New Delhi: Smartwatches and fitness trackers market has grown by leaps and bounds in the past few years with features like SpO2 monitoring taking the centre stage, especially after the global COVID-19 pandemic. In fact, fitness trackers are also trying to squeeze in as many features as possible into the activity bands to appeal to the ever-burgeoning wearables consumers.

Xiaomi, one of the most popular smartphone makers, is a known name when it comes to making smartwatches and activity bands, and its sub-brand Redmi and Xiaomi itself have launched a decent line of wearables to date with the most interesting one being the Redmi Smart Band Pro. The Redmi Smart Band Pro is available in the country at a price point of Rs 3,999 but was initially available at an introductory price of Rs 3,499 too.

The Redmi Smart Band Pro is a hybrid between a smartwatch and a fitness Band and a significant upgrade from the Redmi Smart Band that was unveiled in India in April 2020. Interestingly, Huawei Band 6 which was recently unveiled in India also followed the same hybrid functionality between a smartwatch and a fitness tracker. Here is how the Redmi Smart Band Pro fared in my review.

Redmi Smart Band Pro Design, Display, Looks And Build

The Redmi Smart Band pro arrived in a fairly slim rectangular box with contents like a proprietary magnetic charger and some documentation. The inclusion of a magnetic charger at this price point is worth mentioning. The display is smaller than the Mi Band 6.- it is a 1.47 inch AMOLED screen that is wide and bright enough and gave enough real estate. The screen also has a peak brightness of up to 450 nits which ensured I could view the display properly under direct sunlight. The sheer size and quality of the AMOLED screen make it one of the best displays in a budget activity tracker segment. Thanks to the ambient sensor and automatic brightness, the screen automatically adjusted depending on the surrounding conditions such as direct sunlight and normal outdoor conditions.

The casing of the Redmi Smart Band Pro is made out of good quality plastic with a matte finish. At 25.5 grams, the Redmi Smart Band Pro is a charm to wear to bed, for long hours of workouts and exercises. The silicon straps can be detached easily and are good quality ones. The straps are made out of TPU (Thermoplastic Polyurethane) which is essentially a mix of plastic and rubber. The TPU straps were easy on my skin and did not cause any rashes or breakouts and depending on the size of one’s wrists, the straps can be adjusted from 130mm to 220mm sizes. I reviewed the black coloured one as that is the only variant available right now, but I expect Redmi to add more colour variants in the future.

Redmi Smart Band Pro Features, Battery And Performance

The Redmi Smart Band Pro features a 200mAh battery which it claims can last up to 14 days. I used the Band with features such as heart rate monitoring, stress tracking, SpO2 monitoring, menstrual cycle tracking, step count. Please note that stress tracking has to be turned on via the Xiaomi Wear app and it does affect the battery life. With all the mentioned features on, the battery lasted for almost a week which is commendable. With basic usage, the battery lasted the promised 14-day time. I would like to mention that the menstrual tracking feature is also there which was a bit of a miss. However, I am expecting this feature to get better with the upcoming iterations. Step count was almost accurate on the Redmi Smart Band Pro and one can also set a daily goal of steps on the Band. However, it would have been better if the Band also featured an in-built GPS.

There is also an option to show other notifications and one will have to enable it via the Xiaomi Wear app. However, it can be a pain to enable the notifications for each app one by one as they have been enabled by default. In terms of activity tracking, the Redmi Smart Band Pro features more than 100 multi-sports modes and the most prominent ones are outdoor running, walking, trekking, treadmill, trail run, outdoor cycling, indoor cycling, pool swimming, freestyle, yoga and jump rope among others. The Band also features 5 ATM water resistance, thus, making it suitable for swimming and water activities. Apart from the five built-in watch faces, the Band also supports a range of watch faces that can be chosen via the app.

The Redmi Smart Band Pro can be paired with the Xiaomi Wear app and the Apple Health and Strava apps too. Much like what we have seen in the Apple Watch, the Redmi Band Pro also displays the number of times you stand, daily exercise minutes and calories burnt, thus, also motivating the user to keep moving at intervals.

Redmi Smart Band Pro Final Verdict

The Redmi Smart Band Pro is the best activity Band available in the market right now that tries to give the feel of a smartwatch with its big display at this price point. The addition of menstrual tracking, 5 ATM water resistance and stress tracking make the deal even sweeter for those who are proactively looking to improve their overall health.

Redmi Smart Band Pro Review

Xiaomi recently launched the Redmi Smart Band Pro in India alongside the launch of the Redmi Note 11 Series and Redmi Smart TV X Series. The Redmi Smart Band Pro is a fitness Band with a 1.47-inch AMOLED touch display, real-time heart rate monitoring, SpO2 tracking, and LifeQ health algorithm, and offers 14 days of battery life. The Redmi Smart Band Pro is the advanced variant of the entry-level Redmi Smart Band launched last year. Here’s our Redmi Smart Band Pro review.

Design, Display, Build

The key highlights of the Redmi Smart Band Pro are its large 1.47-inch AMOLED display, real-time heart rate monitoring 24 hours a day, SpO2 tracking, 110 workout modes, LifeQ health algorithm, and Women’s menstrual health tracking. Compared to its tone-down variant, the Redmi Smart Band, the primary changes we can see are its display, better design, a SpO2 meter, and a chunk of fitness features.

About its design, the Redmi Smart Band Pro has a 1.47-inch AMOLED touch display with 194 x 368 pixels resolution, 283 ppi, 450 nits brightness with automatic brightness adjustment. Since it has a large display, the screen-to-body ratio is 65.5% and it has a water-resistant design with up to 5ATM. The rest of the design has a matte finish and appears to be of good quality.

You won’t find any buttons on the Band, the Redmi Smart Band Pro has a touch screen that is used to interact with the user interface. The bottom side has a couple of sensors, a heart rate sensor, and a SpO2 sensor alongside the charging pins with a USB magnetic charger that sticks in.

On pressing the buttons on the straps, you can remove them easily and change them to your liking, different types of straps are available for different styles and for different occasions. Charging is easy, just plug the magnetic USB charger on the back.

Software, User Interface, Features

The Redmi Smart Band 2 offers a customized fitness Band interface, it has proprietary software that comes with built-in features along with Watch Faces that you can use to customize the homescreen. On the hardware side, it equips an Ambiq Apollo 3.5 System-on-chip with 8 MB RAM and 128 MB internal storage and uses Bluetooth 5.0 BLE for connectivity.

To pair the Redmi Smart Band Pro, you will need to install the Xiaomi Wear app on your smartphone and follow the pairing instructions, it is compatible with Android 5.0 or iOS 10.0 and above operating systems. The sensors on the Band include a 6-axis sensor, PPG Heart rate sensor, SpO₂ sensor, vibration motor, ambient light sensor.

The Redmi Smart Band Pro has a bunch of features to offer, it has always-on heart rate motoring that runs all day long 24 hours, SPO2 tracker that tracks your Bood Oxygen levels with continuous night-time monitoring, and a LifeQ Health Algorithm that tracks health vitals accurately. The Smart Band vibrates to send an alert when your heart rate falls out of the safe zone. According to the company, the Redmi Smart Band Pro offers all-round tracking across four pillars of health vitals i.e. Activity, Cardiovascular, Fitness, and Sleep by using the LifeQ algorithm.

The fitness tracker has more than 110 workout modes with 3 auto-detect modes – Running, Treadmill, and Walking, along with Sleep Monitoring, Breathing Exercises, Stress Monitoring, and Women’s menstrual health tracking. It helps track your menstrual health with predictive reminders for your period cycles. You can keep comprehensive records and track your cycles, ovulation fertile days on the Xiaomi Wear App.

T he interface isn’t quite responsive if you interact with the Band too fast, a little sluggishness is observed, we assume it may resolve in the upcoming firmware updates. We tried the basic workout modes and they worked exceptionally well. O ther functions include Message/call notification, App alerts, Calendar, Alarm, Clock, Stopwatch, Timer, Music control, Find phone, Unlock phone (MIUI), Camera remote shutter, Weather, Set activity goals, and more.

Battery Life Charging

Moving to its battery life, the fitness Band can easily last longer even though it has a big screen and a bunch of fitness perks. On a single charge, the Band runs up to 14 days, it varies depending on your usage, but as a daily driver, you can expect the battery life this long. That eventually means, you only need to charge it twice a month (or thrice).

The Redmi Smart Band Pro packs a 200 mAh battery, much higher than its tone-down variant, and it takes about 1.5 hours to charge from 0% to 100%. It has a USB Magnetic charger that connects seamlessly, once fully charged, you can use it for up to 20 days in power saver mode.

Pricing Availability

The price for the Redmi Smart Band Pro starts at ₹3,499 (limited offer) and is available from 14th February 2022 on Mi.com, Mi Home stores, Amazon India, and other offline retail outlets.

Redmi Smart Band Pro: Verdict

The Redmi Smart Band Pro offers a great value, it has all those fitness Band features you need, you get a large Always-on screen, a water-resistant design, real-time heart rate monitoring (24 hours), SpO2 measurement, and it runs as long as 14 days on battery on a single charge. The only downside is that it doesn’t offer a dedicated GPS, it uses your smartphone’s location services for tracking. But given the price, it has most features you see in an advanced fitness tracker. At the price of ₹3,499 (offer price), the Redmi Smart Band Pro is a recommended buy.

Xiaomi Smart Band 7 Pro review: The Mi Band grows up

While not quite worthy of insta-buy status like the regular Mi Band 7, the snazzier Smart Band 7 Pro still earns its slightly higher asking price with value additions like built-in GPS and a larger, smartwatch-style display.

What we like

Elegant, smartwatch-style design

Larger, equally high-quality display

Robust workout and health tracking

Reasonably accurate built-in GPS

What we don’t like

Inconsistent sleep tracking

Limited Pro Smart features

Mi Fitness app needs work

Xiaomi Smart Band 7 Pro

Xiaomi’s beloved line of Mi Band fitness trackers is synonymous with affordable pricing. What really makes them special, though, isn’t the low barrier of entry, it’s the value you get in return. The Xiaomi Mi Band 7 nudged the series’ price up by around ~10, but tweaks to the formula like a brighter, larger, always-on display and improved health tracking metrics ensured it was still a steal. But for the first time, it wasn’t the only option from the Beijing juggernaut. Xiaomi had a model with further upgrades and a smartwatch-styled look waiting in the wings.

Does the bigger, better, and bolder Mi Band 7 Pro — a.k.a. the Smart Band 7 Pro on the global stage — stretch that value proposition too far? Find out in Android Authority’s Xiaomi Smart Band 7 Pro review.

About this Xiaomi Smart Band 7 Pro review: I tested the Xiaomi Smart Band 7 Pro over a period of 10 days. The unit was provided by Xiaomi for this review.

What you need to know about the Xiaomi Smart Band 7 Pro

The vanilla Smart Band 7/Mi Band 7 launched in Europe in late June 2022, but mere days later Xiaomi unveiled its second fitness tracker of the year — the then China-exclusive Xiaomi Mi Band 7 Pro. It took another four months for the newly-monikered Smart Band 7 Pro to make its way to the West.

As the first in the series to carry the Pro affix, the Smart Band 7 Pro expectedly brings a little more to the table than Xiaomi’s basic tracker as it looks to blur the lines between fitness Band and budget smartwatch. Gone is the pill-shape design and wrap-around silicon Band, replaced by a rectangular face with a 1.64-inch 2.5D display, a shiny metal-coated frame, and quick-release bands. The bands are also joined with a traditional jewelry clasp as opposed to the Band 7’s pin-in-hole buckle.

The Smart Band 7 Pro sees Xiaomi looking to blur the lines between fitness Band and budget smartwatch.

While some of the changes to the wearable’s feature set are more subtle than you might expect for a “Pro” model, the Smart Band 7 Pro does bring some notable additions such as built-in GPS support and an ambient light sensor. It also houses a larger battery (235mAh, up from 180mAh on the Band 7) in an attempt to offset the larger display.

Xiaomi’s health and fitness suite is carried over almost wholesale from the Band 7, including continuous blood oxygen (SpO2) monitoring, 24-hour heart rate monitoring and alerts, sleep, stress, and basic menstrual cycle tracking. This is complemented by a ridiculously expansive 110 different activities to track. On-board apps will also be familiar, though the global model does support Amazon’s Alexa voice assistant out of the box when enabled via the Mi Fitness companion app, though there are reports that this won’t work in the US.

The Xiaomi Smart Band 7 Pro comes in either Light Gold (pictured) or Graphite Gray, either of which can be combined with a variety of strap colors. Faux-leather straps in Pine Green or Moon Gray are also seemingly available, though I couldn’t find these on sale anywhere.

As with other Xiaomi fitness trackers, you can’t officially buy the Smart Band 7 Pro in North America, however, you can grab one via Amazon sellers or through import sites without much trouble.

What’s good?

The Mi Band series has always managed to wear more hats than you’d expect for such a cheap range of fitness trackers, but its actual wardrobe has always been a bit lacking. After seven generations of boring black pills, the Smart Band 7 Pro throws off its fitness Band shackles and looks like a bonafide smartwatch; one that’s just as suited to a brisk morning jog as it is for casual or Smart wear at any time of the day.

My Picks for the Best Budget Fitness Tracker of 2023!

While the polycarbonate rear does threaten to undermine its premium feel, the pronounced, curved case and metal-coated chassis are enough of a visual distraction for anything less than a really close inspection. The latter will definitely scratch easier than a true metal frame, but based on my experience it’ll take a few bumps and bruises before showing any obvious wear. The tempered glass also held up despite a few light knocks, and the anti-fingerprint coating kept any sweaty smudges to a minimum.

Despite its increased size and weight, the Smart Band 7 Pro doesn’t feel any heavier on the wrist. As a long-time Mi Band 6 user (and Mi Band 3 before it), I can safely say that the additional bulk doesn’t register at all. While it might have been nice to see the addition of a crown or button — especially now that there’s ample room — for an extra input option and to complement the more sophisticated aesthetic, Xiaomi’s swipes and gestures do the job just fine at this price tier.

The stretched display offers a pleasant increase in screen real estate without necessitating a much larger form factor. The quality is still great too; the 2.5D glass falls elegantly into the frame, disguising bezels that, while not exactly thin, are easily ignored. Credit to Xiaomi for also increasing the screen resolution to match the pixels per inch total of the regular Band 7. As a result, it’s just as crisp and bright (with a peak 500 nits), while benefitting from the Pro-exclusive ambient light sensor that will dynamically adjust the brightness to match your surroundings.

Xiaomi claims that the Band 7 Pro is 50% larger than the vanilla Band 7. Big numbers are one thing, but there’s an immediate practical advantage in that the extra space allows for two vertical rows of apps instead of one. The app title text is gone, so you will need to remember what all the icons mean in the drawer. However, that’s a small price to pay for not needing to scroll as fervidly to get to the correct workout type when you’re warmed up and ready to go. The rest of the UI has also been tweaked for the larger scale, and though the result looks even more like a watchOS wannabe now, I can think of worse decisions than mimicking the most popular smartwatch platform. The watch faces are also far more fun, with some nicely scaled repeats and some that are exclusive to the larger Band 7 device.

There’s plenty to like on the health and fitness front — hardly a surprise when it lifts the Band 7’s winning formula almost wholesale. Resting and active heart rate tracking proved accurate enough when tested against control devices. As well as heart rate alerts, the Band 7 Pro’s SpO2 tracking can also warn you if your blood oxygen drops below 90%. It’s certainly not a medical-grade device, but having continuous SpO2 monitoring in the first place isn’t a given at this price tier. There are tons of different activity modes too. Perhaps too many, frankly, but I’m sure someone out there is specifically looking to dig deep into their checks notes snowmobile workout statistics. It’s also handy to have automatic workout detection for common activities — namely running, walking, treadmill, rowing, and elliptical training.

The biggest upgrade to the fitness suite for the Smart Band 7 Pro is built-in GPS. No longer do Mi Band users need to lug around their phones to get a full picture of their route and related distance stats. It performs well, too. It takes a few seconds to get a location lock, but after that, I didn’t encounter any issues with connection dropouts outdoors throughout my testing. As for accuracy, the graph above shows a comparison walking route with my Galaxy Watch 4. While neither device is fully on point — both veer into people’s houses on occasion — the Band 7 Pro stuck far more closely to the actual path I took. Notably, it also picked up on my location far quicker than Samsung’s premium wearable, as you can see from the delayed blue start line.

Battery life is best looked at as a glass-half-full situation. It’s certainly worse than the Band 7, which managed around a week in our testing with advanced tracking features turned on. By comparison, the Xiaomi Smart Band 7 Pro managed around three days with the always-on display (AOD) active, continuous heart rate, sleep, and SpO2 monitoring turned on, and tracking a daily workout using the built-in GPS. The latter is the biggest drain, with a loss of around 10% battery after an hour-long walk.

Xiaomi claims that the Smart Band 7 pro can go upwards of 12 days at a push. That might be true if you turn off all of the tracking and the AOD, but I’m not sure that’s necessary. Switching off the AOD alone and falling back on the reliable raise-to-wake gesture immediately boosted endurance by a couple of days, and even two or three days on a single charge is far from the worst we’ve seen from smartwatch-type trackers.

What’s not so good?

For a wearable that has “Smart” and “Pro” in the name (at least in the West), the Xiaomi Smart Band 7 Pro is kind of, well… dumb… and basic. It might look fancier than the regular Xiaomi Mi Band 7, but when stripped to its essentials, the functionality is identical, and with no app store present, there’s no way of adding new apps at all. This creeping sense of familiarity sadly extends to the underbaked sleep tracking, which is incredibly finicky about when it actually kicks in. It also offers very little in the way of advice or feedback about your sleep patterns.

Furthering the non-Pro feel is the inability to make mobile payments due to the lack of NFC outside of China. There’s still no speaker, either, so no calls, verbal workout coaching, or message alerts beyond vibrations. And those vibrations are fearsome, and not in a good way. If the Smart Band 7 Pro is resting on a table and it gets a ping it sounds like a pneumatic drill has gone off; it’s one of the few areas where the Smart Band 7 Pro feels cheap.

The Smart Band 7 Pro is technically compatible with two different apps, but neither offer the full package you’d hope for.

However, the real headaches come when you boot up the Xiaomi Smart Band 7 Pro’s companion app. The device pushes you towards the Mi Fitness app (formerly Xiaomi Wear) via a QR code on startup, and that’s for a good reason because unlike older Mi Bands, the Smart Band 7 Pro is, at the time of this writing, seemingly not compatible with Zepp Life, f.k.a. Mi Fit — the original Mi Band phone app. This is a bit confusing when you consider that the regular Mi Band 7 can sync up with Zepp Life just fine, but it becomes even more so when you realize that there isn’t feature parity between the two. For example, Mi Fitness is locked to the metric system and cannot sync with Google Fit — two things that all other Mi Bands can do via Zepp Life, should you wish.

It should be said that the Mi Fitness app offers a more pleasant visual experience due to the Apple-like UI and houses all of the watch face customization options. However, I’ve always found the ever-faithful Zepp Life to be much clearer and less fussy with its presentation of fitness data and workouts. While you could never use both at the same time anyway, the missing features in Mi Fitness stick out even more when you don’t have any other option.

Finally, while performance around the UI is generally slick when swiping between apps and workout modes, the notifications tray is a whole other story. Sometimes it just froze momentarily in my testing, but almost all of the time it lagged and stuttered when attempting to scroll between messages.
