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 is...you 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!
