Virtual Private Network, or VPN for short, is a widely-used way to keep your online activities, sensitive data, and real-life identity safe from prying eyes. Furthermore, with this security solution, you can virtually travel all over the world and access any content you like.

That sounds great! However, there are several slight issues you may face while using VPN applications. They are connection speed and battery charge. In this piece, we are going to review the second issue. To learn why VPN slows down your internet connection and how to fix that, follow this link.

So, does using a VPN drain the battery? We put our credible VPN solution to the test on an iPhone device to check it out. Handle tips on saving your battery life while using a VPN are included. Make sure to look through them!

Does VPN Drain iPhone Battery: VPN Unlimited Testing

We believe that testing is the best way to check out whether to use a VPN drain battery or not. To determine this, we take an iPhone with iOS 15 and the VPN Unlimited app - a reliable security solution that aims to protect and expand your internet access.

Our testing includes one's everyday online tasks:

  • Watching streaming videos
  • Using social media networks
  • Browsing the internet

Let’s take it step by step.


Streaming Hulu movies for 10 minutes with the enabled VPN solution drains the battery from 100% to 97%. Watching the local Hulu library during the same time also takes 3% of the battery.

Next, it is a turn of using social media networks. Starting battery life is 94%. After 10 minutes of scrolling Instagram feed without a VPN app, we get 93%. Now we turn on VPN Unlimited and use Instagram for the same 10 minutes. And the result guessed it...92%. There is a loss of 1% across both tests.

The last test we are going to take is browsing the internet. In this case, surfing the web with a VPN drops battery by 1% while browsing with a disabled VPN app doesn’t affect the battery.

Of course, this testing isn’t strict as lots of external factors can affect it: background refresh settings, constantly running apps, push notifications, incoming messages, and whatnot. However, you can be pretty sure that VPN doesn’t drain your battery a lot (seems like there is no difference or a very little one). So feel free to get started with our credible VPN app and do not worry about an accidentally dead smartphone!

Why Does VPN Drain Battery

The answer to this question is an obvious one. Implementing state-of-the-art, high-reliability, and proven encryption algorithms is an energy-intensive process.

As VPN Unlimited scrambles both the incoming and outgoing traffic of your device with the military-grade AES 256-bit encryption, a slight battery drain is normal. It should not be forgotten that rerouting traffic via virtual protocols also takes processing power and uses your battery.

However, a slight battery drain is a small price to pay for your online security and data privacy, isn’t it?

Tips to Preserve the Battery While Using VPN

Install VPN on your WiFi router

Don’t keep VPN enabled all the time

The easiest way to save your battery is to turn off the VPN when you aren’t using it. VPN Unlimited implements 2 options:

  • You can simply turn off your VPN connection.
  • Or you can use the Trusted Networks feature. This option allows you to add the WiFi networks you consider completely secure to the whitelist networks list. As a result, a VPN connection is going to be automatically disabled when your device connects to such WiFi hotspots.
