I just hope I am not breaking any rules here (I have read the entire email the mods just sent me), since I just created my account and it will be my first post ever. I am sorry in advance. I just finished reading the entire 179 pages related to the Hidizs AP80, and I saw 2-3 people having problems with the battery longevity. It is the first of March, anyone else since then is having the same problems? I have been listening to the device since 8 this morning. It is 13h pm (1 pm) where I live and it will be a miracle if the battery last 6 hours of normal listening using FLAC. It is pretty far from the promised 15 hours. Am I doing something wrong? Is there a setting somewhere eating at my battery? Bluetooth is off, I don't see anything else. Its sad because I really enjoy the device except for a few problems. Like the wobbling knob and the device cannot scan my albums and create a playlist. I really think the battery will be totally dead in the following months. Is it possible to change it for a better one? Thank you for your time, have a nice day.
