Huge battery and data drain.

First the good news is that it runs “out of sight, out of mind”, which I guess is good. The bad news is that when I look at my device stats this app uses about 50-75% of my battery every day and used about 15GB of data for the month. I’ll be honest, I’m not entirely sure what it’s supposed to do but I know it’s physically costing me money since I now have to charge my phone 2x per day.

READ: Battery Usage and link scans and network usage

I’ve seen a significant amount of reviews complaining about “High battery usage” and “5k links?? I only used one app!” iOS tracks “battery usage” based on network activity, and because this acts as a VPN, yes, it will show high battery usage, but in reality it’s not. Let’s say Facebook used 10% battery, and Instagram used 15% battery, after installing this app, you’d see iOS report that this app used 25% of your battery. I’m sure you get the idea now. You can validate this information by using any VPN client on your phone. Link scans: This is all traffic from your phone: background app refreshes, apps can send request to hundreds of separate links. That’s why you see so many link scans.

Network usage: again, because all apps route their data into this app, your data usage will be pointed to this app aswell. If you used 5GB on Facebook, it would show as 5GB under this app.

Good overall app, for all your devices. The vpn option stopped working after I upgraded to ios 16 for some reason. Even though the iPhone shows the vpn icon, and it shows it’s connected in the settings but there’s no vpn server. I maybe missing something but not using for now….

vpn is working again. Updating to 4 star. For several days a lot of iPhones/MacBook users did not have vpn, even though their iPhone showed they did. Back to using the app
