I charged my device with wall charger (5V/1.5A) for 24 h and with rear USB on PC.
Few days ago, orange LED finally goes off after 3 hours of charging. But today (after 2 days since charging) my battery is almost empty. Maybe, I should try few more charging/discharging cycles. Is this "normal" behavior of new device?
Booxtor, I really appreciate your help. I see that you helped many people on this forum. I dont want to be unfair to you, so I want you to know that I bought my device from ARTHATECH.
Thank you again, maybe we can solved my problem.
