How to increase battery life of Mi Band 3?

Xiaomi has recently launched Mi Band 3 as its 3rd generation fitness band in India. It’s a much-improved fitness band as compared to all previous fitness bands by Xiaomi. Since nothing is perfect, how can Mi Band 3 be? If you’ve used the previous versions of Mi Bands, then you’d definitely know how good their battery life was. The first generation of Mi Band lasts for more than a month & similarly, the second generation of Mi Bands with the display can easily last for 20+ days. Xiaomi however, has claimed that their new Mi Band 3 with a much brighter OLED display can last about 20 days, but is failing at it. There are a bunch of Mi Band 3 users complaining about the poor battery life of Mi band 3. As per their claims, they are not even getting a full week of battery on their Mi Band 3.

Take a look at some of the Best Features of Mi Band 3!

Initially, the battery life of my Mi Band 3 wasn’t that good & even I was disappointed by their false claims. But after digging into settings, I was able to find what’s actually eating the battery life of Mi Band 3. And now I can get the claimed battery life on my Mi Band 3. I fully charged my Mi Band 3 on 3rd October & it’s 55 % left as of 14th October. So, I can easily get the claimed 20 days of battery life on my Mi Band 3. In this article, I will share all the settings that I have done to increase the battery life on my Mi Band 3 so that you can all get some benefit out of it.


1. Turn off continuous heart-rate monitoring:

Continuous Heart rate monitoring is the main culprit of this poor battery life. You can monitor your heart continuously with the Mi Band 3, at a set interval of time. This is a handy feature for those with inconsistent heart rate issues. But on the downside, it will consume way more battery every time your band triggers the HR sensor. By default, this feature is turned on & turning it off will increase your battery by a huge margin.

How to turn off Continuous Hear Rate monitoring?

  • Open the Mi Fit app & make sure that your Mi band 3 is properly synced.
  • Now on the ‘Profile‘ tab, tap on ‘Mi Band 3‘ under ‘My devices.
  • There find ‘Heart Rate Detection‘ & simply, turn it OFF.

2. Turn on Night Mode:

The recent update of the Mi Fit app includes the Night Mode feature. This feature dims the brightness of the display of your Mi Band 3 & lets you save some extra juice. And as the name suggests, it will automatically lower the screen brightness after sunset or as set by the user. You can also turn it on for the entire day, but it will possibly affect the sunlight legibility of the display.

How to turn on Night Mode?

  • Open the Mi Fit app & make sure that your Mi band 3 is properly synced.
  • Now on the ‘Profile‘ tab, tap on ‘Mi Band 3‘ under ‘My devices.’
  • There look for ‘Night Mode‘, inside ‘Night mode‘ options, you can either set it to ‘Turn on after sunset‘ or ‘Schedule turn-on time‘. Turn off after sunset will turn on the night mode after the sunset automatically. While for Schedule turn-on time, you’ll have to set a ‘Start time‘ & ‘End time‘ as per your preference. Setting both to 00:00 will enable Night more for the whole day.

3. Turn off App Alerts:

We can now see notification alerts on the Mi Band 3 & with a bigger screen, it allows you to show some content as well. Every time you will receive a notification, it will vibrate you to notify you about it. If you have added a certain app that receives notifications very frequently then you can definitely turn this option off to get more juice out of your Mi Band 3. I have completely disabled app alerts since I don’t need them at all.

How to turn off app alerts?

  • Open the Mi Fit app & make sure that your Mi band 3 is properly synced.
  • Now on the ‘Profile‘ tab, tap on ‘Mi Band 3‘ under ‘My devices.’
  • Look for the app alert option, open it & turn off app alerts completely. If you don’t want to turn it off completely, then remove apps that are pushing frequent notifications.
