How to improve the battery life of your Xiaomi Phone running MIUI 12

Today almost every Xiaomi Smartphone comes with a Mammoth battery pack, even the latest one like Redmi Note 10. When Xiaomi phone is new, they tend to give good battery backup even in heavy or moderate use.

After the year, the problems with battery draining start to arise. The battery life of the Xiaomi phone starts decreasing day-by-day.

Here’s How to save the battery life of Xiaomi Smartphone in MIUI 12

Use Static Wallpaper

Xiaomi Static Wallpaper

One of the best new features of the MIUI 12 is those dynamic Super Wallpapers which are compatible with many Xiaomi phones and they look outstanding on the Xiaomi phone. Like all the animated wallpapers installed on any mobile, they consume much more battery than any other static wallpaper, so we encourage you to disable it and replace them with Static wallpaper.

BONUS: Use Dark Static Wallpaper as it consumes significantly less battery.

How To Set Static Wallpaper

Go to Settings > Wallpaper.

Here you will see the options to change wallpapers.

Simply tap on “Change” and select any static wallpaper that you wish to set, and click on “Apply’.

Disable Auto-Brightness

Auto brightness features automatically set screen brightness according to the daylight and low light condition, but it consumes a lot of battery juice. At first, it looks quite an odd thing to change it, but with Auto Brightness off, you can save up to 10% an hour of battery Juice.

BONUS: Adjust the brightness level manually to 50% or 30%, so it remains bright enough to read.

Disable/Uninstall Digital Wellbeing

Digital Wellbeing

Digital Wellbeing is the biggest reason for the battery drainage in MIUI. Digital Wellbeing helps you understand your phone usage better, lets you pause distracting apps, limits usage, visuals detailing, and how many notifications you receive. To perform all this task, it continuously runs in the background and collects data.

Hence, the app generates a lot of unwanted background activity, costing bandwidth and consume a lot of battery. By Disabling or Uninstalling, you can save a lot of battery and also get snappier MIUI 12. The user claimed by Disabling Digital Wellbeing, their battery improved, adding 1h SOT.

How to Uninstall Digital Wellbeing

Go to Settings > System App.

Search for Digital Wellbeing and open it.

Tap on “Disable” or “Uninstall” the choice depends upon a different Xiaomi phone.

Disable MIUI Optimization

MIUI Optimization

Disabling MIUI optimization is another option to Juice up your MIUI 12 battery Life. When you disable MIUI optimization, it reverts to stock android system management. It removes MIUI stylings from many MIUI integrated systems or apps, making them the same as in-stock android. Hence, it makes MIUI lighter and boosts up the battery life.

How to Disable it:

Go to Settings>Additional Settings>Developer Options> Turn off MIUI optimization

How to Find/Turn on Developer option, then follow this Youtube guide.           

Turn off Data Synchronization

The Xiaomi smartphone automatically synchronizes user data with the Google Account and consumes more data and battery consumption. By default, this feature is enabled on your Xiaomi Smartphone. However, it is important for apps like an email, but turn it off when not needed.

Open Settings>Account and Sync.

And Turn off.

Turn off system notifications.

MIUI 12 Battery Save

Notification is always an important part of an app in a smartphone as it keeps you up-to-date. The mobile phone status bar often receives some application push messages that are not important or related to Marketing or ads. These messages will automatically run in the background as long as you do not click to delete.

You can close some infrequently used applications notification, saving the phone’s power consumption and also preventing the phone from freezing.

How to Disable Notification:

Open Settings>Notification and Status Bar

Find Notification Management

Close unnecessary apps that are not commonly used.

Disable Playstore Auto-Update

Google has turned on the Auto-update option for apps over wifi in the Google Playstore by default. Whenever Google Playstore finds that you are connected to wifi, it starts updating all the apps in the background without any prior notification.

It drains not only your Battery life but also bandwidth. You can go to the play store to change the setting to ‘Do not auto-update apps’ This is the best way to save your battery life.

Deleting unwanted Apps

Do you like to fill up your working table with unnecessary and unwanted things, which in the end take up huge space? I guess No, then why your smartphone be any different? There are some apps on your smartphone which you haven’t used in months on your Redmi Note 8 or any other Xiaomi Phone.

These apps are huge storage space drainers as well as battery drainers. Only keep those apps that you use at least a week or monthly on your phone. Reduce the number of video players and music players to one. For Ex – MX Player is the one, Google Music, etc. Stop installing multiple kinds of weather and news apps as they are heavy battery drainer.

Reduce system animations

It means that only these programs can consume cell phone resources. If you have missed an application, click on “Add” and select only what is important.

Turn Off GPS/Location

The GPS/Location is one of the features that draw a huge amount of battery juice. This feature can be turned on with any app, especially Geolocation apps like – Uber, Zomoto, Urban Clapper etc.
