Xiaomi Mi Smart Band 4 unveiled and it could be a Fitbit Charge killer

Xiaomi’s latest budget-friendly activity tracker has been launched, and it boasts a host of all-new features to rival what FitBit has to offer.

The Xiaomi Mi Smart Band 4 will have a 0.95-inch colour AMOLED display, voice assistant, and water resistance up to 50 metres, making it a considerable upgrade to its very popular predecessor. The wearable will go on sale in Europe on June 26, starting from €35 (~£31/$40) — the UK launch date and price hasn’t yet been confirmed. Packing all these impressive features at such a low price raises the question of whether Xiaomi will finally knock Fitbit off its perch.

In our review of the Xiaomi Mi Band 3, we described it as a bare-bones fitness tracker and even given its budget price (£27/~$35) we were not impressed by its highly inaccurate heart rate monitor and very basic sleep tracking. However the battery life, build quality, and water-resistance were somewhat redeeming features. We’ll have to see significant improvements in the performance of the Mi Smart Band 4 before we can recommend it.

By contrast, the rival Fitbit Charge 3 scored 4.5 stars out of 5 in our in-depth review and received praise for the quality of its companion app, large sharp display, and strong battery life. At £120 ($120), it’s much more expensive than the Mi Band 3 — but in this case, you get what you pay for. Remember to check out our review of the Mi Smart Band 4 after to launch to see if it really can offer a cut-price but reliable alternative to Fitbit.
