Most users complain about having to charge their wearable’s every day and Lenovo addresses this issue with an e-ink display, which can make its battery last for 7 days, even with Bluetooth and display always turned on. This also means, you don’t have to worry about sunlight visibility as the display will look better and brighter in day light. Yes, this one is water resistant IPX7 certified and will hold for 30 minutes when under 1 meter deep water.
You can mirror your smartphone notifications on the 1.43 Inch 230 ppi e-ink display and also monitor how many steps you have walked. There is no heart rate sensor or a microphone to take calls, but we don’t think that will be missed much. With curved metal body and leather steps, the VIBE Band looks stylish and can be bought for just $89. So, all that adds up to a pretty standard smartband, with its main highlight being the power efficient e-ink display.
