Battery and quality

I gelaubt the positive reviews, but since the camera is recording sound and image offset is this highest of sound recordings free to use it.

But what most bothers that the battery is not properly load and after a short time already goes blank. According to operating load transfer for 2-4 hours, then it is full. Did it veruscht over outlet and computer. Invites both times only to 1 bar and is also immediately empty. I have it easy ma an entire day trying to no avail.
A 2nd model ordered ... the same error

For small-screen test purposes to berauchen, but rather spend 30-40 more and buy something useful. Pure Geldveschwedung.
