[iPhone] Does using a VPN significantly decrease battery life?

Quote:

If your VPN setup keeps the data connection active in the background then yes it destroys battery life. If you turn the VPN on and off as needed its nothing significant. There's also an official OpenVPN Connect app now too.

Thanks blakkout. Yeah, I've just been leaving it on. I set it up last night but didn't really look at the battery usage. After sitting here at my desk for about 30 minutes now, it does appear to be using the batter a little faster than normal, but nothing ridiculous. I wish I could just leave it on all the time, though.

I saw the official OpenVPN app, but since it's through the regular App Store, it's a hassle to get the configuration loaded. My VPN provides the config files all separately, and I was having a difficult time getting them all into a single .ovpn file. I got everything set up on the first try with the cydia version.
