Ich hab bei ZOOM angefragt. Hier die Antwort:
Hello,
While some early, models of the H1 had a battery drain issue, in that case, the battery would drain completely in a couple of days without using the device. A loss of one battery bar after 3-4 weeks does not resemble this issue, and is normal operation. If this presents an issue, we would recommend removing the battery if the device will not be used for an extended period of time.
Let me know if you have any questions.
Sincerely,
CUSTOMER SUPPORT
