Plug is bad

First, the performance of the battery - which is perfectly adequate as it is intended for emergencies only for me. Therefore, I have chosen as my small part. My Lumia 920 so you can once again invite you to 3/4.
The performance is also after half a year yet satisfactory!

This USB connector but was not really liked from the beginning - the matter is very shaky. But that did not bother me at first because the shop still worked. Meanwhile, however, I have serious problems with it - you Friemelt back and forth so that the cell phone contact with the Aku gets - but then move in no case more !!!!!
On the go in your pocket so impractical ......
