Battery drains after installed Openvpn for android.
I noticed Openvpn is very expensive by charge battery power.
please tune it , using less power, than we could play more times.

you could monitor the battery status, the issue can be easily produced.

Battery consumption is very dependent on your used VPN. If you have a keepalive 
10 60 settings which means two packets every 10 seconds. I have TCP VPN with 
keepalive 1800 4000 which has only a small drain on the battery.

Unfortunately the client cannot change the keepalive setting
