The results: I will update as I complete more tests. Testing details are at the end of this post. While I understand FLAC and OGG files use more power, is there any chance a firmware update can help to close the gap in battery life between playing MP3s and FLAC files? 6-7 hours is rather disappointing.īeing curious how long my Clip’s battery lasts while playing certain bitrate songs, I started conducting tests. By contast, by playing 128kbps MP3s, the battery lasts at least twice as long (around 14 hours). I also have the new 8GB clip and find that I get about 6-7 hours of battery life when playing FLAC files (with Etymotic ER6iheadphones). Lets say all tracks at 128kbps mp3 at about 50% volume with standard headphones that came with the player. Is the battery drain so high when playing lossless on high volume/impedance headphones? If so, about how much in comparison with a normal situation. Only 5h of total playback time then? Should i change to an lossy format (for example ogg) and a pair of IEM’s to maximize the battery playback time? My battery level dropped in about 1h playback from 80% to 60%. How much battery playback time can i expect? I preffer high volume setting at about 90%. Also my pair of headphones (Koss KSC75) are high impedance (60 ohm). All my music is in flac format(~900kbps). Maximum recording time is 8 hours per single recording.I only managed to play 2 hours of music on it. Initial charge was about 80%.
