FAQs

What's the Fastest VPN for iPhone?

In my speed tests, Hotspot Shield (paid version) is the fastest VPN overall, with just a 1% slowdown across its entire server network.

Does a VPN Slow Down Your Internet Speed?

Based on my tests, on average a VPN will reduce your internet speed by 7% on nearby servers, and 16% on longer-distance connections.

This slowdown is caused by data being encrypted and being routed through a remote server before reaching its destination.

Do All VPNs Leak Data on iOS?

Yes, unfortunately all iOS VPN apps will leak some data. Since iOS version 13.4, some DNS queries from Apple services are sent outside the VPN tunnel.

Most of these non-VPN connections last only a few seconds, but some can last up to a few minutes.

While Apple is aware of this bug, the company has yet to implement a comprehensive fix.

Do iPhones Have a Built-In Free VPN?

While iPhones come with native support for VPNs, a free VPN isn’t included in your device.

There is a prominent VPN toggle in the Settings app, from which you can manually configure an IKEv2/IPsec and L2TP/IPsec connection.

Since no third-party app is required, this saves space. However, manual configuration doesn’t support OpenVPN or WireGuard, it doesn’t include a kill switch, and you’ll still need to subscribe to a VPN service.

In short, you’re better off installing a trusted VPN application from the App Store.

Does a VPN Use More Mobile Data?

You’ll use more data on your phone when a VPN is running. My research into VPN data usage revealed mobile data consumption increases between 4% and 20% when you use a VPN, depending on the VPN and protocol you use.

An extra 4% to 20% consumption may not sound like a lot, but over time it can add up quickly.

If you’re about to reach your data limit, or if you’re traveling abroad and paying roaming charges, consider switching to a lower-consumption VPN protocol like WireGuard or IKEv2, rather than using OpenVPN.
