Hi

Thanks for great work with Wireguard, it's fresh breeze of air compared on years spend on OpenVPN...

I am testing WG on varius OSes and devices and I have noted severe battery drain on iOS (12.2, iPhone 8). Typically battery drops 40% during night-time (that is 7 hours of inactivity on the phone) when WireGuard is engaged.
Is this some kind of known issue? I did not had chance to test previous iOS version without SIMD ChaCha20 support so i cannot tell if it is becouse of the last update.

Anything i can do to track issue here?

thanks,
