If you are the kind of user who uses their phone and plays games while charging, then this is also a reason which leads to battery draining issues.

Whenever you use or play games on your phone while charging, at that time your phone is drawing power and using the power at the same time. Although this phone has a 4,500 mAh battery and 67W fast charging, still users are using this phone while charging.

Wireless connections are also a big reason for battery draining issues in your phone. If you have ever noticed then, whenever you use Bluetooth and hotspots, battery consumption gets higher.

And every time when you use them for a long, the phone starts giving you a warning notification that “Your hotspot is enabled for a long time, please turn it off, it’s consuming battery a lot.”

Sometimes we forget to turn off the hotspot and Bluetooth after using them, and then some random device gets connected to your Bluetooth and hotspot.

And there are very possible that they can drive viruses toward your phone. So, please turn them off after using them. And please try to use them less.

5. Disable Location Service:

Location is also a reason that drains the battery. When you install any application, many of them need location service to set it up. And there is a lot of existing application in our which needs location service to finish a task.

Apps like matrimonial, food delivery apps, UPI apps, cab, VPN, Google Maps, and more. And after using them we forget to turn off the location, and it continues running in the background.

So, due to continuous use of location, the battery drains very fast. So, please turn it off after using it. And, don’t enable it when it’s not in use.

6. Use Dark Mode:

To save more battery and get extra backup you can use dark mode on your phone. Nowadays every smartphone comes with a dark mode. Dark mode will not only help you to save battery but also protects your phone from overheating and it also helps to protect your eyes.

When you start using dark mode, it will feel odd for some days. But, trust me once you start using dark mode, then there is no going back. You will addict to the dark mode.

7. Disable Unusual App Notifications:

Every task on our phone plays a different role in our phone in a positive or a negative way. Notifications are also like that. We receive a lot of notifications in a day on our phones. Notifications like app updates, brand sales, matrimonial, and all.

Push notifications drain the battery too, because as we know that it’s also a part of processing and activity. And to do any task it needs power.

If you have ever noticed then, whenever you enable the WIFI or mobile data, we receive too many notifications. And our phone starts lagging at that point and it increases the temperature of our phone and the resulting battery drains fast.

So, you need to turn off all the unnecessary notifications simply. So to turn off notifications follow these steps:

  • Open the settings app on your phone
  • Scroll down and tap on the Notifications & status bar
  • On that page, tap on Manage Notifications

So if you have any apps which is consuming battery very much then remove them. And if a particular app is very important and you use it daily in your daily routine, then you can find an alternative to that app or can use the lighter version of that app.

Apps like Facebook, take too much battery in your phone so either you can use Facebook in your browser on your phone or you can use the lighter version of Facebook. Which is called (Facebook Lite or “Lite”).

So, you can use it and can fix this issue easily.

9. Don’t Use Battery Saver Applications:

Oh! If you are still using battery-saving apps these days, then you are living in 2016’s time may be. And if you don’t know then battery saving is the biggest culprit and threat to your phone.

If you have installed any kind of battery-saving app on your phone, then please remove it sooner than later. Because battery-saving apps keep running in the background to save more battery.

So, even if your phone is locked or not operational that app also runs in the background and in a search of any virus to kill it.

So, it runs 24/7 in the background and also pushes different notifications also. And consumes battery. And if that battery-saving app is not well optimized, then it becomes more dangerous to your phone.

It become the best portal to drive viruses toward your phone and can infect your phone. So, please remove the battery-saving app from your phone if you have any.

10. Reduce Display Screen Timeout Time:

The display is a very big reason that consumes battery a lot. More usage of the display can consume more power. If you leave your phone after use without turning it off, then it consumes battery a lot.

Because if you set the screen timeout after a long time, then it automatically consumes more battery. So, if you want to get more battery backup, then you have to reduce the screen time on your phone.

Many users who set the timeout time longer than recommended, set the timeout from 10 minutes to 30 minutes. And some users disable the screen timeout to infinite. That means it will never turn off.

And if accidentally you don’t lock your screen then it stays on and it consumes the battery faster. And because of the AMOLED screen, this phone consumes more battery than any other type of screen.

So, simply set the timer to 15 seconds to 1 minute, and hardly set it to 2 minutes. It will save the battery. And this method will fix Xiaomi 12 battery draining issue.

11. Remove Unusual Apps:

There are a lot of apps on our phones we install, some of them are very useful and some we install to use once and we don’t use that again. And then we forget to remove them from our phones.

So, that app keeps running in the background and consuming storage, data, RAM, and all. And that consumes too much power. So, please remove that app from your phone.

12. background Running Apps & RAM consuming Apps:

Background running apps is also a big reason for battery draining issues in your phone. There must be some app that consumes background data, creates a cache, and takes RAM.

And because of background processing, we could not even identify why our phone is heating up and you get panic. So, identify which app is consuming more background data and close the.

And sometimes we forget to close some apps after using them and jump to another app. And the previous app runs in the background and stays in the RAM.

Then processing power has to process very fast and your phone gets overheated. Because of overheating your phone performs a task to cool down your phone and because of continuous processing power and battery drain very fast.

And this loop goes on, so please close apps after using them and then stop the app to consume data and other stuff to consume in the background.
