I generally use a VPN 100% of the time on my laptop. It doesn't provide a ton of extra privacy by itself, but it combines my traffic with that of a large numbers of others. And by using browser extensions such as ublock, umatrix, and privacy badger, I can feel a little more peace of mind about being constantly watched. On mobile, it's a different story. I'm not sure about iOS, but on unrooted Android phones, I don't believe there is a way to route IPv6 traffic over a VPN so you are a bit more limited from information gathering via that route. Also, VPN clients eat a lot of battery so useability goes down. My solution for that is to limit my use of mobile devices. Edit: clarified a statement
