I used the Fitbit Charge HR for over a year, Mi Band 1s for over 6 months, and have now tested the Mi Band 2 for 1.5 months. I workout 5x a week, try to eat as healthy as possible, attempt to get 6+ hours of sleep a night, and attempt to walk at least 10,000 steps a day. For me, having a fitness tracker is not only fun, it helps me to monitor exactly what habits I am maintaining on a daily basis. In all honesty, I have no real complaints with the Fitbit Charge HR and I still consider it an excellent fitness tracker. However, as an avid Android user (I use the Nexus 6P and stay up to date on all things Android related), I wanted to explore options that would sync with Google Fit and potentially have more room for tinkering. That's where the Mi Band 1s and now the Mi Band 2 enter the picture.
I was able to purchase the Mi Band 2 through GeekBuying.com in late May (it was supposed to be a pre-order) and ended up receiving one week later in the first week of June. I was pleasantly surprised to say the least. Be careful to ensure that you are purchasing an authentic Mi Band 2 (you can google fake vs authentic Mi Band to get a quick overview).
The packaging is simple and almost identical to the Mi Band 1s–just a simple natural colored cardboard box with the band, charger, and manual inside. The band is comfortable to wear, the silicone is soft and flexible, and the included charger is easy to use. After unboxing, I charged my Mi Band 2 for 2 hours and was ready to go. The initial setup slightly more of a pain than I anticipated. The OEM Mi Band software would not connect with my Mi Band. From some research, I was aware that this was a common issue with the Mi Band 1s and 2 because of the less-than-stellar OEM software. The fix? Download "Mi Band Tools" or "Mi Band Notify" from the Google Play store and either of those apps will connect with the Mi Band 2 instantly, thus allowing the OEM software to also detect and connect with the Mi Band 2.
Next thing I noticed? The OEM software stinks. Sure it's fine for displaying steps and sleep data, but that's literally it. The Mi Band 2 is capable of continuous or periodic heart rate monitoring, yet the OEM software only allows for user-activated heart rate monitoring (meaning you have to open the app, press a button, and then it gives you one reading of your heart rate) or only continuous heart-rate monitoring when you choose start a "workout" (some versions of the OEM software have received an update allowing a work-out mode). The problem with the work-out mode is that the information is limited to only the work-out setting and does not integrate at all with your overall tracking stats. I was incredibly disappointed to say the least. If this was the only option for the Mi Band 2, I would give it 1 star and just give up. Fortunately, for Android users, the 3rd party apps "Mi Band Tools" and "Mi Band Notify" open up a whole new world of capabilities for the Mi Band 2 (Mi Band Tools updated their app and the Mi Band 2 is now fully supported; Mi Band Notify is working on providing support for Mi Band 2 still). Personally, after spending some time browsing all the features of the two apps, I ended up going with "Mi Band Tools". With this app, you are able to sync directly with Google Fit, you can set the heart rate monitor for continuous tracking (for workouts, for example), periodic tracking at any interval you please (track heart rate every 10 minutes, 20 minutes, etc), all information is displayed in helpful charts that are highly customizable, you can set vibration alerts for any app, you can set different icons to appear on your screen for any app, and more. Trust me, check out the two apps and you'll be impressed with what your little Mi Band 2 will be able to do!
I'm a nerd over tech stuff, so I decided to wear the Mi Band 2 on one wrist, and my Fitbit Charge HR on the other wrist for two weeks straight to get an accurate comparison of the two bands (I had done the same thing with the Mi Band 1s in the past, and will include small comparisons with the Mi Band 1s as well in this review). After two weeks of steps, workouts, sleep, calorie counting, and heart rate tracking, I was able to draw some general conclusions between the two bands, as follows:
OEM Mi Band software stinks, as I have previously described. Fitbit's software is far superior in every way (social integration, UI, etc). However, with the 3rd party apps available for Android users, the Mi Band 2 becomes a lot of fun to use with plenty of tracking data available. The biggest perk is syncing with Google Fit (for those who care), and the ability to export data onto an excel file (meaning you actually own your information, instead of it being locked into Fitbit's universe). VERDICT: Slight edge to Fitbit because it is simply more polished.
After two weeks of data, my Mi Band 2 consistently tracked slightly less steps than my Fitbit. However, both bands were within 5-7% of each other throughout that time. For what it's worth, when comparing the step counts with my Google Fit's count measured directly from my phone, my phone's step count was also lower than my Fitbit and closer to the count provided by my Mi Band 2. VERDICT: Draw
The Mi Band 2 seemed to be less accurate with sleep tracking. The Fitbit was able to track restless sleep and when I was awake more accurately. The Mi Band 2 had the tendency to over calculate the amount of sleep I was getting, and failed to detect that I was awake multiple times while in bed (i.e., reading in bed). However, the Mi Band 2 did a fine job of calculating deep sleep vs light sleep, and for the most part, results were quite accurate in comparison to Fitbit. Verdict: Fitbit does a better job with sleep tracking.
The Mi Band 2 simply under calculates the amount of calories burned throughout the day. For one, it only measures calories burned with respect to how many steps you took during the day, and does not factor in your BMR (basal metabolic rate, which includes how many calories you burn normally in a day depending on your weight, etc). It appears to simply use a generic calculation that every 1000 steps is roughly equivalent to 50 calories burned. Fitbit on the other hand takes into consideration steps, BMR, and heart rate (to some extent). VERDICT: Fitbit does a better job with calorie tracking.
HEART RATE TRACKING:
Both bands are relatively inaccurate in tracking heart rate due to technological limitations (you can't compare bands on your wrist to heart rate sensors that wrap around your chest). However, once your expectations are adjusted, I was able to see that both the Mi Band 2 and Fitbit Charge HR did pretty good jobs with accurately tracking my overall and general heart rate throughout the day. In fact, the Mi Band 2 did a slightly better job of providing accurate heart rate readings. My Fitbit Charge HR tends to under detect my heart rate, especially during workouts. However, the Mi Band 2 was able to track my elevated heart rate during intense resistance training exercises much better. VERDICT: Mi Band 2 does a better job with heart rate tracking.
Easy. Mi Band 2 lasts WAY longer. Fitbit Charge HR averages 3-5 days. Mi Band 2 averages 10-35 days depending on the frequency you set for the heart rate tracking. With heart rate tracking limited to just workouts, I was able to go 31 days and still had 9% battery life left. With heart rate tracking every 7 minutes, I am currently at 14 days with 42% battery life. VERDICT: Mi Band 2 is much more efficient with battery life.
OVERALL WINNER: In my mind, the Fitbit Charge HR is still more polished and ready to go, and under objective standards, it is the clear winner. The OEM software is excellent, the band is comfortable to wear, all tracking is pretty accurate, and there is nothing really to complain about. However, if you are looking for a fitness tracker that is far more affordable with almost all the same features (Fitbit Charge HR is able to track stairs and elevation; Mi Band 2 is unable to), then the Mi Band 2 may be the right one for you. I personally value the ability to track my fitness data on Google Fit (rather than have it all locked on Fitbit's software platform), and the ability to tinker with how often I track my heart rate, etc. As a result, subjectively, I like the Mi Band 2 more. In terms of the difference between the Mi Band 2 and Mi Band 1s, I would say it really just comes down to having the screen (and you don't sacrifice battery life at all with having the screen because the battery is likely larger in the Mi Band 2. I actually got slightly less battery life out of the Mi Band 1s on the same tests); and the Mi Band 2 does not appear to be plagued with the issue of the tracker popping out of the silicone band unintentionally (this happens occasionally to the Mi Band 1s). Other than that, the Mi Band 1s and Mi Band 2 track the same things.
***Fun Tip: Another perk of the Mi Band 2 is that I was able to sync it with Endomondo to serve as a continuous heart rate monitor for my workouts and bike rides. As far as I know, this is not possible to do with the Fitbit.
Since the HR portion did not work on my skin I did test the other function and they worked pretty good. The step counter was inaccurate but that's always expected on any step counter. The screen is nice and solid, easy to read and the band easily fit on my big wrist. Here are some highlights of this band below:
- light weight
- material feels great agaisnt the skin and band does not pop off during exercise
- Screen is easy to read
-It has vibration features
- Sleep tracking seemed to work well using the dedicated app
- HR sensor does not work against darker skin (Beta testers with Melanin must not have existed)
- Step counter was OFF, by the time I estimated around 300 steps, the counter showed about 700
- The app could be smoother, it's just OK.
I still stand by Xioami products 100% but this band did not work well for me.
Other things: band is comfortable enough, design is fairly innocuous and could be changed with the very wide range of accessory bands that work with it. No problems with sweat, seems to stay clean and dry. I wear it on my right wrist and don't have the gesture-triggered time display running because I like to wear a regular mechanical watch on my left wrist. Not sure how much of an effect turning that off has on the battery but I'm getting over a week of battery life on it. I'm also using Mi Band Tools from the android store, which gives an amazing amount of control to alarms and other functionality which extends the capabilities. I recommend running Mi Band Tools and Mi Fit simultaneously to get the most out of it. Doesn't seem to affect my phone's battery life too much either. Still, I wish there were more ways to connect the band directly to some of the other health apps out there, or to tinker with it directly myself.
