Still showed the battery indicator "Full" on.
So I tried to drive it to the extreme and even 90 shots, most of Streak and 2x 5 minute video afterward pushed.
The subsequent display of images including background music forced the battery is not in the knee.
Only one more photo session gave after 20 pictures a flashing red battery indicator on the PEN.
I am very happy and I can not tell the difference from the original date.
Was a protective cap for the gold contacts, as it should be, attached.
So what you want more?
