Design, Build and Comfort
The Lenovo Cardio 2 comes with a simple, bracelet-like design, which is subtle and looks pretty good. It has a detachable strap that can be pulled off to reveal a USB plug for charging on the tracker unit itself. This means that the fitness band can be charged by plugging it directly into any USB charger.
The company has not used any metal piece to build this tracker, which make it very lightweight and comfortable. So sleeping with the band on was no problem. The strap is black and made of silicon. It’s looking very stylish and modern but missing the softness.
The central module features the display as well as the optical heart rate sensor. Like most other trackers in this price range, the Cardio 2 features a single touch-sensitive button just below the display that is used to on/off or controls the device. The display is quite stealthy and is only visible when it is on. The 0.78-inch OLED display is not large but enough for the easy reading. In, direct sunlight, brightness is adequate enough to check the activity numbers, but not good enough to read caller id and messages. There is also an option in the app to control the brightness level.
Turn the tracker around and you’ll see the heart rate sensor at the back. When Auto Measure is turned on, the sensor emits a sharp green blinking light. This doesn’t get disabled automatically when you take the band off and can be annoying. You have to turn it off yourself through the Lenovo app.
One of the highlights of this fitness band is the 5ATM rating, which means is water resistance up to 50 meters.
The Lenovo claims to offer a battery life of 20 days on a single full charge. In terms of real-world usage, however, the Cardio 2 managed to last around 8-9 days, which is quite acceptable.
The Interface is almost same as other fitness bands. You get all the info on display, which you need on the go. The first screen serves as a watch face, as usual. Behind the watch is the number of steps taken, calories burned, heart rate, find my phone and weather. You don’t get sleep hours detail on the tracker display.
The Cardio 2 could display the name of the sender for messages we received on WhatsApp, but it wasn’t easy to read on the tiny display. For incoming calls, the tracker would display the number scrolling across the tiny screen instead of the contact name for numbers saved in our contact list, which wasn’t very helpful.
Connectivity & Application
It can be connected with all the android phones and iPhones within a few seconds. First, you need to turn on the tracker just pressing touch button for three seconds. Then download the ‘ Lenovo Life ‘ app from play store or iTunes.
The connection prosses is very simple with just 2-3 onscreen steps. Once paired, you can navigate through the app’s various information and settings. The app lets you access records like the steps taken, calories burned, heart rate, sleep tracking and so forth.
Sport mode is for users looking to track their vitals, steps, and the duration of an activity session. Here you find accurate steps and running time using google map and your phone GPS.
My biggest problem with Cardio 2 is that it doesn’t do anything new. These features are something that other wearables in this price range. The Samsung Health or MI fit also offer food management or weight management features, which you don’t find here.
Tracking accuracy (buy or not to buy?)
For Tracking accuracy please check my full review video on my Youtube channel: Geekman.
The Lenovo Cardio 2 is decent fitness tracker with a price tag of Rs.1499. It has all the basic fitness-related features but this does not help the device stand out from its competition. The Mi band 3 and Samsung Galaxy fit E are really battered options with just 500 Rs extra.
