Nexus 7 Battery Fix

Two days ago I was on a business trip, traveling by train.While waiting for the train at the station my Nexus was working fine, 30min after I went on the train and wanted to watch a movie my Nexus was suddenly DEAD. Like DEAD DEAD. Only thing that worked was the background light. So I googled a bit and found that many Nexus suffer from a loose battery connection.

Fixing it is easy, just open the case (use a small knife etc, the rest is like opening a smartphone) and fix the connection (see pic)

And c'est tout!
