In today’s world, cyberthreats are more prominent than ever and people are constantly looking for a way to enhance their privacy and security. A VPN has become a very popular way to keep your data secure when browsing online. A VPN is a great tool to promote security and privacy; however, there are some drawbacks to using a VPN, such as your battery life draining quicker.
What Is A VPN, And What Does It Do?
A VPN (Virtual Private Network) is a tool that helps promote security and privacy for online activities. This is done by securing your entire connection. When you connect to a VPN, your connection is rerouted through a VPN server that masks your IP address. Additionally, your data is routed through an encrypted tunnel that keeps your data safe from prying eyes.

Why Do VPNs Affect Your Battery Life?
The VPN processes are usually the reason why your battery life is draining. The primary reasons are:
Encryption And Decryption
A VPN encrypts your data when it is routed through the encrypted tunnel. This means that an encryption key is created to encrypt and decrypt data. These protocols are usually OpenVPN or WireGuard, and this takes a lot of computational strength. Similarly, strong encryption standards like AES-256 demand more processing power, which can drain your battery.
Maintenance
A VPN keeps a steady link to a remote server, which means it has to constantly exchange data to stay stable, and this drains power.
Background Activity
VPN apps run in the background since they are consistently monitoring connections and also reconnecting when a signal is dropped. This background activity uses a lot of power.
Server Distance
When you connect to a server that is located on the other side of the world, the distance will require increased latency and data transfer demands. This will drain your battery.
Factors Influencing Battery Drain
Not all VPNs affect your battery life in the same way. These factors determine how much your battery will be drained:
- VPN Protocol: Protocols such as WireGuard are designed to be lightweight and efficient, especially for mobile devices, consuming less power compared to bulkier options like OpenVPN. For example, WireGuard boasts a smaller codebase, which helps to minimise computational demands.
- Device Hardware: Some of the newer smartphones have energy-efficient chips that can handle the VPN battery usage much better than older devices.
- App Quality: Some VPN apps such as Surfshark and NordVPN are optimised in a way to reduce battery drain.
- Usage Pattern: Some actions like streaming or gaming do require more data, which means that more processing power will be used, and this will drain your battery quicker.

Tips To Reduce Battery Drain When Using A VPN
There are a few things you can do to reduce battery drain when using a VPN:
Choose An Efficient Protocol
Most VPNs allow you to switch protocols in their settings. You should choose something like WireGuard, which is designed to consume less power.
Choose Closer Servers
Closer servers will not require so much latency and data transfer demands, which will help to reduce the amount of battery life that is drained.
Split Tunneling
Some VPNs offer split tunnelling. This is a method where you can choose to only route specific things through a VPN, thus reducing the workload of the VPN and minimising battery drain.
Only Switch The VPN On When Needed
When using a trusted Wi-Fi network, it is recommended to switch your VPN off.
Optimise Device Settings
To save battery life, try lowering your screen brightness, turning off background app refresh for apps you don’t really need, and switching on low-power mode. These simple tweaks can help ease the strain on your battery, giving you more juice for your VPN activities.
Choose A Good VPN Provider
When it comes to VPNs, premium options really put their money where their mouth is, investing in top-notch apps and solid infrastructure. On the other hand, free VPNs might seem appealing, but they often come with annoying ads or clunky coding that can really drain your battery.
Update Your VPN App
Developers are always rolling out updates to enhance performance and tackle any pesky bugs. Make sure your VPN app is updated so you can take advantage of those battery-saving tweaks!
Will VPNs And Battery Life Be A Problem?
VPNs do drain battery because of processes such as encryption, decryption, maintenance, server location, and background activity. By selecting efficient protocols, fine-tuning your settings, and opting for trusted VPN providers, you can greatly minimise battery drain while still keeping your security strong. With the right strategy, you can reap the rewards of a VPN while keeping your device’s battery life intact, making sure you stay secure and convenient while on the move.
While it’s true that using a VPN can drain your battery a bit more, many people find that the added security is totally worth it, especially when you’re on public Wi-Fi or dealing with sensitive information.
