Xiaomi Mi 4 Smart band

Xiaomi Mi 4Updated August 24, 2019: On the surface of it the Xiaomi Mi 4 looks like it’s predecessor, the Mi3, but it is NOTHING like it. The original was/is a fine, mono display smart band which my wife LOVES, but the Mi 4 is a full colour model while still retaining several days battery life (20 according to Xiaomi and I will go along with that, the band has hardly been off my wrist for 11-12 days now (other than when swimming in the sea or taking showers  – I’m convinced it is waterproof as claimed but I’d rather not push my luck – I love the unit too much) and is still showing 60% battery charge. Xiaomi have provided us a much needed watch face library and this smart band also supports various independent watch-face libraries. I love it.

Xiaomi Mi 4 bandDespite the manual coming entirely in Chinese, on opening the box, I noted a QR code inside the manual and scanned that with my Pocophone, which then loaded up the Mi Fit App. I initially let the band (or rather it’s detachable central module) charge for an hour or so before doing anything – just as well as all I got was Chinese output initially. Once Mi Fit was installed on my phone this was sorted automatically

I already have a MI account but signing up is easy. Once signed in, the band started to display in English – job done. No ECG or Oxygen levels in this model – indeed facilities are basic compared to some – but the quality is very good. As soon as the watch had charge in it, both the app and the firmware updated to the latest versions.

Ah but this is merely the beginning… read further on for more general information and the link at the end has the technical info – but most importantly – the Mi 4 supports custom watch faces both in the MIFit application and third party applications and sites…

Mi Band 4 Faces

If the many faces on the MiFit application are not enough for you, head on over to this site and check out the Mi Band 4 section or better – install the Amazfit app – I don’t have room here to show more than a small selection of faces…

My initial reaction to all of this was to say “well, yes but it isn’t that bright in sunlight, But it turns out that default initial brightness was only half way up and as soon as I discovered that, I turned it up to full and left it there. So you CAN see the faces in bright lighting. There will of course be a battery charge life trade-off but 11-12 days on I’m still impressed, see above.

You can get the bands in a range of colours and I have a few Caribbean versions though I keep reverting to black – call me old-fashioned. The watch handles sleep monitoring, alarms, reminders, pulse checking and sports.   You can play music stored on your phone. Bluetooth is v5.0 and the watch is waterproof to 5m – I HAVE actually deliberately tested it in the shower but I’m not brave enough to wear it in the sea.

At 29 Euros from Banggood (checked August 24, 2019)  the Mi4 is a bargain – here in Spain I recently bought an un-branded similar-looking band for 26 Euros, took it to our local fresh water pool and that was the end of it.  Recently accidentally leaving the Mi4 on in the same pool did absolutely no harm.

Charging is via a supplied cradle-type USB lead – easy and up to now, utterly reliable.

    1. Check out the link I gave – you have to wade through endless promo photos however. The actual MI site has even more info under SPECS – https://www.mi.com/global/mi-smart-band-4/specs/
      and there it ALSO clarifies that their claim for battery charge life is 20 days. I can see there all about:

      Alarm, proximity sensor, pre-set watch face, customizable watch face,
      lock screen, timer, stopwatch, phone alarm and notifications, incoming
      calls, message notifications, calendar notifications, app notifications,
      weather forecast, Find my phone, phone unlock, event notification,
      Night mode, Do not disturb mode (works even without phone), music
      controls on band, Bluetooth broadcasting, battery level display, different
      ways to wear, OTA updates

      Is that enough info? Neither site mentions that there is a massive AMAZFIT site and others with even more watchfaces. You can never have too many watchfaces,

  1. Thank-you Peter. Very generous answer – I imagine you’re basking in a glorious Spanish evening with a bit of time on your hands! Lucky you. Think I’ll get one. Cheers from drizzly London.

    1. from what i’ve seen in various youtube videos, you can manage it via both the mi fit app, and the amazfit one, choose your preferred one… and yes, you have full notification, phone caller id, etc 🙂
