboard on the praise here.

Naturally, you’ll also get sleep tracking here, which delves into sleep stages, total sleep và time awake. It will also track naps.

We found the overall total sleep was within ten minutes & registered deep sleep time within six minutes, when comparing with the Whoop Strap 3.0. But against the gold standard sleep tracking of Fitbit and Withings we did find it tended to over-estimate sleep.


You can also turn on advanced sleep tracking, which will impact battery life. You’ll get a sleep score out of 100. Over time, you’ll begin khổng lồ see trends in sleep duration, time to fall asleep & average deep sleep performance, và whether you’re trending up or down.

However, if you don’t want lớn be disturbed all night, you’re going khổng lồ have lớn turn off the motion-based screen wake, which comes in so handy during the day. I almost blinded my wife a couple of times just by turning over in the night. Turning on bởi vì Not Disturb does not prevent the screen waking when the watch detects motion. Annoying.


It’s a good sleep tracking performance, và while we’d urge those looking lớn make meaningful change to lớn consider Fitbit or Withings, this is superb performance và data for the price.

There’s also menstrual cycle tracking, which estimates the next fertile period và estimated ovulation date based upon the information you register. It’s good to see this feature become as much of a staple as step tracking on these devices.

Amazfit Bip U Pro: Workout tracking

60 sports modesGPSStrava support


Hold down the crown & you enter workout mode. You can select from over 60 sports modes, from all of the conventional options khổng lồ dance, cricket, equestrian và curling. Yes, curling. Amazfit is nothing if not inclusive.

After selecting the activity, you can hit start. GPS will be automatically be registered if you’re outdoors và we found no issue with its accuracy or performance.

While heart rate detection is within a good margin of a high-end fitness tracker like Whoop, the estimated calorie burn can be significantly off for certain activities.

In a 55-minute light yoga session, it estimated a whopping calorie burn of 415kcal. The Whoop, meanwhile, went conservative with 134 calories – which is much more realistic.

There’s no real explanation for this anomaly considering both devices registered the average & max HR within a few beats. It seems the disparity may be due lớn the how the individual Amazfit sport modes calculate the data. We’ve requested an answer from Amazfit.


I tried again using the Outdoor Cycling mode on the watch, using the Polar H-10 chest strap and Polar Beat app, as well as the wrist-based Whoop.

For a 25-minute, 4.5 mile cycle the Bip U Pro estimated 286 calories, compared khổng lồ the stingy Whoop (250kcal). Much closer. However, the most-accurate Polar H-10 chest-strap measured 394 calories.

For a newcomer to lớn smart fitness tracking, trusting this calorie burn could present a false sense of accomplishment or even an undercount, if you’re managing calories in/out as part of your fitness and weight loss efforts.

We’d happily recommend this as a fitness tracker for those starting their smart fitness journey, but it’s not quite up to scratch as a dedicated sports watch, if you’re seeking pinpoint accurate next-gen stats.

Amazfit Bip U Pro: Heart rate, stress & blood oxygen tracking

SpO2 sensorStress trackingAccurate resting heart rateInaccurate HR at higher load


The Bip U Pro offers near-continuous heart rate tracking during everyday life. You can pick from a number of intervals, from every minute khổng lồ every half an hour. The last measurement will sit on the homescreen depending on the watch face used. You can also manually measure your heartrate at any time too. It takes around 10 seconds.

Resting heart rate, when measured, was more or less in line with the optical heart-rate sensor on the Whoop Strap 3.0.

Occasionally, it ticked a beat-per-minute or two lower. The same applies lớn the Polar H-10 hardware, when it comes to lớn resting heart-rate. Quite impressive for a device costing $69.99.


When it comes to more intensive exercise, things go downhill quickly. Our cycle comparison against the H-10 chest strap saw a difference in average HR of 10bpm for the session. The Amazfit averaged 136bpm while the chest strap recorded 150bpm. It makes the data less useful for proper analysis or HR zone training – but as this is clearly aimed at casual users, it"s still interesting data for showing how hard you worked.

The ability to measure blood oxygen cấp độ is newsworthy. Those suffering from Covid-19 have experienced dangerously-low blood oxygen levels. Lượt thích respiration rate & HRV with other trackers, your blood oxygen màn chơi can be a vital indicator of your overall wellness.

The oxygen saturation cấp độ is measured manually and takes around a minute. After measuring, you’ll be informed if your SpO2 drops below the optimum level. Be sure lớn follow the on-screen instructions to the letter to ensure an accurate reading.

The găng tracking feature works similarly. It’s measured manually (all-day monitoring can be enabled lớn the detriment of battery life) & pairs with the on-board breathing exercises you can take if high căng thẳng is registered. Haptic feedback & visual cues guide your inhales and exhales.

Amazfit Bip U Pro: Watch UI & experience


This is a well-thought-out interface that is highly customisable and intuitive. Raise your wrist & you’ll see the watch face pop up.

Swiping left & right from the watch face takes you through commonly-used features (Activity Goal progress, HR, SpO2, stress, PAI progress, weather, music controls, Alexa). A swipe down summons quick settings, a swipe up shows điện thoại notifications.

Press the crown for a các mục of features. Hold it khổng lồ enter workout mode. The touchscreen is used to confirm selections. Pretty standard stuff, but it’s also pleasing to lớn see an interface get out of its own way.

You can get dozens of watch faces to keep the look & feel fresh, four live on the watch và the rest can be synced via the Zepp app.

They’re well suited to lớn the different use cases. The activity-themed face shows your HR graph, PAI progress and activity rings, for example. Many can be edited directly from the watch face.

The HR curve graph can be replaced with daily steps, for example.

Amazfit Bip U Pro: Smartwatch features

Alexa on the wristNotifications from smartphoneNo music/payments/calling


Alexa integration is a key tăng cấp over the Bip U watch (GPS is the other). There’s no built-in Wi-Fi or LTE, so voice commands are sent via your phone. You access Alexa with a swipe right from the homescreen and don’t have lớn use the wake word. Of course, that means there’s a microphone on board, which picks up your voice without any trouble.

When this feature works, it’s handy. However, too often we received a “network busy try again later” message. We’ve asked Amazfit to offer some feedback on this.

If you’re playing music via your connected phone, you can control it from a dedicated screen. However, there’s no option to transfer music to the watch for offline playback, no option to add music apps, or to connect bluetooth không dây headphones. You’ll have lớn look lớn the Amazfit GTS/GTR 2 for this, at double the price – và in our testing found the experience lớn be really clunky. Best avoided.

Smartphone notifications lượt thích incoming calls or WhatsApp/Messenger can be turned on via the app, which offers options depending on the apps you have installed.

You can’t act upon the notifications, but they are handy & help you keep the phone lodged in the pocket.

Notifications are generally easy khổng lồ read & clear, but there are a couple of annoying quirks: they can’t display emoji và apostrophes have an unwarranted space after them, which looks a bit untidy.

Amazfit Bip U Pro: Battery life and charging

9 day quoted battery life


Overall, we were really impressed with the battery life offered by the Bip U Pro. The nine-day pledge was accurate with some limited use of GPS for running và cycling và heart rate monitoring set lớn every five minutes. We kept the screen brightness relatively low throughout.

Charging comes via two magnetic pins that click satisfyingly to the rear of the watch. From 13% charge, we got back to lớn 99% in around 85 minutes. Not the fastest charging in the world, for sure, but we’re more forgiving based on how long the battery lasts.
