However, recently, for Samsung Galaxy S22/S22+, and S22 Ultra users, Wi-Fi calling has become a threat to their devices’ battery life. For these devices, Wi-Fi calling drains battery life and that gives this convenience a little of a hassle.

If you are a Samsung Galaxy S22/S22+, or Samsung Galaxy S22 Ultra user who experiences the same problem, this article is fit for you to read.

Why WiFi Calling Drains the Battery on Samsung Galaxy S22 Devices?

Before we get into how to fix your Galaxy S22 battery draining issue while in a Wi-Fi call, I think it is important for you to know about this problem and its possible causes so that you can avoid or fix them in the future.

There can be more reasons why Wi-Fi calling drains the battery of your Samsung Galaxy S22 smartphone.

Below are the most reported and most identified reasons behind it.

Cause 01 – Weak Wi-Fi Signals and High CPU Usage

If your Wi-Fi router or the extender is placed far from your Galaxy S22 device, then because of the poor signal, your smartphone will try to increase the receiver strength to get more signal, thus, this can lead to battery draining and shortened battery lifespan.

Cause 02 – Poor Cellular Signals

Even though your Wi-Fi router is placed near your Galaxy S22 smartphone, if the Wi-Fi router does not get enough signals when you are in a call, the device will automatically try to get the maximum signals out from your Wi-Fi router.

Although this is not always true for every Wi-Fi router, there are some routers (especially portable ones) that can decrease Wi-Fi strength to save battery power. On such occasions, this could lead to a drain of the battery if you are in a Wi-Fi call.

Cause 03 – Wi-Fi Calling Creates a Tunnel

When you place a Wi-Fi call, it will automatically establish an IPSec tunnel between your smartphone and the mobile network. To keep the call, the tunnel uses the device’s battery and its CPU power which can eventually drain your Galaxy S22’s battery.

How to Fix Samsung Galaxy S22 Battery Draining While Wi-Fi Calling

Now, you should have a clear understanding of what causes the Wi-Fi calling to drain the battery of your Galaxy S22 smartphone.

You want to fix it, right? No worries! Let’s go to the solutions to save your S22’s battery life!

Fix 01 – Use 2.4GHz Network

There are two (2) types of network frequencies in Wi-Fi networks, one is 2.4GHz and the other is 5GHz. 5GHz network frequency gives more speed but less coverage. On the other hand, 2.4GHz gives more coverage but less speed.

So, if your router uses 5GHz to broadcast the signal, it can drain your galaxy S22 device’s battery more frequently that is because the farther you go, the more power will be used to keep the connection. Therefore, you can try to switch from 5GHz to 2.4GHz in your Wi-Fi router’s settings.

Log into your Wi-Fi router’s settings page (using your browser, please refer to your router’s documentation if you don’t know).
Go to Settings, then Network settings.
Then go to Advanced settings and from there you can switch to 2.4GHz mode.

change working band to 2.4GHz — Note: User interface varies from wi-fi routers

Fix 02 – Turn on Airplane Mode

Even if you are connected to Wi-Fi, it does not mean your Galaxy S22 smartphone does not look for cellular signals anymore. The mobile wants to keep the connection so it will consistently work on getting signals from an appropriate cellular tower. This can potentially drain the battery and will also reduce the battery life of your Galaxy S22.

In this scenario, the best thing you can do is to turn your device to airplane mode so the cellular network will be turned off and you will be left with the Wi-Fi connection alone. This way, you can increase the battery life and stop battery draining in your Samsung S22 device.

Turn on Airplane mode

Fix 03 – Use the Wifi Calling in a Close Range/Use a Repeater

If you have read this guide from the beginning, now you know that being far from the Wi-Fi router will eat up your battery.

Therefore, to avoid this, you can stay or keep your Galaxy S22 within close range of your Wi-Fi router.

If you cannot do this, you can use a Wi-Fi repeater, which repeats the Wi-Fi signal to an extended area. In this way, you can use your S22 device far from the router without draining the battery power when Wi-Fi calling.

Fix 04 – Check for System Updates

Keeping your Galaxy S22 device up-to-date is a good habit for you to use it without having problems.

Firmware/Software updates include various bug fixes and performance improvements, tweaking the device’s hardware for best performance and better battery life.

Tip: See our Samsung Galaxy S22 software update tracker

If you haven’t checked for updates for your S22 device, then it is time to do so.

Head over to Settings.
Tap on Software update.

Conclusion

Did the above fixes work for you? Now, you can freely talk to your loved ones any time you want without the need to worry about your device’s battery life.
