I want to share some information around battery drain and android.  In my 
experience, the extra battery drain will come from using a TAP interface 
instead of a TUN interface.  What happens is the broadcast traffic as a 
result of a TAP interface keeps the android device awake because of hte 
constant chatter on the VPN.  I highly recommend that if someone is going 
to use a 'always on' vpn or in circumstances where they want the phone to 
sleep while the screen is off and tinc is running, that they use TUN 
instead.  THere is no broadcast traffic on TUN and I have found much better 
deep sleep.  In fact, with TAP, I was seeing near 100% AWAKE time on my 
device caused by wakelock bam_dmux_wakelock.  You also may want to consider 
adjusting the PingInterval in the tinc.confs to something more than 60 
seconds to keep chatter down.  I've set mine to 5 minutes intead (300 
seconds).  

Sorry for necroposting here but I thought it was important to augment the 
information in this thread with some experience that may help someone.
