They said 10 hours at the beginning and this seems to be realistic. The battery has only 400 mAh (to make the slim design possible).
APE files have the same problem as FLAC files -> the first second is cut off.
I converted FLAC files to WAV with applied ReplayGain because the N1 has no function to normalize peaks.
My suggestions how the software could be improved:
- there should be an option to directly jump to the song that is playing via the main menu (maybe instead of the pointless Hi-Fi logo down right)
- the albums should be sorted by alphabet
- when the player is in hold mode, the display light should only light up for a short moment after touching the pad (or not light up at all) to save battery
And AAC support would be nice. For me, it's a lossy format with acceptable quality (at Q1.0/about 400 kbps).
