10 Tips to Solve Battery Drain Issue on MIUI 9 and Redmi Devices

Xiaomi released the MIUI 9 update last year, which is available for all old Redmi phones like Redmi Note 4 and Redmi 4. All new phones now come with pre-installed MIUI 9.

If you’re experiencing battery drain on your phone, don’t worry. These 10 tips and fixes can help resolve the problem.

1. Update Your Phone and All Apps

To solve the battery drain issue on your MIUI 9 Redmi device, first check for software updates.

To update your device, go to Settings and tap About phone, then select System update. If an update is available, proceed with the installation. Additionally, make sure to update all installed apps from the Google Play Store.

One way to resolve battery drain is by clearing device cache. Cache is temporary data that apps download to avoid downloading it every time. This is different from app data.

Clearing cache can address various device issues, including battery drain. Although the option to clear cache was removed in Oreo, it still exists in MIUI 9 and can help fix battery drain.

To clear cache on your device, follow these steps:

Step 1: Open Settings on your phone and tap Storage.

Step 2: Under Storage, wait for your device to finish calculating space and data. Tap on the Cached data option. You will get a notification asking you to confirm clearing cached data for all apps. Tap OK.

3. Find the Culprit Third-party App

Many times, MIUI software is not solely responsible for battery drain. The issue could also be caused by a third-party app.

To identify the app responsible for battery drain on MIUI 9, follow these steps:

Step 1: Open Settings on your phone and tap Battery.

Step 2: Tap on the Power option, then Battery use.

Step 3: You will find all the apps using your battery in decreasing order of usage. The app draining most of your battery juice will be on top. If you find a rarely used app on top, that app is responsible for battery drain.

We suggest clearing the cache and app data for that app from the individual Storage settings (Settings > Installed apps > App > Storage > Clear cache and Clear data). If that doesn’t resolve the issue, you could also try uninstalling the app temporarily.

4. Uninstall Rarely Used Apps

Rarely used apps can affect your phone’s battery. Check your Redmi device for installed apps and uninstall those you rarely use.

To uninstall an app, hold the app icon on the home screen. A delete icon will appear at the top. Drag the app icon to uninstall it.

5. Disable Wake Lock Screen for Notifications

Every notification lights up the lock screen, which can drain your phone’s battery. Turn off this feature to save battery.

To make your phone wake the lock screen for notifications, open Settings and disable the Wake lock screen for notifications toggle.

Most of the time, connectivity features like Bluetooth, NFC, and GPS are unknowingly enabled on our devices. These drain a lot of battery. To save battery, it’s better to manage and turn off these features when not in use. They can usually be turned off in the Quick Settings. Alternatively, you can go to the Bluetooth option under Settings to turn it off, or open Settings, tap More, and turn off NFC.

To turn off GPS or location, open Settings and go to Google. Tap on the Location option and disable Access to my location.

7. Turn Off Scanning

Android devices, including Redmi devices, have a feature called Wi-Fi Scanning. This feature scans for networks constantly, even when Wi-Fi is off, which drains the battery. To turn it off, go to Settings, tap Wi-Fi, select Advanced settings, and disable the Scanning always available option.

8. Turn Off Automatic Brightness

Most Android smartphones have automatic brightness turned on by default. However, this setting can affect battery life, so it’s a good idea to adjust the brightness as needed.

To turn off automatic brightness, follow these steps:

1. Open device Settings and select Display.

Step 2: Tap Brightness level and disable toggle Automatic brightness.

Increasing battery life can be achieved by reducing screen timeout. The longer the screen is on, the more battery it uses. Therefore, we recommend setting the sleep time to either 30 seconds or 1 minute.

To change Sleep time on your MIUI device, go to Settings, tap Lock screen & password, then choose your preferred time.

10. Hard Reset Your Device

If none of the above-mentioned fixes solve the battery drain issue, it’s time to go the hard way. You would have to format your phone. First, take a backup of your device. Then follow these steps to format your device:

Step 1: Open Settings on your phone and tap Additional settings. Scroll down and hit Backup & reset.

Step 2: Under Backup & reset, tap Factory data reset. Then tap the Reset phone option at the bottom.

Enjoy.
