As we increasingly rely on our smartphones to stay connected with the world, one feature that has become ubiquitous is Wi-Fi calling. The ability to make and receive calls over a Wi-Fi network has revolutionized the way we communicate, especially in areas with poor cellular coverage. However, with this convenience comes a nagging concern: does Wi-Fi calling drain battery? In this article, we’ll delve into the world of Wi-Fi calling and explore the impact it has on your device’s battery life.
The Basics of Wi-Fi Calling
Before we dive into the battery drain aspect, let’s quickly cover the basics of Wi-Fi calling. Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a technology that allows your phone to make and receive calls over a Wi-Fi network. This feature is especially useful in areas with weak or no cellular signal, such as basements, rural areas, or even abroad.
Wi-Fi calling works by using the internet connection on your phone to connect to a Wi-Fi network, and then routing your calls through the internet to the intended recipient. This process is often referred to as Voice over Internet Protocol (VoIP). The technology is supported by most smartphones and many carriers, making it a convenient solution for staying connected.
How Wi-Fi Calling Affects Battery Life
Now, let’s get to the meat of the matter: does Wi-Fi calling drain battery? The short answer is yes, it can. However, the extent of the drain depends on several factors, which we’ll explore in detail.
Radio Frequency (RF) and Power Consumption
When your phone is connected to a Wi-Fi network, it uses radio frequency (RF) signals to communicate with the network. RF signals require power to transmit and receive data, which can lead to increased battery consumption. The power consumption is directly proportional to the strength of the RF signal. The stronger the signal, the more power it consumes.
In the case of Wi-Fi calling, the RF signal is used to maintain the connection with the Wi-Fi network, which can result in increased power consumption. This is especially true when you’re making or receiving calls, as the phone needs to constantly transmit and receive data to maintain the call quality.
Processing Power and CPU Usage
In addition to RF signals, Wi-Fi calling also requires processing power to handle the VoIP protocols and encode/decode audio signals. This processing power is provided by the phone’s central processing unit (CPU), which consumes battery power.
When your phone is engaged in a Wi-Fi call, the CPU works harder to process the audio signals, manage the call, and maintain the Wi-Fi connection. This increased CPU usage can lead to higher battery consumption, especially if your phone is already running low on power.
Screen Brightness and Display Power Consumption
Another factor that contributes to battery drain during Wi-Fi calling is screen brightness. When you’re on a call, your phone’s screen remains active, consuming power to display the call interface, contacts, and other information. The brighter the screen, the more power it consumes.
Additionally, the phone’s display also consumes power to display the Wi-Fi calling interface, which can be resource-intensive. This display power consumption can add up over time, contributing to the overall battery drain.
Factors That Influence Wi-Fi Calling Battery Drain
While Wi-Fi calling can drain battery, the extent of the drain depends on several factors. Here are some of the key factors that influence Wi-Fi calling battery drain:

The type of phone you use, its hardware specifications, and software version can all impact Wi-Fi calling battery drain. For example, newer phones with more efficient processors and radios tend to consume less power during Wi-Fi calling. Similarly, phones with optimized software for Wi-Fi calling can reduce battery drain.
Wi-Fi Network Strength and Quality
The strength and quality of the Wi-Fi network you’re connected to can also impact battery drain. A strong and stable Wi-Fi signal requires less power to maintain, whereas a weak signal can cause the phone to work harder to maintain the connection, resulting in increased power consumption.
Call Duration and Frequency
The length and frequency of your Wi-Fi calls can also impact battery drain. Longer calls or frequent calls can lead to increased power consumption, especially if you’re using your phone’s speakerphone or video calling features.
Background App Usage and Multitasking
If you’re using other apps in the background while making a Wi-Fi call, it can increase battery drain. This is because these apps continue to consume power and resources, even when you’re on a call.
Tips to Minimize Wi-Fi Calling Battery Drain
While Wi-Fi calling can drain battery, there are ways to minimize the impact. Here are some tips to help you reduce Wi-Fi calling battery drain:
Use a Power-Efficient Phone
Choose a phone with power-efficient hardware and software. Look for phones with optimized Wi-Fi calling capabilities and features like low-power modes.

What is Wi-Fi calling and how does it work?
Wi-Fi calling, also known as Voice over Wi-Fi (VoWi-Fi), is a feature that allows you to make and receive phone calls using a Wi-Fi network instead of the traditional cellular network. This feature is especially useful in areas with weak or no cellular coverage. When Wi-Fi calling is enabled, your phone automatically switches to a nearby Wi-Fi network to make and receive calls.
Wi-Fi calling works by using the internet protocol (IP) to transmit voice signals over the Wi-Fi network. This allows your phone to connect to a Wi-Fi router, which then connects to the internet, and ultimately to the recipient’s phone. The call quality is often superior to traditional cellular calls, and it can also help reduce dropped calls and improve overall call reliability.
Is Wi-Fi calling the same as VoLTE?
No, Wi-Fi calling and VoLTE (Voice over LTE) are not the same, although they share some similarities.
