This is an understatement.

"Ingress is causing a surge in mobile power pack sales." Might hit closer to the mark. A majority of the high-level players I know are tethering a Nexus 7 to their phone, and attaching their phone to a mobile power pack. My phone gets slightly less than 1 hour on it's own.

I recently lost my extended backup battery and have certainly had battery drain issues. I was thinking that I might steal this guys idea: http://sphotos-b.xx.fbcdn.net/hphotos-snc6/201097_1015128278... from this post:http://www.reddit.com/r/Ingress/comments/14f4xw/power_for_ye...
