Does VPN Use More Battery and Drain Your Phone Faster?
Battery life is likely one of your top concerns if you depend on your Android or iOS devices. Even as smartphones’ batteries become larger and more powerful, battery consumption remains a problem. The majority of us still do whatever we can to get through the day, or at the very least from a charger to charger, without our phones dying. Larger screens and more power-hungry applications begin to deplete battery life and drain the battery on our smartphones as battery capacity increases.
Protection is another major concern for Android and iOS users. Using a VPN is one of the easiest ways to keep your details safe when using your phone. Does VPN, on the other hand, affect battery consumption? If so, what’s the reasoning behind it? What is the impact of using a VPN on battery life? Finally, how do you extend the life of your battery by using a VPN?
Does VPN Drain the Battery on Your Phone?
It certainly does. The exact amount is determined by some variables. Using a VPN on your Android or iOS computer will use anywhere from 5% to 15% more battery than not using one. Keep in mind that any app you have open on your phone will use battery power, particularly those that run in the background.
Why Does VPN Drain Battery?
- Encryption – All data sent to and received from your VPN is encrypted, and it must be decrypted before it can be used. Encryption and decryption also require computing power, which is consumed by the battery. Also, bear in mind that the higher the encryption level and the safer it is, the higher the battery usage. The OpenVPN protocol uses the most computing power but is nearly unbreakable thanks to AES-256 bit encryption.
- Non-Optimized CPUs – Hardware-accelerated AES encryption is available on certain iOS computers. This not only accelerates the operation but also saves battery life by avoiding the inefficient method of encrypting on the main CPU. Devices that don’t have this feature can have shorter battery life.
- Background Use –, even when you aren’t sending or receiving data. The app keeps a live link to the VPN server so that it is ready to use when you need it. This necessitates the use of both your CPU and your phone’s cell radio chip. When these two factors are combined, they can affect the battery life of your Android or iOS device.
- Poor Signal Strength – your WiFi or mobile network tower will burn the battery even if you don’t have a VPN link active. To communicate with the weak signal, your system will increase the power. For a VPN, this can be much worse. Since most VPNs function to maintain the link, higher power consumption can persist even if you aren’t using data.
How Much Battery Does VPN Use?
When you use a VPN on your computer, you should expect a 5-15 percent improvement in battery usage. VPN use influences battery consumption in a variety of ways. The phone you use, the service you use, and your proximity to WiFi or a cell tower will all affect your results. Your battery usage could be on the low end of the spectrum if you’re using a weaker encryption standard, have a phone with hardware acceleration for encryption, have regular access to a strong data signal, and use the right VPN. There are also several ways to lessen the impact of a VPN on battery life.
How to save battery with a VPN?
- Don’t depend on a VPN all of the time – When you’re not using your VPN on your iOS or Android device, the simplest way to save battery life is to turn it off. This has two layers to it. You could start by simply turning off the VPN when you aren’t using your phone. This would prevent it from running in the background to maintain the connection. Second, if you’re on a secure network and don’t mind your ISP knowing what you’re doing, you can turn it off.
- How to Set Up a VPN on a Router – You can turn off the VPN on your phone when using it at home or work and still have the same degree of privacy and security. Install the VPN on your router and you’re ready to go. This will safeguard not only your cell but all of your other devices as well. You can switch off the VPN on your phone once you can connect to your own router. When you need to use your mobile data, just remember to turn it back on.
- Ensure that your VPN settings are correct – The VPN you’re using now may have a battery saver mode or other power-saving features. Before you turn them on, make sure you understand what they do so you can be confident that your link will be safe when you need it.
- Use a VPN that consumes little battery power – Not all VPNs are created equal, particularly when it comes to battery life. As VPNs have grown in popularity among mobile users, developers are searching for the most efficient ways to minimize power consumption. If keeping your phone battery charged is important to you, look for new features such as battery savers and different modes for different connections in possible VPNs.
Apps that use a VPN do not use more battery than most apps. They normally increase your phone’s battery consumption by 5% to 15%. The amount of data consumed is determined by the phone’s type, signal quality, encryption settings, and system efficiency. Using a VPN that is tailored for your phone or installing a VPN on a router is one way to save energy.
