battery stops charging after a few seconds (nexus 5) - any hints?
- 
 I have purchased a nexus 5 with ubuntu touch preinstalled. The charging problem occurred right away. I was able to reinstall the system, but this did not change anything in the problem. Regardsless which cable I use, the battery will show that it is charging for a few seconds, maybe 3 or 4 seconds, then stops. What can I do? 
 Thanks
 Andreas
