5 Best Battery-Efficient VPNs for Your Mobile Device

If you’ve ever felt your phone getting warmer and its battery life plummeting when using a VPN, you’re not alone.

Many VPN users have experienced this phenomenon, which often raises the question, “Does using a VPN drain your battery?“.

The simple answer is some VPNs do have a reputation for draining batteries faster than a toddler can dismantle a perfectly organized toy shelf.

However, not all VPNs are created equal. Some, like NordVPN, ProtonVPN, ExpressVPN, Hide.ME, and SurfShark, have made strides in becoming more energy-efficient, causing less strain on your device’s battery life.

This blog post delves into the world of easier VPNs on your device’s battery, helping you maintain your online privacy without having to carry around a charger everywhere you go.

What Makes a VPN Drain Battery?

A VPN, by nature, adds an extra step in the route your data takes from your device to the server.

This data encryption and decryption process requires more computing power, leading to increased power consumption and, subsequently, battery drain.

Furthermore, keeping a constant VPN connection can result in additional battery usage, particularly when your device struggles to maintain a stable connection in a low-signal environment.

However, it’s not all doom and gloom. Not all VPNs are notorious battery guzzlers. Certain VPNs, like those we’ll discuss later, are designed to be battery-friendly and energy-efficient.

They accomplish this through a combination of optimized coding, lightweight apps, and smart connection protocols that minimize their power requirements.

Other factors like the type of device, its age, background apps, and even the strength of your internet connection can also impact battery life.

What Are The VPNs That Don’t Drain Your Mobile Battery

We’ve compiled a list of the top 5 VPNs known for their battery-friendly nature.

1. NordVPN

NordVPN has etched its name as one of the most trusted VPN providers in the world, partly due to its superior security features, fast connection speeds, and of course, its battery-friendly operation.

One of the highlights of NordVPN is its lightweight app design. Its developers have managed to pack a plethora of features into the software without turning it into a power-hungry beast.

NordVPN has a well-optimized app that does not heavily rely on your device’s processor, thereby conserving battery power.

This efficiency doesn’t compromise its functionality or security, as NordVPN employs advanced encryption standards to secure your data.

The app also comes with an automatic kill switch that immediately stops all internet traffic if the VPN connection drops.

This feature protects your privacy and helps in power conservation as it minimizes unnecessary data transmission.

NordVPN’s Quick Connect feature ensures that your device connects to the fastest server available, reducing the time and power spent establishing a connection.

This smart algorithm selects the best server based on location, load, and other parameters, further adding to the VPN’s energy efficiency.

NordVPN has over 5400 servers spread across 59 countries, ensuring a stable and fast connection, which is vital for power conservation.

Remember, a slow or unstable connection can cause your device to work harder to maintain the connection, leading to faster battery drain.

2. ProtonVPN

ProtonVPN, founded by the same team behind the highly secure ProtonMail, takes a no-compromise approach to privacy and security.

Despite the robust security measures, ProtonVPN manages to stay incredibly energy-efficient, thanks to the well-optimized nature of its app.

The VPN service implements advanced security features such as strong encryption, perfect forward secrecy, and an automatic kill switch.

The latter ensures your privacy and aids in power conservation by preventing unnecessary data transmission when the VPN connection drops.

ProtonVPN also offers the option to use lower encryption levels (AES-128) for faster speeds and less CPU (and consequently battery) usage.

However, this does not compromise your security, as AES-128 is still considered extremely secure.

Another standout feature is its Secure Core network. This routes your traffic through multiple servers before leaving ProtonVPN’s network, providing an extra layer of security.

While this feature may require a bit more energy than a standard VPN connection, it is well-optimized to minimize battery drain.

3. ExpressVPN

With ExpressVPN, it’s all about balance. This VPN successfully combines high-speed connections, robust security measures, and battery-friendly operation.

Its app is designed to be lightweight and efficient, thereby minimizing battery drain.

The security standards of ExpressVPN are top-notch, employing strong 256-bit AES encryption, DNS/IPv6 leak protection, and an automatic kill switch.

The latter feature is especially useful for preserving battery life by preventing unnecessary data transmission in case of VPN disconnection.

ExpressVPN uses a proprietary technology called Lightway designed to improve VPN speed, reliability, and connection times, while also being light on battery usage.

It is touted as more efficient than traditional VPN protocols, consuming less battery and offering faster speeds.

The app’s user interface is straightforward and intuitive, allowing users to establish connections quickly with the least amount of power and time.

The Smart Location feature automatically selects the optimal server based on your location, further enhancing the VPN’s energy efficiency.

The expansive network of over 3000 servers across 94 countries ensures stable and high-speed connections, which are crucial for conserving battery life.

4. Hide.ME

Hide.ME is a VPN service that stands out for its strong commitment to privacy, high-speed connections, and efficient power usage.

One notable feature of Hide.ME is the sleek design of its app, which is optimized for energy efficiency. This VPN manages to offer a robust set of features while minimizing battery drain.

When it comes to security, Hide.ME utilizes strong 256-bit AES encryption, IP leak protection, and an automatic kill switch that helps conserve battery power by preventing unnecessary data transmission in case of a VPN disconnect.

The VPN service also offers multiple VPN protocols, including IKEv2 and WireGuard, known for their speed and efficiency.

WireGuard, in particular, has been praised for its streamlined codebase and performance, making it less resource-intensive and thus gentler on your battery.

Hide.ME’s app interface is straightforward and user-friendly, allowing you to connect to the best server quickly and easily.

The less time and power spent on setup and server selection, the better for your device’s battery life.

The network of over 1800 servers in 72 locations worldwide ensures that you can always find a stable and fast connection.

This is essential, as an unstable connection can cause your device to work harder, rapidly depleting battery life.

5. SurfShark

SurfShark’s app is designed with energy efficiency in mind. Its lightweight nature ensures it doesn’t excessively drain your device’s battery while providing powerful features.

When it comes to security, SurfShark doesn’t hold back. It offers top-tier 256-bit AES encryption, an automatic kill switch, and private DNS on each server.

This kill switch feature is particularly useful for saving battery life, as it prevents unnecessary data transmission if the VPN connection is lost.

One standout feature is the use of the WireGuard protocol. Known for its streamlined code and performance, WireGuard consumes fewer resources, making it gentler on your battery than other VPN protocols.

SurfShark’s CleanWeb feature, which blocks ads, trackers, and malware, can also help conserve power. By eliminating unnecessary ads, your device processes fewer data, saving both bandwidth and battery life.

The user interface of the SurfShark app is simple and easy to navigate. It allows you to establish a secure VPN connection quickly, reducing the time and energy spent on setup.

Furthermore, SurfShark boasts over 3200 servers in 65 countries, providing a stable and speedy connection.

A stable connection is crucial for battery conservation, as a poor connection can cause your device to work harder, leading to quicker battery drain.
